stock price dynamics and firm size an empirical investigation we show that after controlling for the effects of bid ask spreads and trading volume the conditional future volatility of equity returns is negatively related to the level of stock price this leverage effect is stronger for small as compared to large firms we also document that while the essential characteristics of the relations between stock price dynamics and firm size are stable the strengths of the relationships appear to change over time a number of empirical studies have documented that stock volatility tends to fall subsequent to an increase in stock prices and rise following a decline in stock prices an observation commonly attributed to the leverage effect as explained by black 1976 leverage can induce future stock volatility to vary inversely with the stock price a fall in a firm s stock value relative to the market value of its debt causes a rise in its debt equity ratio and increases its stock volatility for example black 1976 and christie 1982 use individual securities and french schwert and stambaugh 1987 gallant rossi and tauchen 1990 schwert 1990 and nelson 1991 use market indices to provide evidence consistent with the leverage effect however these papers demonstrate a leverage effect either intertemporally or cross sectionally for some assets relatively little work has examined the intertemporal behavior of individual assets by taking into account conditional heteroskedasticity and changing expected returns in this paper we examine and characterize the cross sectional and temporal relations between stock price dynamics and firm size in particular we investigate the possibility of an inverse relation between future stock volatility and stock price and whether this effect varies across time and or across firms with different market capitalization our study uses the exponential garch egarch formulation of nelson 1991 as a model for the timeseries behavior of individual security returns nonparametric methods are

lender penalty for environmental damage and the equilibrium cost of capital in a model of the lending relationship incorporating both adverse selection and moral hazard we show that increasing the liability of lenders for environmental damage done by their borrowers has a qualitatively ambiguous impact upon interest rates this calls into question the assertion of financial community representatives that such reform will necessarily driveup interest rates and have adverse macroeconomic consequences if it is this fear which is preventing reform then that reluctance may in the case of many classes of pollutant be misplaced the implications of such reform for credit rationing are also explored

balance sheet effects foreign reserves and public policies this paper shows that countries can use foreign reserves to enhance their domestic economies resilience to potential risks from balance sheet effects based on a theoretical model this paper demonstrates that the government can either deploy its foreign reserves to lend in foreign currency to the private sector or increase fiscal spending on domestic goods both these policy tools can remedy the bad equilibrium characterized by large scale domestic currency depreciation and very low aggregate investment but they diverge in how they stabilize the domestic economy and require different minimum amounts of foreign reserves targeted lending works by altering investors expectations of the domestic exchange rate and of firms net worth as long as foreign reserves are sufficient to cover the private sector s external debt this approach eliminates the bad equilibrium without an actual depletion of reserves in contrast fiscal spending increases the demand for domestic goods and affects the relative price leading to domestic exchange rate appreciation that subsequently increases firms net worth and facilitates investment

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

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

international transmission of information evidence from the euroyen and eurodollar futures markets abstract this paper examines the information transmission between japan and the us by using the tokyo euroyen and chicago eurodollar futures these two interest rate futures markets provide a better understanding of international information transmission than stock markets which have been shown to exhibit nonsynchronous trading and market segmentation the results show that traders in tokyo chicago use information that is revealed overnight in chicago tokyo the bivariate egarch t model provides no evidence of volatility spillovers in either direction suggesting that the opening price rapidly reflects foreign information the overall results support the hypothesis that the domestic market efficiently adjusts to foreign news the results are also broadly consistent with the covered interest arbitrage effects

international financial contagion in currency crises abstract this paper examines the role of financial linkages especially through a common creditor in the propagation of emerging market crises during the 1990s using panel probit regressions on 41 emerging market countries it finds that financial linkages played a significant role in the spread of the mexican asian and russian crises the significance of financial linkages emerges after controlling for the role of domestic and external fundamentals trade spillovers and financial weaknesses in the affected countries a strong financial linkage to the crisis country of origin not only substantially raises the probability of contagion but also helps to explain the observed regional concentration of currency crises

global risk aversion and emerging market return comovements abstract utilizing the recently developed measure of global risk aversion by xu 2017 we show that global risk aversion is a significant determinant of international equity correlations consistently across all emerging markets examined the positive effect of risk aversion on emerging market comovements is particularly strong for south africa and turkey and is consistent with contagion effects the results underscore the importance of non cash flow shocks in models of contagion and portfolio risk

