State‐contingent analysis of farmers’ response to weather variability: irrigated dairy farming in the Murray Valley,Australia

The agricultural sector is commonly regarded as one of the most vulnerable to climate change. Current understanding of the impact of climate change on this sector relies on the underlying assumptions about farmers’ possible responses to weather variability, including changes in crop choice, input combinations and land management practices. Many previous analyses rely on the implicit (and restrictive) assumption that farmers operate under a fixed technology set across different states of nature. This assumption, represented through stochastic production or profit functions, is commonly made but seldom tested and may understate farmers’ responses to climate change if state‐contingent production technologies are, in reality, more flexible. The potential for farmers to adapt production technologies in response to unforeseen events is at the core of the state‐contingent approach. Advanced in Chambers and Quiggin (2000), the theory contends that producers can manage uncertainty through the allocation of productive inputs to different states of nature. In this article, we test the assumption that farmers’ observed behaviour is consistent with the state‐contingent production theory using farm‐level data from Australia. More precisely, we estimate the milk production technology for a sample of irrigated dairy farms from the southern Murray–Darling Basin over the period from 2006–2007 to 2009–2010.

新制度经济学视角下的中国农地制度变迁：回顾与展望

研究目的:分析总结中国农地制度变迁的路径特征、决定条件和影响因素,并展望进一步研究方向。研究方法:文献分析法。研究结果:(1)改革开放以来的中国农地制度变迁呈现出一个较清晰的路径,即改革始终沿着市场取向、明晰产权、稳定地权的方向演进;(2)农地使用权制度改革的成功源于诱致性变迁与强制性变迁的结合,即弹性的中央政策制定、渐进式的地方实施以及具有学习效应的农户认知三者的有机互动,并体现出制度变迁的"共生演化"特征及其蕴含的"适应性效率";(3)新制度经济学是解释中国经济改革和农地制度变迁的有效工具,然而由于经典的新制度经济学本质上的静态性以及国家理论的缺乏,难以对现实世界的各类制度变迁给出一般化的解释。研究结论:基于经典的新制度经济学,进一步整合行为经济学、机制设计理论、演化博弈论等理论工具,超越"强制性—诱致性变迁"二分法,构建一个真正动态的制度变迁模型是一个重要研究方向。     

The Conflicted State and Agrarian Transformation in Pink Tide Venezuela

Can radical political‐economic transformation be achieved by electoral regimes that have not thoroughly reconstructed the state? Contemporary Venezuela offers an optimal venue for examining this question. The Chavista movement did not replace the previous state: instead, its leaders attempted to reform existing state entities and establish new ones in pursuit of its transformation agenda. It has also used its oil wealth to support cooperatively‐oriented economic activity, without necessarily fundamentally altering the property structure. Thus, the social change‐oriented political economy exists alongside the traditional one. Focusing on agrarian transformation, we examine ethnographically how these factors have impacted the state's capacity to attain its goal of national food sovereignty. We find that the state's ability to accomplish this objective has been compromised by lack of agency‐level capacity, inter‐agency conflict and the persistence of the previously‐extant agrarian property structure. These dynamics have influenced the state to shift from its initial objective of food sovereignty to a policy of nationalist food security.     

How perceived empowerment HR practices influence work engagement in social enterprises – a moderated mediation model

Abstract

Drawing insights from the group engagement model and self-determination theory, our research explored the role of perceived empowerment human resource (HR) practices in the hybrid organizational form of social enterprise in China. Based on two studies, this paper developed and examined a moderated mediation model, linking perceived empowerment HR practices, identification motivation, work engagement, and authority work value. Specifically, in Study 1 we found perceived empowerment HR practices increased employees’ work engagement through enhancing employees’ identification motivation. In Study 2, we adopted a two-wave design to duplicate and extend this mediation model. A moderator, employees’ authority work value, was found to weaken both the mediation relationship, and the positive relationship between perceived empowerment HR practices and identification motivation. This study broadens the understanding of what social enterprises look like in alternative contexts, while providing an opportunity to explore how a HRM mechanism and its boundary condition function in large social enterprises in China.

Destination management organizations and destination marketing: adopting the business model of e-portals in engaging travel agents

ABSTRACT

Destination management organizations (DMOs) have an important role in engaging stakeholders in collaboration. Collaborating with stakeholders is useful for both stakeholders and destinations. However, it takes time and needs rigorous coordination to avoid conflicts with stakeholders. This study measures travel agencies’ attitudes towards engaging in online collaboration with DMOs for marketing purposes. It incorporates collaboration and technology acceptance models to predict the attitudes and intentions of travel agents using structural equation modeling. Data were collected from travel agents in Cairo, Egypt, using the random sample technique. This study will be useful for travel and tourism stakeholders and governmental marketing bodies.     

How middle managers manage the political environment to achieve market goals: Insights from China's state‐owned enterprises

Research summary: Although the middle management literature has identified various bridging roles performed by middle managers in the market environment, it is relatively vague about whether and how they manage the political environment to achieve market‐related goals. In an inductive field study of four large state‐owned enterprises based in mainland Communist China, operational middle managers were found to take an active role in dealing with political actors to achieve market efficiency in their local environments, performing two distinct bridging strategies. Our field study suggests that middle managers are better equipped than their bosses (top executives) as well as their subordinates (frontline employees) to perform the bridging function between competing market and political imperatives in various local settings. Managerial summary: For firms that operate in diverse geographies, it is challenging for a handful of top executives to deal with numerous political actors. This burden could be shared with operational middle managers, who play a bridging role by drawing on their operational knowledge and local networks. Our research on middle managers who work under the scrutiny of political actors in China found that they bridge market and political ideology by conveying common features that seem legitimate to both. They also bridge market goals and political actors with personal affect. Compared to top executives and frontline employees, middle managers have unique advantages in performing these bridging functions. Firms can enhance their strategy execution ability by training middle managers in dealing with political actors in diverse contexts. Copyright © 2016 John Wiley & Sons, Ltd.     

The impact of mood states and surprise cues on satisfaction

Mood effects have been studied in consumer behavior literature, but prior research investigating the joint impact of mood and surprise on satisfaction is scant. To bridge this gap, this study examines the relationship among these three constructs. We manipulated customers’ pre-consumption mood and provided surprise cues with hypothetical scenarios in a 2 by 2 factorial design in a restaurant setting. The results show that a positive surprise yields high satisfaction without a significant effect from customers’ pre-consumption mood. Conversely, with a negative surprise, customers in a negative pre-consumption mood indicate lower satisfaction than those in a positive mood.
