trying to explain home bias in equities and consumption investors hold a substantially larger proportion of their wealth portfolios in domestic assets than standard portfolio theory would suggest a phenomenon called equity home bias in the absence of this bias investors would optimally diversify domestic output risk using foreign equities therefore consumption growth rates would tend to co move across countries even when output growth rates do not empirically however consumption growth rates tend to have a lower correlation across countries than do output growth rates a phenomenon i call consumption home bias in this paper i discuss these two biases and their potential relationship as suggested by the literature

trading halts and market activity an analysis of volume at the open and the close this paper analyzes how the daily opening and closing of financial markets affect trading volume we model the desire to trade at the beginning and end of the day as a function of overnight return volatility nyse data from 1933 88 indicate that closing volume is positively related to expected overnight volatility while volume at the open is positively related to both expected and unexpected volatility from the previous night we interpret the symmetric response of trading at the open and the close to expected volatility as being due to investor heterogeneities in the ability to bear risk when the market is closed this desire of investors to trade prior to market closings indicates a cost of mandating marketwide circuit breakers

let the good times roll the economic expectations of u s voters increasingly the concept of expectation is utilized to explain political choices with voters being depicted as prospective rather than retrospective in their orientations this paper tests competing theories of economic expectations forecasts with data from consumer surveys 1960 91 forecasts of inflation confirm the hypothesis of adaptive expectations but forecasts of general economic conditions do not nor do those forecasts conform to rational expectations instead voter forecasts of economic conditions are prone to a significant asymmetry while good economic times tend to foster optimism in an adaptive fashion bad times do not similarly feed pessimism instead they trigger a reverse forecast we explore this remarkable behavior in the light of psychological economics

trading mechanisms and stock returns an empirical investigation this paper examines the effects of the mechanism by which securities are traded on their price behavior we compare the behavior of open to open and close to close returns on nyse stocks given the differences in execution methods applied in the opening and closing transactions opening returns are found to exhibit greater dispersion greater deviations from normality and a more negative and significant autocorrelation pattern than closing returns we study the effects of the bid ask spread and the price adjustment process on the estimated return variances and covariances and discuss the associated biases we conclude that the trading mechanism has a significant effect on stock price behavior

home sweet home home bias and international diversification among individual investors abstract a striking feature of international portfolio investment is the extent to which equity portfolios are concentrated in the domestic market of the investor we investigate differences in home bias on an individual level by studying portfolios formed as a part of the new defined contribution pension plan in sweden we estimate the likelihood of home bias and use individuals demographic and socioeconomic features as explanatory variables our findings indicate that the likelihood of home bias is caused by both rational and irrational factors moreover we relate home bias to investors desire to hedge against inflation sophistication and overconfidence

voters information heterogeneity and the dynamics of aggregate economic expectations theory it is argued here that previous studies analyzing the formation of voters economic expectations overlook important subtleties found in a differentiated heterogeneous electorate since different segments of the electorate possess varying information capabilities it is asserted that they will form their prospective economic evaluations differently from one another hypotheses the impact of expectational electoral cycles news coverage of the economy reported by voters retrospective economic evaluations and personal financial expectations are hypothesized to have a differential impact on their economic expectations based on varying levels of information education among subsets of the electorate methods time series multiple regression analysis is conducted for the monthly period between january 1978 and december 1990 the empirical analysis involves testing for the properties of the statistical time series i e integration and cointegration as well as specification of an error correction mechanism ecm that captures long run statistical relationships in appropriate circumstances results these findings uncover electoral heterogeneity based on information education differences with respect to voters prospective economic evaluations specifically the information capabilities of voters is inversely related to their reliance on past retrospective sources of information when forming both egocentric and sociotropic economic expectations the main implication of this research is that the assumption of electoral homogeneity contained in previous longitudinal analyses of aggregate economic opinion formation provides misleading results that either overlook intra electoral variations introduce aggregation bias or possibly both

asymmetric price movements and borrowing constraints a rational expectations equilibrium model of crises contagion and confusion this study proposes a rational expectations equilibrium model of crises and contagion in an economy with information asymmetry and borrowing constraints consistent with empirical observations the model finds 1 crises can be caused by small shocks to fundamentals 2 market return distributions are asymmetric and 3 correlations among asset returns tend to increase during crashes the model also predicts 1 crises and contagion are likely to occur after small shocks in the intermediate price region 2 the skewness of asset price distributions increases with information asymmetry and borrowing constraints and 3 crises can spread through investor borrowing constraints

