a theory of commerce abstract the theory of commerce advanced here captures prominent features of retail trade large employment congestion effects anonymous posted prices and quantity discounts this theory is built around a directed search model where buyers preferences are private information the analytical solution is easily inserted in a neoclassical growth framework in this framework the parameters of retail trade are calibrated using commercial margins and employment welfare properties depend on the sellers ability to charge two tier prices with two tier prices the directed search equilibrium is efficient otherwise it is not this contrasts with the full information benchmark where directed search is always efficient

the inflation tax in a real business cycle model money is incorporated into a real business cycle model using a cash in advance constraint the model economy is used to analyze whether the business cycle is different in high inflation and low inflation economies and to analyze the impact of variability in the growth rate of money in addition the welfare cost of the inflation tax is measured and the steady state properties of high and low inflation economies are compared

an equilibrium debt option pricing model in discrete time abstract in this paper we develop a discrete time binomial model for pricing options on default free debt securities the model is a single factor or spot rate model in which an arbitrage free term structure is developed and used to price any interest rate contingent claim the model differs from other work in this area in that the model is straightforward to program and use and is not bound by a restrictive equilibrium concept such as the expectations hypothesis the paper demonstrates various properties of the model and demonstrates how information from the existing term structure can be used to parameterize the model

precautionary demand for money in a monetary business cycle model we investigate the quantitative implications of precautionary demand for money for business cycle dynamics of velocity of money and other nominal aggregates there is a standing challenge in monetary macroeconomics to account for business cycle dynamics of nominal variables as previous business cycle models that have tried to incorporate demand for money have failed to generate realistic predictions in this regard our stance is that part of this failure results from the fact that demand for money in those previous models is deterministic since agents in them face only aggregate risk whereas we believe idiosyncratic risk to be important as well we conduct the exercise inside a monetary search model as our additional goal is to put to the test a recent generation of such frictional models to examine whether their quantitative predictions are realistic and whether they generate additional insight into business cycle data that non search models of money cannot generate on the first question our results suggest that precautionary demand for money plays a substantial role in accounting for business cycle behavior of velocity of money and other nominal variables such as inflation and nominal interest rates on the second question our preliminary results indicate that the search frictions generate discernible though small quantitative effects helping the model account for relevant properties of the data but not very significantly the biggest quantitative potential for search frictions in this setting is in the dynamic implications they generate for inventories and markups in the retail sector assessment of this potential is in progress

the valuation of options on yields abstract many contingent claims incorporate options on yield levels i derive closed form expressions for european yield option prices using a general equilibrium model in which the underlying yield is the relevant state variable the properties of these options differ markedly from those of conventional options on traded assets for example yield call values can be less than their intrinsic value and can be decreasing functions of the underlying yield these features have important hedging implications i examine the empirical implications of the model using price data for the 13 week t bill options traded on the chicago board options exchange

interest rate volatility and the term structure a two factor general equilibrium model we develop a two factor general equilibrium model of the term structure the factors are the short term interest rate and the volatility of the short term interest rate we derive closed form expressions for discount bonds and study the properties of the term structure implied by the model the dependence of yields on volatility allows the model to capture many observed properties of the term structure we also derive closed form expressions for discount bond options we use hansen s generalized method of moments framework to test the cross sectional restrictions imposed by the model the tests support the two factor model there are essentially two approaches to the modeling of the term structure of interest rates in continuous time the equilibrium approach pioneered by

inflation and welfare in a monetary economy it is in everyone s private interest to try to get someone else to hold non interest bearing cash and reserves but someone has to hold it all so these efforts must simply cancel out all of us spend several hours per year in this effort and employ thousands of talented and highly trained people to help us these person hours are simply thrown away wasted on a task that should not have to be performed at all

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 equilibrium model of bond pricing and a test of market efficiency in two previous and related papers 3 4 the authors have reported the results of estimating a particular equilibrium model of bond pricing using quarterly data on canadian government bonds for the period 1964 to 1979 this paper reports the results of applying a similar model to the pricing of u s government bonds for the period 1958 1979 using data from the crsp government bond file the paper also extends the previous empirical analysis by evaluating the ability of the pricing model to detect underpriced and overpriced bonds the data reveal a strong relation between price prediction errors and subsequent bond returns

