country portfolios under global imbalances abstract this paper studies the composition of country portfolios under global imbalances when countries are identical the optimal portfolio is fully diversified which reflects the cross country symmetric self hedging lucas 1982 assuming a structural country asymmetry in patience we construct a model of portfolio choices that features persistent non zero net foreign assets nfa because the latter opens a gap between gnp and gdp we found that an asymmetric hedging of net portfolio returns emerges in addition to the otherwise only lucas symmetric self hedging in shaping the gross country portfolios which implies a short long position of the local asset in the debtor creditor country the resulting portfolio is home biased we calibrate our model to the u s and china data over 1999 2017 and show that it matches the portfolio data for countries with unbalanced net external positions well

home bias and cross border taxation abstract the relationship between cross border taxation and free float home bias is examined this explicitly recognizes that insider shares are unavailable to foreigners other important explanations for home bias information asymmetry behavioural and governance issues are controlled when examining the impact of cross border tax variables in our sample of countries about sixty percent eighty percent withhold taxes on realized capital gains dividends of foreign investors and about thirty percent of the mature economies provide imputation of taxes paid on dividend income by domestic corporations dividend imputation is a statistically significant impediment to cross border equity flows a tax credit variable for foreign taxes paid on dividends is constructed and found to be statistically significant in reducing home bias a relatively high foreign tax rate that cannot be offset by tax credits is found to significantly increase home bias these results hold for float adjusted home bias and traditional international portfolio home bias

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

investment allocation decisions home bias and the mandatory ifrs adoption abstract we examine the familiarity hypothesis of home bias by studying how foreign ownership of swedish firms is affected by the mandatory adoption of ifrs we decompose foreign investors into institutional and non institutional investors foreign investors are further decomposed into eu ifrs adopting countries and non eu residents non ifrs adopting countries we analyse the equity investments of these foreign investor groups in sweden during the period of 2001 2007 we find that after the mandatory adoption of ifrs foreign ownership owners from countries that adopted ifrs and particularly those from the eu increased these effects are particularly strong in small firms foreign institutional investors increased their ownership stake after the mandatory ifrs adoption whereas foreign non institutional investments were not affected significantly by the ifrs adoption in contrast to ownership from non adopting countries ownership from the eu increased in firms with both more and less tangible assets similarly foreign ownership from the eu increased in firms with both concentrated ownership and dispersed ownership after the adoption because sweden has already had strict legal enforcement and a low level of earnings management prior to the adoption our results suggest that increased foreign ownership is due to better abilities to compare firms rather than an improved quality

what is the economic cost of the investment home bias overinvesting domestically is well known as an investment home bias ihb we define an economic home bias ehb whereby the ihb measures the investment weights and the ehb measures the economic cost induced by the ihb we may have a large ihb and a negligible ehb with the increase in the average correlation between foreign markets from 0 4 for the decade ending in 1988 to about 0 9 for more recent decades the u s ehb is becoming negligible despite the domestic investment of 77 5 since 2009 the correlations have decreased indicating that the hb puzzle is emerging once again

betting your favorite to win costly reluctance to hedge desired outcomes we examined whether people reduce the impact of negative outcomes through emotional hedging betting against the occurrence of desired outcomes we found substantial reluctance to bet against the success of preferred u s presidential candidates and major league baseball national football league national collegiate athletic association ncaa basketball and ncaa hockey teams this reluctance was not attributable to optimism or a general aversion to hedging reluctance to hedge desired outcomes stemmed from identity signaling a desire to preserve an important aspect of the bettor s identity reluctance to hedge occurred when the diagnostic cost of the negative self signal that hedging would produce outweighed the pecuniary rewards associated with hedging participants readily accepted hedges and pure gambles with no diagnostic costs they also more readily accepted hedges with diagnostic costs when the pecuniary rewards associated with those hedges were greater reluctance to hedge identity relevant out

the effectiveness of international diversification whole markets versus sectors a hedging approach is used to examine the effect of sectoral factors on the effectiveness of international diversification by using data covering seven countries and various sectors we find that international diversification is more effective when assets from developed markets only are used and when multiasset portfolios are used instead two asset portfolios the results also reveal that international diversification across whole markets is more effective than diversification across sectors these results reflect the pattern of return correlation