tax base variability and procyclical fiscal policy in developing countries abstract based on a sample of 56 countries we show that fiscal policy in the g7 countries appears to be acyclical while fiscal policy in developing countries is procyclical i e fiscal policy is expansionary in good times and contractionary in bad times to explain this puzzle we develop an optimal fiscal policy model in which running budget surpluses is costly because they create pressures to increase public spending given this distortion a government that faces large fluctuations in the tax base as is the case for developing countries will find it optimal to run a procyclical fiscal policy

volatility linkages across three major equity markets a financial arbitrage approach abstract this paper investigates the high frequency behavior of us british and german stock market exuberance using an index provided by standard portfolio arbitrage relationships symmetric and asymmetric multivariate garch models are implemented to quantify international volatility linkages between january 1992 and april 2000 a shift in volatility transmission is detected from may 1997 onwards empirical analysis suggests that equity markets volatility modeling with exuberance indexes is more accurate than modeling with stock returns exuberance volatility comovements across countries are compared with the corresponding return comovements an interpretation of their discrepancy is provided in terms of bond and stock returns international covariation

volatility transmission and volatility impulse response functions in european electricity forward markets using daily data from march 2001 to june 2005 we estimate a var bekk model and find evidence of return and volatility spillovers between the german the dutch and the british forward electricity markets we apply hafner and herwartz 2006 journal of international money and finance 25 719 740 volatility impulse response function virf to quantify the impact of shock on expected conditional volatility we observe that a shock has a high positive impact only if its size is large compared to the current level of volatility the impact of shocks are usually not persistent which may be an indication of market efficiency finally we estimate the density of the virf at different forecast horizon these fitted distributions are asymmetric and show that extreme events are possible even if their probability is low these results have interesting implications for market participants whose risk management policy is based on option prices which themselves depend on the volatility level

conditional heteroscedasticity in time series of stock returns evidence and forecasts this article presents new evidence about the time series behavior of stock prices daily return series exhibit significant levels of second order dependence and they cannot be modeled as linear white noise processes a reasonable return generating process is empirically shown to be a first order autoregressive process with conditionally heteroskedastic innovations in particular generalized autoregressive conditional heteroskedastic garch 1 1 processes fit to data very satisfactorily various out of sample forecasts of monthly return variances are generated and compared statistically forecasts based on the garch model are found to be superior copyright 1989 by the university of chicago

how liable should a lender be the case of judgment proof firms and environmental risk comment recently u s environmental law has shown a tendency toward increased lender liability a model of a potentially judgment proof owner of a firm a lender and a potential victim is developed in which this policy can increase accident frequency and reduce efficiency full partial and zero lender liability rules and a minimum equity requirement are analyzed partial lender liability and an equivalent minimum equity requirement deliver the highest level of efficiency although the former can deliver a higher contribution by the lender to the victim than the latter policy and empirical implications are also discussed copyright 1995 by american economic association

bankruptcy and care choice this article considers the care choice of a potentially bankrupt injurer when care is pecuniary and the legal system is characterized by strict liability i show contrary to previous results that such an injurer may take too little or too much care and that neither injurer care nor victim welfare is necessarily increasing in injurer wealth when injurers behave optimally analysis of an expected cost function demonstrates that injurer expected costs are a concave and increasing function of injurer assets a result suggesting applications to the study of vertical relationships and markets for agents

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

large dynamic covariance matrices second moments of asset returns are important for risk management and portfolio selection the problem of estimating second moments can be approached from two angles time series and the cross section in time series the key is to account for conditional heteroscedasticity a favored model is dynamic conditional correlation dcc derived from the arch garch family started by engle 1982 in the cross section the key is to correct in sample biases of sample covariance matrix eigenvalues a favored model is nonlinear shrinkage derived from random matrix theory rmt the present article marries these two strands of literature to deliver improved estimation of large dynamic covariance matrices supplementary material for this article is available online

volatility spillovers across international swap markets the us japan and the uk abstract this paper examines volatility spillovers across the three major international swap markets namely the us japan and the uk we apply a multivariate var egarch model by incorporating the slope of term structure and corporate spread variables to capture the time varying nature of swap spread volatility across countries our empirical findings show that the changes in the swap spreads are significantly influenced by the slope of term structure variable in all three currencies we find that the us swap market has a major influence on the japanese and uk swap markets but not vice versa we also find that reciprocal spillovers exist between japanese and the uk swap markets in almost all cases the degree of volatility persistence is fairly strong and in many cases we find asymmetric volatility spillovers across maturity and country