syndicated loan announcements and the the market value of the banking firm this paper examines valuation effects on the stocks of fifteen participating money center banks of 774 announcements of syndicated loans representing announcements of investment decisions for the lenders the authors find that announcements of ldc loans in the 1970s especially those to latin american borrowers are associated with negative abnormal returns to the lending banks while announcements of loans to u s corporate borrowers in the 1980s especially those for takover finance are associated with positive abnormal returns while a number of testable predictions are consistent with the negative abnormal returns for latin american loans they explain response to takeover loans with a return to liquidity hypothesis copyright 1995 by ohio state university press

financial innovation and the transactions demand for cash we document cash management patterns for households that are at odds with the predictions of deterministic inventory models that abstract from precautionary motives we extend the baumol tobin cash inventory model to a dynamic environment that allows for the possibility of withdrawing cash at random times at a low cost this modification introduces a precautionary motive for holding cash and naturally captures developments in withdrawal technology such as the increasing diffusion of bank branches and atm terminals we characterize the solution of the model which qualitatively reproduces several empirical patterns we estimate the structural parameters using micro data and show that quantitatively the model captures important economic patterns the estimates are used to quantify the expenditure and interest rate elasticity of money demand the impact of financial innovation on money demand the welfare cost of inflation and the benefit of atm ownership

bank foreign lending mandatory disclosure rules and the reaction of bank stock prices to the mexican debt crisis this paper examines the effects of the mexican debt mora torium in august 1982 on bank valuation the mexican default resulted in the passage of regulations requiring public disclosure of bank fo reign lending exposure the authors find that even in the absence of public disclosure regulations investors were able to discriminate a mong banks with different levels of exposure copyright 1987 by the university of chicago

bank portfolio exposure to emerging markets and its effects on bank market value abstract this study estimates a model of banking company equity returns taking into consideration book value and market value measures of their exposure to emerging markets debt in this estimation general systematic market factors such as the rate of return on the s p500 stock index and yields on a constant maturity 5 year treasury note are held constant such that the exposure variables are accounting for effects due to banks exposure to emerging market debt the results although not uniform among banking companies support the hypothesis that the extent of exposure to emerging market debt are factored into the valuation of banking company equity contemporaneously the inclusion of a market value indicator adds to the explanation of equity returns of some banks it is also clear that knowing the extent of the exposure on a book value basis is important information alone that may allow investors to take account of or evaluate the effects of changes in banking company equity valuation from ldc debt exposures we also perform an event study for three major debt crises to determine whether the market recognizes the effects of these events on bank valuation the event study results show that there is little information from identifying the time period of the crises on banking company equity returns explanations for this are that the information of these possible crises has been embedded in bank changes in exposure and that the market valuation of the emerging market debt is already accounted for by our model

inflation output and welfare this paper studies the effects of anticipated inflation on aggregate output and welfare within a search theoretic framework we allow money holders to choose the intensities with which they search for trading partners so inflation affects the frequency of trade as well as the quantity of output produced in each trade we consider the standard pricing mechanism for search models i e ex post bargaining as well as a notion of competitive pricing if prices are bargained over the equilibrium is generically inefficient and an increase in inflation reduces buyers search intensities output and welfare if prices are posted and buyers can direct their search search intensities are increasing with inflation for low inflation rates and decreasing for high inflation rates the friedman rule achieves the first best allocation and inflation always reduces welfare even though it can have a positive effect on output for low inflation rates

a divisible search model of fiat money this paper extends the kiyotaki wright search model of fiat money to allow for divisible money and goods the extension allows me to examine the standard issues in monetary economics such as the neutrality and superneutrality of money by severing the artificial link in the kiyotaki wright model between the money supply and the number of money holders it is shown that money is neutral but not superneutral money growth generates a trading opportunity effect it changes the fraction of different agents in the economy and hence changes the probability with which agents have a successful match in addition money growth has a negative effect on the real money balance that is familiar in walrasian monetary models the balance of the two effects can imply a positive optimal money growth rate

friction in the trading process and the estimation of systematic risk abstract this paper considers how estimates of the market model beta parameter can be biased by friction in the trading process information decision and transaction costs that a leads to a distinction between observed and true returns b causes observed returns to be generated asynchronously for a set of interdependent securities and c thereby introduces serial cross correlation into security returns several propositions are derived from which consistent estimators of beta are obtained and the effect of differencing interval length on beta estimates is specified the formulation is contrasted with the related analyses of scholes williams 1977 and dimson 1979

an empirical examination of the pricing of european bond options abstract this paper examines the pricing of european bond options namely options on a five year swedish t bond a continuous time version of the ho and lee model derived by heath jarrow and morton and the black and scholes model are tested using hansen s generalized method of moments the results indicate that both models perform reasonably well however the black and scholes model exhibits a time to maturity of the bond bias not present in the heath jarrow and morton model

