Net job creation in the US economy: lessons from monthly data, 1950–2011

This article studies the monthly net job creation (NJC) at the aggregate and the sectoral levels in the United States over the period 1950 to 2011. The article has few important findings. First, NJC did not show a significant trend over the last six decades, which led to a fall in the NJC rate. Second, NJC was very volatile and it could change course even in the span of 1 month. Third, there was no clear pattern about the co-movement between NJC and the change in the unemployment rate. Fourth, the averages of total NJC and private NJC since late 2010 were significantly higher than their respective historical averages and the volatility in NJC since the end of the Great Recession was not unusual by historical standards. Fifth, while the evidence about the effects of the 2009 American Recovery and Reinvestment Act on employment is inconclusive, some sectors appeared to benefit from it. Finally, the most frequent drop in the unemployment rate was by 0.1%, and drops of more than 0.2% should not be highly expected.     

Dilemmas of Social Reform (Poverty and Community Action in the United States)

During the last thirty years, one of the most remarkable trends in Western Europe and North America has been the increase in women’s labor force participation rates. However, there has been considerable variation among countries; rates in Southern European countries are markedly lower than in other regions. Standard welfare state regime typology is unable to explain this outcome. This paper tackles the issue by examining the institutional determinants of employment decisions in Spain. Family policies and tax policies greatly influence the labor force participation of women by either promoting or discouraging the employment of mothers. However, these policies do not affect women in the same way. Of particular importance is whether women can claim benefits on the basis of their citizenship, or whether their status as wives or mothers is the link to benefits. By pursuing this line of analysis, the paper explains the low female labor force participation in Spain, providing an important contribution to the welfare state regime literature.     

How to estimate market concentration given grouped data

A novel method is proposed of estimating market concentration for the census case in which firms are grouped into size classes and all that is known about the firms in each category is their number and aggregate size. The formula arises as a way of applying an alternative expression for the concentration ratio based upon the original and first moment size distributions of firms. The semi-parametric technique, which includes a method of interval as well as point estimation, is derived, applied and validated using actual and simulated data. It is anticipated that the estimator will be of use in competition analysis as well as in academic research.     

快速城镇化对山东省粮食生产的挑战

随着经济的快速发展,中国城镇化水平不断提高。在快速城镇化发展过程中,大量耕地资源被城市建设占用,大批农村劳动力进入城市,农业水资源紧张态势日趋严峻,农业产业结构调整使粮食作物种植面积不断减少,这些都对粮食生产和粮食安全产生了不利影响。因此,要协调好城镇化发展和粮食生产的关系,合理规划城镇用地,以保障粮食生产及安全。     

Firm Performance and Women on the Board: Evidence from Spanish Small and Medium-Sized Enterprises

ABSTRACT

This study examines gender diversity on boards of directors in a sample of nonfinancial Spanish small and medium-sized enterprises (SMEs) for 2003–8, finding that the probability of women on the board increases with firm performance, defined as return on assets, and family ownership, but diminishes with corporate ownership and firm risk. It also finds, when examining the full sample, a positive effect of the presence of women board members on firm performance. The study also obtains a similar positive effect in most subsamples, including in firms with corporate ownership, where family connections play less role in the election of board members, and in firms in the secondary and tertiary sectors, which are characterized by having greater proximity to final consumers than those in the primary sector.     

Gender Employment Disparities,Financialization, and Profitability Dynamics on the Eve of Italy's Post-2008 Crisis

This study explores aggregate profitability in Italy from 1994 to 2008 in its connection with structural change and gender employment disparities. Using decomposition analysis, the study finds that aggregate profit rate declined, but the profit share did not. Male variables – such as earnings, output, employment, and working hours – tended to have more weight than female ones in explaining aggregate outcomes. Structural change also played a major role, as the economy specialized in sectors with falling real wages and wage shares, especially the financial sector and construction. Further falls in the wage share and widening wage gaps may not guarantee a rise in profitability. This result entails that “neo-mercantilist” approaches to solve the crisis might only prepare the next crisis, while a coordinated expansion of demand could be more successful. Moreover, gender issues should not be neglected in terms of favoring women's employment and entrepreneurship.     

CHILD CARE PRICES AND MATERNAL EMPLOYMENT: A META‐ANALYSIS

The literature estimates for labor force participation elasticity with regard to child care prices are extensive and varying. While some estimates imply substantial gains from child care subsidies, others find insignificant effects. To determine the causes of the variance, this paper reviews and analyzes the elasticity sizes using estimates from 36 peer‐reviewed articles and working papers in the literature. We start by reviewing the theoretical and empirical aspects related to participation elasticity with regard to child care costs, paying special attention to sample characteristics, methodological aspects, and macro level factors. We conclude by providing a meta‐regression using control variables based on our review of the literature to explain some of the differences between the estimates. As research builds on and improves the methods and assumptions in prior works, elasticity estimates have become smaller over time. This decline might also be partially explained by changes in labor market characteristics. In countries with high rates of part‐time work and very high or very low rates of female labor force participation, we find elasticity rates to be smaller.     

论道德效力及其表征

道德效力不仅仅是道德规范的影响力,而是道德价值体系整体的效力,是道德价值体系本身所具有的能实现一定社会目标、达到某种社会效果的力量。它不仅是一个量的概念,因受各种因素的影响而在程度上有所不同,而且在性质上也有善与恶的区分。相对于法律效力,道德效力有其独有的特性。其外在表征主要体现在求善的执着、个体的自律和他律、社会秩序的良好三个方面。
