monetary policy asset prices and liquidity in over the counter markets we develop a model where agents can allocate their wealth between a liquid asset which can be used to purchase consumption goods and an illiquid asset which represents a better store of value should a consumption opportunity arise agents may visit a frictional over the counter secondary asset market where they can exchange illiquid for liquid assets we characterize how monetary policy affects both the issue price and the secondary market price of the asset we also show that in contrast to conventional wisdom search and bargaining frictions in the secondary asset market can improve welfare if inflation is low

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

money credit and banking in monetary models where agents are subject to trading shocks there is typically an ex post inefficiency since some agents are holding idle balances while others are cash constrained this problem creates a role for financial intermediaries such as banks who accept nominal deposits and make nominal loans in general financial intermediation improves the allocation the gains in welfare come from the payment of interest on deposits and not from relaxing borrowers liquidity constraints we also demonstrate that when credit rationing occurs increasing the rate of inflation can be welfare improving

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

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

efficient monetary allocations and the illiquidity of bonds abstract we construct a monetary economy with heterogeneity in discounting and consumption risk agents can insure against this risk with money and nominal government bonds but all trades must be monetary we demonstrate that a deflationary policy a la friedman cannot sustain the constrained efficient allocation as no arbitrage imposes too stringent a bound on the return money can pay the constrained efficient allocation can be sustained when bonds have positive yields and under certain conditions only if they are illiquid illiquidity meaning that bonds cannot be transformed into consumption as easily as cash is necessary to eliminate arbitrage opportunities due to disparities in shadow interest rates

search bargaining money and prices the goal of this paper is to extend existing search theoretic models of fiat money which until now have assumed that the price level is exogenous by explicitly incorporating bilateral bargaining this allows us to determine the price level endogenously and leads to additional insights concerning the role of money for example we find that monetary equilibria are generally inefficient in the sense that output and prices differ from the solution to a social planner s problem although the difference can become small as the discount rate or search friction vanishes we also find that there exist nonstationary inflationary equilibria

money and collateral this paper presents a model in which money and collateral are both essential and complement each other as media of exchange the model has implications for asset prices output in ation and monetary policy both in steady state and

the returns to mobility and job search by gender using data from the national longitudinal survey of youth the authors estimate the returns to job search mobility and the interaction of search and mobility for young men and women they find st

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

money and asset prices with uninsurable risks abstract we present a theory of differences of liquidity across assets based on an endogenous ranking of assets as media of exchange arising from their relative quality as hedging devices when assets have two distinct roles as intertemporal media of exchange and hedging devices buyers have generically a strict preference for paying sellers with the asset which is the relative better hedging device for sellers the consequence of this preference is that there are three monetary policy regimes and these regimes differ in which assets serve as media of exchange whether assets carry a liquidity premium and in the impact that monetary policy has on asset prices

money and credit redux do we need both money and credit in models with explicit roles for payment instruments we show the answer is no if credit is easy money is useless if credit is tight money can be essential but then credit is irrelevant and changes in debt limits are neutral real balances respond endogenously to leave total liquidity constant this is true for exogenous or endogenous policy and debt limits secured or unsecured credit and fairly general preferences and pricing mechanisms while we also show how to overturn some results the benchmark model suggests credit conditions matter less than some people think

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 asset prices and the liquidity premium this paper examines the effect of monetary policy on the liquidity premium i e the market value of the liquidity services that financial assets provide to guide the empirical analysis i set up a monetary search model in which bonds provide liquidity services in addition to money the theory predicts that money supply and the nominal interest rate are positively correlated with the liquidity premium but the latter is negatively correlated with the bond supply the empirical analysis over the period from 1946 and 2008 confirms the theoretical findings this indicates that liquid bonds are substantive substitutes for money and the opportunity cost of holding money plays a key role in asset price determination the model can rationalize the existence of negative nominal yields when the nominal interest rate is low and liquid bond supply decreases