precautionary balances and the velocity of circulation of money the observed low velocity of circulation of money implies that households hold more money than they normally spend a natural explanation for this behavior is that households face uncertain expenditure needs so they have a precautionary motive for holding money we investigate the precautionary demand for money in a search model where households are subject to preference shocks the model predicts that the velocity of circulation of money is not only low but also interest elastic the model closely fits united states data on the velocity of circulation of money and interest rates that span the period 1892 2003 the empirical analysis reveals a dramatic reduction in precautionary balances towards the end of our sample probably linked to innovations in the information technology this drop in precautionary balances is crucial for important issues of monetary economics such as the elasticity of the demand for money and the welfare cost of inflation

whither monetary economics i argue that monetary economics should be pursued by applying implementation theory to models which contain explicit frictions that make money essential the argument has two parts first i argue that models in which real balances are assumed to be productive models with money in utility or production functions or with cash in advance constraints contain hidden inconsistencies second i argue that the approach advocated is capable of providing new insights about some of the main issues in monetary economics the effects of monetary shocks the welfare cost of inflation and the roles of inside and outside money

money in search equilibrium in competitive equilibrium and in competitive search equilibrium we compare three market structures for monetary economies bargaining search equilibrium price taking competitive equilibrium and price posting competitive search equilibrium we also extend work on the microfoundations of money by allowing a general matching technology and entry we study how equilibrium and the effects of policy depend on market structure under bargaining trade and entry are both inefficient and inflation implies first order welfare losses under price taking the friedman rule solves the first inefficiency but not the second and inflation may actually improve welfare under posting the friedman rule yields the first best and inflation implies second order welfare losses

financial innovations money demand and the welfare cost of inflation in the 1990s the empirical relation between money demand and interest rates began to fall apart we analyze to what extent improved access to money markets can explain this break down for this purpose we construct a microfounded monetary model with a money market which provides insurance against liquidity shocks by offering short term loans and by paying interest on money market deposits we calibrate the model to u s data and find that improved access to money markets can explain the behavior of money demand very well furthermore we show that by allocating money more efficiently better access to money markets decrease the welfare cost of inflation substantially

money liquidity and welfare abstract this paper develops an analytically tractable bewley model of money demand to shed light on some important questions in monetary theory such as the welfare cost of inflation it is shown that when money is a vital form of liquidity to meet uncertain consumption needs the welfare costs of inflation can be extremely large with log utility and parameter values that best match both the aggregate money demand curve suggested by lucas 2000 and the variance of household consumption agents in our model are willing to reduce consumption by 3 4 to avoid 10 annual inflation the astonishingly large welfare costs of inflation arise because inflation increases consumption risk by eroding the buffer stock insurance value of money thus hindering consumption smoothing at the household level such an inflation induced increase in consumption risk at the micro level cannot be captured by representative agent models or the bailey triangle although the development of financial intermediation can mitigate the problem with realistic credit limits the welfare loss of moderate inflation still remains several times larger than estimations based on the bailey triangle our findings provide a strong justification for adopting a low inflation target by central banks especially in developing countries where money is the major form of household financial wealth

simple binomial processes as diffusion approximations in financial models a binomial approximation to a diffusion is defined as computationally simple if the number of nodes grows at most linearly in the number of time intervals it is shown how to construct computationally simple binomial processes that converge weakly to commonly employed diffusions in financial models the convergence of the sequence of bond and european option prices from these processes to the corresponding values in the diffusion limit is also demonstrated numerical examples from the constant elasticity of variance stock price and the cox ingersoll and ross 1985 discount bond price are provided article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

a note on an interest rate immunization strategy abstract the mechanisms for insuring investments in stocks and bonds against depreciation have grown rapidly in the last decade insuring a portfolio entails managing it in such a way that the left hand tail of the return distribution is truncated the present paper demonstrates how this may be achieved for fixed interest securities discrete time hedging procedures are derived with the inclusion of transaction costs

a model of money and credit with application to the credit card debt puzzle many individuals simultaneously have significant credit card debt and money in the bank the credit card debt puzzle is given high interest rates on credit cards and low rates on bank accounts why not pay down the debt while economists have gone to elaborate lengths to explain this observation we argue it is a special case of the rate of return dominance puzzle from monetary economics we analyze the issue by extending standard monetary theory to incorporate consumer debt this seems interesting in its own right since developing models where money and credit coexist is a long standing challenge and it helps put into context recent discussions of consumer debt

