inconsistent voting behaviour in the fomc this article uses transcript data to examine determinants of inconsistent voting behaviour in the federal open market committee fomc in the period 1989 2008 inconsistent voting behaviour occurs

regional house price dynamics and voting behavior in the fomc i introduction interest rate decisions by the federal open market committee fomc are not always made unanimously different individual views about the appropriate monetary policy stance may lead to the result that members cast dissenting interest rate votes in fomc meetings that is they opt for a higher or lower interest rate than proposed by the chairman of the fomc several studies find that fomc members have different views about the appropriate monetary policy when casting interest rate votes belden 1989 chappell and mcgregor 2000 chappell mcgregor and vermilyea 2005 2008 2012 gildea 1990 1992 havrilesky and gildea 1991 1995 havrilesky and schweitzer 1990 meade and sheets 2005 meade 2010 tootell 1991 1996 an important source of such dissenting votes may be the regional bias of the fomc member which is constituted by its regional affiliation several studies have examined the impact of the regional unemployment rate on the interest rate votes of fomc members while gildea 1992 meade and sheets 2005 and chappell mcgregor and vermilyea 2008 find that a higher regional unemployment rate relative to the national rate increases decreases fomc members preference for monetary easing tightening tootell 1991 finds no significant evidence 1 in this article we analyze whether fomc members align their interest rate voting behavior with house price developments of the federal reserve district they represent in addition to the regional unemployment rate studied so far in this way we can test whether regional house prices and or regional unemployment rates have a significant impact on the voting behavior of fomc members and we examine whether there are systematic differences between regional bank presidents and board members various studies have examined the link between monetary policy and asset price developments according to gilchrist and leahy 2002 there are some good reasons why central banks should align their monetary policies with asset prices first the consumer price index cpi or gross domestic product gdp deflator are incomplete measures since they only signal information on the prices of goods consumed today whereas a more complete measure would also signal future cost of living such as the information contained in asset prices alchian and klein 1973 second asset prices may be useful in forecasting inflation goodhart and hofmann 2000 third asset prices may directly affect real economic activity and inflation since for example wealthier consumers spend more which may affect price developments carroll otsuka and slacalek 2011 whether central banks should react to asset prices is however debated in the literature the traditional view is that central banks should only react to asset prices to the extent that they feed back into the conventional monetary policy goals inflation and output bernanke and gertler 1999 2001 on the contrary cecchetti et al 2000 conclude that it may be reasonable for central banks to react to asset prices in particular house prices in order to avoid the buildup of asset price bubbles as the burst of asset price bubbles may lead to financial crises reinhart and rogoff 2009 leaning against the buildup of extreme asset price changes may therefore be a reasonable choice for central banks as a part of their mission to manage systemic risk allen and carletti 2009 bordo and jeanne 2002 another rationale that central banks should take asset prices particularly house prices into account is that house prices have been shown to be suitable early warning indicators for the outbreak of the recent financial crisis kemme and roy 2012 several empirical papers analyze the impact of asset prices on interest rate setting rigobon and sack 2003 and dupor and conley 2004 find evidence that fomc interest rate decisions are influenced by equity prices on the contrary fuhrer and tootell 2008 find that fomc interest rate decisions are not a direct response to equity price movements and are an indirect response only to the extent that equity prices helped forecast the conventional monetary policy goals

the pricing of options on assets with stochastic volatilities one option pricing problem that has hitherto been unsolved is the pricing of a european call on an asset that has a stochastic volatility this paper examines this problem the option price is determined in series form for the case in which the stochastic volatility is independent of the stock price numerical solutions are also produced for the case in which the volatility is correlated with the stock price it is found that the black scholes price frequently overprices options and that the degree of overpricing increases with the time to maturity one option pricing problem that has hitherto remained unsolved is the pricing of a european call on a stock that has a stochastic volatility from the work of merton 12 garman 6 and cox ingersoll and ross 3 the differential equation that the option must satisfy is known the solution of this differential equation is independent of risk preferences if a the volatility is a traded asset or b the volatility is uncorrelated with aggregate consumption if either of these conditions holds the risk neutral valuation arguments of cox and ross 4 can be used in a straightfoward way this paper produces a solution in series form for the situation in which the stock price is instantaneously uncorrelated with the volatility we do not assume that the volatility is a traded asset also a constant correlation between the instantaneous rate of change of the volatility and the rate of change of aggregate consumption can be accommodated the option price is lower than the blackscholes b s 1 price when the option is close to being at the money and higher when it is deep in or deep out of the money the exercise prices for which overpricing by b s takes place are within about ten percent of the security price this is the range of exercise prices over which most option trading takes place so we may in general expect the b s price to overprice options this effect is exaggerated as the time to maturity increases one of the most surprising implications of this is that if the b s equation is used to determine the implied volatility of a near the money option the longer the time to maturity the lower the implied volatility numerical solutions for the case in which the volatility is correlated with the stock price are also examined the stochastic volatility problem has been examined by merton 13 geske 7 johnson 10 johnson and shanno 11 eisenberg 5 wiggins 16 and