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

the societal benefit of a financial transaction tax we provide a novel justification for a financial transaction tax for economies where agents face stochastic consumption opportunities a financial transaction tax makes it more costly for agents to readjust their portfolios of liquid and illiquid assets in response to liquidity shocks which increase both the demand for and the price of liquid assets the higher price improves liquidity insurance and welfare for other market participants we calibrate the model to u s data and find that the optimal financial transaction tax is 1 6 and that it reduces the volume of financial trading by 17

credit frictions and participation in over the counter markets abstract this paper formalizes a nash bargaining game between two players constrained by capacity decisions made prior to entering the negotiation in equilibrium strategic interactions drive capacity choices to zero and shut trade down despite the existence of gains from trade the game is embedded in a general equilibrium model of decentralized asset trade with credit frictions to investigate the interaction between availability of credit and investors participation modeled through their choices of inventory and payment capacity partial access to credit is sufficient to restore trade the strategic interactions between payment capacity and inventory generate endogenous heterogeneity in holdings trade sizes and prices and complementarity between money and credit

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

rehypothecation and liquidity abstract we develop a dynamic general equilibrium monetary model where a shortage of collateral and incomplete markets motivate the formation of credit relationships and the rehypothecation of assets rehypothecation improves resource allocation because it permits liquidity to flow where it is most needed the liquidity benefits associated with rehypothecation are shown to be more important in high inflation high interest rate regimes regulations restricting the practice are shown to have very different consequences depending on how they are designed assigning collateral to segregated accounts as prescribed in the dodd frank act is generally welfare reducing in contrast an sec15c3 3 type regulation can improve welfare through the regulatory premium it confers on cash holdings which are inefficiently low when interest rates and inflation are high

institutions and the long run impact of early development we study the role of institutional development as a causal mechanism of history affecting current economic performance several indicators capturing different dimensions of early development in 1500 ad are used to remove the endogenous component of the variations in institutions these indicators are adjusted with large scale movements of people across international borders using the global migration matrix of putterman and weil 2010 to account for the fact that the ancestors of a population have facilitated the diffusion of knowledge when they migrate the exogenous component of institutions due to historical development is found to be a significant determinant of current output by demonstrating that the relationship between early development and current economic performance works through the channel of institutions and that better institutions can be traced back to historical factors the results of this paper shed some light on how history has played a role in shaping long run comparative development

liquidity and asset market dynamics this study analyzes economies with an essential role for liquid assets in the exchange process the model can generate multiple stationary equilibria across which asset prices market participation capitalization output and welfare are positively related it can also generate a variety of nonstationary equilibria even when fundamentals are deterministic and time invariant including periodic chaotic and stochastic sunspot equilibria with recurrent market crashes some equilibria have asset price trajectories that resemble bubbles growing and bursting endogenous private and public liquidity is also introduced sometimes it is efficient to provide enough liquid assets to satiate demand other times it is not

the role of trading frictions in financial markets abstract we develop a dynamic general equilibrium model to analyze the role of trading frictions in over the counter markets in our model agents face idiosyncratic preference shocks and a financial market allows them to rebalance their portfolio composed of money and bonds in response to these shocks we disentangle the effects of search and bargaining on welfare and study each one of them we show that bargaining is generally welfare improving while search frictions are not this is because search frictions do not only affect the demand for the respective assets but also their allocation

degreasing the wheels of finance can there be too much trading in financial markets we construct a dynamic general equilibrium model where agents face idiosyncratic liquidity shocks a financial market allows agents to adjust their portfolio of liquid and illiquid assets in response to these shocks the optimal policy is to restrict access to this market because portfolio choices exhibit a pecuniary externality agents do not take into account that by holding more of the liquid asset they not only acquire additional insurance against these liquidity shocks but also marginally increase the value of the liquid asset which improves insurance for other market participants

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

liquidity and asset prices a new monetarist approach abstract when lenders cannot force borrowers to repay debts assets are often pledged to secure loans in this paper borrowers lose collateral once they renege on debts and exclusion of defaulters occurs probabilistically with a higher probability implying better enforcement increased efficiency in enforcement reduces asset prices while raising loan to value ratios if the rise in loan to value ratios is the dominant effect aggregate liquidity and output increase with the advance in enforcement inflation raises the repayment cost by increasing the loan rate while raising the default cost through exclusion consequently inflation raises loan to value ratios and output only when enforcement is sufficiently efficient

