享年次高的诺贝尔奖得主——新制度经济学大师罗纳德·科斯

1991年诺贝尔经济学奖得主、英国和美国(双重国籍)经济学家和法学家罗纳德·科斯是交易成本理论、科斯定理和科斯猜想的首创者,法律经济学和新制度经济学的开山鼻祖,产权理论和产权经济学的奠基人,他开启了产权理论、法律经济学和新制度经济学三个领域的研究方向。科斯是国际经济学界的泰斗级大师和巨匠,他在阐述经济组织产生的原理、交易成本分析以及推动法学、经济史和组织理论的发展方面作出重要贡献,发展了新古典经济学,开创了现代企业理论。科斯一生都关切和热爱中国,一直密切关注着中国的经济改革,其经济理论和深邃思想对中国的经济改革影响巨大而深远。     

An alternative proof of the nonemptiness of the private core

Summary. We focus on the private core [19] of an economy with a finite number of agents with differential information, a continuum of states and an infinite number of commodities. We state a nonemptiness result for the private core and provide a proof based on a fixed-point argument. Received: October 4, 1999; revised version: June 7, 2000     

非法吸收公众存款罪与民间融资

近年来的司法实践,对非法吸收公众存款罪的认定有扩大化倾向。许多个案不考虑融资的目的是否为企业自身发展,不考虑是否造成损害后果、是否具有侵占、诈骗的故意等特征,抹煞非法吸收公众存款犯罪与合法的民间借贷的区别。这一扩大化的倾向与加入世贸后打破金融垄断、鼓励金融市场竞争、民间金融逐步合法化的趋势是背道而驰的,所以有必要对非法吸收公众存款罪与民间融资加以区分。     

一类泛函脉冲微分方程周期正解的存在性

The Generalized Composite Commodity Theorem and Food Demand Estimation

This article reports tests of aggregation over consumer food products and estimates of aggregate food demand elasticities. Evidence that food demand variables follow unit root processes leads us to build on and simplify existing tests of the Generalized Composite Commodity Theorem. We compute food demand elasticities using a method of cointegration that is shown to apply to a convenient but nonlinear functional form. Estimates are based on consumer reported expenditure data rather than commercial disappearance data.

Factor substitution and factor intensities in models with more factors than goods

This paper considers the commodity prices–factor prices relation in models with more factors than consumption goods. Under some simple factor substitutability assumptions, many results in the   n  ×  n   cases have counterparts in the   l  ×  n   cases. The proportional price changes of the "middle factors" will be trapped between those of the "extreme factors". A weak and a strong Stolper–Samuelson theorem can also be proven. If the numbers of goods and perfectly complementary factors are equal and the production functions have the nested constant elasticity of substitution form, two of the complementary factors would have the most extreme relative price changes, regardless of the factor intensities.
