a model of the liquidity structure based on asset indivisibility abstract although the notion of a liquidity structure of asset yields is widely accepted there do not seem to be models of such a structure here the liquidity of an asset is taken to be its transaction velocity the amount traded per unit time divided by the stock assets are assumed to be indivisible and to differ in size trade using such assets is implied by pairwise matching and absence of double coincidence in produced goods it is shown that a sufficiently large asset has a lower velocity and a higher yield than a sufficiently small asset

coalition proof trade and the friedman rule in the lagos wright model the lagos wright model a monetary model in which pairwise meetings alternate in time with a centralized meeting has been extensively analyzed but always using particular trading protocols here trading protocols are replaced by two alternative notions of implementability one that allows only individual defections and one that also allows cooperative defections in meetings it is shown that the first best allocation is implementable under the stricter notion without taxation if people are sufficiently patient and if people are free to skip the centralized meeting then lump sum taxation used to pay interest on money does not enlarge the set of implementable allocations

inflation and asset returns in a monetary economy postwar u s data are characterized by negative correlations between real equity returns and inflation and by positive correlations between real equity returns and money growth these patterns are closely matched quantitatively by an equilibrium monetary asset pricing model the model also implies negative correlations between expected asset returns and expected inflation and it predicts that the inflationasset return correlation will be more strongly negative when inflation is generated by fluctuations in real economic activity than when it is generated by monetary fluctuations the co movements of real asset returns inflation and money growth have been studied extensively over the past fifteen years table i displays some of the statistical properties of these series using quarterly u s data from 1959 to 1990 note first the significantly negative correlation between real equity returns and inflation note also the negative correlation between inflation and the ex post real return to nominally riskless bonds while this fact is not particularly surprising numerous studies conclude that the correlations between ex ante real asset returns and expected inflation are also negative 2 in contrast to these patterns the correlation between money growth and real equity returns is weakly positive in the data while the correlation between money growth and the real bond return is virtually zero initially these empirical patterns were viewed as anomalies negative correlations between inflation and ex post real stock returns contradict the traditional view that equities ought to act as an inflation hedge 3 negative correlations between expected inflation and ex ante real returns violate the

a walrasian theory of money and barter we study a barter economy in which each good is produced in two qualities and no trader can distinguish between the qualities of those goods he neither consumes nor produces we show that in competitive equilibrium there exists a unique good the one for which the discrepancy between qualities is smallest that serves as the medium of exchange this good mediates every trade equilibrium is inefficient because production of the medium would be lower if it were not for its mediating role introducing fiat money enhances welfare by eliminating this distortion however high inflation drives traders back to the commodity medium

liquidity monetary policy and unemployment a new monetarist approach we discover a consumption channel of monetary policy in a model with money and government bonds when the central bank withdraws government bonds short term or long term through open market operations it lowers returns on bonds the lower return has a direct negative impact on consumption by households that hold bonds and an indirect negative impact on consumption by households that hold money as a result firms earn less profits from production which leads to higher unemployment the existence of such a consumption channel can help us understand the effects of unconventional monetary policy

modeling foreign equity control in sino foreign joint ventures with neural networks abstract equity control is one of the key areas of research in international business this study employs artificial neural networks anns to model foreign equity control comparisons are made with traditional statistical modeling approaches it was found that anns produce a more parsimonious set of independent variables that yield higher classification rates than logistic regression thus it can be concluded that anns with their complex nonlinear structure are able to model the relationship between transaction cost factors and majority minority ownership and percent equity ownership more accurately than the linear statistical approaches

reallocation of production inputs in a monetary economy abstract this paper explains the return correlation between money and competing assets the coexistence puzzle and the effect of inflation on output as the model allows sellers to use lands as an input buyers portfolios can rebalance from money to land in response to inflation expanding sellers production which explains the positive correlation between output and inflation and the negative correlation between the return on money and land although the return on money is dominated by land both assets are used in equilibrium

barter and monetary exchange under private information the authors develop a model of production and exchange with uncertainty concerning the quality of commodities and study the role of fiat money in ameliorating frictions caused by private information the model is specified so that without private information only high quality commodities are produced and there is no welfare gain from using money with private information there can be equilibria and sometimes multiple equilibria where low quality commodities are produced and money can increase welfare money works by promoting useful production and exchange in efficient monetary equilibria agents adopt strategies that increase the probability of acquiring high quality output copyright 1994 by american economic association

on the coexistence of money and higher return assets and its social role this paper adopts mechanism design to investigate the coexistence of at money and higherreturn assets we consider an economy with pairwise meetings where at money and riskfree capital compete as means of payment as in lagos and rocheteau 2008 the trading mechanism in pairwise meetings is chosen among all individually rational renegotiation proof mechanisms to maximize society s welfare we show that in any stationary monetary equilibrium capital commands a higher rate of return than at money