investor attention overconfidence and category learning abstract motivated by psychological evidence that attention is a scarce cognitive resource we model investors attention allocation in learning and study the effects of this on asset price dynamics we show that limited investor attention leads to category learning behavior i e investors tend to process more market and sector wide information than firm specific information this endogenous structure of information when combined with investor overconfidence generates important features observed in return comovement that are otherwise difficult to explain with standard rational expectations models our model also demonstrates new cross sectional implications for return predictability

what drives the swing voter in africa what makes african voters up for grabs existing approaches to the swing voter have several liabilities this article introduces a new measure enabling a more comprehensive assessment of swing voting including the differentiation between clientelistic and collective goods motivations the issue of swing voting is then brought to an environment where voters are rarely considered persuadable africa using a count model estimation technique and original survey data from ghana s critical 2008 elections the analysis challenges the near consensus in african politics on clientelism as the only electoral strategy when voters perceive politicians as providing collective developmental goods the efficacy of clientelism as a tool to win over voters is reduced many persuadable voters can also be won over by both clientelistic and collective goods thus contradicting the literature presenting these as mutually exclusive finally the analysis shows that incumbents do better when they provide collective goods even in highly clientelistic environments

what price accountability the lucas island model and the politics of monetary policy this paper develops a model of an electoral cycle in inflation and output based on rational inflation expectations and rational retrospective voting voters are heterogeneous and partially informed about aggregate macroeconomic variables they observe precisely how monetary policy stimulates their local economies but their observations of economic activity in other sectors are imprecise voters extract information about the incumbent policymaker s economic competence from cross sectoral spillover effects the incumbent has incentives to generate preelection monetary surprises that stimulate the local economies and generate cross sectoral spillover effects he thereby creates an impression of economic competence and furthers his reelection prospects his policy manipulations are the price of political accountability on a positive note the incumbent is more likely to survive voter scrutiny if he is more competent than the average political candidate

on the effects of barriers to international investment a simple model is presented in which it is costly for domestic investors to hold foreign assets the implications of the model for the composition of optimal portfolios at home and abroad are derived it is shown that all foreign assets with a beta larger than some beta plot on either one of two security market lines some foreign assets with a beta smaller than are not held by domestic investors even if their expected return is increased slightly while it is obviously not true that asset markets are completely segmented between countries there is evidence of barriers to international investment although reality seems to lie in that grey area between complete segmentation and no segmentation at all most international asset pricing models are concerned with the extreme case of no barriers to international investment no effort seems to have been made to study the effect on portfolio choice of such barriers which make it costly to hold foreign securities as opposed to domestic securities but which do not in general render international diversification so onerous that investors avoid foreign securities completely casual empiricism suggests that models without barriers to international investment should be suspect those models cannot explain why it appears that in every country investors on average hold more domestic securities than would be required if they held the world market portfolio 2 this paper constructs a model of international asset pricing in which there is a cost associated with holding either long or short risky foreign securities for the sake of simplicity in most of the paper we assume that while domestic investors face barriers to international investment foreign investors face no such barriers it turns out that nothing significant is lost with such an assumption the main conclusions of this paper for the case in which foreign investors face no barriers to international investment are 1 in the presence of barriers to international investment some risky foreign

the determinants of cross border equity flows abstract we explore a new panel data set on bilateral gross cross border equity flows between 14 countries 1989 1996 we show that a gravity model explains international transactions in financial assets at least as well as goods trade transactions gross transaction flows depend on market size in source and destination country as well as trading costs in which both information and the transaction technology play a role distance proxies some information costs and other variables explicitly represent information transmission an information asymmetry between domestic and foreign investors and the efficiency of transactions the geography of information is the main determinant of the pattern of international transactions while there is weak support in our data for the diversification motive once we control for the informational friction we broaden the scope of our results by presenting some evidence linking the results on equity transactions to equity holdings

