a note on foreigners trading and price effects across firms abstract we study the investment behavior of foreign investors in association with an equity market liberalization and find a strong link between foreigners trading and local market returns in the period following the liberalization net purchases by foreign investors induced a permanent increase in stock prices suggesting that local firms reduced their cost of equity capital we also find a strong link between a firm s fraction of foreign ownership and the magnitude of the cost reduction foreign investors seem to prefer large and well known firms and these firms realize the largest reduction in capital cost furthermore our analysis suggests that foreigners increase their net holding in firms that have recently performed well analyzing foreigners performance we find very little evidence of informed trading suggesting that risk sharing is the most plausible explanation for the reduction of the cost of equity capital

information acquisition and under diversification if an investor wants to form a portfolio of risky assets and can exert effort to collect information on the future value of these assets before he invests which assets should he learn about the best assets to acquire information about are ones the investor expects to hold but the assets the investor holds depend on the information he observes we build a framework to solve jointly for investment and information choices with general preferences and information cost functions although the optimal research strategies depend on preferences and costs the main result is that the investor who can first collect information systematically deviates from holding a diversified portfolio information acquisition can rationalize investing in a diversified fund and a concentrated set of assets an allocation often observed but usually deemed anomalous copyright wiley blackwell

nonstationarity in job search theory generally structural job search models are taken to be stationary in this paper models are examined in which every exogenous variable can cause nonstationarity for instance because its value is dependent on unemployment duration a general differential equation that describes the evolution of the reservation wage over time is derived as an empirical illustration a nonstationary structural model is estimated that focuses on the consequences of a downward shift in the level of benefits it appears that the elasticity of duration with respect to the level of benefits after the shift is much larger than the elasticity with respect to the level before the shift this paper examines the movement of a job seeking individual s reservation wage over time in a general nonstationary job search model also results concerning comparative dynamics of the reservation wage and the distribution of the duration of unemployment are derived as an empirical illustration a nonstationary structural model is estimated the nonstationarity originates from the decrease in the level of benefits when unemployment duration equals two years from the results some detailed policy recommendations can be deduced as one is able to distinguish the effect of a change in the level of benefits in the first two years of unemployment from the effect of a change in the level after that period recently the use of job search models for the analysis of unemployment duration has become widespread the reduced form approach in empirical studies see e g lancaster 1979 in which only the hazard of the duration distribution is estimated is gradually being replaced by a more structural approach the latter way of modelling is characterized by the explicit use in empirical analysis of the reservation wage equation as stated by the theory e g yoon 1981 lancaster and chesher 1983 lynch 1983 narendranathan and nickell 1985 and van den berg 1988 use the complete theoretical framework of job search theory to make inferences about search behaviour however the structural models used in these studies are stationary this implies that variables like unemployment benefits or the rate of arrival of job offers are assumed to be constant over the spell of unemployment which is often at variance with reality what is more various reduced form empirical studies indicate a significant durationdependence of the re employment probability which is generally interpreted as evidence in favour of the presence of nonstationarity see e g blau and robins 1986 kooreman and ridder 1983 lancaster 1979 and narendranathan nickell and stern 1985 consequently there is a need to model reservation wage movements over time based on a nonstationary theoretical framework

improving the labor market trade off between inflation and unemployment the work on the phillips curve has been predominantly empirical but policy intervention designed to decrease both inflation and unemployment requires a better theoretical understanding of the determinants of this relation this paper attempts to sketch out the basic labor market relationships that appear to the author to account largely for the phillips relation2 and then to consider the kinds of policy measures that this analysis suggests are relevant for moving the phillips curve the basic issue involved in the stability or instability of the phillips curve when the inflation rate is constant is explored with a simple model in the appendix the emphasis in this paper is on the atomistic operation of the labor market because it appears sufficient to generate the phillips relation but we do not deny that union bargaining and price dynamics may also be involved to some degree this paper concentrates on conceptual issues continuing research will be devoted to the statistical measurement of relationships

do institutional factors influence cross border portfolio equity flows new evidence from emerging markets abstract we exploit a proprietary database containing foreign trading data from 20 stock exchanges for the 2006 2018 period to expand the existing evidence on cross border equity flows towards emerging markets in particular after briefly assessing the relevance of push and pull factors we study whether explicit and implicit barriers to investment corporate governance standards and market structure features influence cross border equity inflows we find that pull factors are an important determinant of foreign inflows while push factors have a smaller influence more importantly we find that removing explicit barriers to investment and adopting stricter corporate governance practices has a long run positive relation with inflows conditional on push and pull factors removing information barriers also matters but relatively less market structure features have instead little influence on cross border flows towards emerging markets

