definition consistent measurement of exchange market pressure currencies can be under severe pressure but in a managed exchange rate regime that is not fully visible via the change in the exchange rate the literature has proposed a way to measure such exchange market pressure emp indirectly by adding interest rate changes and forex interventions to the exchange rate change we demonstrate that this measure is not consistent with the definition of emp and develop a new measure that is consistent this is first derived within the commonly used monetary exchange rate model then we generalize the analysis by avoiding the use of an exchange rate model we find that the interest rate should not be taken in the first difference form used so far but rather in level form and relative to the interest rate chosen if the country had no exchange rate objective applications on the european monetary system and east asian crises confirm that this improvement is highly relevant in practice

monetary policy rule of thumb consumers and external habits a g7 comparison this paper extends the standard new keynesian dynamic stochastic general equilibrium dsge model to agents who cannot smooth consumption i e spenders and are affected by external consumption habits although these assumptions are not new their joint consideration strongly affects some theoretical and empirical results addressed by the recent literature by deriving closed form solutions we identify different demand regimes and show that they are characterized by specific features regarding dynamic stability and monetary policy effectiveness we also evaluate our model by stochastic simulations obtained from the bayesian parameters estimates for the g7 economies from posterior impulse responses we address the empirical relevance of the different regimes and provide comparative evidence on the heterogeneity of monetary policy effects among countries

multiple equilibrium overnight rates in a dynamic interbank market game abstract we analyse a two period model of the interbank market i e the market where banks trade liquidity we assume that banks do not take the interbank interest rate as given but instead negotiate on interest rates and transaction volumes with each other the solution concept applied is the shapley value we show that there are a multiplicity of average equilibrium interest rates of the first period so that the average interest rate in this period does not convey any information on the expected liquidity situation on the interbank market as the banks control not only the transaction volumes but also the interest rates they can leave the interest rates constant and adjust the transaction volumes when for example a liquidity deficit becomes more likely

intraindustry structure and the ease of strategic change there has been considerable recent work in industrial organization emphasizing the importance of group stratification within industries the thrust of this literature is that in empirical work and in particular in investigating public policy problems differences across firms within an industry may be crucial this paper is intended as a contribution to the empirical literature of group structures in this paper i examine patterns of strategic group membership in a number of industries and analyze changes in the strategies used by firms in particular i provide a series of rather simple exploratory tests of the importance of intraindustry strategic differences in a number of industries

organizational transformation as punctuated equilibrium an empirical test the punctuated equilibrium model of organizational transformation has emerged as a prominent theoretical framework for explaining fundamental changes in patterns of organizational activity to date

assessing organizational fitness on a dynamic landscape an empirical test of the relative inertia thesis this paper proposes an empirical framework for evaluating the relative structural inertia hypothesis a central assumption of organizational ecology theories in stark contrast to the tenets of strategic management the relative inertia thesis claims that organizations are typically unable to match structural changes to their competitive environments in a timely fashion the hypothesis is tested for the hospital industry in california during the 1980 90 time frame strategic movements in a competition landscape are tracked using a variant of the jaccard similarity coefficient which has been applied in numerous studies of biological competition findings indicate that few hospitals are able to overcome inertial forces in adapting their service portfolios furthermore the ability of hospitals to strategically reposition themselves decreases markedly with provider density analyses also investigate the relation between organizational attributes e g age size mission and portfolio scope and adaptability implications for both ecological and strategic theory are pursued 1997 john wiley sons ltd

optimal simple monetary and fiscal rules under limited asset market participation the combination of limited asset market participation and consumption habits generates indeterminacy for empirically plausible calibrations of a business cycle model characterized by price and nominal wage rigidities equilibrium determinacy is restored by demand management policies based on simple fiscal rules in this regard fiscal control of nominal income growth is particularly effective in addition the complementarity between the taylor rule and the fiscal feedback on nominal income growth produces relatively large welfare gains limiting both aggregate and intragroup volatilities

strategic group formation and performance the case of the u s pharmaceutical industry 1963 1982 the focus of this paper is on three major questions 1 what is the theoretical rationale for the strategic group concept 2 does strategic group membership have performance implications and 3 are strategic groups and membership in strategic groups stable characteristics of industries a statistical procedure is proposed to longitudinally identify strategic groups the empirical setting is the u s pharmaceutical industry over the period 1963 82 while performance differences are found in terms of market share profitability differences between groups are not observed neither are differences found in terms of risk and risk adjusted performance these results are attributed to the existence of performance variation within each strategic group a dynamic model of competitive repositioning is proposed which helps integrate the findings from the study