from great depression to great credit crisis similarities differences and lessons the great depression of the 1930s and the great credit crisis of the 2000s had similar causes but elicited strikingly different policy responses while it remains too early to assess the effectiveness of current policy it is possible to analyse monetary and fiscal responses in the 1930s as a natural experiment or counterfactual capable of shedding light on the impact of current policies we employ vector autoregressions instrumental variables and qualitative evidence for 27 countries in the period 1925 39 the results suggest that monetary and fiscal stimulus was effective that where it did not make a difference it was not tried they shed light on the debate over fiscal multipliers in episodes of financial crisis they are consistent with multipliers at the higher end of those estimated in the recent literature and with the argument that the impact of fiscal stimulus will be greater when banking systems are dysfunctional and monetary policy is constrained by the zero bound miguel almunia agustin benetrix barry eichengreen kevin h o rourke and gisela rua

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

dynamic causality between the u s stock market the chinese stock market and the global gold market implications for individual investors diversification strategies this paper proposes a generalization of the prior var and egarch model to explore the linkage between returns and volatility transmissions in the u s stock market the chinese stock market and th

monetary policy options for mitigating the impact of the global financial crisis on emerging market economies though the hypothesis that exchange rate regimes fully predetermine monetary policy in the face of external shocks hardly finds any advocates on theoretical ground it has crept in the most of empirical research this study adopts a more discerning empirical approach that looks at monetary policy tools used in order to accommodate the recent financial crisis we investigated the gdp growth in 45 emerging market economies in the most intense phase of the crisis and found out that there is no clear difference in the growth performance between countries at the opposite poles of the exchange rate regime spectrum depreciation cum international reserve depletion outperforms the other policy options especially the rise in the interest rate spread we discovered certain complementarities between the information on the policy option and on exchange rate regime taking into account non gaussian settings we decided to use quantile regression which provide in addition more complete picture of relationship between the covariates and the distribution of the gdp growth

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

have the gipsi settled down breaks and multivariate stochastic volatility models for and not against the european financial integration we investigate the integration of the european peripheral financial markets with germany france and the uk using a combination of tests for structural breaks and return correlations derived from several multivariate stochastic volatility models our findings suggest that financial integration intensified in anticipation of the euro further strengthened by the emu inception and amplified in response to the 2007 2008 financial crisis hence no evidence is found of decoupling of the equity markets in more troubled european countries from the core interestingly the uk despite staying outside the emu is not worse integrated with the gipsi than germany or france 2013 elsevier b v

price and volatility spillovers in scandinavian stock markets abstract new evidence is provided on price and volatility spillovers among the danish norwegian swedish and finnish stock markets the impact of good news market advances and bad news market retreats is described by a multivariate exponential generalized autoregressive conditionally heteroskedastic egarch model volatility transmission is asymmetric spillovers being more pronounced for bad than good news significant price and volatility spillovers exist but they are few in number

overview of the special issue on policy implications of and lessons from the global financial crisis this paper reviews the special issue policy implications of and lessons from the global financial crisis and its themes global liquidity and the use of international reserves real and financial economic patterns before and during the global financial crisis

on crises contagion and confusion abstract since the tequila crisis of 1994 1995 the asian flu of 1997 and the russian virus of 1998 economists have been busy producing research on the subject of contagion yet few studies have examined empirically through which channels the disturbances are transmitted if there are indeed fundamental reasons for the spillovers we observe we attempt to fill this gap by analyzing how both trade links and the largely ignored financial sector links influence the pattern of fundamentals based contagion we examine the role of international bank lending the potential for cross market hedging and bilateral and third party trade in the propagation of crises

the benefits of extended liability we characterize the optimal regulation of a firm that undertakes an environmentally risky activity this firm the agent is protected by limited liability and bound by contract to a stakeholder the principal the level of safety care exerted by the agent is nonobservable this level of care depends both on the degree of incompleteness of the regulatory contract and on the allocation of bargaining power between the principal and the agent increasing the wealth of the principal that can be seized upon an accident has no value when private transactions are regulated but might otherwise strictly improve welfare an incomplete regulation supplemented by an ex post extended liability regime can sometime achieve the second best

