Congestion effects in a public-good economy

This paper considers a public-good economy with congestion, where participants jointly produce a public good from input of a private good. This economic model gives rise to a transferable-utility game, the profit game, that depends on consumer preferences and a congestion parameter. The simplicity of the game allows the maximum level of congestion that guarantees the nonemptiness of the core of the economy to be determined. It is known that the sustainability of the Lindahl equilibrium in the core of the economy depends on the distribution of profits. In this paper two distributions of profits are compared: the Lindahl solution and the marginal-contribution solution. The latter is more often in the core than the Lindahl solution which in turn Lorenz-dominates the marginal-contribution solution.     

"突破菏泽"经济发展模式的几点思考

菏泽市，古称曹州。历史上，菏泽因水而穷。建国前，黄河三年两决口，菏泽人民饱受自然灾害之苦，生产条件恶劣，工业几乎空白。建国后到改革开放前，菏泽处于吃粮靠统销、生产靠贷款、生活靠救济的“三靠”状态。长期恶劣的生存环境使不少菏泽百姓逐渐形成了不敢积累、不愿意积累、无意识积累的生活习惯。从1992年到2002年的10年间，菏泽市GDP年均增长6．8％，比全省平均水平低6个百分点，菏泽市累计实际利用外资仅占全省累计实际利用外资的1％，累计出口总值仅占全省累计出口总值的0．5％。2003年菏泽市人均GDP3337元，仅为全省平均水平的25％。1992年菏泽GDP同德州、聊城、滨州经济实力大体相当，现在差距却越来越大，从这些数字中折射出一个严峻的现实：菏泽何去何从？

个人教育投资的均衡分析

人力资本投资的关键形式是教育投资。文章认为,个人教育投资的均衡条件是边际成本等于边际收益。因为个人教育投资的边际成本递增,边际收益递减,所以必须采取多种措施刺激个人教育投资的积极性,才能促进我国教育事业的大发展。     

Valuing Mortgage Insurance Contracts in Emerging Market Economies

We develop a new option-based method for the valuation of mortgage insurance contracts in closed form in an economy where agents are risk neutral. While the proposed valuation method is general and can be used in any market, it may be particularly useful in emerging market economies where other existing methods may be either inappropriate or are too difficult to implement because of the lack of relevant data. As an application, we price a typical Serbian government-backed mortgage insurance contract.     

企业组织变革中的冲突管理研究

Sources of gains from international portfolio diversification

This paper looks at the determinants of country and industry specific factors in international portfolio returns using a sample of forty eight countries and thirty nine industries over the last three decades. Country factors have remained relatively stable over the sample period while industry factors have significantly increased during the last decade and dropped again since 2000. The importance of industry and country factors is correlated with measures of economic and financial international integration and development. We find that financial market globalization is the main driving force behind the changes in relative magnitude of the different shocks. Country factors are smaller for countries integrated in world financial markets and have declined as the degree of financial integration and the number of countries pursuing financial liberalization has increased. Higher international financial integration within an industry increases the importance of industry factors in explaining returns. Economic integration of production also helps in explaining returns. Countries with a more specialized production activity have higher country shocks.
