can the stock market success of montreal s ipos be predicted by the prospectus content in this paper we investigated if it is possible for investors to objectively estimate the probability of success of newly public companies using the information contained in offering prospectuses analysing prospectuses of small firms that went public on the montreal stock exchange revealed that the age of the firm at the time of the ipo the percentage of voting rights sold by managers the sales growth potential and the subscription price of newly quoted firms could be good predictors of long term performance on the stock market however it is relatively difficult to link any information contained in the issuing prospectus to short term performance the findings of this study should help authorities to define more stringent criteria to accept new public offerings and make the small cap market more attractive to investors and new growing companies

measuring excess capital capacity in agricultural production we introduce the concept excess capital capacity and employ a stochastic input requirement frontier to measure excess capital capacity in agricultural production we also propose a two step estimation method that allows endogenous regressors in stochastic frontier models the first step uses generalized method of moments to get consistent estimates of the frontier parameters in the presence of endogenous regressors the second step uses maximum likelihood to measure excess capital capacity and evaluate the factors that influence it the empirical application to dutch cash crop farms found varying degrees of excess capital capacity the policy implications of excess capital capacity are discussed

estimation of production technology when the objective is to maximize return to the outlay abstract this paper deals with estimation of production technology where endogeneous choice of input and output variables is explicitly recognized to address this endogeneity issue we assume that producers maximize return to the outlay we start from a flexible translog transformation function with a single output and multiple inputs and show how the first order conditions of maximizing return to the outlay can be used to come up with an estimating equation that does not suffer from the econometric endogeneity problem although the output and input variables are chosen endogenously this is because the regressors in this estimating equation are in ratio forms which are uncorrelated with the error term under the assumption that producers maximize return to the outlay the analysis is then extended to the multiple outputs and multiple inputs case with technical inefficiency although the estimating equations in both single and multiple output cases are neither production nor distance functions they can be estimated in a straightforward manner using the standard stochastic frontier technique without worrying about endogeneity of the regressors thus we provide a rationale for estimating the technology parameters consistently using an econometric model which requires data on only input and output quantities

hedging the black swan conditional heteroskedasticity and tail dependence in s p500 and vix the recent financial crisis has accentuated the fact that extreme outcomes have been overlooked and not dealt with adequately while extreme value theories have existed for a long time the multivariate variant is difficult to handle in the financial markets due to the prevalent heteroskedasticity embedded in most financial time series and the complex extremal dependence that cannot be conveniently captured by a single structure moreover most of the existing approaches are based on a limiting argument in which all variables become large at the same rate in this paper we show how the conditional approach of heffernan and tawn 2004 can be implemented to model extremal dependence between financial time series we use a hedging example based on vix futures to demonstrate the flexibility and superiority of the conditional approach against the conventional ols regression approach

are policy platforms capitalized into equity prices evidence from the bush gore 2000 presidential election abstract this paper tests for the capitalization of policy platforms into equity prices using a sample of 70 firms favored under bush or gore platforms during the 2000 u s presidential election two sources of daily data during the six months leading up to the election are incorporated firm specific equity returns and the probability of a bush victory as implied by prices from the iowa electronic market for this group of politically sensitive firms the daily baseline estimates demonstrate that platforms are capitalized into equity prices under a bush administration relative to a counterfactual gore administration bush favored firms are worth 3 more and gore favored firms are worth 6 less implying a statistically significant differential return of 9 estimates based on weekly returns are even stronger suggesting a differential return of 16 the most sensitive sectors include tobacco worth 13 more under a favorable bush administration microsoft competitors worth 15 less under an unfavorable bush administration and alternative energy companies worth 16 less under an unfavorable bush administration a corresponding analysis of campaign contributions which allows for heterogeneity in the importance of policy platforms to the firms supports the baseline estimates

unleashing animal spirits self control and overpricing in experimental asset markets one explanation for overpricing on asset markets is a lack of traders self control we implement the first experiment to address the causal relationship between self control and systematic overpricing on financial markets our setup detects some of the channels through which low individual self control could transmit into irrational exuberance in markets our data indicate a large direct effect of reduced self control on market overpricing low self control traders report stronger emotions after the market

thar she bursts reducing confusion reduces bubbles to explore why bubbles frequently emerge in the experimental asset market model of smith suchanek and williams 1988 we vary the fundamental value process constant or declining and the cash to asset value ratio constant or increasing we observe high mispricing in treatments with a declining fundamental value while overvaluation emerges when coupled with an increasing c a ratio a questionnaire reveals that the declining fundamental value process confuses subjects as they expect the fundamental value to stay constant running the experiment with a different context stocks of a depletable gold mine instead of stocks significantly reduces mispricing and overvaluation as it reduces confusion jel c91 d14 g11 g12