international portfolio nondiversification and exchange rate variability abstract incomplete international portfolio diversification is implied by an equilibrium models of exchange rates with nontraded goods the model can also explain the greater correlation between consumption and income within a country than between consumption across countries nontraded goods make more stringent the elasticity conditions required to explain exchange rate variability resulting from current productivity disturbances though not from disturbances to fiscal policies or the prospective return to investment the model is also consistent with international real interest rate differentials changes over time in the current account and relative wealth across nations and observed time series properties of exchange rates

home bias in equity portfolios inflation hedging and international capital market equilibrium we test whether the home bias in equity portfolios is caused by investors trying to hedge inflation risk the empirical evidence is consistent with this motive only if investors have very high levels of risk tolerance and equity returns are negatively correlated with domestic inflation we then develop a model of international portfolio choice and equity market equilibrium that integrates inflation risk and deadweight costs using this model we estimate the levels of costs required to generate the observed home bias in portfolios consistent with different levels of risk aversion for a level of risk aversion consistent with standard estimates of the domestic equity market risk premium these costs are about a few percent per annum greater than observable costs such as withholding taxes thus the home bias cannot be explained by either inflation hedging or direct observable costs of international investment unless investors have very low levels of risk aversion article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

revisiting the home bias puzzle downside equity risk deviations from normality in financial return series have led to the development of alternative portfolio selection models one such model is the downside risk model whereby the investor maximizes his return given a downside risk constraint in this paper we empirically observe the international equity allocation for the downside risk investor using nine international markets returns over the last 34 years the results hold for both daily and monthly data and also from an international perspective due to greater downside risk investors may think globally but instead act locally the model s results therefore provide an alternative view of the home bias puzzle

what determines mutual fund trading in foreign stocks abstract we examine the portfolio rebalancing measured by the equity churn rate of mutual funds from 29 countries based on annual stockholdings over the 1999 2006 period we find that funds more often trade the stocks of companies located in countries with higher degree of information asymmetry and are less familiar to fund managers after we control for the effects of stock market development and investor protection consistent with the behavioral bias fund managers more often rebalance stocks in foreign markets that perform well this bias is exacerbated when fund managers are less familiar with and less informed about those markets

the reality of stock market jumps diversification abstract we propose a non parametric procedure for estimating systemic co jumps and independent idiosyncratic jumps for 35 stock markets and study news associated with these jumps as reported in factiva and bloomberg from 1988 to 2014 our results suggest that it is important to distinguish between systemic co jumps and idiosyncratic jumps we find both types of jumps have important implications for home bias investors while idiosyncratic jumps have economically significant impact on portfolio weights for emerging markets our news analysis suggests systemic jumps are typically caused by currency crises sectoral failure liquidity issues and deteriorating economic climate while idiosyncratic jumps are usually caused by political unrest currency instability and large firm effects on small economies in fact many of the idiosyncratic jumps share the same origin although different stock markets experienced the impact differently at different times

do trade costs in goods market lead to home bias in equities abstract two of the main puzzles in international economics are the consumption and the portfolio home biases we solve for international equity portfolios in a two country two good stochastic equilibrium model with trade costs in goods markets we show that introducing trade costs as suggested by obstfeld and rogoff obstfeld m rogoff k 2000a the six major puzzles in international macroeconomics is there a common cause nber macroeconomics annual 15 is not sufficient to explain these two puzzles simultaneously on the contrary we find that trade costs create a foreign bias in portfolios for reasonable parameter values this result is robust to the addition of non tradable goods for standard calibrations of the preferences