lack of recall and centralized monetary trade we introduce lack of recall of past transactions as an alternative assumption to anonymity in a model where trade is centralized in environments where there is an intertemporal lack of double coincidence of wants problem and lack ofcommitment lack of recall can give rise to monetary equilibria that dominate nonmonetary outcomes in terms of welfare

search for a monetary propagation mechanism abstract this paper examines a monetary propagation mechanism in an economy where exchanges in goods and labor markets involve costly search it is shown that an increase in the money growth rate increases steady state employment and output when the money growth rate is low but reduces steady state employment and output when the money growth rate is already high the model produces persistent hump shaped responses in employment and output to money growth shocks even when the shocks have no persistence the model also generates desirable features in job vacancy sales inventory and the velocity of money all these features emerge here in an economy with perfectly flexible prices and wages journal of economic literatureclassification numbers e40 e30

on the relation between reschedulings and bank value the effect of developing country loan reschedulings on large u s banks is investigated using an event study methodology the major finding concerns the evolving nature of the impact of loan reschedulings during 1978 80 reschedulings had a positive effect on bank returns in contrast to the negative impact found for the 1981 83 period an explanation for these results is provided by a model of the rescheduling process that recognizes the noncompetitive aspects of rescheduling negotiation copyright 1989 by american economic association

the impact of sovereign risk on the market valuation of u s bank equities abstract this paper tests whether the august 1982 advent of the latin american debt crisis affected the implicit value of commercial bank loans to major latin american debtors and hence the value of equities in contrast to previous studies the analysis provides an explicit derivation of the theoretical impact of such an effect uses a more efficient pooled cross sectional time series estimating technique addresses the question of whether ex ante required returns on bank equities also were affected and compares the estimates to the behavior of the direct market for latin american bonds the results imply that the crisis did cause significant debt discounting as well as an increase in required returns however unlike the bond market most of this equity effect was delayed 6 9 months

money and asset prices in a cash in advance economy an asset pricing model with money introduced via a cash in advance constraint is presented the monetary velocity is variable hence money demand does not obey the trivial quantity equation the effects of disturbances in output and money growth on real balances the price level and interest rates are examined monetary policy has effects on real asset prices the fisher relation and the premium on nominal bonds are discussed the precise role of the timing of information and transactions for properties of price levels and interest rates are clarified

the pricing of options on default free bonds recent developments in the finance literature dealing with the valuation of contingent claims have been triggered by black and scholes 2 with their valuation of european options on corporate stocks the type of valuation model derived by black and scholes is attractive because it is independent of preferences this independence is possible due to the fact that the contingent claims are usually assumed to be contingent on traded assets or traded state variables for example a european call option is a claim contingent on the value of the corresponding stock to maintain the independence of the claim from preferences however some variables have to be discarded and considered as constants for example the rate of interest which is not a traded state variable is considered a constant in most of the literature see black and scholes 2 merton 11 and ingersoll 9 though this approximation might not cause important discrepancies in the case of corporate liabilities and options on corporate liabilities the effect of such an approximation on the value of default free bonds and options on default free bonds is more important since these liabilities depend only on the rate of interest

evaluation of callable bonds finite difference methods stability and accuracy the purpose of this paper is to evaluate numerically the semi american callable bond by means of finite difference methods this study implies three results first the numerical error is greater for the callable bond price than for the straight bond price and too large for real applications secondly the numerical accuracy of the callable bond price computed for the relevant range of interest rates depends entirely on the finite difference scheme which is chosen for the boundary points thirdly the boundary scheme which yields the smallest numerical error with respect to the straight bond does not perform best with respect to the callable bond the callable bond is a straight coupon bond with the provision that allows the debtor to buy back or to call the bond for a specified amount the call price plus the accrued interest since the last coupon date at some time the call date s during the life of the bond three types of callable bonds can be observed in financial markets the american callable bond may be repurchased at any time on or before the final redemption day in contrast to the european or semi american counterparts which may only be called at one or several specific dates respectively in the case of semi american bonds the debtor gives the bondholder two months notice the callable bond can be viewed as a compound security which consists of an otherwise identical straight bond and of an embedded call option which is not traded and the price of which is therefore not observable the embedded call option which is written on the underlying straight bond can be viewed as being sold by the initial