central bank transparency and cross border banking abstract we analyze the effect of central bank transparency on cross border bank activities based on a panel gravity model for cross border bank claims for 21 home and 47 destination countries from 1998 to 2010 we find strong empirical evidence that a rise in central bank transparency in the destination country on average increases cross border claims using interaction models we find that the positive effect of central bank transparency on cross border claims is only significant if the central bank is politically independent and operates in a stable economic environment central bank transparency and credibility are thus considered complements by banks investing abroad

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

converging or diverging a comparative analysis of trends in contingent employment practice in europe over a decade this paper makes a unique contribution to the hrm convergence divergence debate by examining whether organisations operating in europe over the 10 year time period preceding 2000 are converging in their adoption of contingent employment practice the susceptibility of contingent employment practice to both convergent and divergent pressures acts as a useful analytical lens data are drawn from organisations operating in germany spain sweden the netherlands and the uk in 1991 2918 organisations 1995 2048 organisations and 2000 1555 organisations the results suggest that convergence is limited by the institutional embeddedness of organisations

search theoretic models of the labor market a survey we survey the literature on search theoretic models of the labor market we show how this approach addresses many issues including the following why do workers sometimes choose to remain unemployed what determines the lengths of employment and unemployment spells how can there simultaneously exist unemployed workers and unfilled vacancies what determines aggregate unemployment and vacancies how can homogeneous workers earn different wages what are the tradeoffs firms face from different wages how do wages and turnover interact what determines efficient turnover we discuss various modeling choices concerning wage determination and the meeting process including recent models of directed search

what makes management style similar and distinct across borders growth experience and culture in korean and japanese firms using a survey database of japanese and korean firms we compare the styles of two asian business systems with a japanese rather than an american mirror there are substantial differences in the two country styles we introduce two sources of convergence firm size as measured by sales and globalization as measured by export ratio and find that both of these factors reduce the difference with globalization the more significant of the two

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

home bias in global bond and equity markets the role of real exchange rate volatility abstract this paper focuses on the role of real exchange rate volatility as a driver of portfolio home bias and in particular as an explanation for differences in home bias across financial assets we present a markowitz type portfolio selection model in which real exchange rate volatility induces a bias towards domestic financial assets as well as a stronger home bias for assets with low local currency return volatility we find empirical support in favour of this hypothesis for a broad set of industrialized and emerging market countries not only is real exchange rate volatility an important factor behind bilateral portfolio home bias but we find that a reduction of monthly real exchange rate volatility from its sample mean to zero reduces bond home bias by up to 60 percentage points while it reduces equity home bias by only 20 percentage points

costly buyer search in laboratory markets with seller advertising in this experiment sellers simultaneously choose prices and advertising strategies buyers either purchase at an advertised price or search sequentially for other prices in the unique symmetric equilibrium sellers charge a high unadvertised price or advertise a price chosen from a lower interval increases in search or advertising costs raise equilibrium prices and affect equilibrium advertising intensity empirical results are consistent with most comparative static predictions sellers however price much lower and advertise more intensely than predicted consequently market outcomes more closely resemble a perfect information bertrand like equilibrium than the imperfect information mixed strategy equilibrium with significant seller market power

the great moderation in international capital flows a global phenomenon abstract this paper highlights a recent great moderation in global capital flows characterised by smaller volumes and lower volatility of cross border transactions however there are substantial differences across countries and regions which we analyse by comparing the level of international capital flows observed in 2005 06 immediately prior to the onset of the global financial crisis to the post crisis period of 2013 14 when global flows arguably settled at a new normal we find that since the pre crisis period gross capital inflows recovered more for economies with smaller pre crisis external and internal imbalances lower per capita income improving growth expectations a less severe impact of the global financial crisis and less stringent macroprudential policy on the asset side countries with a more accommodative monetary policy a milder impact of the crisis and oil exporters managed to increase gross capital outflows in the post crisis period

toward an economic model of the japanese firm i owe a great deal to professor moses abramovitz who suggested that i write this article i appreciate his constant encouragement and guidance which aided me throughout its preparation i am also indebted to three anonymous referees of the journal and to professors ryutaro komiya and michael riordan for their critical comments and helpful suggestions needless to say i am solely responsible for the views expressed in this paper

the home bias is here to stay over the last 15 years dramatically decreasing foreign investment costs have not reduced the home bias we show that the home bias induced by a given cost is proportional to the factor 1 where is the average correlation between markets this factor is very sensitive to the correlation especially when the correlation is high empirically correlations have been steadily increasing from 0 4 in the 90 s to about 0 9 today thus the decreasing extra costs are increasingly magnified explaining the persistence of the home bias and predicting its continuation

