meta paradigm change and the theory of the firm many seemingly unrelated debates on the theory of the firm are in fact part of a single deeper transformation of the social sciences as the foundational assumptions of 20th century social science have slowly been shown by science to be false new sub paradigms have emerged which cumulatively drop i theoretical assumptions about markets to explain firms ii epistemological assumptions about knowledge to explain diversity and iii metaphysical assumptions about causality to explain technical change debates occur across each of these levels

option valuation with systematic stochastic volatility we use an extension of the equilibrium framework of rubinstein 1976 and brennan 1979 to derive an option valuation formula when the stock return volatility is both stochastic and systematic our formula incorporates a stochastic volatility process as well as a stochastic interest rate process in the valuation of options if the mean volatility and covariance processes for the stock return and the consumption growth are predictable our option valuation formula can be written in preference free form further many popular option valuation formulae in the literature can be written as special cases of our general formula in this paper we investigate the valuation of individual stock options when the volatility of the underlying stock return is stochastic and has a systematic component which is related to the stochastic volatility of the consumption growth or the market return such an investigation is timely and of significant interest because there is now a considerable amount of evidence that the volatility of stock prices is not only stochastic but that it is also highly correlated with the volatility of the market as a whole for example see black 1975 conrad kaul and gultekin 1991 jarrow and rosenfeld 1984 jorion 1988 and ng engle and rothschild 1992 furthermore empirical work by black and scholes 1972 gultekin rogalski and tinic 1982 and whaley 1982 has shown that the empirical biases inherent in the black scholes option prices are different for options on high and low risk stocks because low risk stocks are mainly large firm stocks with stochastic return volatilities that are highly correlated with the return volatility of the market and high risk stocks are mainly small firm stocks with a lessimportant systematic volatility component incorporating systematic volatility effects in option valuation models has the potential to reduce the empirical biases exhibited by prices computed from the black scholes formula we use equilibrium arguments that extend the consumption based representative agent framework of rubinstein 1976 brennan 1979 and stapleton and subrahmanyam 1984 to allow individual asset returns and the consumption growth to exhibit stochastic volatility in particular we permit the volatility of individual asset returns to consist of a systematic component that is related to the consumption or market volatility in addi

does proportional representation foster closer congruence between citizens and policy makers this article assesses the claim that proportional representation pr fosters a closer correspondence between the views of citizens and the positions of the government the study uses the comparative study of electoral systems data set and compares respondents self placements on a left right scale with placements of cabinet parties locations in 31 election studies the authors argue that pr has two contradictory consequences on one hand pr leads to more parties and more choice for voters but these parties are less centrist and this increases the overall distance between voters and parties on the other hand pr increases the likelihood of coalition governments this pulls the government toward the center of the policy spectrum and reduces the distance between the government and voters these two contradictory effects of pr wash out and the net overall impact of pr on congruence is nil the data support the authors interpretation

the valuation of floating rate instruments abstract a framework for valuing floating rate notes is developed to examine the effects of 1 lags in the coupon formula 2 special contractual features and 3 default risk evidence from a sample of floaters indicates they sold at significant discounts while lags in the coupon formulas and other contractual features make these notes more variable they do not account for the magnitude of the discounts we conclude that the fixed default premium in the coupon formula of a typical note is inadequate to compensate for time varying default premiums demanded by investors who treat other corporate short term paper as close substitutes

the family and the state the immaturity of children sometimes precludes efficient arrangements between children and parents or others responsible for child care the difficulty in establishing efficient relations within families provides the point of departure for our interpretation of the heavy state involvement in the family the authors believe that a surprising number of state interventions mimic the agreements that would occur if children were capable of arranging for their care many regulations of the family improve the efficiency of family activities these interventions include subsidies to education and training social security and other old age support subsidies to births laws that limit access to divorce and the sale of children and laws that require parents permission for early marriage and other choices of children families that leave bequests can force children to repay parents for investments in human capital by reducing bequests therefore these families do not underinvest in childrens human capital by contrast families that do not leave bequests often poorer families do underinvest in children the state may subsidize schools and other training facilities to raise investments in children by poorer families to efficient levels authors modified