spot and forward volatility in foreign exchange this paper investigates the empirical relation between spot and forward implied volatility in foreign exchange we formulate and test the forward volatility unbiasedness hypothesis which is the volatility analogue to the extensively researched hypothesis of unbiasedness in forward exchange rates using a new data set of spot implied volatility quoted on over the counter currency options we compute the forward implied volatility that corresponds to the forward contract on future spot implied volatility known as a forward volatility agreement we nd statistically signi cant evidence that forward implied volatility is a systematically biased predictor that overestimates future spot implied volatility the bias in forward volatility generates high economic value to an investor exploiting predictability in the returns to volatility speculation and indicates the presence of predictable volatility term premiums in foreign exchange

option prices and the underlying asset s return distribution this work examines the relation between option prices and the true as opposed to risk neutral distribution of the underlying asset if the underlying asset follows a diffusion with an instantaneous expected return at least as large as the instantaneous risk free rate observed option prices can be used to place bounds on the moments of the true distribution an illustration of the paper s results is provided by the analysis of the information concerning the mean and standard deviation of market returns contained in the prices of s p 100 index options although it seems natural that the prices of claims to various parts of the underlying asset s distribution should contain information about the shape of that distribution cox and ross 1976 established that an option s price equals its expected payoff discounted at the risk free rate where the expectation is taken over the risk neutral rather than the true distribution of the underlying asset linking the risk neutral distribution implicit in option prices to the true distribution remains a comparative mystery a necessary condition for the risk neutral pricing methodology to be applicable is that the true and the risk neutral distribution share a common support the only information about the true distribution that can be obtained from observed option prices alone is information about that support this paper demonstrates though that observed option prices when used in conjunction with simple assume d restrictions on the true distribution do contain information about the noncentral moments of the true distribution not directly implied by those assumed restrictions alone the intuition for the result that option prices can be useful in placing bounds on the moments of the true distribution is straightforward first we generalize the results in lo 1987 to show how the expected payoff to a call can be bounded above in terms of any chosen set of the noncentral moments of the return on the underlying asset second we establish restrictions on the

forecast dispersion dissenting votes and monetary policy preferences of fomc members the role of individual career characteristics and political aspects using data from 1992 to 2001 we study the impact of members economic forecasts on the probability of casting dissenting votes in the federal open market committee fomc employing standard ordered probit techniques we find that higher individual inflation and real gdp growth forecasts relative to the committee s median significantly increase the probability of dissenting in favor of tighter monetary policy whereas higher individual unemployment rate forecasts significantly decrease it using interaction models we find that fomc members with longer careers in government industry academia non governmental organizations ngos or on the staff of the board of governors are more focused on output stabilization while fomc members with longer careers in the financial sector or on the staffs of regional federal reserve banks are more focused on inflation stabilization we also find evidence that politics matters with republican appointees being much more focused on inflation stabilization than democratic appointees moreover during the entire clinton administration natural monetary policy preferences of bank presidents and board members for inflation and output stabilization were more pronounced than under periods covering the administrations of both george h w bush and george w bush respectively

recovering probability distributions from option prices this article derives underlying asset risk neutral probability distributions of european options on the s p 500 index nonparametric methods are used to choose probabilities that minimize an objective function subject to requiring that the probabilities are consistent with observed option and underlying asset prices alternative optimization specifications produce approximately the same implied distributions a new and fast optimization technique for estimating probability distributions based on maximizing the smoothness of the resulting distribution is proposed since the crash the risk neutral probability of a three four standard deviation decline in the index about 36 percent 46 percent over a year is about 10 100 times more likely than under the assumption of lognormality recently the increasing popularity of derivatives and some highly publicized failures to control risk have led to increased efforts to find reasonable methods to measure the sensitivity of large institutional derivatives portfolios to extreme events merely because such events are rare is not sufficient to ignore them since on the few occasions when they do occur significant amounts of money can change hands potentially wiping out profits accumulated over long prior periods a key assumption behind methods of estimation is the joint probability distribution of constituent underlying asset returns this has long been a concern of financial economists since probability assumptions are critical to much of their research during the last quarter century heretofore probability distributions of stock market returns have typically been estimated from historical time series unfortunately common hypotheses may not capture the probability of extreme events and the events of interest are rare or may not be present in the historical record even though they are clearly possible