endogenous asymmetric information and international equity home bias the effects of portfolio size and information costs equity home bias is one of the major puzzles in international finance this paper investigates the impact of asymmetric information on equity home bias in a rational expectation model where portfolio managers differ in their levels of initial portfolio size and information acquisition is endogenous the model characterizes the information acquisition and investment decisions made by each portfolio manager and the resulting equilibrium we find that portfolio managers with larger portfolio size acquire information about the foreign asset this is consistent with new evidence linking the degree of home bias across portfolio managers to portfolio size

animal spirits the effect of economic expectations on economic output the public is characterized as able forecasters of future economic performance they engage in rational expectations empirical evidence exists to bolster the claim this article considers the possibility that the public does more than predict economic output they may engage in a self fulfilling prophecy where belief about the future economy translates into personal financial behaviour e g consumption and investment that actually drives economic performance after controlling for rational expectations with elite forecasts leading indicators and past economic performance it is shown that between 5 and one third of the variance in economic output can be explained by prospective economic sentiment this result has broad implications for electoral behaviour research

international portfolios capital accumulation and foreign assets dynamics despite the liberalization of capital ows among oecd countries equity home bias remains sizable we depart from the two familiar explanations of equity home bias transaction costs that impede international diversi cation and terms of trade responses to supply shocks that provide risk sharing so that there is little incentive to hold diversi ed portfolios we show that the interaction of the following ingredients generates a realistic equity home bias capital accumulation shocks to the e ciency of physical investment as well as international trade in stocks and bonds in our model domestic stocks are used to hedge uctuations in local wage income terms of trade risk is hedged using bonds denominated in local goods and in foreign goods in contrast to related models the low level of international diversi cation does not depend on strongly countercyclical terms of trade the model also reproduces the cyclical dynamics of foreign asset positions and of international capital ows

economic expectations and voting behavior in united states house and senate elections past individual level studies of economic voting 1 have incorrectly operationalized the model they employ by using past oriented rather than future oriented questions and 2 have failed to examine the level of economic voting in united states senate elections using the 1978 national election study we show that economic voting exists in senate but not house elections presumably due to the differences in electoral context even when economic voting occurs however there is no guarantee that the public will influence the direction of macroeconomic policy

transitory price changes and price limit rules evidence from the tokyo stock exchange we compare the volatility of 24 hour returns computed from the opening and closing prices of a diverse sample of tokyo stock exchange tse stocks we find that volatility at the open is greater than volatility at the close only for the most actively traded tse stocks daytime and overnight return covariances suggest that the volatility patterns are explained by the effect of implicit bid ask spreads at the open and partial price adjustment at the close both of which are related to the intensity of trading our results challenge the view that open to open returns are more volatile than close to close returns for stocks in general and are consistent with the hypothesis that tse price limit rules have a significant impact on the dynamics of security prices

the political and economic origins of consumer confidence economic conditions the story usually goes influence consumer confidence which in turn influences both political evaluations and votes but we have little sense of the origins of consumer confidence itself it is generally assumed that monthly reports of the nation s level of consumer confidence respond to objective economic conditions we argue that politics is important for understanding consumer sentiment beyond what we know from economic conditions specifically we demonstrate a direct effect of political evaluations of the president s management of the economy the party of the president extraordinary political events and monetary policy as well as an indirect effect of media coverage of the economy on consumer sentiment after controlling for economic conditions when news coverage is positive citizens give favorable evaluations leading to more positive sentiment our findings suggest that understanding the political economy requires an emphasis on the causal effect of politics as well as economics

portfolio choice attention allocation and price comovement abstract this paper models the attention allocation of portfolio investors investors choose the composition of their information subject to an information flow constraint given their expected investment strategy in the next period which is to hold a diversified portfolio in equilibrium investors choose to observe one linear combination of asset payoffs as a private signal when investors use this private signal to update information about two assets changes in one asset affect both asset prices and may lead to asset price comovement the model also has implications for the transmission of volatility shocks between two assets

equity home bias a review essay this paper reviews the relatively more recent literature on equity home bias the empirical finding that people overinvest in domestic stocks relative to the optimal investment portfolio implied by the modern portfolio theory it reviews six broad classes of explanation of this puzzling phenomenon 1 hedging home risks 2 barriers to foreign investments 3 information asymmetries and 4 behavioral factors the consensus is that none of the explanations can account for the full extent of the bias by itself thus the home bias should be explained by a combination of rational and behavioral factors

