bank spread with uncertain deposit level and risk aversion abstract this paper derives a model of the banking firm under uncertainty and risk aversion the selection of the bank s optimal spread between loan and deposit rates is emphasized the model s results provide some implications for bank asset quality capital regulation and deposit insurance for example it is shown that increases in the level of equity capital tend to increase the bank s spread under dara this implies an improvement in bank asset quality on the other hand as the deposit supply function becomes more volatile the bank s spread narrows which implies a decline in the quality of the bank s assets

the relative valuation of caps and swaptions theory and empirical evidence although traded as distinct products caps and swaptions are linked by noarbitrage relations through the correlation structure of interest rates using a string market model we solve for the correlation matrix implied by swaptions and examine the relative valuation of caps and swaptions we find that swaption prices are generated by four factors and that implied correlations are lower than historical correlations long dated swaptions appear mispriced and there were major pricing distortions during the 1998 hedge fund crisis cap prices periodically deviate significantly from the no arbitrage values implied by the swaptions market the growth in interest rate swaps during the past decade has led to the creation and rapid expansion of markets for two important types of swap related derivatives interest rate caps and swaptions these over the counter derivatives are widely used by many firms to manage their interest rate risk exposure and collectively represent the largest class of fixed income options in the financial markets the international swaps and derivatives association isda estimates that the total notional amount of caps and swaptions outstanding at the end of 1997 was over 4 9 trillion which was more than 300 times the 15 billion notional of all chicago board of trade treasury note and bond futures options combined caps and swaptions are generally traded as separate products in the financial markets and the models used to value caps are typically different from those used to value swaptions furthermore most wall street firms use a piecemeal approach in calibrating their models for caps and swaptions making it difficult to evaluate whether these derivatives are fairly priced

credit rationing and credit view empirical evidence from an ethical bank in italy attempts have been made in the empirical literature to identify credit rationing and its determinants using balance sheet data or evidence from corporate surveys however observational equivalence identification problems and interview biases are serious problems in these studies we analyze directly the determinants of credit rationing in credit files by examining the differencebetweentheamountsdemandedbyandsuppliedtoeachborrower as shown by official bank records our findings provide microeconomic evidence that supports the credit view hypothesis by showing that the european central bank refinancing rate is significantly and positively related to partial but not total credit rationing this finding is consistent with the hypothesis that this variable affects the total volume of bank loans

corner solutions in duality models a cross section analysis of dairy production decisions comrner solutions are often observed in cross section samples of farm level production decisions an estimation strategy is presented and applied to a uniquely comprehensive data set for pennsylvania dairy farms a complete set of choice functions is derived consistent with multiple outputs and multiple inputs expected profit maximation and the existence of comrner solutions with respect to the labor hiring decision results illustrate that substantial estimation bias may occur if the existence of comrner solutions is not recognized estimated elasticities of choices with respect to input and net output prices indicate substantial responsiveness of choice to price results indicate that changes in education and acreage operated result in substantial changes in output and input mixes and that the differences in results for farms with and without hired labor are substantial

on the determinants of bank interest margins under credit and interest rate risks abstract this paper explores the determinants of optimal bank interest margins based on a simple firm theoretical model under multiple sources of uncertainty and risk aversion the model demonstrates how cost regulation credit risk and interest rate risk conditions jointly determine the optimal bank interest margin decision we find that the bank interest margin is positively related to the bank s market power to the operating costs to the degree of credit risk and to the degree of interest rate risk an increase in the bank s equity capital has a negative effect on the spread when the bank faces little interest rate risk the effect of rising interbank market rate on the spread is ambiguous and depends on the net position of the bank in the interbank market our findings provide alternative explanations for the empirical evidence concerning bank spread behavior

when does the prime rate change abstract we study the frequency of prime rate changes we model the prime rate as a time series variable that can be changed only at some cost this yields a logit model in which the probability of a prime rate change is a function of market variables we test this model using data from a micro data set that gives the dating of prime rate changes the results indicate that adjustment costs are important to the prime rate adjustment process and that changes in exogenous variables have a significantly larger effect on the probability of a prime rate increase than decrease

