Lumpy Investment and Corporate Tax Policy

In the presence of both convex and nonconvex capital adjustment costs in a dynamic general equilibrium model, corporate tax policy generates both intensive and extensive margin effects via the channel of marginal Q. Its impact is determined largely by the strength of the extensive margin effect, which, in turn, depends on the cross‐sectional distribution of firms. Depending on the initial distribution of firms, the economy displays asymmetric responses to tax changes. Moreover, an anticipated increase in the future investment tax credit reduces investment and adjustment rate initially.     

基于城镇化视角下休闲农业发展路径分析——以山东省为例

作为我国经济结构的不断调整与我国城乡差距的逐步扩大等相关城乡问题的有效解决方案,城镇化建设对于我国农村地区经济社会的健康发展与缩小目前我国城乡差距,实现我国城乡协调发展至关重要。随着我国城镇化进程的不断加快,如何有效利用城镇化所带来的机遇,如何通过城镇化建设有效推进我国农村产业结构调整,实现农村经济的快速发展是在我国城镇化背景之下农村经济发展需要面对与急需解决的重大课题。休闲农业作为一种区别于传统农业的先进的农业生产模式其对于我国农村产业结构的调整至关重要。作为我国的农业大省与人口大省,如何实现休闲农业的长期健康发展是山东省在城镇化建设进程中继续解决的重要课题。文章通过文献查阅与实地调研相结合的方法对目前城镇化背景下山东省休闲农业发展路径进行系统研究并再对其中存在的诸多问题进行细致分析基础上提出相应的解决方案,旨在在城镇化快速发展背景下为山东省休闲农业的长期健康发展提供一定的理论与实践借鉴。     

江苏省虚拟水贸易结构调整研究

基于江苏省2012年投入产出表及水资源公报的统计数据,运用修正后的投入产出模型,定量计算江苏省贸易用水强度、虚拟水净输出量,并通过调整贸易结构,最大化实现节水效应。研究表明:2012年江苏省虚拟水贸易整体上呈现净流入,有利于节约省内水资源;从贸易额调整来看,在设定的5%、10%、15%3个调整幅度的基础上改变传统的贸易输出、输入结构,化学产品、煤炭采选产品部门出现大规模节水效应,随着调整幅度的增加,净输出量大的部门节水效应越来越大。江苏省虚拟水贸易是当前实现资源节约与经济发展的重要方式。

Quantitative easing and the loan to collateral value ratio

We study optimal monetary policy in a New Keynesian model at the zero bound interest rate where households use cash alongside house equity borrowing to conduct transactions. The amount of borrowing is limited by a collateral constraint. When either the loan to value ratio declines or house prices fall, we observe a decrease in the money multiplier. We argue that the central bank should respond to the fall in the money multiplier and therefore to the reduction in house prices or the loan to collateral value ratio. We also find that optimal monetary policy generates a large and persistent fall in the money multiplier in response to the drop in the loan to collateral value ratio.     

When the going gets tough: the influence of expatriate resilience and perceived organizational inclusion climate on work adjustment and turnover intentions

Abstract

Despite the strong evidence for the beneficial influence of resilience for employee stress resistance in domestic settings, the construct has not received much attention in the expatriation literature, where stress is considered a major factor for expatriates’ poor cross-cultural adjustment and turnover. Drawing upon conservation of resources theory, the present study examines resilience as an antecedent of expatriate work adjustment and turnover intentions. Furthermore, this study investigates the moderating role of perceived organizational inclusion climate as a resource-protecting organizational factor. Results from a survey of 175 expatriates in South Korea indicate that resilience is positively related to expatriate work adjustment and that these positive effects are more pronounced when expatriates perceive their organizational climate to be highly inclusive. Furthermore, findings suggest that work adjustment mediates the effects of resilience on turnover intentions and that this mediation is moderated by a perceived organizational inclusion climate. Implications for theory and practice are discussed.     

Leisure,international retirement migration,and retirement adjustment: insights from the best exotic marigold hotel movies

ABSTRACT

International retirement migration (IRM) is a growing phenomenon linked to increased longevity, early retirement, and improved financial status. Encompassing both travel and leisure experiences, IRM is a topic relevant to both tourism and leisure studies. By analysing the fictional movie series The Best Exotic Marigold Hotel (2012) and The Second Best Marigold Hotel (2015) from psychological, gerontological, and sociological theoretical perspectives, this paper examines motivation, goal setting, continuity and change, and identity development in IRM experiences within tourism and leisure contexts. This paper (a) identified motivations for IRM as finance, romantic relationships, social relations, self-esteem, self-fulfilment, and social norms; (b) in turn, time perception and attitude influence IRM emigrants’ priority and emotional fulfilment; (c) innovation extricates IRM emigrants from role loss and facilitates role change; and (d) IRM emigrants experience various identity development processes. A conceptual framework for IRM is proposed that purports to explain the IRM experience process and indicates that such an understanding of IRM should incorporate psychological, gerontological, and sociological perspectives.