determinacy and identification with taylor rules the new keynesian taylor rule theory of inflation determination relies on explosive dynamics by raising interest rates in response to inflation the fed induces ever larger inflation unless inflation jumps to one particular value on each date however economics does not rule out explosive inflation so inflation remains indeterminate attempts to fix this problem assume that the government will choose to blow up the economy if alternative equilibria emerge by following policies we usually consider impossible the taylor rule is not identified without unrealistic assumptions thus taylor rule regressions do not show that the fed moved from passive to active policy in 1980

cheap talk and strategic rounding in libor submissions interbanking rates were until recently based on judgmental estimates of borrowing costs we interpret this as a cheap talk game that allowed banks to communicate nonverifiable information about their opportunity cost to potential counterparties under normal market conditions there is a welfare maximizing equilibrium where banks truthfully disclose their borrowing cost but in times of financial stress only coarse equilibria survive we take this prediction to the data and show that banks round more frequently if the risk of the bank increases rounding is also more frequent for the more liquid short term rates and certain benchmark maturities

a search based model of the interbank money market and monetary policy implementation we present a search based model of the interbank money market and monetary policy implementation banks are subject to reserve requirements and the central bank tenders reserves interbank payments redistribute holdings and banks trade with each other in a decentralized over the counter market the central bank provides standing facilities where banks can either deposit surpluses or borrow to cover shortfalls of reserves overnight the model provides insights on liquidity trading volume and rate dispersion in the interbank market features largely absent from the canonical models in the tradition of poole 1968 and fits a number of stylized facts for the eurosystem observed during the recent period of unconventional monetary policies moreover it provides insights on the implications of different market structures

resource and market based determinants of performance in the u s banking industry this paper explores the implications of studying industry competitive patterns at the level of resource accumulation and the relationship between resource endowments and firm performance outcomes in the u s banking industry it uses the strategic group framework to evaluate two models of rivalry and performance and concludes by discussing the implications of the findings for competitive analysis strategic group theory and the banking industry

a search based theory of the on the run phenomenon we propose a model in which assets with identical cash flows can trade at different prices infinitely lived agents can establish long positions in a search spot market or short positions by first borrowing an asset in a search repo market we show that short sellers can endogenously concentrate in one asset because of search externalities and the constraint that they must deliver the asset they borrowed that asset enjoys greater liquidity a higher lending fee specialness and trades at a premium consistent with no arbitrage we derive closed form solutions for small frictions and provide a calibration generating realistic on the run premia

the intraday price of money evidence from the e mid interbank market we provide empirical evidence based on tick by tick data for the e mid euro area interbank market covering 2003 and 2004 that the overnight interest rate shows a clear downward pattern throughout the operating day thus a positive hourly interest rate half basis point implicitly emerges from the intraday term structure of the overnight rate such a pattern was not detected in the mid 1990s we explain this evolution as an outcome of the recent trend toward real time settlement the estimated intraday interest rate is lower than in the united states this is due to the different cost of central bank daylight credit

entrepreneurial strategy and the presence of small firms a model is presented hypothesizing that the level of small firm presence in any given industry emanates from the exogenous stock of entrepreneurial talent a stochastic element of managerial and entrepreneurial talent entry deterrence and the entrepreneurial strategy deployed by small firms using data newly released by the u s small business administration the hypothesis is tested for a sample of 247 four digit standard industrial classification industries spanning the entire spectrum of firm sizes we find that consistently for all the measures of small firm size and for all of the time periods used the existence of entry deterrence and reliance upon innovative strategy explains a significant proportion of the variation in the presence of small firms

modeling the dynamics of strategic fit a normative approach to strategic change this study develops and tests a dynamic perspective on strategic fit drawing from contingency and resource based arguments in the strategy and organizational theory literatures we propose a distinctive analytical approach to identify environmental and organizational contingencies that should predict changes in a firm s strategy and the performance implications of such changes we test our model using extensive longitudinal data from over 4000 u s savings and loan institutions during a period when many s ls considered changing strategic direction the findings support our model of dynamic strategic fit specifically we find that 1 the timing direction and magnitude of strategic changes can be logically predicted based on differences in specific environmental forces and organizational resources and 2 organizations that deviated from our model s prediction of dynamic strategic fit i e changed more or changed less than our model prescribed experienced negative performance consequences we conclude by discussing the implications of our approach and findings for future research on strategic fit and strategic change copyright 2000 john wiley sons ltd

