dynamic linkages among equity markets local versus basket currencies this article compares the stability of interrelationships among nine national equity markets by employing basket currencies versus individual base currencies to measure rates of return we show that the average correlations of equity indexes based on basket currencies are much lower than the average correlations of equity indexes based on individual home base currencies additionally empirical directed graph results from using basket currencies are more consistent with each other than the results from using different individual currencies we conclude that basket currencies provide more robust results for studying equity market comovements than individual currencies by implication studies on equity market interrelationships including studies on potential financial contagion between equity markets should use basket currencies to avoid currency dependent results

after hours stock prices and post crash hangovers after hours pricing in foreign equity markets of multiple listed u s securities appeared to be efficient in predicting new york prices in the weeks immediately following the october 1987 crash but relatively uninformative in succeeding months by contrast daily changes in new york prices appear to be efficiently incorporated in after hours trading on both the tokyo and london exchanges throughout the sample period this paper suggests that the asymmetry and temporal variations in cross market correlations are consistent with rational investor behavior in equity markets with nonzero transaction costs and time varying share price volatility in the wake of the october 1987 crash a number of studies have provided evidence of significant international linkages among national equity markets where high frequency movements in the share price indices of national exchanges appear to induce sympathetic price movements in subsequent trading on other national exchanges however the cross market correlations are generally much larger in periods of extreme volatility and appear to subside to modest or even negligible associations during periods of more normal trading activity since the constituent stocks of national exchange indices are not identical it may be that the episodic increases in correlated movements of the indices are due to changes in the actual or perceived relative importance of common factors in periods of unusual volatility the thrust of this paper is to remove the issue of the disparate composition of the price indices of national exchanges by examining the prices of a set of

contagion around the october 1987 stock market crash abstract this study investigates financial contagion among seven international stock markets around the october 19 1987 crash building on a recent advance in vector autoregression analysis by swanson n granger c w j 1997 impulse response functions based on a causal approach to residual orthogonalization in vector autoregression journal of the american statistical association 92 357 367 data determined historical decompositions are conducted to provide a day by day picture of price fluctuation transmission which is crucial to explore the financial contagion pattern characterized by rich dynamics the results clearly show that the crash originated in the us market and that an upward movement in the japanese market after the crash helped the recovery in the us market which has not yet been empirically documented in the literature

an investigation into the interdependence of global water indices a var analysis we investigate the extent and manner of equity price interdependence among four water indices world water index s network global water index s net s p global water index s p and msci acwi water utilities index msci acwi using the vector autoregression var framework for the period 2004 2014 we also employ methods of granger causalities variance decomposition and impulse responses we find granger causality significance between s net and msci acwi and s net and s p indices at the 1 level of significance suggesting that the indices are significantly linked further s net is the most influential index amongst them in the forecast variance that can be accounted by s net at level of 55 75 our study indicates that the four water indices are interdependent and related so the water indices are influenced by movements in the other water indices

on the risk spillover across the oil market stock market and the oil related cds sectors a volatility impulse response approach abstract compared to credit default swap cds literature this study focuses on the magnitude of volatility transmission and the risk spillover mechanism across the oil market financial market risks and the oil related cds sectors our dataset includes futures prices of west texas intermediate wti and seven different measures of markets and credit risks four of the vast risk measures are the oil related cdss for auto chemicals natural gas and utility sectors in addition three measures of the financial market risk the one month expected equity volatility measured by vix move and smove are included the daily dataset covers the period from 6 january 2004 to 2 february 2016 the volatility transmission mechanism across the oil and financial markets and cds sectors is examined using the volatility impulse response model we evaluate the risk transmission due to several recent crisis shocks around the world and the results show complicated transmission mechanisms that spread over long periods among these events the lehman brothers bankruptcy has destabilizing effects on all oil related sectors findings also show that all oil market related shocks have significant risk transmission effects

changes in the comovement of european equity markets this paper investigates the impact that the removal of exchange controls within major european economies has had on the interdependence of european equity markets for five years prior to the removal of exchange controls and five years following their removal we use impulse responses and variance decompositions from vector autoregressions to illustrate that european equity markets have become substantially more integrated after the removal of exchange controls we undertake further tests that demonstrate that even if we allow for parallel macroeconomic harmonization the removal of exchange controls has been a major cause of increased equity market integration within europe