stock market volatility and business cycle evidence from linear and nonlinear causality tests this paper investigates the relationship between stock market volatility and the business cycle in four major economies namely the us canada japan and the uk we employ both linear and nonlinear bivariate causality tests and we further conduct a multivariate analysis to explore possible spillover effects across countries our results suggest that there is a bidirectional causal relationship between stock market volatility and the business cycle within each country and additionally reveal that the recent financial crisis plays an important role in this context finally we identify a significant impact of the us on the remaining markets

us trade and inventory dynamics we examine the source of the large fall and rebound in us trade in the recent recession while trade fell and rebounded more than expenditures or production of traded goods we find that relative to the magnitude of the downturn these trade fluctuations were in line with those in previous business cycle fluctuations we argue that the high volatility of trade is attributed to more severe inventory management considerations of firms involved in international trade we present empirical evidence for autos as well as at the aggregate level that the adjustment of inventory holdings help explain these fluctuations in trade

volatility transmission in emerging european foreign exchange markets abstract this paper studies the dynamics of volatility transmission between central european ce currencies and the eur usd foreign exchange using model free estimates of daily exchange rate volatility based on intraday data we formulate a flexible yet parsimonious parametric model in which the daily realized volatility of a given exchange rate depends both on its own lags as well as on the lagged realized volatilities of the other exchange rates we find evidence of statistically significant intra regional volatility spillovers among the ce foreign exchange markets with the exception of the czech and prior to the recent turbulent economic events polish currencies we find no significant spillovers running from the eur usd to the ce foreign exchange markets to measure the overall magnitude and evolution of volatility transmission over time we construct a dynamic version of the diebold yilmaz volatility spillover index and show that volatility spillovers tend to increase in periods characterized by market uncertainty

the rising resilience of emerging market and developing economies summary economic performance in many emerging market and developing economies emdes improved substantially over the past 20 years in the past decade emdes spent more time in expansion and had smaller downturns than advanced economies for the first time we document the history of emdes resilience over the past 60 years and investigate what factors have been associated with it we find that their improved performance since the 2000s is accounted for by both good policies and a lower incidence of external and domestic shocks better policies account for about three fifths of their improved resilience while less frequent shocks account for the remainder

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

modelling the choice between regulation and liability in terms of social welfare using a formal political economy model with asymmetric information we illustrate the conditions under which an environmental protection system based on extending liability to private financiers is welfare superior inferior or equivalent to a system based on an incentive regulatory scheme subject to capture by the regulatees we explicitly consider the following factors the cost of care and its efficiency in reducing the probability of an environmental accident the social cost of public funds the net profitability of the risky activities the level of damages and the regulatory capture bias we characterize in such a parameter space the regions where one system dominates the other jel classification d82 k32

managers investors and crises mutual fund strategies in emerging markets the authors address the trading strategies of mutual funds in emerging markets the data set they develop permits analyses of these strategies at the level of individual portfolios a methodologically novel feature of their analysis they disentangle the behavior of fund managers from that of investors for both managers and investors they strongly reject the null hypothesis of no momentum trading funds momentum trading is positive they systematically buy winners and sell losers contemporaneous momentum trading buying current winners and selling current losers is stronger during crises and stronger for fund investors than for fund managers lagged momentum trading buying past winners and selling past losers is stronger during noncrises and stronger for fund managers investors also engage in contagion trading selling assets from one country when asset prices fall in another these findings are based on data about mutual funds that represent only 10 percent of the market capitalization in the countries considered were it a larger share of the market finding counterparties for their trades the investors who buy when they sell and sell when they buy would be difficult and the premise that funds respond to contemporaneous returns rather than causing them would become tenuous

oil prices and equity returns in the bric countries this paper measures the level by which global oil price returns influence the stock returns and volatility in the bric equity markets and observes the time varying conditional correlation between bric equity returns and oil price returns the study concludes that the level of impact of oil price returns on equity returns and volatility in the bric countries depends on the extent to which these countries are net importers or net exporters of oil it also concludes that despite the aggressive economic growth of the bric countries in the past 25 years the volatility of stock returns in these economies does not have a significant impact on the volatility of global oil price returns

