international diversification works eventually critics of international diversification observe that it does not protect investors against short term market crashes because markets become more correlated during downturns although true this observation misses the big picture over longer horizons underlying economic growth matters more than short lived panics with respect to returns and international diversification does an excellent job of protecting investors

contagion as a wealth effect financial contagion is described as a wealth effect in a continuous time model with two risky assets and three types of traders noise traders trade randomly in one market long term investors provide liquidity using a linear rule based on fundamentals convergence traders with logarithmic utility trade optimally in both markets asset price dynamics are endogenously determined numerically as functions of endogenous wealth and exogenous noise when convergence traders lose money they liquidate positions in both markets this creates contagion in that returns become more volatile and more correlated contagion reduces benefits from portfolio diversification and raises issues for risk management during the f inancial panic associated with the default of the russian government in august 1998 and the subsequent collapse of the hedge fund long term capital management numerous hedge funds banks and securities firms tried simultaneously to reduce exposures to a variety of financial instruments such as russian bonds brazilian stocks u s mortgages spreads between on therun and off the run government securities and spreads between swaps and u s treasuries although the fundamental values of these positions would appear to have little correlation during this financial crisis the asset prices in these markets exhibited the following common empirical pattern 1 financial intermediaries suffered losses as prices moved against their positions 2 market depth and liquidity decreased simultaneously in several markets 3 the volatility of prices increased simultaneously in several markets and

licensing effect in consumer choice abstract most choices in the real world follow other choices or judgments the authors show that a prior choice which activates and boosts a positive self concept subsequently licenses the choice of a more self indulgent option the authors propose that licensing can operate by committing to a virtuous act in a preceding choice which reduces negative self attributions associated with the purchase of relative luxuries five studies demonstrate the proposed licensing effect of a prior commitment to a virtuous act on subsequent choice consistent with the authors theory the preference for an indulgent option diminishes if the licensing task is attributed to an external motivation the authors also report a mediation analysis in support of their theoretical explanation that the licensing effect operates by providing a temporary boost in the relevant self concept

international asset pricing and portfolio diversification with time varying risk we test the conditional capital asset pricing model capm for the world s eight largest equity markets using a parsimonious generalized autoregressive conditional heteroskedasticity garch parameterization our methodology can be applied simultaneously to many assets and at the same time accommodate general dynamics of the conditional moments the evidence supports most of the pricing restrictions of the model but some of the variation in risk adjusted excess returns remains predictable during periods of high interest rates our estimates indicate that although severe market declines are contagious the expected gains from international diversification for a u s investor average 2 11 percent per year and have not significantly declined over the last two decades

evolution of international stock and bond market integration influence of the european monetary union abstract this paper examines the dynamic relationship between daily stock and government bond returns of selected countries over the past decade to infer the state and progress of inter financial market integration we proceed to empirically investigate the influence of the european monetary union emu on time variations in inter stock bond market integration segmentation dynamics using a two step procedure first we document the downward trends in time varying conditional correlations between stock and bond market returns in european countries japan and the us second we investigate the causality and determinants of this interdependent relationship in particular whether the various macroeconomic convergence criteria associated with the emu have played a significant role we find that real economic integration and the reduction in currency risk have generally had the desired effect on financial integration but monetary policy integration may have created uncertain investor sentiments on the economic future of the emu thereby stimulating a flight to quality phenomenon

from inherent value to incentive value when and why pointless effort enhances consumer preference companies typically use clear fonts and bright pictures in their ads web sites and product package designs place their products on easy to reach shelves and emphasize ease of usage to make their products appear desirable to consumers however we suggest that customers focused on incentive value getting the best product may instead see products associated with noninstrumental pointless effort as more desirable we suggest that because effort is usually required to get the best outcomes people looking for the best outcomes also mistakenly presume effort must imply the best possible outcome across five studies we show that highlighting incentive value for instance by message framing or by measuring chronic focus or by manipulating situational focus on incentive value enhances preference toward outcomes associated with noninstrumental effort we discuss the importance of our findings for understanding everyday consumption decisions and argue for a widespread tendency among individuals wanting the best to infer value from noninstrumental effort

market overreaction and investment strategies we investigated the overreaction of the korean market in response to shocks in the us stock market and analysed the dynamic relationship between these two markets since 1996 we found that the kospi 200 index futures overreacted to the s p 500 index returns during the period from 2000 to 2009 when the korean market was in its growth stage as the korean market matured and the kospi 200 overnight futures were introduced in 2009 the overreaction disappeared when investors employed the kelly model or value at risk to exploit the overreaction their trading strategies produced significant profits during the growth stage even after considering transaction costs and risk but the profits attenuated once the overnight futures market was launched in 2009

consumer preference for a no choice option the traditional focus in the decision making literature has been on understanding how consumers choose among a given set of alternatives the notion that preference uncertainty may lead to choice deferral when no single alternative has a decisive advantage is tested in seven studies building on recent research the article shows that the decision to defer choice is influenced by the absolute difference in attractiveness among the alternatives provided and is not consistent with trade off difficulty or the theory of search these findings are then extended to show that choice deferral can also be modified for the same alternatives by manipulations that make them appear more similar in attractiveness or that decrease the need to differentiate among them the results are consistent with the notion that preference uncertainty results in a hesitation to commit to any single action since small differences in attractiveness among the alternatives are potentially reversible consistent with this premise the effect of attractiveness difference on choice deferral decreased significantly when subjects were first allowed to practice making monetary trade offs among the available alternatives

