minimum effort coordination games stochastic potential and logit equilibrium abstract this paper revisits the minimum effort coordination game with a continuum of pareto ranked nash equilibria noise is introduced via a logit probabilistic choice function the resulting logit equilibrium distribution of decisions is unique and maximizes a stochastic potential function in the limit as the noise vanishes the distribution converges to an outcome that is analogous to the risk dominant outcome for 2 2 games in accordance with experimental evidence logit equilibrium efforts decrease with increases in effort costs and the number of players even though these parameters do not affect the nash equilibria journal of economic literature classification numbers c72 c92

the term structure of euromarket interest rates an empirical investigation abstract this paper is an empirical investigation of the predictability and co movement of risk premia in the term structure of euromarket interest rates we present regression results which suggest that risk premia in three euromarket term structures and on uncovered foreign asset positions move together we test formally the hypothesis that these risk premia move in proportion to a single latent variable we are unable to reject this hypothesis the single latent variable model can be interpreted as in hansen and hodrick 1983 and hodrick and srivastava 1984 as a specialization of the icapm in which assets have constant betas on a single unobservable benchmark portfolio

intraday technical trading in the foreign exchange market this paper examines the out of sample performance of intraday technical trading strategies selected using two methodologies a genetic program and an optimized linear forecasting model when realistic transaction costs and trading hours are taken into account we find no evidence of excess returns to the trading rules derived with either methodology thus our results are consistent with market efficiency we do however find that the trading rules discover some remarkably stable patterns in the data

answering the skeptics yes standard volatility models do provide accurate forecasts a voluminous literature has emerged for modeling the temporal dependencies in financial market volatility using arch and stochastic volatility models while most of these studies have documented highly significant in sample parameter estimates and pronounced intertemporal volatility persistence traditional ex post forecast evaluation criteria suggest that the models provide seemingly poor volatility forecasts contrary to this contention we show that volatility models produce strikingly accurate interdaily forecasts for the latent volatility factor that would be of interest in most financial applications new methods for improved ex post interdaily volatility measurements based on high frequency intradaily data are also discussed

the information content of security prices a second look abstract beaver lambert and morse 1980 employ a regression of percentage change in prices on percentage change in earnings in which data are grouped by the dependent variable reverse regression offers a more intuitive and direct way to assess the information content of security prices the objective of beaver et al while grouping is asymptotically equivalent reverse regression is a more efficient way of examining the incremental explanatory power of lagged values of percentage change in price with respect to accounting earnings

information in prices about future earnings abstract stock return over a period reflects the market s revision in expectation of future earnings accounting earnings over the same period however have limited ability to reflect such revised expectations therefore returns anticipate earnings changes and the earnings response coefficient from a regression of returns on contemporaneous earnings changes is biased toward zero we reduce this bias by including leading period returns in price earnings regressions the resulting estimated earnings response coefficient magnitudes suggest that the capital market on average views earnings changes to be largely permanent this is consistent with the random walk time series property of annual earnings

boundedly rational nash equilibrium a probabilistic choice approach we propose an equilibrium for n person finite games based on bounded rationality using the legit model of discrete choice theory at equilibrium each player uses appropriate choice probabilities given those used by the others rationality is parameterized on a continuum from complete rationality to uniform random choice results on the existence of equilibrium and on convergence to nash as rationality becomes perfect are similar to results due to mckelvey and palfrey we identify conditions such that for a given rationality parameter range the path of choices over time when the players use fictitious play converges to equilibrium c 1997 academic press

a theoretical analysis of altruism and decision error in public goods games abstract we formalize an equilibrium model in which altruism and decision error parameters determine the distribution of contributions for linear and quadratic public goods games the equilibrium density is exponential for linear games and normal for quadratic games our model implies i contributions increase with the marginal value of the public good ii total contributions increase with the number of participants iii mean contributions lie between the nash prediction and half the endowment these predictions which are not implied by a nash analysis are consistent with laboratory data maximum likelihood estimates of altruism and error parameters are significant and plausible

on the term structure of the foreign exchange rates and market efficiency abstract the efficiency hypothesis of the foreign exchange market is examined by considering the term structure of foreign exchange rates jointly with that of interest rates in the context of interest rate parity principle the canadian u s data are found to be consistent with the hypothesis of the market efficiency and a constant exchange risk premium

rent seeking with bounded rationality an analysis of the all pay auction the winner take all nature of all pay auctions makes the outcome sensitive to decision errors which we introduce with a logit formulation the equilibrium bid distribution is a fixed point the belief distributions that determine expected payoffs equal the choice distributions determined by expected payoffs we prove existence uniqueness and symmetry properties in contrast to the nash equilibrium the comparative statics of the logit equilibrium are intuitive rent dissipation increases with the number of players and the bid cost overdissipation of rents is impossible under full rationality but is observed in laboratory experiments our model predicts this property

