the effect of sporting success and management failure on attendance demand in the bundesliga a revealed and stated preference travel cost approach abstractthis study examines the private consumption benefits of sports attendance using revealed and stated preference data from 28 football bundesliga teams across three divisions survey respondents were presented with positive sporting success and negative management failure scenarios and asked for the number of game trips if each scenario occurred the results of a pooled random effects poisson model show that travel costs and ticket price have a significant negative effect on the number of home game trips the weighted consumer surplus per game trip including travel costs and ticket prices is 345 consumer surplus per game trip was found to change by 41 first division and 98 second and third division if the positive scenario occurred and by 39 if the negative scenario occurred

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

testing the validity of contingent behavior trip responses while a number of validity tests exist for contingent valuation data to date there are very few literature examples for contingent behavior cb data the objective of this study is to test the validity of cb trip data for different levels of rock climbing access using data from surveys implemented before and after a policy restricting recreational access was imposed results from generalized negative binomial and seemingly unrelated poisson regression models show significant sensitivity to scope and suggest that cb data may be a valuable supplement to revealed preference data when policy proposals are outside the range of historical conditions copyright 2002 oxford university press

inferring future volatility from the information in implied volatility in eurodollar options a new approach we study the information content of implied volatility from several volatility specifications of the heath jarrow morton 1992 hjm models relative to popular historical volatility models in the eurodollar options market the implied volatility from the hjm models explains much of the variation of realized interest rate volatility over both daily and monthly horizons the implied volatility dominates the garch terms the glosten et al 1993 type asymmetric volatility terms and the interest rate level however it cannot explain that the impact of interest rate shocks on the volatility is lower when interest rates are low than when they are high article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

implicit delivery options and optimal delivery strategies for financial futures contracts abstract futures contract specification usually allow the short position some variation as to when where how much and what is to be delivered in this paper we derive the optimal delivery policy for the treasury bond futures contracts and find that our policy produces profits that are positive and statistically significant this indicates that future prices are too high in that the short position can earn profits by skillfully exercising his delivery options we find the actual delivery policies of market participants depart substantially from the optimal strategy the implications of these findings for futures traders and bond dealers are discussed

pricing american interest rate claims with humped volatility models abstract some of the most recent empirical studies on interest rate derivatives have found humped shapes in the volatility structure of interest rates in this paper we propose a simple model that allows for humped volatility structures and that can be described by one state variable with the model american style claims can be priced very efficiently which is very important if the model has to be calibrated daily to market prices of standard american options furthermore the model allows for explicit formulas for european style options finally the computational efficiency of our model in the li et al 1995 framework is compared with the efficiency in a typical hull and white 1993a 1994 1996 framework in fact we can use both procedures for our model since we prove that if a deterministic volatility model can be embedded in either of these algorithms then so it does in the other one empirical evidence from option data supporting our model is provided as well

estimating local welfare generated by an nfl team under credible threat of relocation this study offers the opportunity to examine the welfare contribution of the minnesota vikings to minnesota households in the context of a credible threat of team relocation we find the credibility of the threat of relocation is essential to providing unbiased estimates of welfare this study utilizes contingent valuation methodology cvm and a random utility model rum to analyze minnesotans decision making mechanisms for supporting a new stadium initiative while previous studies have attempted to measure the welfare associated with a sports franchise we develop and discuss bias that may be imparted to estimates when the researcher fails to calculate a choke price further we develop an unbiased approach to identify welfare when respondents perceive a risk of losing the franchise the range of welfare contribution by the vikings to households in minnesota is 445 3 million to 1 571 3 million according to a 95 confidence interval based on our study

estimating willingness to pay for a cycling event using a willingness to travel approach abstract this study examines the monetary value of nonmarket benefits to participants of an active sport tourism event such as happiness and pride from participating in an event willingness to travel wtt greater distances for future events is assessed and converted into willingness to pay wtp estimates using travel costs using survey data from the 2014 and 2015 blood sweat gears bike ride the intended visitation models show that changes in travel cost have a significant negative effect wtp to revisit the event was between 41 and 57 the likelihood of return visit decreases as travel costs increase indicating that wtp estimates are internally valid wtp estimates stemming from two years of data collection are stable suggesting that they are also temporally reliable this study demonstrated the feasibility of using stated preference wtt questions to assign a monetary value to nonmarket benefits of active sport tourists