ecu interest rates and ecu basket adjustments an arbitrage pricing approach abstract this paper considers arbitrage pricing of bonds and the determination of interest rates in the european currency unit ecu in situations of impending ecu basket adjustments these adjustments disrupt the markets for private ecu assets with a lead of several months the approach of the paper is based on the observation that the ecu is a derivative asset so that in the absence of transaction costs prices of ecu denominated assets should be determined by the prices of the existing member currency assets and the member currencies exchange rates using the technical apparatus of arbitrage pricing theory it is shown how the fundamental arbitrage pricing relationships implied by the derivative character of the ecu have to be adjusted in order to be applicable during periods of ecu basket adjustments

a comparison of yield curve estimation techniques using uk data abstract i compare different methods of estimating the term structure of interest rates on a daily uk treasury bill and gilt data that spans the period from january 1995 to january 1999 in sample and out of sample statistics reveal the superior pricing ability of certain methods characterised by an exponential functional form in addition to these standard goodness of fit statistics model performance is judged in terms of two trading strategies based on model residuals both strategies reveal that parsimonious representations of the term structure perform better than their spline counterparts characterised by a linear functional form this is valid even when abnormal returns are adjusted for market movements linear splines overfit the data and are likely to give misleading results

the reaction of bank stock prices to the international debt crisis abstract in this paper we develop a cross sectional regression approach to estimate the impact of foreign loan exposure on the pricing of u s bank stocks a new approach is required because news about foreign loan problems may arrive incremently over time rather than reaching the market on a few specific dates the way earnings and dividend announcements do consistent with this interpretation we find that foreign loan exposure had a significant impact on the pricing of u s bank stocks during the years 1982 and 1983 but that the stock prices adjusted continually over the two year period rather than jumping on a few particular days

bank capital regulation and the valuation effects of latin american debt moratoriums abstract we examine effects of the mexican and bolivian debt moratoriums on bank share prices and analyze whether bank capital regulation influences these returns we hypothesize that investors perceived that capital deficient banks with exposure to this debt would sustain greater regulatory costs due to increased pressure from regulators to strengthen their capital bases or to reduce leverage consistent with this hypothesis we find that the impact of these debt moratoriums on bank stock returns is more unfavorable for capital deficient banks than for banks that met regulatory standards of capital adequacy

bond price dynamics and options this paper provides a closed form preference free means of valuing a european call option written on a default free pure discount bond investors may not agree upon a theory of the term structure but they will necessarily agree on equilibrium option values further these equilibrium option values may be obtained without recourse to numerical approximation default free pure discount bond prices were posited to follow a non standardized transformed brownian bridge process this specification implicitly incorporates the terminal constraint that the price of a default free pure discount bond equal its face value at maturity contingent claim valuation necessarily involves consideration of terminal constraints on the value of financial securities the brownian bridge specification permits an appropriate means of incorporating a number of such constraints therefore while this paper has considered only the application of the brownian bridge process to the valuation of debt options the introduction of this process may provide for many further financial applications

time dependent variance and the pricing of bond options in this paper we develop a model for valuing debt options that takes into account the changing characteristics of the underlying bond by assuming that the standard deviation of return is proportional to the bond s duration the resulting model uses the bond price as the single state variable and thus preserves much of the simplicity and robustness of the black scholes approach the paper provides comparisons between option prices computed using this model and those using the black scholes and brennan and schwartz models the last decade has seen a dramatic increase in the volatility of bond markets leading to a growing interest in financial instruments that can be used to hedge this risk thus in the u s canada and the u k there has been a proliferation of new interest rate dependent securities such as bond futures options on bonds options on bond futures swap agreements and bonds with option features such as callability putability retractability and so forth with the development of these markets the problems of valuation and the derivation of the hedging strategies have become subjects of increasing importance to both practitioners and academics several valuation methods have been suggested in the literature but so far no consensus has emerged as to the best solution to these problems the simplest approach to the valuation of debt options and probably the most widely used in practice is the black scholes model 3 this method originally developed for the valuation of stock options assumes that the variance of the rate of return on the underlying security is constant while this assumption is plausible for common stocks it is clearly unreasonable for bonds with a finite maturity the distinctive feature of the problem of debt option valuation is that the characteristics of the underlying asset change over time because the price is constrained to converge to the face value of the bond at maturity a second drawback of the black scholes approach is that it assumes a constant short term interest rate an assumption that is clearly inconsistent with stochastic returns on bonds in spite of these problems the black scholes model has been frequently used in practice to value debt options because of its overwhelming simplicity in comparison with other available methods