price competition when three are few and four are many abstract i examine price competition in a market for a homogeneous good when consumers observe prices subject to a random shock perception error when firms have symmetric costs there exists a unique equilibrium in pure strategies which is symmetric when there are up to three sellers in the market the sellers extract the entire consumer surplus however with at least four firms assuming that the marginal cost is sufficiently low relative to consumers valuation both consumers and producers may enjoy a positive surplus the marginal cost pricing is never observed in an equilibrium with finitely many firms potential policy implications are discussed

modelling the efficiency of the canadian foreign exchange market a bivariate transfer function analysis the efficient market hypothesis for the canadian foreign exchange market is tested using monthly data on spot and forward exchange rates from january 1973 to october 1995 unlike most previous studies we have estimated a transfer function model which combines the results of the univariate time series models with those of the regression model following the convention equations derived from the market efficiency models have been used in both level and change specifications like many previous studies the results from the transfer function model have failed to provide evidence in support of the efficient market hypothesis these findings suggest that significant arbitraging opportunities existed in the canadian foreign during the period under study

repeated games and limited forecasting abstract this paper considers two player repeated games with discounting each player is assumed to form a prediction over a limited horizon while his view about what will come next is only vague following jehiel 1995 journal of economic theory 67 497 519 a solution concept is proposed in which the players make correct predictions over their horizon of forecast and the vagueness about what will come next is modelled as a source of randomness in players criteria applications to the repeated prisoner s dilemma are reported suggesting that in contrast to received theory it may be easier to sustain cooperation when the players are not too patient and it may be easier to sustain cooperation than non cooperation

another look at the role of the industrial structure of markets for international diversification strategies abstract this paper re examines the extent to which gains from international diversification are due to differences in industrial structure across countries recent papers by roll 1992 journal of finance 47 3 42 and heston and rouwenhorst 1994 journal of financial economics 36 3 27 investigate this issue and find conflicting evidence using a new database the dow jones world stock index with coverage in 25 countries and over 66 industry classifications we decompose comprehensively both country and industrial sources of variation we confirm that little of the variation in country index returns can be explained by their industrial composition we also uncover differences in the proportion of variation in industry index returns that is captured by country and industry factors and discuss the implications for global diversification strategies

the principle of minimum differentiation holds under sufficient heterogeneity the so called principle of minimum differentiation stated by hotelling has been challenged by many authors this paper restores the principle by showing that n firms locate at the center of the market and charge prices higher than the marginal cost of production when heterogeneity in consumers tastes is large enough

a quantal response equilibrium model of order statistic games abstract this paper applies mckelvey and palfrey s games econ behav 10 1995 6 notion of quantal response equilibrium to a class of order statistic coordination games closely related to those studied by van huyck et al am econ rev 80 1990 234 quart j econ 106 1991 885 and van huyck et al evidence on learning in coordination games manuscript texas a m university 1996 and those recently analyzed by anderson et al games econ behav 34 2001 177 with quadratic effort costs the limiting qre as the noise goes to zero in their games is the most efficient equilibrium this result contrasts with anderson et al s conclusion for order statistic games with linear effort costs and allows a fuller assessment of the qre s success in describing the limiting outcomes in van huyck et al s experiments

covered interest arbitrage and market turbulence the covered interest parity theorem states that the covered interest differential between two similar assets denominated in different currencies should be zero this paper utilizes high quality data recorded by the dealers at the bank of england to test covered interest parity during certain historical periods in which there is known to have been turbulence as well as during a relatively calm control period the data is high frequency and allowance is made for the bid offer spread brokerage costs and other considerations the results have three main implications firstly profitable arbitrage opportunities do occasionally occur and sometimes persist during turbulent periods secondly the degree of efficiency of the relevant markets appears to have increased over time thirdly there appears to be a maturity effect whereby the existence and size of profitable arbitrage opportunities appear to be positive functions of the length of maturity a rationalization of this phenomenon is offered in terms of the existence of credit limits copyright 1989 by royal economic society

strategic interaction and the statistical analysis of international conflict although strategic interaction is at the heart of most international relations theory it has largely been missing from much empirical analysis in the field typical applications of logit and probit to theories of international conflict generally do not capture the structure of the strategic interdependence implied by those theories i demonstrate how to derive statistical discrete choice models of international conflict that directly incorporate the theorized strategic interaction i show this for a simple crisis interaction model and then use monte carlo analysis to show that logit provides estimates with incorrect substantive interpretations as well as fitted values that can be far from the true values finally i reanalyze a well known game theoretic model of war bueno de mesquita and lalman s 1992 international interaction game my results indicate that there is at best modest empirical support for their model

the information content of earnings and prices a simultaneous equations approach abstract the price earnings relation can be characterized as a system of simultaneous equations earnings and prices can behave as if they are both endogenously determined because they are jointly affected by information that is difficult to specify explicitly specification tests provide evidence that both earnings changes and price changes are endogenous the price and earnings coefficients increase from ols to joint estimation and under a restrictive set of assumptions provide increasingly similar estimates of the permanent component of earnings the evidence is consistent with the contention that a portion of the single equation bias can be mitigated via joint estimation