do state trading exporters distort trade abstract in this paper we analyse the trade distorting effects of state trading enterprises stes which exist in some exporting countries because of these potential effects several countries have raised the issue of state enterprises in the doha round negotiations in the wto the belief is that stes in certain developed countries have trade effects which are equivalent to an export subsidy stes also exist in developing countries though since the aim of government policy may differ from the developed country case the trade distortion may be equivalent to an export tax we present a theoretical model that is sufficiently general to allow us to consider the case of exporting stes in developed and developing economies the model is calibrated with data on two examples of stes one typical of an ste in a developed country the other typical of an ste in a developing economy in each case we allow for differences in the nature of the ste s pay off function the overall conclusion is that stes do distort trade and the trade distortion effect is potentially significant

bond pricing and the term structure of interest rates a new methodology for contingent claims valuation this paper presents a unifying theory for valuing contingent claims under a stochastic term structure of interest rates the methodology based on the equivalent martingale measure technique takes as given an initial forward rate curve and a family of potential stochastic processee for its subsequent movements a no arbitrage condition restricts this family of processes yielding valuation formulae for interest rate sensitive contingent claims which do not explicitly depend on the market prices of risk examples are provided to illustrate the key results in relation to the term structure of interest rates arbitrage pricing theory has two purposes the first is to price all zero coupon default free bonds of varying maturities from a finite number of economic fundamentals called state variables the second is to price all interest rate sensitive contingent claims taking as given the prices of the zero coupon bonds this paper presents a general theory and a unifying framework for understanding arbitrage pricing theory in this context of which all existing arbitrage pricing models are special cases in particular vasicek 1977 brennan and schwartz 1979 langetieg 1980 ball and torous 1983 ho and lee 1986 schaefer and schwartz 1987 and artzner and delbaen 1988 the primary contribution of this paper however is a new methodology for solving the second problem i e the pricing of interest rate sensitive contingent claims given the prices of all zero coupon bonds the methodology is new because i it imposes its stochastic structure directly on the evolution of the forward rate curve ii it does not require an inversion of the term structure to eliminate the market prices of risk from contingent claim values and iii it has a stochastic spot rate process with multiple stochastic factors influencing the term structure the model can be used to consistently price and hedge all contingent claims american or european on the term structure and it is derived from necessary and more importantly sufficient conditions for the absence of arbitrage the arbitrage pricing models of vasicek 1977 brennan and schwartz 1979 langetieg 1980 and artzner and delbaen 1988 all require an iformerly titled bond pricing and the term structure of interest rates a new methodology

an analytically tractable interest rate model with humped volatility abstract some of the most recent empirical studies on interest rate derivatives have found humped shapes in the volatility structure of interest rates however this realistic feature has been hardly addressed in theoretical works in this paper we propose an interest rate model which allows for a humped volatility structure and which is analytically tractable in that it leads to explicit formulae for european options on discount bonds empirical evidence supporting the model is also provided

demand for sport this article reviews international literature on the demand for professional sport the first part presents a conceptual framework for understanding the sources and determinants of the demand for professional sporting contests the second part reviews empirical evidence on key determinants of attendance at sporting events and on other sources of demand such as broadcasting sponsorship and merchandising the review concludes that there is still much to be learned about demand for professional sport and that there are no simple lessons to be drawn from existing literature but important messages do emerge from studies of demand for attendance with regard to effects of uncertainty of outcome quality of contest and quality of viewing copyright 2003 oxford university press