three problems of social organisation institutional law and economics meets habermasian law and democracy this paper attempts to identify certain implications of habermasian ethics for the economic analysis of law it does so by demonstrating a complementarity between the habermas of between facts and norms and the veblen ayres commons tradition s of economic analysis three unresolved problems of social organisation raised by the institutionalists are addressed the legitimacy of the status quo ante buchanan schmid the legitimacy of society s transaction structure klevorick and the problem of social order hobbes platteau discourse ethics demonstrates how these problems may be resolved the model of human agency adopted in institutional law and economics permits an easier fit with discourse ethics than would be possible with the neoclassical traditions

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

the law and economics movement in the last thirty years the scope of economics has expanded dramatically beyond its traditional domain of explicit market transactions today there is an economic theory of property rights of corporate and other organizations of government and politics of education of the family of crime and punishment of anthropology of history of information of racial and sexual discrimination of privacy even of the behavior of animals and overlapping all these but the last of law 2 some economists oppose this expansion in whole or more commonly in part 3 there are a number of bad reasons all i think closely related for such opposition and one slightly better one 1 one bad reason is the idea that economics means the study of markets so that nonmarket behavior is simply outside its scope this type of argument owes nothing really to economics but instead reflects a common misconception about language more specifically a failure to distinguish among three different types of word or concept the first type illustrated by the term marginal cost is purely conceptual the term is rigorously and unambiguously defined by reference to other concepts just as numbers are but again like numbers there is no observable object in the real world that it names try finding a firm s marginal costs on its books of account the second type of word illustrated by rabbit refers to a set of real world objects few such words are purely referential one can speak of a pink rabbit or a rabbit the size of a man without misusing the word even though one is no longer using it to describe anything that exists nevertheless the referential function dominates finally there are words like law religion literature and economics which are neither conceptual nor referential such words resist all efforts at definition they have in fact no fixed meaning and their dictionary definitions are circular they can be used but not defined 4 one cannot say that economics is what economists do because many noneconomists do economics one cannot call economics the science of rational choice either the word rational lacks a clear definition and passing that difficulty there can be noneconomic theories of rational choice in which few predictions of ordinary economics may hold for example because the theory assumes that people s preferences are unstable there can also be nonrational economic theories an example is the type of survival theory in industrial organization in which firms that randomly hit on methods of lowering their costs expand vis a vis their rivals another example is marxism one cannot call economics the study of markets either not only because that characterization resolves the question of the domain of eco judge u s court of appeals for the seventh circuit senior lecturer university of chicago law school 1111 e 60th st chicago il 60637 i thank gary becker frank easterbrook william landes geoffrey miller richard porter george stigler geoffrey stone and alan sykes for comments on a previous draft and nir yarden for research assistance see for example gary becker 1976 jack hirshleifer 1985 p 53 george stigler 1984 gerard radnitzky and peter bernholz 1986 2 for a recent conspectus of economic analysis of law see my book 1986 3see for example ronald coase 1978 coase is of course a leading figure in the economics of property rights so his opposition is far from total 4for an excellent discussion see john ellis 1974 ch 2

the valuation of american options on bonds abstract we value american options on bonds using a generalization of the geske johnson geske r johnson h 1984 journal of finance 39 1151 1542 gj technique the method requires the valuation of european options and options with multiple exercise dates it is shown that a risk neutral valuation relationship rnvr along the lines of black scholes black f scholes m 1973 journal of political economy 81 637 659 model holds for options exercisable on multiple dates even under stochastic interest rates when the price of the underlying asset is lognormally distributed the proposed computational procedure uses the maximized value of these options where the maximization is over all possible exercise dates the value of the american option is then computed by richardson extrapolation the volatility of the underlying default free bond is modeled using a two factor model with a short term and a long term interest rate factor we report the results of simulations of american option values using our method and show how they vary with the key parameter inputs such as the maturity of the bond its volatility and the option strike price