the logit equilibrium a perspective on intuitive behavioural anomalies costs associated with deviations from the nash equilibrium these payoff asymmetry effects are incorporated in an approach that introduces noisy behavior via a logit probabilistic choice function in the resulting logit equilibrium behavior is characterized by a probability distribution that satisfies a rational expectations consistency condition the beliefs that determine players expected payoffs match the decision distributions that arise from applying the logit rule to those expected payoffs we prove existence of a unique symmetric logit equilibrium and derive comparative statics results the paper provides a unified perspective on many recent laboratory studies of games in which nash equilibrium predictions are inconsistent with both intuition and experimental evidence

market assessment of industry and firm earnings information abstract this study examines the timing of security returns associated with industry wide earnings and firm specific earnings we predict and find that returns associated with differences in performance across industries begin and end earlier than returns associated with differences in firm specific performance within industries to earn abnormal profits a trading strategy based on forecasts of future earnings would require earlier predictions of industry wide earnings than of firm specific earnings

rational expectations risk and efficiency in the london metal exchange an empirical analysis there now exists a number of studies which reject efficiency of the london metal exchange as a joint null hypothesis of rational expectations and risk neutrality in this paper we investigate the presence of time varying risk premia in a number of metal price series conditional on the assumption of rationality our findings include evidence to suggest that forward prices contain information on future spot prices over and above the information contained in current spot prices that there is some evidence of time varying premia in the forward prices for tin and zinc and that the behaviour of these premia are intuitively plausible in particular there appears to be significant covariation between risk premia and the expected spot price change

estimating earnings response coefficients pooled versus firm specific models abstract short window earnings response coefficients estimated from pooled time series cross sectional regressions are systematically smaller than corresponding averages of firm specific coefficients estimated from time series regressions the cause is a negative relation between firm specific earnings response coefficients and unexpected earnings variances if the hypotheses of equality of firm specific coefficients and equality of firm specific unexpected earnings variances are rejected firm specific estimation should be used instead of pooled estimation using pooled estimation may lead to incorrect inferences about the magnitude of estimated coefficients and or incorrect inferences about differences in coefficient behavior between groups of firms

permanent versus transitory components of annual earnings and estimation error in earnings response coefficients abstract previous research has generally estimated unexpected earnings as the change relative to the previous year assuming that shocks to annual earnings are purely permanent in the presence of transitory components of annual earnings we predict that using earnings changes as a proxy for unexpected earnings causes earnings response coefficients to be understated and the estimation error to be negatively cross sectionally correlated with persistence the negative correlation causes the association between earnings response coefficients and persistence to be overstated we use the ima 1 1 model to capture transitory components of annual earnings and obtain results that are consistent with our predictions

urban commuters mode switching behaviour in taipai with an application of the bounded rationality principle this paper applies the bounded rationality rule to analyse commuters mode switching behaviour from private transport i e automobile and motorbike to public transport i e rail transit and bus transit in the taipei metropolitan area a stated choice approach was used to collect the data and to investigate how different attributes such as parking fees travel time and cost influence commuters mode switching behaviour a multinomial probit modelling framework was developed to capture the correlation effects when commuters switch from private to public modes the estimation results indicate that the socioeconomic characteristics and trip characteristics significantly influence commuters mode switching behaviour accounting for the structure of unobserved effects suggests that switching behaviour from private to public modes was significantly positively correlated an elasticity analysis shows that private commuters were more likely to switch to mrt than to bus and that auto commuters are generally m

binary games with state dependent stochastic choice this paper studies a stochastic equilibrium selection model for binary coordination games players switch strategies stochastically so that the mistake probabilities are fully dependent on the population states a probabilistic behavior is said to be aspiration imitation resp oriented if strategy switches are mainly driven by the aspiration imitation resp effect in general a strategy switch by one player generates externalities on others strategies in a coordination game can be classified according to the relative magnitude of their externality effects it is shown that the selection outcome for a linear coordination game is determined in a specific way by the balance of the risk dominance the aspiration imitation and the externality effects it is also shown that an aspiration imitation resp oriented behavior tends to select payoff dominant maxmin resp equilibrium and that risk dominant equilibrium is always selected if and only if the aspiration and the imitation effects exactly cancel each other out which in turn makes the selection process insensitive to externality effects journal of economic literature classification number c72

corporate capital expenditure decisions and the market value of the firm abstract this paper is an event time study of the common stock prices of a sample of 658 corporations around the dates on which they publicly announced their future capital expenditure plans for industrial firms announcements of increases decreases in planned capital expenditures are associated with significant positive negative excess stock returns for public utility firm neither increases nor decreases in planned capital expenditures are associated with significant excess stock returns we interpret the evidence as being consistent with the hypothesis that managers seek to maximize the market value of the firm in making their corporate capital expenditure decisions

on some international parity conditions an empirical investigation abstract this paper investigates weak semi strong and strong forms of the following international parity conditions a uncovered interest parity b the hypothesis of equal ex ante real interest rates and c ex ante purchasing power parity the main results are as follows using data which roughly cover the 1975 1984 decade we find little evidence in favor of the strong form of the parity conditions under consideration however most test results are consistent with the weak forms finally regarding the semi strong forms the results are mixed

