political influence motives and the choice between tariffs and quotas abstract tariffs and quotas are not symmetric under a variety of circumstances this paper pursues the implications of one such circumstance domestic market power for the political choice of protectionist instrument in the context of a political support maximization model tariffs dominate quotas in the political model in the absence of revenue seeking motives in the presence of revenue seeking ambiguity arises but limits can be placed on the range of tariff or quota levels also some welfare implications emerge

the role of feelings in investor decision making abstract this paper surveys the research on the influence of investor feelings on equity pricing and also develops a theoretical basis with which to understand the emerging findings of this area the theoretical basis is developed with reference to research in the fields of economic psychology and decision making recent advancements in understanding how feelings affect the general decision making of individuals especially under conditions of risk and uncertainty e g loewenstein et al 2001 psychological bulletin 127 267 286 are covered by the review the theoretical basis is applied to analyze the existing research on investor feelings e g kamstra et al 2000 american economic review forthcoming hirshleifer and shumway 2003 journal of finance 58 3 1009 1032 this research can be broadly described as investigating whether variations in feelings that are widely experienced by people influence investor decision making and consequently lead to predictable patterns in equity pricing the paper concludes by suggesting a number of directions for future empirical and theoretical research

do stock markets catch the flu we examine the impact of influenza on stock markets for the united states a higher incidence of flu is associated with decreased trading decreased volatility decreased returns and higher bid ask spreads consistent with the flu affecting institutional investors and market makers the decrease in trading activity and volatility is primarily driven by the incidence of influenza in the greater new york city area however the effect of the flu on bid ask spreads and returns is related to the incidence of flu nationally international data confirm our findings of a decrease in trading activity and returns when flu incidence is high

is it time to split the s p 500 futures contract by october 1996 the value of the s p 500 index futures contract had grown to five times its value at its inception in april 1982 one way to make the contract more accessible to small investors and to smooth out trading is to split the contract splitting the contract could increase transaction costs although competition would probably limit the amount of the increase less clear is the need for increasing the minimum percentage tick size the current minimum tick size is small for s p 500 futures compared with that of other futures and also common stocks the larger tick size could affect volume however by increasing trading costs and reducing the willingness to trade

day of the week effects and asset returns the number of empirical studies using daily stock returns is rapidly increasing researchers generally assume that the distribution of stock returns is identical for all days of the week a convenient statistical assumption but not a necessary condition of market equilibrium nevertheless there are reasons to suspect that the distribution of returns may vary according to the day of the week the most obvious is the impact of weekends on monday s return since monday s return is calculated over three instead of one calender day the mean and variance may well be higher on monday compared with any other daily return perhaps three times as large previous research has examined the daily distribution of stock returns for a monday effect while fama 1965 does not compare daily mean returns he does report that monday s variance is about 20o greater than other daily returns with a traditional distributional assumption regarding the returns on a financial asset specifies that the expected returns are identical for all days of the week contrary to this plausible assumption this paper discovers that the expected returns on common stocks and treasury bills are not constant across days of the week the most notable evidence is for monday s returns where the mean is unusually low or even negative several explanations of the results are investigated but none proves satisfactory aside from documenting significant day of the week effects the implications of the results for tests of market efficiency are examined while market adjusted returns continue to exhibit day of the week effects these effects are no longer concentrated on monday during the last year we have had many conversations with our colleagues throughout the professions we are particularly thankful to the participants at sessions of the western and american finance associations where preliminary versions of this paper were presented special thanks are due to gene fama gailen hite jon ingersoll robert jarrow merton miller clifford smith and rex thompson the expert research assistance of frank rabinovitch and youngsup yun is gratefully acknowledged 1 the list of papers using daily stock returns is too long to name recent examples include charest 1978 dodd 1980 banz 1981 and reinganum 1981

weather and intraday patterns in stock returns and trading activity abstract we examine the relation between weather in new york city and intraday returns and trading patterns of nyse stocks while stock returns are found to be generally lower on cloudier days cloud cover has a significant influence on stock returns only at the market open there are significantly more seller initiated trades when there is more cloud cover at the market open which is consistent with the return results cloudy skies are associated with higher volatility and less market depth over the entire trading day finally cloud cover is not significantly correlated with spread measures and turnover ratios the findings overall suggest that weather has a significant influence on investors intraday trading behavior

sports sentiment and stock returns this paper investigates the stock market reaction to sudden changes in investor mood motivated by psychological evidence of a strong link between soccer outcomes and mood we use international soccer results as our primary mood variable we find a significant market decline after soccer losses for example a loss in the world cup elimination stage leads to a next day abnormal stock return of 49 basis points this loss effect is stronger in small stocks and in more important games and is robust to methodological changes we also document a loss effect after international cricket rugby and basketball games this paper employs a novel mood variable international soccer results to investigate the effect of investor sentiment on asset prices using a cross section of 39 countries we find that losses in soccer matches have an economically and statistically significant negative effect on the losing country s stock market for example elimination from a major international soccer tournament is associated with a next day return on the national stock market index that is 38 basis points lower than average we also document a loss effect after international cricket rugby and basketball games on average the effect is smaller in magnitude for these other sports than for soccer but is still economically and statistically significant we find no evidence of a corresponding effect after wins for any of the sports that we study controlling for the pre game expected outcome we are able to reject the hypothesis that the loss effect after soccer games is driven by economic factors such as reduced productivity or lost revenues we

reconsidering the impact of national soccer results on the ftse 100 in past decades many empirical studies revealed return anomalies in many different asset classes and markets very recent publications have however even found evidence that stock markets react to the results of soccer matches in this article we argue that such empirical studies should be analysed carefully we thus endorse the use of replication studies to verify results consequently by rebuilding the study of ashton et al 2003 we are able to detect mistakes in the empirical set up based on these findings we demonstrate how even minor flaws can have a crucial influence on the results of such studies and point out pitfalls that are frequently encountered we furthermore emphasize the importance of robustness checks to validate the results of empirical studies

the effect of time induced stress on financial decision making in real markets the case of traffic congestion abstract we study the role of stress induced by time constraints on investor decision making in real financial markets we use unexpected traffic congestion as a stress trigger our dependent variable is the slope of the implied volatility function ivf of options on russian trading system index rtsi futures at the left hand side of the volatility smile cf bollen and whaley 2004 controlling for relevant factors we find that this slope at the opening of the main trading session is higher subsequent to morning traffic jams suggesting that investors under stress assign higher weights to extreme loss scenarios this effect is economically exploitable before transaction costs

information quality and market efficiency the purpose of this paper is to analyze the optimal individual behavior in acquiring infor mation and to determine the amount of information incorporated in a stock at equilibrium in the presence of a cost schedule in acquiring information our paper shows that at equi librium the cost to acquire information that is not already incorporated in the price de pends only on the representative investor s risk preferences it follows that the marginal information costs are the same across all stocks at equilibrium even though the stock s information costs schedules may differ this suggests that the prices of small stocks may not incorporate all publicly available information this paper also provides empirical evi dence that newspapers publication of publicly available information can affect the stock prices

temperature shocks and the cost of equity capital implications for climate change perceptions financial market information can provide an objective assessment of losses anticipated from temperature changes in an apt model in which temperature shocks are a systematic risk factor the risk premium is significantly negative loadings for most assets are negative and asset portfolios in more vulnerable industries have stronger negative loadings on a temperature shock factor weighted average increases in the cost of equity capital attributed to uncertainty about temperature changes are 0 22 percent implying a present value loss of 7 92 percent of wealth these costs represent a new channel that may contribute to cost of climate change assessment