the economics of small business finance the roles of private equity and debt markets in the financial growth cycle abstract this article examines the economics of financing small business in private equity and debt markets firms are viewed through a financial growth cycle paradigm in which different capital structures are optimal at different points in the cycle we show the sources of small business finance and how capital structure varies with firm size and age the interconnectedness of small firm finance is discussed along with the impact of the macroeconomic environment we also analyze a number of research and policy issues review the literature and suggest topics for future research

robust bidding and revenue in descending price auctions abstract we study the properties of dutch auctions in an independent private value setting where bidders face uncertainty over the type distribution of their opponents and evaluate their payoffs by the worst case from a set of probabilistic scenarios in contrast to static auction formats participants in the dutch auction gradually learn about the valuations of other bidders we show that the transmitted information can lead to changes in the worst case distribution and thereby shift a bidder s payoff maximizing exit price over time we characterise the equilibrium bidding function in this environment and show that the arriving information leads bidders to exit earlier at higher prices as a result the dutch auction systematically generates more revenue than the first price auction

what s different among banks abstract based on commercial paper being a nearly perfect substitute for certificates of deposits cds and cd reserve requirements creating a higher cost of funds for banks fama shows that the banking industry must have some monopoly power relative to other financial institutions his analysis does not resolve whether this monopoly power is vested in banks collectively vis a vis other financial institutions or if the monopoly power extends to the level of individual banks using an event study framework to examine the elimination of a reserve requirement we find significant evidence of monopoly power at the level of individual banks

asymmetric quantile analysis of the swedish mortgage price discovery process based on swedish banking data we discover robust and significantly positive asymmetric price transmission apt effects over all analysed regression quantiles of our mortgage interest rates with even larger positive apt for the higher percentiles the analysis was enabled through unique access to a swedish bank s seb own records of their true borrowing costs our central contribution is that there is a higher propensity for the bank to rapidly increase its mortgage interest rates for customers following an increase in its borrowing costs compared with the propensity for the bank to decrease its customers mortgage rates subsequent to a corresponding borrowing cost decrease

a dynamic ellsberg urn experiment two rationality arguments are used to justify the link between conditional and unconditional preferences in decision theory dynamic consistency and consequentialism dynamic consistency requires that ex ante contingent choices are respected by updated preferences consequentialism states that only those outcomes which are still possible can matter for updated preferences we test the descriptive validity of these rationality arguments with a dynamic version of ellsberg s three color experiment and find that subjects act more often in line with consequentialism than with dynamic consistency

uncertainty aversion and dynamic consistency this paper applies a proposal of m machina 1989 for updating nonexpected utility preferences to d schmeidler s 1989 nonadditive probability model the authors discover that the updated preferences may not themselves satisfy schmeidler s axioms despite this the updates of uncertainty averse preferences are themselves uncertainty averse copyright 1996 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

do firms get the financing they want measuring credit rationing experienced by small businesses in the u s this paper measures the extent to which small businesses in the united states in the late 1980s were able to access the external credit finance they desired we argue that a comprehensive definition of credit rationing must account for both a creditworthy firms that apply for and are denied financing and b creditworthy firms that decide not to apply for desired external financing given expectations about how long it may take to obtain financing and the evolution of investment opportunities

how does equity capital cost affect bank performance during a financial crisis this article theoretically examines how equity capital cost affects return performance and safety of a bank and how this effect varies across a financial crisis comparing to a normal time when the bank manager s performance reveals the like of higher equity return and the dislike of higher equity risk we derive two main results first an increase in the bank s equity capital cost from an increase of the interest rate of the federal funds results in a reduced loan risk taking at an increased optimal bank interest margin implying better bank performance second by ignoring the dislike we find that the better performance is reinforced during a financial crisis but is reduced during a normal time financial crises and the dislike preference as such contribute a relatively low return and the stability of banking activities

