Principles for a European Union''s Public Debt

The EU has neither the power to tax nor the right to run a public debt. We analyze if the EU should receive the right for public indebtedness. We make use of the normative theory of public indebtedness and of positive political economy analysis. Our normative analysis identified specific cases for an appropriate use of public indebtedness. According to the political economy analysis, a misuse of public debt may be possible. As the implementation of strict constitutional constraints can limit this misuse, we propose the assignment of a right to public borrowing to the EU within tight constitutional restrictions.     

Spousal Complementarity in Home Production

A bstract .   Economists have increasingly recognized the growing role of married women in the labor market by treating the labor supply decisions of married couples as joint decisions. However, they have yet to apply the same reasoning to home production. We build a more complete model of household time allocation that consists of a system of simultaneous equations estimating hours of labor supply and home production. Using data on white couples from Wave XXV of the Panel Study of Income Dynamics, we find that working wives act as if their husbands are substitutes for home production while other wives do not. Husbands' responses to their wives' behavior depends upon whether children are present.     

金融状况指数的理论设计及应用研究

考虑到当前金融状况指数（FCI）理论构建和指标选取存在的片面性,本文以产品市场均衡和货币市场均衡为切入点,提出将非人力财富比重作为重要因素纳入FCI的新观点。并针对每一个要素,均用验证性因素分析等方法从若干指标中筛选出代表性最佳的指标,再以VAR模型为赋权方法得到我国的FCI。通过与CPI的因果关联、动态分析以及与部分学者的研究成果进行比较,发现经过指标定量筛选后构建的FCI具有最佳经济效果,更符合中国现实。     

分整阶数半参数估计的有限样本性质研究

随着对经济和金融时间序列长记忆性的研究,分整阶数估计已成为当前理论研究的焦点问题。以对数周期图回归和局部Whittle方法为代表的半参数分整阶数估计方法在实践中得到广泛应用,但对这两类半参数估计方法的有限样本性质的比较则鲜有涉及,影响了在实践中对估计方法的选择。利用蒙特卡洛模拟方法,在不同数据产生的过程下,这两种半参数估计方法有限样本性质的研究结果表明：在ARFIMA(0, d, 0)过程下,LW类估计量具有较好的小样本性质;在平稳ARFIMA(1, d, 0)过程下,本文建议的QGPH估计量的有限样本性质要优于其他对数周期图估计量;在非平稳过程下,MGPH的偏差最小。

TESTING POVERTY LINES

In theory, a poverty line can be defined as the cost of a common (inter‐personally comparable) utility level across a population. But how can one know if this holds in practice? For groups sharing common consumption needs but facing different prices, the theory of revealed preference can be used to derive testable implications of utility consistency knowing only the “poverty bundles” and their prices. Heterogeneity in needs calls for extra information. We argue that subjective welfare data offer a credible means of testing utility consistency across different needs groups. A case study of Russia's official poverty lines shows how revealed preference tests can be used in conjunction with qualitative information on needs heterogeneity. The results lead us to question the utility consistency of Russia's official poverty lines.     

FACTOR ACCUMULATION AND THE TERMS OF TRADE: APPLICATIONS TO THE ASIAN FINANCIAL CRISIS

Abstract.  This paper investigates the effects of population growth and capital accumulation on trade and welfare. In the absence of a terms of trade effect, an population increase reduces the standard of living and causes a reduction in welfare. An increase in population causes deterioration in the terms of trade of a labour abundant country, whereas capital accumulation improves them, regardless of the source of growth. Moreover, an increase in the South's population is immiserizing.