concordance in global office market cycles stevenson s akimov a hutson e and krystalogianni a concordance in global office market cycles regional studies a large proportion of international real estate investment is concentrated in the office markets of the world s largest cities however many of these global cities are also key financial services centres highlighting the possibility of reduced economic diversification from an investor s perspective this paper assesses the degree of synchronization in cycles across twenty of the world s largest office markets finding evidence of significant concordance across a large number of markets the results highlight the problems associated with commonalities in the underlying economic bases of the markets the concentration of investment also raises the possibility of common flow of funds effects that may further reduce diversification opportunities

are some groups more vulnerable to macroeconomic shocks than others hypothesis tests based on panel data from peru abstract which socio economic groups are most vulnerable to welfare declines during a macroeconomic shock after clarifying the difference between poverty and vulnerability this paper presents an analytical framework and applies it to panel data from peru major findings are 1 households with better educated heads are less vulnerable 2 female headed households are no more vulnerable than male headed households 3 households with more children are more vulnerable 4 transfer networks that assist the poor in relatively stable periods do not protect them during a major shock unless they originate from outside peru and 5 peru s social security program is targeted neither to vulnerable nor to poor households but other transfer programs are better targeted

state credit programs and the peasantry under populist regimes lessons from the apra experience in the peruvian amazon abstract a study near iquitos peru finds that a national agricultural program implemented in the late 1980s which provided peasants with access to credit secure land tenure and grassroots organization promised to reduce rather than improve the welfare of intended beneficiaries new economic conditions and strategic behaviors engendered by the program threatened to combine through a process of community enclosure and competitive exclusion to undermine the subsistence viability of peasant communities general lessons are drawn for more effective rural development programs ones that pay particular attention to direct and indirect feedback effects of macroeconomic policy the factors that limit peasant economic competitiveness and to the fundamental spatiality of development processes

when more is less and less is more the role of ideal point availability and assortment in consumer choice contrary to the common wisdom that more choice is always better selections made from large assortments can lead to weaker preferences building on the extant literature this research identifies ideal point availability as a key factor moderating the impact of assortment on choice it is proposed that in the case of large assortments ideal point availability can simplify choice leading to a stronger preference for the selected alternative in contrast for choices made from smaller assortments ideal point availability is proposed to have the opposite effect leading to weaker preferences data obtained from four experiments lend support for the theory and the empirical predictions advanced in this article

technology diffusion and public policy a useful typology of technological change is provided by the schumpeterian trilogy invention the generation of new ideas innovation the development of those ideas through to the first marketing or use of a technology and diffusion the spread of new technology across its potential market until recently policy schemes in most oecd countries have tended to focus predominantly on the invention and innovation or science and r d end of this technology spectrum see e g limpens et al i 992 although it is generally realised that it is the process of diffusion or use of technology that creates productive potential and competitiveness policy initiatives have largely bypassed opportunities to improve the diffusion process if this may seem misplaced emphasis it does in fact reflect the state of the academic literature which is wide ranging and extensive as it relates to policies on r d but small and fragmented as regards policies on diffusion currently a gradual reorientation of policy direction toward diffusion seems to be taking place the us and uk governments for example have recently proposed major technology policy initiatives that despite differences in emphasis both stress the importance of creating an infrastructure conducive to a rapid spread of awareness and knowledge of innovations we argue that although sensible in themselves such policies may be too limited in scope and that a broader policy stance may be needed this paper has two main objectives the first is to provide an overview of why policy intervention in the diffusion process may be desirable and what form it might take this discussion is rather long since to the best of our knowledge there is no published systematic synthesis of the diffusion policy literature though see stoneman i987 for an earlier attempt the second aim is to look at actual diffusion policies and their impacts to make the task manageable we are restricting this paper to a discussion of the diffusion of new process technologies although similar issues apply to new consumer technologies these are not explicitly addressed we also consider diffusion policy only within the context of a given institutional and macroeconomic environment although it may well be that the supply of skilled manpower the nature of the capital market animal spirits and entrepreneurship fiscal and monetary policies will all impact upon the diffusion path improvements in these areas will also impact upon a whole host of other aspects of the economy s performance to use a plea for diffusion policy as a rationale for changes in such areas would be equivalent to the tail wagging the dog and thus they fall outside the remit of this paper

bank integration and co movements across housing markets this paper investigates whether bank integration measured by cross border bank flows can capture the co movements across housing markets in developed countries by using a spatial dynamic panel model the transmission can occur through a global banking channel in which global banks intermediate wholesale funding to local banks changes in financial conditions are passed across borders through the banks balance sheet exposure to credit currency maturity and funding risks resulting in house price spillovers while controlling for country level and global factors we find significant co movement across housing markets of countries with proportionally high bank integration bank integration can better capture house price co movements than other measures of economic integration once we account for bank exposure other spatial linkages traditionally used to account for return co movements across region such as trade foreign direct investment portfolio investment geographic proximity etc become insignificant moreover we find that the co movement across housing markets decreases for countries with less developed mortgage markets characterized by fixed mortgage rate contracts low limits of loan to value ratios and no mortgage equity withdrawal