speculative prices and popular models t he rational expectations revolution in economics was born of the recognition that the expectations people hold for future economic variables are fundamental to their behavior thus our economists economic models require their those who make up the economy economic models models which they use to generate their expectations the key idea of rational expectations models is to collapse the two models into one to assume that people know or behave as if they know the true model that describes the economy this idea allows economists to construct simple and elegant models of the economy models that are appealing theoretically and that can be studied without collecting any data about the models in the minds of economic actors the problem with the rational expectations models is that collapsing the two kinds of models into one is a gross oversimplification obviously the popular models the models that are used by the broad masses of economic actors to form their expectations are not the same as those held by economists once one accepts the difference economic modelling cannot proceed without collecting data on the popular models themselves this paper reports on such a data collection effort on popular models using questionnaire survey methods with the purpose of understanding speculative markets i will report here on my research to understand the u s stock market crash of october 1987 research fumiko konya yoshiro tsutsui and i undertook to understand the japanese stock market crash of october 1987 research karl case and i undertook to understand recent real estate booms and research john pound and i undertook to understand the periodic hot markets for initial public offerings ipo s of common stock

conversation information and herd behavior experimental evidence shows that an important reason why people tend to imitate others to exhibit herd behavior is that they assume that the others have information that justifies their actions the information cascade models of banerjee 1992 and bikhchandani et al 1992 are significant developments in showing some general equilibrium and welfare effects of such rational imitative behavior but these models as specified may be of limited applicability since they assert that differences across groups in herd behavior can be attributed to the random decisions of first movers differences across groups in herd behavior might be explained more often in terms of different modes of interpersonal information transmission patterns of human conversation imply great selectivity to the kinds of information transmitted within groups this abstract was borrowed from another version of this item

mood induced variation in risk preferences abstract psychological research links good bad mood with increased decreased risk aversion this relation has been widely documented in experimental setups there has not been however a complementary analysis with real life decisions data this paper fills this gap by testing the relation between mood and risk attitude in capital markets to shed light on that relation we recover risk preferences from capital market data and employ accumulated evidence suggesting that people s mood is correlated with weather conditions corroborating established experimental evidence we find that good bad mood is associated with investors being less more willing to tolerate risk

the stock market effect of air pollution evidence from china abstractin financial studies environmental stimuli such as sunshine temperature and daylight are often used as proxies for people s collective mood swings to test their effects on the stock market china has experienced serious air pollution problems in recent years and chinese public awareness of air pollution has soared in this paper we use china as a natural experiment to investigate the effect on stock returns of depressed moods induced by air pollution daily air pollution data from 2005 to 2014 are analysed and the results obtained from the empirical research show that a contemporaneous negative and a two day lagged positive relationship exists between air pollution levels and stock returns over this time period the relationship is mediated by the influence of air pollution on investment decisions the results also indicate that the effect is weakened for companies that protect air quality but no stronger effect is detected for polluting companies the findings imply that air pollution is a

internationalization of western venture capitalists into emerging markets risk assessment and information in india this paper provides the first analysis of the internationalization of venture capital firms through an examination of risk assessment and information usage by firms in india personal interviews were conducted with executives in 31 84 of the active venture capital firms the paper extends previous research by comparing perceptions of the behavior of domestic venture capital firms in india foreign primarily u s venture capital firms in india and u s venture capital firms in their domestic markets foreign firms in india place significantly greater emphasis on product market factors and accountants reports than domestic firms in india they place significantly less emphasis on financial contributions of management in assessing risk and own due diligence and information from entrepreneurs than do u s firms in their domestic market they make more use of information from trade publications and relating to production capacity and technology and information from accountants reports than do domestic venture capital firms in india the evidence is consistent with venture capital firms adapting to local market conditions rather than implementing recipes from their domestic markets

conditional heteroscedasticity in time series of stock returns evidence and forecasts this article presents new evidence about the time series behavior of stock prices daily return series exhibit significant levels of second order dependence and they cannot be modeled as linear white noise processes a reasonable return generating process is empirically shown to be a first order autoregressive process with conditionally heteroskedastic innovations in particular generalized autoregressive conditional heteroskedastic garch 1 1 processes fit to data very satisfactorily various out of sample forecasts of monthly return variances are generated and compared statistically forecasts based on the garch model are found to be superior copyright 1989 by the university of chicago

analyzing the analysts career concerns and biased earnings forecasts this paper examines the career concerns of security analysts we relate long histories of their earnings forecasts to job separations we find that relatively accurate past forecasts lead to favorable career outcomes such as remaining at or moving up to a high status large prestigious brokerage house controlling for accuracy optimistic forecasts relative to the consensus increase the chances of favorable job separations job separations depend much less on accuracy for analysts who cover stocks that are underwritten by their brokerage houses such analysts are also much more likely to be rewarded for optimistic forecasts than other analysts furthermore job separations were much less sensitive to accuracy and somewhat more sensitive to optimism during the stock market mania of the late 1990s these findings suggest that the well documented analyst forecast optimism bias is likely due to incentives to promote stocks

investor mood herding and the ramadan effect in view of evidence linking herding and social mood we examine whether the positive mood documented during ramadan translates into higher herding compared to non ramadan days drawing on a sample of seven majority muslim countries we report significant herding during ramadan in most of our sample markets additionally we show that herding appears significantly stronger within rather than outside ramadan for most tests whereby its significance is manifested on both ramadan and non ramadan days overall herding significance within outside ramadan exhibits some variation in its levels across markets in relation to variables reflective of market states both domestically market returns market volume and internationally us market returns us investors sentiment global financial crisis market states

does the sun shine on art prices this paper examines how variation in mood influences subjective risk and hence auction prices for art in london during the period 1990 2007 the private value of an object is closely related to taste and mood which is proxied for by the variation in weather using a unique data set that includes presale estimates for paintings sold through sotheby s and christie s auction houses as well as weather data for london from the british atmospheric data centre we find that the lower part of the price distribution is populated with paintings with a relative high private value whereas in the upper part prices are driven primarily by the common value characteristics our findings have important implications for collectors and investors in the art market

stock market returns a note on temperature anomaly this study investigates whether stock market returns are related to temperature research in psychology has shown that temperature significantly affects mood and mood changes in turn cause behavioral changes evidence suggests that lower temperature can lead to aggression while higher temperature can lead to both apathy and aggression aggression could result in more risk taking while apathy could impede risk taking we therefore expect lower temperature to be related to higher stock returns and higher temperature to be related to higher or lower stock returns depending on the trade off between the two competing effects we examine many stock markets world wide and find a statistically significant negative correlation between temperature and returns across the whole range of temperature apathy dominates aggression when temperature is high the observed negative correlation is robust to alternative tests and retains its statistical significance after controlling for various known anomalies

seasonal darkness and ipo abstract this paper analyses the possible relationship between a particular natural phenomenon the shortening of light hours in autumn and a financial issue the level of underpricing recorded on the first day of listing by the companies subject to initial public offering ipo it analyses a sample of 3102 ipos in 32 countries in the period between january 1 2006 and december 31 2016 the empirical evidence supports the assumption that seasonal darkness when there is a lack of light has a positive impact on the raw initial returns of the ipos made during this period the results obtained confirm the previous studies aimed at investigating the phenomenon suggest a possible behavioral interpretation and in conclusion make a positive contribution deriving from the large sample size the consideration of different latitudes and the assumed perspective