thorstein veblen and post darwinian economics thorstein veblen is noted for his view that economics should be an evolutionary science however although the term evolutionary has been adopted in general terms by subsequent institutional economists there has been remarkably little detailed exploration informed by biology of what veblen meant by an evolutionary science and the character of the post darwinian economics that he attempted to build this essay explores the reasons for veblen s attachment to darwinism informed by developments in biology itself and identifies some distinctive and enduring features of veblen s evolutionary theory copyright 1992 by oxford university press

a directional theory of issue voting from stokes s 1963 early critique on it has been clear to empirical researchers that the traditional spatial theory of elections is seriously flawed yet fully a quarter century later that theory remains the dominant paradigm for understanding mass elite linkage in politics we present an alternative spatial theory of elections that we argue has greater empirical verisimilitude based on the ideas of symbolic politics the directional theory assumes that most people have a diffuse preference for a certain direction of policy making and that people vary in the intensity with which they hold those preferences we test the two competing theories at the individual level with national election study data and find the directional theory more strongly supported than the traditional spatial theory we then develop the implications of the directional theory for candidate behavior and assess the predictions in light of evidence from the u s congress

the determinants of asymmetric volatility volatility in equity markets is asymmetric contemporaneous return and conditional return volatility are negatively correlated in this article i develop an asymmetric volatility model where dividend growth and dividend volatility are the two state variables of the economy the model allows both the leverage effect and the volatility feedback effect the two popular explanations of asymmetry the model is estimated by the simulated method of moments i find that both the leverage effect and volatility feedback are important determinants of asymmetric volatility and volatility feedback is significant both statistically and economically the relationship between stock price and its volatility has long interested financial researchers empirically returns and conditional variance of next period s returns are negatively correlated that is negative positive returns are generally associated with upward downward revisions of the conditional volatility this empirical phenomenon is often referred to as asymmetric volatility in the literature see engle and ng 1993 zakoian 1994 and wu and xiao 1999 the presence of asymmetric volatility is most apparent during stock market crashes when a large decline in stock price is associated with a significant increase in market volatility formal econometric models have been developed by researchers to capture asymmetric volatility for example asymmetric arch models of nelson 1991 and glosten jagannathan and runkle 1993 have been found to significantly outperform their counterparts that do not accommodate the asymmetry moreover continuous time stochastic volatility models generally produce estimates of a negative correlation between return and return volatility bakshi cao and chen 1997 and bates 1997 for a review of the literature on asymmetric volatility see bekaert

an alternative valuation model for contingent claims abstract this paper studies contingent claim valuation in a lucas type exchange economy the derived fundamental valuation equation differs from its cox ingersoll ross production economy counterpart in that it is expressed in terms of the direct utility function and an exogenous output process thus offering superior tractability we apply our approach to derive closed form solutions for bond bond option individual stock and stock option prices under a more general setting than allowable in the cox ingersoll ross framework the resulting interest rate and stock price dynamics are empirically plausible moreover our stock option pricing formula with stochastic volatility and interest rates can reconcile certain puzzling empirical regularities including the volatility smile

breaking the mould an institutionalist political economy alternative to the neo liberal theory of the market and the state the paper criticises the currently dominant neo liberal discourse on the role of the state and proposes an alternative approach that will allow us to overcome its shortcomings especially its inadequate analyses of the role of institutions and politics it argues that the central problem with the neo liberal framework lies not in its excessively anti interventionist policy conclusions as some of its critics believe but in the very ways it envisages the modus operandi of the market the state institutions and their interrelationships the paper then discusses how we may construct the alternative approach of institutionalist political economy