a micro model of the federal funds market this paper demonstrates that valuable insights into the determination of federal funds rates can be gained through modeling the micro decisions of market participants fed fund demand functions are derived for different bank valuation functions and several implications are discussed specifically it is i possible to rationalize the observation that large banks are net purchasers and small banks net sellers of fed funds ii to explain the positive spread of fed funds rates over other short term money market rates and iii to link the size of this spread to the federal reserve s underlying monetary policy strategy

asset prices and liquidity in an exchange economy i develop an asset pricing model in which financial assets are valued for their liquidity the extent to which they are useful in facilitating exchange as well as for being claims to streams of consumption goods the implications for average asset returns the equity premium puzzle and the risk free rate puzzle are explored in a version of the model that nests the work of mehra and prescott 1985

fiscal policy and liquidity traps with heterogeneous agents this paper explores global dynamics in a monetary model with limited asset market participation and the zero lower bound on nominal interest rates it is shown that a rise in government transfers to non ricardian consumers financed by debt based taxes to ricardian consumers is capable of escaping disinflationary paths typically convergent to a liquidity trap fiscal policy does not need to be unsustainable at the low inflation steady state to avoid liquidity traps as argued in the context of the standard single representative agent setup

interest rate dispersion and volatility in the market for daily funds abstract the purpose of this paper is to study the determinants of equilibrium in the market for daily funds we use the eonia panel database which includes daily information on the lending rates applied by contributing commercial banks the data clearly show an increase in both the time series volatility and the cross section dispersion of rates towards the end of the reserve maintenance period these increases are highly correlated we design a model to account for these empirical facts our theoretical model shows how the operational framework of monetary policy causes a reduction in the elasticity of the supply of funds by banks throughout the reserve maintenance period this reduction in the elasticity together with market segmentation and heterogeneity is able to generate distributions for the interest rates and quantities traded with the same properties as in the data we also investigate the effects of the changes in the eurosystem s operational framework enacted on march 2004 for interest rate behaviour

rule of thumb consumers meet sticky wages it has been argued that rule of thumb consumers substantially alter the determinacy properties of simple interest rate rules and the dynamics of an otherwise standard new keynesian model in this paper we show that nominal wage stickiness helps re establishing standard results key findings are that wage stickiness i affects the shape of determinacy regions in the parameters space restoring the relevance of the taylor principle for the conduct of monetary policy ii implies that a rise in consumption in response to an innovation in government spending is not a robust feature of the model

the general equilibrium effects of fiscal policy estimates for the euro area abstract this paper describes a dynamic stochastic general equilibrium model featuring a fraction of non ricardian agents in order to estimate the effects of fiscal policy in the euro area the model takes into account distortionary taxation on labor and capital income and on consumption while expenditures are broken down into purchases of goods and services compensation of public employees and transfers to households a newly computed quarterly data set of fiscal variables is used our results point to the prevalence of mild keynesian effects of public expenditures in particular although innovations in fiscal policy variables tend to be rather persistent government purchases of goods and services and compensations for public employees have small and short lived expansionary effects on private consumption while innovations in transfers to households show a slightly more sizeable and lasting effect the effects are more significant on the revenue side decreases in labor income and consumption tax rates have sizeable effects on consumption and output while a reduction in capital income tax favors investment and output in the medium run finally our estimates suggest that fiscal policy variables contribute little to the cyclical variability of the main macro variables

monetary policy transmission with interbank market fragmentation this paper shows how interbank market fragmentation disrupts the transmission of monetary policy fragmentation is the fact that banks depending on their country of location have different probabilities of default on their interbank borrowings once fragmentation is introduced into standard theoretical models of monetary policy implementation excess liquidity arises endogenously this leads short term interest rates to depart from the central bank policy rates using data on monetary policy operations i show that this mechanism has been at work in the euro area since 2008 the model is used to analyze conventional and unconventional monetary policy measures

