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.

Ideology, markets and money

Contemporary economic theory is considered in terms of the science/ideologydistinction. Marx's critique of Hegel is then used to derivea demarcation criterion that sharply separates scientific knowledgefrom ideology. This critique interprets Hegelian methodologyas fundamentally ideological because it understands realityin terms of abstract thought and then hypostatises that thoughtas reality. This process is more generally treated in termsof Marx's theory of value and money, in which money really doesdo what Hegelian logic purports to do. The consequences of consideringMarxian theory in this way provide some purchase on the logicand limitations of contemporary economic theory.     

Endogenous money,inflation, and welfare

This paper addresses the classic question: what are the welfare costs of inflation. We employ a model in which the ratios of currency to deposits and currency to reserves are endogenously determined. The model distinguishes quantitatively between three sources of welfare cost of inflation, and provides further estimates for potential welfare gains from improvements in transaction technologies. Estimates of the marginal cost of public funds associated with the inflation tax are compared both with that of labor taxation within the model and with those reported in the public finance and macro literature. We conclude that not only is inflation an inefficient source of government revenue, but also that, in the absence of lump-sum taxation, deflationary policies may be highly inefficient.     

Tournaments, minimum wage, and money non-neutrality

To reconstruct the micro-foundation of Keynesian macro-economics, the efficiency wage theory has generally been considered a success in providing a plausible explanation for the existence of involuntary unemployment. However, little has been said about how monetary policy causes fluctuations in aggregate employment and output in the efficiency wage theory. This paper extends Lin and Yang’s [Econ. Inq. 39 (2001) 644] shirking-type efficiency wage model with tournaments to account for money non-neutrality. A distinct feature of our model is that, due to the adoption of tournaments, there will be a hierarchical wage structure rather than a flat wage in the economy. As will be argued, the labor market characterized in this paper is in a sense a reversion to Keynes’ General Theory, but also an improvement upon it.     

Disequilibrium macroeconomics, money as a buffer stock and the estimation of money demand

Standard explanations of the seeming instability of the money demand in the post-1973 period usually link to stories about financial innovation and deregulation. I propose an alternative hypothesis: Much of the seeming instability occurs because of shifts in monetary policy, either explicit or implicit, in an environment where the Federal Reserve controls a more “exogenous” money stock. My econometric analysis modifies existing methods for estimating markets in disequilibrium and incorporates newly developed cointegration and error-correction modeling. My findings provide support for the buffer-stock interpretation of the money market.     

Community banks,money and labour productivity

Does money affect productivity? We examine whether bank deposits, a measure of the money supply that excludes currency in circulation, influence labour productivity. Banks deposits are special in that they facilitate transactions and, in aggregate, add liquidity and credit availability to a region. By exploiting the distribution of community bank deposits across the states, we test the hypothesis that money is an input to the production function under a variety of panel data methods. We find evidence that bank transaction deposits and total deposits along with other production function inputs such as wages, labour and gross state product are cointegrated across the states; however, the economic contribution of money to labour productivity appears limited.     

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.     

Currency substitution, portfolio diversification, and money demand

Abstract .  We extend the Thomas (1985) dynamic optimizing model of money demand and currency substitution to the case in which the individual has restricted or no access to foreign currency denominated bonds. In this case currency substitution decisions and asset substitution decisions are not separable. The results obtained suggest that the significance of an expected exchange rate depreciation term in the demand for domestic money provides a valid test for the presence of currency substitution. Applying this approach to six Latin-American countries, we find evidence of currency substitution in Colombia, Dominican Republic, and Venezuela, but not in Brazil and Chile.     

Synthetic money

This paper provides a methodology for constructing synthetic money, which is defined as an optimal currency basket that mimics a single currency. Empirical evidence is provided by constructing a synthetic dollar from a currency basket comprised of six currencies that excludes the U.S. dollar. We believe that synthetic money has a number of practical applications, including currency pegging operations by nations, denomination of global bond issues by large firms and countries, and analyses of currency movements over time by interested parties.     

Taxation,rational expectations,and the neutrality of money

When progressive taxation of nominal income is introduced into a Barro-type monetary model with rational expectations, money may not be neutral even in the long run. In the short run, unanticipated money changes may cause output and prices to move either in the same or in opposite directions. The implications of this model are consistent with both the traditional inflation-output trade-off and the more recent phenomenon of “stagflation.”     

My money or yours: house money payment effects

This paper reports the results of an experiment designed to study how subjects’ decision making may be affected by the timing of participation payments (or show-up fees). The experiment follows Davis et al. (J. Econ. 30:69–95, 2004) where subjects were asked to make a sequential purchase decision and were given the opportunity to purchase information about the value of a good prior to a decision to purchase the good itself. There, subjects purchased information less often than expected which was interpreted as risk-seeking behavior. Here, we test a payment hypothesis by varying the timing of the participation payment. Payment of a show-up fee before the decision-making stages of the experiment increases information purchase, which we interpret as an increase in risk-averse behavior.     

Essential interest-bearing money

I examine optimal monetary policy in a Lagos and Wright [R. Lagos, R. Wright, A unified framework for monetary theory and policy analysis, J. Polit. Economy 113 (2005) 463-484] model where trade is centralized and all exchange is voluntary. I identify a class of incentive-feasible 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.     

Bidding for money

We analyze monetary exchange in a model that allows for directed search and multilateral matches. We consider environments with divisible goods and indivisible money, and compare the results with those in models that use random matching and bilateral bargaining. Two different pricing mechanisms are used: ex ante price posting, and ex post bidding (auctions). Also, we consider settings both with and without lotteries. We find that the model generates very simple and intuitive equilibrium allocations that are similar to those with random matching and bargaining, but with different comparative static and welfare properties.     

Optimal divisibility of money when money is costly to produce

There is wide agreement that currency was not available in conveniently small denominations prior to the 19th century. Here, estimates of the costs of providing and maintaining money (coins) in 15th century Europe and parameterized versions of a matching model of money are used to find the optimal degree of divisibility. Although the optima are sensitive to the specification of the matching model, the optimal sizes we find agree in order of magnitude with the sizes of the most common coins in 15th century Europe.     

The spirit of capitalism, social status, money, and accumulation

This paper demonstrates the unambiguous existence of the Tobin portfolio-shift effect in the wealth-is-status and the spirit-of-capitalism models of growth. Namely, higher inflation leads to higher capital stock in the long run, and inflation increases the endogenous-growth rate of the economy.