a pedagogical treatment of bilateral monopoly most economists are familiar with the concept of bilateral monopoly an upstream monopolist sells its output to a single downstream buyer that may also be a monopolist in its output market the theory of bilateral monopoly has a rich history that can be traced to the writings of cournot 10 and menger 31 over the 150 or so years that the problem has been under consideration however economists have offered a variety of solutions ranging from a completely determinate intermediate good price and output to a completely indeterminate solution within a specified range interestingly this historical divergence of opinion concerning the correct outcome under bilateral monopoly still persists a clear consensus has not yet emerged surprisingly this lack of unanimity exists despite the fact that bowley 5 provided the theoretically correct solution in 1928 2 even more surprising however is the apparent popularity of the incorrect solution a recent survey of the population of intermediate microeconomic texts on the authors bookshelves revealed that over 80 percent of the current treatments of this topic are in error 3 table i presents the results of that survey those authors who present a correct analysis of bilateral monopoly recognize that optimality requires joint profit maximization this leads them to the correct conclusion regarding the determinate quantity of the intermediate product exchanged of the five treatments we have classified

veblen s evolutionary programme a promise unfulfilled this article examines in detail the way in which veblen attempted to give theoretical expression to the programme for an evolutionary economics that he outlined in methodological terms in his 1898 essay why is economics not an evolutionary science veblen s conception of darwinian methodological principles led him to attempt to develop a theory of institutional evolution that was purely causal in nature this theory was never satisfactorily developed by veblen at base his theory was one of new technology changing economic conditions and new economic conditions leading to new ways of thinking and to new institutions through a non intentional process of habituation those who attempted to follow veblen such as hoxie and mitchell found difficulties with the key aspects of this theory and both men came to abandon it institutionalism in the interwar period is devoid of attempts to develop veblen s theory and veblen s programme remained a promise unfulfilled

pricing foreign currency options under stochastic interest rates abstract in this paper we build a general framework to price contingent claims on foreign currencies using the heath et al 1987 model of the term structure closed form solutions are obtained for european options on currencies and currency futures assuming that the volatility functions determining the term structure are deterministic as such this paper provides an example of a bond price process for both the domestic and foreign economies consistent with grabbe s 1983 formulation of the same problem

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

the source of optimality in action it is well known that the nature of the information set and the axioms of rational choice are critical in determining the type of ranking on which agents are held to act in economic theory this paper argues that the concept of the optimising agent is also sensitive to the conception of the relation between a ranking of options facing an agent and concrete action what is termed the realisation process three conceptions of the realisation process are examined which are seen to lead to three quite distinct views on the role of agency the enabling conditions under which the concept of the optimising agent may be legitimately applied and the resulting domain of application of optimisation

forward contracts and futures contracts abstract this paper provides a detailed discussion of the similarities and differences between forward contracts and futures contracts under frictionless markets and continuous trading simple arbitrage arguments are invoked to value forward contracts to relate forward prices and spot prices and to relate forward prices and futures prices we also argue that forward prices need not equal futures prices unless default free interest rates are deterministic

the analysis and valuation of interest rate options abstract this paper provides a simple alternative model for the valuation of european style interest rate options the assumption that drives the hedging argument in the model is that the forward prices of bonds follow an arbitrary two state process later this assumption is made more specific by postulating that the discount on a zero coupon bond follows a multiplicative binomial process in contrast to the black scholes assumption applied to zero coupon bonds the limiting distribution of this process has the attractive features that the zero bond price has a natural barrier at unity thus precluding negative interest rates and that the bond price is negatively skewed the model is used to price interest rate options in general and interest rate caps and floors in particular the model is then generalized and applied to european style options on bonds a relationship is established between options on swaps and options on coupon bonds the generalized model then provides a computationally simple formula closely related to the black scholes formula for the valuation of european style options on swaps

appropriation violent enforcement and transaction costs a critical survey this paper focuses on the extension of transaction costs to appropriative activity and coercive power in the property rights approach it has been argued that including the costs of appropriation and violent enforcement in transaction costs is based on the assumption that coaseian bargaining can be extended to any institutional scenario i e voluntary as well as coercive exchange however voluntary transactions cannot capture the logic of coercive power this means that the assumption of an efficient political market is not valid and that the political coase theorem lacks the logical consistency to provide a cornerstone for political theory

