This study shows, both theoretically and empirically, that in a world where capital as well as exchange markets are imperfect it is incorrect to employ mid-market rates to estimate CIP relationships. Developing and using the correct specification, we estimated covered interest parity relationships between the overnight U.S. Euro-dollar and Canadian interbank markets, for the 1986-1992 period. It was found that covered interest parity holds for both directions. However, the speed and pattern of adjustments with which potential arbitrage profits are eliminated are not symmetric between U.S. Euro-dollar and Canadian interbank markets. [GI51 相似文献
Our analysis focuses on the effect of U.S. government pressure on Korea to adopt product patents for chemical and pharmaceutical products. American pressure began in November 1985 and ended with the Korean Legislature's passage of a new patent law in December 1986. We conduct an event study of the effect of the new patent law on the value of Korean pharmaceutical firms listed on the Korea Stock Exchange. Regression analysis shows that the new law induced excess returns of-74 percent over the 14-month analysis period. The results suggest that adoption of stronger patent laws reduced Korea's wealth.

An error correction model (ECM) is used to study the Properties of money demand and to evaluate the appropriate monetary policy in PNG. The study confirms that the determinats of money demand are real GDP, nominal interest and inflation rate. The income elasticity of money demand is very low. The demand for money in PNG was stable during 1979-95, suggesting that the monetary targeting regime by the PNG Central Bank is feasible. However, as PNG proceeds with economic reforms that Includes financial sector reform and a floating exchange rate regime, the stability of the demand for money may have to be re-examined periodically. The best approach for conducting the monetary policy in PNG is to target the inflation rate. [E41, E52, C22] 相似文献
This paper develops a (stylized Asia-America) Heckscher-Ohlin world economy in which the equilibrium rate of unemployment is endogenous. We examine the impact of various economic shocks on unemployment in the global economy. Harrod-neutral or Hicks-neutral technical progress across all industries in Asia leads to a terms of trade improvement for America but raises America's unemployment rate. Introducing a third country such as the block of former socialist economies results in higher unemployment for both Asia and America. Protection in America lowers American equilibrium unemployment but raises Asia's unemployment. [E24] 相似文献
During theh last few years policy evaluation has become an important area of research. Urban and regional policies have been subjected to more detailed scrutiny than ever before. Yet the gowing body of evaluative research remains isolated from many wider debates in the social and economic sciences. This can be attributed partly to the predilection for scientific methods, caused by the apparent certainty and objectivity they confer. This orientatioin is reflected in the tendency to separate evaluation from the policy process; the narrow perspective of many evaluative studies; the emphasis on quantification; the mechanical approach to analysis; and the inattention paid to undestanding causal processes. 相似文献
Recent research has reported the lack of correct size in stationarity test for PPP deviations within a linear framework. However, theoretically well motivated non-linear models, such as the ESTAR, appear to parsimoniously fit the PPP data and provide an explanation for the PPP ‘puzzle’. Employing Monte Carlo experiments the size and power of the non-linear tests are analysed against a variety of nonstationary hypotheses. Aslo the ESTAR model is fitted to data from high inflation economies. The results provide further support for ESTAR specification. 相似文献
Summary. Money provides liquidity services through a cash-in-advance constraint. The exchange of commodities and assets extends over an infinite horizon under uncertainty and a sequentially complete asset market. Monetary policy sets the path of rates of interest and accommodates the demand for balances through open market operations or loans. A public authority, which, most pertinently, inherits a strictly positive public debt, raises revenue from taxes and seignorage, and it distributes possible budget surpluses to individuals through transfers. Competitive equilibria exist, under mild solvency conditions. But, for a fixed path of rates of interest, there is a non-trivial multiplicity of equilibrium paths of prices of commodities. Determinacy requires that, subject to no-arbitrage and in addition to rates of interest, the prices of state-contingent revenues be somehow determined.Received: 16 April 2003, Revised: 16 January 2004, JEL Classification Numbers:

We propose an extension of the standard general equilibrium model with production and incomplete markets to situations in
which (i) private investors have limited information on the returns of specific assets, (ii) managers of firms have limited
information on the preferences of individual shareholders. The extension is obtained by the assumption that firms are not
traded directly but grouped into ‘sectorial’ funds. In our model the financial policy of the firm is not irrelevant. We establish
the existence of equilibria and discuss the nature of the inefficiencies introduced by the presence of asymmetric information.
We also illustrate the properties of the model in three simple examples.
We would like to thank Alberto Bisin, Armando Dominioni, Piero Gottardi, Tito Pietra, Paolo Siconolfi, and an anonymous referee

This article considers age and gender differences in the probability and consequences of job mobility in Russia. Little is known about who is mobile and whether mobility impacts wages once the characteristics of movers are controlled for. Results show a gender difference in the likelihood of exit but not promotion. Results also show that promotions have a positive effect only on the wages of young women, but young men's wages are not affected. Further, young men see a significant decrease in wages following an exit, while young women are not affected by firm exit. The article shows that early mobility is particularly important for women, who earn less overall. Results help to understand processes of inequality in wages and conditions that occur due to sorting, and the importance of promotions as ‘life chances’ which lead to ‘career-track jobs’. Gender differences in securing such life chances may help to understand gaps in earnings, which emerge later. 相似文献
We use topic modeling to study research articles in environmental and resource economics journals in the period 2000–2019. Topic modeling based on machine learning allows us to identify and track latent topics in the literature over time and across journals, and further to study the role of different journals in different topics and the changing emphasis on topics in different journals. The most prevalent topics in environmental and resource economics research in this period are growth and sustainable development and theory and methodology. Topics on climate change and energy economics have emerged with the strongest upward trends. When we look at our results across journals, we see that journals have different topical profiles and that many topics mainly appear in one or a few selected journals. Further investigation reveal latent semantic structures across research themes that only the insider would be aware.
