汇率、利率、税率：名义和实际

当前我国经济运行情况以及面临的问题 过去的一年里，我国经济保持了稳定增长的态势，在全球经济特别是关、日和欧三大经济体同时陷入衰退的情况下，2001年我国国内生产总值达到95800多亿元，同比增长率为7．3％。更令人感到鼓舞的是，中国在2001年加入WTO，正式成为世界贸易组织的一员，中国的对外开放进入了一个新的阶段。 但在成功数字的外表下，我们还应该看到中国经济的一些问题以及在2002年可能遇到或者已经遇到的一些难题。2001年中国经济增长前高后低，四个季度的经济增长一路滑坡，前3个季度的增长速度分别是8．1％、7．8％和7％，第4季度GDP增长也很难达到7％，11月份居民消费价格总水平比去年同月下降3％，又面临通货紧缩的威胁。2001年的经济增长，主要是由国内投资和消费需求的增长拉动的。由于国际经济严重衰退，一方面，我国出口增速下降，大约在6％左右，净出口减少，对经济增长的贡献度为负值；另一方面，促使外资流入加快，实际利用外资增长近20％，减弱了出口下降的影响。……     

A Cross-Country Comparison of Okun's Coefficient

In this paper Okun's law is tested for the G7 countries in order to compare the responsiveness of unemployment to economic growth. Cyclical unemployment and output are extracted using Harvey's structural time series model. Okun's coefficient is estimated by OLS, rolling OLS, and SUR. The coefficient seems to be highest for North America and lowest for Japan, a result that can be explained in terms of differences in labor market rigidities. The rising absolute value of the coefficients over time indicated by the results of rolling OLS is explained in terms of labor market reform.J. Comp. Econom.,June 1997,24(3), pp. 335–356.

Exchange Rates and Outward Foreign Direct Investment: US FDI in Emerging Economies

This paper investigates the effect of exchange rates on US foreign direct investment (FDI) flows to a sample of 16 emerging market countries using annual panel data for the period 1990–2002. Three separate exchange rate effects are considered: the value of the local currency (a cheaper currency attracts FDI); expected changes in the exchange rate (expected devaluation implies FDI is postponed); and exchange rate volatility (discourages FDI). The results reveal a negative relationship between FDI and more expensive local currency, the expectation of local currency depreciation, and volatile exchange rates. Stable exchange rate management can be important in attracting FDI.     

Democratization and Real Exchange Rates,

In this article, we combine two so far separate strands of the economic literature and argue that democratization leads to a real exchange rate appreciation. We test this hypothesis empirically for a sample of countries observed from 1980 to 2007 by combining a difference‐in‐difference approach with propensity score matching estimators. Our empirical results reveal a strong and significant finding: democratization causes real exchange rates to appreciate. Consequently, the ongoing process of democratization observed in many parts of the world is likely to reduce exchange rate distortions.     

Money Market Uncertainty and Retail Interest Rate Fluctuations: A Cross-Country Comparison

Abstract. This paper analyzes empirically the relationship between money market uncertainty and unexpected deviations in retail interest rates in a sample of ten OECD countries. We find that, with the exception of the United States, money market uncertainty has only a modest impact on the conditional volatility of retail interest rates. Even for the United States, we find that the effects of money market uncertainty are spread out over time. Our results also indicate that money market uncertainty tends to be passed on to retail rates to a lesser extent in countries where banking relationships play a substantial role.     

Time-Varying Risk, Interest Rates, and Exchange Rates in General Equilibrium

Under mild assumptions, the data indicate that fluctuations in nominal interest rate differentials across currencies are primarily fluctuations in time-varying risk. This finding is an immediate implication of the fact that exchange rates are roughly random walks. If most fluctuations in interest differentials are thought to be driven by monetary policy, then the data call for a theory which explains how changes in monetary policy change risk. Here, we propose such a theory based on a general equilibrium monetary model with an endogenous source of risk variation—a variable degree of asset market segmentation.     

Exchange Rates, Nominal Inertia and Inflation

This paper examines the use of the nominal exchange rate in achieving disinflation under managed exchange rate regimes. Most previous empirical studies have not explicitly identified expectations in the wage and price setting behaviour of their econometric models, despite the importance of expectations both during a disinflation and in correcting misalignments. This has meant that costs due to nominal inertia and non-neutralities have not been addressed separately from questions of credibility. We present results for the UK economy using both a theoretical and empirical model in which firms and workers form rational expectations, but where there is also nominal inertia. We identify costs in using the exchange rate to change the inflation rate, and also the costs involved in correcting any disequilibria in the real exchange rate.     