information trading volume and international stock return comovements evidence from cross listed stocks we investigate the joint dynamics of returns and trading volume of 556 foreign stocks cross listed on u s markets heterogeneous agent trading models rationalize how trading volume reflects the quality of traders information signals and how it helps to disentangle whether returns are associated with portfolio rebalancing trades or information motivated trades based on these models we hypothesize that returns in the home u s market on high volume days are more likely to continue to spill over into the u s home market for those cross listed stocks subject to the risk of greater informed trading our empirical evidence provides support for these predictions which confirms the link between information trading volume and international stock return comovements that has eluded previous empirical investigations

correlations in price changes and volatility across international stock markets the short run interdependence of prices and price volatility across three major international stock markets is studied daily opening and closing prices of major stock indexes for the tokyo london and new york stock markets are examined the analysis utilizes the autoregressive conditionally heteroskedastic arch family of statistical models to explore these pricing relationships evidence of price volatility spillovers from new york to tokyo london to tokyo and new york to london is observed but no price volatility spillover effects in other directions are found for the pre october 1987 period article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

infrastructure investment a review essay economists try not to be faddists but they often cannot help themselves while work on a topic should mirror the prospective importance of the topic that situation seems to occur with disappointing frequency instead the usual pattern is that some reasonably important topic will be totally ignored for the longest time then recognized and then the subject of a flurry of work all out of proportion to its likely long run importance nowhere has this speculative bubble of economic research been more clearly illustrated than with infrastructure investment macroeconomists havelong felt that the stock of public capital is an important factor input in the production of total output macroeconomists have known that u s productivity growth slowed dramatically in about 1973 and macroeconomists should have known that united states investment in public capital has been down since the late 1960s yet analysis of the u s productivity slowdown completely ignored infrastructure investment for the first fifteen years of this slowdown concentrating instead on energy prices social regulation the composition of the work force research and development different rates of obsolescence of the private capital stock and any number of other matters the public capital stock was hardly ever even mentioned as a potential factor in the productivity slowdown aschauer changed all that he wrote a series of papers 1989a 1989b 1989c that put these two movements together econometrically infrastructure investment turned down and aggregate productivity turned down slightly later both in the united states and in some other developed countries his work hit the magic button those who had worried about the productivity puzzle for fifteen years welcomed a new suspect those who were worried about low rates of u s national saving welcomed a new way to make their argument even more forcefully than with official figures on saving and investment which do not count infrastructure investment as investment political liberals and liberal politicians saw a way to rescue government spending and projects from the assaults of reaganism and even a way to avoid oth

ownership occupation and risk a view of the city of london office market office returns in the city of london are more volatile than in other uk markets this volatility may reflect fluctuations in capital flows associated with changing patterns of ownership and the growing linkage between real estate and financial markets in the city using current and historical data patterns of ownership in the city are investigated they reveal that overseas ownership has grown markedly since 1985 that owners are predominantly fire sector firms and that there are strong links between ownership and occupation this raises concerns about future volatility and systemic risk in a market strongly influenced by the cyclical behaviour and shocks of the international financial system

the cross over effect of irrational sentiments in housing commercial property and stock markets abstract this paper examines the dependence in irrational sentiments across housing commercial property and stock markets our empirical results document an important and lasting impact that commercial real estate sentiment and returns have on broader financial markets we also show that the cross over effects of market sentiments are not consistent with cross over effects in market returns sentiments and returns in housing and stock markets exhibit strong dependence on other markets whereas they evolve independently in commercial real estate while housing and stock market returns respond to irrational sentiment in commercial real estate markets the opposite is not true

does industrial structure explain the benefits of international diversification abstract we examine the influence of industrial structure on the cross sectional volatility and correlation structure of country index returns for 12 european countries between 1978 and 1992 we find that industrial structure explains very little of the cross sectional difference in country return volatility and that the low correlation between country indices is almost completely due to country specific sources of return variation diversification across countries within an industry is a much more effective tool for risk reduction than industry diversification within a country

dynamic hedging and extreme asset co movements the paper investigates the portfolio allocation effects of increased asset co movements during market downturns we develop a model for the stock price process that allows for increased and asymmetric dependence between extreme return realizations we isolate the portfolio hedging demands that arise due to extreme co movements and find a substantial shift of the portfolio holdings toward the risk free asset we demonstrate that accounting for dependence between extreme events in portfolio decisions leads to significant economic gains that stem primarily from intertemporal hedging motives these findings are robust along alternative modeling assumptions of extreme co movements and conditional correlation

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

detrending stylized facts and the business cycle the stylized facts of macroeconomic time series can be presented by fitting structural time series models within this framework we analyse the consequences of the widely used detrending technique popularised by hodrick and prescott 1980 it is shown that mechanical detrending based on the hodrick prescott filter can lead investigators to report spurious cyclical behaviour and this point is illustrated with empirical examples structural time series models also allow investigators to deal explicitly with seasonal and irregular movements that may distort estimated cyclical components finally the structural framework provides a basis for exposing the limitations of arima methodology and models based on a deterministic trend with a single break

international office investment in global cities the production of financial space and systemic risk lizieri c and pain k international office investment in global cities the production of financial space and systemic risk regional studies the paper explores the relationships between uk commercial real estate and regional economic development as a foundation for the analysis of the role of real estate investment in local economic development linkages between economic growth development real estate performance and investment allocations are documented long run regional property performance is not the product of long run economic growth and weakly related to indicators of long run supply and demand changes in regional portfolio weights seem driven by neither market performance nor underlying fundamentals in the short run regional investment shifts show no clear leads or lags with market performance

