中国经济转型与货币需求

本文采用"从一般到特殊"的动态建模方法对中国经济转型过程中的货币需求函数进行了再估计,通过引入市场化进程相对指数作为衡量经济转型的制度变量考察货币需求、经济增长、通货膨胀、利率和经济转型之间的相互关系。结果发现,尽管1978—2007年间30年的改革开放使得中国的经济体制和金融体系发生了较大的转型,但通过引入适当的制度变量,仍然可以得到稳定的货币需求函数。本文建立的货币需求动态模型证实了经济体制的市场化转型无论长短期都是拉动货币需求增加的因素,通货膨胀是解释货币量的有效外生解释变量,短期内利率变量对实际货币需求影响不显著,但其确实显著地进入了长期货币需求关系。     

Analysing money demand relation for OECD countries using common factors

This article investigates the existence of a long-run money demand relation for a panel data consisting of 13 OECD countries. The analysis is based on the most recent data. The existence of a long-run money demand relation is tested with two new meta-analytic panel cointegrating rank tests which are robust to cross-sectional dependence. Cross-sectional dependency in the data generating process is modelled by unobserved common factors. The observed data are decomposed into idiosyncratic and common components, and these two components are analysed separately to find out the driving forces of the long-run stationary relationship. The evidence shows that the long-run money demand relation is driven by the cross-unit cointegration. Finally, the long-run relation is estimated by taking the common factors into account.     

Revisiting the US money demand function: an application of the Lagrange multiplier structural break unit root test and the bounds test for a long-run relationship

In this article, we examine the issue of a levels relationship and stability of the US money demand function over the period 1959:01 to 2004:02. We use the Lagrange multiplier structural break unit root test and the bounds testing approach to a long-run relationship in levels of the variables, namely real money demand, nominal interest rate and real income. We find greater evidence for a long-run relationship in levels and stability of the US money demand function when we use M2 as a proxy for money demand. However, we find little evidence for a long-run relationship between M1 and M2 with their determinants for the recent period, spanning the last decade or so.     

Financial Factors and the Empirical Behavior of Money Demand: A Case Study of Malaysia

The paper analyses the roles of financial factors in the behavior of M1 and M2 demands for Malaysia. The focus is on the possible changes in the elasticities of the M1 and M2 money demands in the environment of financial innovations and on the influence of real stock prices on the holdings of monetary assets. Our results reinforce existing studies that find the presence of the long-run M1 and M2 money demands and structural instability in the dynamic specification of the M1 demand. However, we are able to identify stable error-correction model for the post-1986 M1 demand and for the M2 demand. Our results also indicate the reduction in the Long run income and exchange rate elasticities of the money demands. Meanwhile, the interest rate sensitivity of the demands becomes more inelastic. Lastly, we document the significance of real stock prices in influencing the demand behavior, indicating the dominance of the wealth effect over the substitution effect. [E41, E44]     

Evidence on nonlinear error correction in money demand: the case of Taiwan

This paper proposes a nonlinear error-correction model based upon smooth transition regression methodology. The model is specified such that the short-run adjustment toward long-run equilibrium is nonlinear and that the error correction is a smooth function of long-run deviation. Empirical results obtained from estimating M2 money demand in Taiwan support the hypothesis of a nonlinear error-correction process and provide better interpretation of change in the demand for money.     

Monetary dynamics: a market approach

The behaviour of the short-run responses implied by the identification of a long-run money demand relationship is examined. These responses have recently been interpreted as representing the policy stance of the monetary authority. However, as movements in the monetary aggregate reflect both demand and supply adjustments, estimating the short-run dynamics solely within the money demand relationship may produce biased results. In order to address this issue, the paper explicitly acknowledges the importance of the supply of money function by including the function alongside the demand for money function. While the interaction of the two equations continues to produce the long-run quantity theory result, the additional detail provides more accurate estimates of the individual short-run adjustments within the two equations.     