price movements and price discovery in futures and cash markets r isk transfer and price discovery are two of the major contributions of futures markets to the organization of economic activity working 1962 evans 1978 p 80 and silber 1981 risk transfer refers to hedgers using futures contracts to shift price risk to others price discovery refers to the use of futures prices for pricing cash market transactions working 1948 wiese 1978 p 87 and lake 1978 p 161 the significance of both contributions depends upon a close relationship between the prices of futures contracts and cash commodities this paper examines the characteristics of price movements in cash or spot markets and futures markets for storable commodities section ii presents an analytical model of simultaneous price dynamics which suggests that over short intervals of time the correlation of price changes is a function of the elasticity of arbitrage between the physical commodity and its counterpart futures contract greater elasticity fosters more highly correlated price changes and thereby facilitates the risk transfer function the elasticity of supply of arbitrage services is constrained by among other things storage and transaction costs thus futures contracts will not in general provide perfect risk transfer facilities over short time horizons the essence of the price discovery function of futures markets hinges on whether new information is reflected first in changed futures prices or in changed cash prices hoffman 1932 pp 258259 the model in section ii provides a framework for analyzing whether one market is dominant in terms of information flows and price discovery in section iii we develop a model based on section ii which is appropriate for estimating the lead lag relationship between cash prices and futures prices section iv presents empirical estimates of the parameters of the model for seven different storable commodities wheat corn oats frozen orange juice concentrates copper gold and silver the cost of arbitrage between cash and futures differs across these commodities for this reason we are not surprised to find inter commodity differences in the correlation of short run price changes and in the substitutability of futures contracts for cash market positions with respect to the price discovery function of futures markets we find that while futures markets dominate cash markets cash prices do not merely echo futures prices there are reverse information flows from cash markets to futures markets as well

macroeconomic policy in a two party system as a repeated game this paper considers the interaction of two parties with different objectives concerning inflation and unemployment and rational and forward looking wage setters if discretionary policies are followed an economic cycle related to the political cycle results in equilibrium this cycle is significantly different from the traditional political business cycle reputational mechanisms due to the repeated interaction of the two parties and the public or commitments to a common policy rule can improve upon the discretionary outcome by reducing or eliminating the magnitude of the economic fluctuations

relative performance of public and private ownership under yardstick competition electricity retail distribution abstract this paper focuses on productive efficiency in swedish retail electricity distribution during 1970 1990 using hedonic output s constructed from physical outputs and their qualities and network characteristics the main focus is on efficiency of privately owned municipal utilities municipal companies and companies with mixed ownerships three different approaches are used to examine whether ownership of the distribution companies has any systematic impact on the above issues we also examine returns to scale and technical change empirical results from the three alternative approaches show that privately owned companies are relatively more efficient we find evidence of scale economies and technical progress

bubbles crashes and endogenous expectations in experimental spot asset markets1 spot asset trading is studied in an environment in which all investors receive the same dividend from a known probability distribution at the end of each of t 15 or 30 trading periods fourteen of twenty two experiments exhibit price bubbles followed by crashes relative to intrinsic dividend value when traders are experienced this reduces but does not eliminate the probability of a bubble the regression of changes in mean price on lagged excess bids number of bids minus the number of offers in the previous period p pt a f b 1 o l supports the hypothesis that a e d the one period expected value of the dividend and that f 0 where excess bids is a surrogate measure of excess demand arising from homegrown capital gains losses expectations thus when bt 1 o goes to zero we have convergence to rational expectations in the sense of fama 1970 that arbitrage becomes unprofitable the observed bubble phenomenon can also be interpreted as a form of temporary myopia tirole 1982 from which agents learn that capital gains expectations are only temporarily sustainable ultimately inducing common expectations or priors tirole 1982 four of twenty six experiments all using experienced subjects yield outcomes that appear to the chart s eye to converge early to rational expectations although even in these cases we get 0 and small price fluctuations of a few cents that invite scalping

electoral uncertainty fiscal policy and macroeconomic fluctuations abstract in this paper we study the link between elections fiscal policy and aggregate fluctuations the setup is a stylized dynamic stochastic general equilibrium model incorporating both technology and political re election shocks the latter are incorporated via a two party model with elections the main theoretical prediction is that forward looking incumbents with uncertain prospects of re election find it optimal to follow relatively shortsighted fiscal policies and that this hurts capital accumulation our econometric estimation using u s data finds a statistically significant link between electoral uncertainty and policy instruments and in turn macroeconomic outcomes

