Drivers of cropland abandonment in mountainous areas: A household decision model on farming scale in Southwest China

Cropland abandonment has emerged as a prevalent phenomenon in the mountainous areas of China. While there is a general understanding that this new trend is driven by the rising opportunity cost of rural labor, rigorous theoretical and empirical analyses are largely absent. This paper first develops a theoretical model to investigate household decisions on farming scale when off-farm labor market is accessible and there is heterogeneity of farmland productivity and distribution. The model is capable of explaining the hidden reasons of cropland abandonment in sloping and agriculturally less-favored locations. The model also unveils the impacts of heterogeneity of household labor on fallow decisions and the efficiency loss due to an imperfect labor market. The model is empirically tested by applying the Probit and Logit estimators to a unique household and land-plot survey dataset which contains 5258 plots of 599 rural households in Chongqing, a provincial level municipality, in Southwest China. The survey shows that more than 30% of the sample plots have been abandoned, mainly since 1992. The econometric results are consistent with our theoretical expectations. This work would help policy-makers and stakeholders to identify areas with a high probability of land abandonment and farming practice which is less sustainable in the mountainous areas.     

What's in a broken promissory obligation? Developing and testing a multiple component form measure of psychological contract breach

While the literature has suggested the possibility of breach being composed of multiple facets, no previous study has investigated this possibility empirically. This study examined the factor structure of typical component forms in order to develop a multiple component form measure of breach. Two studies were conducted. In study 1 (N = 420) multi-item measures based on causal indicators representing promissory obligations were developed for the five potential component forms (delay, magnitude, type/form, inequity and reciprocal imbalance). Exploratory factor analysis showed that the five components loaded onto one higher order factor, namely psychological contract breach suggesting that breach is composed of different aspects rather than types of breach. Confirmatory factor analysis provided further evidence for the proposed model. In addition, the model achieved high construct reliability and showed good construct, convergent, discriminant and predictive validity. Study 2 data (N = 189), used to validate study 1 results, compared the multiple-component measure with an established multiple item measure of breach (rather than a single item as in study 1) and also tested for discriminant validity with an established multiple item measure of violation. Findings replicated those in study 1. The findings have important implications for considering alternative, more comprehensive and elaborate ways of assessing breach.     

Cultivating Ecological Knowledge for Corporate Sustainability: Barilla's Innovative Approach to Sustainable Farming

In this paper, we link three theoretical perspectives – organizational knowledge, ecological knowledge and social–ecological systems – to derive new conceptions of multi‐disciplinary, multi‐tier, sustainability‐oriented knowledge. Our study examines how collaboration between pasta‐producer Barilla, the farmers/smallholders supplying the firm and scientists generated sustainability practices in the agri‐food industry by creating transformative ecological, technical and scientific knowledge. In 2010, Barilla initiated a sustainable farming project to significantly reduce the environmental impact of cultivating durum wheat, its most important raw material. Core components included replacing monoculture with crop rotation, collectively creating innovative approaches that support farmers’ decision making and generating widely accessible guidelines for sustainability‐oriented cropping knowledge and practices. These collaborative efforts initiated profound transformations within and beyond the organization's boundaries via increased production yields, reduced environmental impacts and improved sustainability of farming practices, which generated economic, social and ecological benefits for farmers, surrounding communities and the firm.

IT运维外包中外派人员组织归属感的影响因素研究——基于心理契约理论的多案例研究

现在越来越多的客户将其部分或全部的IT运维工作交给外部的专业服务提供商。IT外派人员长期在客户的现场提供服务,这也导致了外派人员对母公司缺乏组织归属感。本文选择了四个涉及IT外派人员的IT运维外包项目进行案例研究,试图探寻影响外派人员对母公司组织归属感的影响因素。本文发现影响外派人员组织归属感的因素主要包括沟通、公平、员工关怀和稳定预期,但是在不同的心理契约情境下影响外派人员组织归属感的因素各不相同。     

心理契约违背对饭店顾客忠诚的影响——服务补救策略的调节效应

针对服务企业普遍面对的服务补救低效与顾客忠诚保持的挑战,文章基于心理契约与前瞻性服务补救理论,构建了顾客心理契约违背、服务补救和顾客忠诚间关系的分析框架,实证分析了心理契约违背对顾客忠诚的作用机理,并检验了服务补救策略对这一关系的调节效应。通过对262名饭店顾客的问卷调查,采用回归分析法处理数据,研究结果表明:心理契约违背两个维度与饭店顾客忠诚两个维度均呈显著负相关关系,顾客心理契约违背程度越高,顾客忠诚度越低;服务补救在心理契约违背与饭店顾客忠诚的关系中起到部分调节作用,即当企业服务出现失误而使顾客感知心理契约违背发生时,如果能采用恰当的服务补救策略,可以降低心理契约违背对顾客忠诚的负面影响。     

Impact of contracts in high yielding varieties seed production on profits and yield: The case of Nepal

Nepal’s population continues to grow, but the agricultural sector’s performance remains almost stagnant. This has led to a decline in the per capita availability of food. Increasing agricultural productivity is the key to agricultural growth, and one strategy for increasing agricultural productivity is to use improved seeds. This study investigates the impact of contract farming (CF) in high yielding varieties (HYV) of paddy seed production on costs, yield, and profits of smallholder farms in Nepal. Using farm-level data and a non-parametric propensity score matching estimator, the study finds a significant positive impact of contract HYV seed farming on revenues, profits, and yield, and a significant negative impact on total costs of production. Additionally, very small farms (⩽0.43 ha) with CF in HYV paddy seeds tend to gain the most when it comes to yield per hectare. Our estimates reveal that the average smallholder household in Nepal engaged in CF with input conditions receives higher profits. However, farmers engaged in CF with output conditions tend to have higher yields but smaller profits. Finally, farmers engaged in CF in HYV paddy seeds with both input and output conditions have the highest yield gains and significantly higher profits.     

顾客集中与管理层治理——基于薪酬契约和代理成本的视角

本文以创业板上市公司为研究样本，从薪酬契约和代理成本的视角，检验了顾客集中与管理层治理的关系。实证分析结果显示，顾客集中度与高管薪酬和代理成本存在显著负相关关系。结果表明：顾客集中显著影响公司薪酬契约，顾客集中降低了高管薪酬；顾客集中降低代理成本，减轻管理层代理冲突问题。这些研究结论丰富了公司治理的理论内容，同时对于缓解公司代理冲突、改善公司治理矛盾具有重要的现实意义。

IT外包的投资、再谈判机制分析

本文从IT承包商(vendor)和客户(client)的角度考虑去设计最优契约。由于客户方的需要,或者是由于契约的不完全性导致契约经常需要再谈判,而且由于契约修改后的执行问题也可能引起法律诉讼,因此对于如何决定事前的投资、谈判利润分配和契约诉讼的赔偿都是一系列要解决的问题,本文正是根据这些问题的提出而逐步展开的。