noisy directional learning and the logit equilibrium we specify a dynamic model in which agents adjust their decisions toward higher payoffs subject to normal error this process generates a probability distribution of players decisions that evolves over time according to the fokker planck equation the dynamic process is stable for all potential games a class of payoff structures that includes several widely studied games in equilibrium the distributions that determine expected payoffs correspond to the distributions that arise from the logit function applied to those expected payoffs this logit equilibrium forms a stochastic generalization of the nash equilibrium and provides a possible explanation of anomalous laboratory data

real investment implications of employee stock option exercises this paper examines a real cost of awarding employee stock options based on the observation that managers are extremely concerned about earnings per share dilution in equity related compensation we predict and find that firms experiencing significant employee stock option eso exercises shift resources away from real investments towards the repurchase of their own stocks we further find weak evidence of a decline in subsequent firm performance as measured by return on assets for several years following the cut in discretionary investments as a result of stock option exercises though this result is sensitive to the metric used to measure performance collectively our findings indicate that eso exercises potentially impose a real cost on the firm in terms of foregone investment opportunities

the association between accounting earnings and security returns for large and small firms abstract the differential information hypothesis advanced by atiase 1980 states that information production and dissemination by private parties for the purpose of identifying mispriced securities is an increasing function of firm size this study examines two corollaries of that hypothesis first security prices of large firms anticipate accounting earnings earlier than security prices of small firms second for a given level of unexpected earnings the cumulative abnormal returns of small firms exceed those of large firms the results are generally consistent with atiase s hypothesis

the valuation of the foreign income of us multinational firms a growth opportunities perspective we demonstrate the value relevance of foreign earnings for us multinational firms by examining the associations between annual abnormal stock performance and changes in firms domestic and foreign incomes for 2570 tirm year observations between 1985 and 1993 both foreign and domestic earnings changes have significant positive associations with annual excess return measures however the association coefficient on foreign income is significantly larger than the association coefficient on domestic income we demonstrate this larger association coefficient for foreign income is consistent with differences in growth opportunities between domestic and foreign operations

testing interest rate parity and rational expectations for canada and the united states the purpose of this paper is to examine the joint hypothesis of interest rate parity and rational expectations for canada and the united states using monthly data two approaches to testing are considered 1 the substitution method and 2 testing the cross equation non linear rational expectations restrictions from solving the interest rate parity equation it is demonstrated that standard application of the substitution method requires the assumption that the interest rate parity equation holds deterministically tests for unit roots in the spot exchange rate and interest rate differentials are also investigated

discrete choice and variable returns to scale in previous studies of the probabilistic theory of qualitative choice e g marschak 1960 and mcfadden 1974 it has been assumed that an individual chooses among various alternatives with their utility levels independent of the number of individuals who choose each alternative there are however many examples in which the utility of a choice depends on the number of individuals who make the same choice for instance the utility of a given spatial choice may depend upon the number of others who choose neighboring locations neighborhood utility may decrease crowding or it may increase agglomerative economies with population size a second example is the automobile traveler s choice of routes the benefit of one route choice over another due to congestion depends on the number of drivers who choose the same route both of the examples suggested above deal with spatial choices of a particular kind but there are even examples from the more traditional macroeconomic theory one such example is of a product produced under variable returns to scale by a number of different sellers the price that each seller charges will depend upon the number of his customers if a buyer must choose to purchase from only one seller the price paid and thus utility will depend upon the total number of buyers choosing the same seller in all of the examples cited a reasonable model of choice is one that postulates uncertainty about the actual utility of each alternative the point of view is that a chooser s notional utility about each choice is a random variable in this case it is not certain which alternative will be chosen but the chosen alternative is the one with the greatest perceived utility it follows therefore that the probability that a given alternative is chosen is the probability that the utility perceived to be associated with it is larger than the utility perceived to be associated with any other alternative

internal corporate restructuring abstract firms that alter their divisional configurations on average increase shareholder wealth gains appear to come from information about investment opportunities and increases in efficiency performance before the restructurings suggests poorly organized firms are motivated by market pressures to change their organizations change also occurs in healthy firms as part of the growth process restructuring often occurs where there is no evidence of takeover threats while stock prices increase around the restructurings there is a contemporaneous decline in earnings due to increased expenses these findings appear inconsistent with the contention that the market pressures managers into focusing on short run earnings

earnings as an explanatory variable for returns in this paper we investigate whether the level of earnings divided by price at the beginning of the stock return period is relevant for evaluating earnings returns associations the primary model motivating this research relies on the idea that book value owners equity and market value are both stock variables indicating the wealth of the firm s equity holders the related flow variables after adjusting for dividends are respectively earnings divided by price at the beginning of the return period a p 1 and market returns it then follows that earnings divided by beginning of period price should be associated with stock returns although models based on a relation between market value and book value are used occasionally in the accounting research literature see for example landsman 1986 harris and ohlson 1987 and barth