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

bargaining with an agenda gradual bargaining is represented by an agenda a family of increasing sets of joint utilities parameterized by time a solution for gradual bargaining specifies an agreement at each time we axiomatize an ordinal solution i e one that is covariant with order preserving transformations of utility it can be viewed as the limit of step by step bargaining in which the agreement of the last negotiation becomes the disagreement point for the next the stepwise agreements may follow the nash solution the kalai smorodinsky solution or many others and still yield the ordinal solution in the limit

2002 lawrence r klein lecture liquidity and asset prices we broadly define liquid assets or monetary assets as any asset that can be readily sold in the market and can be held by a number of people in succession before maturity we ask in what environment is the circulation of liquid assets essential for the smooth running of the economy by developing a canonical model of a monetary economy i e where the circulation of liquid assets is essential we are able to examine the interaction between liquidity asset prices and aggregate economic activity

monetary policy and asset prices a mechanism design approach we investigate the eects of monetary policy on asset prices in economies where assets are traded periodically in over the counter otc markets with bilateral meetings between buyers and sellers the trading mechanism in pairwise meetings is designed to maximize social welfare taking as given the frictions in the environment e g lack of commitment and limited enforcement and monetary policy we show that asset price bubbles emerge in a constrained e cient monetary equilibrium only if liquidity is abundant and the rst best allocation is implementable in contrast if liquidity is scarce assets are priced at their fundamental value in any constrained e cient monetary equilibrium in which case an increase in in ation has no eect on asset prices but it reduces output and welfare finally for low in ation rates the bursting of an asset price bubble can be an optimal response to a shock that reduces assets resalability

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

payments and liquidity under adverse selection informational asymmetries regarding the future value of assets affect their role in exchange i construct a random matching economy composed of two assets a risk free bond and a lucas tree whose terminal value is privately known to its holder no restrictions are imposed on payment arrangements the main finding supports a pecking order theory of payments agents use their risk free bonds first in order to finance their spending shocks and they use their information sensitive assets only if their holdings of bonds are depleted the theory has implications for the optimal provision of risk free bonds the structure of asset returns and liquidity

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

toward a theory of international currency we use the framework of random matching games and develop a two country model of the world economy in which two national currencies compete and may be circulated as media of exchange there are multiple equilibria which differ in the areas of circulation of the two currencies in one equilibrium the two national currencies are circulated only locally in another one currency is circulated as an international currency there is also an equilibrium in which both currencies are accepted internationally we also find an equilibrium in which the two currencies are directly exchanged we first characterize the existence conditions of these equilibria in terms of the relative country size and the degree of economic integration and then use an evolutionary approach to equilibrium selection to explain the evolution of the international currency as the two economies become more integrated some welfare implications are also discussed for example a country can improve its national welfare by letting its own currency circulate internationally provided the domestic circulation is controlled for when the total supply is fixed however a resulting currency shortage may reduce the national welfare

optimal monetary policy what we know and what we don t know in this article i examine the current state of knowledge about optimal monetary policy i distinguish between two literatures basic and applied the basic literature is explicit about the frictions that generate a positive value for money and make it socially beneficial the applied literature is not i describe the recent lessons about monetary policy that we have learned from each literature and discuss how the two distinct approaches may be usefully combined

money and capital as competing media of exchange we construct a model where capital competes with fiat money as a medium of exchange and we establish conditions on fundamentals under which fiat money can be both valued and socially beneficial when the socially efficient stock of capital is too low to provide the liquidity agents need they overaccumulate productive assets to use as media of exchange when this is the case there exists a monetary equilibrium that dominates the nonmonetary one in terms of welfare under the friedman rule fiat money provides just enough liquidity so that agents choose to accumulate the same capital stock a social planner would

a monetary explanation of the equity premium term premium and risk free rate puzzles this paper develops and estimates a monetary model that offers an explanation of some puzzling features of observed returns on equities and default free bonds the key feature of the model is that some assets other than money play a special role in facilitating transactions which affects the rate of return that they offer the model is capable of producing a low risk free rate a high equity premium and an average positive relationship between maturity and term premium for default free bonds the model s implications for the joint distribution of asset returns velocity inflation money growth and consumption growth are also compared to the behavior of these variables in the u s economy

a liquidity based resolution of the uncovered interest parity puzzle a new monetary theory is set out to resolve the uncovered interest parity puzzle uip puzzle it explores the possibility that liquidity properties of money and nominal bonds can account for the puzzle a key concept in our model is that nominal bonds carry liquidity premium due to their medium of exchange role as either collateral or means of payment in this framework no arbitrage condition ensures a positive comovement of real return on money and nominal bonds thus when inflation in one country becomes relatively lower i e real return on this currency is relatively higher its nominal bonds should also yield higher real return we show that their nominal returns can also become higher under the economic environment where collateral pledgeability and or liquidity of nominal bonds and or collateralized credit based transactions are relatively bigger since a currency with lower inflation is expected to appreciate the high interest currency does indeed appreciate in this case i e the uip puzzle is no longer an anomaly in our model our liquidity based theory in fact has interesting implications on many empirical observations that risk based explanations find difficult to reconcile with