volatility spillover and multivariate volatility impulse response analysis of gfc news events abstractthis article applies two measures to assess spillovers across markets the diebold and yilmaz s 2012 spillover index and the hafner and herwartz s 2006 analysis of multivariate garch models using volatility impulse response analysis we use two sets of data daily realized volatility rv estimates taken from the oxford man rv library for the s p500 and the ftse plus 10 years of daily returns series for the new york stock exchange index and the ftse 100 index both data sets capture both the global financial crisis gfc and the subsequent european sovereign debt crisis esdc the spillover index captures the transmission of volatility to and from markets plus net spillovers the volatility impulse responses virf have to be calibrated to conditional volatility estimated at a particular point in time we explore the impact of three different shocks the onset of the gfc the height of the gfc and the impact of the esdc our modelling includes leverage and asymmetric effects applying a mu

from pigou to extended liability on the optimal taxation of externalities under imperfect financial markets an important contribution of economics to public policy rests on the precept that price signals should force producers of externalities to internalize the welfare of other economic agents pigou 1920 s celebrated insight on the taxation of externalities provided an intellectual foundation for a variety of policies from pollution taxes permits to experience rating pigovian taxation s policy appeal is limited if the polluter has insufficient resources to pay the damage when it occurs to defend pigovian taxation in the presence of judgment proof agents its proponents point at the many institutions extending liability to third parties yet little is known about the validity of pigou s analysis in this context the paper analyzes the costs and benefits of extended liability and investigates whether full internalization is called for in the presence of agency costs between potential polluters and providers of guarantees its contribution is two fold it first shows that the better the firms corporate governance and the stronger their balance sheet the more closely taxes should track the corresponding externality it then develops the first analysis of extended liability when guarantors themselves may be judgment proof and the extension of liability may give rise to further externalities relatedly it derives the curvature of the optimal taxation of externalities in a multiplant firm

evolution in dynamic linkages across daily national stock indexes abstract this article investigates how dynamic linkages among the daily rates of return of eight national stock indexes have evolved since 1972 a dynamic simultaneous equations model is estimated to describe the contemporaneous and lead lag relationships across national equity markets over three different years 1972 1980 and 1987 results reveal growing market interdependence within the same geographical region over time while there are many significant intermarket relationships within the same 24 hour period there are few significant lagged responses across markets beyond 24 hours this suggests a high degree of international market efficiency furthermore japan s market influence has been growing to rival that of the usa

self reporting of pollution and the firm s behavior under imperfectly enforceable regulations abstract motivated by the nature of u s laws a model is developed for a firm that maximizes expected profit and faces imperfectly enforceable pollution standards with imperfectly enforceable reporting requirements some previous models of imperfectly enforceable standards and taxes are special cases of this general mode when the fine for violating the pollution standard is linear in excess pollution the form will equate the marginal cost of control to the marginal fine rate and thus actual pollution will be insensitive to enforcement parameters related to under reporting the more complex comparative statics that exist when the fine is non linear are analyzed and comparisons with other models are made

on the exposure of the bric countries to global economic shocks the financial crisis led to a deep recession in many industrial countries while large emerging countries recovered relatively quickly from the financial crisis their performance deteriorated in the last years despite the modest recovery in advanced economies the higher divergence of business cycles is closely linked to the chinese transformation during the crisis the chinese fiscal stimulus prevented a decline in gdp growth not only in that country but also in resource rich economies the chinese shift to consumption driven growth led to a decline in commodity demand and the environment became more challenging for many emerging markets this view is supported by bayesian vars specified for the bric brazil russia india and china countries the results reveal a strong impact of international variables on gdp growth in contrast to the other countries china plays a crucial role in determining global trade and oil prices hence the change in the chinese growth strategy puts additional reform pressure on countries with abundant natural resources

hourly volatility spillovers between international equity markets abstract this paper examines the timing of mean and volatility spillovers between new york and london equity markets using an arch model it is found that the evidence of volatility spillovers between these markets is minimal and have a duration which lasts only an hour or so the most significant effects surround the movement of share prices around the new york opening but these results are not strong several new arch models are estimated including an asymmetric or leverage model and a non linear model which allows big shocks to have a different impact from small shocks