financial frictions and policy cooperation a case with monopolistic banking and staggered loan contracts abstract do financial frictions call for cross border policy cooperation this paper investigates the implications of financial frictions in the form of staggered loan contracts supplied by monopolistic banks for monetary policy using the linear quadratic lq framework we show that policy cooperation yields long run gains in addition to gains from stabilizing inefficient fluctuations over the business cycle as usually found in models with price rigidities the ramsey optimal steady states differ between cooperation and noncooperation such gains from cooperation arise irrespective of capital account liberalization

the banking industry under uncertain monetary policy abstract the optimal loan decisions of banks are shown to be dependent on the banks rational forecast of the future federal funds rate which in turn is related to the policy rule used by the fed consequently a change in the policy of the fed will alter the reduced form model of the banking industry this result brings into question the fed s ability to predict and control the money stock under the procedure adopted by the fed between october 1979 and september 1982

on booms that never bust ambiguity in experimental asset markets with bubbles we study the effect of ambiguity on the formation of bubbles and on the occurrence of crashes in experimental asset markets a la smith suchanek and williams 1988 we extend their framework to an environment where the fundamental value of the asset is ambiguous we show that when the fundamental value is ambiguous asset prices tend to be lower than when it is risky although bubbles form in both the ambiguous and the risky environments additionally bubbles do not crash in the ambiguous case whereas they do so in the risky one these findings regarding depressed prices and the absence of crashes in the presence of ambiguity are in line with recent theoretical work stressing the crucial role of ambiguity to account for surprisingly low equity prices high returns as well as herding in asset markets

the price of a smile hedging and spanning in option markets the volatility smile changed drastically around the crash of 1987 and new option pricing models have been proposed to accommodate that change deterministic volatility models allow for more flexible volatility surfaces but refrain from introducing additional risk factors thus options are still redundant securities alternatively stochastic models introduce additional risk factors and options are then needed for spanning of the pricing kernel we develop a statistical test based on this difference in spanning using daily s p 500 index options data from 1986 95 our tests suggest that both in and out of the money options are needed for spanning the findings are inconsistent with deterministic volatility models but are consistent with stochastic models that incorporate additional priced risk factors such as stochastic volatility interest rates or jumps article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

implementation under ambiguity abstract we introduce the idea of implementation under ambiguity in particular we study maximin efficient notions for an ambiguous asymmetric information economy i e economies where agents preferences are maximin a la wald 1950 the interest on the maximin preferences lies in the fact that maximin efficient allocations are always incentive compatible de castro and yannelis 2009 a result which is false with bayesian preferences a noncooperative notion called maximin equilibrium is introduced which provides a noncooperative foundation for individually rational and maximin efficient notions specifically we show that given any arbitrary individually rational and ex ante maximin efficient allocation there is a direct revelation mechanism that yields the efficient allocation as its unique maximin equilibrium outcome thus an incentive compatible individually rational and efficient outcome can be reached by means of noncooperative behavior under ambiguity

a model of the commercial loan rate this paper explores the theoretical and empirical determinants of the commercial loan rate charged by commercial banks based on a model of financial intermediary behavior which assumes monopolistic competition in asset and liability markets the model incorporates the constraint that banks must maintain at least a minimum quantity of bonds in asset portfolios equations are estimated on a time series basis to explain the behavior of commercial loan rates over the period 1953 to 1980 the evidence appears consistent with the hypothesis that commercial banks operate in a market characterized by imperfect competition and that they explicitly set loan rates the development of large scale econometric models has focused attention on the operation of the commercial loan market because of the importance of commercial loan activity in the transmission of monetary policy moreover it is commonly accepted that the quantity of commercial loans or changes in these loans has an important influence on the holding of free reserves by commercial banks and this implies that the commercial loan market has an effect on the supply of money 2 nevertheless the determinants of commercial loan rates have drawn relatively little analytical attention previous work on the commercial loan market has generally focused on the question of whether this market is characterized by credit rationing 3 most studies assume that the commercial loan market is generally competitive but at times the commercial loan rate does not clear the market the quantity of loans transacted is constrained by the supply function and commercial banks engage in nonprice rationing of customers a corollary of this rationing hypothesis is that events in the deposit market have an important influence on the quantity of commercial loans 4 the purpose of this paper is to explore the determinants of the commercial