the intertemporal relation between the u s and japanese stock markets this paper finds a high correlation between the open to close returns for u s stocks in the previous trading day and the japanese equity market performance in the current period in contrast the japanese market has only a small impact on the u s return in the current period high correlations among open to close returns are a violation of the efflcient market hypothesis however in trading simulations the excess profits in japan vanish when transactions costs and transfer taxes are included the two largest stock markets in the world in terms of capitalization volume and shares listed are the tokyo stock exchange tse and the new york stock exchange nyse because tokyo is 14 hours ahead of new york there is an eight and one half hour difference between the close of the tse and open of the nyse since there is no overlap between the two markets traders or technical analysts may look to the tse as a predictor of market movement on the nyse and or examine changes on the nyse as indicators of tse performance as shown in figure 1 the tse opens at 7 00 p m eastern standard time est and closes at 1 00 a m est 1 the nyse opens at 11 30 p m japanese time 9 30 a m est and closes at 5 00 a m japanese time 4 00 p m est thus there is no common time interval in which both markets are open high correlations between the respective open to close returns are a violation of the efficient market hypothesis because public information about the performance in one market could be used to profitably trade in another market if the markets are efficient information about the open to close performance in one market for example the u s return in period t 1 will be fully reflected in the open price of the other market japan in period t for example since new information flows randomly into the market subsequent price changes should be random and the open to close returns in japan will be uncorrelated with the u s returns thus the u s performance should affect the open price in japan and the correlation between the open to close returns of the two markets will be zero early research on the synchronization among stock prices across countries grubel 1968 levy and sarnat 1970 agmon 1972 ripley 1973 lessard

leads lags and trading in global markets the development of capital markets around the world has given rise to growing interest in how the markets are linked this study using the dow jones company country and industry indexes found that the united states has statistically significant one day leads over markets in europe and asia that no significant leads extend beyond one day that changes in foreign exchange rates contribute to the links among markets and that the industries designated global are significantly more sensitive to leads than are local industries lead lag relationships may allow yield enhancement possibly even arbitrage through trading futures in some markets

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

international stock market linkages evidence from the pre and post october 1987 period abstract this paper uses recent developments in the theory of cointegration to provide new methods of testing the linkage and dynamic interactions among stock market movements our findings are in sharp contrast with previous research which discovered strong interdependence among national stock markets prior to october 1987 for the post october 1987 period however our results show that the degree of international co movements among stock price indices has increased substantially with the nikkei index the only exception furthermore the us stock market is found to have a considerable impact on the french german and uk markets in the post crash period we also find the response of the french german and uk markets to us stock market innovations to be consistent with the view of cross border informationally efficient stock markets finally we find the japanese equity market performance to have no links with both the us stock market and the stock markets in france germany and uk during the pre and post october crash period

international stock market efficiency a non bayesian time varying model approach this article develops a non bayesian methodology to analyse the time varying structure of international linkages and market efficiency in g7 countries we consider a non bayesian time varying vector autoregressive tv var model and apply it to estimate the joint degree of market efficiency in the sense of fama 1970 1991 our empirical results provide a new perspective that the international linkages and market efficiency change over time and that their behaviours correspond well to historical events of the international financial system

interaction between stock markets an analysis of the common trading hours at the london and new york stock exchange abstract this paper examines the spill overs in both returns and volatility between the london and new york stock markets during overlapping trading hours using high frequency data for the ftse and s p stock index futures we estimate the seasonal patterns in volatility using a flexible fourier form specification the estimated seasonals are used to adjust the returns before conducting the lead lag analysis the results indicate that both markets influence each other although the impact of the usa on the uk is clearly stronger

a new approach to measuring financial contagion this article proposes a new approach to evaluate contagion in financial markets our measure of contagion captures the coincidence of extreme return shocks across countries within a region and across regions we characterize the extent of contagion its economic significance and its determinants using a multinomial logistic regression model applying our approach to daily returns of emerging markets during the 1990s we find that contagion is predictable and depends on regional interest rates exchange rate changes and conditional stock return volatility evidence that contagion is stronger for extreme negative returns than for extreme positive returns is mixed