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

race and charitable church activity i introduction faith based organizations provide social services for more than 70 million americans annually johnson tompkins and webb 2002 of the more than 350 000 congregations in the country more than 85 support some type of social service activity solomon 2003 biddle 1992 estimates that each year congregations spend 24 billion dollars on philanthropic activities these actions have gained new relevance for policymakers as the availability of public funding for charitable church activity has dramatically increased in the past decade starting with the charitable choice provision of the 1996 welfare reform law and continuing with the creation of centers for faith based and community initiatives located in 11 different federal agencies policymakers have instituted a devolution of federal funds intended to provide community services in 2005 more than 2 1 billion dollars in government grants were awarded to religious organizations by federal agencies office of the press secretary 2006 1 some observers fear that this policy trend will encourage racial discrimination by congregations leonard 2002 as bartkowski and regis 2003 write congregational definitions of legitimate social problems that members care about are in actuality influenced by various considerations among them racialized perceptions of welfare recipients past studies by economists have postulated but not substantiated that churchgoers warrant special consideration as individuals whose actions are sensitive to community demographics e g alesina and la ferrara 2000 gruber 2005 alternately some policymakers have championed faith based organizations because they are not likely to display sensitivity to community demographics when providing services as president bush stated in a speech in 2002 faith based charities work daily miracles because above all they recognize the dignity of every citizen and the possibilities of every life office of the press secretary 2002 john diiulio the former director of the white house office of faith based and community initiatives argued for charitable choice by saying government at all levels blatantly denies the equal protection of the laws to low income urban african american and latino children and families who depend disproportionately on faith based organizations for both basic life necessities and the delivery of specific social welfare benefits diiulio 2002 there is also noneconomic research consistent with this view e g billiet 1995 johnson 1977 the goal of this article was to examine whether congregations are affected by the racial composition of the local community when deciding whether and how much charitable activity to provide exploring this relationship is valuable not only because it addresses a key policy debate but also because it contributes to existing economic work on diversity and redistribution much prior work on socioeconomic conditions and tastes for redistribution relies on hypothetical questions asked to respondents in the general social survey or in gallop polls examples include alesina and la ferrara 2005b luttmer 2001 fong 2001 this article examines how a community s racial composition affects actual charitable expenditures studying actual charitable activities will be valuable if individuals stated preferences are different from their actual preferences or if stated preferences are sensitive to the wording of a question as is the case in alesina and la ferrara 2005b to investigate the effect of race on charitable church activity we compare how racially homogeneous congregations respond to the community s racial composition relative to other congregations several factors support this approach first members of homogeneous congregations have ostensibly taken race into account when selecting a congregation to attend consequently these congregations may be especially likely to display sensitivity to a community s racial composition when providing charitable services

social interaction and stock market participation we propose that stock market participation is influenced by social interaction in our model any given social investor finds the market more attractive when more of his peers participate we test this theory using data from the health and retirement study and find that social households those who interact with their neighbors or attend church are substantially more likely to invest in the market than non social households controlling for wealth race education and risk tolerance moreover consistent with a peer effects story the impact of sociability is stronger in states where stock market participation rates are higher

model misspecification and underdiversification in this paper we study intertemporal portfolio choice when an investor accounts explicitly for model misspecification we develop a framework that allows for ambiguity about not just the joint distribution of returns for all stocks in the portfolio but also for different levels of ambiguity for the marginal distribution of returns for any subset of these stocks we find that when the overall ambiguity about the joint distribution of returns is high then small differences in ambiguity for the marginal return distribution will result in a portfolio that is significantly underdiversified relative to the standard mean variance portfolio

financial returns and efficiency as seen by an artificial technical analyst abstract we introduce trading rules which are selected by an artificially intelligent agent who learns from experience an artificial technical analyst these rules restrict the data mining concerns associated with the use of simple technical trading rules as model evaluation devices and are good at recognising subtle regularities in return processes the relationship between the efficiency of financial markets and the efficacy of technical analysis is investigated and it is shown that the artificial technical analyst can be used to provide a quantitative measure of market efficiency we estimate this measure on the djia daily index from 1962 to 1986 and draw implications for the optimal behaviour of certain classes of investors it is also shown that the structure of technical trading rules commonly used is consistent with utility maximisation for risk neutral agents and in a myopic sense even for risk averse agents

institutional differences and international private debt markets a test using mandatory ifrs adoption institutional differences between countries result in additional information risks between borrowers and lenders in cross border private loans this study examines the effect of these information risks on the structure of optimal debt contracts in international cross border versus domestic private debt markets using mandatory ifrs adoption as an indicator for institutional changes that reduced differences between countries i compare attributes of international versus domestic loans before and after ifrs adoption i find that in the pre ifrs period international loans are associated with a higher credit spread a weaker relationship between the bank and the borrower a more diffuse loan syndicate and less reliance on accounting based covenants than domestic loans these results are consistent with incremental information risks in international debt markets that make it more costly for lenders to screen and monitor borrower credit quality resulting in a more arm s length relationship between borrowers and lenders many of these associations attenuate after ifrs adoption suggesting that the pre ifrs differences in contract terms are driven by incremental information risks related to institutional differences between countries my findings imply that incremental information risks result in a different optimal contract in international debt contracts compared to domestic debt contracts