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

optimal monetary policy with countercyclical credit spreads we study optimal monetary policy in a new keynesian dynamic stochastic general equilibrium dsge model with a credit channel and relationship lending in banking we show that borrowers bank specific deep habits give rise to countercyclical credit spreads which in turn make optimal monetary policy depart substantially from price stability under both discretion and commitment our analysis shows that the welfare costs of setting monetary policy under discretion with respect to the optimal ramsey plan and of using simpler suboptimal policy rules are strictly increasing in the magnitude of deep habits in credit markets and market power in banking

real exchange rate dynamics revisited a case with financial market imperfections abstract in this paper we investigate the relationship between real exchange rate dynamics and financial market imperfections for this purpose we first construct a new open economy macroeconomics noem model that incorporates staggered loan contracts as a simple form of the financial market imperfections our model with such a financial market friction replicates persistent volatile and realistic hump shaped responses of real exchange rates which have been thought very difficult to materialize in standard noem models remarkably these realistic responses can materialize even with both supply and demand shocks such as cost push loan rate and monetary policy shocks this implies that the financial market development is a key element for understanding real exchange rate dynamics

modeling the banking firm a survey this paper reports on the status of the literature on micro bank modeling and assesses our understanding of the banking firm s optimal behavior this is no mean task for much has been written on banking broadly defined over the past couple of decades the review is developed in pieces each major subproblem is outlined and the analysis used to deal with the issue explicated this is not the best way to summarize the development of a field it should be immediately recognized one would prefer to have a smooth continuum of development moving the frontier of knowledge evenly through time and across subareas yet this is rarely the way a field develops more likely individual questions attract attention and are the subjects of a substantial number of contributions after a time the field moves on to the new area of interest the banking field is no exception before embarking upon the review however a couple of lines should be devoted to previous attempts there have been essentially three first pyle 1972 analyzes the uncertainty portfolio models at a time when little existed in the literature and hence one finds the review a bit vague and sketchy baltensperger s contributions 1978 1980 are the next serious and rather extensive reviews the quality of these

prime rate changes is there an advantage in being first this article analyzes the impact of prime rate changes on stock prices of prime rate change initiating banks relative to noninitiating banks the prime rate as a sticky price is analyzed and the potential directions and sizes of information effects are discussed and empirically examined it is found that prime rate increases generally convey bad news about the initiating banks prime rate decreases in contrast have weakly positive effects on the initiating banks prime rate change announcements are also found to have some effect on banks other than the initiating bank implying that contagion effects exist copyright 1993 by university of chicago press

short run and long run dynamics of farm land allocation panel data evidence from denmark1 this study develops and estimates a dynamic multi output model of farmers land allocation decisions that allows for the gradual adjustment of allocations that can result from crop rotation practices and quasi fixed capital constraints estimation is based on micro panel data from danish farmers that include acreage output and variable input utilization at the crop level results indicate that there are substantial differences between the short run and long run land allocation behaviour of danish farmers and that there are substantial differences in the time lags associated with different crops to our knowledge this is the first dynamic micro model of land allocation estimated on data from the temperate climate zone since similar farming conditions are found in northern europe and parts of the united states and canada this result may be of wider interest