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

liability transfers an economic assessment of buyer and lender liability abstract this paper examines the conditions under which it is efficient to transfer liability for contamination of a given piece of property from the seller to the buyer at the time of sale and then for debt financed sales for which there is a foreclosure subsequently to the lender who has financed the purchase we identify two key potential sources of inefficiency which depend on the relative probabilities that the parties will be judgment proof at the time liability is imposed the results suggest that the efficiency effects of liability transfers will depend on the relative magnitudes of these two sources of inefficiency

correlations and volatility spillovers between oil prices and the stock prices of clean energy and technology companies abstract in this paper multivariate garch models are used to model conditional correlations and to analyze the volatility spillovers between oil prices and the stock prices of clean energy companies and technology companies four different multivariate garch models bekk diagonal constant conditional correlation and dynamic conditional correlation are compared and contrasted the dynamic conditional correlation model is found to fit the data the best and generates results showing that the stock prices of clean energy companies correlate more highly with technology stock prices than with oil prices on average a 1 long position in clean energy companies can be hedged for 20 cents with a short position in the crude oil futures market

cross country experiences and policy implications from the global financial crisis the financial crisis of 2007 2008 is rooted in a number of factors some common to previous financial crises others new analysis of post crisis macroeconomic and financial sector performance for 58 advanced countries and emerging markets shows a differential impact of old and new factors factors common to other crises like asset price bubbles and current account deficits help to explain cross country differences in the severity of real economic impacts new factors such as increased financial integration and dependence on wholesale funding help to account for the amplification and global spread of the financial crisis our findings point to vulnerabilities to be monitored and areas of needed national and international reforms to reduce risk of future crises and cross border spillovers they also reinforce a sad state of knowledge much of how crises start and spread remains unknown stijn claessens giovanni dell ariccia deniz igan and luc laeven

stock returns and volatility an empirical study of the uk stock market abstract attempts to quantify the relationship between stock returns and volatility have produced conflicting conclusions in recent u s studies our paper examines this issue in the u k context for the first time using daily weekly fortnightly and monthly returns on the financial times all share index from january 1965 to december 1989 volatility estimates are obtained from monthly sample variances and arch models expected returns are shown to have had a positive though not statistically significant relationship with expected volatility the relationship between the unexpected components of the returns and volatility series is less clear we find evidence for a negative relationship but only when volatility expectations are represented by standard deviations

liability and large scale long term hazards this paper analyzes the application of liability to large scale long term hazards the key features distinguishing such hazards are the long temporal separation between exposure to a hazard and disease and the large damages when injuries finally emerge the large scale of damages creates a strong incentive to avoid liability payments and the long temporal separation creates numerous avenues through which parties can avoid paying possible damage awards the analysis focuses on the incentive to avoid paying damages by vertically divesting production tasks associated with serious occupational risks such divestiture can lower liability costs if the small firm operating the risky stage goes out of business before latent injuries emerge or has insufficient assets to pay damages and declares bankruptcy when suits are filed the paper then presents an empirical regression analysis of small firm entry into the u s economy between 1967 and 1980 the period in which liability laws were changing the point estima

modeling heteroscedasticity in daily foreign exchange rates this article estimates autoregressive conditionally heteroscedastic arch and generalized arch garch models for five foreign currencies using 10 years of daily data a variety of arch and garch specifications a number of nonnormal error densities and a comprehensive set of diagnostic checks it finds that arch and garch models can usually remove all heteroscedasticity in price changes in all five currencies goodness of fit diagnostics indicate that exponential garch with certain nonnormal distributions fits the canadian dollar extremely well and the swiss franc and the deutsche mark reasonably well only one nonnormal distribution fits the japanese yen reasonably well none fit the british pound

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

intraday linkages between the spanish and the us stock markets evidence of an overreaction effect this paper focuses on short term information transmission between the us stock market properly the dow index and the main spanish stock index ibex 35 in its early and final hours we follow the approaches of lin engle and ito 1994 susmel and engle 1994 and baur and jung 2005 who use a garch model to analyze the influence of the previous daytime and overnight returns and volatility of the dow upon the overnight returns and daytime returns of the ibex from open to 3 30 and from 3 30 to close the results suggest that the spanish stock market usually has a low price movement till wall street opens additionally they indicate that the spanish market reacts quickly to the news basically in the first four minutes following the opening of the us market furthermore we find the existence of an overreaction effect during the two hours before the closing of the spanish market

dynamic interdependence of sovereign credit default swaps in brics and mist countries abstractthis article examines the interactions of emerging markets sovereign credit default swaps cds using a generalized vector autoregressive framework and principal component analysis we find significant spillover effects within the two groups of emerging markets under study using the principal component analysis we show that global financial market factors are important drivers of brics and mist sovereign cds spreads variability focusing on the forecast error variance decomposition most of the spillover effects are documented among the emerging markets cds brazil and mexico contribute the largest net directional spillovers to the other emerging markets studied highlights there exist significant cds spillover effects for mist and brics countries mexico dominates the spillover effects within the mist group while brazil dominates the spillover effects within the brics group as determined by principal component analysis global financial market factors are important drivers of brics and mist sov

