Economic and ethnic factors in Kenyan migration movements

The impact of economic and ethnic factors on migration in Kenya is examined using data from the 1979 census and the Kenya Fertility Survey of 1977-1978 and ordinary least squares multiple regression analysis. The results indicate that fertility and child mortality are positively related to migration. Most migrations are of short distance, and ethnic linkage effects vary by tribal group. Other factors considered include income, land supply, and education.     

实验经济学:兴起、应用与意义

2002年度诺贝尔经济学奖授予了美国经济学家弗农·史密斯，以表彰他在实验经济学领域所作出的杰出贡献。实验经济学对于中国经济工作者仍是一个比较陌生的领域。本文将对实验经济学的发展过程、基本方法及主要特点作简单介绍。一、实验经济学的兴起和发展实验经济学的研究，是在可控制的实验环境下对某一经济现象，通过控制实验条件、观察实验者行为和分析实验结果，以检验、比较和完善经济理论或提供决策依据的一门学科。人们在很长一段时间里始终固守着经济理论难以实验的思维定式。弗农·史密斯教授敏锐觉察到实验经济理论的作用，并首次…     

A forecasting model of the Kenyan economy

A demand-oriented macroeconometric model of the Kenyan economy is developed and estimated in line with the cointegration technique. The estimated structure of the model is used to perform policy simulation experiments to determine the sensitivity of key macroeconomic variables to changes in exchange rate, net government current expenditure and nominal interest rate. The results of policy simulation experiments reveal that the exchange rate and fiscal policies are relatively more effective than the monetary policy, i.e. changing the nominal interest rate, in influencing the level of economic activity. The results point to the possibility of devaluation improving the international trade balance.     

政府公益性项目管理模式--实施建设管理代理制引起的思考

如何管理好政府工程项目是世界各国一直在探索的问题,对于发展中国家来说更是如此。我国当前政府公益性投资项目正处于高速发展时期,加之体制的改革,政府公益性投资项目效益低下更为明显。目前许多地区,特别是西部地区,一方面继续进行着体制的转轨,另一方面面临着大规模的政府公益性投资项目,寻求合理的项目管理模式具有重要的现实意义。本文针对目前一些地方政府提出的政府公益性投资项目实行建设管理代理制为研讨对象,在对国外政府公益性项目管理模式进行分析的基础上,通过与我国一些地区目前做法的比较,提出地方政府可借鉴的一…     

Contests with spying: A comment

The subject of the following comment is a paper by Baik and Shogren which has been published in this journal (Vol. 11, No. 3 (1995) pp. 441–451). In their game-theoretic model, Baik and Shogren connect the informational states of the agents in a way which leads to inconsistencies.     

Quasi-hyperbolic preferences and retirement: A comment

Diamond and Koszegi [Diamond, P. and Koszegi, B. (2003), “Quasi-Hyperbolic Preferences and Retirement,” Journal of Public Economics, 87: 1839–1972] have argued that quasi-hyperbolic discounting can cause dynamic inconsistency in planning when to retire as well as in consumption plans. This comment shows that in a simple model with such preferences, retirement plans are never time-inconsistent, as these same preferences keep savings too low for individuals to ever be able to afford unplanned early retirement. Although only a simple example is presented here to demonstrate the point, this insight suggests the application of ordiamond03's framework should be reconsidered. The model presented needs to be extended to find robust general conclusions.

Government size and macroeconomic stability: A comment

We show that in a standard, technology shock-driven one-sector real business cycle model, the stabilization effects of government fiscal policy depend crucially on how labor hours enter the household's period utility function and the associated labor-market behavior. In particular, as Galí [European Economic Review 38 (1994), 117-132] has shown, when the household utility is logarithmic in both consumption and leisure, income taxes are destabilizing and government purchases are stabilizing. However, the results are reversed when preferences are instead convex in hours worked. That is, income taxes are now stabilizing and public spending is destabilizing. Furthermore, under both preference specifications, the magnitude of cyclical fluctuations in output remains unchanged when the income tax rate and the share of government purchases in GDP are equal (including laissez-faire).