school district consolidation market concentration and the scale efficiency tradeoff consolidation is often proposed as a strategy for increasing school district quality without increasing educational funding however if consolidation reduces competition in the local school market and reduces efficiency any savings from exploiting economies of scale may be lost to increased inefficiency we use a stochastic cost function to investigate these effects for districts in texas we find important economies of scale but we also find that increased market concentration leads to increased cost inefficiency finally we illustrate the practical importance of these two potentially offsetting factors in a simulation that considers consolidating texas school districts to county level districts we find that failure to consider the effect on competition can lead to large overestimates of the benefits of consolidation

option implied volatility factors and the cross section of market risk premia abstract the main goal of this paper is to study the cross sectional pricing of market volatility the paper proposes that the market return diffusion volatility and jump volatility are fundamental factors that change the investors investment opportunity set based on estimates of diffusion and jump volatility factors using an enriched dataset including s p 500 index returns index options and vix the paper finds negative market prices for volatility factors in the cross section of stock returns the findings are consistent with risk based interpretations of value and size premia and indicate that the value effect is mainly related to the persistent diffusion volatility factor whereas the size effect is associated with both the diffusion volatility factor and the jump volatility factor the paper also finds that the use of market index data alone may yield counter intuitive results

cognitive ability and earnings performance evidence from double auction market experiments abstract our goal in this paper is to understand how heterogeneity in people s cognitive ability leads to different market behavior and thus different market performance to do this subjects with heterogeneous working memory capacity wmc were placed in a double auction environment to compete against artificial traders we considered two treatments which differ in the artificial traders the artificial traders are truth telling in the first treatment but demonstrate adaptive trading behavior in the second one our results show that working memory capacity has a significantly positive effect on subjects market performance and the performance gap caused by cognitive ability while narrowing over time remains significant by the end of experiment we find that differences in subjects performance resulted from their behavior high wmc subjects were better at exploiting extra profit opportunities and avoiding unprofitable transactions and they tended to underbid more than those with lower wmc among the five constituent abilities of wmc we find that it is distinctive abilities which contribute to the overall significance in these two treatments for the treatment involving truth telling traders the relevant factor is the ability of simultaneous processing and storing information whereas for the treatment involving adaptive traders the only one that matters is subjects ability to coordinate elements into structures

price bubbles and crashes in experimental call markets abstract price bubbles relative to intrinsic dividend value are observed using a call market trading institution market prices tend to track intrinsic value only when the same group of highly experienced traders participate in three consecutive 15 round markets

presidential and congressional vote share equations three vote share equations are estimated and analyzed in this paper one for presidential elections one for on term house elections and one for mid term house elections the sample period is 1916 2006 considering the three equations together allows one to test whether the same economic variables affect each and to examine various serial correlation and coattail possibilities the resulting three equation model can then be analyzed dynamically which is done in section 4 the main conclusions are briefly 1 there is strong evidence that the economy affects all three vote shares and in remarkably similar ways 2 there is no evidence of any presidential coattail effects on the on term house elections the presidential vote share and the on term house vote share are highly positively correlated but this is because they are affected by some of the same variables 3 there is positive serial correlation in the house vote in that the previous mid term house vote share positively affects the on term house vote share and the previous on term house vote share positively affects the mid term house vote share 4 the presidential vote share has a negative effect on the next mid term house vote share the most likely explanation for this is a balance argument where voters are reluctant to let one party become too dominant ruled out as possible explanations for this fourth result is any reversal of a coattail effect since there is no evidence of an effect in the first place and a regression to the mean since the positive serial correlation in the house vote implies no such regression also it is not simply voting against the party in the white house because the presidential variable is a vote share variable not a 0 1 incumbency variable

labour use efficiency in swedish social insurance offices this paper considers the estimation of frontier production functions in panel data models it proposes a multi stage method to obtain estimates of 1 the parameters of a flexible input requirement function and 2 technical inefficiency decomposed into time invariant firm specific time varying and the residual components the proposed method is used to analyse labour use efficiency of swedish local social insurance offices on the basis of a large panel of observations during the time period 1974 84 empirical results show 1 substantial variations in labour use efficiency among these offices with the mean efficiencies declining over time 2 presence of economies of scale thereby meaning that most of the offices were of suboptimal size

the multiple unit double auction the note outlines institutional features of an open outcry market that permit multiple unit or block trades the purpose of the note is to introduce the process as a tool to be used in economics experiments the detailed rules governing the multiple unit double auction muda are stated for the case where offers are tendered by voice as opposed to through a computer the results of markets that use the rules are reported as a demonstration that convergence to equilibrium price traditionally observed in experimental markets remains with the use of the muda process

