We develop a model explaining the consolidation patterns in the agricultural biotechnology industry. Among different consolidation and cooperation mechanisms, we consider collaborative and licensing agreements, joint ventures, acquisitions, and exchanges of ownership and spin-offs. The key results derive from the benefits of coordinated actions, distinction between transferable and nontransferable payoffs, the substitutability, complementarity, and the importance of the managers' noncontractible investments, and access and expansion of markets. Results from the model are used to examine the cooperation and consolidation activities for four major players in the agricultural biotechnology industry, DuPont , Dow Chemical , Monsanto , and Novartis . 相似文献

Modeling Conditional Yield Densities 总被引:2,自引:0,他引:2
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. 相似文献

听在人类语言交际活动中占有很重要的地位。听、说、读、写——外语学习的基本步骤中,听排第一位。随着高考、大学英语四、六级考试对听力理解,听力测试的要求,学生对其产生的心理障碍也随及增长,引发出被动心理现象,疲倦感觉现象和紧张,恐惧现象。培养和提高听力水平和听力能力,必须从理论上认识听力理解的过程,从心理上克服种种障碍。 相似文献

Rule l0b-5 of the 1934 Securities and Exchange Act allows investors to sue firms for misrepresentation or omission. Since firms are principal–agent contracts between owners – contract designers – and privately informed managers, owners are the ultimate firms’ voluntary disclosure strategists. We analyze voluntary disclosure equilibrium in a game with two types of owners: expected liquidating dividends motivated (VMO) and expected price motivated (PMO). We find that Rule l0b-5: (i) does not deter misrepresentation and may suppress voluntary disclosure or, (ii) induces some firms to adopt a partial disclosure policy of disclosing only bad news or only good news. 相似文献

Subsidised employment is an important tool of active labour market policies to improve the reemployment chances of the unemployed. Using unusually informative individual data from administrative records, we investigate the effects of two different schemes of subsidised temporary employment implemented in Switzerland: non-profit employment programmes (EP) and a subsidy for temporary jobs (TEMP) in private and public firms. Econometric matching methods show that TEMP is more successful than EP in getting the unemployed back to work. Compared to not participating in any programme, EP and TEMP are ineffective for unemployed who find jobs easily anyway or have a short unemployment spell. For potential and actual long-term unemployed, both programmes may have positive effects, but the effect of TEMP is larger. 相似文献

本文的基本观点是,企业文化是通过影响员工心理契约的形成而发挥作用的。本研究发现,企业文化是员工心理契约形成的更一般性的基础,企业文化的特征将决定员工心理契约的性质。我们认为,员工心理契约是一个平衡结构,员工责任和组织责任在内容和强度上都需要平衡。 相似文献

The expression “the bell curve” designs both a kind of statistical distribution and the title of a famous and controversial
book by Herrnstein and Murray. The first is so attractive that the second refers to it to give more credibility to its questionable
theories on intelligence. The point is that, during the 20th century, the bell curve has assumed a more and more important
role in psychological research and practice and have become both a reality and a myth. In the first case (reality) we can
assist to appropriate applications of a real useful statistical concept. In the second (myth) we can have two kinds of attitudes:
one attitude is typical of those researchers who search for normality in all their data and variables, just as Parsifal used
to search for the Holy Graal (we call this “the Parsifal attitude”); the other is typical of those researchers who give normality
for granted and act as if it were a Platonic Idea (we call this “the Plato attitude”). The article discusses the role of the
normal distribution in psychological research and practice and shows how it can be dangerous to treat the bell curve as a
God or an Idol. 相似文献