Long-run estimates of money demand: new evidence from East Asian countries and the presence of structural breaks

Conventionally, the money demand function is estimated using a linear regression of the logarithm of money demand on a number of variables. In this article, we aim to estimate the long-run properties of money demand specification for a number of East Asian economies and within a panel framework with the presence of structural breaks. Various country-specific coefficients are allowed to capture inter-country heterogeneities. Consistent with theoretical postulates, it is found that (a) the demand for money in the long-run positively responds to real income and inversely to the interest rate spread, inflation, the real effective exchange rate and the US real interest rate; (b) the long-run income elasticity is greater than unity; and (c) both the currency substitution and capital mobility hypotheses hold. The empirical findings in this article can provide useful policy guidelines to the East Asian countries’ central banks in their quest for price stability. If one of the primary objectives of these countries is to minimize price instability, they should avoid creating unnecessary disequilibrium in the money market, while the employment of cointegration with the presence of structural breaks clearly recommends to central banks to use the supply of money to attain price and macroeconomic stability.     

Some further evidence on the long-run neutrality of money

A recently developed reduced-form test for long-run neutrality is applied to twentieth-century Australian data on real output and the nominal money stock. The results show that narrowly defined money is neutral. However, real output is not invariant in the long run to a broader-based measure of the money stock.     

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.     

Short-run and long-run demand for financial assets A microeconomic perspective

One of the major issues associated with the short-run aggregate money demand is that the speed of adjustment has become very slow or even negative when the post-1973 periods are included in regressions. This implies that the long-run effects of income, wealth, or the opportunity costs on money demand may be so large that a small change in any of these variables would lead to unreasonably large fluctuations in asset demand. Using microeconomic data from the Survey of Income and Program Participation conducted by the U.S. Bureau of the Census, this study finds that the speeds at which individuals adjust their actual quantities of financial assets toward the desired levels are actually quite fast. In the long run, there is no indication that the desired quantities of monetary assets fluctuate widely whenever an explanatory variable is disturbed.     

The demand for money in Austria

In this paper, the demand for real money M1, M2, and M3 is estimated for Austria over the time period 1965–96. The modelling takes place within the framework of a small vector autoregression. To estimate the demand for money, two-equation error-correction models are constructed, which contain the short-run dynamics and the long-run economic equilibrium. It is found that a stable money demand exists for all monetary aggregates. The long-run equilibrium of M1, after accounting for a structural break in 1979, can be characterised as a classical type of money demand, with no interest rate effects and an elasticity of one for real GDP. In the case of M2 and M3, we find a unit coefficient on income and a significantly negative influence of a long-term interest rate. The statistical properties of the estimated short-run money demand equations – considering in-sample and out-of-sample tests – are generally very good.

Do exchange rate changes have symmetric or asymmetric effects on the demand for money in Turkey?

As a result of the research conducted by Nobel Laureate Robert Mundell (1963), most studies estimating the demand for money today do include the exchange rate in their specification to account for currency substitution. Previous studies that did this for the Turkish demand for money assumed that exchange rate changes do have symmetric effects on the demand for money in Turkey. In this article, we question this assumption. By using the nonlinear ARDL approach, we show that indeed exchange rate changes do have short-run and long-run asymmetric effects on the M1 demand for money. Introducing nonlinearity also yields a stable money demand.     

Stock prices and long-run demand for money: evidence from Malaysia

This paper investigates the money demand function for Malaysia in the 1971-1996 period using the multivariate cointegration and error correction model methodology. The results suggest that a stable long-run relationship exist between real M2, the interest rate differential, income and stock prices. Stock prices have a significant negative substitute effect on long-run as well as short-run broad-money demand (M2) and its omission can lead to serious misspecification in the money demand function. The analysis from the vector error correction model (VECM) and the Toda & Yamamoto (1995) causality tests find that money is endogenous and that there is at least a unidirectional relationship between stock prices and real M2. Stock prices Granger cause real M2 indirectly through income between interest rates and stock prices and stock prices and money stock. This paper comes to the conclusion that due to the endogeneity of money, M2 cannot be completely controlled by Malaysia's central bank. Therefore, in formulating future monetary policy, the response of money demand to stock prices should be considered.     