china s financial linkages with asia and the global financial crisis abstract this paper presents empirical evidence on asset market linkages between china and asia and how these linkages have shifted during and after the global financial crisis of 2008 2009 we find only weak cross country linkages in longer term interest rates but much stronger linkages in equity markets this finding is consistent with the greater development and liberalization of equity markets relative to bond markets in china as well as increasing business and trade linkages in the region we also find that the strength of the correlation of equity prices changes between china and other asia countries increased markedly during the crisis and has remained high in recent years we attribute this development to greater attentiveness of international investors to china s role as a source and destination of equity finance during the crisis rather than to any greater financial deepening and liberalization as china did not implement any major policy measures during this period by contrast the transmission of u s equity returns to asian countries decreased after the crisis

the legal environment banks and long run economic growth this paper examines the relationship between the legal system and banlding development and traces this connection through to long run rates of per capita gdp growth capital stock growth and productivity growth the data indicate that countries where the legal system 1 emphasizes creditor rights and 2 rigorously enforces contracts have better developed banks than countries where laws do not give a high priority to creditors and where enforcement is lax furtherrnore the exogenous component of banking development the component defined by the legal environment is positively and robustly associated with per capita growth physical capital accumulation and productivity growth this paper addresses two questions first do crosscountry differences in the legal rights of creditors the efficiency of contract enforcement and the origin of the legal system explain cross country differences in the level of banking development second do better developed banks cause faster economic development that is is the component of banking development defined by the legal environment positively associated with long run rates of economic growth capital accumulation and productivity growth examining the relationship between the legal system and banking development is valuable irrespective of issues associated with long run growth first banks may influence the level of income per capita and the magnitude of cyclical fluctuations bernanke and gertler 1989 1990 second many economists stress that understanding the evolution of legal and financial systems is essential for understanding economic development north 1981 engerman and sokoloff 1996 consequently quantitative information on the relationship between the legal environment and banks will improve our understanding of business cycles and the process of economic development furthermore examining the causal links between banks and economic growth has both conceptual and policy implications on the conceptual front a long literature debates the importance of banks in economic development starting as early as bagehot 1873 economists have argued that better banks banks that are better at identifying creditworthy firms mobilizing savings pooling risks and facilitating transactions

information immobility and the home bias puzzle many argue that home bias arises because home investors can predict home asset payoffs more accurately than foreigners can but why does global information access not eliminate this asymmetry we model investors endowed with a small home information advantage who choose what information to learn before they invest surprisingly even when home investors can learn what foreigners know they choose not to investors profit more from knowing information others do not know learning amplifies information asymmetry the model matches patterns of local and industry bias foreign investments portfolio outperformance and asset prices finally we propose new avenues for empirical research

imperfect financial integration and asymmetric information competing explanations of the home bias puzzle this paper shows that imperfect financial integration and informational asymmetries are not competing theories but rather complementary ideas to a single explanation of the home bias puzzle we develop a rational expectations model of asset prices with investors that face informational constraints and find that informational advantages arise endogenously as a response to small financial frictions we also present empirical evidence that i international financial frictions are correlated to observed patterns of us investors attention and that ii the attention us investors allocate to foreign stocks helps explain home bias towards those countries even after controlling for financial integration levels ce memoire montre que l integration financiere imparfaite et l information asymetrique ne sont pas des theories concurrentes mais plutot des idees complementaires a l interieur d une resolution unifiee de l enigme du biais en faveur du marche domestique on developpe un modele d anticipations rationnelles des prix des actifs face a des investisseurs confrontes a des contraintes informationnelles et on decouvre que les avantages informationnels emergent de maniere endogene en reponse a de petites frictions financieres on montre empiriquement que i les frictions financieres internationales sont co reliees aux patterns d attention observes des investisseurs des etats unis et que ii l attention portee par les investisseurs americains aux marches financiers etrangers aide a expliquer le biais en faveur du marche domestique de ces pays meme apres avoir pris en compte les niveaux d integration financiere