the pricing of default free interest rate cap floor and collar agreements the paper focuses on the valuation of caps floors and collars in a contingent claim framework under continuous time these instruments are interpreted as options on traded zero coupon bonds the bond prices themselves are used as the underlying stochastic variables this has the advantage that we end up with closed form solutions which are easy to compute special attention is devoted to the choice of the stochastic process appropriate for the price dynamics of the underlying zero coupon bonds the increased volatility of interest rates and the introduction of numerous variable rate instruments have led to a more intensive use of highly sophisticated risk hedging tools among them interest rate caps floors and collars have recently gained a growing popularity an interest rate cap is an agreement between the provider of the cap and a borrower to limit the borrower s floating interest rate to a specific level for a given period of time to be more precise the borrower selects a reference rate to hedge e g libor a period of time to hedge e g 5 years and the level of protection desired e g a ceiling of 200 basis points above the current level of the libor if the market rate exceeds the ceiling rate the cap provider will make payments to the buyer sufficient to bring his rate back to the ceiling when the market rate is below the ceiling no payment is made

the international debt crisis and bank security returns in 1982 this research investigates the reaction of bank security returns to the 20 august 1982 mexican request for the rescheduling of its external debt empirical results show that the reaction of bank stocks was rapid and significantly negative within six days of the published announcem ent prices had adjusted to reflect levels of individual bank exposure which re futes the much longer time impliedin other studies of this event the authors c onclude that the marketreaction was essentially efficient rational and orderly copyright 1987 by ohio state university press

money and interest in a cash in advance economy the authors analyze an aggregative general equilibrium model in which the use of money is motivated by a cash in advance constraint applied to purchases of a subset of consumption goods the system is subject to both real and monetary shocks which are economy wide and observed by all they develop methods for verifying the existence of characterizing and explicitly calculating equilibria copyright 1987 by the econometric society

depositor behavior under macroeconomic risk evidence from bank runs in emerging economies depositor behavior has been associated with bank specific characteristics random runs or contagion episodes using evidence on the 2000 02 bank runs in argentina and uruguay this paper shows that macroeconomic risk is also important few macroeconomic shocks can quickly cause large runs macroeconomic risk affects deposits regardless of traditional bank specific characteristics furthermore bank exposure to macroeconomic factors can explain differences in deposit withdrawals during crises the evolution of bank specific characteristics is mainly driven by macroeconomic factors while the informational content of bank specific variables declines overall depositors seem responsive to risk in a broader sense than that often considered by the literature

the brady plan the 1989 mexican debt reduction agreement and bank stock returns in the united states and japan the authors investigate the impact of the menu approach to debt rescheduling on the market value of two major creditors u s and japanese banks they try to understand how major creditor banks are affected by debt reschedulings and the menu choices they make so that debt deals can be structured in a way that appeals to both creditors and debtor countries they measure the stock market s reaction to the announcement of the brady plan and the mexican debt reduction agreement the brady plan was implemented through the menu approach which acknowledges creditor heterogeneity and provides financing packages that meet the country s financing requirements while still allowing the banks to reduce their exposure the mexican agreement provides an opportunity to test the impact of the brady plan s implementation by examining individual bank s menu choices exposure levels and the market s reaction they explore whether banks were able to make optimal portfolio choices when confronted with the obligation to participate they show that stock prices for different groups of banks reacted quite differently to focal events among all banks u s multinationals showed the strongest positive reaction to the brady announcement and the mexican agreement u s non multinationals do not appear to have been significantly affected by these international debt related events the reaction experienced by all japanese banks was much weaker than that of u s multinationals and was negative for the brady announcement and the initial mexico announcement the authors contend that the lack of a strong reaction was because of the japanese banks relatively low exposure to developing country risk they see the negative market reaction as a reflection of the expectation that a u s initiated debt reduction strategy would not be favorable for japanese banks indeed after the menu choices were announced the market recognized that the japanese banks were treated fairly and corrected itself they do not find that banks that made different choices were treated differently by the market so banks were able to negotiate menu choices in their best interest and to make portfolio choices consistent with their business objectives the results here confirm that the menu approach to debt restructuring may benefit both the creditor banks and the debtor countries