rare disasters and exchange rates we propose a new model of exchange rates which yields a theory of the forward premium puzzle our explanation combines two ingredients the possibility of rare economic disasters and an asset view of the exchange rate our model is frictionless has complete markets and works for an arbitrary number of countries in the model rare worldwide disasters can occur and affect each country s productivity each country s exposure to disaster risk varies over time according to a mean reverting process ri sky countries command high risk premia they feature a depreciated exchange rate and a high interest rate as their risk premium mean reverts their exchange rate appreciates therefore currencies of high interest rate countries appreciate on average to make the notion of disaster risk more implementable we show how options prices might in principle uncover latent disaster risk and help forecast exchange rate movements we then extend the framework to incorporate two factors a disaster risk factor and a business cycle factor we calibrate the model and obtain quantitatively realistic values for the volatility of the exchange rate the forward premium puzzle regression coefficients and near random walk exchange rate dynamics finally we solve a model of stock markets across countries which yields a series of predictions about the joint behavior of exchange rates bonds options and stocks across countries the evidence from the options market appears to be supportive of the model jel e43 e44 f31 g12 g15

monetary policy committees and interest rate setting abstract this paper shows that it is preferable for monetary policy to be conducted by a committee instead of a single policy maker if there is uncertainty about potential output we examine three decision procedures an optimal procedure averaging and voting and find that the latter is the appropriate way to reach decisions if policy makers are not equally skilled finally we demonstrate that efficient decision procedures reduce the persistence of shocks

anti herding and strategic consultation in this paper i analyze how careerist decision makers aggregate and use information provided by others i find that decision makers who are motivated by reputation concerns tend to anti herding i e they excessively contradict public information such as the prior or others recommendations i also find that some decision makers may deliberately act unilaterally and not consult advisers although advice is costless moreover advisers to the decision maker may not report their information truthfully even if the advisers care only about the outcome they bias their recommendation since they anticipate inefficient anti herding behavior by the decision maker

the statistical properties of daily foreign exchange rates 1974 1983 abstract this paper examines the statistical properties of daily rates of change of five foreign currencies from 1974 to 1983 the main purpose is to discriminate between two competing explanations for the observed heavy tails of the distribution that the data are independently drawn from a heavy tail distribution which remains fixed over time and that the data come from distributions which vary over time evidence point to the rejection of the first hypothesis further investigations show that the rejection can be attributed to changing means and variances in the data which can be described by a simple statistical model

using option prices to estimate realignment probabilities in the european monetary system the case of sterling mark abstract this paper describes a procedure for estimating the market s perceived probability distribution of future exchange rates from the prices of risk reversals strangles and other currency options and uses the procedure to estimate the risk neutral ex ante probability of a realignment of the pound sterling the procedure for estimating the realignment probabilities relies on the jump diffusion model of exchange rate behavior and the resulting option pricing formula by fitting this model to market option price data i retrieve the unobserved parameters of the jump diffusion process i then use these parameter estimates to estimate the ex ante probability distribution of exchange rates and thus the realignment probabilities

the economics of career concerns part i comparing information structures many incentives in organizations arise not through explicit formal incentive contracts but rather implicitly through career concerns this paper models career concerns through agents trying to manipulate the market assessment of their future productivity the information flow from current actions to market assessment is therefore crucial in determining the nature of these incentives improved information may either increase or reduce incentives the impact of information provides a major distinction between the explicit and implicit incentives model the paper derives general results on comparisons of information structures which serve as counterparts to the standard results on information structures in the principal agent model sufficient statistic impact of a blackwell garbling comparison of inclusive information structures 1999 the review of economic studies limited

publicity of debate and the incentive to dissent evidence from the us federal reserve transparency in committee decision making may have clear benefits by making members more accountable to outside observers we consider one potential cost the possibility that publishing records of deliberations will make members more reluctant to offer dissenting opinions we construct a model that compares incentives for members with career concerns to voice dissent when deliberations occur in public or in private we test the model using an original dataset based on deliberations of the federal reserve s federal open market committee asking whether the fomc s 1993 decision to begin releasing transcripts of its meetings has altered incentives for dissent we find evidence that this is indeed the case there has been much recent discussion of the advantages of transparency in agency relationships both in and outside of government while research has attempted to model this issue theoretically there has been less progress with empirical tests a problem due no doubt in large part to the fact that it is difficult to make before and after comparisons of a shift in transparency often no data are available on an agent s actions prior to the establishment of transparency in this article we focus on one specific type of transparency publishing verbatim transcripts of committee meetings and one specific reason why this type of transparency might not be desirable the possibility that the quality of deliberation on a committee will suffer if the deliberations take place in public we develop a theoretical model that helps to identify the potential costs of this type of transparency and we then test the model empirically using an original dataset on deliberations of the federal reserve s federal open market committee fomc our dataset is unique in that it records views expressed by policymakers at fomc meetings and not just their official votes our empirical tests focus in particular on the observed effect of the institutional change that occurred in 1993 when the fomc decided to begin releasing transcripts of its meetings after a delay of five years transparency is a particularly relevant issue in monetary policy because it is commonly argued that when central banks take actions such as publishing macroeconomic forecasts revealing individual votes on monetary policy committees or releasing minutes of meetings this will lead to improved economic outcomes while simultaneously facilitating democratic accountability 1