infant health during the 1980s peruvian crisis and long term economic outcomes summary in 1988 peru entered a severe economic crisis as a corollary of unfavorable external economic conditions high levels of debt and heterodox policies the so called debt crisis of 1980s this paper investigates the short term health shock experienced by infants during the crisis and its long term impact on human capital accumulation because no longitudinal data are available the estimation of causal effects is performed using multiple cross section surveys that are representative of the same population over time the short term and the long term effects are estimated exploiting the heterogeneous impact of the crisis across and within birth cohorts results indicate that the peruvian crisis significantly affected the health of infants particularly that of children born to low educated mothers from 1988 to 1990 vaccination declined 12 percentage points and infant mortality increased 2 3 percentage points among children born to low educated mothers in the long run the children who suffered the most severe health shocks during the economic downturn of the 1980s performed worse in school they had 0 12 fewer years of formal education and their probability of completing primary education by age 15 was three percentage points lower in relation to similar children born after the crisis the results have strong policy implications children in developing countries should be safeguarded against health shocks during economic crises to avoid a decline in the accumulation of human capital in the long run

do food and oil prices co move abstract this paper studies co movements between world oil prices and global prices for corn soybean and wheat using copulas several copula models with different conditional dependence structures and time varying dependence parameters were considered empirical results for weekly data from january 1998 to april 2011 showed weak oil food dependence and no extreme market dependence between oil and food prices these results support the neutrality of agricultural commodity markets to the effects of changes in oil prices and non contagion between the crude oil and agricultural markets however dependence increased significantly in the last three years of the sampling period even though upper tail dependence remained insignificant indicating that food price spikes are not caused by positive extreme oil price changes these results have implications for policy design risk management and hedging strategies

international transmission mechanisms and contagion in housing markets this paper explores international transmission mechanism and its role in contagion effect in the housing markets across six major asian cities the analysis is based on the identification of house price diffusion effects through a global vector autoregressive gvar model estimated using quarterly data for six major asian cities hong kong tokyo seoul singapore taipei and bangkok from 1991q1 to 2011q2 the empirical results indicate that the open economies heavily relying on international trade such as singapore japan tokyo taiwan taipei and thailand bangkok show positive correlations between the economy s openness and house prices which is consistent with the balassa samuelson hypothesis interestingly some region specific conditions also appear to play important roles as determinants of house price movements which may be driven by restrictive housing policies and demand supply imbalances such as singapore and bangkok these results are reasonably robust across several model specifications the findings bear significant implications for formulation of investment strategy and public policies

the role of explanations and need for uniqueness in consumer decision making unconventional choices based on reasons this research investigates the interaction between a very common task explaining decisions and an individual difference need for uniqueness nfu on buyer decision making we propose that explaining or providing reasons for decisions shifts the focus from the choice of options to the choice of reasons furthermore buyers who explain their decisions and have high nfu tend to select unconventional reasons and are consequently more likely to make unconventional choices these predictions were supported in a series of studies involving choices between conventional and less conventional options such as whether to switch to a brand on sale whether to select a compromise option and whether to accept a gamble with a possible loss the findings also indicate that the effects of providing reasons are not due to attempts to act rationally or to concerns about being evaluated three boundary conditions on the generalization that high nfu consumers who provide reasons tend to make unconventional choices we

are results from non hypothetical choice based conjoint analyses and non hypothetical recoded ranking conjoint analyses similar conflicting findings have been found in previous research that compared choice based conjoint analysis and ranking conjoint analysis in a public good setting the present paper revisits this issue for a private good in a non hypothetical context using small and large choice sets our results suggest that in a small choice set setting participants preferences and willingness to pay are similar across the two conjoint analysis formats however in large choice sets a divergence between the two conjoint analysis formats emerges hence the two conjoint analysis formats can only be used interchangeably in small choice sets not in large choice sets

international transmission of u s monetary policy shocks evidence from stock prices this paper analyzes intraday changes in firm level equity prices around interest rate announcements to assess the transmission of u s monetary policy to the global economy we document that foreign firms on average are roughly as sensitive to u s monetary policy as u s firms although we also find considerable cross sectional variation across firms in particular foreign stocks in cyclically sensitive industries show stronger responses to interest rate surprises consistent with a demand channel of policy transmission in addition transmission of u s policy appears to be stronger to economies with fixed exchange rates evidence for a credit channel is weaker

the effect of forced choice on choice abstract whereas most academic and industry studies of consumer preferences and decision making involve forced choice i e participants are told to choose one of the presented product or service alternatives buyers usually also have the option not to select any alternative an implicit assumption in the experimental practice of forcing choice is that the no choice option draws proportionately from the various available alternatives such that the qualitative conclusions are unaffected however the authors propose that the no choice option competes most directly with alternatives that buyers tend to select when they are uncertain about their preferences building on this general proposition the authors show that the introduction of the no choice option strengthens the attraction effect weakens the compromise effect and decreases the relative share of an option that is average on all dimensions they also examine the mechanisms underlying the impact of having the option not to choose and the condi