the high frequency trade off between speed and sophistication abstract central to the ability of a high frequency trader to make money is speed in order to be first to trading opportunities firms invest in the fastest hardware and the shortest connections between their machines and the markets yet this is not enough algorithms must be short no more than a few instructions as a result there is a trade off in the design of optimal high frequency trading strategies being the fastest necessitates being less sophisticated to understand the effect of this tension a computational model is presented that captures latency both of code execution and information transmission trading algorithms are modelled through genetic programming with longer programmes allowing more sophisticated decisions at the cost of slower execution times it is shown that depending on the market composition short fast strategies and slower more sophisticated strategies may both be viable and exploit different trading opportunities the relative profits of these different approaches vary however slow traders benefit and social welfare increase in the presence of hfts a suite of regulations are tested to manage the risks associated with high frequency trading the majority are found to be ineffective though constraining the ratio of orders to trades may be promising

united states investment returns during democratic and republican administrations 1928 1993 a major difference in returns from large capitalization stocks small capitalization stocks various bond indexes and cash followed elections won by democratic and republican presidents from 1928 to 1993 small cap stocks had significantly higher returns during democratic administrations than during republican administrations primarily reflecting a lack of losses in the april december period this phenomenon was not a manifestation of the january small firm effect indeed the results indicate a significant small cap effect outside january during democratic presidencies large cap stocks had statistically identical returns under both administrations for both democratic and republican administrations small and large cap stock returns were significantly higher during the last two years of the presidential term than during the first two years corporate long term government and intermediate government bonds and cash had significantly higher returns during republican administrations from 1937 to 1993

inefficiency and heterogeneity in turkish banking 1990 2000 recent studies have stressed the importance of privatization and openness to foreign competition for bank efficiency and economic growth we study bank efficiency in turkey an emerging economy with great heterogeneity in bank types and ownership structures earlier studies of turkish banking had three limitations i excessive reliance on cost function frontier analyses wherein volume of loans is a measure of banking output ii pooling all banks or imposing ad hoc heterogeneity assumptions and iii lack of a comprehensive panel data set for proper analysis of productivity and heterogeneity we use an estimation classification procedure to find likelihood driven classification of bank technologies in an 11 year panel in addition we augment traditional cost frontier analysis with a labour efficiency analysis we conclude that state banks are not particularly inefficient overall but that they do utilize labour inefficiently this partially supports recent calls for privatization we also conclude that special finance houses or islamic banks utilize the same technology as conventional domestic banks and do so relatively efficiently this suggests that they do not cause harm to the financial system finally we conclude that foreign banks utilize a different technology from domestic ones this suggests that one should not overstate their value to the financial sector copyright 2005 john wiley sons ltd

political risk and market efficiency tests based in british stock and options markets in the 1987 election abstract this paper examines the behaviour of the stock and options markets in london during the 1987 election we find an extremely close relationship between opinion polls and the ftse 100 index of share prices however in the last week of the election the options prices showed evidence of gross inefficiency they implied a decreasing probability of a conservative win while the polls indicated the opposite the inefficiency was sufficiently large for a volatility arbitrage to be feasible net of transactions costs these two tests appear to indicate that a speculative bubble was present in the options

a new view of political accountability for economic performance most political support models imply that in evaluating economic performance voters use a standard that would provide poor predictions of the future and leave the economy vulnerable to manipulation by vote hungry politicians drawing on macroeconomic theory we develop a simple standard of evaluation which encompasses a concern not only for current economic outcomes but also for accurately assessed future consequences of current policies we find that political support for the president can be explained as well by models that assume that voters use this sophisticated standard as by models that assume voter naivete our analysis questions the wisdom of measures typically used to assess voter evaluation of economic performance in a variety of theoretical contexts the results also help to explain the absence of convincing evidence that governments exploit voter ignorance in manipulating the economy

a further analysis of the lead lag relationship between the cash market and stock index futures market the intraday lead lag relation between returns of the major market cash index and returns of the major market index futures and s p 500 futures is investigated empirical results show strong evidence that the futures leads the cash index and weak evidence that the cash index leads the futures the asymmetric lead lag relation holds between the futures and all component stocks including those that trade in almost every five minute interval evidence indicates that when more stocks move together market wide information the futures leads the cash index to a greater degree this suggests that the futures market is the main source of market wide information article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

estimating the potential for electricity savings in households abstract improving efficiency in the use of energy is an important goal for many nations since end use energy efficiency can help to reduce co 2 emissions furthermore since the residential sector in industrialised countries requires around one third of the end use electricity it is important for policy makers to estimate the scope for electricity saving in households to reduce electricity consumption by using appropriate steering mechanisms we estimate the level of technical efficiency in the use of electricity using data from a swiss household survey we find an average inefficiency in electricity use by swiss households of around 20 to 25 bottom up economic engineering models estimate the potential in switzerland to be around 15 in this paper we use a sub vector input distance frontier function based on economic foundations our estimates lie at the upper end of the electricity saving potential estimated by the afore mentioned economic engineering approach

