Five years after the introduction of unified monetary policy in the EMU, some member countries are wondering whether they have ceded too much of their policy-making powers. The fact that National Central Banks no longer carry out sizable expansionary open market or foreign exchange market operations suggests that they face substantially reduced abilities to set economic policy.This paper demonstrates that, in fact, very little power has been yielded: on the fiscal front, the force of such policy initiatives is enhanced by the fixity of the exchange rate. On the monetary front, we show that there is an observational equivalence between all Central Bank actions under fixed exchange rates. This implies that the authorities retain the same amount of policy flexibility as before. So long as they use an alternative form of policy initiative, carrying out what previously would have been characterized as sterilized foreign exchange market operations, their ability to influence the macro performance of their economy is undiminished. 相似文献

Reductions in international interest rates are a major cause of capital flows to emerging economies. Increases in domestic interest rates are a frequent policy response to the resulting price increases. This is often unsuccessful. The paper suggests a theoretical explanation based on distinctive features of emerging financial markets, including imperfect asset substitutability and imperfect capital mobility for some sectors of the economy. It concludes that the appropriate policy response to capital inflows may be lower interest rates. 相似文献

随着远期外汇合约近几年来在我国的逐步推行,外汇市场活跃的同时也增加了外汇交易的信用风险,。要实现外汇市场的有序开放和稳定发展,就必须对其实行有效的风险管理,这包括交易主体对信用风险的识别,处置和外部监管。 相似文献

Transforming a traditional agricultural economy into a modern economy is one of the main themes in economic development. Through
theoretical and empirical analysis, this paper finds out that the key to transformation is to raise the economic value of
people, to improve human capital investment and to match the stocks of physical and human capital. China’s rural economy is
on the edge of economic take-off, and different zones may pursue different paths for transformation. The source of rural poverty
is not the scarcity of income or consumption, but the deficiency of education, social security, medical care and economic
opportunity, which we define as “capability poverty”.

Statistical inference based on the Weibull distribution, a distribution widely used in reliability and survival analysis,
is usually difficult as it often involves numerical computation and approximation. However, this distribution can be transformed
to near-normality by a simple power transformation. Based on this transformation, a prediction interval (PI) for its median
can be easily constructed through an inverse transformation. The procedure for selecting the best power transformation through
minimizing Kullback-Leibler information is described. The property of this transformation-based PI is investigated. Simple
correction factors are also proposed. It is shown that the transformation-based PI with corrections performs well, irrespective
of the sample size and parameter values. Simulation results show that the new PI generally outperforms the existing PI. Numerical
examples are given for illustration. 相似文献

I. Introduction The rapid rise of the economic weight of China in the world economy has increasingly caught the attention of many analysts as well as policy-makers, eliciting various opinions on the global implications. Although China’s economic performance in the past 2 decades46 Pingfan Hong / 45 – 55, Vol. 14, No. 2, 2006 or so is indeed miraculous, the rest of the world should become less surprised or bewildered if they see China’s recent performance from a long-run historical perspe… 相似文献

We conduct tests for the contribution of speculative bubbles to farmland prices. These tests are carried out under the hypothesis that farmland investors rationally form expectations. The outcome of tests reported here allows us to infer whether farmland prices are determined by market fundamentals-discounted returns from the highest economic land use-or whether rumors about farmland price movements are self-fulfilling. The tests are stationarity and cointegration tests relating farmland prices to rents. The tests are carried out using data from three farm production regions-the Corn Belt, the Northern Plains, and the Lake States. In each region, we find little evidence to reject the hypothesis that market fundamentals determine farmland prices. 相似文献
