Modeling Conditional Yield Densities

Given the increasing interest in agricultural risk, many have sought improved methods to characterize conditional crop-yield densities. While most have postulated the Beta as a flexible alternative to the Normal, others have chosen nonparametric methods. Unfortunately, yield data tends not to be sufficiently abundant to invalidate many reasonable parametric models. This is problematic because conclusions from economic analyses, which require estimated conditional yield densities, tend not to be invariant to the modeling assumption. We propose a semiparametric estimator that, because of its theoretical properties and our simulation results, enables one to empirically proceed with a higher degree of confidence.     

Stochastic Technology, Risk Preferences, and Adoption of Site-Specific Technologies

A model of farmer decision making is developed to determine the extent to which uncertainties about soil fertility and weather affect the value of site-specific technologies (SSTs) using jointly estimated risk and technology parameters. Uncertainty can lead risk-averse farmers to apply more fertilizers and generate more pollution than in the certainty case. Ignoring uncertainty and risk aversion would overestimate the economic and environmental benefits of SSTs and underestimate the subsidy required to induce adoption. Accounting for uncertainties and risk preferences might explain the low observed adoption rates of SSTs. Improving the accuracy of SSTs would increase the incentives for adoption.

Price rigidities and institutional variations in markets with posted prices

Summary Standard laboratory posted-offer markets respond slowly and incompletely to demand shocks. In these one-sided markets, where sellers control the setting of prices, very little information is transmitted via the process of exchange. For this reason, traders have trouble distinguishing randomness in their own experience from changes in market fundamentals. This paper reports the results of twelve laboratory markets conducted to assess whether some common variants to standard posted-offer rules can correct the adjustment deficiences. Although discounting, multiple postings and excess demand information all improve performance, we find that response remains poor, and efficiencies low.Support for this research was provided by the National Science Foundation (SBR 9319842 and SBR 9320044), and the University of Virginia Bankard Fund.

经济全球化时代的企业核心竞争力

随着经济全球化进程的加快，我国企业日益步入信息技术极速发展、技术升级日新月异、世界市场自由开放、各国竞争激烈残酷、机遇挑战同时并存的新环境。企业意欲在这样错综复杂的市场竞争中立于不败之地并谋求长期生存与稳步发展，就必须深刻认识到核心竞争力是其长期竞争优势的源泉，是其获得成功的关键要素。     

创新型企业组织形式的设计

创新型企业在组织构成上与传统企业有很大的不同，它是为了达到技术和产品创新的目的，在不同专业领域进行一定方式的分工和合作的一批高素质技术人员的集合。因此，在组织上，创新型企业就要不同于传统企业的直线职能式的组织结构。经研究，它应以项目组为组织的基本单元，建立矩阵式的组织结构，充分利用人力资源，灵活、快速地适应环境的变化。     

China’s Labor Market on Crossroad

I.IntroductionSincethelate1990s,China’slabor market has comeundergreat pressure,asreflected by anincreasing unemployment rate,and adeclining labor force participation rate.The causesofthe severe unemployment are threefold.First,due to the macro-economic downturn andrapid industrial structural change in the late1990s,state-owned enterprises(SOEs),whichlost their comparative advantage and competitiveness,have been unable to fully utilizetheir production capacity,and have become loss-makers.Se…     

电力商标分析及评估模型的构建

本文分析了电力商标的实质内涵，总结了电力商标的基本特征，在此基础上对商标的评估模型进行了创新构建，新建模型有两大特点：一是将商标收益分割为两部分计量；二是用强度系数进行了调整强化，为电力商标的评估提供一种新思路。     

浅谈落后山区人才现状及其对策

当今世界,人才资源已成为最重要的战略资源,人才不仅在国际竞争中越来越具有决定性意义,而且在国内竞争中也发挥着愈来愈重要的作用。从某种意义上讲,区域经济的竞争实际上就是人才的竞争。一个地区经济越发达,集聚的人才也就越多,而人才集聚得越多,也就越能促进当地发展。改革
