The division of labour and market structure

Most firms produce most of the time under conditions of substantial economies of scale. The division of labour, according to Adam Smith the mainspring of wealth, is intrinsically an economies of scale phenomenon. Market structure in most industries in characterized by a small number of suppliers and a larger number of customers. I explain this law of small numbers as the equilibrium of two forces: the deconcentration effect of imitation and the market spliting effect of further refinements in the division of labour by innovation. A deconcentrated market creates larger incentives for market splitting (product differentiation) by innovation than a concentrated market. But market splitting raises concentration in the market and it raises the number of different markets in the economy. Before the economies of scale of old products are fully exploited, new products are being offered which again are produced under conditions of economies of scale.     

Innovative productivity and returns to scale in the pharmaceutical industry

This study shows that firms in the pharmaceutical industry experience decreasing returns to scale in R & D as the level of R & D expenditures rises. The paper presents the results of our study of the innovative output of 16 pharmaceutical firms over a 19 year period. Given the strong correlation between R & D budgets and firm size, our study suggests the wave of mergers in the industry may yield less innovative productivity than managers expect.

Stability and Segregation in Group Formation

This paper presents a model of group formation based on the assumption that individuals prefer to associate with people similar to them. It is shown that, in general, if the number of groups that can be formed is bounded, then a stable partition of the society into groups may not exist. (A partition is defined as stable if none of the individuals would prefer be in a different group than the one he is in.) However, if individuals' characteristics are one-dimensional, then a stable partition always exists. We give sufficient conditions for stable partitions to be segregating (in the sense that, for example, low-characteristic individuals are in one group and high-characteristic ones are in another) and Pareto efficient. In addition, we propose a dynamic model of individual myopic behavior describing the evolution of group formation to an eventual stable, segregating, and Pareto efficient partition.

政府公职人员经济人性边界界定与启示

政府公职人员是特殊经济人,并且从"经济人"角度、从历史性角度、从社会契约论角度、从初始社会分工及分工发展过程角度看,政府公职人员经济人性应有必要的边界。其经济人性发挥应符合作用空间的"非市场性"、经济人性范围的日趋"紧缩性"、经济人性目标满足渠道的"单一性"及较强的"社会性"这些内在规律。把握这些规律,可有效地建立针对政府公职人员的约束机制和非市场性的竞争机制,还可有效地促进民主发展,这对提升基本公共服务综合绩效及构建和谐社会都具有重要意义。     

《笨花》与《棉花垛》乡土叙述的比较——兼及对《铁凝的<笨花>批判》的批判

《笨花》因为和作者早年的《棉花垛》有相似之处而受人非议。《笨花》以乡土叙述的方式描绘了河北农村的风土人情,但是《笨花》中还混杂了多种西方话语,即宗教、女性话语和民族解放话语,这些与乡土社会本应是相抵牾的。然而作者为了塑造乡土社会的和谐风貌,通过对各种话语的挪移,而使它们与乡土叙述的冲突彻底消解,造成了文本张力的缺失。     

政府在发展高等职业教育中的角色定位思考

高等职业教育是我国高等教育的有机组成部分,政府在发展高等职业教育培训中拥有无可争议的地位,但政府能否对自己的角色加以理性定位却事关高职教育的健康发展。依据中国的具体国情,本文提出政府在高职教育发展中应该扮演催化剂、支持者、激励者和调控者的理性角色。     

Government Deficit, Public Investment, and Public Capital in the Transition to an Aging Japan

This paper examines the effects of government deficits, public investment, and public capital on welfare in the transition to an aging Japan by applying a simulated general equilibrium growth model. One of the main results of this paper is that targeting only high economic growth would mislead us as to economic policies, and that a policy to reduce future government deficits is most preferable for almost all generations, even though a cut in future deficits must be followed by a decrease in public investment, thus a decrease in public capital in the future.
