古典货币中性理论的逻辑

古典经济学家把经济体系分离成实体经济与货币经济两个体系,一部分是利用瓦尔拉斯的一般均衡理论解释的实体经济体系,另一部分是利用货币数量论解释的货币经济体系,两个体系受各自规律支配,独立运行,货币是中性的,这就构成了古典货币中性理论的基本逻辑。     

Cash-in-advance constraints in the diamond overlapping generations model: neutrality and optimality of monetary policies

This paper is a study of money in overlapping generations modelswith cash-in-advances constraints. We first offer a brief reviewof different features of the cash-in-advance constraint. Thenwe propose a general formulation and study the neutrality ofmoney. We show that both neutrality and equilibrium dynamicsdepend on the form of the cash-in-advance constraint. We thenshow that optimal intergenerational resources sharing can beimplemented through monetary transfers. Finally, we find thatthe Chicago Rule is implied by the optimal monetary.     

Portfolio modelling and growth in open economies

The standard BRANSON model is modified in a way which allows one to focus on the short term dynamics of foreign bonds markets, the money market and the stock market—or alternatively the oil market. This allows us to explain the dynamics of the exchange rate and the oil price within a portfolio choice model; also we identify critical expectation dynamics in a more conventional pricing approach to the oil market—expectations determine whether or not the oil market equilibrium is compatible with a stationary price or with sustained oil price inflation. Moreover, a straightforward innovative way to combine a portfolio approach with a growth model is developed. New results are obtained—through multiplier analysis—about the long term effects of changes in the savings rate, the process innovation rate, the product innovation variable and the money supply on the exchange rate and the stock market price; this raises many empirical issues. Finally, the analysis presented sheds new light on the global asset price dynamics in the context of the banking crisis.

The evolution of Hayek's thought on gold and monetary standards

Early in his career, Hayek viewed attempts to stabilize exchange rates by facilitating cooperation between central banks, with respect to their demand for gold, to be at odds with the fundamental mechanisms of the gold standard. He opposed proposals by Irving Fisher, Gustav Cassel, and Ralph Hawtrey that promoted stabilization of demand for gold and price levels as a next best option. Hayek viewed the nations that refused to devalue their currency after monetary expansion during wartime as complicit in degrading the international gold standard. In 1935 Hayek's emphasis began to change, his position sounding much like the arguments of Cassel and Hawtrey. Though he eventually gave up hope that the international gold standard would be reestablished, his later work on money provides theoretical underpinnings for systems that would promote the same sort of stability and predictability that the classical gold standard had provided.     

Vehicle currency pricing and its positive welfare consequences under optimal monetary policy

Using a two-country general equilibrium model, this paper analytically derives the possibility of positive welfare consequences of vehicle currency use in invoicing international trades. Such vehicle currency use is prominent in the data. The literature points out welfare loss under optimal monetary policy due to vehicle currency pricing relative to the flexible price equilibrium outcome, modeling only tradable goods. By introducing nontradable goods and their sector-specific productivity shocks, this paper provides a closed-form condition under which one country's welfare is higher under optimal monetary policy if its exports are invoiced with the other country's currency than if invoiced with its own currency, given that the other country's exports are invoiced with the producer's currency. That is, this paper derives a condition under which vehicle currency pricing is preferred by the nonvehicle currency country to producer currency pricing.     

The Monetary Policy Implications of Behavioral Asset Bubbles

I introduce behavioral asset pricing rules into a wider dynamic stochastic general equilibrium framework. Asset price bubbles emerged endogenously within the model. I find that in this model monetary policy rules that target the mispricing of the asset have a destabilizing effect; however, a monetary policy rule that targets deviations in the price of the asset from its trend can be welfare enhancing. Such a rule would also have the benefit of being straightforward to implement.     

Een onderzoek naar de invloed van monetaire factoren op het reële groeiproces in enkele traditionele theorieen van economische groei (I)

Summary With some exceptions — e.g., Tobin and Johnson — theorists have been looking for an explanation of economic growth in the real sector. This is the first of three successive papers on the problem of to what extent monetary phenomena influence the real variables in a process of economic growth.If one aims at adding a monetary sector to a real model of economic growth, the first thing to do is getting an exposition of the monetary theory which is most suitable for this purpose. The monetary theory used in this paper is based on Patinkin and Gurley and Shaw. The conditions under which money does not affect the real economic process are amply discussed. Only in very special cases money turns out to be neutral.In the two subsequent papers this monetary theory is used for an investigation into the impact of money on growth according to a neo-classical and a neo-keynesian model of economic growth.De schrijvers zijn dank verschuldigd aan talrijke leden van de wetenschappelijke staf van de Economische Faculteit te Groningen en aan de deelnemers van een economistenconferentie te Tilburg op 12 januari 1968 voor hun stimulerende opmerkingen bij de oorspronkelijke versie van dit werkstuk.     