returns synchronization and daily correlation dynamics between international stock markets the use of close to close returns underestimates returns correlation because international stock markets have different trading hours with the availability of 16 00 london time stock market series we find dynamics of daily correlation and covariance estimated using two non synchroneity adjustment procedures to be substantially different from their synchronous counterparts conditional correlation may have different signs depending on the model and data type used other findings include volatility spillover from the us to the uk and france and a reverse spillover which is not documented before also unlike previous findings we found the increase in daily correlation is prominent only under extremely adverse conditions when a large negative return has been registered

unravelling financial market linkages during crises an empirical model of multiple asset classes across countries is formulated in a latent factor framework a special feature of the model is that financial market linkages during periods of financial crises including spillover and contagion effects are formally specified the model also captures a range of common factors including global shocks country and market shocks and idiosyncratic shocks the framework is applied to modelling linkages between currency and equity markets during the east asian financial crisis of 1997 98 the results provide strong evidence that cross market links are important spillovers have a relatively larger effect on volatility than contagion but both are statistically significant

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

information transmission and market interactions across the atlantic an empirical study on the natural gas market abstract this paper studies the international information transmission and market interactions in the u s and u k natural gas markets three well documented approaches are used to measure the relative importance on the process of price discovery under a quadvariate system after adjusting the effects of nonsynchronous trading prices robust results indicate our system that includes spot and futures prices within the two countries are driven by one common factor information disseminates efficiently among the four markets concerned the u s futures market dominates as the center for price discovery the u k futures market comes as the second the spot markets in the u s and u k are less efficient than their corresponding futures market where the u k spot market contributes the least and almost zero to the price discovery process asymmetric volatility spillovers are found in three of the four markets volatility in the u s futures market increases with positive returns which illustrates the inverse leverage effect in most of the commodity market volatilities in the spot markets are negatively related to returns which is analogous to the traditional leverage effect prevailing in most of the equity stock markets

disability transfers and the work decision of older men the potential causal relationship between the availability and generosity of disability transfers and the nonparticipation rates of older men is often asserted and much studied parsons 1980 haveman and wolfe 1984 leonard 1986 however estimates of the magnitude of this linkage vary widely the growth in transfer availability and generosity has been credited with from 30 to 100 percent of the significant post 1960 fall in older male participation rates the disparity in these research results stems primarily from 1 alternative sources of data that differentially constrain estimation of relevant expected wage and transfer incomes 2 specifications that are unable to distinguish income transfer from labor market effects and 3 reliance on measures of health status that are endogenous to the work leisure decision this study seeks to narrow the range of estimates by addressing each of these issues our utility maximization model of work status choice assumes that workers who differ in health status choose between the mutually exclusive options of working at the wage offered for their characteristics and accepting public or private disability transfers because the income flows in the two options are censored they are estimated using switching regression techniques as expectations conditional on exogenous individual characteristics hence accounting for the potentially endogenous process that separates wage earners from transfer recipients the marginal utilities of income from the two sources are allowed to differ because of stigma effects in the estimation we adjust the choice based nature of our sample employ longitudinal earnings data to measure expected changes in as distinct from the expected level of income in the two options and use a separately estimated latent health status measure largely purged of its endogeneity with the participation decision

the emerging market crisis and stock market linkages further evidence this study examines the long run price relationship and the dynamic price transmission among the usa germany and four major eastern european emerging stock markets with particular attention to the impact of the 1998 russian financial crisis the results show that both the long run price relationship and the dynamic price transmission were strengthened among these markets after the crisis the influence of germany became noticeable on all the eastern european markets only after the crisis but not before the crisis we also conduct a rolling generalized var analysis to confirm the robustness of the main findings copyright 2006 john wiley sons ltd

