a theory of trading volume a theory of trading volume is developed based on assumptions that market agents frequently revise their demand prices and randomly encounter potential trading partners the model describes two distinct ways informational events affect trading volume one is consistent with conjectures made by empirical researchers that investor disagreement leads to increased trading but the observation of abnormal trading volume does not necessarily imply disagreement and volume can increase even if investors interpret the information identically if they also have had divergent prior expectations simulation tests support the model and are used to contrast the random pairing environment with costless market clearing volume is lower in the costly market and volume increases caused by an informational event persist after the event period this is consistent with existing empirical evidence and suggests that markets do not immediately clear all orders or that investors have demands to recontract

are german money market rates well behaved abstract we test the expectations hypothesis eh of the term structure of interest rates for the german money market at the short end of the maturity spectrum using a variety of metrics and on balance we argue that the results tend to broadly support the hypothesis we utilise monthly data on pure discount bonds with a maturity from 1 to 12 months over the period of 1976 to 1993 the var methodology is used to forecast future interest rates which under the eh results in a set of cross equation restrictions as well as tests based on the correspondence between the best forecast referred to as the theoretical spread and the actual spread the var methodology allows explicit consideration of potential non stationarity in the data as do our tests based on the cointegration literature we also perform more conventional tests based on applying the rational expectations re hypothesis in a single equation framework our relatively favourable results for the eh are in sharp contrast to those found in studies using us data and this we attribute in part to the policy of sustained credible monetary targeting by the bundesbank

fractional integration and the volatility of uk interest rates we find that short rates are more nonstationary than longer rates and that differences in conditional volatility exist between different maturities therefore their dynamics may be both maturity specific and country specific and any a priori generalizing assumptions may be misleading

bounds on contingent claims based on several assets abstract in 1987 lo derived an upper bound on the price of a european call option on a single asset lo s bound depends only on the mean and variance of the terminal asset price and is termed a semi parametric bound this paper derives similar semi parametric bounds on a european call on the maximum of any number of assets a distribution free bound for the price of this option is obtained the bound depends only on the means and covariance matrix of the returns on n underlying assets the bound is obtained by optimizing over the entries of a positive definite matrix a this can be accomplished by a technique known as semidefinite programming we demonstrate the methodology using two specific applications the first concerns the valuation of a european call option on the maximum of several assets this is known as an outperformance option and is of some practical interest the second application concerns the valuation of a discretely adjusted lookback option these lookback options are of interest in connection with certain equity annuity insurance products

the market reaction to international cross listings evidence from depositary receipts abstract this paper examines the stock price impact of international dual listings the sample consists of 181 firms from 35 countries that instituted their first depositary receipt program over the period 1985 1995 the market reaction to a depositary receipt program is larger in magnitude and more pervasive than previously reported the stock price reaction is related to choice of exchange geographical location i e emerging or developed markets and avenues for raising equity capital i e public versus private offerings

measures of fit for rational expectations models this survey provides a detailed description of some of the recent theoretical and empirical literature on rational expectations econometrics the survey pays special attention to non stationarity of the data and to the various methods for evaluating rational expectations models that have been developed as alternatives to the classical statistical approach of testing overidentifying restrictions these methods have become very popular and widely used in empirical research we provide an illustration using danish stock market data and we summarize the many results obtained recently using these measures in areas as diverse as stock prices the term structure of interest rates exchange rates consumption and saving the balance of payments tax smoothing hyperinflation and linear quadratic adjustment cost models for inventories labour demand and money demand

asset pricing and dual listing on foreign capital markets a note international capital flows can be hampered by a variety of barriers such as transaction costs information costs and legal restrictions these barriers can be severe enough to produce segmentation of capital markets along national borders thereby producing incentives for firms to adopt financial policies that can effectively reduce the associated negative effects according to stapleton and subrahmanyam 6 p 313 dual listing of the firm s securities on foreign capital markets is one such policy 1 however adoption of this policy will bring forth asset pricing adjustments the purpose of this note is to provide and analyze a closed form solution to the equilibrium asset pricing problem that arises in this situation 2 once the solution is obtained comparative statics are provided 3 the model presented assumes that one of the domestic securities is dually listed on a foreign capital market while none of the foreign securities is dually listed on the domestic capital market this scenario often characterizes the initial stages of capital market integration in which a country with relatively scarce capital or a relatively underdeveloped capital market allows a small number of domestic securities or a fund of domestic securities to be listed on a foreign capital market while simultaneously forbidding its citizens to invest in foreign securities this point can be illustrated by the emergence of a variety of country funds in the u s capital market such as the japan fund in the 1960 s the

