The approach to transforming the traditional agricultural economy: a research on the multiple paths of poverty alleviation and transformation in rural China

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”. __________ Translated from The Journal of World Economy (世界经济), 2005,(2) (in Chinese)     

Improved estimation of portfolio value‐at‐risk under copula models with mixed marginals

Portfolio value‐at‐risk (PVAR) is widely used in practice, but recent criticisms have focused on risks arising from biased PVAR estimates due to model specification errors and other problems. The PVAR estimation method proposed in this article combines generalized Pareto distribution tails with the empirical density function to model the marginal distributions for each asset in the portfolio, and a copula model is used to form a joint distribution from the fitted marginals. The copula–mixed distribution (CMX) approach converges in probability to the true marginal return distribution but is based on weaker assumptions that may be appropriate for the returns data found in practice. CMX is used to estimate the joint distribution of log returns for the Taiwan Stock Exchange (TSE) index and the associated futures contracts on SGX and TAIFEX. The PVAR estimates for various hedge portfolios are computed from the fitted CMX model, and backtesting diagnostics indicate that CMX outperforms the alternative PVAR estimators. © 2006 Wiley Periodicals, Inc.

A comparison of Ad valorem and per unit taxes in regulated monopolies

This paper compares the output and revenue effects in the rate-of-return regulated monopoly model. Both the ad valorem and the unit tax generally decrease the use of capital, and as such, reduce the output and raise the price. In addition, it is shown that Suits and Musgrave's conclusion of higher revenue of an ad valorem tax at a given output can apply to a regulated monopolist if the marginal product of labor under the ad valorem tax is greater than or equal to that under the unit tax. Similarly, their second conclusion, that for a given tax revenue an ad valorem tax has a larger output than a unit tax rate before the revenue-maximizing tax rate, can also apply to the regulated monopolist.

国有企业融资次序的政治经济学分析

与经典资本结构理论的结论不同，我国国有企业的融资次序恰好是倒序的。这一现象有着深刻的政治经济学内涵，本质上它是由国家追求义理性的最大化，缓解财政压力的行为所内生决定的。因此，单纯从西方主流理论出发，不考虑我国转轨经济的背景对国有企业融资行为和由此而引致的治理结构所进行的分析，是不得要领的。