arbitrage based tests of target zone credibility evidence from erm cross rate options this paper introduces two arbitrage based tests of target zone credibility using a new data source exchange rate mechanism cross rate options using daily option prices from september 1991 to august 1994 the authors assess the credibility of the pound mark and mark lira target zones that collapsed in september 1992 and the ongoing mark french franc target zone these tests are based on restrictions that must apply to all option prices within a credible target zone and are free from specification error and estimation error the authors also identify a minimum intensity of realignment an expression indicating the probability weighted average realignment size copyright 1996 by american economic association

an interpretation of recent research on exchange rate target zones how do exchange rate bands work compared to completely fixed rates between realignments or more precisely what are the dynamics of exchange rates interest rates and central bank interventions within exchange rate bands does the difference between bands and completely fixed exchange rates matter and if so which of the two arrangements is best or more precisely what are the tradeoffs that determine the optimal bandwidth this article will present an interpretation of some selected recent theoretical and empirical research on exchange rate target zones with emphasis on main ideas and results and without technical detail

common factors and local factors implications for term structures and exchange rates this paper studies a multi factor two country term structure and exchange rate model when a diversification effect for an international bond portfolio is expected it shows that the diversification gain calls upon certain restrictions on the process of the stochastic discount factor in a factor structured economy existence of local factors is shown to be a necessary condition for the gains from investing in foreign bonds further the exchange rate risk premia are shown to be a function of the differentials of the risk premia of the factors in bond returns empirical results reveal the tendency for investors to respond sensitively to rare shocks which is shown to be a potential solution to the forward premium puzzle

managerial incentive problems a dynamic perspective the paper studies how a person s concern for a future career may influence his or her incentives to put in effort or make decisions on the job in the model the person s productive abilities are revealed over time through observations of performance there are no explicit output contingent contracts but since the wage in each period is based on expected output and expected output depends on assessed ability an implicit contract links today s performance to future wages an incentive problem arises from the person s ability and desire to influence the learning process and therefore the wage process by taking unobserved actions that affect today s performance the fundamental incongruity in preferences is between the individual s concern for human capital returns and the firm s concern for financial returns the two need be only weakly related it is shown that career motives can be beneficial as well as detrimental depending on how well the two kinds of capital returns are aligned it is well understood by now that informational externalities may place special demands on the organization of economic exchange simple price mediated markets will frequently fail in the presence of asymmetric information in that case more elaborate contractual arrangements have to be used as substitutes for the price system lately considerable effort has been devoted to the analysis of contracting under incomplete information with the objective to understand the range of economic institutions that emerge in response to the failure of the price system the analysis of moral hazard has played a prominent role in this development moral hazard problems arise when for some reason or another transacting parties cannot contract contingent on the delivery of the good for instance in buying labour services it may be that the amount of labour supplied is not directly observable precluding a simple exchange of wage for labour as a partial remedy to this problem an imperfect mutually observed signal about the supply of labour can be used as a proxy in the contract frequently output is taken as such a proxy the drawback is that output is often influenced by other factors than labour input which induce undesirable risk into the contract one is therefore faced with a tradeoff between allocating risk associated with incomplete observability and providing incentives for a proper supply of labour gaining insight into this tradeoff is important not only for understanding contracting in the small e g managerial incentive schemes but also because it is closely related to the fundamental tension between equity and efficiency in the society as a whole while our understanding of moral hazard has advanced a lot in past years it is clear that much work remains an important question that has received little attention until