asset pricing with beliefs dependent risk aversion and learning abstract this paper studies equilibrium in a pure exchange economy with unobservable markov switching growth regimes and beliefs dependent risk aversion bdra risk aversion is stochastic and depends nonlinearly on consumption and beliefs equilibrium is obtained in closed form the market price of risk the interest rate and the stock return volatility acquire new components tied to fluctuations in beliefs a three regime specification is estimated using the generalized method of moments gmm model moments match their empirical counterparts for a variety of unconditional moments including the equity premium stock returns volatility and the correlations between stock returns and consumption and dividends dynamic features of the data such as the countercyclical behaviors of the equity premium and volatility are also captured model volatility provides a good fit for realized volatility a new factor the information risk premium is found to be a strong predictor of future excess returns these results are obtained with an estimated risk aversion fluctuating between 1 44 and 1 93

is it the weather response abstract kamstra kramer and levi kkl in their comment seem to miss the main point of our paper many things are correlated with the seasons so it is difficult to distinguish between them when we try to explain the well known summer winter pattern in stock returns finding an isolated seasonal affective disorder sad effect without proper control variables does not disprove our point but strengthens it to sidestep all of the issues they raise and take our point to the extreme we show using plain vanilla regressions that the seasonal stock market pattern they attribute to sad can also be explained by variables like ice cream consumption or airline travel the new variations of sad variables onset and incidence kkl propose in their recent work for north america are even more problematic than the original sad variables we find that these new sad proxies are not significant in countries where according to kkl they should be canada and the united states

incremental protection and efficient political choice between tariffs and quotas this paper offers a new political economy explanation for the increasing use in recent years of quotas instead of or in combination with tariffs as a form of trade protection we show that under domestic monopoly the comparative efficiency of tariffs and quotas in achieving political objectives will vary depending on the nature of the mark et and the level of protection at high levels of protection quotas can become more politically efficient than tariffs we also show that at low levels of protection a price equivalent quota may not exist

a theory of expropriation and deviations from perfect capital mobility there are many reasons why commodity trade fails to equate the rewards to factors of production in different countries consequently there is an incentive for factor movements between countries while movements of factors especially capital are important in the world economy they have not been sufficient to equate factor returns among countries the failure of capital flows to equate returns to capital is frequently attributed to political risks and left outside the sphere of economic analysis specifically investments abroad especially in ldc s are said to be more subject to the risk of expropriation or at least to unpredictable changes in the tax and exchange control regime adopted by the host country fears of foreign investors have often been realised williams i975 estimates that about 20 of the value of foreign investments carried into or made during i956 72 in ldc s was expropriated without compensation in this period in the past researchers in disciplines other than economics have been responsible for most of the analysis of expropriations we argue that an important set of economic considerations affect the nature of these impediments to capital mobility and this paper provides a theory of expropriation based on maximising behaviour by host countries and investors we use this theory to identify industry and national characteristics increasing the threat of expropriation and implying large deviations from equal returns on capital and to examine host country and home country policies minimising distortions from the threat of expropriation three broad conclusions follow from the analysis first the threat of expropriation can significantly distort the international allocation of capital even if the act of expropriation is relatively rare in the extreme acts of expropriation would never occur in a world of perfect foresight and rational decision making yet actions by investors to ensure that countries do not expropriate would be distorting second the ability of a country s government to expropriate foreign investments may actually reduce its welfare furthermore a host may be better off if home governments can retaliate against an expropriating country indeed an increase in the penalty imposed on an expropriating country may increase its welfare a government s power to expropriate after investments are made may alasdair smith and an associate editor made numerous valuable suggestions we would also like to thank g m grossman r w jones l a sjaastad n h stern and j e stiglitz for comments much of eaton s work on this paper was completed while he was a visitor at the graduate institute for international studies geneva an earlier version of this paper appeared under the same title as rpds

market efficiency bounded rationality and supplemental business reporting disclosures the aicpa special committee on financial reporting has urged disclosure of relevant forward looking information on risks and opportunities to supplement conventional financial statements we conduct a laboratory market experiment to assess the effects of such disclosures on capital allocation decisions we develop two sets of competing hypotheses regarding how capital markets react to supplemental disclosures one set is based on the assumption of semi strong market efficiency while the other posits that the bounded rationality of individual traders leads to inefficient market prices we find that explicit disclosure of management s best estimate of an uncertain quantity improves market efficiency even though this disclosure is redundant with information in financial statements second we find disclosure of an upper bound of management s estimate has the potential to bias security prices upward while informationally equivalent disclosure of both upper and lower bounds removes this bias these results suggest that experimental market reactions to these supplemental disclosures are inconsistent with market efficiency supplemental analyses of individuals price predictions and trading behavior support our conclusion that inefficiencies are at least partially attributable to individual information processing biases

fear anger and credit on bank robberies and loan conditions we study the impact of emotions on real world decisions made by loan officers by analyzing the loan conditions of loans granted immediately after a bank branch robbery we find significant differences in conditions of the loans granted after a robbery compared to changes in loan conditions that occur contemporaneously at unaffected branches in general loan officers seem to adopt so called avoidance behaviour in accordance with the literature on posttraumatic stress their avoidance behavior is halved within two weeks after the robbery and the effect further varies depending on the presence of a firearm during the robbery

contagious speculation and a cure for cancer a nonevent that made stock prices soar a sunday new york times article on a potential development of new cancer curing drugs caused entremed s stock price to rise from 12 063 at the friday close to open at 85 and close near 52 on monday it closed above 30 in the three following weeks the enthusiasm spilled over to other biotechnology stocks the potential breakthrough in cancer research already had been reported however in the journal nature and in various popular newspapers including the times more than five months earlier thus enthusiastic public attention induced a permanent rise in share prices even though no genuinely new information had been presented a central tenet of f inancial economics is that an asset should trade at the risk adjusted present value of its expected future cash f lows these expected future cash f lows exist in people s minds and do not normally lend themselves to direct observation an equilibrium price in a frictionless market does not tolerate disagreements among market participants if some people deem the price too low they will buy the asset if others think it is too high they will sell it short if necessary although the efficient markets hypothesis predicts that price changes are unpredictable it associates them with changes in traders beliefs about future cash f lows or the appropriate discount rate beliefs change with the arrival of new information thus in hindsight at least we should be able to ascribe price changes to the arrival of specific new information we examine this view in the context of a series of news reports in the media pertaining to entremed enmd a biotechnology company and other members of its sector the sunday may 3 1998 edition of the new york times reports on a recent breakthrough in cancer research and mentions enmd a company with licensing rights to the breakthrough kolata 1998 the story s impact on the stock prices was immediate huge and to a large extent permanent the new news content of the times story was nil though the substance of the story had been published as a scientific piece in nature boehm et al 1997 and in the popular press including the times itself wade 1997 more than five months earlier in november 1997

investor mood and financial markets abstract numerous studies in recent decades have linked investor mood and financial market behavior but most works have been empirical investigations this paper bridges the gap between empirical findings and financial theory by slightly modifying the lucas lucas r e 1978 asset prices in an exchange economy econometrica 46 1429 1445 model this study shows how investor mood variations affect equilibrium asset prices and expected returns analysis results indicate that both equity and bill prices correlate positively with investor mood with higher asset prices associated with better mood conversely expected asset returns correlate negatively with investor mood further the mood effect on asset prices increases when investors are in a good mood and mood variations exhibit a greater influence on equity markets than on bill markets results of this study suggest that investor mood is a vital factor in equilibrium asset prices and returns and integrating investor mood into asset pricing models helps to interpret the growing body of seemingly anomalous evidence regarding investor behavior

patterns in stock market movements tested as random number generators this paper shows that tests of random number generators rngs may be used to test the efficient market hypothesis emh it uses the overlapping serial test ost a standard test in rng research to detect anomalous patterns in the distribution of sequences of stock market movements up and down our results show that most stock markets exhibit idiosyncratic recurrent patterns contrary to the efficient market hypothesis also that ost detects a different kind of non randomness to standard econometric long and short memory tests exposure of these anomalies should contribute to making markets more efficient

