The cost of capital,asset prices,and the effects of monetary policy

The primary objective of this paper is to study the interaction between monetary policy, asset prices, and the cost of capital. In particular, we explore this issue in a setting where individuals face idiosyncratic risk. Incomplete information also provides a transactions role for money so that monetary policy can be studied. In contrast to standard monetary growth models which focus on the transmission of monetary policy to the demand for capital goods, we incorporate a separate capital goods sector so that the supply response to monetary policy is taken into account. Consequently, in contrast to the standard monetary growth model, monetary policy plays an important role in investment activity through the relative price of capital goods. Moreover, different sources of productivity can affect the degree of risk sharing. Although the optimal money growth rate falls in response to an increase in productivity in either sector of the economy, monetary policy should react more aggressively to the level of productivity in the capital sector.     

NOMINAL BONDS AND INTEREST RATES*

In this article, I integrate the microfoundation of monetary theory with the model of limited participation to analyze the competition between nominal bonds and money. The market for government nominal bonds is centralized and Walrasian, whereas the goods market is modeled as random matches. The government imposes a legal restriction that requires all government goods to be purchased with money but not with bonds. By contrast, private agents can exchange between themselves with both money and bonds. I show that an arbitrarily small legal restriction is sufficient to prevent matured bonds from being a medium of exchange. I also analyze the effects of monetary policy with and without the legal restriction. Some of those effects differ significantly from traditional monetary models.     

Existence of a monetary steady state in a matching model: indivisible money

Existence of a monetary steady state is established for a random matching model with divisible goods, indivisible money, an arbitrary bound on individual money holdings, and take-it-or-leave-it offers by consumers. The background environment is that in papers by Shi and by Trejos and Wright. The monetary steady state shown to exist has nice properties: the value function, defined on money holdings, is strictly increasing and strictly concave, and the measure over money holdings has full support.     

Existence of a monetary steady state in a matching model: divisible money

Existence of a monetary steady state is established in a random matching model with divisible goods, divisible money, an arbitrary bound on individual money holdings, and take-it-or-leave-it offers by consumers. The monetary steady state shown to exist has nice properties: the value function, defined on money holdings, is strictly increasing and strictly concave, and the distribution over money holdings has full support. The approach is to show that the “limit” of the nice steady states for indivisible money, existence of which was established in an earlier paper, as the unit of money goes to zero is a monetary steady state for divisible money. For indivisible money, the marginal utility of consumption at zero was assumed to be large; for divisible money it is assumed to be large and finite.     

Search, money, and inflation under private information

I study monetary exchange and inflation when buyers have private information about their willingness to pay for certain goods. Introducing imperfect information in the Lagos-Wright [A unified framework for monetary theory and policy analysis, J. Polit. Economy 113(3) (2005) 463-484] economy shows that the existence of monetary equilibrium is a more robust feature of the environment. In general, my model has a monetary steady state in which only a proportion of the agents hold money. Agents who do not hold money cannot participate in trade in the decentralized market. The proportion of agents holding money is endogenous and depends (negatively) on the level of expected inflation. As in Lagos and Wright's model, in equilibrium there is a positive welfare cost of expected inflation, but the origins of this cost are very different.     

THE DISTRIBUTION OF MONEY AND PRICES IN SEARCH EQUILIBRIUM*

This article considers a search‐theoretic model of monetary exchange. Agents bargain over both the amount of money and the quantity of goods to be exchanged in bilateral meetings, determining endogenously the distributions of money and of prices. I show that money is neutral if changes in the money supply are accomplished via proportional transfers. However, within the class of lump‐sum transfers, an increase of the rate of monetary expansion tends to decrease the dispersion of wealth and prices and to improve welfare when inflation is low; but when inflation is high enough, the opposite effects occur.     

Asset-return anomalies in a monetary economy

This paper provides a general equilibrium, choice theoretic, spatial model which explains the preference for holding barren money rather than interest-bearing securities or capital goods. Put somewhat differently, it examines standard asset pricing relationships in the context of a fully articulated monetary economy and delivers various asset-return anomalies. In seeking to integrate the theory of value with the theory of money, a fairly general proof of the existence of a monetary equilibrium is provided.     