replicating options with positions in stock and cash in most situations of practical relevance the price behavior of a call option is very similar to a combined position involving the underlying stock and borrowing the call price and the stock price will change in the same direction the effect on the call price of a one dollar change in the stock price however will depend on the current price of the stock the number of shares of stock in the replicating portfolio must equal the slope of the call price curve at that price when the call is deep out of the money i e when the stock price is much lower than the striking price a one dollar change in the stock price has little effect on the call price when the stock price is equal to the striking price a one dollar change in the stock price produces roughly a half dollar change in the call price if the stock price rises until the call is deep in the money a one dollar move in the stock price results in nearly a one dollar move in the call price because the call price behaves this way we must revise

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

the persistence in volatility of the us term premium 1970 1986 abstract this paper examines the persistence of the volatility of the risk premia for excess holding period returns of the term structure using a garch m model of the conditional variance the finding of a high degree of persistence cannot be sustained once allowance is made for a structural break in the unconditional variance caused by a change in the operation of us monetary policy during 1979 1982

do stationary risk premia explain it all evidence from the term structure abstract predictable variations in excess returns have often been attributed to the presence of time varying risk premia in this paper we use an insight based upon new techniques from time series analysis to test whether stationary risk premia can alone explain the behavior of excess returns to long bonds relative to rolling over short rates surprisingly we reject this hypothesis using u s t bill returns we then show that either permanent shocks to the risk premia and or rationally anticipated shifts in the interest rate process could produce anomalous results

markov switching models rational expectations and the term structure of interest rates in order to evaluate the efficiency of the monetary transmission mechanism we develop the formulas for testing rational expectations theory in the term structure of interest rates with var models of stochastically switching regimes in which all the parameters are regime dependent these formulas are obtained for the strict version of rational expectations as well as for the case where measurement errors are assumed in the expectations relationship they are extensible to other contexts that involve variables linked by rational expectations behaviours the testing procedure is implemented on interest rates of the spanish inter bank money market measurement errors must be assumed to find signs favourable to the theory

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

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

global and local information asymmetries illiquidity and sec rule 144a regulation s the case of indian gdrs abstract between 1992 and 1997 indian firms were the most frequent issuers of equity backed global depositary receipts gdrs governed by the sec s rule 144a and regulation s they also accounted for the highest dollar volume home market stock price responses to these issues are consistent with the hypotheses that gdrs enable firms to resolve two forms of information asymmetry 1 an asymmetry between issuing firms and international investors that results from market segmentation and 2 an asymmetry between indian firms and home market investors that resembles asymmetries that help explain abnormal returns in equity private placements by us firms our evidence suggests that gdr issuance can increase investors recognition of underlying shares even if there are no liquidity enhancements and even if disclosure requirements are not as demanding as those imposed on foreign firms whose depositary receipts trade in public us markets

the expectations hypothesis of the term structure the uk interbank market using a high quality weekly data set the author provides several tests of the expectations hypothesis using the vector autoregression and cointegration methodologies for several maturities between one week and twelve months for the u k interbank market on the basis of the johansen cointegration analysis there appears to be a break in the term structure when both the six month and twelve month maturities are included as a pair the latter may be due to either the presence of liquidity constraints or market segmentation or a time varying term premium all of which would invalidate the assumptions underlying the expectations hypothesis the author provides some tentative explanations of these diverse results copyright 1996 by royal economic society