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

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

asset liquidity and indivisibility abstract we study asset liquidity in a search theoretic framework where divisible assets can facilitate exchange for an indivisible consumption good the distinctive characteristics of our theory are that the asset dividend can be either positive or negative and buyers can choose whether or not to carry the asset and trade for the indivisible good buyers participation determines the demand for asset liquidity thus the asset price carries a liquidity premium component which reflects the function of the asset in facilitating trade the economy features multiple equilibria when the asset dividend is negative due to the trade off between the probability of trade and the endogenous cost of holding assets

outside versus inside bonds a modigliani miller type result for liquidity constrained economies when agents are liquidity constrained two options exist sell assets or borrow we compare the allocations arising in two economies in one agents can sell government outside bonds and in the other they can borrow by issuing inside bonds all transactions are voluntary implying no taxation or forced redemption of private debt we show that any allocation in the economy with inside bonds can be replicated in the economy with outside bonds but that the converse is not true however the optimal policy in each economy makes the allocations equivalent

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

frictional asset reallocation under adverse selection abstract this paper studies asset reallocation in over the counter markets subject to search bargaining and information frictions and discusses their implications for optimal monetary policy the results show that inefficiencies arise from trade under private information resulting in reduced trading volume and consumption conditional on search frictions in the over the counter market information frictions can be both welfare decreasing and welfare increasing addressing the pecuniary externality arising from the portfolio choice of liquid and illiquid assets optimality is guaranteed under the friedman rule away from the friedman rule efficiency can be restored through open market operations exchanging information sensitive assets for risk free bonds as conducted by the federal reserve in response to the global financial crisis

money and prices a model of search and bargaining abstract this paper makes commodities divisible and incorporates bargaining into the search theoretic model of money to determine the purchasing power of money or price it is shown that two monetary equilibria always coexist where fiat money is universally accepted the two equilibria differ in price output welfare and the velocity of money sunspot monetary equilibria exist in which money is universally accepted in all states of the economy multiplicity has novel implications on the effectiveness of currency substitution and exchange market intervention journal of economic literature classification numbers c78 e40

search based models of money and finance an integrated approach many applications in monetary economics of search and bargaining theory use shi trejos wright hereafter stw many applications in finance use duffie g rleanu pedersen hereafter dgp these models share several features and both concern liquidity yet they also differ in stw agents use assets as payment instruments when trading goods in dgp they pay with goods or transferable utility when trading assets we integrate the two this clarifies connections between the literatures and generates novel insights several new results are provided for the baseline stw and dgp models while the integrated structure generates even more interesting outcomes including endogenous transactions patterns and belief based dynamics

the optimal quantity of money and partially liquid assets abstract in a monetary economy a la williamson 2012 in which a competitive financial sector insures agents facing idiosyncratic liquidity risk on interest bearing assets we introduce a competitive market for liquidity reallocation and study optimal policy we show that at any inflation rate above the friedman rule the market is a welfare improving risk sharing mechanism over williamson s 2012 deposit contract the optimal policy requires real asset scarcity which increases the demand for money and shrinks consumption inequality between asset and money users also we demonstrate that the equilibrium deposit contract with re trading opportunities in the asset market replicates the market allocations

a tractable model of indirect asset liquidity abstract assets have indirect liquidity if they cannot be used as media of exchange but can be traded to obtain a medium of exchange money and thereby inherit monetary properties this essay describes a simple dynamic model of indirect asset liquidity provides closed form solutions for real and nominal assets and discusses properties of the solutions some of these are standard assets and money are imperfect substitutes asset demand curves slope down and money is not always neutral other properties are more surprising prices are flexible but appear sticky and an increase in the supply of indirectly liquid assets can decrease welfare because of its simplicity the model can be useful as a building block inside a larger model and for teaching concepts from monetary theory

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

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