on optimal portfolio choice under stochastic interest rates abstract in an economy where interest rates and stock price changes follow fairly general stochastic processes we analyze the portfolio problem of an investor endowed with a non traded cash bond position he can trade on stocks the riskless asset and a futures contract written on the bond so as to maximize the expected utility of his terminal wealth when the investment opportunity set is driven by an arbitrary number of state variables the optimal portfolio strategy is known to contain a pure preference free hedge component a speculative element and merton breeden hedging terms against the fluctuations of each and every state variable while the first two components are well identified and easy to work out the implementation of the last ones is problematic as the investor must identify all the relevant state variables and estimate their distribution characteristics using the martingale approach we show that the optimal strategy can be simplified to include in addition to the pure hedge and speculative components only two merton breeden type hedging elements however large is the number of state variables the first one is associated with interest rate risk and the second one with the risk brought about by the co movements of the spot interest rate and the market prices of risk the implementation of the optimal strategy is thus much easier as it involves estimating the characteristics of the yield curve and the market prices of risk only rather than those of numerous a priori unknown state variables moreover the investor s horizon is shown explicitly to play a crucial role in the optimal strategy design in sharp contrast with the traditional decomposition finally the role of interest rate risk in actual portfolio risk management is emphasized

consumption benefits of national hockey league game trips estimated from revealed and stated preference demand data this paper examines the demand for hockey game trips among metropolitan and nonmetropolitan residents of alberta canada using data on both revealed and stated preference game trip behavior from a telephone survey conducted throughout alberta we estimate the effect of ticket prices team quality arena amenities and capacity on the latent demand for national hockey league hockey games we nd that lower ticket prices higher team quality and additional capacity encourage attendance in the status quo scenario consumer surplus per game is 50 for those who had attended hockey games and about 50 less for those who had not attended games exploiting the stated preference data we develop a number of other consumer surplus estimates we also include travel costs in the estimation of the demand function and estimate the full value of the game trip considering both ticket prices and travel costs sold out arenas in calgary and edmonton generate annual consumption bene ts of 40 and 35 million when only ticket prices are used to calculate consumer surplus i e excluding travel costs considering the full price consumer surplus for the calgary flames of 103 per game trip the annual consumption bene ts may be as high as 82 million jel r22 l83 d61

compensating differentials and the social benefits of the nfl abstract we use hedonic rent and wage equations to measure compensating differentials in central cities and metropolitan areas with franchises of the national football league rents are about 8 percent higher in the central cities but this impact may not carry over to broader geographical areas wages are about 2 percent lower in areas with teams but the standard error on this parameter is large the central city results indicate that sports franchises appear to be a public good once these quality of life benefits are included in the calculus the large public expenditure on new stadiums appears to be a good investment for cities and their residents

analysis of optimal timing of tourism demand recovery policies from natural disaster using the contingent behavior method this paper examines the applicability of contingent behavior hereafter cb method for analyzing dynamic processes and efficient policies in tourism demand recovery the cb questionnaires used for this study used a hypothetical disaster situation of bird flu in kyoto japan safety event visitor information and price discounting policies were designed accordingly respondents were then asked about their willingness to travel time the results showed the optimal timing for devising pertinent policies during the year we found that the first step requires a safety information announcement within one week immediately after disaster site decontamination the second step is the implementation of event information policy within 24th to 36th week after the disaster the third step constitutes announcing visitor information within the 37th to 52nd week after the second step the final step is the implementation of price discounting policy until the 52nd week immediately after the third step

a direct test of the homevoter hypothesis abstract we propose a methodology that facilitates a direct test of the homevoter hypothesis which posits that homeowners vote in favor of public projects they perceive increase residential property values and against those that do not first we estimate how pre referendum events that signal a higher probability that the public project will be undertaken impact local residential property values before the referendum is held these pre referendum impacts are considered noisy signals to homeowners about the market s assessment of the net marginal benefits of the project second we aggregate these market signals to the precinct level and relate them to precinct level voting results concerning the proposed project we apply this two step approach to the 2004 referendum in arlington texas for a publicly subsidized stadium for the nfl dallas cowboys the analysis supports the homevoter hypothesis and establishes a possible methodology for future evaluations in this small but growing empirical literature

the weekend effect on the distribution of stock prices abstract evidence of weekend effects on the distribution of security returns suggests that returns are generated by a process operating closer to trading time rather than calendar time in contrast accumulation of interest over the weekend follows a calendar time process since both the variance of returns and the interest rate are important parameters of the black scholes option pricing model this paper suggests that the model be stated to account for this by utilizing a trading time variance and a calendar time interest rate empirical evidence indicates that this allows the model to better explain market option prices