deliberation and learning in monetary policy committees i introduction recent theoretical and experimental work on the monetary policy decision process supports the argument that committees may make better policy decisions than individuals e g blinder 2007 blinder and morgan 2005 gerlach kristen 2006 lombardelli proudman and talbot 2005 blinder 2004 38 39 offers four reasons why monetary policy committees mpcs might make better choices than individuals first when members have different preferences diversification avoids extreme outcomes second even if members have similar preferences they might use different models to reach their conclusions third members might use different forecasts or forecasting techniques finally individuals might use different modes of reasoning or heuristics to approach problems the last three reasons in blinder s list suggest that members bring distinct perspectives or information to a committee meeting deliberation in the committee meeting requires members to confront their differences and could result in both learning and better policy decisions former bank of england mpc member richard lambert 2005 and former federal reserve bank of boston president cathy minehan 2006 have pointed to the importance of deliberation in mpc meetings particularly revealing are minehan s 2006 comments about her experience on the federal open market committee fomc one highly important element in dealing with uncertainty is the strength of the committee itself in that regard it is perhaps fashionable to deride committee decision making in general as bureaucratic and cumbersome my view is that in situations where there are many possible philosophical approaches and a lot at stake a committee helps its members to both see all aspects of the issue and weigh the risks and costs of a particular decision as with other vital institutions like the supreme court there is value to a committee decision on policy versus one taken by a single executive the importance of deliberation in various decision making contexts has also been addressed in political science austen smith and feddersen 2006 contribute to the literature on jury deliberation by offering a theoretical analysis of how different voting rules shape voters incentives to share information prior to a vote being taken barabas 2004 finds evidence that deliberation is an effective way to disseminate information and shape opinions about public policy issues u s supreme court justice stephen breyer has explained how deliberation matters in supreme court conferences cited in brafman and brafman 2009 kindle location 1764 if someone is going to write a dissent they have a point they have some kind of point they re trying to make quite often the opinion of the majority is changed somewhat in response to comments and opinions of the dissenters occasionally maybe once or twice a year the whole court shifts even when dissenters do not have enough votes to change the court s opinion they still affect the process it makes the other person take account of the point they have to answer it or they have to take it into account breyer said in the case of the fomc bailey and schonhardt bailey 2008 use a full text content analysis of the 1979 and 1980 fomc transcripts to study the importance of deliberation in the decision to shift to anti inflationary policy under chairman paul volcker they conclude that deliberation in the fomc did indeed matter both in 1979 and 1980 p 404 as volcker led his colleagues to adopt a new operating procedure and maintain a more restrictive monetary policy stance bailey and schonhardt bailey 2009 extend their analysis to the 1979 1999 period and find that the role of deliberation declined from the volcker era to the greenspan era woolley and gardner 2009 concur with this result even in light of previous theoretical and empirical work on deliberation though bailey and schonhardt bailey 2009 22 nevertheless argue that too little attention has been given to understanding the process of deliberation in policymaking and how this yields outcomes decisions and the quality of those outcomes

the persuasive power of a committee chairman arthur burns and the fomc this paper investigates persuasion as a means of influence for the federal reserve chairman in meetings of the federal open market committee fomc using textual records of fomc meetings federal funds rate targets have been recorded for committee members who served in the arthur burns era 1970 1978 results show that burns member differences in stated funds rate targets were lower when burns made recommendations early in the meeting consistent with the hypothesis that the chairman is persuasive additional results show that members tendencies to respond to burns s recommendations were related to their personal and political loyalties

recovering risk neutral densities from option prices a new approach in this paper we present a new method of approximating the risk neutral density rnd from option prices based on the c type gram charlier series expansion gcse of a prob ability density function the exponential form of this type of gcse guarantees that it will always give positive values of the risk neutral probabilities and it can allow for stronger deviations from normality which are two drawbacks of the a type gcse used in practice to evaluate the performance of the suggested expansion of the rnd the paper presents simulation and empirical evidence

deliberation preference uncertainty and voting rules a deliberative committee is a group of at least two individuals who first debate about what alternative to choose prior to these same individuals voting to determine the choice we argue first that uncertainty about individuals private preferences is necessary for full information sharing and second demonstrate in a very general setting that the condition under which unanimity can support full information revelation in debate amounts to it being common knowledge that all committee members invariably share identical preferences over the alternatives it follows that if ever there exists an equilibrium with fully revealing debate under unanimity rule there exists an equilibrium with fully revealing debate under any voting rule moreover the converse is not true of majority rule if there is uncertainty about individuals preferences

are two heads better than one monetary policy by committee two experiments were conducted to test the common hypothesis that groups make decisions more slowly than individuals one of these experiments imitates real life monetary policy decisions in both cases the hypothesis is found wanting groups are not slower than individuals in both experiments we also find that group decisions are on average better than individual decisions this holds regardless of whether the groups make decisions by unanimity or majority rule simple mechanical theories of group decisionmaking that the group follows its average player median player or best player do not explain the results group interactions seem to matter

is the mpc s voting record informative about future uk monetary policy it is shown that the voting record of the monetary policy committee of the bank of england helps predict future policy rate changes this result is robust to the inclusion of market participants expectations as measured by the slope of the term structure of money market rates and interest rate futures moreover expectations seem to adjust to the information contained in the voting record which suggests that publishing the minutes of mpc meetings increases the transparency of monetary policy

forecasting stock return variance toward an understanding of stochastic implied volatilities we examine the behavior of measured variances from the options market and the underlying stock market under the joint hypotheses that markets are informationally efficient and that option prices are explained by a particular asset pricing model forecasts from time series models of the stockreturn process should not have predictive content given the market forecast as embodied in option prices both in sample and out of sample tests suggest that this hypothesis can be rejected using simulations we show that biases inherent in the procedure we use to imply variances cannot explain this result thus we provide evidence inconsistent with the orthogonality restrictions of option pricing models that assume that variance risk is unpriced these results also have implicationsfor optimal variance forecast rules