technical change and the urban development cycle the paper describes the pronounced long swings or urban development cycles of 20 30 years duration which have created successive waves of urbanisation in the british economy since the industrial revolution and which can be related to successive long waves of technological development within the economy as a whole a more detailed examination of the post war period shows that in each sector of building two types of shorter cycles causing pronounced building booms and slumps are superimposed on the dominant long swing of post war urban development the discussion concludes by examining the prospects for the next urban development cycle in britain related to the new wave of micro electronic and information technologies and then draws out the main policy implications of the analysis

shifts in volatility driven by large stock market shocks abstract this paper presents an extension of the stochastic volatility model which allows for level shifts in volatility of stock market returns known as structural breaks these shifts are endogenously driven by large return shocks innovations reflecting large pieces of market news these shocks are identified from the data as being bigger in absolute terms than the values of two threshold parameters of the model one for the negative shocks and one for the positive shocks the model can be employed to investigate different sources of stock market volatility shifts driven by market news without relying on exogenous information in addition to this it has a number of interesting features which enable us to study the effects of large return shocks on future levels of market volatility the above properties of the model are shown based on a study for the us stock market volatility

are correlations of stock returns justified by subsequent changes in national outputs abstract in an integrated world capital market the same pricing kernel is applicable to all securities we apply this idea to the stock returns of different countries we investigate the underlying determinants of cross country stock return correlations first we determine for a given measured degree of commonality of country outputs what should be the degree of correlation of national stock returns we propose a framework that contains a statistical model for output and an intertemporal financial market model for stock returns we then attempt to match the correlations generated by the model with measured correlations our results show that under the hypothesis of market segmentation the model correlations are much smaller than observed correlations however assuming world markets are integrated our model correlations can be matched with observed correlations

self control for the righteous toward a theory of precommitment to indulgence prior research has examined consumers use of self control to avoid hedonic myopic temptations such as overspending and smoking in this research we investigate the opposite form of self control whereby consumers force themselves to indulge and avoid default forms of spending on utilitarian necessities and or savings in particular consumers who have difficulty choosing items that are perceived as indulgences or luxuries e g a cruise over necessities e g saving for college education and cash in everyday decisions may use precommitments to indulgence especially when the psychological cost of such commitments is less concrete these propositions were tested in a series of studies involving real and hypothetical choices as well as process measures the results indicate that a substantial segment of consumers choose hedonic luxury rewards over cash of equal or greater value consumers typically explain such choices based on the need to precommit to indulgence to make sure that the award does no

stock market cycles financial liberalization and volatility in this paper we analyze the cycles of the stock markets in four latin american and two asian countries and we compare their characteristics we divide our sample in two subperiods in order to account for differences induced by the financial liberalization processes of the early 1990s we find that cycles in emerging countries tend to have shorter duration and larger amplitude and volatility than in developed countries however after financial liberalization latin american stock markets have behaved more similarly to stock markets in developed countries whereas asian countries have become more dissimilar concordance of cycles across markets has increased significantly over time especially for latin american countries after liberalization

dynamic equilibrium with two stocks heterogeneous investors and portfolio constraints we study dynamic equilibrium in a lucas economy with two stocks two heterogeneous constant relative risk aversion investors and portfolio constraints we focus on margin and leverage constraints which restrict access to credit we find a positive relationship between the amount of leverage in the economy and magnitudes of stock return correlations and volatilities tighter constraints generate rich patterns in correlations and volatilities make them less countercyclical increase risk premia proportionally to assets margins and increase prices of low margin assets more than prices of high margin assets we derive closed form solutions for the unconstrained case and the case of leverage constraints

the economics of product variety a survey demand for variety may arise from a taste for diversity in individual consumption and or from diversity in tastes even when each consumer chooses a single variant the full degree of variety potentially demanded will not in general be supplied because scale economies even to a small degree mean that the potential welfare or revenue gain from greater variety must be balanced against the lower unit production costs with fewer variants the economics of product variety consists essentially in analysing the effect of this balance in different situations and comparing the degree of product variety for different market structures with each other and with the optimum the survey commences with the work on market structures with single product firms generalized monopolistic competition tracing modern developments in both the chamberlinian and hotelling traditions the latter has been particularly fruitful due to the expansion of the original locational ideas into virtual spaces in product characteristics the emphasis in recent work on product variety has been on multiproduct firms in both monopolistic and oligopolistic structures including strategic market preemption although most work has been in a full information context there have been advances in product variety under imperfect information either by consumers to properties of the firms products or firms as to consumers demands

common volatility in international equity markets in this article we take advantage of the time varying structure of stock returns variances to investigate whether two international stock markets share the same volatility process we use a test recently developed by engle and kozicki this test is also used to assess the validity of a one factor autoregressive conditional heteroscedasticity model we find that some international stock markets have the same time varying volatility

speculative behavior and the dynamics of interacting stock markets abstract we develop a simple agent based financial market model in which heterogeneous speculators apply technical and fundamental analysis to trade in two different stock markets speculators strategy market selections are repeated at each time step and depend on predisposition effects herding behavior and market circumstances simulations reveal that our model is able to explain a number of nontrivial statistical properties of and between international stock markets including bubbles and crashes fat tailed return distributions volatility clustering persistent trading volume coevolving stock prices and cross correlated volatilities against this background our model may be deemed to have been validated

market efficiency around the clock some supporting evidence using foreign based derivatives abstract this paper examines whether information across international markets is rationally incorporated into stock prices we find that japanese nikkei index based futures traded in the u s provide complete information about contemporaneous overnight japanese returns moreover existing cross dependence between the u s and japanese stock index returns is subsumed by the information content of the derivative securities our findings cast doubt on trading models based on irrational traders who either overreact or only partially adjust to movements in foreign stock markets

