This research is trying to shed light on two myths that are usually widespread: the first one being the idea of the academic economist as a neutral scientist finding uncontestable consensual truths, thanks to uncontestable empirical methods, the second, the idea of the central banker as a Weberian neutral bureaucrat setting aside personal beliefs to act mechanically for the common good. Deconstructing this ‘neutrality illusion’, this work argues that economics is actually a divided and ideologically marked discipline despite its aim at natural-science-type-legitimacy. It argues in a related discussion that such ideological bias also impedes a purely neutral conduct of monetary policy, undermining the very idea of central bank independence. Linking these two arguments, it argues that graduate training in economics is the first place for the formation of biased preferences, because of the substantial ideological sorting that exists across universities. Using a unique database on FOMC members’ votes and ideology, the paper tests this idea empirically and despite unavoidable caveats, finds robust evidence of a systematic impact of the ideological features of their alma mater on FOMC members’ voting behaviour – impact that we found more important than the other traditional determinants of central bankers’ actions. 相似文献

This paper investigates the extent to which cross-country differences in aggregate participation rates can be explained by differences in tax-benefit systems. We take the example of two countries, the Czech Republic and Hungary, which – despite a lot of similarities – differ markedly in labour force participation rates. Using comparable individual-level labour supply estimates, we simulate how the aggregate participation rate would change in one country if the other country’s tax and social welfare system were adopted. The estimation results for the two countries are quite similar, suggesting that individual preferences are essentially identical in the two countries. The simulation results show that about one-third of the difference in the participation rates of the 15–74 year-old population and more than two-thirds of the participation of the prime-age population can be explained by differences in the tax-benefit systems. 相似文献

We believe that what most authors have in mind when referring to the “most redistributive country” is a tax and transfer schedule that is most redistributive across all pre-tax and transfer income distributions. In order to measure each country's tax and transfer redistribution according to the same baseline, we suggest using the transplant-and-compare method of Dardanoni and Lambert (2002, Journal of Public Economics 86, 99–122) to establish a common base. The redistributive effects of countries’ tax and transfer schedules are illustrated by employing microdata on eight countries from the Luxembourg Income Study (LIS). Of these eight countries, Finland is found to be the most redistributive country, according to the common base method. 相似文献

作为推动国民经济增长和促进社会稳定的基础力量,中小企业在市场中扮演着最活跃的经济主体。与大企业相比,中小企业有其鲜明的成长特征,从动态演进视角选取体量规模、生命周期、要素需求三个维度,系统探讨了中小企业的差异化特征。结论显示:体量规模特征反映在个体与群体以及经济板块之间;生命周期特征体现在死亡陷阱和空间格局演变上;要素需求特征会根据阶段创新内容的不同做出适时调整。 相似文献

教育类企业具有轻资产性、服务滞后性、产品同质性三项特质,这些特质一方面导致了企业缺乏上市募集资金的动机,另一方面又促使企业上市以解决同消费者信息不对称的难题,降低消费者选择成本,提升企业财务绩效。研究发现:上市行为本身具有的品牌效应产生的正面作用,可以抵减盈余管理带来的负面作用,使得教育类企业新三板上市后业绩不再变脸。而将这一品牌效应剥离后发现,企业依然会出现业绩变脸,从而发展了基于盈余管理的IPO效应理论。进一步将教育类企业分成强弱特质两类,发现强特质教育类企业的上市行为可以更有效地促进财务绩效的提升,从而为延伸到其他具有教育类企业特质的行业提供了可能性。 相似文献

The distinct urbanization process of China has attracted worldwide attention because of its impressive speed, massive scale, and policy intervention. However, the interrelationship between urban expansion and government policies is still not well understood. The Pearl River Delta Urban Agglomeration of China is the first national pioneering urbanization area since the implementation of the policy “Reform and Opening-up” in the late 1970s. Here we compared the spatial and temporal patterns of urbanization in two leading cities of the Pearl River Delta (i.e., Guangzhou and Shenzhen, the provincial capital and the first Special Economic Zone of China, respectively) from 1975 to 2015, using Landsat data integrated with urban growth and landscape metrics analysis, and examined possible footprints of major economic and urbanization policies. Our results illustrated that urban land areas in both Guangzhou and Shenzhen have experienced magnificent annual growth rates at 8.1% and 11%, respectively between 1975 and 2015. On average, Shenzhen witnessed substantially higher urban growth rate than Guangzhou during the past four decades, particularly in the initial period (1978–1990) when the Reform and Opening-up policy was launched and Shenzhen was designated as the first Special Economic Zone in China in the late 1970s. However, the speed of urban expansion in Shenzhen became considerably lower than Guangzhou from 2005 to 2015, subject to physical conditions and a series of urban land use policies. Both cities showed a generally similar dynamics of urban growth forms with leapfrogging as the predominant type of urban growth at first and then edge-expansion while the contribution of infilling in Shenzhen was higher than that in Guangzhou, especially since 2005. The urbanization processes characterized by landscape and urban growth metrics revealed that a diffusion-coalescence-diffusion-coalescence process was identified for Guangzhou, while Shenzhen was generally consistent with the diffusion-coalescence urban growth hypothesis. 相似文献

AbstractPerceived work-related stress has increased notably in recent years, reducing individuals’ well-being and increasing organizations’ and economies’ costs. This study focuses on worktime control as a key approach to reducing work stress, as the extant research on its effects reports inconsistent results. The study argues that comparisons play a major role in how work stress, conceptualized as effort-reward imbalance, occurs. Ordinary least squares is used to test hypotheses with a sample of 1721 employees from Germany to determine whether employees’ prior worktime control and employees’ referents’ worktime control affect the relationship between worktime control and work stress. Results show that (1) worktime control is negatively associated with the experience of work stress, (2) employees’ prior worktime control moderates the relationship between worktime control and work stress, and (3) there is no moderating effect of employees’ referents’ worktime control. The results are discussed in light of gift-exchange theory and related empirical findings. 相似文献

在异质性企业理论框架下,引入教育供给因素,将其视为社会型基础设施与交通基础设施进行比较研究;通过合并基础设施数据与工业企业数据分析两类基础设施对企业出口的异质性影响。实证研究显示:不同类型基础设施对企业出口产生不同影响,其中地区教育供给对企业出口促进作用显著,交通基础设施对企业出口作用并不稳健;不同基础设施对沿海和内陆地区企业出口有差异化影响;在产业特征框架下,基础设施供给对密集使用某类基础设施的企业出口促进作用明显。地方政府应重视社会型基础设施的贸易促进作用,调整地区基础设施投资结构。 相似文献

Observing others receive preferential treatment has been found to provoke bystanders' negative reactions. However, seeing others treated better may also inspire bystanders to increase their repatronize intentions. Drawing upon theories of social comparison and goal-setting, this study investigates the condition when watching another's preferential treatment acts as a catalyst to enhance bystanders' repatronize intentions and the mechanism by which the constructive effect appears. The results indicate that when bystanders witness similar others' preferential treatment and believe that they can attain comparable treatment, their goal-setting motivation is more activated and consequently they are more committed to goal-relevant behavior (i.e., repatronize intentions). 相似文献