integration vs segmentation in the canadian stock market this paper examines the issue of integration versus segmentation of the canadian equity market relative to a global north american market we compare the international and domestic versions of the capm and find that integration or the mean variance efficiency of the global market index is rejected by the data segmentation is the preferred model based on a maximum likelihood procedure correcting for thin trading we further divide the sample into securities that are interlisted in canada and the u s and those that are not integration is rejected for both groups which indicates that the source of segmentation can be traced to legal barriers based on the nationality of issuing firms empirical studies of international capital markets have left the issue of segmentation versus integration largely unresolved yet the question of national or international pricing of assets has crucial implications for financial decisions if national stock markets are segmented then international portfolios should display superior risk adjusted performance because some of the priced domestic systematic risk is diversifiable also with segmentation many irrelevance propositions for corporate financial strategy break down home firms face optimal hedging decisions as well as optimal foreign versus home borrowing decisions finally criteria for capital budgeting decisions will be quite different under national and international pricing the purpose of this paper is to shed some light on this integration versus segmentation question for the canadian equity market vis a vis a global north american market in this paper integration is defined2 as a situation where investors earn the same risk adjusted expected return on similar financial instruments in different national markets the key problem of course is the pricing

how many stocks make a diversified portfolio we show that a well diversified portfolio of randomly chosen stocks must include at least 30 stocks for a borrowing investor and 40 stocks for a lending investor this contradicts the widely accepted notion that the benefits of diversification are virtually exhausted when a portfolio contains approximately 10 stocks we also contrast our result with the levels of diversification found in studies of individuals portfolios

the impact of global equity offerings this article examines the impact of u s firms issuing equity in multiple markets we compare the stock price reactions to announcements of global equity offers to a control group of issues offered exclusively in the domestic u s market all else equal the adverse price reaction that typically accompanies equity issuance is reduced by 0 8 percent when some shares are sold abroad the overall evidence suggests global offers are effective in expanding demand and reducing the price pressure effects associated with share issuance the benefits of global offers appear to be associated with an increase in the number of foreign shareholders the search for new capital markets and lower costs of capital is an ongoing search for most firms in recent years the number of u s firms issuing common equity in international markets has increased significantly in 1985 u s firms raised 89 million through follow on equity offers in foreign markets and this amount increased to 18 915 million in 1995 a greater than 200 fold increase in nominal terms this paper focuses on follow on global equity issues by u s firms and attempts to assess why firms widely acknowledged to have access to broad and deep domestic capital markets increasingly seek to raise equity abroad the global equity offerings we examine involve a simultaneous sale of common equity at the same offer price in the u s market and one or more international markets we examine the characteristics of the issuers and issues and investigate to what extent the wider distribution of shares affects the pricing and costs of these issues our main line of inquiry examines whether the distribution of shares to multiple markets results in a higher offer price for equity shares than would be obtained had the shares been sold exclusively in the u s market domes

home bias in open economy financial macroeconomics standard theory would predict that investors hold a well diversified portfolio of equities across the world but despite the process of financial globalization investors still hold a disproportionate share of local equities in their portfolio the equity home bias french and poterba 1991 we review the various explanations of this puzzling phenomenon in the context of recent developments in macroeconomic modelling that have allowed to incorporate sophisticated international portfolio choices in standard two country general equilibrium models we refer to this literature as open economy financial macroeconomics we focus on three broad classes of explanations i hedging motives in frictionless financial markets real exchange rate and non tradable income risk ii asset trade costs in international financial markets such as transaction costs differences in tax treatments between national and foreign assets iii informational frictions and behavioural biases these recent developments raise the need for new portfolio facts beyond the equity home bias and we will present some new evidence on cross border asset holdings across different types of assets equities bonds and bank lending we also present some new micro data on institutional holdings of equity at the fund level these data should inform macroeconomic modelling of the open economy and a growing literature of models of delegated investment

financial education investor protection and international portfolio diversification abstract this paper investigates the effect of financial education on foreign portfolio investment we show that higher investor financial education fosters international diversification and that its role is particularly pronounced where information problems and monitoring costs are likely to be more severe that is in countries where protection of minority shareholders rights is weaker we interpret this evidence as supportive of the conjecture that financial education lessens the informational constraints binding foreign investors