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

daily cross border equity flows pushed or pulled we investigate the conditions under which an intertemporal equilibrium model based on investors portfolio decisions can explain the dynamics of high frequency equity flows our model shows that w

job search stigma effect and escape rate from unemployment this article formulates job search models incorporating certain types of the stigma effect of unemployment it is assumed that the probability of getting a job offer given the unemployment individual contacts the firm is influenced by the duration of unemployment and is justified in a signaling context the optimal search is analyzed for one sector as well as across several independent labor market segments it is shown that there are reasonably general conditions on the search environments for which both the individual reservation wage and escape rate are negative duration dependent a fact observed in empirical studies

toward a theory of vacancies we attempt to further characterize the search strategies of the employer in the article we discuss how characteristics of the employer or conditions that the employer faces affect the optimal search strategies and the probability of filling a vacancy in each period semiparametric and parametric methods are used to estimate hazard rates of filling vacancies the results suggest that for the given sample of vacancies the general form of the hazard function is nonmonotonic additionally the results suggest that those employers who have advance notice of the vacancy may search longer than those employers who do not

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

home bias and high turnover dynamic portfolio choice with incomplete markets why do investors trade a lot in foreign assets and hold so little of them in their portfolios this paper shows that both observations can arise naturally in the presence of nondiversifiable nontraded consumption risk when each country specializes in production preferences exhibit consumption home bias and asset markets are incomplete using a general equilibrium two country two sector tradable and nontradable model of the world economy with production i show that low diversification occurs because variations in relative prices i increase the riskiness of foreign assets and ii facilitate risk sharing across countries large and volatile capital flows are necessary to take advantage of international risk premia differentials that occur in response to productivity changes in the nontradable sector i characterize the optimal portfolio holdings the evolution of the investment opportunity set the risk premium and the dynamics of capital flows using a new methodology for solving dynamic general equilibrium models with incomplete markets and portfolio choice

global capital flows and financing constraints firms often cite financing constraints as one of their primary obstacles to investment global capital flows by bringing in scarce capital may ease the financing constraints of host country firms but if incoming foreign investors borrow heavily from domestic banks foreign direct investment may exacerbate financing constraints by crowding host country firms out of domestic capital markets combining a unique cross country firm level panel with time series data on restrictions on international transactions and capital flows harrison love and mcmillan find that different measures of global flows are associated with a reduction in firm level financing constraints first the authors show that one type of capital inflow foreign direct investment is associated with a reduction in financing constraints second they test whether restrictions on international transactions affects the financing constraints of firms the results suggest that only one type of restriction those on capital account transactions negatively affects firms financing constraints the authors also show that multinational firms are not financially constrained and do not appear to be sensitive to the level of foreign direct investment this implies that foreign direct investment eases financing constraints for non multinational firms finally the authors show that 1 foreign direct investment only eases financing constraints in the non g7 countries and 2 other kinds of flows such as portfolio investment have no impact on financing constraints

a century of global equity market correlations in this paper we use a unique long run dataset of regulatory constraints on capital account openness to explain stock market correlations since stock returns themselves are highly volatile any examination of what drives correlations needs to focus on long runs of data this is particularly true since some of the short term changes in co movements appear to reverse themselves delroy hunter 2005 we argue that changes in the co movement of indices have not been random rather they are mainly driven by greater freedom to move funds from one country to another in related work geert bekaert and campbell harvey 2000 show that equity correlations increase after liberalization of capital markets using a number of case studies from emerging countries we examine this pattern systematically for the last century and find it to be most pronounced in the recent past we compare the importance of capital account openness with one main alternative explanation the growing synchronization of economic fundamentals we conclude that greater openness has been the single most important cause of growing correlations during the last quarter of a century though increasingly correlated economic fundamentals also matter in the conclusion we offer some thoughts on why the effects of greater openness appear to be so much stronger today than they were during the last era of globalization before 1914 this abstract was borrowed from another version of this item