fixed costs and the behavior of the federal funds rate abstract this paper presents an equilibrium model of the federal funds market that ties movements in the funds rate to changes in the supply of reserves and to a fixed cost facing banks that borrow at the discount window it is found that the existence of the fixed cost is capable of explaining a number of features of the funds market in particular it is critical for explaining occasional instances of extremely high funds rates it also provides an explanation for heterogeneous behavior across banks towards the discount window and for higher average funds rates at the end of maintenance periods

some results on the optimality and implementation of the friedman rule in the search theory of money abstract i characterize a large family of monetary policies that implement milton friedman s prescription of zero nominal interest rates in a monetary search economy with multiple assets and aggregate uncertainty this family of optimal policies is defined by two properties i the money supply must be arbitrarily close to zero for an infinite number of dates and ii asymptotically on average over the dates when fiat money plays an essential role the growth rate of the money supply must be at least as large as the rate of time preference

asset prices liquidity and monetary policy in an exchange economy i formulate a model in which money coexists with equity shares on a risky aggregate endowment agents can use equity as a means of payment so shocks to equity prices translate into aggregate liquidity shocks that disrupt the mechanism of exchange i characterize a family of optimal monetary policies and find that the resulting equity prices are independent of monetary considerations i also study a perturbation of the family of optimal policies that targets a positive constant nominal interest rate and find that in this case the real equity return includes a liquidity return that depends on monetary considerations

a dynamic network model of the unsecured interbank lending market abstract we introduce a dynamic network model of interbank lending and estimate the parameters by indirect inference using network statistics of the dutch interbank market from february 2008 to april 2011 we find that credit risk uncertainty and peer monitoring are significant factors in explaining the sparse core periphery structure of the market and the presence of relationship lending shocks to credit risk uncertainty lead to extended periods of low market activity intensified by reduced peer monitoring moreover changes in the central bank s interest rate corridor have both a direct effect on the market as well as an indirect effect by changing banks monitoring efforts

a model for the federal funds rate target this paper is a statistical analysis of the manner in which the federal reserve determines the level of the federal funds rate target one of the most publicized and anticipated economic indicators in the financial world the paper introduces new statistical tools for forecasting a discrete valued time series such as the target and suggests that these methods in conjunction with a focus on the institutional details of how the target is determined can significantly improve on standard vector autoregression forecasts of the effective federal funds rate we further show that the news that the fed has changed the target has statistical content substantially different from the news that the fed failed to make an anticipated target change causing us to challenge some of the conclusions drawn from standard linear var impulse response functions

liquidity regulation and the implementation of monetary policy in addition to revamping existing rules for bank capital basel iii introduces a new global framework for liquidity regulation one part of this framework is the liquidity coverage ratio lcr which requires banks to hold sufficient high quality liquid assets to survive a 30 day period of market stress as monetary policy typically involves targeting the interest rate on loans of one of these assets central bank reserves it is important to understand how this regulation may impact the efficacy of central banks current operational frameworks we introduce term funding and an lcr requirement into an otherwise standard model of monetary policy implementation our model shows that if banks face the possibility of an lcr shortfall then the usual link between open market operations and the overnight interest rate changes and the short end of the yield curve becomes steeper our results suggest that central banks may want to adjust their operational frameworks as the new regulation is implemented

liquidity premia in dynamic bargaining markets abstract this paper develops a search theoretic model of the cross sectional distribution of asset returns abstracting from risk premia and focusing exclusively on liquidity in contrast with much of the transaction cost literature it is not assumed that different assets carry different exogenously specified trading costs instead different expected returns due to liquidity are explained by the cross sectional variation in tradeable shares the qualitative predictions of the model are consistent with much of the empirical evidence

systemic illiquidity in the federal funds market this paper shows how the intra day allocation and pricing of overnight loans of federal funds reflect the decentralized inter bank market in which these loans are traded a wouldbe borrower or lender typically finds a counterparty institution by direct bilateral contact once in contact say by telephone the two counterparties to a potential trade negotiate terms that reflect their incentives for borrowing or lending as well as the attractiveness of their respective options to forego a trade and to continue shopping around this overthe counter otc pricing and allocation mechanism is quite distinct from that of most centralized markets such as an electronic limit order book market in which every order is anonymously exposed to every other order with a centralized order crossing algorithm while there is a significant body of research on the micro structure of specialist and limit order book markets most otc markets do not have comprehensive transactionslevel data available for analysis the federal funds market is a rare exception we go beyond a previous study by craig furfine 1999 of the microstructure of the federal funds market by modeling how the likelihood of matching a particular borrower with banking studies federal reserve bank of new york 33 liberty street new york ny 10045 we are grateful for support and data from the federal reserve bank of new york and for comments from guillaume plantin jamie mcandrews craig furfine michael fleming and anonymous federal funds traders we have also benefited from comments by andrew metrick jeremy stein ken french larry harris owen lamont john taylor and randy westerfield the views expressed here are not necessarily those of the federal reserve bank of new york or the federal reserve system