a path dependent approach to security valuation with application to interest rate contingent claims abstract the last two decades have witnessed a tremendous growth in the volume of assets and liabilities whose cash flows depend in a variety of ways on the path of interest rates some of these including floating rate notes and swap agreements contractually base cash flows on current and past interest rates and contain caps floors and other more complex features others including mortgages many corporate bonds and time deposits are fixed rate instruments that contain embedded options such as those to prepay call or withdrawal the irregular exercise of these options causes cash flows to vary as time proceeds and interest rates rise or fall this paper develops a state contingent claims technique for valuing such securities it is derived from the option based model of breeden and litzenberger 1978 using the transition matrix approach of banz and miller 1978 particular attention is paid to valuing so called path dependent securities whose contemporaneous cash flows depend on the historical path of interest rates as well as their current level a detailed example is provided in which an adjustable rate mortgage is valued under a variety of economic and security specific assumptions

exchange rate uncertainty and us bilateral fresh fruit and fresh vegetable trade an application of the gravity model in order to analyse the effect of exchange rate uncertainty we apply an empirical gravity equation to two sets of us bilateral trade data fresh fruit over the period 1976 1999 for a panel of 26 countries and fresh vegetables over the period 1976 2006 for a panel of nine countries based on panel estimation methods and using both a moving sd measure and the peree and steinherr 1989 measure of exchange rate uncertainty the results show that us bilateral fresh fruit trade has been negatively affected by exchange rate uncertainty we also find some evidence that the exchange rate between the us dollar and the currencies of latin american trading partners accounts for most of the negative impact of exchange rate uncertainty on bilateral trade flows in fresh fruit in contrast when using panel estimation methods and both measures of exchange rate uncertainty we find no statistically significant evidence for any negative effect of exchange rate uncertainty on us bilateral fresh vegetable trade however

stochastic volatility movements in short term interest rates and bond option values abstract two classes of models for pricing interest rate contingent claims are compared the first contains standard single factor models while the second includes stochastic volatility variants of these it is demonstrated that incorporating stochastic volatility significantly improves the ability of the models to fit movements in short term interest rates the fundamental reason for this is that standard univariate models do not generate enough conditional heteroskedasticity the models are also compared on the basis of bond option prices when each is constrained to fit a particular yield curve the results suggest that stochastic volatility models will typically produce lower option values than corresponding single factor models particularly for near the money to deep out of the money options this is because estimated historical volatilities are significantly lower under stochastic volatility when single factor models are constrained to the same level of volatility as implied by stochastic volatility models in most cases the pricing differences become minor

fixed income linked life insurance policies with minimum guarantees pricing models and numerical results abstract we propose a pricing model for life insurance policies in which the benefits are linked to the performance of a portfolio of interest rate sensitive assets reference fund and a minimum guarantee provision is present the model is cast in the celebrated term structure framework developed by cox ingersoll and ross 1985 as for the behaviour of the investment component we analyse two polar cases in the first one the payments due on the reference fund when the contract is still alive are not reinvested while in the second case we propose a reinvestment policy we show how to obtain a closed form solution for the single premium in the no reinvestment case and how to implement a simulation approach to calculate numerically the single premium in the reinvestment case we illustrate our analysis with numerical results that help in understanding the comparative static properties of the models proposed