on the volatility and comovement of u s financial markets around macroeconomic news announcements the objective of this paper is to provide a deeper insight into the links between financial markets and the real economy to that end we study the short term anticipation and response of u s stock treasury and corporate bond markets to the first release of surprise u s macroeconomic information specifically we focus on the impact of these announcements not only on the level but also on the volatility and comovement of those assets returns we do so by estimating several extensions of the parsimonious multivariate garch dcc model of engle 2002 for the excess holding period returns on seven portfolios of these asset classes we find that both the process of price formation in each of those financial markets and their interaction appear to be driven by fundamentals yet our analysis reveals a statistically and economically significant dichotomy between the reaction of the stock and bond markets to the arrival of unexpected fundamental information we also show that the conditional mean volatility and comovement among stock treasury and corporate bond returns react asymmetrically to the information content of these surprise announcements overall the above results shed new light on the mechanismsbywhichnewinformationisincorporatedintopriceswithinandacrossu s financial markets

further evidence on international islamic and conventional portfolios diversification under regime switching abstractthis article investigates the comparative performance of international islamic and conventional portfolio diversification across different financial market regimes and provides an optimal choice from an american investor s viewpoint during the period 2002 2014 using a bootstrap based stochastic dominance sd test and monthly msci prices of islamic stock market indices and their conventional counterparts in 38 countries from north and latin america europe and asia pacific regions we find that sd relationships between islamic and conventional optimal diversified portfolios change systematically according to investment region and market regime essentially for all regimes us investors are indifferent between islamic diversification and its conventional counterpart which implies that arbitrage diversification opportunities are rare and short lived in all regions however across all regions especially in a crisis regime islamic portfolio diversification can be a good substitute for convention

information trading and stock returns lessons from dually listed securities this paper compares the intra day patterns on the nyse and amex of volatility trading volume and bid ask spreads for european and japanese dually listed stocks with american stocks of comparable average trading volume and volatility it is shown that the intra day patterns for these stocks are remarkably similar even though public information flows differ markedly across these stocks during the trading day in the early morning all stocks have higher volatility than later in the day but this phenomenon is most pronounced for japanese stocks and affects american stocks the least we argue that these patterns are consistent with markets reacting to the overnight accumulation of public information but are inconsistent with the view that early morning volatility can be attributed to monopolistic specialist behavior

risk sharing and counter cyclical variation in market correlations abstract i present a consumption based dynamic asset pricing model in which international market correlations vary counter cyclically over time the driving force in the model is the time varying effective risk aversion induced by external habit formation market returns are driven by fundamental outputs and discount rates when risk aversion is high the effect of discount rates on market returns rises with the market price of risk to the extent that countries share risk the cross country correlation of discount rates exceeds the cross country correlation of fundamental outputs in bad times market correlations rise as returns are mostly driven by discount rates thus consistent with the empirical evidence periods of high risk aversion are associated with high market correlations and high market volatility after calibration my model is consistent with the observed variation in market correlations as well as other features of asset prices including the equity premium and market volatility

index futures arbitrage and the behavior of stock index futures prices this article examines intraday transaction datafor s p 500 stock indexfutures prices and the intraday quotes for the underlying index the data indicate that thefutures price changes are uncorrelated and that the variability of these price changes exceeds the variability ofprice changes in the s p 500 index this excess variability of the futures over the index remains even after controlling for the nonsynchronous prices in the index quotes which induces autocorrelation in the index changes we advance and examine empirically two hypotheses regarding the difference between the futures price and its theoretical value that this mispricing increases on average with maturity and that it is path dependent evidence supporting these hypotheses is presented

is public expenditure productive abstract this paper considers the relationship between aggregate productivity and stock and flow government spending variables the empirical results indicate that i the nonmilitary public capital stock is dramatically more important in determining productivity than is either the flow of nonmilitary or military spending ii military capital bears little relation to productivity and iii a core infrastructure of streets highways airports mass transit sewers water systems etc has most explanatory power for productivity the paper also suggests an important role for the net public capital stock in the productivity slowdown of the last fifteen years