when in peril retrench testing the portfolio channel of contagion abstract the impact of past gains and losses on international investors risk aversion is an important factor in the propagation of financial shocks across countries we first present a stylized model illustrating how changes in investors risk aversion affect portfolio decisions and stock prices we then examine empirically the behavior of international mutual funds when funds returns are below average they reduce their exposure to countries in which they were overweight and vice versa an index of financial interdependence that reflects the extent to which countries share overexposed funds helps explain the pattern of stock market comovement across countries and the pattern of contagion during crises

meteor showers or heat waves heteroskedastic intra daily volatility in the foreign exchange market this paper seeks to explain the causes of volatility clustering in exchange rates careful examination of intra daily exchange rates provides a test of two hypotheses heat waves and meteor showers the heat wave hypothesis is that the volatility has only country specific autocorrelation alternatively the meteor shower is a phenomenon of intra daily volatility spillovers from one market to the next using the garch model to specify the heteroskedasticity across intra daily market segments we find that the empirical evidence is generally against the null hypothesis of the heat wave using a volatility type of vector autoregression we examine the impact of news in one market on the time path of per hour volatility in other markets

dynamic correlation and equicorrelation analysis of global financial turmoil evidence from emerging east asian stock markets abstractthis study investigates the dynamic conditional correlations dccs between eight emerging east asian stock markets and the us stock market and analyses the dynamic equicorrelation among these nine stock markets we find a significant increase in the conditional correlations and equicorrelation in the first phase of the global financial crisis we refer to this finding as contagion from the us stock market to the emerging east asian markets we also find an additional significant process of increasing correlations and equicorrelation herding in the second phase of the global financial crisis further we employ two new models namely dccx mgarch a dcc multivariate garch model with exogenous variables and decox mgarch a dynamic equicorrelation multivariate garch model with exogenous variables to identify the channels of contagion we find that an increase in the vix index increases the conditional correlations and equicorrelation while increases in ted spreads decrease the conditional corre

why do emerging economies borrow short term the authors argue that emerging economies borrow short term due to the high risk premium charged by international capital markets on long term debt they first present a model where the debt maturity structure is the outcome of a risk sharing problem between the government and bondholders by issuing long term debt the government lowers the probability of a liquidity crisis transferring risk to bondholders in equilibrium this risk is reflected in a higher risk premium and borrowing cost therefore the government faces a tradeoff between safer long term borrowing and cheaper short term debt second the authors construct a new database of sovereign bond prices and issuance they show that emerging economies pay a positive term premium a higher risk premium on long term bonds than on short term bonds during crises the term premium increases with issuance shifting toward shorter maturities this suggests that changes in bondholders risk aversion are important to understand emerging market crises

cross country causes and consequences of the crisis an update abstract we update rose and spiegel forthcoming rose and spiegel 2010 and search for simple quantitative models of macroeconomic and financial indicators of the great recession of 2008 09 we use a cross country approach and examine a number of potential causes that have been found to be successful indicators of crisis intensity by other scholars we check a number of different indicators of crisis intensity and a variety of different country samples while countries with higher income and looser credit market regulation seemed to suffer worse crises we find few clear reliable indicators in the pre crisis data of the incidence of the great recession countries with current account surpluses seemed better insulated from slowdowns

how resilient and countercyclical were emerging economies to the global financial crisis during the crises of the 1990s emerging economies usually lacked the policy tools to deal with external shocks that were available to advanced economies worldwide turbulent episodes found most emerging economies unable to perform countercyclical policies and in many cases their own vulnerabilities and poor institutional frameworks amplified negative external shocks leading to sharper recessions this paper shows that the 2008 2009 global financial crisis represents a structural break in the way emerging economies conduct their policies with more countercyclical policies pursued before and during the global crisis moreover breaking with the past emerging economies did not fall more than developed economies during the global financial crisis thus becoming more similar to developed economies the resilience of emerging economies during the 2008 2009 crisis might be partly attributed to a combination of sounder macroeconomic and financial policy frameworks with a shift towards safer domestic and international financial stances