pricing caps with hjm models the benefits of humped volatility in this paper we compare different multifactor hjm models with humped volatility structures to each other and to models with strictly decreasing volatility all the models are estimated on euribor and swap rates panel data maximizing the quasi likelihood function obtained from the kalman filter we develop the analysis in two steps first we study the in sample properties of the estimated models then we test the pricing performance on caps we find the humped volatility specification to greatly improve the model estimation and to provide sufficiently accurate cap prices although the models has been calibrated on interest rates data and not on cap prices moreover we find the two factor humped volatility model to outperform the three factor models in pricing caps

hedging the risks from writing foreign currency options abstract this paper considers the ways in which banks and other financial institutions can hedge their risks when they write non exchange traded foreign currency options key factors affecting the performance of delta hedging are identified and hedging schemes involving the use of exchange traded options are analyzed the schemes are tested using both simulated data and data from trades on the philadelphia exchange between february 1983 and september 1984

implications of implicit credit spread volatilities on interest rate modelling abstract we test seven term structure models in the heath jarrow and morton 1992 class in order to find the best representation of the libor rate in interest rate markets after the credit crunch of 2007 the libor rate is considered as a risky rate subject to the credit risk of a generic counterparty whose credit quality is refreshed at each fixing date we study the volatilities of the credit spreads implicitly obtained from libor time series in order to understand how assumed volatility functions affect interest rate curve modelling and asset pricing we develop a model to estimate basis swap prices through the monte carlo simulations we compare obtained results and individuate systematic relations existing between the basis spread forecast error and both the accuracy in volatility modelling and the accuracy of the monte carlo estimates we analyse and document these relations by defining appropriate pricing error measures

pricing and hedging interest rate options evidence from cap floor markets we examine the pricing and hedging performance of interest rate option pricing models using dailydata on us dollar cap and floor prices across both strike rates and maturities our results show that fitting the skew of the underlying interest rate probability distribution provides accurate pricing results within a one factor framework however for hedging performance introducing a second stochastic factor is more important than fitting the skew of the underlying distribution this constitutes evidence against claims in the literature that correctly specified and calibrated one factor models could replace multi factor models for consistent pricing and hedging of interest rate contingent claims 2004 elsevier b v all rights reserved

the dynamics of the forward interest rate curve a formulation with state variables the objective of this paper is twofold first the paper develops a class of models of the term structure of interest rates in the heath jarrow and morton 1992 framework with dynamics characterized by the evolution of a small set of state variables second the paper exploits this characterization of the dynamics of the term structure in an estimation exercise that makes use of both the time series and cross section of bond prices in this way our class of models bridges the gap between traditional models such as cox ingersoll and ross 1985 and vasicek 1977 that emphasize the dynamics of interest rates and the models of heath jarrow and morton 1992 that stress fitting the cross section of bond prices

compensating differentials and the social benefit of the nfl reply abstract professors coates humphreys and zimbalist provide a set of suggestions for the model we presented in g carlino n e coulson compensating differentials and the social benefits of the nfl journal of urban economics 56 1 2004 25 50 their two main points provide additional evidence of an nfl effect their remaining points are not persuasive

compensating differentials and the social benefits of the nfl a comment abstract in a recent article in this journal carlino and coulson g carlino n e coulson compensating differentials and the social benefits of the nfl journal of urban economics 56 1 2004 25 50 report evidence that the presence of an nfl franchise in a city raises rents in the central part of the city by about 8 we re estimate their model using several reasonable alternative specifications and find that their results are not robust to these changes the presence of an nfl franchise does not appear to increase rents for center city apartments because their results are not robust to alternative model specifications they should not be used to justify public spending for professional sports facilities

the risk premium of volatility implicit in currency options this article provides an empirical investigation of the risk neutral variance process and the market price of variance risk implied in the foreign currency options market there are three principal contributions first the parameters of heston s mean reverting square root stochastic volatility model are estimated using dollar mark option prices from 1987 to 1992 second it is shown that these implied parameters can be combined with historical moments of the dollar mark exchange rate to deduce an estimate of the market price of variance risk these estimates are found to be nonzero time varying and of sufficient magnitude to imply that the compensation for variance risk is a significant component of the risk premia in the currency market finally the out of sample test suggests that the historical variance and the hull and white implied variance contain no more information than that imbedded in the heston implied variance

