The labour income share and the relative price of investment in the US: an empirical investigation

Several studies argue that the recent decline in the secular trend of the labour income share is mostly driven by capital-embodied technological progress which is typically identified with trend reductions in the relative price of investment. In this paper, I use data from the United States to assess the nature of the relationship between trends in the labour share and the relative price of investment. Results from co-integration tests reveal that the share and the relative price of investment are most likely not co-integrated. However, co-variation tests indicate that both time series share a common stochastic component, and additional tests of structural breaks point at the presence of a common change in the mean or trend of both series. These results suggest that capital-embodied or investment-specific technological progress may have played an important role in the decline of the secular trend of the labour share.     

Anti‐immigration policy in the destination country and skilled–unskilled wage inequality in a source economy with or without unemployment

This paper is aimed at theoretically examining the consequence of the anti‐immigration policy adopted in the destination country on the skilled–unskilled wage inequality in a source nation using a couple of two‐sector, specific‐factor general equilibrium models in both the presence and absence of unemployment. Emigration requires incurring some capital cost for professional skill formation on the part of every prospective emigrant that adds to the opportunity cost of emigration. The authority of the destination country determines the number of visas to be granted and hence directly controls the magnitude of skilled emigration from the source country. In the migration equilibrium, the expected skilled wage income abroad is equal to the opportunity cost of emigration. In both the presence and absence of unemployment of unskilled labor, the outcome of the policy on the wage inequality crucially hinges on both the magnitude of the fixed cost of emigration and the technological factors. In the specific‐factor Harris–Todaro model, the degree of imperfection in the unskilled labor market is an additional factor. Finally, some policy recommendations have been made for protecting the interest of the poor unskilled workforce.     

The consequences of managerial indiscretions: Sex,lies, and firm value

Personal managerial indiscretions are separate from a firm's business activities but provide information about the manager's integrity. Consequently, they could affect counterparties’ trust in the firm and the firm's value and operations. We find that companies of accused executives experience significant wealth deterioration, reduced operating margins, and lost business partners. Indiscretions are also associated with an increased probability of unrelated shareholder-initiated lawsuits, Department of Justice and Securities and Exchange Commission investigations, and managed earnings. Further, chief executive officers and boards face labor market consequences, including forced turnover, pay cuts, and lower shareholder votes at re-election. Indiscretions occur more often at poorly governed firms where disciplinary turnover is less likely.     

长阳县发展旅游业与农民增收的关系研究

农民增收是新农村建设的一项重要任务,要从根本上解决农民增收问题,关键在于把农村剩余劳动力转移出来。在对湖北宜昌长阳土家族自治县的调研中发现,旅游业可以有效地实现劳动力的转移,走＂进厂不进城、离土不离乡＂的发展道路,使旅游业的发展与农民增收相得益彰。     

公共物品、分工演进与经济增长

在新兴古典经济学框架内,公共物品既能通过提高交易效率来促进分工演进并最终带来经济增长,也可通过改善劳动效率直接促进产出的增加,经济增长中的两难冲突发生于专业化经济和公共物品对劳动时间这一资源的争夺,资源的最终分配取决于三个重要的经济参数即专业化经济系数、公共物品的交易效率系数和劳动效率系数的大小和变化情况。文章最后从历史经验的角度来论证主要结论的正确性。     

Some Empirical Evidence of the Efficacy of Job Matching in Urban Labor Markets

Theory predicts that workers in cities are more likely to engage in job search, ceteris paribus, due to market efficiencies associated with greater job density. However, if job search is more efficient in urban markets, then the quality of a given job match should also tend to be higher in cities, ceteris paribus. Employed workers living in cities might then be expected to search less than their nonurban counterparts. In this latter instance, it is not city residency itself that makes search less likely, but rather the positive correlation between city residency and job match quality. Using data from the National Longitudinal Survey of Youth 1979, this prediction is confirmed: The estimated coefficient on an indicator of urban residency is found to be near zero and statistically insignificant in models of employed search that omit proxies for job match quality. When job match proxies are included in the models, the estimated coefficient on urban residency becomes positive and highly significant. This result suggests that workers are not only more likely to engage in employed search in urban labor markets, but also tend to find more productive job matches in cities over time.

Gender and Network Formation in Rural Nicaragua: A Village case study

Abstract

This contribution examines the relation between gender and network formation in rural Nicaragua in 2007 and studies differences in the structure and contents of men's and women's networks. Such differences are relevant, as network theory suggests that structural characteristics – as well as the contents of networks – strongly influence the type and amount of benefits generated. Through the application of dyadic regression techniques, this study examines the determinants of the size and socioeconomic heterogeneity of individual networks. Research findings suggest gender segregation of networks and considerable differences in the structure and content of men's and women's networks. These differences relate to the gendered division of labor and to women's time poverty in particular. Our results are relevant in a context where policy makers increasingly consider social networks an important policy tool. We caution against a gender-blind alignment on existing social networks and argue for detailed mapping and unpacking of social networks through a gender lens.     

就业流动、市场分割与行业收入差距分析

本文从就业流动视角出发,运用劳动力市场分割理论的分析范式,考察了垄断行业和竞争行业间的收入差距问题.研究发现行业间存在非对称的就业流动,影响国有垄断行业就业流动的因素主要体现为体制性特征,且其与其他行业间的收入差距明显,表明该行业与其他部门存在明显的市场分割特征;而对于非国有垄断行业来说,非经济性因素对其影响非常有限,虽然该行业和竞争行业间仍存在工资差距,但并不足以证明其与竞争行业存在市场分割.竞争行业内部同样存在收入差距,影响国有部门和非国有部门间流动的因素体现出市场性和体制性混合但偏向市场竞争的特征,表明市场化的改革推动了竞争行业走向公平竞争,但是福利待遇等非工资性收入差距仍是改革的难点.
