市场分割下中国加工贸易出口主体分化问题研究

外部采购与加工贸易是近年来出现的新贸易现象,对中国来说,低廉的劳动力成本是取得加工贸易比较优势的主要原因,加工贸易发展进程中出口主体的分化是中国从城乡二元劳动力市场向城市二元劳动力市场转变的结果,要继续保持加工贸易比较优势,就应该增强劳动力市场的流动性,实现劳动力市场的统一。

The determinants of foreign direct investment into European transition economies

Using a panel dataset of bilateral flows of foreign direct investment (FDI), we study the determinants of FDI from Western countries, mainly in the European Union (EU), to Central and Eastern European ones. We find the most important influences to be unit labor costs, gravity factors, market size, and proximity. Interestingly, host country risk proves not to be a significant determinant. Our empirical work also indicates that announcements about EU Accession proposals have an impact on FDI for the future member countries. Journal of Comparative Economics 32 (4) (2004) 775–787.     

Capital needs in Eastern countries

This paper reviews estimated capital needs for Eastern Europe and rejects most of the claimed foreign capital contributions as too high and, in fact, unnecessary. It argues that whilst foreign investments may usefully assist reforms, they can neither substitute for reforms nor assure the success of reforms. Historically there is no evidence of sustained growth predominantly financed by foreign capital anywhere. The West's effort should therefore focus on assisting reform efforts, providing some capital but, above all, opening its markets to Eastern products.Opinions expressed in this paper are strictly personal. I would like to thank H. Handler for his comments.

Asymmetric FDI and tax-treaty bargaining: theory and evidence

Tax treaties are often viewed as a mechanism for eliminating tax competition, however, this approach ignores the need for bargaining over the treaty's terms. This paper focuses on how bargaining can affect the withholding taxes set under the treaty. In a simple framework, we develop hypotheses about patterns in treaty tax rates. A key determinant for these patterns is the relative size of bilateral foreign direct investment (FDI) activity. In plausible situations, more asymmetric countries will negotiate treaties with higher tax rates. This theory is then tested using 1992 data from US and Organization for Economic Cooperation and Development (OECD) bilateral tax treaties. Overall, the data supports the prediction that greater asymmetric FDI activity increases the negotiated tax rates.     

Existence of a competitive equilibrium in a one sector growth model with heterogeneous agents and irreversible investment

Summary. We prove existence of a competitive equilibrium in a version of a Ramsey (one sector) model in which agents are heterogeneous and gross investment is constrained to be non negative. We do so by converting the infinite-dimensional fixed point problem stated in terms of prices and commodities into a finite-dimensional Negishi problem involving individual weights in a social value function. This method allows us to obtain detailed results concerning the properties of competitive equilibria. Because of the simplicity of the techniques utilized our approach is amenable to be adapted by practitioners in analogous problems often studied in macroeconomics.

东道国ESP系统与东道国外商直接投资特征研究--以中国为例

国际直接投资地域结构的时空差异性对忽视东道国因素的传统国际投资理论提出了挑战。文章研究了东道国因素对国际生产资本地域运动的影响，提出了国际直接投资是东道国因素与投资主体三优势综合作用的结果，东道国环境、体制、政策系统的状态特征决定了东道国外资特征等观点，并实证研究了中国改革开放进程与外商对华投资规模和结构的内在互动性。     

Why Skew Selection, a Model of Parental Exploitation, Should Replace Kin Selection

Synopsis In his 1964 paper, William Hamilton wrote that inclusive fitness trumps direct fitness if, and only if, the effect of interactions among siblings on their parent’s fitness is ‘zero’. Kin selection models have succeeded only because they have ignored the fact that, if an altruist dies saving two siblings, the ‘zero impact on their parent’s fitness’ constraint is violated. Imagine a parent with three offspring. If two offspring drown, parental fitness is 1. On the other hand, if one altruistic offspring dies saving its two drowning siblings, parental fitness doubles to 2. Thus, direct fitness trumps inclusive fitness as an explanation for the evolution of altruism. In other words, parents that produce some portion of altruistic offspring willing to die to save some of their siblings (who would die without the intervention of the altruist) will realize greater fitness than parents producing no altruists. Skew selection, a bioeconomic extension of Michael Ghiselin’s (1974) parental exploitation model, is presented to explain the evolution of altruism from a direct fitness point of view.