term structure movements and pricing interest rate contingent claims this paper derives an arbitrage free interest rate movements model ar model this model takes the complete term structure as given and derives the subsequent stochastic movement of the term structure such that the movement is arbitrage free we then show that the ar model can be used to price interest rate contingent claims relative to the observed complete term structure of interest rates this paper also studies the behavior and the economics of the model our approach can be used to price a broad range of interest rate contingent claims including bond options and callable bonds

combining revealed and stated preference data to estimate the nonmarket value of ecological services an assessment of the state of the science this paper reviews the marketing transportation and environmental economics literature on the joint estimation of revealed preference rp and stated preference sp data the rp and sp approaches are first described with a focus on the strengths and weaknesses of each recognizing these strengths and weaknesses the potential gains from combining data are described a classification system for combined data that emphasizes the type of data combination and the econometric models used is proposed a methodological review of the literature is pursued based on this classification system examples from the environmental economics literature are highlighted a discussion of the advantages and disadvantages of each type of jointly estimated model is then presented suggestions for future research in particular opportunities for application of these models to environmental quality valuation are presented

the relative performance of five alternative warrant pricing models five warrant pricing models are examined in this study a pair based on the black scholes model a pair based on the constant elasticity of variance cev modification and an extendible warrant model a la longstaff based on more than 20 000 warrant price observations the flexible exponent cev model generates the lowest average absolute pricing error in most of the warrants examined the dilution adjusted black scholes model however remains a reasonable economical alternative in many cases

time varying volatilities and calculation of the weighted implied standard deviation rogalski tinic have reported a monthly pattern in ex post stock return variances that differs between small and large market capitalization firms maloney rogalski find that option prices reflect these monthly patterns ex ante this study extends maloney rogalski s work by devising an expiration specific weighted implied standard deviation wisd it is found that i the monthly patterns in one month wisds are basically similar to the monthly patterns in ex post variances detected by rogalski tinic for both large and small size firms and ii use of expiration specific wisds as opposed to standard composite wisds results in improved performance of option pricing models

an empirical comparison of forward rate and spot rate models for valuing interest rate options our main goal is to investigate the question of which interest rate options valuation models are better suited to support the management of interest rate risk we use the german market to test seven spot and forward rate models with one and two factors for interest rate warrants for the period from 1990 to 1993 we identify a one factor forward rate model and two spot rate models with two factors that are not significantly outperformed by any of the other four models further rankings are possible if additional criteria are applied

lattice models for pricing american interest rate claims this article establishes efficient lattice algorithms for pricing american interest sensitive claims in the heath jarrow and morton paradigm under the assumption that the volatility structure of forward rates is restricted to a class that permits a markovian representation of the term structure the class of volatilities that permits this representation is quite large and imposes no severe restrictions on the structure for the spot rate volatility the algorithm exploits the markovian property of the term structure and permits the efficient computation of all types of interest rate claims specific examples are provided

on correlation and default clustering in credit markets we establish markovian models in the heath jarrow and morton 1992 paradigm that permit an exponential affine representation of riskless and risky bond prices while offering significant flexibility in the choice of volatility structures estimating models in our family is typically no more difficult than in the workhorse affine family besides diffusive and jump induced default correlations defaults can impact the credit spreads of surviving firms allowing for a greater clustering of defaults numerical implementations highlight the importance of incorporating interest rate credit spread correlations credit spread impact factors and the full credit spread curve when building a unified framework for pricing credit derivatives the author 2010 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oxfordjournals org oxford university press

customer preferences attendance and the racial structure of professional basketball teams this paper examines the importance of customer based discrimiantion in professional basketball over the 1980 81 to 1985 86 seasons empirical rsesults offer strong support of the hypothesis that if fans prefer to see players of their own race teams will be influenced in their selection of players by the racial composition of their market area by the same token attendance is found to be positively related to the extent to which the racial composition of the team matches that of the corresponding market area

team roster turnover and attendance in major league baseball empirical support is shown for the propositionthat sports fans prefer the composition of their home team to remain the same from season to season controlling for price income population team quality league year the stadium effects the regression results indicate that for each percentage point increase in the turnover of the composition of the team attendance will fall by about 0 7 the implications of this heretofore ignored tendency are briefly discussed

