This paper revisits the relationship between a country’s openness and its per capita income. Building on Frankel and Romer,
it argues that a dynamic econometric specification similar to the ones used in empirical growth studies better fits the theoretical
literature and also resolves some otherwise unresolved inconsistencies. The preferred econometric method is Blundell and Bond’s
system-GMM estimator, which allows dealing with measurement error, weak instruments, and time-invariant country-specific effects.
The findings confirm the existence of a strong effect of trade on income but fail to find evidence for trade as an independent
factor of divergence.

This paper examines a two-country, dynamic game model of pollution control in the presence of economic interactions between countries within a period, as well as the environmental interaction between periods (i.e., a change in the stock of global pollution). These economic interactions emerge because of changes in the terms of trade of polluting goods or the market share of domestic polluting industries. It is shown that if within-period externalities exist, a noncooperative equilibrium may result in a smaller stock of global pollution in the steady state than does international cooperation. Moreover, the properties of equilibrium paths depend on the direction and size of such externalities. In addition, trigger strategy equilibria that achieve the outcome of the collusive solution are examined. 相似文献

Advances in technology have impacted accounting careers with resulting changes in where, when and how accountants perform their job duties. In addition, employee attitudes towards, and need for, better work/life balance has led to more firms offering alternate work arrangements (AWA). Research suggests that AWA programs can lead to many benefits for both employers and employees. Despite the prevalence of these programs there are relatively few accountants working under these arrangements and concerns about work/life balance continue. This study examines factors that shape perceptions of the cost and benefits associated with the adoption and/or support of AWAs across work culture, gender and participation experience. Our results suggest that work environment had a significant effect on perceptions of AWAs. Public accountants perceived greater costs related to career advancement but correspondingly less concern about administrative issues than management accountants. We also found that accountants who have participated (or are currently participating in an AWA), perceived greater benefits and less concern for potential negative consequences to their careers than non-participants. Finally, women perceived greater benefits to result from participation in an AWA and men perceived correspondingly more costs. Regardless, both genders perceived that AWAs were not strictly a women's issue. These findings contribute to our understanding of alternate work arrangements and point to factors that must be addressed to increase the acceptance and success of these programs. 相似文献

The principal aim of this paper is to evaluate the impact of the future European high-speed train network on accessibility, by reducing time distance between places and modifying their relative location. We compare the current situation with that foreseen for the year 2010, according to the Outline Plan of the European High-Speed Train Network, in order to analyse which areas will most benefit from construction and improvement of the infrastructure. It is hypothesized that the high-speed train will certainly bring the peripheral regions closer to the central ones, but will also increase imbalances between the main cities and their hinterlands. A weighted average distance indicator is applied for this purpose. This measure identifies the spatial distribution of accessibility in the area of study, emphasizing the infrastructure effects, and locates accessibility changes at the European level. A Geographic Information System (GIS) has been used to carry out this study. 相似文献

国际贸易中的技术性壁垒及我国对策 总被引:1,自引:0,他引:1
李涛 《中国国土资源经济》2003,16(4):32-35
二十一世纪是全球经济一体化的知识时代 ,科学的巨大变革已经渗透于人类社会的方方面面 ,而国际贸易中的技术性壁垒则体现了贸易保护主义与科技相结合的作用。并且 ,这种非关税壁垒形式以其正义的外衣、巨大的影响力和借助科技的快速发展越来越成为国际贸易中不可忽视的保护手段。中国作为世界贸易组织的新成员更应在这方面进行研究 ,并制定相应的战略。 相似文献