in the mood to consume effect of sunshine on credit card spending abstract using a large representative sample of high frequency credit card transactions in the united states this paper examines the causal effect of sunshine induced mood on contemporaneous household credit card spending we document a 0 3 percent increase in credit card spending in response to a one unit increase in the same day local abnormal sunshine the spending response is stronger for consumers with higher credit card debt lower fico score and shorter tenure with the bank the effect manifests in long term durable goods spending and is not driven by other weather conditions complementarity between sunshine and consumption or intentional choice of consumption time we document similar responses of spending on seasonal and non seasonal goods and during times with high and low sunshine levels finally the sunshine effect occurs among consumers with various characteristics

mood firm behavior and aggregate economic outcomes abstract this study examines whether mood affects the aggregate state level macroeconomy through its impact on firm level decisions using sky cloud cover as a proxy for mood we show that mood affects the economic expectations of small business managers after relatively sunnier periods managers have more optimistic expectations and the component of their expectations related to mood influences hiring and investment decisions consequently mood affects state level job creation and new business starts especially during periods of greater economic uncertainty these results suggest that mood induced economic expectations influence firm level managerial decisions and state level macroeconomic fluctuations

start up ventures towards the prediction of initial success abstract there are numerous studies on new product activities that try to measure the relative impact of different factors on success or failure the research on new ventures is less comprehensive and often only a few items are considered this article reports on the early results from a research program that is combining the research on both new products and new ventures to come up with a more comprehensive evaluation of relative success factors the literature was reviewed to determine the most significant factors found in prior work a 68 item questionnaire was developed and used with the chief executives of 24 new technical ventures all associated with the rpi incubator or technology park ten of the 17 factors investigated yielded reliable measurements which were then subjected to siepwise regression analysis to determine the relative impact of each factor on the two success measurements used initial quantified success and initial subjective success it should be recognized that initial success does not necessarily predict ultimate success an area to be investigated in continuing studies the two success measurements were not correlated and the correlations with the independent variables were therefore different initial quantified success showed a strong negative correlation with market attractiveness companies entering smaller or more slowly growing markets were doing better than those in the larger faster growing markets initial quantified success was positively correlated with the level of entrepreneurial characteristics exhibited by the leader s these were the only two variables exhibiting significant relationships with quantified success initial subjective success was negatively correlated with market dynamism rather than market attractiveness negative correlation was also measured with both r d intensity and the organic nature of the firm this latter finding is contrary to much of the new product literature which emphasizes the need for individual independence and initiative such may be the case with new products or ventures within large organizations but in small independent ventures the entrepreneur should provide strong control and guidance a positive correlation was observed with the entrepreneurial characteristics and also with the degree of match between the firm s experience and the new business requirements no significant correlation was observed with 1 product or service uniqueness 2 gross margin or 3 strategic aggressiveness the lack of correlation with these variables is surprising but it may be due to the small size of the sample the research confirmed two items that are understood by most scholars and experienced practitioners the importance of the entrepreneur and the importance of pursuing new ventures that match the technical and market experience of the team the less obvious results are those that suggest that success is favored by strong review and control by the entrepreneur rather than the development of employee initiative and independence also the initial success appears to be coming more readily to firms in more slowly growing or less dynamic markets it will take an expanded sample and a longer time horizon to determine if these initial trends continue to ultimate success

evidence for countercyclical risk aversion an experiment with financial professionals countercyclical risk aversion can explain major puzzles such as the high volatility of asset prices evidence for its existence is however scarce because of the host of factors that simultaneously change during financial cycles we circumvent these problems by priming financial professionals with either a boom or a bust scenario subjects primed with a financial bust were substantially more fearful and risk averse than those primed with a boom suggesting that fear may play an important role in countercyclical risk aversion the mechanism described here is relevant for theory and may explain self reinforcing processes that amplify market dynamics jel e32 e44 g01 g11 g12

bank run psychology abstract banks are inherently susceptible to panics and bank runs due to the problem of maturity mismatch resulting in both a stable equilibrium in which the bank survives and an unstable equilibrium in which a bank run occurs understanding equilibrium selection in this setting is extremely important for safeguarding financial stability in this paper one new potential factor that determines whether a bank runs gets triggered or not is experimentally studied namely the psychological state of the depositor prior to participating in an experimental bank run game subjects are either induced with fear sadness or happiness using an autobiographical emotion induction task the findings suggest that the presence of background fear significantly increases the likelihood of withdrawal and a subsequent bank run in addition women are shown to be significantly more likely to withdraw then men but only in the fear induction treatment

good day sunshine stock returns and the weather psychological evidence and casual intuition predict that sunny weather is associated with upbeat mood this paper examines the relationship between morning sunshine in the city of a country s leading stock exchange and daily market index returns across 26 countries from 1982 to 1997 sunshine is strongly significantly correlated with stock returns after controlling for sunshine rain and snow are unrelated to returns substantial use of weather based strategies was optimal for a trader with very low transactions costs however because these strategies involve frequent trades fairly modest costs eliminate the gains these findings are difficult to reconcile with fully rational price setting

poker player behavior after big wins and big losses we find that experienced poker players typically change their style of play after winning or losing a big pot most notably playing less cautiously after a big loss evidently hoping for lucky cards that will erase their loss this finding is consistent with kahneman and tversky s kahneman d a tversky 1979 prospect theory an analysis of decision under risk econometrica47 2 263 292 break even hypothesis and suggests that when investors incur a large loss it might be time to take a vacation or be monitored closely

is it the weather we show that results in the recent strand of the literature which tries to explain stock returns by weather induced mood shifts of investors might be data driven inference more specifically we consider two recent studies kamstra mark j kramer lisa a levi maurice d 2003a winter blues a sad stock market cycle american economic review 93 1 324 343 cao melanie wei jason 2005 stock market returns a note on temperature anomaly journal of banking and finance 29 6 1559 1573 that claim that a seasonal anomaly in stock returns is caused by mood changes of investors due to lack of daylight and temperature variations respectively while we confirm earlier results in the literature that there is indeed a strong seasonal effect in stock returns in many countries stock market returns tend to be significantly lower during summer and fall months than during winter and spring months as documented by bouman and jacobsen bouman sven jacobsen ben 2002 the halloween indicator sell in may and go away another puzzle american economic review 92 5 1618 1635 there is little evidence in favor of a sad or temperature explanation in fact we find that a simple winter summer dummy best describes this seasonality our results suggest that without any further evidence the correlation between weather related variables and stock returns might be spurious and the conclusion that weather affects stock returns through mood changes of investors is premature

market mechanisms in online peer to peer lending online peer to peer lending p2p lending has emerged as an appealing new channel of financing in recent years a fundamental but largely unanswered question in this nascent industry is the choice of market mechanisms i e how the supply and demand of funds are matched and the terms price at which transactions will occur two of the most popular mechanisms are auctions where the crowd determines the price of the transaction through an auction process and posted prices where the platform determines the price while p2p lending platforms typically use one or the other there is little systematic research on the implications of such choices for market participants transaction outcomes and social welfare we address this question both theoretically and empirically we first develop a game theoretic model that yields empirically testable hypotheses taking into account the incentive of the platform we then test these hypotheses by exploiting a regime change from auctions to posted prices on one of the largest p2p lending platforms consistent with our hypotheses we find that under platform mandated posted prices loans are funded with higher probability but the preset interest rates are higher than borrowers starting interest rates and contract interest rates in auctions more important all else equal loans funded under posted prices are more likely to default thereby undermining lenders returns on investment and their surplus although platform mandated posted prices may be faster in originating loans auctions that rely on the crowd to discover prices are not necessarily inferior in terms of overall social welfare this paper was accepted by chris forman information systems