single factor heath jarrow morton term structure models based on markov spot interest rate dynamics this paper considers the class of heath jarrow morton term structure models where the spot interest rate is markov and the term structure at time t is a function of time maturity and the spot interest rate at time t a representation for this class of models is derived and i show that the functional forms of the forward rate volatility structure and the initial forward rate curve cannot be arbitrarily chosen i provide necessary and sufficient conditions indicating which combinations of these functional forms are allowable i also derive a partial differential equation representation of the term structure dynamics that does not require explicit modeling of both the market price of risk and the drift term for the spot interest rate process using the analysis presented in this paper a class of intertemporal term structure models is derived

tests of an american option pricing model on the foreign currency options market this paper tests the ability of the american option pricing model proposed by parkinson 18 or mason 14 to explain the pricing of the foreign currency options traded on the philadelphia stock exchange from february 28 1983 to march 26 1985 we find that the model underprices out of the money options relative to at the money and in the money options this relative underpricing is driven by an underpricing of out of the money call options of short maturity in addition the degree of relative mispricing for most categories of options is shown to be a decreasing function of the time to maturity of the options longer maturity options appear to trade at similar levels of implied volatility whether they are in at or out of the money most of these biases appear consistent with the fact that the underlying spot currency rate follows a mixed jump diffusion process as described in 17

a cyclical square root model for the term structure of interest rates this paper presents a cyclical square root model for the term structure of interest rates assuming that the spot rate converges to a certain time dependent long term level this model incorporates the fact that the interest rate volatility depends on the interest rate level and specifies the mean reversion level and the interest rate volatility using harmonic oscillators in this way we incorporate a good deal of flexibility and provide a high analytical tractability under these assumptions we compute closed form expressions for the values of different fixed income and interest rate derivatives finally we analyze the empirical performance of the cyclical model versus that proposed in cox et al 1985 and show that it outperforms this benchmark providing a better fitting to market data

currency risk hedging futures vs forward abstract the objective of this paper is to address the issue of choosing between currency forward and currency futures contracts when hedging against currency risk within a stochastic interest rates environment we compare between the hedging effectiveness of the two derivative assets both within a narrow sense i e volatility minimization and within a wide sense i e risk return trade off when judging hedging effectiveness in the narrow sense forward and futures contracts give identical results even if they do not have identical prices when judging hedging effectiveness in the wide sense the choice between the two contracts is determined by the correlation between the domestic and the foreign term structures dynamics

the effect of common sources of regression error on benefit estimates discussions of the sources of error in recreation demand analysis are common in the existing literature the most traditional line of thought e g gum and martin considers the error component in predicting the individual s recreation behavior to arise from unmeasured socioeconomic factors others e g hanemann attribute at least some of this error to fundamental randomness in human behavior applied statisticians e g hiett and worrall on the other hand suggest that recall of annual number of recreational trips i e the quantity demanded is subject to substantial error still others e g brown et al have argued that recall of explanatory variables such as travel expenses contains error despite the discussion of potential error sources there is no work which relates the sources of error in the demand relationship with benefit measurement 1 of practical importance in recreational demand estimation is whether error assumptions have an influence on welfare measures since it is for public policy decision purposes that recreational demand estimation is usually undertaken will the estimated consumer surplus derived from demand analysis be independent of the assumed source of the error in the regression the purpose of this paper is to explore how the assumptions about sources of error influence estimates of recreation benefits a discussion of the various sources of error in de

multinationals and agricultural policy in the ec and usa abstract few multinationals have a considerable market share of grain and oilseed trade and processing industries in both the ec and usa the reform of agricultural policy is likely to affect their trading and processing activities the aim of the paper is to discuss to what extent current reform coincides with or diverge from their interests three main issues are considered what are the effects of ec and usa traditional policies on multinationals how multinationals behave as a consequences of those agricultural policies and how the present reform could affect companies and induce restructuring process