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

religious freedom and the unintended consequences of state religion 1 introduction a union of government and religion tends to destroy government and degrade religion so wrote justice hugo black in the majority opinion in engel v vitale 1 a 1962 school prayer case decided by the united states supreme court today church state issues continue to rise to the forefront of american politics in recent years alone disputes have arisen over public school vouchers and prayers the phrase under god in the pledge of allegiance the display of the ten commandments in public meeting halls and courthouses and the proper scope of president bush s recent faith based and community initiative across the atlantic william carey the recently retired archbishop of canterbury argued in april 2002 that establishment strengthens the church of england by allowing it to build a comprehensive network of parishes throughout the entire country and he denied that establishment has constrained the prophetic voice of the church 2 in contrast carey s successor rowan williams who became archbishop of canterbury in july 2002 has in the past advocated the disestablishment of the church of england 3 in sweden where the church of sweden had been the state church since 1593 the parliament passed a statute providing for the formal disestablishment of the church on january 1 2000 4in the united states the strongest advocates for giving religion a more prominent role in governmental settings have often been religious conservatives whereas the strongest opponents are often political liberals for example in the recently decided cleveland school voucher case 5 christian organizations like focus on the family the christian legal society the ethics and religious liberty commission of the southern baptist convention the national association of evangelicals and the united states conference of catholic bishops filed briefs in support of the program which allowed public funds to pay tuition in private schools including religious schools among the organizations filing briefs in opposition to the program were the naacp and various public education lobbies whereas the american civil liberties union people for the american way and americans united for separation of church and state provided legal representation for some of the plaintiffs challenging the voucher program interestingly however several religious organizations also filed briefs in opposition to the voucher program including the american jewish committee the jewish council for public affairs the baptist joint committee on public affairs the national council of churches of christ in the usa ncc and two regional seventh day adventist organizations except for the ncc these organizations represent the interests of religious groups that are or in the case of the baptists once were distinctly in the religious minority a growing body of research suggests that any positive benefits to the church with direct support from the state are outweighed by indirect effects that undermine the church s autonomy and its authority with the general populace for an excellent introduction to this research see stark and finke 2000 chapter 9 if such research is correct then the advocates of governmental endorsement of religion may be undermining the very institutions they seek to support in this article we use cross country survey responses to assess the impact of religious freedom and the separation of church and state on the health of religion throughout the world using survey responses on the frequency of attendance at religious services we find that government establishment of state religion reduces religious attendance whereas enduring constitutional protection of religion increases religious attendance adam smith recognized that establishment could ultimately undermine the state religion in the wealth of nations smith discussed the impact of establishing a religion on the fervor and effectiveness of the clergy in that religion the teachers of religion in the same manner as other teachers may either depend altogether for their subsistence upon the voluntary contributions of their hearers or they may derive it from some other fund to which the law of their country may entitle them such as a landed estate a tythe or land tax an established salary or stipend

pricing contingent claims under interest rate and asset price risk this paper presents a general framework for pricing contingent claims under interest rate and asset price uncertainty the framework extends ho and lee s 1986 valuation framework by allowing not only future interest rates but also future asset prices to depend on the current term structure of interest rates the approach is shown to provide risk neutral valuation relationships that are consistent with the initial term structure of interest rates and can be applied to valuation of a broad class of assets including stock options convertible bonds and junk bonds

information and the coase theorem abstract some economists think the coase theorem implies a lot about the proper scope of government intervention in the economy and about the welfare consequences of laissez faire others see it as a mere tautology that if people negotiate efficiently then every outcome will be efficient the coase theorem is important only if we believe that efficient negotiation is likely of course we can attribute inefficiencies to bargaining imperfection but it may not be useful to do so such attitudes sometimes seem to depend more on ideology than on reason this article gives one economist s reasoned view it discusses the coase theorem as a decentralization result and why decentralization results are interesting it considers mechanism design for revealing private information and describes the problems of centralization should the coase theorem should be viewed as a second best result property rights are more efficient than some reasonable alternative does the coase theorem recommend an institution or make

a theory of competition among pressure groups for political influence this paper presents a theory of competition among pressure groups for political influence political equilibrium depends on the efficiency of each group in producing pressure the effect of additional pressure on their influence the number of persons in different groups and the deadweight cost of taxes and subsidies an increase in deadweight costs discourages pressure by subsidized groups and encourages pressure by taxpayers this analysis unifies the view that governments correct market failures with the view that they favor the politically powerful both are produced by the competition for political favors