confidence building on euro convergence evidence from currency options we study the evolution of investor confidence in 1992 1998 over the chance of individual currencies to converge to the euro using data on currency option prices convergence risk which may reflect uncertainty over policy commitment as well as exogenous fundamentals induces a level of implied volatility in excess of actual volatility this volatility wedge should gradually decrease as confidence grows over time as convergence policy is maintained and the risk of a reversal is progressively resolved empirically we indeed find a positive volatility wedge which declines over time only for currencies involved in the euro convergence process the wedge and other convergence risk measures are correlated with both exogenous fundamentals and proxies for policy commitment uncertainty we also find that the wedge responds to policy shocks in an asymmetric fashion suggesting that policy risk is resolved at different rates after negative and positive shocks finally we estimate a regime switching model of convergence uncertainty using data on interest rates currency rates and currency option prices the results confirm the time varying and asymmetric nature of convergence risk and indicate that investors demand a risk premium for convergence risk

the choice of titling system in land abstract this paper analyzes the choice of the socially optimal titling system assuming rational individual choices about recording assurance and registration decisions it focuses on the enforcement of property rights to land under private titling and the two existing public titling systems recording and registration when the reduction in the expected costs of forfeiture balances the higher cost of initial registration a registration system is more efficient than a recording system implications for title assurance land improvements and transactions are also considered

the crash of ʼ87 was it expected the evidence from options markets transactions prices of s p 500 futures options over 1985 1987 are examined for evidence of expectations prior to october 1987 of an impending stock market crash first it is shown that out of the money puts became unusually expensive during the year preceding the crash second a model is derived for pricing american options on jump diffusion processes with systematic jump risk the jump diffusion parameters implicit in options prices indicate that a crash was expected and that implicit distributions were negatively skewed during october 1986 to august 1987 both approaches indicate no strong crash fears during the 2 months immediately preceding the crash attempts to explain what caused the stock market crashes around the world in october 1987 have suffered from the paucity of major economic developments occurring around that time that could have triggered the crashes shifting expectations regarding monetary policy foreign investors fears of a dollar decline increasing riskiness of assets none of these appeared major enough if present at all to explain the magnitude of the crashes and although portfolio insurance strategies could conceivably magnify the effects of a jump in fundamentals the initiating jump in fundamentals appears to be lacking

predicting volatility in the foreign exchange market measures of volatility implied in option prices are widely believed to be the best available volatility forecasts in this article we examine the information content and predictive power of implied standard deviations isds derived from chicago mercantile exchange options on foreign currency futures the article finds that statistical time series models even when given the advantage of ex post parameter estimates are outperformed by isds isds however also appear to be biased volatility forecasts using simulations to investigate the robustness of these results the article finds that measurement errors and statistical problems can substantially distort inferences even accounting for these however isds appear to be too variable relative to future volatility it is widely believed that the volatility implied in option prices is the market s best estimate of future volatility after all if it were not one could devise a trading strategy that could generate profits by identifying mispriced options the purpose of this article is to investigate the information content and predictive power of volatility implied in options on foreign currencies the paper focuses on options on currency futures traded on the chicago mercantile exchange cme because of the depth and liquidity of cme futures and options traded side by side in the same market implied standard deviations isds allow for clean tests of the predictive power of implied volatilities early studies of the information content of isds have generally found that these contain substantial information for future volatility latane and rendleman 1976 chiras and manaster 1978 and beckers 1981 for example regress future volatility on the weighted implied volatility across a broad sample of chicago board options exchange cboe stocks and find that options contain volatility forecasts that are more accurate than historical measures 1 these studies performed shortly after the 1973 beginning of the cboe option market could only use a relatively short time span and therefore focused on cross sections rather than time series predictions

learning from the behavior of others conformity fads and informational cascades learning by observing the past decisions of others can help explain some otherwise puzzling phenomena about human behavior for example why do people tend to converge on similar behavior why is mass behavior prone to error and fads the authors argue that the theory of observational learning and particularly of informational cascades has much to offer economics business strategy political science and the study of criminal behavior

recovering an asset s implied pdf from option prices an application to crude oil during the gulf crisis we develop a general method for estimating the implied martingale equivalent probability density function pdf for futures prices from american options prices the early exercise feature of american options precludes expressing the price of the option in terms of the pdf there exist tight bounds for the price of american options in terms of the pdf we demonstrate how these bounds together with observed option prices can be used to estimate the parameters of the pdf we estimate the distribution for crude oil during the persian gulf crisis and find the distribution differs significantly from that recovered using standard techniques

the intensity and timing of investment the case of land the authors model the decision to replace durable capital when intensity is variable decisions of this type include land redevelopment decisions where the density of residential or commercial development is a choice variable as well as capital replacement decisions where capacity is variable the authors provide a general yet simple formation of the problem using an optimal stopping framework they characterize the value of the project the timing of investment and the intensity of development the authors show that intensity interacts in important ways with timing taxes and project values the ability to vary intensity raises hurdle rents and delays development decisions copyright 1994 by american economic association