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

holiday effects and stock returns further evidence this paper provides further evidence of the holiday effect in stock returns and additional insight into the effect this paper reports abnormally high returns on the trading day before holidays in all three of the major stock markets in the u s the nyse amex and nasdaq the holiday effect is also present in the u k and japanese stock markets even though each country has different holidays and institutional arrangements this study finds that the holiday effects in the u k and japanese stock markets are independent of the holiday effect in the u s stock market unlike the other seasonal patterns in stock returns such as january and weekend effects this investigation of size decile portfolios shows that the size effect is not present in mean returns on preholidays

a multivariate garch model of international transmissions of stock returns and volatility the case of the united states and canada this study examines the short run dynamics of returns and volatility for stocks traded on the new york and toronto stock exchanges the main finding is that inferences about the magnitude and persistence of return innovations that originate in either market and that transmit to the other market depend importantly on how the cross market dynamics in volatility are modeled moreover much weaker cross market dynamics in returns and volatility prevail during later subperiods and especially for canadian stocks with shares dually listed in new york implications for international asset pricing hedging strategies and regulatory policy are discussed

the international transmission of information in eurodollar futures markets a continuously trading market hypothesis abstract this paper studies the transmission of information in three eurodollar futures markets the imm simex and liffe the results show that relevant information is revealed during the trading hours of the imm and liffe but not the simex the interest rates of the three markets are cointegrated with a single common stochastic trend granger causality runs from the market that is placed in the last trading order within 24 hours in the vector error correction model and this causal relationship is shorter than one day an approach of variance decomposition and impulse response functions exploring the common factor in the cointegration system is employed analogous to the causality results the common factor is driven by the last trading market in the 24 hour trading sequence specifically each market while it is trading impounds all the information and rides on the common stochastic trend the overall results suggest that these three markets can be considered one continuously trading market

the relation between aggregate insider transactions and stock market returns a vector autoregressive var model is used to examine the relation between aggregate insider transactions and stock market returns consistent with the extant literature there is some predictive content associated with aggregate insider transactions but its magnitude is slight in contrast market returns have substantial influence on the aggregate purchases and sales of corporate insiders the findings suggest that 1 the degree of mispricing observed by insiders is small 2 very little of the mispricing is associated with unanticipated macroeconomic factors and 3 investors cannot use aggregate insider transactions to profitably predict future market returns over the following eight weeks

determinants of flows into retail international equity funds diversification benefits appear to be a major reason why investors choose international equity funds funds less correlated with the us market tend to receive higher flows from investors in addition investors prefer funds that invest in a diversified portfolio of securities from different regions in the world to funds that focus only on a specific region risk adjusted return is shown to exert greater effect on flows into international equity funds than raw return international equity funds from fund families offering a greater number of investment objectives also receive higher flows on the other hand international equity fund investors do not appear to be sensitive to expenses or exchange rates

international transmission of stock market movements this paper investigates the international transmission mechanism of stock market movements by estimating a nine market vector autoregression var system using simulated responses of the estimated var system we i locate all the main channels of interactions among national stock markets and ii trace out the dynamic responses of one market to innovations in another generally speaking a substantial amount of multi lateral interaction is detected among national stock markets innovations in the u s are rapidly transmitted to other markets in a clearly recognizable fashion whereas no single foreign market can significantly explain the u s market movements also the dynamic response pattern is found to be generally consistent with the notion of informationally efficient international stock markets

post injury work outcomes revisited we use data for ontario workers with permanent impairments resulting from work related injuries to investigate the complex relationships among post injury work outcomes wages accommodations returning to the same or different employer and duration of work absence we argue the different aspects of post injury work experience may be jointly determined making post injury job characteristics endogenous in a duration model to explore the endogeneity issues we instrument post injury job variables from first stage equations and compare results from this informed model to a naive model that treats the variables as exogenous we find that returning to one s pre injury employer is associated with more favorable post injury work outcomes including higher wages greater likelihood of job accommodations and shorter durations of work absence relative to workers who change employers we also find substantial differences between the naive and informed models with accommodations having the predicted negative effect on duration only after we control for endogeneity

stock returns and the transfer of information between the new york and tokyo stock exchanges abstract this study examines the transmission of pricing information between the new york nyse and tokyo tse stock exchanges using opening and closing stock prices for seven japanese firms the results of this study suggest that 1 sample firm tse opening returns respond to changes in sample firm nyse intraday stock performance with transmission apparently completed at the tse opening and 2 sample firm nyse opening returns as well as subsequent trading respond to changes in sample firm tse intraday stock performance taken together the evidence reported in this study is generally consistent with the notion of semi strong form market efficiency jel g15