on booms that never bust ambiguity in experimental asset markets with bubbles we study the effect of ambiguity on the formation of bubbles and on the occurrence of crashes in experimental asset markets a la smith suchanek and williams 1988 we extend their framework to an environment where the fundamental value of the asset is ambiguous we show that when the fundamental value is ambiguous asset prices tend to be lower than when it is risky although bubbles form in both the ambiguous and the risky environments additionally bubbles do not crash in the ambiguous case whereas they do so in the risky one these findings regarding depressed prices and the absence of crashes in the presence of ambiguity are in line with recent theoretical work stressing the crucial role of ambiguity to account for surprisingly low equity prices high returns as well as herding in asset markets

nyse sector returns and political cycles we address three issues regarding the relationship between political party affiliation and returns in the equities markets as measured by the nyse composite index and its sub indexes first we find a tendency for returns to be greater during democratic presidential administrations however this result is statistically insignificant second we conclude that returns during the last two years of presidential administrations are greater than during the first two years third we examine the relationship between the majority party in each house of congress and equity returns we raise the possibility that party affiliation of congress is a factor in explaining returns

an adjustment cost rationalization of asset fixity theory this article integrates a classic concept in production economics g l johnson s asset fixity theory with the dynamic adjustment cost model until now the literature has considered these two to be incompatible by relaxing the smoothness assumption of the adjustment cost function at the origin the theory of costs of adjustment can provide a rigorous endogenization of asset fixity g l johnson and edwards results are then obtained when the linearity assumption of the adjustment cost function is imposed the work reported here also indicates that both smoothness at the origin and symmetry of adjustment cost function should be subject to empirical tests

futures trading information and spot price volatility evidence for the ftse 100 stock index futures contract using garch abstract this paper examines the impact of trading in the ftse 100 stock index futures on the volatility of the underlying spot market to examine the relationship between information and volatility as subject neglected in previous studies the garch family of techniques is used the results suggest that futures trading has led to increased volatility but that the nature of volatility has not changed post futures the finding of price changes being integrated pre futures but being stationary post futures implies that the introduction of futures has improved the speed and quality of information flowing to the spot market

us presidential elections and implied volatility the role of political uncertainty abstract this paper focuses on the effects of political uncertainty and the political process on implied stock market volatility during us presidential election cycles using monthly iowa electronic markets data over five elections we document that stock market uncertainty as measured by the vix volatility index increases along with positive changes in the probability of success of the eventual winner the association between implied volatility and the election probability of the eventual winner is positive even after controlling for changes in overall election uncertainty these findings indicate that the presidential election process engenders market anxiety as investors form and revise their expectations regarding future macroeconomic policy

bubbles and financial professionals the efficiency of financial markets and their potential to produce bubbles are central topics in academic and professional debates yet little is known about the contribution of financial professionals to price efficiency we run 116 experimental markets with 412 professionals and 502 students we find that professional markets with bubble drivers capital inflows or high initial capital supply are susceptible to bubbles although they are more efficient than student markets in mixed markets with students bubbles also occur but professionals act as price stabilizers we show that heterogeneous price beliefs drive overpricing especially in bubble prone market environments

how markets process information news releases and volatility we examine the impact of scheduled macroeconomic news announcements on interest rate and foreign exchange futures markets we find these announcements are responsible for most of the observed time of day and day of the week volatility patterns in these markets while the bulk of the price adjustment to a major announcement occurs within the first minute volatility remains substantially higher than normal for roughly fifteen minutes and slightly elevated for several hours nonetheless these subsequent price adjustments are basically independent of the first minute s return we identify those announcements with the greatest impact on these markets we examine the impact on interest rate and foreign exchange markets of scheduled macroeconomic news releases such as the employment report the consumer price index cpi and the producer price index ppi many market participants believe that such announcements have a major impact on financial markets indeed a small industry devoted to predicting the figures to be released in upcoming releases has evolved in recent years with the exception of the weekly money supply figures however the impact of such announcements on financial markets has received scant attention 1 this is doubly surprising given the considerable research interest in market volatility since these news releases are a potential source of much of this volatility consider for instance figure 1 as shown there prices in interest rate and foreign exchange futures markets are much more volatile between 8 30 and 8 35 a m eastern time et than during any other five minute trading period including