winter is possibly not coming mitigating financial instability in an agent based model with interbank market abstract we develop a macroeconomic agent based model to study how financial instability can emerge from the co evolution of interbank and credit markets and the policy responses to mitigate its impact on the real economy the model is populated by heterogenous firms consumers and banks that locally interact in different markets in particular banks provide credit to firms according to a basel ii or iii macro prudential frameworks and manage their liquidity in the interbank market the central bank performs monetary policy according to different types of taylor rules we find that the model endogenously generates market freezes in the interbank market which interact with the financial accelerator possibly leading to firm bankruptcies banking crises and the emergence of deep downturns this requires the timely intervention of the central bank as a liquidity lender of last resort moreover we find that the joint adoption of a three mandate taylor rule tackling credit growth and the basel iii macro prudential framework is the best policy mix to stabilize financial and real economic dynamics however as the liquidity coverage ratio spurs financial instability by increasing the pro cyclicality of banks liquid reserves a new counter cyclical liquidity buffer should be added to basel iii to improve its performance further finally we find that the central bank can also dampen financial instability by employing a new unconventional monetary policy tool involving active management of the interest rate corridor in the interbank market

voluntary reserve targets we study monetary policy implementation through an operating regime involving voluntary reserve targets vrts operating regimes based on reserve requirements may lead to a collapse in interbank trade as they have since the financial crisis we show that no matter the abundance of reserves vrts encourage market activity and support the central bank s control over interest rates we consider i the impact of anticipated and unanticipated liquidity injections by the central bank on market outcomes and ii a comparison with the implementation framework currently adopted by the federal reserve overall a vrt framework may provide several advantages over other frameworks

exit strategies for monetary policy abstract in response to the financial crisis of 2007 08 all major central banks decreased interest rates to historically low levels and created large excess reserves central bankers and academics currently discuss how to implement monetary policy going forward we find that paying interest on reserves ior is optimal if the central bank has full fiscal support if the central bank has no fiscal support reducing reserves is optimal this can be achieved by reserve absorbing operations which hold the size of the balance sheet constant or by selling assets which reduces the size of the balance sheet

monetary policy implementation in a negative rate environment monetary policy implementation could in theory be constrained by deeply negative rates since overnight market participants may have an incentive to invest in cash rather than lend to other participants

the micromechanics of the federal funds market implications for day of the week effects in funds rate variability the federal funds rate arguably is the most important interest rate in the u s capital market because it plays a central role in monetary policy and the term structure this paper examines the micromechanics of the funds market we show that in a continuous market with asynchronous trading regulatory constraints and accounting conventions that focus agents attention on discrete time instants have important implications for the dynamics of trading activity and realized market prices we also exhibit a model of the market that explains observed regularities in the intertemporal behavior of the funds rate

payment obligations reserve requirements and the demand for central bank balances we develop a model in which a bank s demand for reserves depends on the joint distribution of transactions reserve requirements and the interest rate by devoting resources to its liquidity management a bank can save on costly reserves required to settle its payments on time we test the model with data from the largest banks in the swiss interbank clearing system we find that the turnover ratio the speed with which a bank turns over its reserves in the payment system depends largely on the aggregate value of its payments we also find that reserve requirements impose a highly uneven burden on the banks

unconventional fiscal policy at the zero bound when the zero lower bound on nominal interest rates binds monetary policy cannot provide appropriate stimulus we show that in the standard new keynesian model tax policy can deliver such stimulus at no cost and in a time consistent manner there is no need to use inecient policies such as

the over the counter theory of the fed funds market a primer we present a dynamic over the counter model of the fed funds market and use it to study the determination of the fed funds rate the volume of loans traded and the intraday evolution of the distribution of reserve balances across banks we also investigate the implications of changes in the market structure as well as the effects of central bank policy instruments such as open market operations the discount window lending rate and the interest rate on bank reserves