Macro policy in the tropics: How sensible people stand

A model for macro policy analysis is set out, incorporating an inflation theory based on distributional conflict, output and current account adjustment mechanisms, and the money market. Classic structuralist results about contractionary devaluation and stagflationary monetary restriction are derived. Alternative closures of the model are considered — monetarism and external strangulation (or foreign exchange bonanzas) — and it is extended to deal with interest rate reform. Short-term stabilization issues are analyzed — monetary and fiscal policy, import quotas and export subsidies as opposed to devaluation, financial market complications, food subsidies and public sector pricing, and orthodox and heterodox anti-inflationary programs. Finally, medium-term processes of inflation, distribution and growth are described. An example of an irreversible contractionary shock which leads the economy from a distributionally favorable to an unfavorable steady state is presented.     

Explorations in monetary history: A survey of the literature

Monetary economists have long been interested in economic history as a laboratory for the testing of theory. This paper surveys recent work in monetary history within the context of the modern quantity theory of money and the new classical macroeconomics. Topics surveyed include the development of historical monetary statistics and the determinants of money supply and money demand; historical uses of Granger-Sims causality tests of the relationships between money, prices, and output; historical studies of the secular behavior of velocity; the Great Depression; financial crises; historical evidence for the long-run and short-run neutrality of money; and domestic and international aspects of monetary standards. Each topic surveyed concludes with an evaluation and an agenda for future research.     

The liquidity effect in a flexible-price monetary model

This paper examines the impact of macroeconomic policy shocksin a flexible-price dynamic stochastic general equilibrium (DSGE)model with money. Rather than adopting a money supply rule,monetary policy is modelled as a central bank using a simpleinterest rate rule (Taylor rule). Without assuming price stickinessor frictions in financial markets, this model is found to accountfor liquidity effects, generate higher persistence in outputand inflation, and capture the positive unconditional cross-correlationsrelating inflation and output.     

Money demand in the West African economic and monetary union - the problems of aggregation

Regional monetary integration, financial liberalisation andthe adoption of indirect policy instruments continue to changethe conditions for monetary policy in the West African Economicand Monetary Union (WAEMU). While the identification of a stablemoney demand relationship has become a crucial element for monetarypolicy, differences in economic behaviour between Côted'Ivoire and the remaining countries may induce instabilityat the aggregate level. This paper analyses the demand for moneyfor the entire WAEMU, the six smaller member countries, andCôte d'Ivoire. A stable aggregate money demand functionis identified and interpreted in light of the results for thesub-regional estimations.     

Monetary Shocks and the Fundamental Determinants of the Real Exchange Rate under the Hong Kong Currency Board

To assess the claim that flexible markets render monetary policy unimportant under the currency board, we test the impact of monetary shocks on Hong Kong's real exchange rate. Using vector autoregressions, we find persistent effects of monetary shocks on the real exchange rate, implying money is not neutral in Hong Kong. We then estimate the equilibrium real exchange rate, employing the definition developed by Rogoff-Obstfeld-Stein. The divergence between the observed and equilibrium rates is clearly stationary throughout the 1980s, but after a key policy shift in 1991 that divergence becomes non-stationary. We conclude that Hong Kong's real exchange rate moved away from the real fundamentals in the latter period.     

Causes of Inflation in China： Inflation Expectations

This paper argues that the main causes of inflation in China since the early 21st century are changes in the public's inflation expectations. The conventional wisdom, the quantity theory of money, may not be adequate to capture the relationship between price changes and money supply growth, as the economic system evolves and people's income and wealth grow. An examination of China's GDP deflator and broad money supply relative to nominal GDP shows that the relationship between the two series is relatively weak. A further examination of China's monthly CPI series over the period 2001–2010 reveals that the autoregressive models are a better fit than the moving average models, which suggests that the role of CPI expectations has been significant and important. Because of the importance of inflation expectations in CPI movement, we believe the Central Bank's monetary policy that targets CPI inflation should emphasize the use of policy instruments that have direct and strong communication links with the public. Quantitative measures would have their own use, but their effectiveness would be unlikely to match that of interest rate measures, especially from a short‐term perspective.     

