General equilibrium, markets, macroeconomics and money in a laboratory experimental environment

Summary. This paper reports on the use of laboratory experimental techniques to create relatively complete economic systems. The creation of these market systems reflects a first attempt to explore the nature of inherently interdependent environments and to assess the ability of simultaneous equations equilibrium models like the classical static general competitive equilibrium model, to predict aspects of system behaviors. In addition, the impact of the quantity of a fiat money was studied. The economies were successfully created. Classical models capture much of what was observed.

General equilibrium, markets, macroeconomics and money in a laboratory experimental environment

Summary. This paper studies a version of war of attrition where two agents with private information make irreversible investment decisions in continuous time. It analyzes a monotone equilibrium where the amount of delay in the timing of decisions is a monotone function of the strength of ones private signal: an agent with a clear signal makes a prompt decision, whereas an agent with a weak signal delays a decision to gather more information from the move of the other agent. Equilibrium delay is characterized under different assumptions about the number of investment options available.Received: 4 October 1996, Revised: 16 May 1997, JEL Classification Numbers: C72, D82, L13.Masaki Aoyagi: I am very grateful to an anonymous referee of this journal for helpful comments.

Currency substitution,financial innovations and money demand: a note

This note presents some Finnish evidence on the importance of currency substitution and financial innovations for money demand. It is also shown that conventional demend for money specifications which do not take these factors into account are clearly misspecified and produced unreasonable results. The problem is particularly acute for narrow concepts of money.     

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.     

Financial innovation,depository-institution deregulation,and the demand for money

Our hypothesis is that financial innovation and depository-institution deregulation explain much of the seeming instability in the post-1973 money demand. Following a procedure similar to that employed by Hafer and Hein (1982) and Hafer (1982), we conclude that money demand experiences three periods of gradual intercept drift—two down and one up—rather than several one-time shifts. The gradual intercept drift is consistent with our hypothesis of financial innovation and depository-institution deregulation. Furthermore, after accounting for the gradual drift, the resulting full-sample regression are well-behaved.     

Consumer expenditure,the demand for money,and the Hall hypothesis

Although a considerable amount of work has been conducted on the validity of the Hall hypothesis, as applied to consumer expenditure, there has been negligible empirical work on the Hall hypothesis as applied to the demand for money. In this paper the Hallian hypothesis is applied to consumer expenditure and the demand for money using quarterly data for six countries.     

Relative prices and the demand for money

This paper examines the validity of the conventional specification of money demand with particular reference to the issue of relative prices. It is shown that the conventional money demand function is based on the assumption of weak separability of money from commodities, which forms the basis for the absence of relative prices in money demand. Empirical and presumptive evidence suggests that weak separability is not tenable, implying that relative prices are important in money demand. The inclusion of commodity prices in money demand significantly affects the interest and income elasticity estimates. Finally, it is noted that the aggregate consumption function excluding commodity prices also has no theoretical and empirical base.     

Leakages from the money demand function

The performance of alternative scale variables is explored in a simple demand function for narrow money. Sequential test establish consumers' expenditure as the preferred measure. The implications for fiscal policy and the paradox of thrift are outlined.     

Permanent prices,expected price changes,and the demand for money

This paper investigates the empirical validity of the distinction between measured and permanent prices for cash balance decisions. The use of permanent prices has been advocated by Friedman over twenty five years ago, but the idea has received little attention in the literature. Using Canadian quarterly data, we find that the permanent price hypothesis yields meaningful estimates of the demand for money, but it does not appear to contribute significantly to our understanding of cash balance decisions. A number of assumptions about the relationship between the elasticities of income, price, and price change expectations are tested as well.     

Empirical modeling of money demand

This paper examines several central issues in the empirical modeling of money demand. These issues include economic theory, data measurement, parameter constancy, the opportunity cost of holding money, cointegration, model specification, exogeneity, and inferences for policy. Review of these issues at a general level is paralleled by discussion of specific empirical applications, including some new results on the demand for narrow money in the United Kingdom.The author is a staff economist in the Division of International Finance, Board of Governors of the Federal Reserve System, Washington, DC 20551 USA, and may be reached on the Internet at ericsson@frb.gov.