a unified framework for monetary theory and policy analysis search theoretic models of monetary exchange are based on explicit descriptions of the frictions that make money essential however tractable versions of these models typically make strong assumptions that render them ill suited for monetary policy analysis we propose a new framework based on explicit micro foundations within which macro policy can be studied the framework is analytically tractable and easily quantifiable we calibrate the model to standard observations and use it to measure the cost of inflation we find that going from 10 percent to 0 percent inflation is worth between 3 and 5 percent of consumption much higher than previous estimates

heterogeneous creditors and the market value of bank ldc loan portfolios abstract a standard proposition used in many empirical studies is that the value of an ldc loan does not depend on the identity of the lender i test this proposition using bank securities prices and prices for ldc loans trading in the secondary market i find significant cross sectional differences in the sensitivity of bank stocks to changes in the price of ldc loans differences in sensitivity appear to be related to changes in bank exposure to ldcs i also find evidence consistent with the hypothesis that cds are implicitly insured

on the feasibility of arbitrage based option pricing when stochastic bond price processes are involved abstract there are many options which are based on interest rate sensitive assets for example debt options and currency options are best priced when a stochastic bond price process is included however not all stochastic bond price processes are feasible for use in pricing options by standard arbitrage techniques this work draws on the results of harrison and kreps j econ theory 20 1979 381 408 and relates them to pricing in the presence of stochastic bond price processes examples of feasible and infeasible bond price processes are given

banks as monitors of other banks evidence from the overnight federal funds market this study provides evidence that banks are effective monitors of their peers by showing that the interest rate paid on federal funds transactions reflects differences in credit risk across borrowers in addition the size and relative importance in the funds market of the trading institutions are shown to affect the rates charged for overnight borrowing thereby providing insight into the nature of competition in the federal funds market transaction volume and size of transaction effects are uncovered as is evidence of relationship banking between banks these results are made possible by unique data identifying individual federal funds transactions copyright 2001 by university of chicago press

the brazilian default announcement and the contagion effect hypothesis abstract in this paper we use stocl market data to test several hypotheses regarding possible investor reaction to the february 20 1987 brazilian default both the traditional event study approach and a generalized least squares regression using brazilian exposure as an explanatory variable for abnormal returns are used a sample of 46 bank holding companies all listed on the new york or american srock exchanges is divided into groups of no low and high brazilian exposure we find that the initial stock market reaction to the default represents a rational investor response to new bank specific information however the stock market reaction also reveals that not all relevant information was contained in the disclosure announcement further we find some evidence of a contagion effect related to size

a contingent claim analysis of a regulated depository institution abstract a model of financial intermediation to determine the market value of bank equity deposits and deposit insurance is developed the implicit equilibrium interest rate on deposits is derived and analyzed three types of risks are considered in the model interest rate risk financial risk and default risk the effect of different regulatory measures such as capital adequacy reserve and liquidity requirements deposit insurance and interest rate ceilings is analyzed and their impact on the bank behavior is also assessed moreover we investigate the interactions among these measures to determine which are dominant under alternative circumstances and which are redundant

on the determinants of the value of call options on default free bonds the fundamental determinants of the value of an option on a bond are the level and slope of the term structure and the level of interest rate uncertainty competing models that have been developed to price bond options produce similar estimates as long as those models are conditioned on similar values for the fundamental determinants this result is established for simple options with known closed form solutions and for more complex options that require numerical methods for evaluation the finding is confirmed for a wide range of economic conditions and it is shown to be robust with respect to the number and nature of factors that generate interest rate movements copyright 1990 by the university of chicago

the valuation of options on coupon bonds abstract we derive simple closed form expressions for european options on coupon bonds using the general equilibrium term structure framework of cox ingersoll and ross the properties of these options are very different from those implied by the black scholes model for example bond call and put values can move in the same direction as the value of the underlying bond changes this has important implications for hedging interest rate risk with bond options furthermore bond option values can be decreasing functions of interest rate volatility as well as their time to expiration we also examine the properties of american bond options

does the japanese stock market price bank risk evidence from financial firm failures the ability of the japanese stock market to appropriately price the riskiness of japanese financial firms has been frequently questioned particularly in light of japan s widespread financial distress in recent years and poor disclosure requirements this paper examines the response in equity returns of japanese banks to the failure of four commercial banks and two securities firms between 1995 and 1998 using event study methodology the analysis finds that share prices of surviving banks on the whole responded unfavorably to the failures and that financially weaker survivors were more adversely affected this suggests that despite the distress and alleged opaqueness bank shareholders were able to use available indicators of financial condition both to incorporate new information quickly into stock prices and to differentiate among banks