BALANCED BUDGETS: ECONOMIC NIRVANA OR FISCAL CHAOS?

This paper investigates the effect of a pay-as-you-go, balanced budget policy on macroeconomic performance. It uses a simple model of the aggregate demand for money and goods, with temporary monetary equilibrium and quantity adjustments on goods markets. Within this framework, if the monetary/real interaction is strong enough, a balanced budget with sufficiently high tax rates (≡ sufficiently high government expenditures) is consistent with typical bounded fluctuations around a relatively high income, low unemployment equilibrium. Lower tax rates (≡ lower government expenditures) can trigger a sharp decline in revenues, expenditures, employment, and output.     

Money and Information

This paper investigates the role of money in markets in which producers have private information about the quality of the goods they supply. When the fraction of high-quality producers in the economy is given, money promotes the production of high-quality goods, which improves the quality mix and welfare unambiguously. When this fraction is endogenous, however, we find that money can decrease welfare relative to the barter equilibrium. The origin of this inefficiency is that money provides consumption insurance to low-quality producers, which can result in a higher fraction of low-quality producers in the monetary equilibrium. Finally, we find that most often agents acquire more costly information in the monetary equilibrium than in the barter equilibrium. Consequently, money is welfare-enhancing because it promotes useful production and exchange, but not because it saves information costs.     

Existence of a continuum of equilibria in a monetary random-matching model

In this paper, we study a monetary random-matching model where both goods and money are perfectly divisible, production is costly, and there is no exogenous upper bound on agents' money holdings, information on which is private to the agent. We show that there is a continuum of stationary equilibria where agents have either no money or a set amount, and buyers spend all their money. As in the previous studies, the equilibrium value function is step-like, which emerges as a self-fulfilling prophecy. The endogenous upper bound on agents' money holdings is the result of private information on agents' money holdings. Buyers post an offer that is accepted only by sellers without money, who set a higher value on money.     

A Diagrammatic Exposition of the Monetary Trade Model

In recent literature the monetary model of trade is presented diagrammatically in terms of hoarding and of the relative price of non-traded goods. In this paper we go back to the original diagrammatic approach of Mundell where he uses the stock of domestic money instead of hoarding. We adapt Mundells approach to the more recent developments of the monetary model and point out its expository advantages. We conclude the paper with a comparison of the two approaches.     

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. In our model, inflation affects not only the money holding decisions of agents, as is standard in monetary theory, but also the entry decision of these agents 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. Also, an increase in the holding cost of money will lead to a decrease in asset prices, a regularity that is well documented in the data and often considered anomalous.     

Societal benefits of illiquid bonds

In this paper, I provide a possible explanation of why nominally risk-free bonds are essential in monetary economies. I argue that the role of nominal bonds is to enable agents to engage in intertemporal exchanges of money. I show that bonds can only serve this role if they are illiquid (costly to exchange for goods). Finally, I argue that in economies in which nominal bonds are essential, it is optimal for monetary policy to respond to changes in the distribution of liquidity needs.     

Limited participation,private money,and credit in a spatial model of money

Summary. The purpose of this paper is to explore the implications of private money issue for the effects of monetary policy, for optimal policy, and for the role of fiat money. A locational model is constructed which gives an explicit account of the role for money and credit, and for limited financial market participation. When private money issue is prohibited, there is a liquidity effect as the result of a money injection from the central bank, but this effect goes away when private money is permitted. Private money issue changes dramatically the nature of optimal monetary policy. With private money, fiat currency is no longer used in transactions involving goods, but currency and central bank reserves play an important part in the clearing and settlement of private money returned for redemption.Received: 5 May 2003, Revised: 1 December 2003JEL Classification Numbers: E4, E5.The author thanks seminar participants at the Federal Reserve Bank of Richmond and Duke University, conference participants at the Texas Monetary Conference at U.T.