confidence in the familiar an international perspective one striking feature of intemrnational portfolio investment is the extent to which equity portfolios are concentrated in the domestic equity market of the investor the home bias puzzle i examine the role of investors perception of foreign investment risk on their portfolio choices the expected retumrns and risk of foreign investment are specified through an asset pricing model with the home portfolio being the benchmark asset pastor s 2000 domestic capm the model serves as a reference point around which investors can center their prior beliefs i focus on investors prior beliefs that are consistent with the literature on confidence in the familiar foreign equities in terms of both expected returns and risk being viewed less favorably than domestic equities these prior beliefs are then combined with the data on g7 equities and the revised beliefs are used to obtain the global optimal asset allocation to hold predominantly domestic equities each g7 investor has to believe that the risk of foreign investment is several times higher than the actual risk the home bias is more of a puzzle for a u s investor during the 1970s specifying investors prior beliefs around the world capm does not help resolve the puzzle

the ability of global stock exchange mechanisms to mitigate home bias evidence from euronext this paper examines the effects on equity home bias of two mechanisms adopted by euronext when it was formed by the merger of four european countries stock exchanges in 2002 the two structural mechanisms are the integration of trading platforms across the four predecessor exchanges and the creation of named segments of the integrated exchange on which firms could voluntarily list by precommitting to enhanced disclosure and transparency employing a difference in differences research design using other european union companies as a control group we document that the integration of the euronext market was associated with a reduction in home bias for firms listed on the named segments of the euronext exchange but not for the nonsegment euronext firms our results suggest that the reduction in transaction costs from the integration of the trading platforms did not make the nonsegment euronext firms more attractive to the specific investors for whom the transaction costs were reduced on the other hand the decrease in information costs due to the precommitments to enhanced transparency made the segment firms more attractive to all categories of foreign investors consistent with the information costs hypothesis this paper was accepted by mary barth accounting

the only game in town stock price consequences of local bias abstract theory suggests that in the presence of local bias the price of a stock should be decreasing in the ratio of the aggregate book value of firms in its region to the aggregate risk tolerance of investors in its region using data on u s states and census regions we find clear cut support for this proposition most of the variation in the ratio of interest comes from differences across regions in aggregate book value per capita regions with low population density e g the deep south are home to relatively few firms per capita which leads to higher stock prices via an only game in town effect

the euro and corporate valuations in this paper we study the changes in corporate valuations induced by the adoption of the euro as the common currency in europe we use corporate level data from seventeen european countries of which eleven adopted the euro we show that the introduction of the euro has increased tobin s q ratios by 17 1 in the euro area countries that previously had weak currencies part of the increase in corporate valuations is explained by the decrease in interest rates and by the decrease in the cost of equity the increases in tobin s q are larger for firms that would be harmed by currency devaluations the author 2008 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oxfordjournals org oxford university press

asset pricing in partially segmented markets evidence from the finnish market this paper analyzes asset pricing in a partially segmented market where citizens of a small country are allowed to hold only their domestic securities whereas the rest of the investors foreigners are essentially allowed to hold all securities in this market setting it may occur that the citizens of the small country are willing to pay less for their domestic securities than are the foreign investors the paper derives equilibrium required rates of return for different investors in this market setting which perfectly occurred in finland and tests this equilibrium model using data from the finnish stock market empirical results are consistent with the hypotheses derived from the model several studies see e g solnik 1974a and grauer and hakansson 1987 have shown that investors should diversify internationally as by so doing they can reduce the risk of their portfolio without lowering the expected return this implies that if the citizens of a certain country are by legal restrictions prohibited from holding foreign securities they may require a higher rate of return on the domestic securities than the foreign investors do this may happen because the domestic investors cannot diversify away the specific country risk in the same way that the foreign investors can thus if we could observe the prices which the foreign and domestic investors are willing to pay for these domestic securities we would expect them to differ because of this diversification effect the finnish law prohibited finnish investors from investing in foreign securities until 1986 while simultaneously allowing foreign investors to own up to 20 of the shares of any finnish company moreover since 1984 the helsinki stock exchange hse has separately quoted the prices for the unrestricted shares which can be owned both by foreign and domestic investors and for the restricted shares owned solely by domestic investors thus the market setting depicted in the previous paragraph occurred perfectly in finland during the years 1984 and 1985 in this paper our objective is to develop and test an asset pricing model which takes into account the legal restrictions in the finnish stock market in section i we specify the market structure in the finnish stock market in more detail by explaining the relevant legal restrictions affecting the market we also present some descriptive statistics on the prices of the restricted and the unrestricted on