risk aversion uncertain information and market efficiency abstract this paper develops and tests the uncertain information hypothesis as a means of explaining the response of rational risk averse investors to the arrival of unanticipated information the theory predicts that following news of a dramatic financial event both the risk and expected return of the affected companies increase systematically and that prices react more strongly to bad news than good an empirical investigation of over 9000 marketwide and firm specific events produces results consistent with these predictions we conclude that the market reacts to uncertain information in an efficient if not instantaneous manner

us presidential elections and real gdp growth 1961 2004 in this paper i show that since 1960 an electoral cycle in us output growth can both be seen by the naked eye in the raw data and confirmed by a statistical analysis that allows for rational partisan effects as well as a wide range of control variables that is controlling for multiple lags of interest rate changes inflation money growth energy prices lagged output growth government spending or its growth and temporary partisan effects the timing of elections exerts a significant influence on quarterly real gdp growth

integrating agronomic principles into production function specification a dichotomy of growth inputs and facilitating inputs this article presents a general conceptual framework for integrating agronomic principles into economic production analysis we categorize inputs in crop production into growth inputs and facilitating inputs based on this dichotomy we specify an asymmetric production function the robustness of the asymmetric framework is tested using crop level panel data on potato production in the netherlands the test results do not reject the proposed framework and the asymmetric specification better represents the underlying production technology

the effect of short selling and borrowing on market prices and traders behavior this paper studies the influence of allowing borrowing and short selling on market prices and traders forecasts in an experimental asset market we verify although not statistically significantly so that borrowing tends to increase asset overvaluation and price orecasts while short selling tends to reduce these measures we also show that a number of results on beliefs traders types cognitive sophistication and earnings obtained in earlier experimental studies in which borrowing and short selling are not possible generalize to markets with borrowing and short sales

the effect of short selling on bubbles and crashes in experimental spot asset markets a series of experiments illustrate that relaxing short selling constraints lowers prices in experimental asset markets but does not induce prices to track fundamentals we argue that prices in experimental asset markets are influenced by restrictions on short selling capacity and limits on the cash available for purchases restrictions on short sales in the form of cash reserve requirements and quantity limits on short positions behave in a similar manner a simulation model based on delong et al 1990 generates average price patterns that are similar to the observed data asset market bubbles are persistent deviations of prices from fundamentals to the extent that bubbles exist they can influence investment levels and the allocation of capital and thereby have considerable economic effects in recognition of their potential importance the question of the existence and pervasiveness of bubbles has been a focus of extensive empirical investigation see e g shiller 1981 blanchard and watson 1982 diba and grossman 1988 and west 1988 these studies yield mixed results regarding the empirical relevance of bubble phenomena one source of the differences in conclusions may be that because the fundamental value of the assets cannot be observed tests of the presence of bubbles are joint tests with the particular specification of the process guiding the evolution of fundamentals also being tested the availability of short selling is widely believed to make bubble formation less likely one rationale for such a belief is the notion that the cause of asset market bubbles is a constraint on the ability of traders to speculate on future downward price movements see e g miller 1977 jarrow 1980 diamond and verrecchia 1987 or figlewski and webb 1993 in the absence of short sales traders may sell only the shares in their portfolios the availability of short sales relaxes this constraint in this paper we study empirically the effect of allowing short sales on both the incidence and magnitude of market bubbles we choose a setting in which the fundamental value of the asset is clearly and unambiguously defined and known at all times and bubbles typically occur namely we use the experimental environment that smith suchanek and williams 1988 introduce while

the jeffords effect abstract in may 2001 senator james jeffords left the republican party and tipped control of the u s senate to the democrats this paper uses the surprise event to demonstrate what i term the jeffords effect changes in the political landscape have large effects on the market value of firms i use a firm s soft money donations to the national parties as the measure of how the firm aligns itself politically in this event study a firm lost 8 percent of market capitalization the week of jeffords s switch for every 250 000 it gave to the republicans in the previous election cycle on the basis of the point estimates the stock price gain associated with democratic donations is smaller than the loss associated with republican donations but the estimates are consistent with the effects being equal and opposite the results withstand several robustness checks and the effects appear to persist over time

the informational efficiency of experimental asset markets a fundamental difficulty in devising any test of general efficient market hypotheses is the specification of the relevant public and private information sets of traders without a consensus as to reasonable empirical specifications tests of the hypotheses remain minimal or controversial in this study we examine the efficiency of experimental asset markets in which one may unambiguously identify the public and private information sets of traders we focus on how market efficiency is affected by the presence of futures markets in settings that incorporate different types of uncertainty and inside information our experimental results support four conclusions 1 market outcomes tend to evolve toward strong form informationally efficient equilibria whether or not futures markets and or event uncertainty are present 2 the presence of futures markets clearly stabilizes spot prices 3 the presence of futures markets tends to speed the evolution of asset markets to more efficient equilibria where there