do weather induced moods affect the processing of earnings news we investigate whether unpleasant environmental conditions affect stock market participants responses to information events we draw from psychology research to develop a new prediction that weather induced negative moods reduce market participants activity levels exploiting geographic variation in equity analysts locations we find compelling evidence that analysts experiencing unpleasant weather are slower or less likely to respond to an earnings announcement relative to analysts responding to the same announcement but experiencing pleasant weather price association tests find evidence consistent with reduced activity due to weather induced moods delaying equilibrium price adjustments following earnings announcements we also use our analyst based research design to re examine an existing prediction that unpleasant weather induces investor pessimism and find evidence of both analyst pessimism and reduced activity in the presence of unpleasant weather together our study provides new evidence that both extends and reaffirms findings of a relation between unpleasant weather and market activities and contributes to the broader psychology and economics literature on the impact of weather induced mood on labor productivity this article is protected by copyright all rights reserved

winter blues a sad stock market cycle and god said let there be light and there was light and god saw that the light was good genesis 1 3 depression has been linked with seasonal affective disorder sad a condition that affects many people during the seasons of relatively fewer hours of daylight experimental research in psychology has documented a clear link between depression and lowered risktaking behavior in a wide range of settings including those of a financial nature through the links between sad and depression and between depression and risk aversion seasonal variation in length of day can translate into seasonal variation in equity returns based on supportive evidence from psychology which suggests sad is linked closely with hours of daylight we consider stock market index data from countries at various latitudes and on both sides of the equator we model differences in the seasonal variation of daylight across coun

income and wealth heterogeneity in the macroeconomy how do movements in the distribution of income and wealth affect the macroeconomy we analyze this question using a calibrated version of the stochastic growth model with partially uninsurable idiosyncratic risk and movements in aggregate productivity our main finding is that in the stationary stochastic equilibrium the behavior of the macroeconomic aggregates can be almost perfectly described using only the mean of the wealth distribution this result is robust to substantial changes in both parameter values and model specification our benchmark model whose only difference from the representative agent framework is the existence of uninsurable idiosyncratic risk displays far less cross sectional dispersion and skewness in wealth than u s data however an extension that relies on a small amount of heterogeneity in thrift does succeed in replicating the key features of the wealth data furthermore this extension features aggregate time series that depart significantly from permanent income behavior

rain emotions and voting for the status quo abstract do emotions affect the decision between change and the status quo we exploit exogenous variation in emotions caused by rain and analyze data on more than 870 000 municipal vote outcomes in switzerland to address this question the empirical tests are based on administrative ballot outcomes and individual postvote survey data we find that rain decreases the share of votes for political change our robustness checks suggest that this finding is not driven by changes in the composition of the electorate and changes in information acquisition in addition we provide evidence that rain might have altered the outcome of several high stake votes we discuss the psychological mechanism and document that rain reduces the willingness to take risks a pattern that is consistent with the observed reduction in the support for change

idiosyncrasies in australian petrol price behaviour evidence of seasonalities it has been argued that there are certain idiosyncrasies in australian petrol price behaviour to the extent that these idiosyncrasies result in large magnitude differences in petrol prices they may be exploited by consumers to significantly reduce their household expenditure on the product similarly such seasonalities may influence retailers in their purchase and storage decision the objective of this paper is to test for seasonalities in the australian retail petrol market the approach adopted is similar to that for determining calendar anomalies as documented in the financial and commodity markets literature we find that a monthly seasonal effect is pronounced with petrol prices lower in the months of february may and highest in july and august a day of the week effect is also apparent and is manifest in all petrol prices for capital cities adelaide brisbane melbourne and sydney across various years however the half month effect as is common in stock returns is not observed moreover contrary to popular belief that petrol prices are higher surrounding holidays no evidence of the holiday effect is found in brisbane and melbourne petrol prices also have some relationship to the mood of consumers as proxied using weather conditions this is not observed in adelaide and sydney

emerging strategies in the venture capital industry abstract this article reports a study of the future direction of the venture capital industry by examining the basic strategies and strategic assumptions of a broad sample of venture capital firms there are three main sets of results first the once homogeneous venture capital industry is rapidly dividing into several different strategic groups members of these groups are increasingly distinguishing themselves from other groups on four basic dimensions followed by member firms 1 financial resources equity capital comes from a greater variety of sources five major sources resulting in fundamentally different demands on the mission of the receiving venture capital firm 2 staff resources the way venture capital firms use staff resources particularly regarding investee management assistance is becoming increasingly varied across different groups some firms provide fewer than 2 days per year while others provide up to 450 man days per year per client 3 venture stages while the overall industry retains a primary interest in stage 1 2 and 3 investment specific firms vary considerably in the distribution of investment emphasis across these three stages 4 use of financial resources firms in the industry are becoming increasingly differentiated in the size of minimum investments they make 100 m to 1000 m and in their role as a direct investor versus a broker for institutional funds practicing venture capitalists should make use of this first set of findings in two ways first they may find it useful to compare their firm s orientation along these four strategic dimensions with those of the firm s that comprised this study second they may seek to use these four strategic dimensions as a basis on which they might examine clarify and or redefine the marketing strategy pursued by their firm a second set of results identified three goals and priorities of venture capital firms that have neither changed over time nor across increasingly different strategic groups annualized after tax return on investments of between 25 and 40 remain the most common objective across all firms a 5 to 6 year investment time horizon and a major emphasis on the quality of the management team in evaluating new deals were universal priorities across diverse venture capital firms a third finding in this study was that venture capital firms profess greater certainty about the future direction of the venture capital industry than the direction of their firm the most notable example of this is a strong sense that industry wide rates of return are headed downward yet few senior partners expect their firm to experience this decline practicing venture capitalists may be interested to peruse these results to see what trends are predicted within the venture capital industry by this subsample of that industry second they should consider the finding that industry wide rates of return are headed downward in light of the first two sets of findings to develop their own opinion about the future performance of different strategic groups within the industry it is important to note that the sample of venture capital firms on which this study was based did not include most of the larger older funds some of these funds would be characterized as industry leaders pace setters and innovators the sample provides a solid representation of the broad middle of the venture capital industry and newer entrants into the industry while larger older funds are under represented their impact on future trends and strategies in the industry is captured to some extent in the set of questions about future direction of the venture capital industry finally the emerging strategic groups in the venture capital industry that were identified by this study may be useful information for investors as well as users of venture capital for investors the opportunity to participate in venture capital activity should become more clearly understood and varied basically this study should help investors differentiate the strategic posture of different venture capital firms and funds on four factors rather than simply industry geographic considerations for users of venture capital the results of this study suggest a possibility for multiple options that are both more accessible and more catered to specific needs users of venture capital should find a clearer basis on which to differentiate venture capital firms in terms of venture stage priorities staff utilization orientations sources and uses of financial resources this should make for more informed shopping among different venture capital sources and provide a basis on which to shop for the most compatible firm