the relation between the return interval and betas abstract the size effect is sensitive to the length of the return interval used in estimating betas beta changes with the return interval because an asset s covariance with the market and the market s variance do not change proportionately as the return interval is changed we document beta sensitivity to the return interval evidence from cross sectional regressions of returns on monthly and annual betas is inconsistent with beta changes stemming only from the higher standard errors of the longer interval betas we provide evidence that the size effect becomes statistically insignificant when risk is measured by betas estimated using annual returns

expectations of exchange rates and differential inflation rates further evidence on purchasing power parity in efficient markets the paper tests the null hypothesis of ex ante purchasing power parity the empirical evidence obtained is inconsistent with the null for major industrialized countries over the current floating exchange rate regime expected nominal exchange rate changes appear to deviate systematically from expected inflation rate differentials over the same holding period even though real exchange rate changes appear to be serially uncorrelated this supports the presence of time varying risk premia in foreign exchange markets and real determinants of exchange rate movements as suggested by equilibrium theories of international asset markets this paper tests the hypothesis that the expected change in the exchange rate of two countries equals the expected differential in their inflation rates over the same holding period this relationship is an ex ante version of the classical relative purchasing power parity ppp that holds under some versions of efficient foreign exchange and international commodity markets it has important implications for the efficacy of government policies in open economies and has been the focus of numerous empirical studies the ex ante ppp eppp differs from the traditional ppp proposed by cassel 4 in the explicit treatment of uncertainty as formulated by roll 32 the eppp is based on the constraint that in efficient markets the net return to speculators engaging in intertemporal speculation on goods in the foreign country is anticipated to be zero 1 an immediate implication of eppp is that innovations in real exchange rates or deviations from ppp follow a martingale process in sharp contrast to the well documented empirical rejections of the conventional ppp strong support for the martingale property of eppp exists in the literature 2 the proposition that the differences in the expected price relatives of two countries are exactly accounted for by the expected change in exchange rates over the same period is inconsistent with a number of theoretical observations in the extant literature in particular the eppp model assumes that the expected real interest rate differential between each pair of countries is intertemporally constant in order to rule out commodity and financial arbitrage in a world of

firm size and the information content of prices with respect to earnings abstract beaver lambert and morse 1980 suggest that prices may be useful in forecasting future earnings we explore the information content of prices with respect to earnings by focusing on firm size and its relation to the predictive accuracy of price based earnings forecasts firm size proxies for the amount of information and for the number of traders and professional analysts processing the available information about an enterprise our empirical results are consistent with the hypothesis that price based earnings will outperform univariate time series forecasts by a greater margin for larger firms than for smaller firms

fair value disclosures by bank holding companies abstract this paper examines the value relevance of fair value data disclosed under sfas 107 by banks for 1992 and 1993 collectively the evidence suggests differences between fair and book values of financial instruments are associated with market to book ratios however fair value disclosures for financial instruments other than securities are value relevant only in limited settings in addition only in 1992 are fair value variables associated with market to book ratios after incorporating existing historical cost information further analysis suggests the weaker 1993 results are not necessarily due to increased measurement error in fair value numbers

limited foresight may force cooperation this paper considers discounted repeated games with boundedly rational players in each period player i chooses his current action on the basis of his forecast about the forthcoming n i action profiles his assessment of the payoffs he will obtain next depends on his state of mind which is non deterministic a limited forecast equilibrium is such that after every history the limited horizon forecasts formed by the players are correct the set of all limited forecast equilibria is characterized and constructed application to the repeated prisoner s dilemma shows that limited foresight may sometimes induce purely cooperative paths while purely non cooperative paths cannot arise

tests of rational expectations and no risk premium in forward exchange markets abstract this paper tests the simple efficiency hypothesis i e that traders have rational expectations and charge no risk premium in the forward exchange market it uses a statistical procedure which is consistent under a large class of heteroscedasticity and a set of data which takes into account the institutional features of the forward exchange market the results show that this procedure leads to stronger rejections of the simple efficiency hypothesis than do procedures using the standard assumption of homoscedasticity

trading rule profits in european currency spot cross rates abstract the moving average ma trading rule is applied to six european spot cross rates jy bp dm bp jy dm sf dm sf bp and jy sf to see if opportunities for profitable trading exist the results suggest that ma trading rules are marginally profitable only for the jy dm and the jy sf cross rates while trading rules are not profitable for the other four cross rates bootstrapping and out of sample tests provide similar results examination of subsamples characterized by central bank intervention do not produce different results computation of box pierce statistics adjusted for heteroscedasticity show that daily returns for all six cross rates are serially uncorrelated overall the results suggests that cross rates are sufficiently transparent to eliminate ma trading rule profit

do baths muddy the waters or clear the air we examine the information environments of firms following large non recurring charges baths we test competing hypotheses about the consequences of a bath a bath either improves the information environment the transparency hypothesis or degrades it the opacity hypothesis difference in differences analysis suggests that after a bath 1 earnings become smoother 2 firm level information asymmetry decreases and 3 stock returns become more responsive to unexpected earnings we interpret these findings as supportive of the transparency hypothesis we also document that the relative improvement in the information environment is greater for baths that are not voluntary consistent with managerial obfuscation prior to the bath