interest rate corridors and reserves abstract this paper evaluates reserves regimes versus interest rate corridors which have become competing frameworks for monetary policy implementation rate corridors relying on lending and deposit facilities to create ceilings and floors for overnight interest rates evince mixed results on controlling volatility reserve requirements allow period average smoothing of interest rates but even if remunerated are subject to reserve avoidance activities a system of voluntary period average reserve commitments could offer equivalent rate smoothing advantages if central banks created symmetric opportunity costs of meeting or falling short of period average reserve requirements or commitments they could achieve flat reserve demand on settlement day

portfolio choice and pricing in illiquid markets abstract this paper studies portfolio choice and pricing in markets in which immediate trading may be impossible it departs from the literature by removing restrictions on asset holdings and finds that optimal positions depend significantly and naturally on liquidity when expected future liquidity is high agents take more extreme positions given that they do not have to hold those positions for long when they become undesirable consequently larger trades should be observed in markets with more frequent trading liquidity need not affect the price significantly however because liquidity has offsetting impacts on different agents demands this result highlights the importance of unrestricted portfolio choice the paper draws parallels with the transaction cost literature and clarifies the relationship between the price level and the realized trading frequency in this literature

monetary policy in a channel system abstract channel systems for conducting monetary policy are becoming increasingly popular despite its popularity the consequences of implementing policy with a channel system are not well understood we develop a general equilibrium framework of a channel system and study the optimal policy a novel aspect of the channel system is that a central bank can tighten or loosen its policy without changing its policy rate this policy instrument has so far been overlooked by a large body of the literature on the optimal design of interest rate rules

trade dynamics in the market for federal funds we develop a model of the market for federal funds that explicitly accounts for its two distinctive features banks have to search for a suitable counterparty and once they have met both parties negotiate the size of the loan and the repayment the theory is used to answer a number of positive and normative questions what are the determinants of the fed funds rate how does the market reallocate funds is the market able to achieve an efficient reallocation of funds we also use the model for theoretical and quantitative analyses of policy issues facing modern central banks

corridor system and interest rates volatility and asymmetry the corridor system in its current form is believed to reduce the volatility of overnight interest rates and to eliminate any chance of persistent upward or downward bias the model presented here serves to highlight two main findings one is that a central bank can further reduce the volatility of overnight interest rates by allowing banks some flexibility to meet their reserve targets within a small range as observed in the uk data the second is that a seemingly symmetric corridor may be asymmetric in practice due to several distortions as the uk and euro area data suggest

efficiency and bargaining power in the interbank loan market using detailed transactions level data on interbank loans we examine the efficiency of an overnight interbank lending market and the bargaining power of its participants our analysis relies on the equilibrium concept of the core which imposes a set of no arbitrage conditions on trades in the market for canada s large value transfer system we show that although the market is fairly efficient systemic inefficiency persists throughout our sample the level of inefficiency matches distinct phases of both the bank of canada s operations as well as phases of the 2007 8 financial crisis we find that bargaining power tilted sharply toward borrowers as the financial crisis progressed and surprisingly toward riskier borrowers

the savers spenders theory of fiscal policy the macroeconomic analysis of fiscal policy is usually based on one of two canonical models the barro ramsey model of infinitely lived families or the diamond samuelson model of overlapping generations this paper argues that neither model is satisfactory and suggests an alternative in the proposed model some consumers plan ahead for themselves and their descendants while others live paycheck to paycheck this model is easier to reconcile with the essential facts about consumer behavior and wealth accumulation and it yields some new and surprising conclusions about fiscal policy

a model of job and worker flows we develop a model of gross job and worker flows and use it to study how the wages permanent incomes and employment status of individual workers evolve over time and how they are affected by aggregate labor market conditions our model helps explain various other features of labor markets such as the size and persistence of the changes in income that workers experience due to displacements or job to job transitions the length of job tenures and unemployment duration and the amount of worker turnover in excess of job reallocation we also examine the effects that labor market institutions and public policy have on the gross flows as well as on the resulting wage distribution employment and aggregate output in the equilibrium from a theoretical point of view we study the extent to which the competitive equilibrium achieves an efficient allocation of resources

day to day monetary policy and the volatility of the federal funds rate we propose a model of the interbank money market with an explicit role for central bank intervention and periodic reserve requirements and study the interaction of profit maximizing banks with a central bank targeting interest rates at high frequency the model yields predictions on biweekly patterns of the federal funds rate s volatility and on its response to changes in target rates and in intervention procedures such as those implemented by the fed in 1994 theoretical results are consistent with empirical patterns of interest rate volatility in the u s market for federal funds