a model of venture capitalist investment activity the paper describes the activities of venture capitalists as an orderly process involving five sequential steps these are 1 deal origination the processes by which deals enter into consideration as investment prospects 2 deal screening a delineation of key policy variables which delimit investment prospects to a manageable few for in depth evaluation 3 deal evaluation the assessment of perceived risk and expected return on the basis of a weighting of several characteristics of the prospective venture and the decision whether or not to invest as determined by the relative levels of perceived risk and expected return 4 deal structuring the negotiation of the price of the deal namely the equity relinquished to the investor and the covenants which limit the risk of the investor 5 post investment activities the assistance to the venture in the areas of recruiting key executives strategic planning locating expansion financing and orchestrating a merger acquisition or public offering 41 venture capitalists provided data on a total of 90 deals which had received serious consideration in their firms the questionnaire measured the mechanism of initial contact between venture capitalist and entrepreneur the venture s industry the stage of financing and product development ratings of the venture on 23 characteristics an assessment of the potential return and perceived risk and the decision vis i vis whether to invest the modal venture represented in the database was a start up in the electronics industry with a production capability in place and seeking 1 million median in outside financing there is a high degree of cross referrals between venture capitalists particularly for the purposes of locating co investors factor analysis reduced the 23 characteristics of the deal to five underlying dimensions namely 1 market attractiveness size growth and access to customers 2 product differentiation uniqueness patents technical edge profit margin 3 managerial capabilities skills in marketing management finance and the references of the entrepreneur 4 environmental threat resistance technology life cycle barriers to competitive entry insensitivity to business cycles and down side risk protection 5 cash out potential future opportunities to realize capital gains by merger acquisition or public offering the results of regression analyses showed expected return to be determined by market attractiveness and product differentiation r2 0 22 perceived risk is determined by managerial capabilities and environmental threat resistance r2 0 33 finally a discriminant analysis correctly predicted in 89 4 of the cases whether or not a venture capitalist was willing to commit funds to the deal on the basis of the expected return and perceived risk the reactions of seven venture capitalists who reviewed the model s specification were used to test its validity

is it the weather comment this comment discusses some errors in a recent paper by jacobsen and marquering jacobsen b marquering w 2008 is it the weather journal of banking and finance 32 4 526 540 in which the authors challenge our previous finding that stock market returns exhibit seasonal patterns consistent with the influence of seasonal affective disorder on investor risk aversion we find that we cannot replicate the authors findings even after corresponding with them furthermore we document several problems with their methodology including misspecification of their economic model misspecification of their econometric model and use of inappropriate data while we agree that seasonal affective disorder is not an explanation for all variation in equity markets we do maintain that careful analysis leads to economically and statistically significant evidence of the effect we originally documented

the sampling error in estimates of mean variance efficient portfolio weights this paper presents an exact finite sample statistical procedure for testing hypotheses about the weights of mean variance efficient portfolios the estimation and inference procedures on efficient portfolio weights are performed in the same way as for the coefficients in an ols regression ols t and f statistics can be used for tests on efficient weights and when returns are multivariate normal these statistics have exact t and f distributions in a finite sample using 20 years of data on 11 country stock indexes we find that the sampling error in estimates of the weights of a global efficient portfolio is large

exploitable predictable irrationality the fifa world cup effect on the u s stock market in a recently published paper edmans garcia and norli 2007 reveal a strong association between results of soccer games and local stock returns inspired by their work we propose a novel approach to exploit this effect on the aggregate international level with the following three unique features i the aggregate effect does not depend on the games results hence the effect is an exploitable predictable effect ii the aggregate effect is based on many games hence it is very large and highly significant we find that the average return on the u s market over the world cup s effect period is 2 58 compared to 1 21 for all days average returns over the same period length iii exploiting the aggregate effect is involved with trading in a single index for a relatively long period

subjective random discounting and intertemporal choice this chapter provides an axiomatic foundation for a particular type of preference shock model called the random discounting representation where a decision maker believes that her discount factors change randomly over time for this purpose we formulate an infinite horizon extension of dekel lipman and rustichini econometrica 69 891 934 2001 and identify the behavior that reduces all subjective uncertainties to those about future discount factors we also show uniqueness of subjective belief about discount factors moreover a behavioral comparison about preference for flexibility characterizes the condition that one s subjective belief second order stochastically dominates the other finally the resulting model is applied to a consumption savings problem

divergence of sentiment and stock market trading this paper introduces the concept of divergence of sentiment to the behavioral finance literature we measure the distance between people with positive and negative sentiment on a daily basis for 20 countries by using data from status updates on facebook the prediction is that a higher divergence of sentiment leads to more diverging views on prospects and risks and thus to more diverging views on the value of a stock in line with this prediction divergence of sentiment is positively related to trading volume we further predict and find a positive relation between divergence of sentiment and stock price volatility the observed relations are stronger when individual investors are more likely to trade we compare the effect of our country specific measures to a global measure of divergence of sentiment we find that the separate effects of country specific and global divergence measures depend on a country s level of market integration

the psychological effect of weather on car purchases when buying durable goods consumers must forecast how much utility they will derive from future consumption including consumption in different states of the world this can be complicated for consumers because making intertemporal evaluations may expose them to a variety of psychological biases such as present bias projection bias and salience effects we investigate whether consumers are affected by such intertemporal biases when they purchase automobiles using data for more than 40 million vehicle transactions we explore the impact of weather on purchasing decisions we find that the choice to purchase a convertible or a four wheel drive is highly dependent on the weather at the time of purchase in a way that is inconsistent with classical utility theory we consider a range of rational explanations for the empirical effects we find but none can explain fully the effects we estimate we then discuss and explore projection bias and salience as two primary psychological mechanisms that are consistent with our results jel codes d03 d12

validation of the venture evaluation model in korea abstract this article examines the validity of the venture evaluation model in korea by directly comparing the relative importance of evaluation criteria on the funding decision with the relative importance of factors influencing venture s empirical performance specifically we first identify the relative importance of evaluation criteria based on whether a deal is accepted or rejected current evaluation model next we derive the relative importance of those criteria revealed in the empirical performance based on the success failure of ventures that overlap with the deals originally used as accepted cases performance based model finally to better understand the differences between the two models we measure the general perceptions of venture capitalists on the importance of those criteria without regard to specific deals normative model to identify potentially important criteria we reviewed the existing related studies on evaluation criteria and we interviewed 10 venture capitalists as a result we selected 31 evaluation items the questionnaire consists of two parts and deals with the following four cases in part a 1 1 case 1 general perceptions concerning the 31 criteria in part b 2 2 case 2 one of the most successful ventures 3 3 case 3 one of the least successful ventures 4 4 case 4 one of the rejected ventures using a five point scale we asked the respondents to rate the 31 criteria based on their general perceptions without referring deals case 1 and on the specific deals they had handled cases 2 3 and 4 to prevent any firm or respondent from affecting the results more than it ought to we distributed the questionnaire to each firm in proportion to the investment amounts we also asked the respondents to fill out only one questionnaire including four cases seventy four venture capitalists including 10 interviewed responded to this questionnaire they have worked as investment directors or managers in the top rated 20 venture capital companies selected according to investment amounts on the basis of the ratings of 31 criteria for the previous four cases we developed three investment models first the current evaluation model reveals which criteria are more important in deciding whether or not to fund the model measures the relative importance of evaluation factors in discriminating between the accept case 2 and case 3 and the reject case 4 decision second the performance based model consists of the relative weights of evaluation factors influencing the two performance categories success case 2 and failure case 3 this model shows the relative importance of evaluation criteria that are reflected in the venture s empirical performance finally we identify the normative model revealing the venture capitalists general perceptions concerning the importance of individual criteria in light of their past field experiences case 1 by comparing the three models we find that the importance of these criteria revealed from venture capitalists perceptions and empirical performances is fairly similar but not sufficiently reflected in the actual deal evaluation in particular the entrepreneur related characteristics are not considered the most important in evaluating venture proposals according to the current evaluation model but they do turn out to be the most important factors in evaluating empirical performance this is in strong contrast to the findings of some existing studies which contend that the entrepreneurrelated criteria ultimately determine the funding decision instead the result confirms the previous assertion that the evaluation of managerial capability is the most challenging task in the venture selection process in the current evaluation model financing ability is considered more important than either superiority of product and technology or production capability contrary to venture capitalists perceptions and empirical performance results therefore it seems necessary to raise the level of specialization of venture capital firms through the acquisition of managerial skills from developed countries and by enhancing the technical background of individual venture capitalists