the competence based approach veblenian ideas in the modern theory of the firm the author argues that a contemporary stronghold of a number of thorstein veblen s crucial ideas can be found in the emerging competence based approach to the firm e g penrose chandler winter for example the emphasis in this literature on firms as path dependent entities characterized by their heterogenous and group based knowledge bases can be linked with key themes in veblen s work thus the paper presents the competence based approach as a modern veblenian approach moreover the veblenian aspects of the competence based approach are also those aspects that most differentiate it from the other dominant economic approach to the firm the contractual approach e g alchian and demsetz williamson grossman and hart the aim of the paper is both to make this historical point and to present a contemporary body of theory that may with some justice be called veblenian copyright 1998 by oxford university press

the relation between forward prices and futures prices abstract this paper consolidates the results of some recent work on the relation between forward prices and futures prices it develops a number of propositions characterizing the two prices these propositions contain several testable implications about the difference between forward and futures prices many of the propositions show that equilibrium forward and futures prices are equal to the values of particular assets even though they are not in themselves asset prices the paper then illustrates these results in the context of two valuation models and discusses the effects of taxes and other institutional factors

pricing interest rate options in a two factor cox ingersoll ross model of the term structure solutions are presented for prices on interest rate options in a two factor version of the cox ingersoll ross model of the term structure specific solutions are developed for caps on floating interest rates and for european options on discount bonds coupon bonds coupon bond futures and euro dollar futures the solutions for the options are expressed as multivariate integrals and we show how to reduce the calculations to univariate numerical integrations which can be calculated very quickly the two factor model provides more flexibility in fitting observed term structures and the fixed parameters of the model can be set to capture the variability of the term structure over time 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

taxes institutions and innovation theory and international evidence we develop an international model of the design of institutions for regulating innovative activities of private corporations informational limitations faced by the social planner preclude complete contracting with private firms corporate innovation creates positive and negative externalities the social planner in each country takes into account the legal system in place and designs an umbrella of institutions that include a menu of organizational forms liability structures corporate taxes and subsidies we show that limited liability may be accompanied by excessive innovation however when the nonmonetized benefits are very high private firms may be too conservative in innovation policies firms choose their organizational form and level of innovation consistent with private optimality with the optimal institutional design for each country we demonstrate that private innovation choices are aligned with social optimality in particular we show that the optimally designed corporate tax rate in each country is a decreasing function of its legal effectiveness using data from 63 countries over 2003 2018 we document supporting evidence mncs can take advantage of differential liability and corporate tax structures across national boundaries to circumvent institutional design constraints however when mncs generate positive externalities to host countries their governments may provide subsidies and incentives

the new institutional economics and the theory of behaviour under uncertainty the new institutional economics nie is diverse in terms of the theory of behaviour under uncertainty some views are close to neoclassical economics but others are similar to those held by heterodox economists distinctions between procedural and substantive uncertainty weak and strong uncertainty and ambiguity and fundamental uncertainty help to identify different approaches to uncertainty in nie regarding the influence of institutions on economics behaviour not all nie focuses on institutions as constraints and takes individuals as given the dominant views of rationality in nie are standard neoclassical maximization and bounded rationality but alternative notions have also been defended

real and nominal interest rates a discrete time model and its continuous time limit i provide a general equilibrium theory of the term structure of real interest rates in a discrete time economy i derive the prices for one period and two period real bonds and a simple recursive formula for general k period bonds and prove that the price formula with appropriately specified parameters converges to that of the cox ingersoll and ross model 1985 in addition i consider the behavior of nominal bond prices in a partial equilibrium setting in which an exogenous price level process is correlated with the real economy finally i provide an illustrative empirical investigation of the model the results indicate a significant correlation between the price level and the growth rate of consumption which does not support the money nuetrality assumption underlying cox ingersoll and ross s nominal bond prices and related empirical studies such as gibbons and ramaswamyu 1992 heston 1991 and pearson and sun 1991 article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

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