portfolio preferences of foreign institutional investors the authors examine the relationship between foreign investment and the attributes of emerging market countries and firms in which investment is made their findings indicate that countries with higher levels of economic development and floating exchange rate regimes tend to have greater ability to obtain foreign capital after controlling for the country s level of economic development they find that firms in countries with stronger shareholder rights and legal framework attract more foreign capital the authors also find that foreign institutions allocate more of their assets to firms with better corporate governance after controlling for other country and firm attributes the main firm level measures of corporate governance are derived from accounting quality variables their results imply that steps can be taken both at the country and the firm level to create an environment conducive to foreign portfolio investment the analysis is based on a unique dataset consisting of equity positions of u s mutual funds in emerging markets

explanations of unemployment economists commonly distinguish between two sorts of unemployment roughly speak ing the involuntarily unemployed workers are unwillingly out of work i e they feel that they would be better off with jobs on the other hand the voluntarily unemployed workers prefer to be out of work for any of a wide variety of reasons e g because they are searching or training for a job or because they choose leisure over work

legal harmonization institutional quality and countries external positions a sectoral analysis abstract motivated by the action plan for a european capital markets union cmu this paper analyzes the potential for legal harmonization and convergence in institutional quality to affect capital market integration based on hand collected data on the implementation of eu directives our analysis yields three key insights first legal harmonization promotes portfolio equity holdings second discrepancies in institutional quality matter primarily for cross border debt positions third the relationship between external investments and harmonization varies significantly across sectors the non bank financial corporations which account for a large share of portfolio positions react more to institutional harmonization than do banks and the non financial private sector

big fish in small ponds the trading behavior and price impact of foreign investors in asian emerging equity markets this paper analyzes a new dataset for the aggregate daily trading of all foreign investors in six asian emerging equity markets and provides two new findings first foreigners flows into several markets show positive feedback trading with respect to global as well as domestic equity returns the nature of this trading suggests it is due to behavioral factors or foreigners extracting information from recent returns rather than portfolio rebalancing effects second the price impacts associated with foreigners trading are much larger than earlier estimates the results suggest that foreign investors and external conditions have a larger impact on emerging markets than implied by previous work

equity home bias and corporate disclosure abstract i show that more comprehensive corporate disclosure reduces investors uncertainty about domestic companies payoffs at no cost thereby decreasing investors equity home bias toward a country since investors should base their investment decisions on valid and easily interpretable company information only more comprehensive disclosure will reduce the home bias only if domestic securities law is sufficiently stratified and domestic companies use international accounting standards using panel data for 38 countries from 2003 to 2008 i find that more comprehensive disclosure reduces investors home bias though significantly only for countries that sufficiently enforce their securities law and implement international accounting standards

declining reservation wages and learning empirical studies of job search strongly suggest that the reservation wages of unemployed job seeking individuals decline with the length of their respective unemployment spells previous explanations of this behaviour based on age effects liquidity constraints and limited unemployment benefits are not adequate we provide a new answer to this question based on the reasonable assumption that workers do not have precise knowledge of the distribution of the prevailing wages an individual model of job search and learning is formulated it is shown that the declining trend of reservation wages naturally arises due to the selection process when search costs are not too small the example of a normal wage offer distribution is analysed and the implications are discussed

systematic and random search a synthesis this paper synthesizes two models of search in the labor market systematic and random we construct and test a theoretical model in which the searcher is endowed with information on some possibly zero or all individual firms in the labor market as well as the overall wage offer distribution we test the model using a special wave of the 1976 current population survey the major theoretical results of our model are as follows searchers with lower stocks of knowledge about individual firms higher discount rates or having lower coverage by unemployment insurance are more likely to engage in random search activities

the critical wage unemployment duration and wage expectations the case of chile this study tests the relevance of the job search model to understanding unemployment in developing countries by utilizing a 1982 data set describing unemployed men in chile the findings indicate t

on availability discrimination under rent control statistical discrimination and search theory approaches are used to consider the behavior of a landlord with a vacant rental unit often and especially under rent control rents cannot be differentiated by tenant type although the expected maintenance and removal costs of observationally separable tenant groups may differ assuming that prospective tenants appear according to a random process when sought we solve the landlord s decision problems i whether he should search for a tenant or keep the rental unit unoccupied and ii if search is undertaken how long he should wait for a good tenant

education and the duration of job search and unemployment in urban india an empirical analysis based on a survey of delhi jobseekers abstract this paper investigates why educated jobseekers tend to experience longer search and unemployment durations than their less educated counterparts the empirical analysis based upon a survey of delhi jobseekers indicates that while the duration of search is mainly determined by educational level the duration of unemployment is more closely related to personal and family characteristics normally associated with education earnings function results are consistent with the proposition that the educated search longer because their returns are higher