the term structure of the forward premium abstract most studies of the efficiency of the foreign exchange market focus on a single maturity usually a one month forward exchange rate however one observes that forward contracts of many maturities are simultaneously traded in the foreign exchange market the hypothesis that the foreign exchange market uses all available information has implications for the joint behavior of forward exchange rates of various maturities this paper proposes an equilibrium theory of the term structure of the forward premium the model is tested using data on the german and canadian exchange rates the results indicate that the data are consistent with the theory for germany and inconsistent with the theory for canada

can we sterilize theory and evidence under managed floating as under the bretton woods system central banks have intervened heavily in the foreign exchange market as before they have often attempted to divorce their intervention activities from their money supplies through offsetting operations in domestic financial markets an official purchase of foreign exchange can be sterilized through a corresponding openmarket sale of domestic securities the transaction which is equivalent to an official forward sale of domestic currency leaves relative money supplies unchanged but alters the relative supplies of foreign and domestic currency bonds available to the public regardless of the exchange rate regime sterilized intervention may be viewed as an attempt to attain independent exchange rate and money stock targets in the short run for this to be possible bonds denominated in different currencies must be imperfect substitutes in private portfolios if feasible sterilization may or may not be useful in attaining the long run objectives of the central bank

modeling bounded rationality in capacity allocation games with the quantal response equilibrium we consider a supply chain with a single supplier and two retailers the retailers choose their orders strategically and if their orders exceed the supplier s capacity quantities are allocated proportionally to the orders we experimentally study the capacity allocation game using subjects motivated by financial incentives we find that the nash equilibrium which assumes that players are perfectly rational substantially exaggerates retailers tendency to strategically order more than they need we propose a model of bounded rationality based on the quantal response equilibrium in which players are not perfect optimizers and they face uncertainty in their opponents actions we structurally estimate model parameters using the maximum likelihood method our results confirm that retailers exhibit bounded rationality become more rational through repeated game play but may not converge to perfect rationality as assumed by the nash equilibrium finally we consider several alternative behavioral theories and show that they do not explain our experimental data as well as our bounded rationality model this paper was accepted by loana popescu guest editor operations management

central bank intervention and trading rule profits in foreign exchange markets abstract moving average trading rules are utilized in both futures and spot foreign currency markets to show that significant positive profits can be earned in four of five currencies examined the results are consistent for both in sample and forward simulation tests regression results demonstrate that central bank intervention is strongly associated with the profitability of trading returns for the three major currencies dm yen and pound and partially explains returns for the sf and cd consistent with conjectures in previous studies that news concerning intervention tends to be revealed over weekends we find that moving average trading rule returns are significantly positive on fridays and mondays and not significantly different from zero in the middle of the week

earnings management to avoid earnings decreases and losses this paper provides evidence that firms manage reported earnings to avoid earnings decreases and losses specifically in cross sectional distributions of earnings changes and earnings we lind unusually low frequencies of small decreases in earnings and small losscs and unusually high frequencies of small increases in earnings and small positive income we find evidence that two components of earnings cash flow from operations and changes in working capital are used to achieve increases in earnings we present two theories based on stakeholder use of information processing heuristics and prospect theory about the motivation for avoidance of earnings decreases and losses

an experimental study of jury decision rules we present experimental results on groups facing a decision problem analogous to that faced by a jury we consider three treatment variables group size three or six number of votes needed for conviction majority or unanimity and pre vote deliberation we find evidence of strategic voting under the unanimity rule a large fraction of our subjects vote for a decision analogous to conviction even when their private information indicates a state analogous to innocence this is roughly consistent with the game theoretic predictions of feddersen and pesendorfer although individual behavior is explained well by the game theoretic model there are discrepancies at the level of the group decision contrary to feddersen and pesendorfer in our experiments there are fewer outcomes analogous to incorrect convictions under unanimity rule than under majority rule in the case of no deliberation we simultaneously account for the individual and group data using quantal response equilibrium

cross sectional dependence and problems in inference in market based accounting research this paper provides a framework and some empirical evidence to evaluate the seriousness of problems in inference that arise in stockreturn based studies when the data are cross sectionally dependent the study is motivated on the grounds that statistical procedures designed to address such problems are often infeasible and even when they can be implemented they sometimes introduce other more serious difficulties thus researchers have frequently adopted an approach that ignores the cross sectional dependence e g ordinary least squares ols the objective of this paper is to help identify the contexts in which ignoring the dependence would lead to serious misstatement of significance levels cross sectional dependence in stock returns data is likely to exist when at least some of the returns are sampled from common time periods this would be the case in all studies of the reaction of stock prices to a

asymmetric stationarity in national stock market indices an mtar analysis a procedure is developed using a momentum threshold autoregressive model and asymmetric stationarity tests designed to identify periods of asymmetric stationary divergences from nonstationary paths in time series and is applied to major national stock indices the results reveal the existence of asymmetric stationary periods in each of these indices these results suggest an explanation for the counterintuitive positive forecasting results of technical traders for various time periods we explore this possibility further by using a representative moving average technical trading strategy and find significantly different results higher returns when information from the procedure is incorporated into a trading rule

