农牧户融入现代农业生产体系意愿影响因素研究——以岷江上游为例

[目的]分析岷江上游地区农牧户融入现代农业生产体系意愿的影响因素及其内部异质性。[方法]文章运用Logit模型,基于岷江上游地农牧户调研数据,选取农牧户认知水平、社会资本、邻里效应等五个方面19个指标分析其对农牧户融入现代农业生产体系意愿的影响。[结果](1)认知水平对农牧户融入现代农业生产体系的意愿有显著的正向影响;这种影响不存在农牧行业异质性。(2)换工行为显著提升了农牧户融入现代农业生产体系的意愿(3)政策环境因素对于提升农牧户融入现代农业生产体系的意愿具有重要影响。[结论](1)提高农牧户对现代农业生产体系的认知水平是促进岷江上游地区农牧户融入现代农业生产体系的根本途径。(2)农牧户的换工行为已经不再是一种简单劳动交换行为,而演变为现代农业生产方式的演示和交流活动。(3)岷江上游地区的现代农业发展战略不能仅仅就农业而谈农业,而要通过教育、医疗和基建等各方面的协同推进,全面增强农牧户对现代生产方式的认知水平,为农牧户融入现代农业生产体系提供基本条件。     

企业内部二级库存系统中库存策略比较研究

针对随机需求下企业内部由中心仓库和下设的地区仓库组成的二级库存系统,运用推动式库存模型通过对相同服务水平下有中心仓库和无中心仓库两种情况的成本进行比较分析,来确定在企业内部二级库存系统中是否也设立中心仓库,以供决策者对库存策略进行合理规划。     

Innovation strategies and firm performance: Simple or complex strategies?

This paper analyzes the effect of various innovation strategies (ISs) of firms on their future performance, captured by labor productivity. Using five waves of the Community Innovation Survey in Sweden, we have traced the innovative behavior of firms over a decade, that is, from 2002 to 2012. We defined ISs to be either simple or complex (in various degrees). We call an IS a simple IS when firms engage in only one of the four types of Schumpeterian innovations, that is, product, process, marketing, or organizational, while a complex IS is when firms simultaneously engage in more than one type. The main findings indicate that those firms that choose and afford to have complex ISs are better off in terms of their future productivity in comparison with those firms that choose not to innovative (base group) and also in comparison with those firms that choose simple ISs. The results are mostly robust for those complex innovators that have a higher degree of complexity and also keep the balance between technological (product and process) and non-technological (organizational and marketing) innovations.

The first-order approach when the cost of effort is money

We provide sufficient conditions for the first-order approach in the principal-agent problem when the agent’s utility has the nonseparable form u(y−c(a))$u(y-c\left(a\right))$ where y$y$ is the contractual payoff and c(a)$c\left(a\right)$ is the money cost of effort. We first consider a decision-maker facing prospects which cost c(a)$c\left(a\right)$ and with distributions of returns y$y$ that depend on a$a$. The decision problem is shown to be concave if the primitive of the cdf of returns is jointly convex in a$a$ and y$y$, a condition we call Concavity of the Cumulative Quantile (CCQ) and which is satisfied by many common distributions. Next we apply CCQ to the distribution of outcomes (or their likelihood-ratio transforms) in the principal-agent problem and derive restrictions on the utility function that validate the first-order approach. We also discuss another condition, log-convexity of the distribution, and show that it allows binding limited liability constraints, which CCQ does not.     

The relationship between organizational level and workplace friendship

This study examines the effect of organizational level on workplace friendship, which remains unclear in the organizational literature regarding interpersonal relationships. As was hypothesized, the result from a survey of 288 Taiwanese employees revealed that individuals at higher organizational levels perceived less workplace friendship. The finding does not support the argument that higher levels are presumed to have more workplace friendship in view of their capability of resource-supplying or their being in the centrality of working relationships/networks in their organizations. The workplace of organizational higher levels, and the situations for the finding are also discussed.