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

limited asset markets participation monetary policy and inverted aggregate demand logic abstract this paper incorporates limited asset markets participation in dynamic general equilibrium and develops a simple analytical framework for monetary policy analysis aggregate dynamics and stability properties of an otherwise standard business cycle model depend nonlinearly on the degree of asset market participation while moderate participation rates strengthen the role of monetary policy low enough participation causes an inversion of results dictated by conventional wisdom the slope of the is curve changes sign the taylor principle is inverted optimal welfare maximizing discretionary monetary policy requires a passive policy rule and the effects and propagation of shocks are changed however a targeting rule implementing optimal policy under commitment delivers equilibrium determinacy regardless of the degree of asset market participation our results may justify fed s behavior during the great inflation period

day to day monetary policy and the volatility of the federal funds interest rate we propose a model of the interbank money market with an explicit role for central bank intervention and periodic reserve requirements and study the interaction of profit maximizing banks with a central bank targeting interest rates at high frequency the model yields predictions on biweekly patterns of the federal funds rate s volatility and on its response to changes in target rates and in intervention procedures such as those implemented by the fed in 1994 theoretical results are consistent with empirical patterns of interest rate volatility in the u s market for federal funds

economic analysis and the quest for competitive advantage curred in the past decade between applied microeconomists and those who study business strategy business strategists have cast up a series of questions for industrial economists who have responded with numerous applications of economic theory and quantitative research methods this interchange has been fruitful and indeed more fruit remains for the picking i shall argue for centering the collaborative effort on what may be called committed competition rivalrous moves among incumbent producers that involve resource commitments that are irrevocable for nontrivial periods of time most concerns of business strategy are with policy choices that

search in asset markets market structure liquidity and welfare this paper investigates how market structure affects efficiency and several dimensions of liquidity in an asset market to this end we generalize the search theoretic model of financial intermediation of darrell duffie et al 2005 to allow for entry of dealers and unrestricted asset holdings

strategic leaders or strategic groups a longitudinal data envelopment analysis of the u s brewing industry abstract this paper builds on strategic group theory which was originally introduced to help explain the observed variation in firm profitability across an industry this paper applies data envelopment analysis dea to identify both strategic leaders the best practice players in the industry and strategic groups to examine which are the source of the most sustained heterogeneity in the performance of u s brewers contrary to the prevalent research approach in strategy and organization research which places a premium on empirical analyses that maximize explanation of average behavior daft and lewin 1990 this paper examines extremal observations as a means of studying or inducing theories about best practice such as best strategies or most effective organization design lewin and minton 1986 the paper argues that significant insights new knowledge and unexpected theories can arise from studying the best or worst of a population the paper applies dea to a longitudinal reanalysis of u s brewing data to demonstrate its usefulness for obtaining new insights from identifying and studying industry outliers the paper raises important questions about the construct of strategic groups and illustrates how competing theories can be deduced and analyzed for explaining performance heterogeneity in the u s brewing industry

estimating the impact of the r d tax credit on strategic groups in the pharmaceutical industry abstract the economic recovery and tax act of 1981 provided a 25 percent tax credit for increases in research and experimentation expenditures previous studies have shown considerable controversy about the effectiveness of various tax credits this study focuses on the response of the strategic groups in the pharmaceutical industry to the credit four strategic groups were formed using different levels of research intensity research sales and relative cash flow margin cash flow sales the change in research intensity following enactment of the tax credit was estimated the analysis found that the tax credit caused an increase in r d expenditures in addition the r d tax credit appears to have contributed to increased competitive r d spending among the firms in the pharmaceutical industry

the impact of return on collateral in a channel system we empirically investigate the relationship between the return on collateral and monetary policy implementation in the channel system recent developments in monetary theory suggest that the return on government assets which measures the opportunity cost of holding collateral should have negative impacts on the interest rate spread and the interbank market rate the central bank should set a higher spread when the return on collateral is below a cutoff but implements a lower spread when the return on collateral is higher than the cutoff the interbank market rate tends to lie above the policy target rate when the return on collateral is low and vice versa we use data from eurozone area and six industrialized countries to test these theoretical implications we propose two econometric models one is more structural and closely related to the monetary model to test the negative relationships and the other is based on the threshold autoregression model to detect the potential cutoffs our findings provide conditional support for the negative impact of return on collateral jel e40 e52 e58