analysis of perfonnance standards for direct foreign investments within the framework of a duopolistic model we investigate the impact of foreign investment standards on welfare output and employment minimum local content and export requirements reduce world output world welfare and the source country s welfare under certain conditions the decline in host country s consumer surplus resulting from diminished competition outweighs the shift of monopoly rent from the source country s firm to the host country s firm minimum content standards can increase host country s employment but only to a point marginal increases in the content requirement can actually reduce employment as the magnitude of foreign investment declines

singapore venture capitalists vcs investment evaluation criteria a reexamination the venture capital vc industry in singapore is of recent origin however funds under management in singapore have grown from s 45 million in 1983 to s 7 86 billion in 1996 these developments together with the recent announcement of government s vision of singapore becoming a hub for venture capital in the region provide an opportunity for an examination of the venture capital industry in singapore the vc industry originated in the western hemisphere in response to the need for risk capital for high technology industries in the light of the differences in investment opportunities around singapore and the nature of industrial developments in south east asia in general the authors anticipated that the investment criteria employed by venture capital firms vcs in singapore would differ the results however reveal that criteria adopted by singapore vcs are not very different from those adopted by vcs in other countries including u s the results also confirm that the entrepreneur s characteristics or the top management s capabilities are seen as being primary indicators of the venture s potential further examination of vcs investment process revealed that the investment criteria adopted by successful vcs were no different from those adopted by less successful vcs this confirms that investment selection is a multi stage process wherein venture assessment is only one of the steps in this process before vcs evaluate a venture they screen investment proposals based on their investment preferences or investment strategies vcs in our sample had definite ideas about where to invest and in what types of firms how do vcs select appropriate investment strategies however has not been adequately dealt in the literature and is a fitting subject for further studies

stock return comovement around the dow jones islamic market world index revisions we examine patterns of comovement in stock returns around the dow jones islamic market world index djimwi quarterly revision events our analysis is based on a sample of 8250 companies from eighteen countries during the period may 1999 june 2012 we find that a stock s comovement with the djimwi increases when it joins and decreases when it leaves the index we also find that the comovement of newly added deleted stocks with the existing djimwi constituents increases declines during periods of high trading activity and during the month of ramadan further tests reveal that changes in the fundamentals have no impact on the comovements of added and deleted stocks overall our results indicate that stock returns respond to the emotional state of investors around information free events

the role of venture capital in financing small business abstract venture capital is a primary and unique source of funding for small firms because these firms with sales and or assets under 5 million have very limited access to traditional capital markets venture capital is a substitute but not a perfect substitute for trade credit bank credit and other forms of financing for small firms small businesses are not likely to be successful in attracting venture capital unless the firms have the potential to provide extraordinary returns to the venture capitalist this study provides an analysis of a survey of venture capital firms that participate in small business financing the survey participants are venture capital firms that were 1986 members of the national venture capital association nvca the largest venture capital association in the united states the average size of the venture capital firms responding to the survey is 92 million dollars in assets with a range from 600 thousand to 500 million twenty three percent of the respondents have total assets below 20 million and 27 have assets above 100 million the venture capitalists investment assets held in small firms delineate the supply of venture capital to small firms sixty three of the 92 venture capitalists have more than 70 of their assets invested in small firms the venture capitalists were asked how their investment plans might change with changes in the tax law that were projected in the spring of 1986 fifty four percent expected to increase their investments in small firms and 38 did not expect to change these activities venture capitalists are very selective in allocating their resources the average number of annual requests that a venture capitalist receives is 652 and the median number is 500 only 11 5 of the respondents receive more than 1 000 proposals per year

mood betas and seasonalities in stock returns abstract existing research has found cross sectional seasonality of stock returns the periodic outperformance of certain stocks during the same calendar months or weekdays we hypothesize that assets different sensitivities to investor mood explain these effects and imply other seasonalities consistent with our hypotheses relative performance across individual stocks or portfolios during past high or low mood months and weekdays tends to recur in periods with congruent mood and reverse in periods with noncongruent mood furthermore assets with higher sensitivities to aggregate mood higher mood betas subsequently earn higher returns during ascending mood periods and earn lower returns during descending mood periods

expropriation of multinational firms the role of domestic market conditions and domestic rivalries expropriation of multinational firms the role of domestic market conditions and domestic rivalries hamid mohtadi the causes of expropriation of multinational firms mnfs by their host governments are investigated based on social welfare analysis and also on public choice theory a key feature is the presence of cournot nash rivalry with domestic firms thus the likelihood of expropriation differs according to whether or not a domestic rival exists the likelihood also depends on the mnf s initial technological superiority over domestic technology the host country s demand structure the type of control to be exercised over the expopriated firm private vs state and the strategic behavior of the mnf ex anti when threat of expropriation i introduction evidence over the past thirty years points to widespread expropriation of multinational firms mnfs particularly by the less developed countries ldcs 1 yet expropriation has received far less attention than impediments to commodity trade tariffs quotas etc one exception is eaton and gersovitz 1984 eg who focus primarily on the impact of an expropriation threat on international capital mobility and the response of foreign capital to such a threat however even allowing for a strategic response to a threat of expropriation the issue of why governments engage in the actual expropriation of existing firms deserves attention 2 explaining expropriation of mnfs already in the host country is the task of this paper while the host government s motives for expropriation may vary as suggested by akinsanya 1980 this paper shall focus on economic motives based on social welfare analysis and on political economic motives based on public choice lobbying theory a key feature will be an emphasis on domestic vs foreign firm rivalry captured by a cournot nash duopoly mode which is aimed at highlighting the potential conflict of interest between the two firms and its effects on the host government s expropriation decision 3 to highlight the role of rivalry section 3 a simple monopoly model of expropriation will be developed in section 2 a second key feature will be to distinguish between the host government s expropriation and ownership decisions regarding the expropriated firm since chances of expropriation may depend on how the ownership issue is settled two cases will be distinguished a the expropriated firm is turned over to domestic residents and the firm continues to maximize profits sections 2 and 3 and b the state controls the expropriated firm i e nationalizes it section 4 4 in this case the government is likely to pursue an objective different from profit maximization see aharoni 1986 ch 4 following caves 1982 chs 1 7 the mnf will be assumed to possess technology superior to that domestically available because of access to intangible assets organizational and managerial know how specific technical knowledge etc not available to domestic firms 5 unlike physical capital intangible assets may be withdrawn in the event of an expropriation threat as in eg s model or actual expropriation as in the present model resulting in increased production costs to the expropriated firm 6 in this paper expropriation in the monopoly model will be motivated by the host country s desire to capture mnf profits otherwise repatriated to increase welfare but this welfare gain may be offset by a loss to consumers via the impact on costs and prices of the mnf s withdrawal of its technology under state ownership some of these results will be altered in the duopoly model the cost increase to the expropriated firm will raise the domestic rival s profits providing it with an incentive to lobby for expropriation this raises the opportunity cost of not lobbying and thus the incentive to lobby by other competing groups mnfs and consumers suggesting that expropriation may be the outcome of lobbying forces rather than of pure welfare considerations

people on the verge of death evidence from impacts of celebrity suicides we attempt to identify the population who are vulnerable to emotional shocks by exploiting an unprecedented series of celebrity suicides in south korea during the last decade including one of the most famous actresses as well as a former president our conservative estimates show that for 5 out of 11 celebrity suicides observed 1 celebrity suicide on average yielded to more than 10 excessive suicides per day over a time frame of at least 2 weeks the results indicate that a significant number of people are very much mentally unstable to end their life by emotional shocks that should be irrelevant to their economic status