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

incentive effects of workers compensation insurance abstract this paper uses micro level data from the current population survey to estimate the determinants of participation in state workers compensation programs in the united states the principal finding is that higher workers compensation benefits are associated with greater participation in the workers compensation program after accounting for a variety of covariates in addition the waiting period is found to have a substantial negative effect on program participation finally time series estimates based on the cross sectional model show that the growth in workers compensation claims in the 1970s corresponds reasonably well with the growth in real benefits in this time period

asymmetric volatility transmission in international stock markets abstract the transmission mechanism of price and volatility spillovers across the new york tokyo and london stock markets is investigated the asymmetric impact of good news market advances and bad news market declines on volatility transmission is described by an extended multivariate exponential generalized autoregressive conditionally heteroskedastic egarch model using daily open to close returns we find strong evidence that volatility spillovers in a given market are much more pronounced when the news arriving from the last market to trade is bad a before and after october 1987 crash analysis reveals that the linkages and interactions among the three markets have increased substantially in the post crash era suggesting that national markets have grown more interdependent

the relationship between daily u s and japanese equity prices evidence from spot versus futures markets abstract the daily and overnight transmission of equity prices between the u s and japan is examined in this paper this study documents that the use of the opening value of an equity index to represent equity prices at the open is unlikely to be reliable and the calculated opening values of the nikkei 225 and especially the s p500 indexes mostly reflect prior days closing prices unlike prior studies this paper accounts for this problem of non synchronous trading at the open and finds that u s equity prices do not lead japanese equity prices as both u s and japanese opening equity prices reflect overnight price changes in the other market

stale prices and strategies for trading mutual funds we demonstrate that an institutional feature of numerous mutual funds funds managing billions in assets generates fund net asset values that reflect stale prices because investors can trade at these navs with limited transaction costs in many cases obvious trading opportunities exist these opportunities are especially prevalent in funds that buy japanese or european equities simple feasible strategies generate sharpe ratios excess return divided by standard deviation that are many times greater than the sharpe ratio of the underlying fund we illustrate the potential of the strategy for three vanguard group mutual funds a particular issue to keep in mind is that when the strategies are implemented the gains from these strategies are matched by offsetting losses incurred by buy and hold investors in these funds

superexogeneity and the dynamic linkages among international equity markets abstract in this article we combine the johansen procedure for cointegration testing with tests of weak exogeneity and invariance in order to ascertain whether a system of equity markets is characterized by superexogeneity superexogeneity is rejected for the system comprised of stock indices of the us uk germany and japan this finding implies that agents participating in these financial markets are forward looking all markets are endogenous in our system and the assumption of stability of the asset demand function is questionable

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

economic news and equity market linkages between the u s and u k abstract the source of equity market linkages between the u s and u k is investigated by focusing on intraday price movements of stock index futures contracts we document heightened u k return volatility at 11 30 a m and 1 30 p m gmt which corresponds to regular macroeconomic releases in the u k and u s respectively the response of u k equities in the half hour surrounding the u s announcements is significant and similar to price movements for u s equities to the same announcements these results support the hypothesis that the documented international equity market linkages are attributable to reactions of foreign traders to public information originating from the u s

correlated arch corrarch modelling the time varying conditional correlation between financial asset returns abstract although the time variation of the conditional correlations of asset returns is a well established stylized fact and of crucial importance for efficient financial decisions there is no explicit general model available for its estimation and forecasting in this paper we propose a bivariate garch covariance structure in which conditional variances can follow any garch type process while conditional correlation is generated by an explicit discrete time stochastic process the corrarch process a high order corrarch can parsimoniously be represented by a corgarch process the model successfully generates the reported stylized facts establishes an autocorrelation structure for correlations and thus provides an explicit framework for out of sample forecasting we provide empirical evidence from the g7 stock market indexes