accounting earnings and top executive compensation abstract this paper investigates the role of accounting earnings in top executive compensation contracts it provides evidence in support of the hypothesis that earnings based incentives help shield executives from market wide factors in stock prices the paper demonstrates that earnings reflect firm specific changes in value but are less sensitive to market wide movements in equity values as a result the inclusion of earnings based performance measures in executive compensation contracts helps shield executives from fluctuations in firm value that are beyond their control the hypothesis is shown to explain cross sectional variation in the use of earnings based incentives

efficiency in foreign exchange markets a vector autoregression approach abstract this paper examines and tests the simple efficiency property of the forward exchange market by analyzing the linearly indeterministic covariance stationary propertoes of the vector stochastic proceess that governs the joint behavior of the spot exchange rate and forward rates wiht different maturity dates a multivariate autoregressive methodology for testing the simple efficiency hypothesis that relies upon a set of highly non linear cross equation restrictions is utilized the results of the estimation and testing for the british pound and the deutsche mark over the period september 1974 to november 1987 using monthly observation on the spot rate the one month forward rate and the three month forward rates are presented special concern is given to the sensitivity of the tests results to subsampling over the period

the fall of enron the financial reporting and disclosure problems at enron as well as the high market valuations for its stock raise troubling questions about the functioning of capital market intermediaries regulators and governance experts whose are supposed to ensure the effective functioning of the stock market this paper examines the functions of key capital market intermediaries and analyzes how their own governance and incentive problems may have contributed to enron s rise and fall we conclude by proposing system modifications to resolve the observed problems

association between accounting performance measures and stock prices a test of the life cycle hypothesis abstract this paper posits that stock market response to two accounting performance measures sales growth and capital investment is a function of firm life cycle stage firms are grouped into various life cycle portfolios using dividend payout sales growth and age as predicted the empirical results indicate a monotonic decline in the response coefficients of unexpected sales growth and unexpected capital investment from the growth to the stagnant stages additional analysis suggests that this relation is not driven by a firm size effect risk differences or measurement error in the proxies for performance measures

on the empirical content of quantal response equilibrium the quantal response equilibrium qre notion of mckelvey and palfrey 1995 has recently attracted considerable attention due largely to its widely documented ability to rationalize observed behavior in games played by experimental subjects we show that this ability to t the data as typically measured in this literature is uninformative without ap riori distributional assumptions a qre can match any distribution of behavior by each player in any normal form game we discuss approaches that might be taken to provide valid empirical evaluation of the qre and discuss its potential value as an approximating empirical structure

quantal response equilibrium models of the ultimatum bargaining game abstract this paper investigates the implications of quantal response equilibrium qre models mckelvey and palfrey 1995 games econ behav 10 6 38 1998 exper econ 1 9 41 in the ultimatum bargaining game it is shown that in a normal form qre nqre each bargainer s decision depends critically on the anticipated behavior of the other and there is a nqre in which the proposer makes any offer between zero and equal split as a strict best response the application of nqre to the experimental data slonim and roth 1998 econometrica 66 569 596 suggests that the history dependence observed in the experiment is a result of the strategic interactions between bargainers

the effect of accounting procedure changes on ceos cash salary and bonus compensation abstract this paper examines the effect of accounting procedure changes on cash salary and bonus compensation to ceos we estimate whether there is an adjustment to the statistical relation between compensation and corporate earnings following changes that lower earnings fifo to lifo inventory valuation and that raise earnings accelerated to straight line depreciation the results indicate that 1 subsequent to these changes salary and bonus payments are based on reported earnings rather than earnings under the original accounting method and 2 the potential compensation effect of the changes is small compared to the effect of economy or industry wide changes in compensation

probabilistic choice and procedurally bounded rationality abstract we derive a family of probabilistic choice models including the multinomial logit model from a microeconomic model in which the decision maker has to make some effort in order to implement any desired outcome the disutility of this effort enters the decision maker s goal function in an additively separable way a particular disutility function yielding the multinomial logit as a special case is characterized axiomatically the present approach naturally leads to a normalization of the achieved utility with respect to the number of alternatives the approach also applies to continuum choice sets in euclidean spaces and provides a microeconomic foundation for logit type quantal response models in game theory

strategic customer behavior facing possible stockout an experimental study abstract this paper studies strategic customer behavior in a monopolistic seller system given the stock quantity and the selling prices a customer chooses either to buy at the full price to certainly obtain a product or to wait for a discount with the risk of stockout we model the behavior of strategic customers as a customer game it is shown that the customer game may have multiple nash equilibria specifically in the condition of weak incentive compatibility the trembling hand perfect equilibrium is all wait which is inconsistent with the all buy assumption in the literature we conduct laboratory experiments to investigate behavior of strategic customers the results show that customers behaviors exhibit a deviation from nash equilibria using a framework of quantal response equilibrium we develop behavioral models to effectively characterize the behavior of strategic customers