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

on the job search in a developing country an analysis based on indian data on migrants job search by those who are employed has received increasing attention in recent years in both the theoretical and the empirical literature on labor markets in developed countries much of the interest stems from the observation that job changes often take place without an intervening period of unemployment and that there is a close relationship between searching for a job and quitting the current job also on the job search affects the rate of unemployment during the period between jobs a major preoccupation of the empirical research has been to estimate the returns to on the job search and to test the determinants of job search the bulk of this work uses data for the united states and the united kingdom 2 job search theory has not been empirically tested in the context of a developing country on the job search particularly in the so called informal sector of the urban labor market is an important feature of probabilistic models of migration in developing countries in the vein of michael p todaro and of john r harris and todaro 3 such models hypothesize that individuals migrate to urban centers with the aim of obtaining employment in the formal sector and that informal sector employment is a transitional phase during which migrants are searching for formal sector jobs recent work by gary s fields has formalized the theoretical aspects of this job search process within the framework of a multisector model 4 thus it would be of interest to find out if there are significant differences between developed and developing countries with respect to the determinants of on the job search

on modelling the informal sector abstract a recent plea by robert hackenberg to develop new conceptual models in order to take full account of the new realities of the urban informal sector and rid the field from divergent connotations is questioned it seems that existing models easily lend themselves to analysis of the formal informal sector interactions and that divergent conditions necessarily lead to contradictions thus the existing arsenal of models cannot be held responsible for analysis paralysis new research on the informal sector rather than aiming at ultra generalizations should concentrate on issues such as identification of the determining factors of the urban production technologies and the nature of linkages and elasticity of substitution between formal and informal production

new evidence on whether unemployment and out of the labor force are distinct states this paper focuses on the question of whether people who are out of the labor force olf should be included in unemployment measures if people who are olf can obtain jobs as often as the people who are unemployed then there is no real distinction between the two states of nonemployment surprisingly there has been very little effort surrounding this issue in the past clark and summers 1982 conclude that for teenagers unemployment and olf are not distinct states while flinn and heckman 1982a find the opposite for white male high school graduates the methodology adopted in this paper enables one to use incomplete transition data on unemployment and olf and to obtain estimates of the full transition matrix between three labor force states that are not possible with standard methods new evidence for high school graduates is presented by gender and it is found that while for young women the two states are distinct for young men they are not

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

environmental scanning in korean firms organizational isomorphism in action this paper reports some of the findings of a study on environmental scanning practices in six large korean firms and compares the results with those of previous studies on scanning conducted in the united states such comparisons are made for both the scanning behaviors of individual managers and the structures roles and systems of formal environmental scanning units the overall conclusion that emerges is that while scanning behaviors of american and korean firms are quite similar on average they differ significantly in the extents of inter organizational variances in the two societies scanning practices of u s firms are diverse while those of korean firms are remarkably similar

imperfect information and labor market bias against small and medium sized enterprises a korean case we examine the labor market s bias against small and medium sized enterprises focusing on the seoul digital industrial complex case we adopt heckman s approach to control selection bias and use primary data from questionnaire surveys conducted at both firm and employee levels we find that conventional firm specific factors such as wages fringe benefits and weekly work hours primarily explain the labor market bias but imperfect information is also positively associated with the bias for example a firm s inadequate ability to identify a pool of potential employee candidates or to provide them comprehensive firm or job specific information tends to worsen labor shortages and an employee s ex ante incomplete knowledge of on the job training or education opportunities tends to increase ex post turnover intentions our results suggest that reducing the market bias requires improving imperfect information as well as conventional firm specific conditions

capital control liberalization and stock market development the authors address two questions what happens to stock market size liquidity volatility and integration with world capital markets after capital controls are liberalized and what is the relationship between those indicators of stock market development and regulations about information disclosure accounting standards and investor protection an analysis of data on stock markets in 16 developing countries suggests the following a stock markets become larger more liquid more integrated internationally and more volatile after controls on capital and dividend flows are liberalized b easy access to information about firms is positively associated with the size and liquidity of stock markets and c countries that officially establish internationally accepted accounting standards and laws to protect investors do not have substantially better functioning stock markets than countries that do not adopt those official standards