spillover effects in energy futures markets price discovery in crude oil and refined oil products has been extensively undertaken in organised futures markets for over a decade now there are two dominant such markets today the first one in the new york mercantile exchange and the second in london s international petroleum exchange with the demise of opec as the leading price setter for crude and products nymex light sweet crude and brent crude have usurped the role of benchmark grades for price setting to date considerable work has been done to scrutinise the degree to which these two markets price efficiently but little with regard to the way the two markets interact participants in these markets move with relative ease from one market to the other and usually take positions in both of them it is of interest therefore to investigate the information transmission mechanism by looking at spillover effects and perhaps identify which market is the true price leader this paper is a first attempt to look at such a problem in the energy market although similar studies have been done on stock market indices it is found that substantial spillover effects do exist when both markets are trading simultaneously although ipe morning prices seem to be considerably affected by the close of the previous day on nymex q 2001 elsevier science b v all rights reserved

interdependencies among the nordic and u s stock markets using the concept of granger causality interdependencies among the stock market indices for four nordic countries and the u s are examined the vector autoregressive model results indicate that the u s market affected only the danish but not the norwegian finnish or swedish markets the swedish market was causally prior to both the norwegian and finnish markets the norwegian danish and finnish markets did not granger cause any other market the results indicate that the nordic stock markets are less than fully integrated

why no backsliding the european union s impact on democracy and governance before and after accession this article documents and explains the puzzling lack of backsliding in political reforms among the new postcommunist eu members even though these countries are no longer subject to the powerful incentives of the eu membership promise using a combination of cross national statistics expert interviews and public opinion data the authors show that the new eu members have experienced at most a slowdown in reforms rather than a genuine backlash the authors attribute this finding to the fact that the loss of leverage after the countries joined the european union was balanced by a combination of alternative leverage and linkage mechanisms including greater dependence on eu aid and trade and greater exposure to the west for both elites and ordinary citizens for the latter expanded work and travel opportunities seem to be associated with higher expectations of government performance and greater political involvement which may be crucial for future governance reform in the region

the dynamic relationship between stock returns and trading volume domestic and cross country evidence abstract this paper examines the dynamic relations causal relations and the sign and magnitude of dynamic effects between stock market trading volume and returns and volatility for both domestic and cross country markets by using the daily data of the three largest stock markets new york tokyo and london major findings are as follows first trading volume does not granger cause stock market returns on each of three stock markets second there exists a positive feedback relationship between trading volume and return volatility in all three markets third regarding the cross country relationships us financial market variables in particular us trading volume contains an extensive predictive power for uk and japanese financial market variables fourth sub sample analyses show evidence of stronger spillover effects after the 1987 market crash and an increased importance of trading volume as an information variable after the introduction of options in the us and japan

the euro and european financial market dependence a time varying copula model is used to investigate the impact of the introduction of the euro on the dependence between 17 european stock markets during the period 1994 2003 the model is implemented with a gjr garch ma t model for the marginal distributions and the gaussian copula for the joint distribution which allows capturing time varying non linear relationships the results show that within the euro area market dependence increased after the introduction of the common currency only for large equity markets such as in france germany italy the netherlands and spain structural break tests indicate that the increase in financial market dependence started around the beginning of 1998 when euro membership was determined and the relevant information was announced the uk and sweden but not other european countries outside the euro area are found to exhibit an increase in equity market co movement which is consistent with the interpretation that these countries may be expected to join the euro in the future

long and short term dynamic causal transmission amongst international stock markets abstract this paper investigates the dynamic causal linkages amongst nine major international stock price indexes in order to gauge the causal transmission patterns we employ very recent methods of i vector error correction modeling and ii level var modeling with possibly integrated and cointegrated processes advocated by i toda and phillips econometrica 61 1993 1367 and ii toda and yamamoto j econometrics 66 1995 225 respectively the paper illustrates how such methods may be appropriately augmented in a compatible fashion to unearth previously unfounded linkage properties inherent amongst a system of stock price indexes in particular we demonstrate that previous research by using ordinary difference vars ignored an important component of linkages displayed purely over the long run this untapped evidence essentially provides robust and very useful information to international financial analysts and investors at a substantive level results of this study tend to support the contention offered by several studies in the literature of significant interdependencies between the established oecd and the asian markets and also the leadership of the us and uk markets over the short and long run the levels var however illustrate the japanese market s influence as an additional long run leader findings seem to be plausible given that these three markets us uk and japan have consistently contributed over 75 of global stock market capitalization over the major part of the sample under consideration at a methodological level this analysis also provides a primer for the wealth of applied financial econometric research focusing on dynamic causal inference which involve systems containing possibly integrated and cointegrated processes