Inflation dynamics in a small emerging market

This study investigates the determinants of inflation in the Dominican Republic during 1991 to 2002, a period characterized by remarkable macroeconomic stability and growth. By developing a parsimonious and empirically stable error correction model using quarterly observations, the study finds that inflation is explained by changes in monetary aggregates, real output, foreign inflation and the exchange rate. Long-run relationships in the money and traded goods markets are found to exist, but only the disequilibrium from the money market exerts a significant impact on inflation.     

国际储备积累、实物与资产价格通胀及货币政策独立性

本文理论模型显示,国际储备积累引起的货币增发会导致实物和资产价格上涨,降低货币政策独立性。首先,尽管货币政策工具短期内可以通过冲销和抑制信贷等方法控制通胀,但只要顺差积累足够大,长期无法阻止通胀。其次,如果人们预期央行未来会让物价上升,即使物价当前仍被较好地控制,资产价格也可能出现大幅上涨。最后,在"不可能三角"中,即使放弃资本自由流动,也并不意味着就能同时拥有汇率稳定和独立货币政策。     

A post‐Keynesian model of output,employment and monetary demand

This paper presents a simple model based on three broad Post‐Keynesian hypotheses: (1) the economic process develops over time; (2) money is endogenous; and (3) producers are price setters. To make the analysis easier we also assume (4) that firms are vertically integrated. Producers assess the expected demand and ask banks for credit in order to start production; banks create credit at the request of producers to finance the wage bill; workers buy goods sold by firms; firms must repay banks the amount borrowed plus interest and earn a target rate of profit. Since firms have created only as much purchasing power as they have advanced to workers in the form of the wage fund, equilibrium requires that there is an amount of autonomous monetary demand equal to profits and interest. Furthermore, in order to make the value of supply equal to the value of effective demand, firms will employ the number of workers necessary to create the purchasing power which, when added to the anticipated autonomous demand, enables all costs to be covered and the planned rate of profits to be attained.     

On Income Velocity of Money,Precautionary Money Demand and Growth

A stochastic growth model with money introduced via a cash-in-advance constraint is used to analyze the behavior of the income velocity of real monetary balances and money demand. Agents can purchase consumption goods only using government issued money. The cash-in-advance constraint may become nonbinding because of the uncertainty about the realization of the state of the economy. We find that the precautionary money demand may introduce significant changes into the volatility of the income velocity if it happens almost always. Its presence can also alter the relationship between the average growth rate of money supply and the average growth rate of the economy.     

Business cycle,interest rate and money in the euro area: A common factor model

In this paper we model and analyze the contemporaneous correlation between interest rate, monetary aggregates, production and prices (of consumer goods, financial assets and real estate) of the euro area. To do this, firstly we estimate a common cyclical factor by means of an unobserved component model with the common factor located in variations in the underlying growth rates, that is, accelerations and decelerations of the variables. The variables mentioned share a significant cyclical factor being all procyclical except for narrow money. Finally we offer an explanation of this empirical finding based on the monetary policy strategy of interest rate pegging followed by the European Central Bank. In this regard, the shared cyclical information suggests (a) that inflation should be considered as a phenomenon that affects the whole economy, and therefore all prices, and (b) that monetary indicators such as monetary aggregates may contribute to the assessment of inflationary risks throughout the cycle.     

Monetary policy under flexible exchange rates: When is expansion contractionary?

This paper studies whether the observed instability in the effects of monetary policy could be due to the way in which the behavior functions have been specified in an open economy context. Accordingly, special emphasis is on the specification of the behavior functions to correspond to their foundations in closedeconomy macrotheory. The demand for real money balances, in terms of the expenditure basket of goods, is specified as a function of income in terms of the same basket. Imports are specified as a function of expenditures, being functionally part of expenditures. The supply of labor is specified as a function of the expenditure price.It is shown that the exchange rate overshoots but output declines, to eventually rise above its original level in response to monetary expansion in the real wage model. In the money wage model, output and the exchange rate overshoot their steady-state levels if the expansion eventually leads to an increase in nominal wealth. If it leads to a decrease, both variables undershoot. However, if interest payments on foreign securities are not small relative to the trade balance, many of the effects are reversed. Thus the overshooting result is far from robust even in a standard model with an exogenous money supply.