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

real time search in the laboratory and the market the standard model of labor market search posits repeated infinite horizon search from a fixed distribution of wages in a stationary environment under these circumstances the optimal search policy has a reservation wage property i e the decision to accept an offer involves a comparison of the offer with a time invariant constant w which itself is a function of the parameters characterizing the search environment a wage offer greater than or equal to w is accepted while any other is rejected and search is continued some early empirical job search studies however accumulated evidence of a declining trend in reservation wages over the course of an unemployment spell 1 since then several theoretical explanations for the declining reservation wage profiles have emerged all of which relax the stationarity assumption of the standard model for example reuben gronau 1971 assumes searchers have finite lives kenneth burdett 1977 gerard j van den berg 1990 james albrecht and susan vroman 2005 and others model short term unemployment benefits albrecht pieter a gautier and vroman 2006 permit directed search to heterogeneous prospects 2 john p danforth 1979 and silvio rendon 2006 consider general liquidity con strained search and burdett and tara vishwanath 1988 model learning about the job offer distribution behavioral explanations for declining reservation wages have been suggested by braunstein and schotter 1981 schotter and braunstein 1982 and others in this paper we present the results of the first ever to our knowledge real time search laboratory experiment performed in an effort to investigate this falling res ervation wage phenomenon where field studies of unemployed search often rely on strong identifying assumptions to recover searchers unobservable reservation wages in the laboratory we are able to elicit subjects complete reservation wage profiles in an incentive compatible manner 3 further in the laboratory we are able to

optimal sequential investment decisions under conditions of uncertainty this paper presents a mathematical model of sequential investment behavior under conditions of uncertainty the model addresses the problem of an investor with access to a limited pool of capital who makes sequential decisions on long lasting investments under uncertainty as to the timing or the quality of future opportunities we derive optimal investment strategies for the cases where the return from investment is a convex or concave function we present closed form solutions for commonly adopted return functions and we evaluate how the optimal investment behavior should change when changes occur in the environment or the underlying probability distributions in addition we analyze three modifications of the problem the results presented in this paper extend previous results on investment behavior for long lasting irreversible decisions in addition some results are in accordance with existing ones from portfolio theory and or search theory

young workers and quit behaviour a model is set up to explain the quit behaviour of new entrants to the labour market it uses an incentive opportunity approach to integrate existing relevant arguments from search and information theory and human capital analysis it also provides for impetuous quits the model is tested by an examination of a disaggregated data set concerning a single cohort of 16 year old school leavers in the first year after gaining full time work the theory received strong support for example in the main model seven out of the ten coefficients were highly significant interestingly even in a time of deepening recession the existence of the job shopper seemed to be apparent

direct foreign ownership institutional investors and firm characteristics in this paper we characterize foreign ownership using a dataset of ownership and attributes of swedish rms the analysis reveals that foreigners show a preference for large rms rms paying low dividends and rms with large cash positions on their balance sheets when we further analyze the preference for large rms we nd that market liquidity and presence in international markets measured through export sales or listings on other exchanges seem to characterize foreign holdings better than rm size alone foreigners also tend to underweight rms with a dominant owner importantly we demonstrate that most of the features associated with foreign ownership are driven by the fact that foreign investors typically are mutual funds or other institutional investors hence we identify an institutional investor bias rather than a foreign investor bias finally using ownership data on a country level we conclude that the results are particularly strong among u s investors who comprise the largest institutions among foreign investors 2001 elsevier science s a all rights reserved jel classixcation g1 g15

information aggregation in a noisy rational expectations economy abstract this paper analyzes a general equilibrium model of a competitive security market in which traders possess independent pieces of information about the return of a risky asset each trader conditions his estimate of the return both on his own private source of information and price which in equilibrium serves as a noisy aggregator of the total information observed by all traders a closed form characterization of the rational expectations equilibrium is presented a counter example to the existence of fully revealing equilibrium is developed