the effect of market segmentation and illiquidity on asset prices evidence from exchange listings this article documents the effect on share value of listing on the new york stock exchange and reports the results of a joint test of merton s 1987 investor recognition factor and amihud and mendelson s 1986 liquidity factor as explanations of the change in share value we find that during the 1980s stocks earned abnormal returns of 5 percent in response to the listing announcement and that listing is associated with an increase in the number of shareholders and a reduction in bid ask spreads cross sectional regressions provide support for both investor recognition and liquidity as sources of value from exchange listing the effect on share value of listing on the new york stock exchange nyse by over the counter otc stocks has been the focus of empirical investigation by scholars and practitioners for at least 50 years the consensus conclusion is that an nyse listing is or at least has been associated with a significant increase in share price streetlore has historically attributed this increase in value to the increased investor recognition that is believed to accompany listing on a major exchange until recently this investor recognition explanation has lacked a rigorous analytical foundation merton 1987 fills this void with a model of capital market equilibrium with incomplete information to develop his model merton adopts most of the assumptions of the original sharpe lintner mossin capital asset pricing model capm but relaxes the assumption of equal information across investors he further assumes that investors invest only in the those securities of which they are aware 2 with this modification to the original capm framework merton derives a model in which expected returns increase with systematic risk firm specific risk and relative market value and decrease

benchmarking the expectations hypothesis of the interest rate term structure an analysis of cointegration vectors i test cointegration restrictions that are consistent with the expectations hypothesis of the term structure by employing the full information maximum likelihood methods developed by johansen yield curves appear to be the result of cointegration among interest rates the cointegration vectors that best describe the long term impact of interest rate levels on interest rate changes can often be written as linear combinations of interest rate spreads there is however difficulty in keeping short term yields in such a restricted cointegrated system with other interest rates short term speculative returns from long term bonds do not conform to the expectations hypothesis

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

an empirical note on the term structure and interest rate stabilization policies the expectations theory of the term structure of interest rates supplemented by the rational expectations and time invariant risk premium assumption implies that the spread between the long and the short rate has in general predictive power for the short rate this implication was consistently rejected in recent studies shiller campbell and schoenholtz 1983 fama 1984 mankiw and summers 1984 with data at the short end of the maturity spectrum threeand six month treasury bills time variations of the risk premium which are probably important for the behavior of the yield on long term bonds are not an entirely satisfactory explanation for these findings in a more recent article of mankiw and miron 1986 who analyzed quarterly data for threeand six month interest rates over the period 1890 1979 an interesting new explanation for the failure of the expectations theory emerged they showed that the spread had substantial predictive power for changes in the short rate in the period before the founding of the federal reserve 1890 1914 whereas for all other periods considered 1915 1933 1934 1951 1951 1958 and 1959 1979 the spread did not help to predict the short rate thus mankiw and miron suggested that the rejection of the expectations theory with recent data is a consequence of the commitment of the federal reserve to stabilize interest rates resulting in random walk behavior of the short rate under these circumstances expected future short rates are equal to the actual short rate and variations of the spread are only brought about by changes in the risk premium in this note the short term interest rate stabilization explanation for the failure of the predictive implications of the expectations theory of the term structure is subjected to an additional empirical test using recent monthly data thereby the short end of the term structure of swiss german and u s interest rates is analyzed for the years 1974 1986 these three cases are of great interest in our context the swiss national bank and the german federal bank used the opportunity offered by the flexible exchange rate system to implement money supply targets and did not attempt to stabilize short term interest rates whereas the federal reserve was at

options on the maximum or the minimum of several assets using an intuitive approach that also provides new intuition concerning the black and scholes equation this paper extends the results of johnson and stulz to the pricing of options on the minimum or the maximum of several risky assets

a synthetic option framework for asset allocation what if investors could buy a call option that would grant them the right to purchase at the end of a performance measurement period a full position in the better performing of either stocks or bonds the appropriate investment strategy in that case wotuld be to invest in a riskless asset that portion of total funds sufficient to achieve a desired mninimum return over the period and to use the remaining funds to purchase the multiple risky asset call options although such options are not available in the marketplace their return pattern can be replicated by a trading strategy utilizing stocks bonds and cash this involves taking positions in each risky asset and financing the positions by borrowing in the riskless asset the investor takes larger positions in the risky assets as the assets perform well along with a larger borrowing position and smaller positions in the risky assets as they perform poorly along with smaller borrowing positions historical simulations of the synthetic option asset allocation approach achieved good results in both bull and bear markets over the 1973 83 period the compound perfornmance over the most recent three five and 10 year holding periods ending in 1983 was not only first quartile but first decile for the 10 year period and close to first decile for the other periods