the red and the black mental accounting of savings and debt in the standard economic account of consumer behavior the cost of a purchase takes the form of a reduction in future utility when expenditures that otherwise could have been made are forgone the reality of consumer hedonics is different when people make purchases they often experience an immediate pain of paying which can undermine the pleasure derived from consumption the ticking of the taxi meter for example reduces one s pleasure from the ride we propose a double entry mental accounting theory that describes the nature of these reciprocal interactions between the pleasure of consumption and the pain of paying and draws out their implications for consumer behavior and hedonics a central assumption of the model which we call prospective accounting is that consumption that has already been paid for can be enjoyed as if it were free and that the pain associated with payments made prior to consumption but not after is buffered by thoughts of the benefits that the payments will finance another important concept is coupling which refers to the degree to which consumption calls to mind thoughts of payment and vice versa some financing methods such as credit cards tend to weaken coupling whereas others such as cash payment produce tight coupling our model makes a variety of predictions that are at variance with economic formulations contrary to the standard prediction that people will finance purchases to minimize the present value of payments our model predicts strong debt aversion that they should prefer to prepay for consumption or to get paid for work after it is performed such pay before sequences confer hedonic benefits because consumption can be enjoyed without thinking about the need to pay for it in the future likewise when paying beforehand the pain of paying is mitigated by thoughts of future consumption benefits contrary to the economic prediction that consumers should prefer to pay at the margin for what they consume our model predicts that consumers will find it less painful to pay for and hence will prefer flat rate pricing schemes such as unlimited internet access at a fixed monthly price even if it involves paying more for the same usage other predictions concern spending patterns with cash charge or credit cards and preferences for the earmarking of purchases we test these predictions in a series of surveys and in a conjoint like analysis that pitted our double entry mental accounting model against a standard discounting formulation and another benchmark that did not incorporate hedonic interactions between consumption and payments our model provides a better fit of the data for 60 of the subjects the discounting formulation provides a better fit for only 29 of the subjects even when allowing for positive and negative discount rates the pain of paying we argue plays an important role in consumer self regulation but is hedonically costly from a hedonic perspective the ideal situation is one in which payments are tightly coupled to consumption so that paying evokes thoughts about the benefits being financed but consumption is decoupled from payments so that consumption does not evoke thoughts about payment from an efficiency perspective however it is important for consumers to be aware of what they are paying for consumption this creates a tension between hedonic efficiency and what we call decision efficiency various institutional arrangements such as financing of public parks through taxes or usage fees play into this tradeoff a producer developing a pricing structure for their product or service should be aware of these two conflicting objectives and should try to devise a structure that reconciles them

choice based on reasons the case of attraction and compromise effects building on previous research this article proposes that choice behavior under preference uncertainty may be easier to explain by assuming that consumers select the alternative supported by the best reasons this approach provides an explanation for the so called attraction effect and leads to the prediction of a compromise effect consistent with the hypotheses the results indicate that 1 brands tend to gain share when they become compromise alternatives in a choice set 2 attraction and compromise effects tend to be stronger among subjects who expect to justify their decisions to others and 3 selections of dominating and compromise brands are associated with more elaborate and difficult decisions

linkages in international stock markets evidence from a classification procedure in this article we propose a new approach to evaluate the predictable components in stock indices using a boosting based classification technique and we use this method to examine causality among the three main stock market indices in the world during periods of large positive and negative price changes the empirical evidence seems to indicate that the standard poors 500 index contains incremental information that is not present in either the ftse 100 index financial times stock exchange index or the nikkei 225 index and that could be used to enhance the predictability of the large positive and negative returns in the three main stock market indices in the world this in turn would suggest a causality relationship running from the standard poors 500 index to both the ftse 100 and the nikkei 225 indices

contagion in latin america definitions measurement and policy implications this paper analyzes bond and stock markets in latin america and uses these patterns to investigate whether contagion occurred in the 1990 s it defines shift contagion as a significant increase in cross market linkages after a shock to one country or region several coin toss examples and a simple model show that the standard tests for contagion are biased due to the presence of heteroscedasticity endogeneity and omitted variable bias recent empirical work which addresses these problems finds little evidence of shift contagion during a range of crisis periods instead this work argues that many countries are highly interdependent in all states of the world and the strong cross country linkages which exist after a crisis are not significantly different than those during more stable periods these findings have a number of implications for latin america

yes but this other one looks better works better how do consumers respond to trade offs between sustainability and other valued attributes consumers are increasingly facing product evaluation and choice situations that include information about product sustainability i e information about a product s relative environmental and social impact in many cases consumers have to make decisions that involve a trade off between product sustainability and other valued product attributes similarly product and marketing managers need to make decisions that reflect how consumers will respond to different trade off scenarios in the current research we study consumer responses across two different possible trade off scenarios one in which consumers face a trade off between product sustainability and hedonic value and another in which they must trade off between product sustainability and utilitarian value our results suggest that overall consumers are more likely to trade off hedonic value e g esthetics for sustainability than to trade off utilitarian value e g functional performance for sustainability in studies 1a and 1b we presented participants with a product choice task and also measured their anticipatory emotions as they contemplated their options the results suggest that given a trade off consumers are more likely to choose a sustainable product when they have to trade off hedonic value than when they have to trade off utilitarian value further these studies provide some insight into the emotions underlying this effect in study 2 we use a different consumer response measure relative purchase likelihood and investigate the effect of trade off type across categories that vary in the degree to which hedonic and utilitarian attributes are perceived to be important referred to as product type our results suggest that the effect of trade off type still holds yet is moderated by product type such that consumers greater willingness to trade off hedonic value vs utilitarian value for sustainability is attenuated as the relative importance of hedonic vs utilitarian attributes increases in addition to building on our theoretical understanding of decision making given trade offs with moral attributes this research is also intended to support managers as they define and choose among various strategic product development and marketing promotion options

the effects of market segmentation and investor recognition on asset prices evidence from foreign stocks listing in the united states non u s firms cross listing shares on u s exchanges as american depositary receipts earn cumulative abnormal returns of 19 percent during the year before listing and an additional 1 20 percent during the listing week but incur a loss of 14 percent during the year following listing we show how these unusual share price changes are robust to changing market risk exposures and are related to an expansion of the shareholder base and to the amount of capital raised at the time of listing our tests provide support for the market segmentation hypothesis and merton s 1987 investor recognition hypothesis the globalization of u s capital markets has accelerated dramatically in the past decade increasing numbers of companies from overseas have chosen to either raise capital through global equity issues or prepare for future capital raising by way of cross listings on u s exchanges as of 1997 about 1 300 non u s companies have listed their shares for trading on the new york stock exchange nyse the american exchange amex the national association of securities dealers automation quotation nasdaq system or