bank liquidity providing in a real synergy management under a cap based valuation since banks often lend via commitments their lending and deposit taking may be two manifestations of one primitive function the provision of liquidity on demand we explore this function under a cap based valuation we find that i the strike price of the cap based valuation increases the bank s liquid asset holdings by increasing its loan rate and loan commitment rate with the strategic rate adjustment complements and decreases the bank s external finance need by increasing its deposit rate when the bank realizes a less risky state of the world and ii the number of caplet days decreases the bank s liquid asset holdings by decreasing its loan rate and loan commitment rate with the strategic rate adjustment complements and the strategic timing substitutes and increases the bank s external finance need by decreasing its deposit rate with the strategic timing substitutes when the bank realizes a more risky state our findings provide alternative explanations concerning the bank s liquidity funct

estimating substitution and expansion effects using a profit function framework this study reports a first attempt to derive all the relevant information with respect to the structure of production of an industry using knowledge of only a profit function using estimates of a profit function for canadian agriculture a procedure to separate substitution and expansion effects for both inputs and outputs was implemented information concerning net input and output substitution and complementarity possibilities were obtained the most important empirical results suggest that the hypothesis of nonjoint production of crop and animal outputs in canadian agriculture cannot be rejected and that hired and operator labor are complements rather than substitutes

the intersection of market and credit risk abstract economic theory tells us that market and credit risks are intrinsically related to each other and not separable we describe the two main approaches to pricing credit risky instruments the structural approach and the reduced form approach it is argued that the standard approaches to credit risk management creditmetrics creditrisk and kmv are of limited value when applied to portfolios of interest rate sensitive instruments and in measuring market and credit risk empirically returns on high yield bonds have a higher correlation with equity index returns and a lower correlation with treasury bond index returns than do low yield bonds also macro economic variables appear to influence the aggregate rate of business failures the creditmetrics creditrisk and kmv methodologies cannot reproduce these empirical observations given their constant interest rate assumption however we can incorporate these empirical observations into the reduced form of jarrow and turnbull 1995b drawing the analogy risk 5 63 70 model here default probabilities are correlated due to their dependence on common economic factors default risk and recovery rate uncertainty may not be the sole determinants of the credit spread we show how to incorporate a convenience yield as one of the determinants of the credit spread for credit risk management the time horizon is typically one year or longer this has two important implications since the standard approximations do not apply over a one year horizon first we must use pricing models for risk management some practitioners have taken a different approach than academics in the pricing of credit risky bonds in the event of default a bond holder is legally entitled to accrued interest plus principal we discuss the implications of this fact for pricing second it is necessary to keep track of two probability measures the martingale probability for pricing and the natural probability for value at risk we discuss the benefits of keeping track of these two measures

a more robust definition of subjective probability the goal of choice theoretic derivations of subjective probability is to separate a decisionmaker s underlying beliefs subjective probabilities of events from their preferences attitudes toward risk classical derivations have all relied upon some form of the marschak samuelson independence axiom or the savage sure thing principle which imply that preferences over lotteries conform to the expected utility hypothesis this paper presents a choice theoretic derivation of subjective probability in a savage type setting of purely subjective uncertainty which neither assumes nor implies that the decisionmaker s preferences over lotteries necessarily conform to the expected utility hypothesis copyright 1992 by the econometric society

a general model of the banking firm under conditions of monopoly uncertainty and recourse abstract we develop a stochastic programming model of the monopolistic competition banking firm it assumes the bank faces a downward sloping loan demand curve and is a price taker in securities markets uncertainty and liquidity requirements are incorporated bank decisions are made within a two stage framework where realized disturbances that violate constraints can be rectified ex post at a cost the results are 1 optimal loan and deposit rates are positive functions of the recourse penalty 2 asset liability decisions are interdependent and elastically supplied deposits lower the loan rate 3 the effect of uncertainty depends upon the penalty rate level

credit swap valuation this review of the pricing of credit swaps a form of derivative security that can be viewed as default insurance on loans or bonds begins with a description of the credit swap contract turns to pricing by reference to spreads over the risk free rate of par floating rate bonds of the same quality and then considers model based pricing the role of asset swap spreads as a reference for pricing credit swaps is also considered

