In investigating the causal relation between government revenue and spending, our empirical results support the tax-and-spend
hypothesis for Egypt and the fiscal synchronization hypothesis for Jordan. Breaking away from these historical trends is essential
for both countries to eliminate the budget deficit and therefore ensure the availability of domestic saving for private investment.
To cope with unemployment and poverty, continuing privatization is recommended for both countries to improve productivity
and efficiency in the domestic economy. Privatization should lead to higher domestic saving and investment and at the same
time eliminate the budget deficit by enhancing revenue and curbing spending. (JEL H62, H63) 相似文献

We consider a model of an oligopolistic market with heterogeneous firms and products where neither the cost nor the demand functions are common knowledge. Instead, each firm only has some vague ideas about the price strategies adopted by its competitors which is modelled by a fuzzy set. In analogy to the notion of an "equilibrium of actions and beliefs" we define and characterize a generalized Nash-equilibrium and show its existence under general conditions. Furthermore, the impact of the fuzzy information on the equilibrium outcome is analyzed by means of a comparative static analysis within a particular model framework.Received: 28 May 2002, Accepted: 25 December 2002, JEL Classification:

A bstract . Despite interest in the influence of religion on economic activity by early economists like Adam Smith, modern economists have done little research on the subject. In light of the apparent religious fervor in many parts of the global economy, economists' seeming lack of interest in studying how religious cultures enhance or retard the globalization of economic activity is especially surprising. This article makes a contribution toward filling this void by examining how religion affects international trade. Specifically, we examine whether the sharing of religious cultures enables the formation of exchange networks that can overcome the failure or nonexistence of other social and economic institutions necessary for completing complex international transactions. We apply an expanded gravity model of international trade to control for a variety of factors that determine trade, and we use two recently developed regression methods, scaled OLS and nonlinear least squares, to exploit the model to its fullest. We find that the sharing of Buddhist, Confucian, Hindu, Eastern Orthodox Catholic, and Protestant cultures by people in different countries has a significantly positive influence on bilateral trade, all other things equal. The sharing of Roman Catholic culture has a significantly negative influence on bilateral trade, and the sharing of Islamic and Judaic cultures neither promotes nor discourages international exchange. These results suggest that some religious cultures are more conducive than others for forming international trade networks. 相似文献

In this paper, we consider the problem of estimating a selected set of contrasts between v treatments using a block design consisting of b blocks of size k. Traditionally, the construction of A-optimal block designs for such situations has been carried out assuming a fixed effects model. In this paper, we show that A-optimal designs constructed under a fixed effects model are robust in the sense that these designs have maximal minimal efficiency when considered among all available designs and under all possible mixed effects models.

Prior research has employed a number of methods to test for speculative bubbles in asset prices, including a method based
on the concept of duration dependence. This study explores whether duration dependence tests for speculative bubbles are sensitive
to specification decisions. Our results question the efficacy of using measures of duration dependence to test for speculative
bubbles. In particular, we find that evidence of duration dependence is sensitive to the method of correcting for discrete
observation of continuous duration, the use of value-weighted versus equally weighted portfolios, and the use of monthly versus
weekly runs of abnormal returns. (JEL C41, G12) 相似文献

中国政策性创业资本的地位及定位研究 总被引:1,自引:0,他引:1

文中将创业资本划分为政策性创业资本与商业性创业资本,提出政策性创业资本不应以追求商业利润或与私人部门分享利润为目标,而是以税收、就业、区域发展、出口和经济发展作为追求目标。它应该承担起更多的社会功能,政策性创业资本的定位就在于通过国家宏观政策方面的调节来分散、分担商业性创业资本的经营风险,吸引、引导、鼓励、扶持商业资本进入创业投资领域。 相似文献