tariffs quotas and domestic content protection some political economy considerations in this paper we have focused our attention on the relation between the configuration of protection seeking and of rent seeking interests and the choice of the protection instruments in doing so we have abstracted from the problem of nonequivalence of tariffs and quotas recent writings on product differentiation rodriguez 1979 donnenfeld 1984 have thrown new light on this old issue it may well be that the discussion is of key importance to the understanding of industry s predilection for quantitative restraints we also failed to deal with the question on nonequivalence of restrictive measures under conditions of uncertainty finally we touched only peripherally on the interaction among state it is perhaps more realistic to regard trade barrier formation as a game among nations as in baldwin and clarke 1985 every player seeks at once to protect its import substituting industries and to promote its exports by putting up barriers and by demanding that others lower theirs this approach is more suited however to explain the severity of restraints than it is to explain the nature of restraints which is the problem at hand trade restrictions have a protective and a revenue effect in less developed countries with ineffectual internal revenue collecting systems revenue seeking governments may ally themselves with protection seeking emergent industries and institute high tariffs tariffs and quotas may coexist if the trade restriction seeking alliance includes traders voluntary export restraints the newest of the protective devices may be popular because they circumvent international treaties and short circuit cumbersome procedures associated with changes in tariffs or quotas but they also have the virtue of inviting foreign exporters to act like price setters the harm to the foreign exporters is thereby mitigated in fact exporters may be gainers hence the danger of retaliatory action on the part of foreign governments is lessened domestic content legislation is a unique device in that the same domestic factor benefits from protection and also collects the protection created revenue we show the formal identity between the south african situation in which the maximum black white worker ratio is a binding constraint and regulations requiring that a given percentage of the value of the product be domestically produced we also derive formally the maximum permissible foreign content ratio which is optimal from the point of view of the protected interests in our analysis we have said virtually nothing about the victims of protectionism a discussion of the impact of the various measures on those who bear the cost of protection would doubtless deepen our understanding of the problem we should thus consider the magnitude of the deadweight loss and of the income transfer and the concentration or dispersion of the losers last but not least we should consider the question of awareness thus the cost impact of a tariff is easier to perceive than that of a quota with the cost of a ver or of domestic import content rule the most difficult to calculate of all it may be that the principle of the hiding hand is as important to the new political economy as the benthamite principles were to the old

mood fluctuations projection bias and volatility of equity prices this paper focuses on the potential e2ects of small uctuations in investors subjective preferences speci5cally their discount factors and attitudes towards risk on the volatility of equity prices we brie y summarize some of the arguments and evidence regarding the uctuations in subjective preferences our analysis indicates that such uctuations may have signi5cant implications for understanding the volatility of the prices of 5nancial assets we derive a closed form expression for equilibrium equity prices and use this expression to map the uctuations in investors subjective preferences to the uctuations in equity prices our analysis suggests that small uctuations in the discount factor have potentially large e2ects on the latter for example if the standard deviation of the uctuations in the discount factor is of the order of 1 10th of one percent then this by itself can induce a 3 4 standard deviation in the uctuations in equity prices the uctuations in the attitude towards risk have a smaller but nevertheless non negligible e2ect we present the intuition underlying our conclusions c 2002 published by elsevier science b v

here comes the rain again weather and the intertemporal substitution of leisure i revisit the intertemporal labor supply framework using exogenous variations in daily weather to see how time at work varies with rain in my model a rainy day is associated with a lower enjoyment of leisure effectively increasing wages and bringing more hours at work i test the model using data from the american time use survey supplemented with daily weather i find that on rainy days men shift on average 30 minutes from leisure to work computations give a rough estimate of the intertemporal elasticity of labor supply of around 0 01 in line with the rest of the literature

the impact of climate risk on firm performance and financing choices an international comparison increasingly adverse climatic conditions have created greater systematic risk for companies throughout the global economy few studies have directly examined the consequences of climate related risk on financing choices by publicly listed firms across the globe we attempt to do so using the global climate risk index compiled and published by germanwatch kreft eckstein 2014 which captures at the country level the extent of losses from extreme weather events as expected we find the likelihood of loss from major storms flooding heat waves etc to be associated with lower and more volatile earnings and cash flows consistent with policies that attempt to moderate such effects we show that firms located in countries characterized by more severe weather are likelier to hold more cash so as to build financial slack and thereby organizational resilience to climatic threats those firms also tend to have less short term debt but more long term debt and to be less likely to distribute cash dividends in addition we find that certain industries are less vulnerable to extreme weather and so face less climate related risk our results are robust to using an instrumental variable approach a propensity score matched sample and path analysis and remain unchanged when we consider an alternative measure of climate risk finally our conclusions are invariant to the timing of financial crises that can affect different countries at different times

venture capitalists decision policies across three countries an institutional theory perspective this paper examines the influence of economic institutions upon venture capitalists vcs decision policies we conducted policy capturing experiments on 119 vcs across three countries representing distinct economic institutions us mature market economy south korea emerging economy and china transitional economy results show that vcs in rules based market economies us rely upon market information to a greater extent than vcs in emerging economies korea and chinese vcs transitional economy weight human capital factors more heavily than either us or korean vcs findings suggest that although professional institutions may dictate which information is included in vc decision policies the extent to which that information is emphasized is determined partly by the economic institution in which the decision maker operates journal of international business studies 2007 38 691 708 doi 10 1057 palgrave jibs 8400291

bayesian herders updating of rainfall beliefs in response to external forecasts summary temporal climate risk weighs heavily on many of the world s poor model based climate forecasts could benefit such populations provided recipients use forecast information to update climate expectations we test whether pastoralists in southern ethiopia and northern kenya update their expectations in response to forecast information the minority of herders who received these climate forecasts updated their expectations for below normal rainfall but not for above normal rainfall this revealed preoccupation with downside risk highlights the potential value of better climate forecasts in averting drought related losses but realizing any welfare gains requires that recipients strategically react to these updated expectations

happiness and time preference the effect of positive affect in a random assignment experiment abstract we conduct a random assignment experiment to investigate whether positive affect impacts time preference where time preference denotes a preference for present over future utility our result indicates that compared to neutral affect mild positive affect significantly reduces time preference over money this result is robust to various specification checks and alternative interpretations of the result are considered our result has implications for the effect of happiness on time preference and the role of emotions in economic decision making in general finally we reconfirm the ubiquity of time preference and start to explore its determinants djel d12 d83 i31

losing sleep at the market the daylight saving anomaly reply motivated by the recent flurry of activity in sleep research this paper explores the connection between sleep disruptions following spring and fall clock shifts associated with daylight savings time and equity returns it is shown that the weekend effect in the form of the lower than expected friday to monday returns is particularly pronounced for the two weekends involving daylight savings clock changes this abstract was borrowed from another version of this item

do markets respond more to more reliable labor market data a test of market rationality since 1979 the bureau of labor statistics bls has nearly quadrupled the size of the sample used to estimate monthly employment changes although first reported employment estimates are still noisy the magnitude of sampling variability has declined in proportion to the increase in the sample size a model of rational bayesian updating predicts that investors would assign more weight to the bls employment survey as it became more precise however a regression analysis of changes in interest rates on the day the employment data are released finds no evidence that the bond market s reaction to employment news intensified in the late 1980s or early 1990s for the time period as a whole an unexpected increase of 200 000 jobs is associated with an 8 basis point increase in the interest rate on 30 year treasury bonds and a 9 basis point increase in the interest rate on 3 month bills all else equal additionally announced hourly wage increases are associated with higher long tern interest rates while announced changes in the unemployment rate and revisions to past months employment estimates have a statistically insignificant effect on long term interest rates