bond yields and the federal reserve bond yields respond to policy decisions by the federal reserve and vice versa to learn about these responses i model a high frequency policy rule based on yield curve information and an arbitrage free bond market in continuous time the fed s target is a pure jump process jump intensities depend on the state of the economy and the meeting calendar of the federal open market committee the model has closed form solutions for yields as functions of a few state variables introducing monetary policy helps to match the whole yield curve because the target is an observable state variable that pins down its short end and introduces important seasonalities around fomc meetings the volatility of yields is snake shaped which the model explains with policy inertia the policy rule crucially depends on the two year yield and describes fed policy better than taylor rules

a direct discrete time approach to poisson gaussian bond option pricing in the heath jarrow morton model abstract term structure models employing poisson gaussian processes may be used to accommodate the observed skewness and kurtosis of interest rates this paper extends the discrete time pure gaussian version of the heath jarrow morton model to the pricing of american type bond options when the underlying term structure of interest rates follows a poisson gaussian process the poisson gaussian process is specified using a hexanomial tree six nodes emanating from each node and the tree is shown to be recombining the scheme is parsimonious and convergent this model extends the class of hjm models by i introducing a more generalized volatility specification than has been used so far and ii including jumps yet retaining lattice recombination thus making the model useful for practical applications

the implied jump risk of libor rates abstract this paper examines implied parameters from options on libor futures jump diffusion models are found to offer superior in sample and out of sample performance when compared to their pure diffusion counterpart the need to incorporate stochastic jump magnitudes into libor dynamics is also documented in addition empirical evidence reveals that the jump component in libor rates is important for pricing their derivatives furthermore variation in jump risk often coincides with federal open market committee fomc decisions and a small subset of macroeconomic announcements

valuation of american futures options theory and empirical tests this paper reviews the theory of futures option pricing and tests the valuation principles on transaction prices from the s p 500 equity futures option market the american futures option valuation equations are shown to generate mispricing errors which are systematically related to the degree the option is in the money and to the option s time to expiration the models are also shown to generate abnormal risk adjusted rates of return after transaction costs the joint hypothesis that the american futures option pricing models are correctly specified and that the s p 500 futures option market is efficient is refuted at least for the sample period january 28 1983 through december 30 1983 futures option contracts now trade on every major futures exchange and on a wide variety of underlying futures contracts the chicago mercantile exchange the chicago board of trade the new york futures exchange and the commodity exchange now collectively have more than twenty options written on futures contracts where the underlying spot commodities are financial assets such as stock portfolios bonds notes and eurodollars foreign currencies such as west german marks swiss francs and british pounds precious metals such as gold and silver livestock commodities such as cattle and hogs and agricultural commodities such as corn and soybeans moreover new contract applications are before the commodity futures trading commission and should be actively trading in the near future with the markets for these new contingent claims becoming increasingly active it is appropriate that the fundamentals of futures option valuation be reviewed and tested black 5 provides a framework for the analysis of commodity futures options although his work is explicitly directed at pricing european options on forward contracts it applies to european futures contracts as well if the riskless rate of interest is constant during the futures option life 1 the options currently

counterparty risk and the pricing of defaultable securities motivated by recent financial crises in east asia and the united states where the downfall of a small number of firms had an economy wide impact this paper generalizes existing reduced form models to include default intensities dependent on the default of a counterparty in this model firms have correlated defaults due not only to an exposure to common risk factors but also to firm specific risks that are termed counterparty risks numerical examples illustrate the effect of counterparty risk on the pricing of defaultable bonds and credit derivatives such as default swaps it has been well documented in moody s reports on historical default rates of corporate bond issuers that the number of defaults the number of credit rating downgrades and credit spreads are all strongly correlated with the business cycle this has motivated reduced form models such as duffie and singleton 1999 and lando 1994 1998 which assume that the intensity of default is a stochastic process that derives its randomness from a set of state variables such as the short term interest rate this approach has the convenient features that conditioning on the state variables defaults become independent events and default correlation arises due to the common inf luence of these state variables on the other hand a default intensity that depends linearly on a set of smoothly varying macroeconomic variables is unlikely to account for the clustering of defaults around an economic recession this is evident from a casual inspection of the exhibits in the latest moody s report see keenan 2000 within the usual affine framework one can model the state variables as jump diffusions see duffie pan and single

numerical evaluation of multivariate contingent claims we develop a numerical approximation method for valuing multivariate contingent claims the approach is based on an n dimensional extension of the lattice binomial method closed form solutions for the jump probabilities and the jump amplitudes are obtained the accuracy of the method is illustrated in the case of european options when there are three underlying assets article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