Stability of money demand function revisited in China

As China's economic reforms have undergone significant structural changes after 1979, it has been rather difficult to formulate a stable money demand function over the period following that year. While previous literature on the long-run relationship of money demand in China shows the existence of stable money demand, this article revisits the stability of the China money demand function over the period after 1979. To employ the unit root tests and the cointegration tests with structural break, the empirical evidence demonstrates that economic and financial deregulation did affect the stability of demand for money in China over the period 1977 to 2002. Moreover, the estimated long-run income and interest elasticity are respectively 1.01 (1.11) and ?0.14 (?0.08) using the real M1 (M2) equation. In addition, real income and the interest rate are found to be weakly exogenous. We overall do find structural breakpoints mainly in 1980 and 1993, and they look to match clearly with corresponding critical financial and economic incidents.     

From the general to the specific: The demand for M2 in three European countries

This paper examines the demand for broad money in West Germany, the Netherlands and France. We give an exposition of and apply the “general to specific” econometric modelling methodology which has been successful in modelling the demand for money in the U.K. We find stable short-run demand functions for each of the three countries examined, using a consistent data base previously published by other researchers. Each of the estimated short-run equations has a long-run or steady-state solution which is consistent with economic theory. For West Germany and the Netherlands we find long-run income elasticities of unity, which constrasts with the results of earlier studies.     

Estimating money demand functions for South Asian countries

In this paper, we estimate a money demand function for a panel of five South Asian countries. We find that the money demand and its determinants, namely real income, real exchange rate and short-term domestic and foreign interest rates are cointegrated both for individual countries as well as for the panel, and panel long-run elasticities provide robust evidence of statistically significant relationships between money demand and its determinants. Our test for panel Granger causality suggests short-run causality running from all variables, except foreign interest rate, to money demand, and we find evidence that except for Nepal money demand functions are stable.      

Long-run money demand in OECD countries: what role do common factors play?

This article examines the long-run money demand function for 11 OECD countries from 1983Q1 to 2006Q4 using panel data. The distinction between common factors and idiosyncratic components using principal component analysis allows for the detection of cross-member cointegration and the determination as to whether national or international sources are responsible for the non-stationarity of money and its determinants. Indeed, the finding that the common factors are I(1) while the idiosyncratic components are I(0) indicates that cross-member cointegration may exist and non-stationarity in the variables is primarily driven by common international trends. Furthermore, it is found that the impact of income on money demand is positive, whereas it is negative for the interest rate, exchange rate and stock prices. Except for the income elasticity of money demand, all estimated long-run coefficients are larger for the common factors of the variables than for the variables themselves. This article provides evidence that the exchange rate is an important determinant of money demand, whereas the results for the stock prices are ambiguous. Finally, the results of a panel-based error-correction model suggest that several domestic money stocks converge to a common international equilibrium relationship between the common factors.     

On the Stability of Long-Run M2 Demand in Japan

In this study we examine the stability of long-run broad money demand in Japan. In contrast to previous studies of Japanese broad money demand, we use a series of tests designed specifically to test for structural instability in the presence of I(1) processes. According to these tests, the Japanese broad money demand function appears to be stable over a period of financial innovation and deregulation.

Learning to believe in nonrational expectations that support pareto-superior outcomes

I consider the prototype New Keynesian macroeconomic model with subjective demand expectations of firms. In this model the firms' objective demand is log-linear in their relative price. Firms believe that their demand curve is linear or log-linear in their absolute price. They estimate the parameters of this curve by least squares from past observations on prices and quantities. The wage rate either clears the labor market given firms' demand perceptions or is given in the short run and changes according to a linear Phillips curve. In either setup of the model the interplay between learning and price setting confirms the subjective model. Among the long-run equilibria are solutions at which the representative household attains a higher level of utility as compared to the rational-expectations outcome. If the supply of labor depends upon the real wage, money is not neutral.     

Asymmetric effects of exchange rate changes on the demand for money in Africa

In order to account for currency substitution, the exchange rate is included in the demand for money. More recent studies have demonstrated that exchange rate changes could have asymmetric effects on the demand for money or domestic currency. In this paper, we consider the experiences of 18 African countries and show that in most countries, indeed exchange rate changes have short-run asymmetric effects on the demand for money. However, short-run effects translate to long-run asymmetric effects only in a limited number of African countries.