home bias at the fund level this paper presents new stylized facts on the distribution of the home bias at the fund level we find i a large heterogeneity in the degree of home bias across mutual funds ii a positive correlation between the size of funds and home bias and iii a positive correlation between the size of funds the number of foreign countries and the number of sectors in which they invest these facts constitute a challenge for existing theories this abstract was borrowed from another version of this item

international investment restrictions and closed end country fund prices some closed end country funds trade at large premiums relative to their net asset values this paper examines whether international investment restrictions raise country fund price net asset value ratios by segmenting international capital markets we test whether a relation exists between announcements of changes in investment restrictions and changes in these ratios using weekly data from may 1981 to january 1989 the results provide evidence that some foreign markets are at least partially segmented from the u s capital market

endogenous acquisition of information and the equity home bias this paper investigates the extent to which differences in information costs can explain the equity home bias puzzle in a model where information costs are higher for the foreign asset than for the home asset i show that if cost functions are convex and the assets have identical return characteristics the expected size of the home bias in terms of differences in expected demands is positive and increasing in expected excess returns and risk but decreasing in risk aversion however a calibration to us data suggests that information costs can explain only a small fraction of the observed home bias

a rational explanation for home country bias abstract while modern portfolio theory predicts that investors should diversify across international markets corporate equity is essentially held by domestic investors french and poterba 1991 french k poterba j 1991 investor diversification and international equity markets american economic review 81 222 226 suggest that in order for this bias to be justified investors must hold optimistic expectations about their domestic markets and pessimistic expectations about their foreign markets tesar and werner 1995 tesar l l werner i m 1995 home bias and high turnover journal of international money and finance 14 467 492 find existing explanations for the home equity bias unsatisfactory and conclude that the issue poses a challenge for portfolio theory we develop a model that incorporates both the foregone gains from diversification and the informational constraints of international investing and shows that home equity bias is consistent with rational mean variance portfolio choice specifically we prove that the nature of estimation risk in international markets can be responsible for this phenomenon we show that when the cross market variability in the estimation errors of international markets means far exceeds the cross market variability in the means themselves domestic dedication dominates international diversification an examination of 11 international markets returns over the last 25 years from the perspective of german japanese and us investors provides evidence consistent with this explanation

the determinants of international investment and attention allocation using internet search query data abstract this paper explores the joint determination of home bias and attention allocation we overcome the typical challenge associated with evaluating attention allocation theories by using a new internet search query dataset to measure how much information investors decide to process employing an instrumental variables approach we find empirical evidence of a two way causality between home bias and attention our estimates suggest that if all countries were to receive the same level of attention as the u s then the average home bias by u s investors would fall from 85 2 to 57 3

the puzzling evolution of the home bias information processing and financial openness abstract this paper explains the home equity bias and its puzzling evolution in a model where investors face an information constraint and have an initial local informational advantage after financial liberalization local investors have a magnified informational advantage since information processed under autarky remains useful after liberalization a gradual shift towards foreign assets occurs as the relevance of autarkic information declines over time in the long run home bias remains large due to the interaction between information and portfolio choices empirical evidence supports the main predictions of our model namely that bias increases with information capacity and decreases with financial openness

implications of rational inattention abstract a constraint that actions can depend on observations only through a communication channel with finite shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems the resulting theory looks enough like familiar dynamic rational expectations theories to suggest that it might be useful and practical while the implications for policy are different enough to be interesting

economic voting and the symbolic politics argument a reinterpretation and synthesis economic voting is generally regarded as a straightforward political demand for the amelioration of economic grievances this assumption about motives underlies the implicit theories of politicians and the imputations of interests to voters in aggregate time series models several recent articles have argued that voting is not self interested but a manifestation of symbolic preferences at the level of the collectivity this article places the dispute between personal and collective decision referents into the broader perspective of a multi stage model of information processing and decision making personal and collective decision referents are shown to define the poles of a continuum and several hypotheses are derived to predict the relative weights assigned to each in the voter s calculus the model is used in analyses of both the public s evaluations of incumbent economic management and economic voting in different electoral arenas by varying issue publics designed to maximize comparability with aggregate studies this research includes both objective and subjective measures of economic conditions and indexes changes in personal conditions over time from panel data