the world price of jump and volatility risk abstract we study international integration of markets for jump and volatility risk using index option data for the main global markets to explain the cross section of expected option returns we focus on return based multi factor models for each market separately we provide evidence that volatility and jump risk are priced risk factors there is little evidence however of global unconditional pricing of these risks we show that uk and us option markets have become increasingly interrelated and using conditional pricing models generates some evidence of international pricing finally the benefits of diversifying jump and volatility risk internationally are substantial but declining

variety vice and virtue how assortment size influences option choice assortment size has been shown to influence whether consumers make a choice but could it also influence what they choose five studies demonstrate that because choosing from larger assortments is often more difficult it leads people to select options that are easier to justify virtues and utilitarian necessities are generally easier to justify than indulgences consequently choosing from larger assortments often shifts choice from vices to virtues and from hedonic to utilitarian options these effects reverse however when situational factors provide accessible reasons to indulge underscoring the role of justification implications for choice difficulty and justification processes are discussed

structural adjustment policies income distribution and poverty a review of the jamaican experience abstract although jamaica has had structural adjustment and standby loans from the world bank and the international monetary fund imf since 1977 the implementation of typical structural adjustment policies such as trade and financial liberalization privatization and labor market reform has for the most part occurred only since 1989 during 1989 1993 when the jamaican economy underwent the most drastic liberalization policies inequality and poverty declined although there were sharp jumps in both inequality and poverty in 1991 when financial liberalization occurred the overall decline in poverty is attributed to the strong performance of domestic agriculture and the increased inflow of remittances and seems unlikely to be sustained

how do crude oil prices co move a copula approach abstract this paper examines the dependence structure between crude oil benchmark prices using copulas by considering several copula models with different conditional dependence structures and time varying dependence parameters we find evidence of significant symmetric upper and lower tail dependence between crude oil prices these findings suggest that crude oil prices are linked with the same intensity during bull and bear markets thus supporting the hypothesis that the oil market is one great pool in contrast with the hypothesis that states that the oil market is regionalized our findings on crude oil price co movements also have implications for risk management hedging strategies and asset pricing

the discriminating consumer product proliferation and willingness to pay for quality abstract the authors propose that a crowded product space motivates consumers to better discriminate between options of different quality specifically this article reports evidence from three controlled experiments and one natural experiment that people are prepared to pay more for high quality products and less for low quality products when they are considered in the context of a dense as opposed to a sparse set of alternatives to explain this effect the authors argue that consumers uncertain about the importance of quality learn from observing market outcomes product proliferation reveals that other consumers care to discriminate among similar alternatives and in turn this inference raises the importance of quality in decision making

why do markets move together an investigation of u s japan stock return comovements this article explores the fundamental factors that affect cross country stock return correlations using transactions data from 1988 to 1992 we construct overnight and intraday returns for a portfolio of japanese stocks using their nyse traded american depository receipts adrs and a matched sample portfolio of u s stocks we find that u s macroeconomic announcements shocks to the yen dollar foreign exchange rate and treasury bill returns and industry effects have no measurable influence on u s and japanese return correlations however large shocks to broadbased market indices nikkei stock average and standard and poor s 500 stock index positively impact both the magnitude and persistence of the return correlations stock return cross country covariances play a key role in international finance changes in these covariances affect the volatility of portfolios and asset prices as these covariances increase one expects that a fewer domestic risks are internationally diversifiable so portfolio volatility increases b the risk premium on the world market portfolio increases 1 c the cost of capital increases for individual firms and d the domestic version of the capm becomes increasingly inadequate 2 despite the important economic consequences of changes in cross country covariances the determinants of the levels and dynamics of these covariances have been little studied from an academic

structures investment and economic growth a long term international comparison interest has grown again in recent years about the long term and cyclical nature of building investment and its effect on the macroeconomy this paper investigates the nature of building trends and cycles from the 19th century to the present day for eight major oecd economies focusing predominantly on non housing structures the kalman filter is used to decompose the series into trends and cycles it was found that building cycles exist in all countries though with considerable variation comparisons of volatility between countries and between the different types of fixed investment are made the long run share of fixed investment in structures as a proportion of national income is investigated consideration is given to whether international building investment trends are coincident and an analysis made of the long term correlation between structures investment cycles

markets and the structure of the housebuilding industry an international perspective this paper sets out to examine why the modern housebuilding industry is organised in the ways it is and to identify some implications for the wider operation of housing markets it concentrates on advanced economies and the impacts of market conditions regulatory constraints production characteristics institutional structures and land supply widespread differences occur across countries in the ways in which housebuilding is institutionally structured it is argued that these differences are generally explicable in economic terms and that regulatory practices determine much of the variation

trading volume and serial correlation in stock returns this paper investigates the relationship between aggregate stock market trading volume and the serial correlation of daily stock returns for both stock indexes and individual large stocks the first order daily return autocorrelation tends to decline with volume the paper explains this phenomenon using a model in which risk averse market makers accommodate buying or selling pressure from liquidity or noninformational traders changing expected stock returns reward market makers for playing this role the model implies that a stock price decline on a high volume day is more likely than a stock price decline on a low volume day to be associated with an increase in the expected stock return
