Summary.  This paper examines the relationship between specialization and the use of money in two versions of the search-theoretic monetary model. The first version establishes a surprising result that specialization is more likely to occur in a barter economy than in a monetary economy. The result is reversed in the second version where a different specification of preferences is adopted to limit the scope of barter. This contrast between the results provides a concrete illustration of the general argument that money encourages specialization only when it enlarges the extent of the market.

Using two large samples for 1988 and 1995 we decompose the Gini coefficient of household income according to type of income with the purpose of analyzing reasons for the rapid increase of inequality. The results show that the change in relative size of money income and its changed profile are found to be the major processes behind the rapid increase of income inequality in rural China. Changes in housing allocation and an increased number of retirees in combination with higher benefits have made inequality increase in urban China and in China as a whole. JEL classification: D31, P27.  相似文献

Announcements of syndication loans increase borrowers' shareholder wealth if they are revolving credit agreements but not if they are term loans. Share price responses to revolving credit announcements are positive and significant, whereas the wealth effect for term loans is negative and significant. The results show that announcements from both the financial press and commercial information providers can affect borrower share price reaction. Overall, single syndication announcements appear to be more newsworthy than multiple announcements reported in the financial press, and we find evidence of information leakage, post‐announcement drift, or both.  相似文献

The authors show that an increase in international borrowing increases specialization and unemployment in a small open economy that is subject to terms‐of‐trade risks. The economy has a production advantage in the export sector. However, the size of the export sector is limited by the available funds. To insure workers against income fluctuations arising from terms‐of‐trade risks, firms in the export sector offer workers a stable wage rate with the possibility of unemployment. An increase in international borrowing increases specialization in the export sector, which leads to higher unemployment when the terms‐of‐trade shock is bad. A state‐contingent price subsidy can reduce unemployment without inefficiently reducing specialization. The results are robust to the introduction of risk‐averse firms.  相似文献

In this research, we examine the role of two motivational forces associated with creation of electronic word-of-mouth (eWOM): regulatory focus and collective dissonance. Our studies show that generation of eWOM is enhanced by regulatory fit, while traditional WOM is dominated by the negativity effect. In study 1A, we show that prevention-focused consumers produce stronger intentions to post eWOM when they undergo a negative compared to a positive service experience. In study 1B, we find that promotion-focused consumers are more likely to post eWOM in reaction to a positive service experience when one's self-construal is independent. The final study shows that due to collective dissonance, consumers have greater intentions to create eWOM when their experiences are inconsistent with others' postings. We discuss the implications of these results for the development and management of eWOM communication in virtual communities.  相似文献

近年来产品供应链管理得到了广泛的关注,而产品供应链强调的是产品从供应商到分销商乃至最终客户的流程活动,基于此很多供应链信息技术的运用都是支持这一活动过程的,然而,随着经济全球化以及市场变化的加剧,使得企业越来越从产品供应链转向信息化为基础的价值网络。通过安吉物流以及苏宁电器的供应链信息化运作为研究对象,揭示了新时代价值网络管理的特征以及组织方式。指出价值网络管理的运行不仅是供需之间的产品经营和信息的协同,更是计划、知识、流程和投资行为的协同化,此外在组织方式上,则是以服务为中心、供需互动为手段、链式、辐射式、星座式创新为基础的综合管理体系。  相似文献