modelling cognitively bounded rationality an evaluative taxonomy abstract since its origins in the 1950s the notion of bounded rationality has been incorporated into economic theory using an array of methodological approaches this paper presents a taxonomy by which these approaches can be categorized and understood evaluating each approach against a range of important criteria at a time when the foundations of economic theory are being re examined this paper should be viewed as a first step towards an assessment of the appropriate role that this more realistic view of cognition should take in different areas of economic theory and also of the desirable characteristics of models that incorporate it

plant closing decisions and the market value of the firm abstract we investigate the underlying causes and the announcement effects of plant closings the closing in our sample do not appear related to takeover activity instead they appear motivated by declining firm profitability firms announcing closings have lower earnings than market or industry medians earnings typically improve slightly after the announcement we find a negative stock market reaction to plant closing announcements

is technical analysis in the foreign exchange market profitable a genetic programming approach using genetic programming techniques to find technical trading rules we find strong evidence of economically significant out of sample excess returns to those rules for each of six exchange rates over the period 1981 1995 further when the dollar deutsche mark rules are allowed to determine trades in the other markets there is significant improvement in performance in all cases except for the deutsche mark yen betas calculated for the returns according to various benchmark portfolios provide no evidence that the returns to these rules are compensation for bearing systematic risk bootstrapping results on the dollar deutsche mark indicate that the trading rules detect patterns in the data that are not captured by standard statistical models

capital market effects of u s canada gaap differences canadian firms that list securities on u s stock exchanges are generally required to provide a reconciliation of reported income measured using canadian generally accepted accounting principles gaap to reported earnings measured using u s gaap this paper examines both the magnitudes and the information content of the reported reconciliations between canadiangaap income and u s gaap income two recent studies of cross country gaap differences do not address u s canada differences because of perceived similarities between gaap in the two countries amir harris and venuti 1993 and mcqueen 1993 if u s canada gaap differences are in fact unimportant then no further examination is warranted professional bodies however are

additional evidence on bonus plans and income management abstract we extend healy 1985 by examining the relation between discretionary accruals and bonus plan bounds for a sample of 102 firms for the 1980 1990 period contrary to healy we find that when earnings before discretionary accruals fall below the lower bound managers select income increasing discretionary accruals and vice versa we believe that our results are more consistent with the income smoothing hypothesis than with healy s bonus hypothesis however mechanical selection bias in portfolio formation cannot be entirely ruled out as an alternative explanation for our results

multiple maturities and time varying risk premia in forward exchange markets abstract this paper derives the necessary conditions for an intertemporal optimization problem faced by an international investor who can enter forward contracts of several maturity dates and simultaneously borrow in domestic money markets the model parameters are estimated and the overidentifying restrictions are tested using hansen s proposed gmm technique the restrictions are strongly rejected when forward premia are used as instruments the risk neutral specification is rejected when expenditures on non durables and services are used as the consumption measure possible explanations for these rejections are provided

econometrics of the basu asymmetric timeliness coefficient and accounting conservatism a substantial literature investigates conditional conservatism defined as asymmetric accounting recognition of economic shocks news and how it depends on various market political and institutional variables studies typically assume the basu 1997 asymmetric timeliness coefficient the incremental slope on negative returns in a piecewise linear regression of accounting income on stock returns is a valid conditional conservatism measure we analyze the measure s validity in the context of a model with accounting income incorporating different types of information with different lags and with noise we demonstrate that the asymmetric timeliness coefficient varies with firm characteristics affecting their information environments such as the length of the firm s operating and investment cycles and its degree of diversification we particularly examine one characteristic the extent to which unbooked information such as revised expectations about rents and growth options is independent of other information and discuss the conditions under which a proxy for this characteristic is the market to book ratio we also conclude that much criticism of the basu regression misconstrues researchers objectives

learning to reoptimize consumption at new income levels a rationale for prospect theory this paper provides a theoretical rationale for three experimental results of prospect theory risk preferences are over gains and losses loss aversion and diminishing sensitivity we consider a boundedly rational decision maker who does not e nd her new optimal consumption bundle with certainty when she is faced with a new income level this alters her indirect utility function and makes her more risk averse at her current reference income level and less risk averse for a range of incomes below her reference income level jel d11

the optimal pricing of exports invoiced in different currencies abstract the paper presents a model of optimal pricing of exports invoiced in different currencies integrating export pricing with exchange risk management the model maximizes the present value of an exporter s profits from sales in different currencies in the presence of covered interest arbitrage exchange risk and transactions costs given the corresponding cost minimization by the buyers it turns out that the optimal prices in the different currencies are equal at the spot exchange rate only by chance if all the other conditions for the equality of the prices are satisfied it is optimal to set a lower export price in the currency with the lower interest rate and a higher price in the currency with the higher interest rate in order to induce the buyers to pay in the currency offering the lower interest rate the effects on the optimal prices of factors such as interest rates spot exchange rates the buyers and seller s exchange rate expectations and initial foreign exchange positions as well as demand elasticities are analyzed in detail the paper shows that the observed pass through of exchange rates to prices of less than 100 is consistent with optimality