the paradox of liquidity the more liquid a firm s assets the greater their value in a short notice liquidation it is generally thought that a firm should find it easier to raise external finance against more liquid assets this paper focuses on the dark side of liquidity greater asset liquidity reduces the firm s ability to commit to a specific course of action as a result greater asset liquidity can in some circumstances reduce the firm s capacity to raise external finance firms with excessively liquid assets are in the best position to finance illiquid projects this leads us to a theory of financial intermediation and disintermediation based on the liquidity of assets

sealed bid auctions with ambiguity theory and experiments this study presents a laboratory experiment of the first and second price sealed bid auctions with independent private values where the distribution of bidder valuations may be unknown in our experimental setting in first price auctions bids are lower with the presence of ambiguity this result is consistent with ambiguity loving in a model that allows for different ambiguity attitudes we also find that the first price auction generates significantly higher revenue than the second price auction with and without ambiguity

a parametric nonlinear model of term structure dynamics recent nonparametric estimation studies pioneered by ait sahalia document that the diffusion of the short rate is similar to the parametric function r superscript 1 5 estimated by chan et al whereas the drift is substantially nonlinear in the short rate these empirical properties call into question the efficacy of the existing affine term structure models and beg for alternative models which admit the observed behavior this article presents such a model our model delivers closed form solutions for bond prices and a concave relationship between the interest rate and the yields we show that in empirical analyses our model outperforms the one factor affine models in both time series as well as cross sectional tests article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

ambiguity aversion games against nature and dynamic consistency abstract several papers adopting an axiomatic approach to study decision making under ambiguity aversion have produced conflicting predictions about how decision makers would behave in simple dynamic urn problems we explore the concepts of ambiguity aversion and dynamic consistency with examples of dynamic games against nature basically a malevolent nature puts balls into the urn and a fair nature draws them out depending on the game various choices that seem inconsistent with static notions of ambiguity aversion or dynamic consistency are consistent with subgame perfection in the dynamic 3 color ellsberg urn problem with 30 red balls and 60 blue or green balls the decision maker could strictly prefer to bet on blue green at time 0 and to switch to red green after learning that the ball is not green

decision theory under ambiguity we review recent advances in the field of decision making under uncertainty or ambiguity we start with a presentation of the general approach to a decision problem under uncertainty as well as the standard bayesian treatment and issues with this treatment we present more general approaches choquet expected utility maximin expected utility smooth ambiguity and so forth that have been developed in the literature under the name of models of ambiguity sensitive preferences we draw a distinction between fully subjective models and models incorporating explicitly some information we review definitions and characterizations of ambiguity aversion in these models we mention the challenges posed by some of the models presented we end with a review of part of the experimental literature and applications of these models to economic settings

some evidence on the empirical significance of credit rationing this paper examines the credit rationing debate using detailed contract information on over one million commercial bank loans from 1977 to 1988 while commercial loan rates are sticky consistent with rationing this stickiness varies with loan contract terms in ways that are not predicted by equilibrium credit rationing theory in addition the proportion of new loans issued under commitment does not increase significantly when credit markets are tight despite the fact that borrowers without commitments can be rationed whereas commitment borrowers are contractually insulated from rationing overall the data suggest that equilibrium rationing is not a significant macroeconomic phenomenon

lapm a liquidity based asset pricing model the intertemporal capm predicts that an asset s price is equal to the expectation of the product of the asset s payoff and a representative consumer s intertemporal marginal rate of substitution this paper develops an alternative approach to asset pricing based on corporations desire to hoard liquidity our corporate finance approach suggests new determinants of asset prices such as the distribution of wealth within the corporate sector and between the corporate sector and the consumers also leverage ratios capital adequacy requirements and the composition of savings affect the corporate demand for liquid assets and thereby interest rates starting with the capital asset pricing model capm derived by sharpe 1964 lintner 1965 and mossin 1966 market finance has emphasized the role of consumers time preference and risk aversion in determining asset prices the intertemporal consumption based asset pricing model e g rubinstein 1976 lucas 1978 breeden 1979 harrison and kreps 1979 cox ingersoll and ross 1985 hansen and jagannathan 1991 predicts that an asset s current price is equal to the expectation conditioned on current information of the product of the asset s payoff and a representative consumer s intertemporal marginal rate of substitution imrs while fundamental this dominant paradigm for pricing assets has some wellrecognized shortcomings see below and there is clearly scope for alternative and complementary approaches this paper begins developing one such approach based on aggregate liquidity considerations 1 our starting point is that the productive and financial spheres of the economy have autonomous demands for financial assets and that their valuations for these assets are often disconnected from the representative consumer s corporate demand for financial assets is driven by the desire to hoard liquidity in order to fulfill future cash needs in contrast with the

