A suggested reformulation of the theory of optimal currency areas

In contrast to conventional analyses of monetary union between two particular countries or sets of countries, this paper treats the possible expansion of a given currency area as a continuous variable ranging from zero to one; zero if there is no expansion and one if all sources of imports and competition in trade are included in the union. The optimal order in which new members are admitted to the union then becomes a central aspect of the problem. Along with other advantages, this approach makes it easier to defend the argument that many nations are too small for form optimal currency areas. The demands upon the origin of the shocks, factor mobility, and political organization are smaller.     

The spill over effects of monetary policies and the welfare effects of the currency appreciation in an open economy -A simple discussion

Based on new open-economy macroeconomics, this paper provides simple discussions about the equilibrium conditions of labour market, goods markets and money market in a two-country world model economy. Given one-period wage sticky assumption, the following conclusions are obtained, the monetary policy can impact labour supply and thereby the equilibrium of labour market in the short run; The spill over effect of monetary policy in home and foreign countries implies an important international transmission channel in terms of equilibrium relationships between home and foreign countries, which also demonstrates the welfare effects of currency appreciation.     

20世纪90年代美国货币政策及对我国目前的启示

1993～2000年的美国和目前的中国都出现了高增长、低通胀的局面,一般认为美联储的货币政策为之作出很大贡献。本文在借鉴的基础上就我国目前在高增长、低通胀下的货币政策的几个主要问题提出建议。     

Devaluation and monetary policy with import compression

The consequences of exchange rate and monetary policies are investigated under two foreign exchange regimes. The analysis is motivated by the experiences in sub-Saharan Africa. The supply side of the open economy model developed by Buffle (1986) is modified to take into account the import dependency of the region. In the first regime, with endogenous foreign savings, overvalued exchange rate and expansionary monetary policy tend to increase the current account deficit. In the second regime, when intermediate imports are rationed to handle the foreign exchange shortage, overvaluation and monetary expansion are shown to be likely sources of output contraction. The cost of policy reorientation is reduced investment.     

Invoicing currency and the optimal basket peg for East Asia: Analysis using a new open economy macroeconomic model

An important characteristic of trade in Asia is that the US dollar is the dominant invoicing currency. This fact might have a consequence on the region's choice of the currency regime. To investigate this possibility, I develop a three country “new open economy macroeconomics” model that consists of East Asia, Japan, and the US. Assuming that East Asia pegs its currency to a basket of the other two's currencies, the optimal basket weights are derived numerically. It is shown that the weights under a realistic invoicing pattern are drastically different from those in the textbook case of “producer currency pricing.” J. Japanese Int.

Macroeconomic stabilization through monetary and fiscal policy coordination: Implications for European Monetary Union

In a two-country model, we consider the implications of monetary and fiscal policy coordination for macroeconomic stabilization. We show that the optimal regime is one of monetary and fiscal policy coordination under flexible exchange rates. In the context of the European Community, this suggests that the desire to fix exchange rates may not be costless. In addition, we show that fiscal coordination requires a relatively high degree of flexibility in fiscal policy. This result suggests that limits on the flexibility of fiscal policies, as suggested in the Delors Report, may hinder macroeconomic stabilization.     

The ‘trilemma’ hypothesis and policy implications for Fiji

This paper examines the trilemma constraint for Fiji; that is, we investigate how trilemma policy variables were used to address policy trade‐offs among the three objectives of exchange rate stability, monetary autonomy, and financial openness. Fiji makes an interesting case because of its policy orientation towards a stable exchange rate and adequate foreign reserves. Our results suggest that the trilemma constraint is binding for Fiji and policy priority is given to exchange rate stability and monetary policy independence, while less emphasis is placed on financial market openness. We also find that the actual policy levels do not deviate substantially from optimal levels, which evidences that Fiji's policy management has been efficient under the trilemma constraint. Finally, we also study the effects of various trilemma policy combinations and foreign reserve holdings on output growth and inflation.     

The evolving renminbi regime and implications for Asian currency stability

The Chinese authorities described the management of the renminbi after its 2005 unpegging from the US dollar as involving a basket of trading partner currencies. Outside analysts have detected few signs of such management. We find that, in the 2 years from mid-2006 to mid-2008, the renminbi strengthened gradually against trading partners’ currencies within a narrow band. In mid-2008, the financial crisis interrupted this experiment and the bilateral renminbi/dollar exchange rate stabilised at 6.8. The 2006-2008 experience suggests that a shared policy of gradual nominal effective appreciation renders East Asian currencies quite stable against one another. Such a shared policy would create favourable conditions for regional monetary cooperation.     

Autonomy and Effectiveness of Chinese Monetary Policy under the De Facto Fixed Exchange Rate System

This paper uses monthly data to examine the autonomy and effectiveness of monetary policy in China under the de facto fixed exchange rate arrangement in place from 1998 to 2005. The results obtained from Granger causality tests in a vector autoregression framework indicate that： （i） China actually conducted independent monetary policy during the fixed exchange rate period; and （ii） market-oriented policy measures are impotent in influencing real output and prices. The framework of the investigation into the autonomy of monetary policy adapts to the Chinese economic condition that primary loan and deposit rates are set by the central bank. Based on the empirical results, the present paper provides alternative strategies to improve the effectiveness of monetary policy in China, including developing the financial system and solidifying microeconomic fundamentals instead of forcing the adaptation of a more flexible exchange rate regime.