monetary policy implementation and overnight rate persistence overnight money market rates are the predominant operational target of monetary policy as a consequence central banks have redesigned the implementation of monetary policy to keep the deviations of the overnight rate from the key policy rate small and short lived this paper uses fractional integration techniques to explore how the operational framework of four major central banks afiects the persistence of overnight rates our results suggest that a well communicated and transparent interest rate target of the central bank is a particularly important condition for a low degree of overnight rate persistence

the analytics of monetary non neutrality in the sidrauski model abstract this note analytically characterizes the equilibrium dynamics of the sidrauski model and reaches three conclusions regarding monetary policy i it is typically not neutral ii in some cases it is not neutral even in the steady state and iii a policy that has the nominal interest rate falling over time may sustain higher output and consumption forever

leaning against the wind during financial disruptions market makers provide liquidity by absorbing external selling pressure they buy when the pressure is large accumulate inventories and sell when the pressure alleviates this paper studies optimal dynamic liquidity provision in a theoretical market setting with large and temporary selling pressure and order execution delays i show that competitive market makers offer the socially optimal amount of liquidity provided they have access to sufficient capital if raising capital is costly this suggests a policy role for lenient central bank lending during financial disruptions

a theory of money and marketplaces this article considers an infinitely repeated economy with divisible fiat money the economy has many marketplaces that agents choose to visit in each marketplace agents are randomly matched to trade goods there exist a variety of stationary equilibria in some equilibrium each good is traded at a single price whereas in another every good is traded at two different prices there is a continuum of such equilibria which differ from each other in price and welfare levels however it is shown that only the efficient single price equilibrium is evolutionarily stable

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

open mouth operations abstract this paper explains how central bank statements rather than open market operations can be used to implement monetary policy in the extreme policy instruments can be held constant and yet interest rates will evolve along the path desired by the central bank we show how the recent implementation of monetary policy in new zealand works in this way using announcement data from new zealand we find that open mouth operations lead to large changes in interest rates across all maturities and these changes cannot be explained by open market operations implications are drawn for monetary policy in other jurisdictions

strategic group dynamics a longitudinal study was conducted of strategic group dynamics over periods of economic stability growth and decline in international offshore oil drilling some changes in group strategy were ob

liquidity requirements and the interbank loan market an experimental investigation abstract we develop a stylized interbank market environment and use it to evaluate with experimental methods the effects of liquidity requirements baseline and liquidity regulated regimes are analyzed in a simple shock environment which features a single idiosyncratic shock and in a compound shock environment in which the idiosyncratic shock is followed by a randomly occurring second stage shock interbank trading of the illiquid asset follows each shock in the simple shock environment we find that liquidity regulations reduce the incidence of bankruptcies but at a large loss of investment efficiency in the compound shock environment liquidity regulations not only impose a loss of investment efficiency but also fail to reduce bankruptcies

the indeterminacy of prices under interest rate pegging the non ricardian case abstract this paper investigates the issue of price level indeterminacy under a pure interest rate peg in models that depart from standard ricardian assumptions using a monetary version of blanchard s finite horizons model i find wealth effects operating on government bonds are not sufficient to determine a unique price level next i consider price determination under a non ricardian fiscal authority i show that if agents rationally perceive the possibility of fiscal default the price level is again indeterminate i conclude that departures from ricardian equivalence are not sufficient to ensure a unique price level under a monetary policy of pure interest rate pegging

bank liquidity interbank markets and monetary policy a major lesson of the recent financial crisis is that the interbank lending market is crucial for banks facing large uncertainty regarding their liquidity needs this paper studies the efficiency of the interbank lending market in allocating funds we consider two different types of liquidity shocks leading to di erent implications for optimal policy by the central bank we show that when confronted with a distribu tional liquidity shock crisis that causes a large disparity in the liquidity held among banks the central bank should lower the interbank rate this view implies that the traditional tenet prescribing the separation between prudential regulation and mon etary policy should be abandoned in addition we show that during an aggregate liquidity crisis central banks should manage the aggregate volume of liquidity two di erent instruments interest rates and liquidity injection are therefore required to cope with the two di erent types of liquidity shocks finally we show that failure to cut interest rates during a crisis erodes financial stability by increasing the risk of bank runs