nonspeculative bubbles in experimental asset markets lack of common knowledge of rationality vs actual irrationality we report the results of an experiment designed to study the role of speculation in the formation of bubbles and crashes in laboratory asset markets in a setting in which speculation is not possible bubbles and crashes are observed the results suggest that the departures from fundamental values are not caused by the lack of common knowledge of rationality leading to speculation but rather by behavior that itself exhibits elements of irrationality much of the trading activity that accompanies bubble formation in markets where speculation is possible is due to the fact that there is no other activity available for participants in the experiment

political parties and the business cycle in the united states 1948 1984 this paper tests the existence and the extent of a politically induced business cycle in the u s in the post world war ii period the cycle described in this paper is different from the traditional political business cycle of nordhaus it is based on a systematic difference between the monetary policies of the two parties in a model with labor contracts from an explicit optimization problem we derive a system of equations for output and money growth then we successfully test the non linear restriction imposed by the theory on the parameters of the system of equations we cannot reject the hypothesis that money growth has been systematically different under the two types of administration and that this difference contributes to explain output fluctuations

measuring financial asset return and volatility spillovers with application to global equity markets we provide a simple and intuitive measure of interdependence of asset returns and or volatilities in particular we formulate and examine precise and separate measures of return spillovers and volatility spillovers our framework facilitates study of both non crisis and crisis episodes including trends and bursts in spillovers and both turn out to be empirically important in particular in an analysis of sixteen global equity markets from the early 1990s to the present we find striking evidence of divergent behavior in the dynamics of return spillovers vs volatility spillovers return spillovers display a gently increasing trend but no bursts whereas volatility spillovers display no trend but clear bursts

asymmetric adjustment of dynamic factors at the firm level presents a study which addressed the deficiencies of previous studies the specification and estimation in the modeling of asymmetry and zero gross investment in the agricultural industry reference to previous studies on asymmetry information on the standard dual model results of the study

government policy and agricultural productivity in indonesia we focus on the agricultural productivity implications of the complex of investment price and research policies the indonesian government has employed since the end of the green revolution in particular we employ a new 1985 2005 provincial panel dataset together with a stochastic output distance frontier framework to examine how government policies have affected the nation s agricultural productivity decomposing it into its technical progress and efficiency components government s primary contributions to technology growth have come through price and trade policies rather than public research most technology growth however appears to be due to informal technology diffusion copyright 2010 oxford university press

futures contracting and dividend uncertainty in experimental asset markets prices in experimental asset markets tend to bubble and then crash to dividend value at the end of the asset s useful life explanations for this phenomenon are 1 that participants cannot form reliable future price expectations or 2 dividend risk aversion we report the results of experiments to test these hypotheses in one experimental series a futures market is introduced so that participants can obtain information on future share prices in another series of experiments the per period dividend is known with certainty the futures market treatment reduced the bubble the certain dividend treatment had little effect on the character of bubbles with inexperienced traders copyright 1995 by university of chicago press

a distribution free stochastic frontier model with endogenous regressors abstract we provide a guideline for estimating a distribution free panel data stochastic frontier model in the presence of endogenous variables in particular we consider variations of the within estimator of cornwell et al 1990 to allow endogenous regressors

local versus international crises and bank stability does bank foreign expansion make a difference abstractwe investigate the impact of global and local crises on bank stability in the mena region and examine the effect of owning bank subsidiaries in other countries we consider banks that experienced both types of crises during our sample period our findings highlight a negative impact of the global financial crisis of 2007 2008 on bank stability but on the whole no negative impact of the local crisis a deeper investigation shows that owning bank subsidiaries outside the home country is a source of increased fragility during normal times yet a source of higher stability during the local crisis but not during the international crisis moreover owning foreign subsidiaries in one or two world regions is insufficient to neutralize both types of crises while being present in three or more regions is more stabilizing during a local crisis but also more destabilizing during an international crisis our findings contribute to the literature examining bank stability and have several policy implications

price bubbles gender and expectations in experimental asset markets abstract this paper reports results of laboratory markets for a risky asset with a flat fundamental value that equates expected dividends to the return on a safe asset subjects were sorted by gender in an unobtrusive manner and bubbles in this setting are pervasive and of comparable magnitude for both genders in contrast a robustness check done with a declining fundamental value did generate larger bubbles for groups of males elicited price forecasts tend to trail share prices as they rise and exceed prices as they fall a pattern that is tracked by a double adaptive forecasting model