strategic urban projects in amsterdam and new york incomplete contracts and good faith in different legal systems contracts between local government and private investment agencies play an important role in strategic urban projects real estate cycles provide only a narrow window of opportunity within which to draft such contracts a legal system should therefore not impede the possibility of reaching an agreement quickly instead it should facilitate efficient ways of reaching an agreement lengthy contracting may contribute to the persistence of real estate market cycles this paper explores the question of whether the civil law principle of good faith facilitates the drafting of incomplete contracts which may be efficient in situations of high uncertainty and complexity as was the case with two strategic inner city projects the south axis in amsterdam and battery park city in new york city the paper further establishes that good faith does play a considerable role in the differences in contracting practice

a theory of yes men this paper illustrates an incentive for workers to conform to the opinion of their supervisors when firms use subjective performance evaluation this desire to conform arises endogenously from the firm s need to induce the worker to exert effort the author shows that firms may optimally eschew the use of incentive contracts to retain workers incentives for honesty the author illustrates that the incentive to conform implies inefficiencies even when workers are risk neutral and is likely to lead to more centralized decision making than in the absence of the desire to conform copyright 1993 by american economic association

information aggregation in debate who should speak first abstract privately informed individuals speak openly in front of other members of a committee about the desirability of a public decision each individual wishes to appear well informed for any given order of speech committee members may herd by suppressing their true information with individuals of heterogeneous expertise optimizing over the order of speech can improve the extraction of information but not perfectly so it is not always optimal to use the common anti seniority rule whereby experts speak in order of increasing expertise a committee with more able experts may be afflicted by greater herding problems yielding a worse outcome

target zones and realignments recent contributions emphasize that the presence of exchange rate target zones has important effects on the within band behavior of exchange rates when agents are forward looking the authors find that the implications of available models are inconsistent with european exchange rate data and they suggest that the frequent realignments occurring in the period they consider may be responsible for this they construct a model in which the likelihood of a realignment in the near future increases as the exchange rate approaches the limits of its fluctuation band and show that its implications are broadly consistent with the evidence copyright 1992 by american economic association

the dynamic effects of land title systems abstract the question of title concerns which specific individual enjoys the property rights to a particular parcel of land when there are competing claims this paper examines how the title system affects urban development in a market economy it considers two alternative title systems recording and registration both hasten the development pace relative to the social planner benchmark but the registration system is generally closer than the recording system to the benchmark the effects of the two systems on the capital land ratio depend on whether the demanded capital land density is rising or falling over time

erm bandwidths for emu and after evidence from foreign exchange options ems credibility exchange rate expectations implied by derivatives prices are the wide bands adopted in the summer of 1993 too large the official answer is that wide bands offer a protection against speculative pressure while exchange rates may be kept within narrower margins at the discretion of the authorities yet if exchange rate fixity and predictability are desirable as implicitly assumed by the mere existence of the system there must exist a trade off between protection against speculative pressure and predictability in that case the bandwidth chosen should be as narrow as possible and yet unlikely to be challenged by the markets this paper offers estimates of safe bandwidths for the long term member currencies french franc peseta danish krone and escudo the existing 15 bands are found to be unnecessarily wide narrower 3 5 bands would capture at least 95 of expected exchange rate realizations over a three month horizon for the lira finnish markka and swedish krone wider bands of 5 6 would capture a similar amount of the exchange rate distribution the pound s exchange rate expectations are the most dispersed requiring 8 4 bands to capture 95 of exchange rate expectations jose m campa p h kevin chang and robert l reider

the performance of alternative valuation models in the otc currency options market abstract we compare option valuation models based on regime switching garch and jump diffusion processes to a standard smile model in which black and scholes 1973 implied volatilities are allowed to vary across strike prices the regime switching garch and jump diffusion models provide significant improvement over a fixed smile model in fitting gbp and jpy option prices both in sample and out of sample the jump diffusion model achieves the tightest fit a time varying smile model however provides hedging performance that is comparable to the other models for the gbp options this result suggests that standard option valuation techniques may provide a reasonable basis for trading and hedging strategies

stochastic devaluation risk and the empirical fit of target zone models in the model of this paper an exchange rate fluctuates between given boundaries for random lengths of time and jumps discretely when devaluation occur we provide explicit solutions for the stochastic processes followed by the exchange rate and by the expected rate of depreciation when the likelihood and the size of devaluations vary stochastically over time the model produces realistic patterns of covariation between exchange rates and interest rate differentials and provides interesting interpretations of available empirical evidence we also specify how to infer devaluation risk from target zone data