Dynamic simulations on overshooting of flexible commodity prices with a modified arbitrage condition

Applying a Neo‐Keynesian approach, this study investigates whether in the short run flexible commodity prices overshoot their long‐run equilibrium whenever there is a monetary change. Two differential equations are generated depicting the adjustment paths for commodity prices and prices of manufactures. With a modified arbitrage condition that incorporates convenience yield, flexible commodity prices are shown to overshoot their long‐run equilibrium when compared with less‐flexible prices of manufactured goods. Simulation results support the breakdown of money neutrality in the short run. Inflation rate and degree of rigidity of prices of manufactures are shown to have a significant effect on the adjustment paths. Convenience yield did not influence the adjustment mechanism.     

The monetary exchange rate model in the long run: An empirical investigation

The Monetary Exchange Rate Model in the Long Run: An Empirical Investigation. — This paper uses the Johansen multivariate cointegration method to examine three variants of the monetary approach to the long-run exchange rate model: flexible price, forward-looking and sticky price monetary models. Evidence is provided for four bilateral sterling exchange rates. The sensitivity of the results to the measurement of monetary aggregates is also examined. The cointegration results provide dismal evidence for the flexible price and forward-looking models irrespective of the measurement of money. The findings are more mixed for the sticky price model, particularly when broad money is used.     

Monetarism: The issues and the outcome

The paper surveys some main issues in the monetarist-Keynesian debate of the 1960s and 1970s and the outcome of the debate. The debate was not static; the issues changed. At first Keynesians argued that money was largely irrelevant for output and the price level. By the end of the 1970s, issues such as neutrality, the natural rate, and the effect of inflation on nominal interest rates had been settled. Principal remaining issues were the use of money growth as a target, instrument, or indicator of monetary policy and reliance on rules. The paper sketches some of the progress on rules versus discretion in the past 20 years but focuses mostly on the role of money. Some evidence is presented for the U.S. supporting the monetarist position that control of money is useful in a medium-term or rule-based policy to control inflation as now advocated by several central banks.Distinguished Address presented at the Forty-Fourth International Atlantic Economic Conference, Philadelphia, Pennsylvania, October 9–12, 1997.

Does Money Have a Role in Monetary Policy for Price Stability under Inflation Targeting in Thailand?

This paper deploys Thai quarterly data for the study period 1999q1–2014q4 to econometrically investigate the proposition that money growth is an important, if not the sole, determinant of inflation under inflation targeting and that the money growth-inflation relation is not conditional on the stability of the money-demand function. The autoregressive distributed-lag (ARDL) bounds-testing results suggest that, across the study period, the Thai money stock (narrow or broad), real output, prices, interest rates and exchange rates maintained a long-run equilibrium relationship. The associated error-correction model of inflation confirms the cointegral relationship among money (narrow or broad), real output, prices, interest rates and exchange rates. It also suggests that money growth has a significant distributed-lag impact on inflation. The presence of this money growth-inflation relationship was associated with a stable narrow money-demand function, whereas the broad money-demand function remained unstable. These results for the study period are consistent with the view that the causal relationship between money growth and inflation holds in Thailand under inflation targeting when the Bank of Thailand deploys a short-term policy interest rate, rather than a monetary aggregate, as the instrument of monetary policy and that this relationship is not conditional on the stability of the money-demand function.     

Monetary theory and monetary policy a central banker's view

Summary In this article attention is paid to monetary theory, the relationship between the instruments of monetary policy and other important macro-economic policy instruments, and finally to the real possibilities of pursuing an effective monetary policy. The conclusion from the theoretical analysis is that the total money supply must be considered one of the most important macro-economic policy instruments. An excessive supply of money will sooner or later lead to inflation, to the debasement of money. Therefore the volume of money should be controlled. The use and effectiveness of monetary policy should always be seen in the context of other policy instruments, especially fiscal policy and, under circumstances, wage- and price policy. The possibilities to pursue an effective monetary policy are not unlimited. The effectiveness of such a policy can,e.g., be hampered by external factors. It is vital for a central bank to have the widest possible range of instruments at its disposal.