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

the effects of market segmentation and investor recognition on asset prices evidence from foreign stocks listing in the united states non u s firms cross listing shares on u s exchanges as american depositary receipts earn cumulative abnormal returns of 19 percent during the year before listing and an additional 1 20 percent during the listing week but incur a loss of 14 percent during the year following listing we show how these unusual share price changes are robust to changing market risk exposures and are related to an expansion of the shareholder base and to the amount of capital raised at the time of listing our tests provide support for the market segmentation hypothesis and merton s 1987 investor recognition hypothesis the globalization of u s capital markets has accelerated dramatically in the past decade increasing numbers of companies from overseas have chosen to either raise capital through global equity issues or prepare for future capital raising by way of cross listings on u s exchanges as of 1997 about 1 300 non u s companies have listed their shares for trading on the new york stock exchange nyse the american exchange amex the national association of securities dealers automation quotation nasdaq system or

does the bonding effect matter in a more integrated capital market world abstract this paper examines the bonding effect of cross listing before and after the stock market liberalization reforms in china consistent with the bonding hypothesis we find that chinese firms with foreign listings attain higher valuations than firms without foreign listings we also find that they manage earnings less than comparable purely domestic listed firms and have more informative stock prices further investigation indicates that the divergence in earnings quality between cross listed and non cross listed firms shrinks dramatically after the chinese stock market liberalization reforms in 2001 and 2002 overall the results suggest that the bonding effect is mitigated in an increasingly integrated capital market world

differential interpretations and trading volume this study provides evidence that differential interpretations are an important stimulus for speculative trading we measure differential interpretations using data on analysts revisions of forecasts of annual earnings after the announcement of quarterly earnings that are components of those annual earnings numbers we find two conditions under which differential interpretations play a significant role in explaining trading first we present empirical evidence supporting kandel and pearson s 1995 argument that trading coincident with small price changes reflects investors differential interpretations of information this evidence is important because it is inconsistent with conventional models of trade that assume homogeneous interpretations second we also find that differential interpre tations explain a significant amount of the trading occurring in a sample where trading volume is higher than the firm specific non announcement period average this result is consistent with informed traders acting on their differential interpretations when there is enough liquidity trading to help camouflage their own information based trades in sum the study s results confirm bachelier s 1900 intuition that differential interpretations are an important stimulus for trading

an analysis of the wealth effects of japanese offshore dollar denominated convertible and warrant bond issues offshore dollar denominated equity linked issues were a more important source of funds for japanese companies during the 1980s than domestic equity and straight debt issues combined using a sample of japanese equity linked offshore issues from 1977 to 1989 we find that the announcement of these issues is accompanied by a significant positive abnormal return this contrasts with evidence that u s equity linked issues have a significant negative stock price reaction we provide an explanation for the difference in stock price reactions between u s and japanese issues that is based on the greater influence on managers security issue decisions of long term investors and banks in japan than in the u s

capital raising in the offshore market abstract us corporations can raise capital in the offshore market using regulation s adopted by the securities and exchange commission sec in 1990 and modified in 1996 we examine how offshore offerings are done under regulation s what types of companies use this market the discount companies offer investors to compensate for illiquidity in the market and the impact of the new disclosure requirements on capital raising in the offshore market we find that small firms tend to raise capital in this market during our sample period before the 1996 rule change the median market capitalization of reporting firms was 16 82 million with a median stock price of 1 13 the mean and median discount offered to foreign investors was 32 84 and 40 53 respectively offerings during this period resulted in average share dilution of 11 97 we find that before the disclosure requirements firms were gaming the system by giving foreign investors just enough time to resell the securities back into the united states before the initial sale became public information after the rule changes regulation s offerings are not perceived to be shady and larger firms are now using the market resulting in lower average discount and dilution
