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.     

Effects of financial innovations on the money demand function: a Canadian evidence

A money demand function for the Candian economy has been estimated to explore if recent financial innovations have caused any significant change in the structural relationship between the demand for money and its determinants. Two sets of estimation results have been analysed: the first set is obtained by estimating a standard money demand function for several overlapping sample periods and the other set is obtained by estimating a modified version which included a dummy or a ratchet variable to capture the effects of innovations. The estimated equations have been used to generate ex-post simulations and forecasts. The results suggest that innovations have displaced the money demand function in the early 1980s. It also appears that the incorporation of approriate innovation variables improves the predictive performance of the money demand function.     

Broad money demand and financial liberalization in Greece

This paper develops a constant, data-coherent, equilibrium correction model for broad money demand (M3) in Greece over 1976–1994. The aggregate M3 was targeteduntil recently, and current monetary policy still uses such aggregates as guidelines. In spite of financial innovation, financial liberalization, and large fluctuations in the inflation rate, the estimated model is remarkabli stable. Dynamics are important, with price and income elasticities being much smaller in the short run than in the long run. The model provides a better understanding of the portfolio consequences of financial innovation and the effects of monetary policy in Greece.The authors are staff economists in the Division of International Finance, Federal Reserve Board, Washington, DC 20551 USA, and the Research Department, International Monetary Fund, Washington, DC 20431 USA, respectively.

Currency demand,new technology,and the adoption of electronic money: Micro evidence from Japan

We estimate currency demand functions conditional on electronic money adoption with household-level survey data from Japan under an Instrumental Quantile Regression framework. Contrary to theoretical predictions, our results suggest that users of electronic money hold more currency than non-users.     

An empirical note on bond-yield uncertainty and the demand for money

This paper empirically tests the effect of bond-yield uncertainty on the demand for money, as implied by the capital theory approach to the demand for money, suggested by Friedman and Tobin. It is expected that the demand for money is affected not only by the yield on bonds (which are a substitute asset), but it also in increasing function of their risk. The empirical tests, which employ two alternative measures of uncertainty (mean of squared deviations from the average, and the mean of squared deviation from a predictor obtained by exponential smoothing) seem to support the Friedman-Tobin hypothesis.     

Currency substitution,inflation, and welfare

Currency substitution affects the mapping between social welfare and inflation by altering the underlying money demand function and influencing interest rates. In order to explore the essence of this effect, I build a model with working capital under which foreign currency is substituted with the less liquid components of domestic money. The framework closely mimics the actual pattern of currency substitution across varying rates of inflation and enables the study of an additional channel that works through the impact of currency substitution on interest rates. It is found that there is a threshold inflation rate, which turns out to be 44% under baseline calibration, below which currency substitution decreases welfare and vice versa. A practical implication is that, at inflation rates lower (greater) than the threshold, the potential welfare gains from disinflation to a near-zero inflation rate are higher (lower) if there is currency substitution than otherwise.     

A stable demand for money despite financial crisis: the case of Venezuela

The demand for broad money in Venezuela is investigated over a period of financial crisis and substantial exchange rate fluctuations. The analysis shows that there exist a long-run relationship between real money, real income, inflation, the exchange rate and an interest rate differential, that remains stable over major policy changes and large shocks. The long-run properties emphasize that both inflation and exchange rate depreciations have negative effects on real money demand, whereas a higher interest rate differential has positive effects. The long-run relationship is finally embedded in a dynamic equilibrium correction model with constant parameters. These results have implications for a policy-maker. In particular, they emphasize that with a high degree of currency substitution in Venezuela, monetary aggregates will be very sensitive to changes in the economic environment.     

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.     

The transactions demand for money in the presence of currency substitution: evidence from Vietnam

Currency substitution – the use of foreign money to finance transactions between domestic residents – is widespread in low income and transition economies. Traditionally, however, empirical models of the demand for money tend to concentrate on the portfolio motive for holding foreign currency, while maintaining the assumption that the income elasticity of demand for domestic money is invariant to the degree of currency substitution. A simple re-specification of the demand for money is offered which more accurately reflects the process of currency substitution by allowing for a variable income elasticity of demand for domestic money. This specification is estimated for Vietnam in the 1990s. Using a standard cointegration framework evidence is found for currency substitution only in the long-run but well-defined wealth effects operating in the short-run.     

Currency substitution,policy rule and pass-through: evidence from Turkey

In this article we analyse empirically currency substitution and exchange rate pass-through in the Turkish Economy, where their ongoing presence could undermine the implementation of a successful monetary policy, especially in a flexible exchange rate regime. Even though a considerable time has passed after the implementation of a flexible exchange rate regime in Turkey, by using Vector Error Correction model for the period from 1987 to 2004, we find that the currency substitution and exchange rate pass-through still have importance in the Turkish Economy and the monetary policy stance has been considerably strong, possibly, as a response of ongoing presence of them. If this is the case, to avoid the undesired consequences of this strong monetary policy, Turkey should consider some policy measures to reduce the degree of pass-through and currency substitution.     