Cointegration,error correction and the demand for money in Cyprus

This paper applies the recently developed technique of cointegration to estimate the demand for broad money in the case of Cyprus. Cyprus is an example of a country which does not have a sophisticated financial sector and which faced a severe political shock at a certain point in her history. The hypothesis of instability in the demand for money function cannot be rejected if the effects of this shock are not taken into account. In particular, it is argued that there was a once and for all increase in the income elasticity of this function at the time of the shcock. When this shift is accounted for by the introduction of an appropriate variable in the cointegrating regression the hypothesis of instability in the demand for money is rejected. Two dynamic error correction models are then specified with income and consumption as the scale variables respectively. Non-nested tests are carried out which reveal that consumers' expenditure is a more appropriate scale variable than GDP.     

Economic uncertainty,monetary uncertainty and the Korean demand for money

Economic uncertainty and monetary uncertainty are said to affect public’s holding of money in either direction. In this paper, we consider the Korean demand for money, and after including two GARCH-based measures of output uncertainty and monetary uncertainty, we show that both measures exert significant effects on the demand for money in Korea in the short run. However, only the adverse effects of output uncertainty lasts into the long run. Indeed, including the two uncertainty measures yield a stable demand for money in Korea.     

Credit cards and aggregate money demand

This paper attempts to assess the effect of the growth in the use of credit cards upon aggregate household money holdings. In an inventory theoretic structure, when individuals have the choice of whether to use a credit card as an alternative means of payments, and with a given income distribution, the aggregate money demand relation is derived. It is shown that the existence of an alternative means of payment changes the predictions on the relevant elasticities from the standard model, and makes them variable over time, and gives some indication of how credit card growth causes shifts in aggregate money demand.     

Specification and Goldfeld money demand function

Despite intensive investigation of the temporal stability of the Goldfield formulation of the money demand function, a clear consensus on its stability has yet to emerge. This paper builds a statistical case supporting the first difference of log-levels specification, as opposed to the more commonly used log-levels specification, of the Goldfeld equation and then examines the stability of both specifications. Formal stability tests proposed by Cooley and Prescott, Farley and Hinich, and Brown, Durbin, and Evans are employed; the out-of-sample predictive performance is examined as well. These tests strongly support the first difference specification over thelog-levels specification.     

On the short-run and long-run demand for money

This paper makes precise the relationships between short-run and long-run demand for money, using methods commonly employed in growth models. It estimates these demand functions with quarterly French data and tests the validity in France of the modern version of the quantity theory of money. The effects of inflation on the demand for money are studied both in the short run and the long run. The speed of adjustment of money balances towards their long-run level is measured.     

Distribution effects and the business demand for money

This paper examines whether and how changes in an industry's firm-size distribution affect the per-firm demand for money. The size distribution of an industry potentially affects the demand for money through several channels. We examine four of those channels: 1) economies of scale; 2) decentralization in cash management; 3) cost of credit; and 4) compensating balances. We conclude that increasing the size inequality increases the industry's per-firm demand for money.     

Inflation and the demand for money in Israel

This paper examines the impacts of rational-price expectations and foreign-exchange reform, in addition to adaptive-price expectations, on money-demand in Israel. The regression results are used to determine the upper limit on the amount of seigniorage.     

The money demand function in a small,open and quasi-monetary economy: the Gambia

The open-economy money demand asserts that for its underlying theory to hold, the variables ought to be co-integrated. Co-integrated variables although nonstationary in level, can share a long-term trend that is indeed stationary. However, the open money demand model has mainly been tested in developed and developing nations. This article investigates the co-integrated open-economy money demand in the Gambia where the macro economy is a quasi-monetary system, small (relative to the world market), but very open with a floating exchange rate regime. In the co-integrated space, the Gambian money demand appears to be quite responsive to domestic income, a measure of interest rate and the real exchange rate fluctuations.