multi output nonfrontier primal measures of capacity and capacity utilization this article implements an econometric approach for generating primal capacity output and utilization measures for fisheries in situations where regulatory environmental and resource conditions affect catch levels but are not independently identified in the data frontier based capacity models may interpret such impacts as production inefficiency however if such inefficiencies are unlikely to be eliminated the implied potential output increases may be unrealistic we develop a multi output multi input stochastic transformation function framework that permits various assumptions about how output composition may change when operating at full capacity we apply our model to catcher processor vessels in the alaskan pollock fishery

measurement of energy efficiency based on economic foundations abstract energy efficiency policy is seen as a very important activity by almost all policy makers in practical energy policy analysis the typical indicator used as a proxy for energy efficiency is energy intensity however this simple indicator is not necessarily an accurate measure given changes in energy intensity are a function of changes in several factors as well as true energy efficiency hence it is difficult to make conclusions for energy policy based upon simple energy intensity measures related to this some published academic papers over the last few years have attempted to use empirical methods to measure the efficient use of energy based on the economic theory of production however these studies do not generally provide a systematic discussion of the theoretical basis nor the possible parametric empirical approaches that are available for estimating the level of energy efficiency the objective of this paper therefore is to sketch out and explain from an economic perspective the theoretical framework as well as the empirical methods for measuring the level of energy efficiency additionally in the second part of the paper some of the empirical studies that have attempted to measure energy efficiency using such an economics approach are summarized and discussed

measuring the contribution of public infrastructure capital in sweden the authors purpose is to examine ways of evaluating and measuring the contribution of public infrastructure capital to private sector output and productivity growth in sweden they do this by specifying and implementing empirically a number of alternative econometric models using annual data for sweden from 1960 to 1988 applying a dual cost function approach they find that increases in public infrastructure capital ceteris paribus reduce private sector costs the authors compute that amount of public infrastructure capital that would rationalize the cost savings incurred by the private business and manufacturing sectors and find that the amount that can be rationalized in this manner is less than what was in fact available in 1988 but that the extent of excess public infrastructure capital has been falling in the 1980s copyright 1992 by the editors of the scandinavian journal of economics

futures markets cognitive ability and mispricing in experimental asset markets we study the effect of a futures market in which contracts maturing in the last period of the life of the asset can be traded our experiment has two treatments one in which a spot market operates on its own and a second treatment in which a spot and a futures market are active simultaneously futures markets lower spot prices but increase price volatility the futures markets themselves exhibit considerable overpricing individuals with higher cognitive reflection test crt scores achieve greater earnings and tend to sell in the overpriced futures market while traders with lower crt scores make purchases in the futures market greater average crt score among a group of traders is associated with better price discovery when no futures market is present but there is no such relationship in the presence of a futures market modified measures of crt which take into account different types of incorrect responses are introduced

a review of bubbles and crashes in experimental asset markets this paper discusses the literature on bubbles and crashes in the most commonly used experimental asset market design introduced by smith et al it documents the main findings based on the results from 41 published papers 3 book chapters and 20 working papers

policy motivation and party differences in a dynamic spatial model of party competition we present a model of party competition that produces more realistic patterns of results than those often emphasized in the literature reversing downs 1957 we assume that parties win elections in order to formulate policies rather than formulate policies in order to win elections voters are modeled first as having perfect information about candidate positions and then under conditions of uncertainty in simulation experiments we show that policy motivation and voter uncertainty can bring about persistent and predictable party differences in sequential majority rule elections as the degree of voter certainty decreases parties diverge towards their optima whereas increases in voter certainty draw parties towards cycles in which party positions vary but predictable issue stances are maintained on the average

a test of the modigliani miller invariance theorem and arbitrage in experimental asset markets modigliani and miller show that the total market value of a firm is unaffected by a repackaging of asset return streams to equity and debt if pricing is arbitrage free we investigate this invariance theorem in experimental asset markets finding value invariance for assets of identical risks when returns are perfectly correlated however exploiting price discrepancies has risk when returns have the same expected value but are uncorrelated in which case the law of one price is violated discrepancies shrink in consecutive markets but persist even with experienced traders in markets where overall trader acuity is high assets trade closer to parity

investment in u s agriculture resource adjustment problems in u s agriculture are motivated against the background of the farm problem the adjustment cost hypothesis is invoked to specify and estimate consistently a system of dynamic investment demand and output supply equations by utilizing recent advances in dynamic duality theory the investment demand equations assume the form of a multivariate flexible accelerator results indicate that labor capital services and land exhibited quasi fixity while intermediate materials were a variable factor this can be construed as a form of asset fixity within aggregate u s agriculture the univariate flexible accelerator hypothesis is rejected