discrete time valuation of american options with stochastic interest rates we develop an arbitrage free discrete time model to price american style claims for which domestic term structure risk foreign term structure risk and currency risk are important this model combines a discrete version of the heath jarrow and morton 1992 term structure model with the binomial model of cox ross and rubinstein 1979 it converges weakly to the continuous time models in amin and jarrow 1991 1992 the general model is path dependent and can be implemented with arbitrary volatility functions to value claims with maturity up to five years the model is illustrated with applications to long dated american currency warrants and a cross rate swap from the quanto class article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

the performance of alternative interest rate risk measures and immunization strategies under a heath jarrow morton framework using a monte carlo simulation this study addresses the question of how traditional risk measures and immunization strategies perform when the term structure evolves in a heath jarrow morton 1992 manner the results suggest that for immunization purposes im munization strategies and portfolio formation strategies are more important than interest rate risk measures the performance of immunization strategies depends more on the transaction costs and the holding period than on the risk measures moreover the immu nization performance of bullet and barbell portfolios is not very sensitive to interest rate risk measures

vix option pricing and cboe vix term structure a new methodology for volatility derivatives valuation abstract this study integrates cboe vix term structure and vix futures to simplify vix option pricing in multifactor models exponential and hump volatility functions with one to three factor models of the vix evolution are used to examine their pricing for vix options across strikes and maturities the results show that using exponential volatility functions presents an effective choice as pricing models for vix calls whereas hump volatility functions provide efficient out of sample valuation for most vix puts in particular with deep in the money and deep out of the money pricing errors for calls can be further reduced with a two factor model

implied volatility functions in arbitrage free term structure models abstract we test six term structure models in the heath jarrow and morton 1992 class using eurodollar futures and options data from 1987 1992 we study the time series of implied interest rate volatilities from these models using one day lagged implied volatilities our one and two parameter models simultaneously price an average of 18 5 options each day with an average absolute error of one and a half to two basis points although the models fit well we document systematic strike price and time to maturity biases for all models we also implement simple trading strategies to test whether the models identify genuine biases

a bayesian approach to modeling stock return volatility for option valuation new measures of stock return volatility are developed to increase the precision of stock option price estimates with bayesian statistical methods volatility estimates for a given stock are developed using prior information on the cross sectional patterns in return volatil ities for groups of stocks sorted on size financial leverage and trading volume call option values computed with the bayesian procedure generally improve prediction accuracy for market prices of call options relative to those computed using implied volatility standard historical volatility or even the actual ex post volatility that occurred during each option s life although the bayesian methods produce biased call price estimators they do reduce the systematic tendency of standard pricing approaches to overprice underprice options on high low volatility stocks little bias improvement is observed with respect to the time to maturity and moneyness of the call options

valuation of american call options on dividend paying stocks empirical tests abstract this paper examines the pricing performance of the valuation equation for american call options on stocks with known dividends and compares it with two suggested approximation methods the approximation obtained by substituting the stock price net of the present value of the escrowed dividends into the black scholes model is shown to induce spurious correlation between prediction error and 1 the standard deviation of stock return 2 the degree to which the option is in the money or out of the money 3 the probability of early exercise 4 the time to expiration of the option and 5 the dividend yield of the stock a new method of examining option market efficiency is developed and tested

the systematic risk of discretely rebalanced option hedges this paper demonstrates that black scholes option pricing model hedge positions that are risk free when rebalanced continuously will frequently exhibit substantial systematic risk when rebalanced at finite intervals this systematic risk may have biased important empir ical tests of the option pricing model moreover this systematic risk means that the blackscholes option pricing model is inherently inconsistent with the discrete time version of the capital asset pricing model capm

pricing interest rate derivative securities this article shows that the one state variableinterest rate models of vasicek 1977 and cox ingersoll and ross 1985b can be extended sothat they are consistent with both the current termstructure of interest rates and either the currentvolatilities of all spot interest rates or the currentvolatilities of all forward interest rates theextended vasicek model is shown to be very tracta ble analytically the article compares option pricesobtained using the extended vasicek model withthose obtained using a number of other models