on money as a medium of exchange we analyze economies in which individuals specialize in consumption and production and meet randomly over time in a way that implies that trade must be bilateral and quid pro quo nash equilibria in trading strategies are characterized certain goods emerge endogenously as media of exchange or commodity money depending both on their intrinsic properties and on extrinsic beliefs there are also equilibria with genuine fiat currency circulating as the general medium of exchange we find that equilibria are not generally pareto optimal and that introducing fiat currency into a commodity money economy may unambiguously improve welfare velocity acceptability and liquidity are discussed

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

place your bets towards an understanding of globalisation socio financial engineering and competition within a financial centre globalisation and technical change increase the intensity of competition within and between financial centres already subject to competitive pressures from an apparently highly mobile financial cap

bargaining and the value of money abstract search models of monetary exchange have typically relied on nash 1950 the bargaining problem econometrica 18 155 162 bargaining or strategic games that yield an equivalent outcome to determine the terms of trade by considering alternative axiomatic bargaining solutions in a search model with divisible money we show that the properties of the bargaining solutions do matter both qualitatively and quantitatively for questions of first degree importance in monetary economics such as i the efficiency of monetary equilibrium ii the optimality of the friedman rule and iii the welfare cost of inflation

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

pairwise trade and coexistence of money and higher return assets abstract a new theory of coexistence of money and higher return assets is set out it applies to any setting in which some trade involves an exchange of goods for assets and occurs between two people a buyer and a seller we show that there exists a function mapping the portfolios of the buyer and the seller to the trade that occurs such that i the trade is in the buyer seller core and ii some people are induced to enter the buyer seller meeting with money

search money and capital a neoclassical dichotomy recent work has reduced the gap between search based monetary theory and mainstream macroeconomics by incorporating into the search model some centralized markets as well as some decentralized markets where money is essential this paper takes a further step toward this integration by introducing labor capital and neoclassical firms the resulting framework nests a search theoretic monetary model and a standard neoclassical growth model as special cases perhaps surprisingly it also exhibits a dichotomy one can determine the equilibrium path for the value of money independent of the paths of consumption investment and employment in the centralized market

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

monetary policy and efficiency in over the counter financial trade we develop a monetary model that incorporates over the counter otc asset trade after agents have made their money holding decisions they receive an idiosyncratic shock that affects their valuation for consumption and hence for the unique liquid asset namely money subsequently agents can choose whether they want to enter the otc market in order to sell assets and thus boost their liquidity or to buy assets and thus provide liquidity to other agents a unique feature of our model is that inflation affects welfare not only through the traditional channel i e through determining equilibrium real balances but also through influencing agents entry decisions in the financial market we use our framework to study the effect of inflation on welfare asset prices and otc trade volume in contrast to most monetary models which predict a negative relationship between inflation and welfare we find that inflation can be welfare improving within a certain range because it mitigates a search externality that agents impose on one another when they make their otc market entry decision

pairwise trade asset prices and monetary policy abstract we construct a search theoretic model where fiat money coexists with real assets and all assets can be used as a media of exchange the terms of trade in bilateral matches are determined by a pairwise pareto efficient pricing mechanism we do not have to appeal to exogenous liquidity constraints to generate asset prices that are consistent with the following facts i fiat money can be valued despite being dominated in its rate of return ii real assets with identical dividend flows can have different rates of return and iii an increase in inflation raises asset prices lowers their returns and widens the rate of return differences between assets on the normative side we show that there is a range of inflation rates that implement the first best allocation

essential interest bearing money i examine optimal monetary policy in a lagos and wright a unified framework for monetary theory and policy analysis j polit econ 113 2005 463 484 model where trade is centralized and all exchange is voluntary i identify a class of incentivefeasible policies that improve welfare beyond what is achievable with zero intervention any policy in this class necessarily entails a non negative inflation rate and a strictly positive nominal interest rate despite the absence of a lump sum tax instrument there exists an incentive feasible policy that implements the first best allocation

liquidity provision interest rates and unemployment abstract the effective liquidity supply of the economy the weighted sum of all assets that serve as media of exchange matters for interest rates and unemployment we formalize this idea by adding an over the counter market with collateralized trades to the mortensen pissarides model an increase in public liquidity through a higher supply of real government bonds raises the real interest rate crowding out private liquidity and increasing unemployment if unemployment is inefficiently high keeping liquidity scarce can be socially optimal a liquidity crisis affecting the acceptability of private assets as collateral widens the rate of return difference between private and public liquidity also increasing unemployment