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

implied exchange rate distributions evidence from otc option markets abstract this paper uses a rich new dataset of option prices on the dollar mark dollar yen and key ems cross rates to extract the entire risk neutral probability density function pdf over horizons of 1 and 3 months we compare three alternative smoothing methods cubic splines an implied binomial tree trimmed and untrimmed and a mixture of lognormals for transforming option data into the pdf despite their methodological differences the three approaches lead to a similar pdf clearly distinct from the lognormal benchmark and typically characterized by skewness and leptokurtosis we then document a striking positive correlation between skewness in these pdfs and the spot rate the stronger a currency the more expectations are skewed towards a further appreciation of that currency we interpret this finding as a rejection that innovations in these exchange rates are independent of the level or characteristic of a credible target zone explicit or implicit instead this positive correlation is consistent with target zones with endogenous realignment risk we discuss two interpretations of our results on skewness when a currency is stronger the actual probability of further large appreciation is higher or because of risk such states are valued more highly

an empirical examination of the variance gamma model for foreign currency options we apply the variance gamma vg option pricing model to currency options the model is a pure infinite activity jump model we examine whether and to what extent this new model can improve the pricing quality for currency options over the existing modified black scholes model and the merton jump diffusion jd model we find that the vg model yields better out of sample pricing performance than the modified black scholes model or the jd model in addition a cross entropy analysis shows that the vg model is more consistent with the general criterion of utility maximization and optimal portfolio selection

majority rule consensus building and the power of the chairman arthur burns and the fomc this paper investigates decision making within the federal open market committee of the federal reserve focusing on the competing pressures of majority rule consensus building and the power of the chairman to undertake this analysis we have constructed an original data set recording desired federal funds rates for each member of the committee over the 1970 78 period our results confirm a disproportionate influence of the chairman in the policy process they also confirm that other voting members of the committee have an impact on policy choices estimates indicate that the chairman exercises 40 to 50 of the voting weight in committee decisions

volatility momentum and time varying skewness in foreign exchange returns this article tests a stochastic volatility model of exchange rates that links both the level of volatility and its instantaneous covariance with returns to pathwise properties of the currency in particular the model implies that the return volatility covariance behaves like a weighted average of recent returns and hence switches signs according to the direction of trends in the data this implies that the skewness of the finite horizon return distribution likewise switches sign leading to time varying implied volatility smiles in options prices the model is fit and assessed using bayesian techniques some previously reported volatility results are accounted for by the fitted models the predicted pattern of skewness dynamics accords well with that found in historical options prices

dollar jump fears 1984 1992 distributional abnormalities implicit in currency futures options abstract deutsche mark and yen futures options over 1984 1992 and 1986 1992 respectively are examined for deviations from the lognormal assumption underlying standard option pricing models two methods are used an atheoretic skewness premium and daily estimates of moments using a model for pricing american foreign currency futures options under systematic exchange rate jump risk substantial variation over time is found in all moments including implicit skewness and kurtosis the implicit abnormalities predict future abnormalities in log differenced dm futures prices but not yen the peso problem implications do not explain standard rejections of uncovered interest parity

the wrong kind of transparency in a model of career concerns for experts when is a principal hurt from observing more information about her agent this paper introduces a distinction between information on the consequence of the agent s action and information directly on the agent s action when the latter kind of information is available the agent faces an incentive to disregard useful private signals and act according to how an able agent is expected to act a priori this conformist behavior hurts the principal in two ways the decision made by the agent is less likely to be the right one discipline and ex post it is more difficult to evaluate the agent s ability sorting the paper identifies a necessary and sufficient condition on the agent signal structure under which the principal bene ts from committing not to observe the agent s action the paper also shows the existence of strategic complementarities between information on action and information on consequence the results on the distinction between action and consequence are then used to interpret existing disclosure policies in delegated portfolio management in particular they are consistent with hitherto puzzling evidence that mutual funds systematically overperform pension funds

simulated likelihood estimation of diffusions with an application to exchange rate dynamics in incomplete markets abstract we present an econometric method for estimating the parameters of a diffusion model from discretely sampled data the estimator is transparent adaptive and inherits the asymptotic properties of the generally unattainable maximum likelihood estimator we use this method to estimate a new continuous time model of the joint dynamics of interest rates in two countries and the exchange rate between the two currencies the model allows financial markets to be incomplete and specifies the degree of incompleteness as a stochastic process our empirical results offer several new insights into the dynamics of exchange rates

exploring the role of the realized return distribution in the formation of the implied volatility smile abstract this article explores the role of the realized return distribution in the formation of the observed implied volatility smile using the framework of an adaptive expectations model according to this framework investors update their expectations of future events through which options are priced by incorporating information from the underlying asset traded in the spot market our study is conducted at the level of cumulants which provide a complete description of investors expectations and can be considered as largely non parametric with a minimal set of assumptions for the stochastic process that drives asset returns the empirical results based on the s p 500 index support the significance of the realized distribution in the formation of the implied volatility smile