Interest Rates, Irreversibility, and Backward-Bending Investment

This paper studies the effect of interest rates on investment in an environment where firms make irreversible investments with uncertain pay-offs. In this setting, changes in the interest rate affect both the cost of capital and the cost of delaying investment to acquire information. These two forces combine to generate an aggregate investment demand curve that is a backward-bending function of the interest rate. At low rates, increasing the interest rate raises investment by increasing the cost of delay.     

A Theory of Exchange Rates and the Term Structure of Interest Rates

This paper defines the concepts of indirect and direct risk premium effects and analyzes their properties in an exchange rate model. In the model, these effects are endogenously determined in a rational expectations equilibrium. For the effect of an interest rate shock, they have the opposite signs and the indirect risk premium effect can dominate the direct risk premium effect under reasonable parameters. This means that domestic short‐term bonds and foreign bonds are complements in the model even though domestic long‐term bonds and foreign bonds are substitutes. This model, focusing on the indirect risk premium effect and on the term structure of interest rates, can be combined with a small sample bias approach to explain stylized facts about the forward premium anomaly, which is found for short‐term interest rates, but not for long‐term interest rates.     

Productivity Trends in Europe: Implications for Real Exchange Rates, Real Interest Rates, and Inflation

The paper examines a long–run (neoclassical) framework in which differences in productivity growth across sectors and countries lead to inflation differentials. In a currency union, these inflation differentials imply cross–country differentials in real interest rates. The authors estimate the likely size of these differentials for European Union countries, discuss the potential costs of persistent inflation differentials, and comment on the conflicts they may cause within Economic and Monetary Union (EMU). The analytical framework is a variant of the Balassa–Samuelson "productivity hypotheisis," which relates sectoral productivity trends to trends in the relative price of home goods.     

A Case for Managed Exchange Rates*

The incorporation of adaptive expectations by Dornbusch in a Mundell-Fleming model modifies significantly the traditional results of policy effectiveness in a small, open economy. While monetary policy is still able to influence aggregate demand when flexible exchange rates prevail, the effects of this policy on other important variables in the economy during the adjustment process to a new equilibrium may be considered sufficiently ‘disruptive’ so that the authorities will be hesitant to use their only fully-effective policy instrument for income-stabilization purposes. However, by adding a target level for the exchange rate to their list of goal variables and by using an appropriate mix of monetary and fiscal policies, it appears to be possible for the government to avoid these disruptive side effects.     

Forward Rates,Interest Rates,and Expectations Under Alternative Exchange Rate Regimes*

A model comprising spot and forward foreign exchange markets and a domestic credit market is used to examine the trade-off between volatility in the nominal exchange rate and domestic interest rate. It also shows how a slowly crawling spot rate can raise interest rate volatility and the amplitude of reserve flows. Finally, the paper extends a finding by Driskill and McCafferty that the exchange rate effects of external shocks are differently affected by the responsiveness of speculation to expected profits; high responsiveness makes the spot exchange rate more sensitive to foreign financial shocks but less sensitive to trade balance shocks.     

School Attainment, Completion, and Economic Development: A Cross-Country Analysis

The primary aim of this paper is to examine the relationship between school attainment, school completion, and economic development. In doing so it also examines the effect of other macroeconomic variables on school attainment and completion. Estimation is conducted using a panel dataset of 138 countries. Our results show that income levels, government expenditure on education, and political instability all have significant effects on school completion and attainment. In addition these variables have different effects on male and female schooling. Our results have important policy implications and in particular allow policymakers to identify different instruments to target the problem of non‐completion of schooling.

Bilateral Exchange Rates and Jobs

We study the labor market effects of realignment in fixed bilateral exchange rates, such as China's peg to the US dollar. We employ the open economy model by de Melo and Robinson to identify the core parameters of the real, trade side of the economy driving the unemployment effects of bilateral exchange rate realignment. A small open economy version of the model is explored analytically and a large multicountry version numerically. Analytics in the small open economy model show that unemployment effects of adjusting of a bilateral peg hinge on the fraction exported to and imported from the trading partner. A larger fraction exported to and a smaller fraction imported from the trading partner make it more likely that revaluation of a trading partner's currency has beneficial effects. Numerics in the large economy model show that Chinese revaluation can generate both positive and negative unemployment effects depending upon underlying parameter values. Adverse unemployment effects can go along with an improving trade balance.     

Fiscal Policy and Exchange Rates

This paper examines the dynamics of the nominal exchange rate and fiscal deficits in a continuous time optimizing general equilibrium model with OLG. It is shown that alternative financing modes of budget deficits imply different patterns of adjustment along the transitional path towards the steady-state equilibrium. In particular, the respect of public solvency without money financing is not sufficient to avoid the depreciation of the exchange rate in the long-run after a fiscal expansion. In addition, money and tax financing generate opposite intergenerational reallocation of wealth.