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

fiscal and monetary policies and the cost of sudden stops abstract this article investigates the effects of monetary and fiscal policies on output growth during sudden stop balance of payments crisis in emerging markets and developing countries sudden stops in capital flows and subsequent deep recessions are a frequent occurrence in these countries but there is no professional consensus and little systematic empirical evidence shedding light on the macroeconomic policy mix most likely to limit output losses during these episodes to address this issue we investigate 83 sudden stop crisis in 66 countries using a baseline empirical model to control for the various determinants of output losses during sudden stops we measure the marginal effects of policy on output losses and find strong evidence that monetary tightening rise in the discount rate or unsterilized rise in international reserves and discretionary fiscal contraction are significantly correlated with larger output losses following a sudden stop fiscal expansion is associated with smaller output losses following a sudden stop but monetary expansion has no discernable effect the macroeconomic policy mix associated with the least output loss during a sudden stop financial crisis is a discretionary fiscal expansion combined with a neutral monetary policy

information transmission between the nasdaq and asian second board markets abstract in the 1980s and early 1990s the nasdaq s success helped to prompt singapore sesdaq japan jasdaq taiwan taisdaq and south korea kosdaq to set up or formalize their own second board markets in 1999 malaysia mesdaq and hong kong gem followed suit given the growing importance of these second board markets we examine whether there is any evidence of spillovers from nasdaq returns and volatilities to asian second board market returns and volatilities after controlling for spillovers from the nyse and whether these cross country spillovers are strong relative to domestic spillovers from the corresponding main board markets we employ egarch models dynamic causality tests and var based forecast error decompositions using daily data of a recent sample period that includes the asian financial crisis of 1997 and continues until april 20 2001 there is strong evidence of lagged returns and volatility spillovers from the nasdaq market to the asian second board markets when we exclude contemporaneous main board market returns there is also strong evidence of contemporaneous and lagged returns and volatility spillovers from the local main board markets to the corresponding second board markets however even in the presence of contemporaneous main board market returns there are substantial spillovers from the lagged nasdaq returns and volatilities to asian second board market returns and volatilities these findings are not sensitive to whether we use us dollar based data or local currency based data given the difference in the trading hours between the nasdaq and asian stock markets we use available intra day return data and canadian return data the findings seem quite robust there is substantial information spillover from the nasdaq to the asian and canadian second board markets these findings indicate the existence of a substantial cross country industry effect or meteor shower effect as well as a domestic market effect or heat wave effect and imply that both country diversification and industry diversification are important

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

globalization and developing countries a shrinking tax base abstract this paper evaluates the impact of globalisation on tax bases of countries at varying stages of development we see globalisation as a process that induces countries to embrace greater trade and financial integration this in turn should shift their tax revenue from easy to collect taxes tariffs and seigniorage towards hard to collect taxes value added and income taxes we find that trade and financial openness have a positive association with the hard to collect taxes and a negative association with the easy to collect taxes

integrated dynamic models for hedging international portfolio risks abstract we develop scenario based stochastic programming models for hedging the risks of international portfolios using options the models provide increasing level of integration in managing market and foreign exchange fx risks we start with a single stage model with currency options for selective hedging of fx risks while market risk is addressed through diversification we add stock options to hedge market risks and add quantos and currency options to develop an integrated model using an innovative method to price quantos on the scenario tree underpinning the stochastic program the models are extended to multi stage settings backtesting on market data over a 14 year period that includes the global financial crisis of 2008 we demonstrate the effectiveness of taking increasingly integrated views of risk management simultaneous hedging of market and fx risks using stock and currency options has the best ex post performance the differences are economically significant and statistical significance is established through rigorous hypothesis testing the models are particularly effective during the crisis test results show that two stage models outperform their single stage counterparts regardless of the hedging strategy

diversifying away the risk of war and cross border political crisis this paper investigates the behavior of crude oil prices government bonds and stock market indices around outbreaks of severe international crises and wars using a constant mean return event study we show that these events are associated with positive and significant abnormal returns on oil and bonds which means that these two asset classes can potentially shelter shareholders from plummeting equity values during international crises a formal safe haven analysis confirms this insight such price movements may reflect a reallocation of funds across asset classes in response to the events as well as shifts in the demand for oil due to precautionary speculative and military motives we also calculate the weights for optimal portfolios which could provide insurance against conflict risk