sluggish responses of prices and inflation to monetary shocks in an inventory model of money demand we examine the responses of prices and inflation to monetary shocks in an inventory theoretic model of money demand we show that the price level responds sluggishly to an exogenous increase in the money stock because the dynamics of households money inventories leads to a partially offsetting endogenous reduction in velocity we also show that inflation responds sluggishly to an exogenous increase in the nominal interest rate because changes in monetary policy affect the real interest rate in a quantitative example we show that this nominal sluggishness is substantial and persistent if inventories in the model are calibrated to match u s households holdings of m2

liquidity a new monetarist perspective this essay surveys the new monetarist approach to liquidity work in this literature strives for empirical and policy relevance plus rigorous foundations questions include what is liquidity is money essential in achieving desirable outcomes which objects can or should serve in this capacity when can asset prices differ from fundamentals what are the functions of commitment and collateral in credit markets how does money interact with credit and intermediation what can and should monetary policy do the research summarized emphasizes the micro structure of frictional transactions and studies how institutions like monetary exchange credit arrangements or intermediation facilitate the exchange process

money search and business cycles monetary models that specify explicit frictions to generate money demand have been developed over the last 20 years and have been used to address many questions in this article i investigate the short run properties of a particular model considering a number of versions based on some modeling choices all versions feature flexible prices i find that in many aspects both real and nominal the model resembles other more reduced form models some variations of the model come closer to matching some key nominal facts than a reduced form model the model also generates counter cyclical markups in line with the data

debt equity swaps regulation k and bank stock returns abstract since the early 1980s the financial health of several highly levered ldcs has become increasingly precarious their financial problems in turn imply potentially serious financial problems for their creditors foremost among whom are some of the largest banks in the american financial system in order to relieve some of the pressure on the lending firms the board of governors has recently amended regulation k which provides guidelines for international banking operations to allow for unrestricted investment in foreign nationalized firms through the mechanism of the debt equity swap this paper examines the capital market reaction to the regulatory change and we find that 1 investors on average viewed the change as a wealth increasing event 2 the magnitude of the market reaction was significant and positively related to the level of foreign lending exposure and 3 among ldc lenders the capital market reaction differed significantly between money center and non money center banks

the variability of velocity of money in a search model abstract we construct a dynamic equilibrium model where there is costly search in the goods market and the labor market incorporating shocks to money growth and productivity we calibrate the model to the us time series data to examine the model s quantitative predictions on aggregate variables and in particular on the variability of consumption velocity of money despite the fact that money is the only asset the model captures most of the variability of velocity in the data it also generates realistic predictions on the moments of other variables and provides persistent propagation of the shocks the model generates these results largely because costly search gives an important role to the extensive margin of trade

bank stock returns and economic growth previous research has established i that a country s financial sector influence future economic growth and ii that stock market index returns affect future economic growth we extend and tie together these two strands of the growth literature by analyzing the relationship between banking industry stock returns and future economic growth using dynamic panel techniques to analyze panel data from 18 developed and 18 emerging markets we find a positive and significant relationship between bank stock returns and future gdp growth that is independent of the previously documented relationship between market index returns and economic growth we also find that much of the informational content of bank stock returns is captured by country specific and institutional characteristics such as bank accounting disclosure standards banking crises enforcement of insider trading law and government ownership of banks

investment and hedging under a stochastic yield curve abstract this paper examines portfolio decisions involving both fixed and non fixed income securities two state variables the short term and the long term interest rates fully determine the bonds prices and partly influence the other assets prices we propose first a methodology for determining optimal portfolios in such a context and then use that methodology to solve the portfolio problem of investors whose long term bond holdings are constrained which generates undesirable interest rate risk that are hedged with futures contracts the individual futures positions which involve several hedging components and the futures market equilibrium open interest are derived and analysed

valuing debt options empirical evidence abstract a two factor model using the instantaneous rate of interest and the return on a consol bond to describe the term structure of interest rates the brennan schwartz model is used to derive theoretical prices for american call and put options on us government bonds and treasury bills these model prices are then compared with market prices the theoretical model used to value the dept options also provides hedge ratios which may be used to construct zero investment portfolios which in theory are perfectly riskless several trading strategies based on these riskless portfolios are examined

asset trading mechanisms and expansionary policy abstract previous authors have argued that the otimal monetary policy is contractionary if buyers value consumption substantially more than sellers there is some randomness and informational constraints make asset trading useful we show that there is an incentive compatible expansionary policy that dominates all incentive compatible contractionary policies