spillover effects in the global copper futures markets asymmetric multivariate garch approaches this study investigates changes in return and volatility spillovers between the lme comex and the shfe copper futures markets before and after the global financial crisis and after the introduction

work disincentives of workers compensation permanent partial disability benefits evidence for canada this paper examines the impact of workers compensation benefits and expected labour market earnings on the post injury employment status of permanently injured workers permanent partial disability benefits in ontario at the time the data were collected were not related to post injury labour market earnings and can therefore be characterized as having a pure income effect on post injury employment behaviour the estimation results indicate an elasticity of post injury employment to workers compensation permanent disability ben efits of 0 15 evaluated for the mean worker the elasticity of post injury employment to expected post injury labour market earnings is about 0 94 per cent les desincitations au travail des prestations d indemnisation permanente des travailleurs pour incapacite partielle ce memoire examine l impact des prestations d indemnisation des travailleurs et des gains anticipes sur le marche du travail sur le statut d emploi des travailleurs incapacites de maniere permanente les prestations permanentes pour compenser une incapacite partielle n etaient pas reliees aux gains apres l accident en ontario au moment out les donnees ont ete recueillies on peut donc parler d un effet de revenu pur sur le comportement de travail apres l accident les resultats montrent que pour le travailleur moyen l elasticite de l emploi apres l accident par rapport a la prestation d incapacite est de 0 15 d autre part l elasticite de 1 emploi apres l accident par rapport aux gains anticipes sur le marche du travail apres l accident est a peu pres 0 94 pour cent

interdependence and dynamics in currency futures markets a multivariate analysis of intraday data abstract this paper investigates long term interdependencies and short term dynamics in currency futures utilizing intraday data for six major foreign currencies the british pound deutsche mark swiss franc australian dollar canadian dollar and japanese yen lack of cointegration ci among the foreign exchange futures is found to be the prevailing mode of behavior but some temporary deviations from the no ci condition are detected there is a notable overlap between detected ci relationships and the timing of policy changes world events and regime shifts indicating that the observed cis are event driven the robustness of the ci results is checked with respect to variations in the model lag structure data period sample horizon and currency basket grouping impulse response functions irfs reveal that currency markets are in general efficient and absorb new information within the day the interdependence among currencies is found to be asymmetric

explaining co movements between stock markets the case of us and germany abstract we explain co movements between stock markets by explicitly considering the distinction between interdependence and contagion we propose and implement a full information approach on data for us and germany to provide answers to the following questions i is there long term interdependence between us and german stock markets ii is there short term interdependence and contagion between us and german stock markets i e do short term fluctuations of the us share prices spill over to german share prices and is such co movement unstable over high volatility episodes our answers are respectively no to the first question and yes to the second one

intraday volatility in international stock index futures markets meteor showers or heat waves the international transmission of intraday price volatility among the united states united kingdom and japanese stock index futures markets in the period 1988 1994 is investigated in this paper the empirical results based on extreme value estimators and vector autoregression indicate the rapid transmission of information between markets the volatilities of the u s and u k futures markets appear to follow a meteor shower rather than a heat wave type of process this means that these volatilities react to shocks from other markets i e they cannot be described only by their past values however the heat wave hypothesis is not rejected for the japanese market meaning that the shocks to japanese volatility are mostly country specific a multivariate garch model supports the u k and japanese but not the u s results