optimal bank interest margin under capital regulation and deposit insurance this paper examines the relationships among capital regulation deposit insurance and the optimal bank interest margin in a model where loan losses are the source of uncertainty changes in capital regulation or deposit insurance premiums have direct effects on the bank s interest margin an increase in bank capital requirement or in deposit insurance premiums results in a reduced interest margin under nonincreasing risk aversion comparative static analysis also explores the relation between asset quality and interest margin it is shown that a mean preserving spread of the distribution of loan losses results in a reduced margin

dynamic choice and the common ratio effect an experimental investigation the common ratio effect is a well attested violation of expected utility theory this paper uses four principles of dynamic choice to characterise alternative theoretical strategies for explaining the effect it reports an experiment which tests these principles and by implication several well known accounts of the common ratio effect unlike previous work the experimental design uses real financial incentives without presupposing any dynamic choice principles we find violation of a principle of timing independence which is part of most existing theories of dynamic choice we examine the implications of this finding for decision theory and economics

interest rate pass through and asymmetric adjustment evidence from the federal funds rate operating target period this study examines the long run interest rate pass through of the federal funds rate to the prime rate and whether there is asymmetric adjustment in the prime rate using the enders siklos 2001 momentum threshold autoregressive model over the period february 1987 to october 2005 once allowance is made for the endogenously determined structural break in the cointegrating relationship in april 1996 the adjustment of the prime rate to changes in the federal funds rate appears asymmetric with upward rigidity a result contrary to previous studies which found that the prime rate exhibits downward rigidity the finding of upward rigidity in the prime rate lends support for the customer reaction and adverse selection hypotheses moreover the empirical evidence seems to support the observation of increased pass through as a result of heightened competition in the banking industry as well as the federal reserve s enhanced transparency in monetary policy during the 1990s

pricing interest rate derivatives a general approach the relationship between affine stochastic processes and bond pricing equations in exponential term structure models has been well established we connect this result to the pricing of interest rate derivatives if the term structure model is exponential affine then there is a linkage between the bond pricing solution and the prices of many widely traded interest rate derivative securities our results apply to m factor processes with n diffusions and l jump processes the pricing solutions require at most a single numerical integral making the model easy to implement we discuss many options that yield solutions using the methods of the article

unspanned stochastic volatility evidence from hedging interest rate derivatives most existing dynamic term structure models assume that interest rate derivatives are redundant securities and can be perfectly hedged using solely bonds we find that the quadratic term structure models have serious difficulties in hedging caps and cap straddles even though they capture bond yields well furthermore at the money straddle hedging errors are highly correlated with cap implied volatilities and can explain a large fraction of hedging errors of all caps and straddles across moneyness and maturities our results strongly suggest the existence of systematic unspanned factors related to stochastic volatility in interest rate derivatives markets

foundations of the structure conduct performance paradigm in banking this paper employs an explicit model of the banking firm to derive formally and thereby assess critically the most commonly tested relationships implied by the structure conduct performance paradigm as it applies to the banking industry these include the relationship between loan rates and market concentration deposit rates and market concentration and bank profitability and market concentration the necessary assumptions and simplifications implicit in past empirical studies are outlined and suggestions for future empirical implementation of the underlying model are presented copyright 1991 by ohio state university press