Revisiting the demand for money model: money and loans in selected manufacturing industries

Using a dynamic infinite horizon optimizing model, it is shown that the empirical demand for money equation employed by a generation of applied monetary researchers is a reduced form model of the dynamic Euler equations for real money balances. The Euler equations derived in this paper focus on the finance capital for the firm and consist of real money balances (M1) and real business loans (F1) for selected manufacturing industries. By employing explicit structural dynamic specification and sectoral disaggregation, the question of how firms close the gap between desired real money balances and actual real money balances is examined. Model consistent ‘desired’ levels of money balances and business loans are found to depend not only upon the usual transactions variable and interest rate but also upon relative prices and a technology index. Moreover, the speed in closing the gap between desired and actual money balances (loan balances) is estimated using annual two-digit Standard Industrial Code data for durable and non-durable industries. Non-durable industries tend to close the gap faster than durable industries by as much as 25% in a given year.     

Currency substitution and seignorage in eastern europe

Economic and political uncertainty, high inflation and liberalization of foreign exchange restrictions have encouraged substantial currency substitution in the economies in transition. This paper presents empirical evidence on currency substitution in four Eastern European countries in transition: Poland, Hungary, Romania and Bulgaria. It is shown how currency substitution affects money demand and by that seignorage revenues. The empirical estimates of the money demand functions are used to calculate the seignorage maximizing rate of inflation in the economies in transition.     

Financial innovation and demand for money: some empirical evidence

Recent criticism of money growth targets has been based on the implications of spreading financial innovation, since the latter has been considered to undermine monetary policy effectiveness both by bringing about an increase in the interest elasticity of money demand and by producing instability of the money demand function. The empirical results presented in this paper – focusing on a single and specific case of financial innovation particularly suited to study the isssue at stake – falsify both hypotheses.     

Three decades of money demand studies: differences and similarities

Recent empirical contributions on procyclical productivity have focused on the dynamic implications of persistent aggregate fluctuations on sectoral productivity. Given a permanent innovation in aggregate output, unobserved variations of labour (or capital) utilization may have only a transitory effect on measured productivity, whereas external effects should produce permanent effects. It is found that persistent aggregate fluctuations have a permanent effect on productivity of four-digit US manufacturing industries. While a number of alternative explanations of this evidence are discussed and ruled out, the findings are consistent with a simple model with external or thick market effects.     

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.     

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.     

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.     

Timing, diffusion, and substitution of successive generations of technological innovations: The IBM mainframe case

Based on the behavioral assumptions of diffusion theory, this article proposes an extension of the Bass diffusion model that simultaneously captures the substitution pattern for each successive generation of a durable technological innovation, and the diffusion pattern of the base technology. Normative guidelines based on the model suggest that a firm should either introduce a new generation as soon as it is available or delay its introduction to a much later date at the maturity stage of the preceding generation. The decision depends on a number of factors including the relative size of the market potentials, gross profit margins, the diffusion and substitution parameters, and the discount factor of the firm. This “now or at maturity” rule is thus an extension and generalization of the “now or never” rule of Wilson and Norton [25]. Empirical and normative implications of the proposed model are explored for four successive generations on IBM mainframe computers: first generation (vacuum tubes); second generation (transistors); 360 family (integrated circuits); and 370 family (silicon chips). The model describes the growth of these generations well. The application of normative guidelines suggests that IBM introduced the two successive generations of 360 and 370 families too late, i.e., their time to market should have been shorter. Limitations and further extensions of the model and the application are discussed.     

Rational expectations and the demand for money: A nonparametric approach

This paper tests the U.S. demand for money for evidence of the effect of rational expectations of the income and interest rate variables that enter as arguments into that function. The data employed are simple-sum and Divisia aggregates, and the nonparametric tests are of the identification and information orthogonality of the various monetary measures. The Akaike Criterion is used to distinguish among the alternative specifications. While non-rationality is the typical result, Divisia aggregates appear to be more “rational” than simple sum. There is evidence of mean-reversion in interest rates as well.     

A panel data approach to the demand for money and the effects of financial reforms in the Asian countries

Alternative panel data estimation methods are used to estimate the cointegrating equations for the demand for money (M1) for a panel of 14 Asian countries from 1970 to 2005. The effects of financial reforms are analyzed with estimates for two sets of sub-samples and two break dates. Our results show that money demand function has been stable and financial reforms are yet to have any significant effects. Since there is no evidence for instability in the demand for money, the central banks of these countries should use money supply, instead of the rate of interest, as the monetary policy instrument.