international diversification through closed end country funds abstract the primary objectives of this paper are to assess the potential of closed end country funds cecfs as vehicles for achieving international diversification at home and to examine the effect of the closed end status of these funds on their investment characteristics the main findings are first cecfs exhibit significant exposure to the u s market factor and act more like u s securities than do their underlying assets second despite these characteristics cecfs retain significant exposure to their local home market factors and provide u s investors with substantial diversification benefits emerging market funds such as brazil mexico and taiwan receive large weights in optimal international portfolios comprised of cecfs implying that these funds can play a unique role in spanning the opportunity set for u s investors third performance evaluations indicate that our sample cecfs generally did not offer significant overseas alphas fourth fund value and net asset value are found to be co integrated for the majority of cecfs from north america and europe but not for those representing the asian emerging markets

disabled workers and wage losses some evidence from workers with occupational injuries using data from the survey of ontario workers with permanent impairments 1989 90 the authors examine the effects of work related disabilities on the wage losses of disabled male workers one important focus of the analysis is whether the size of disabled workers wage losses was affected by whether they remained at or left the job where the accident occurred the authors also estimate the longer term persistence of wage shocks for disabled workers the estimates suggest that wage losses were larger for disabled workers who did not return to work with their time of accident employer than for those who did return with the latter earning 27 more furthermore wages appear to have been more persistent for workers who did not return to their accident employer than for those who did return

the international price transmission in stock index futures markets i introduction numerous studies have investigated market linkages and price transmission mechanisms in major international equity markets employing the analytical framework of the vector autoregression var or its variant the error correction model ecm 1 studies such as von furstenberg and jeon 1989 eun and shim 1989 and koch and koch 1991 focus on the short run dynamic pattern of price transmission others like taylor and tonks 1989 and francis and leachman 1998 are primarily interested in the long run pattern of price transmission more recently an increasing number of studies explore both long and short run patterns of price transmission included in this last set are the works of malliaris and urrutia 1992 arshanapalli and doukas 1993 masih and masih 2001 and bessler and yang 2003 among others this study extends the examination of international price transmission to stock index futures markets the article contributes to the existing literature in three aspects first a relatively new empirical framework is applied to allow for inferences of price transmission at three different time horizons instantaneous the short run and the long run building on recent advances in statistical analysis of causal modeling using directed acyclic graphs dags as in spirtes et al 2000 pearl 1995 2000 and swanson and granger 1997 this study is able to explore the contemporaneous causal pattern underlying the correlations among market innovations the existence of strong contemporaneous correlations among market innovations has been well documented in the united states and international stock markets by agmon 1972 eun and shim 1989 koch and koch 1991 housbrouk 1995 and bessler and yang 2003 it is also well recognized by agmon 1972 849 and eun and shim 1989 246 that contemporaneous correlations among market innovations reflect the phenomenon that new information in one market is transmitted and shared by other markets in contemporaneous time due to immediate response to price changes between markets however more in depth analysis on exactly how instantaneous price transmission among market innovations is conducted in international equity markets has not yet been well addressed in the existing literature although bessler and yang 2003 touch on the issue the necessity of imposing constraints in the spirit of the block recursive structure noted by koch and koch 1991 in the dag analysis of var innovations is proposed and discussed thoroughly in this study second innovation accounting analysis is more thoroughly explored in the study innovation accounting tools i e impulse response analysis and forecast error variance decomposition have been commonly used to summarize the dynamic pattern of price transmission among international financial markets the importance of the factorization of innovations i e var residuals in yielding sound inference has been well acknowledged theoretically by bernanke 1986 sims 1986 and swanson and granger 1997 the application of the dag technique as discussed in swanson and granger 1997 and explained in the next section is further key to innovation accounting analysis in this study the instantaneous price transmission pattern between market innovations as identified by the dag analysis provides a data determined solution to the basic problem of orthogonalization of residuals from the ecm and thus is critical to impulse response analysis or forecast error variance decompositions swanson and granger 1997 argue that compared to the choleski decomposition the dag based structural decomposition is sensible but not subjective because it allows for the properties exhibited by the data although several recent studies such as those by bessler and yang 2003 bessler et al 2003 haigh and bessler forthcoming and yang 2003 have used the dag based structural decomposition in a similar setting the study is the first attempt responding to the suggestion by swanson and granger 1997 364 of investigating the empirical implications of the dag based contemporaneous causal modeling