partially segmented international capital markets and international capital budgeting abstract evidence suggests that international capital markets are neither fully integrated nor completely segmented there is however currently no general method available for computing the required return on corporate investments in such capital markets this paper uses a model of partially integrated international capital markets to derive optimal international capital budgeting rules we show how capital budgeting rules depend on the level of investor costs to cross border investment both directly and also indirectly through the portfolio specialization they induce we explain how required returns differ for different companies raising capital in such markets and how these costs of capital may be estimated we also explain how these differences in required returns can be consistent with general equilibrium and the effect they have on incentives for foreign direct investment

is full banking integration desirable abstract we analyze the links between banking integration and economic development for a sample of oecd countries we measure banking integration considering indicators that merge not only openness but also connectedness with other banking systems we plug these indicators into income regressions also controlling for other relevant variables considered by the literature in contrast to previous initiatives this second stage explicitly takes into account the differing levels of economic development of the countries in our sample since the benefits of enhanced banking integration might not be generalizable to this end we implement quantile regression also considering the presence of endogenous regressors results show that bank connectedness is more important for economic development than bank openness but the combined effect i e banking integration overall is positive and significant the quantile regression models used in the second stage show that the effects are stronger for the poorest economies

does home bias affect firm value evidence from holdings of mutual funds worldwide this study finds strong evidence that home bias affects firm valuation at both country and firm levels at the country level increasing the bias of domestic investors toward home equity lowers the market valuation of home equity at the firm level firm value increases as the compositions of local equities held by domestic and foreign investors tend toward the firms global market capitalization weights but decreases as their weights deviate from global weights overall the evidence is consistent with the optimal global risk sharing hypothesis that the greater risk sharing between domestic and foreign investors in international capital markets reduces the cost of capital and hence enhances market valuation

equilibrium exchange rate hedging we assume a world like the one that gives the capital asset pricing model but with many goods and many countries we assume that investors in a given country have homothetic utility functions with the same weights and a currency that has a sure endof period value using a price index with those weights siegel s paradox derived from jensen s inequality makes investors want a positive amount of exchange risk when average risk tolerance is the same across countries every investor will hold the same mix of market risk through the world market portfolio of all assets and exchange risk in a diversified basket of foreign currencies in fact the ratio of exchange risk to market risk is equal to the average investor s risk tolerance we can write the ratio of exchange risk to market risk and the fraction of the market s exchange risk that investors hedge as depending on an average of world market risk premia an average of world market volatilities and an average of exchange rate volatilities the weights in these averages are the same as the weights of the different countries in the currency basket given these averages the ratio and the fraction hedged will not depend directly on exchange rate means or covariances in equilibrium we can use the ratio of exchange risk to market risk to measure average risk tolerance in this model risk tolerance is observable

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

home asset preference and productivity shocks abstract this paper presents sufficient conditions for the domestic investor consumer to hold in equilibrium a disproportionate share of domestic assets the analysis is carried out in a general equilibrium framework of products and assets markets when the source of the uncertainty is productivity shocks in the nontraded goods industries in the asset markets we allow trade in instruments with a payoff which is not necessarily positively correlated with the price of the consumption good as the instruments considered in the existing literature consequently in our analysis in contrast to the existing literature hedging against price uncertainty is neither necessary nor sufficient for home asset preference

the distance effect in banking and trade abstract the empirical gravity literature finds geographical distance to be a large and growing obstacle to trade contradicting the popular notion that globalization heralds the end of geography this distance puzzle disappears however when measuring the effect of cross border distance relative to that of domestic distance yotov 2012 we uncover the same result for banking when comparing cross border positions with domestic credit using the most extensive dataset on global bank linkages between countries the role of distance remains substantial for trade as well as for banking where transport cost is immaterial pointing to the role of information frictions as a common driver a second contribution is to show that the forces of globalization are also evident in other less prominent parts of the gravity framework

gains from international diversification 1968 85 returns on portfolios of stocks and bonds this paper applies the multi period investment model to a universe of international securities on the basis of the simple probability assessment approach our principal findings are 1 the gains from including non u s asset categories in the universe were remarkably large in some cases statistically significant especially for the highly risk averse strategies 2 the gains from removing the no leverage constraint were more substantial than they were in the absence of non u s securities and 3 there is strong evidence of market segmentation in that the optimal levels of investment in u s securities were mostly zero in the presence of the non u s asset categories
