中国的所有制结构与区域劳动生产率收敛

基于2001~2017年中国工业分企业所有制-分地区-分行业的面板数据，利用相对劳动生产率和变异系数指标对全国和分区域的国有企业、私营企业、外商和港澳台企业的劳动生产率增长和收敛性进行描述性分析，并运用双向固定效应模型对其进行计量检验。结果显示：从全国范围来看，三类所有制结构的劳动生产率均呈现显著的绝对收敛和条件收敛，但是收敛速度呈现差异。其中，私营企业收敛速度最快，外商和港澳台企业次之，国有企业收敛速度最慢。分区域来看，东北和西部收敛速度相对较快，中部次之，而沿海三类所有制结构的劳动生产率收敛速度均较慢。因此，政府应进一步从深化国有企业改革、鼓励非公有制经济发展和完善市场竞争等方面努力，有助于缩小区域发展差距和促进所有制结构的收敛，从而带动整体经济的收敛。     

The interaction effect of gender and ethnicity in loan approval: A Bayesian estimation with data from a laboratory field experiment

Microfinance targets women and uses loan provision as a tool for empowerment, which translates into better household nutrition, improved education, and a scale down of domestic violence. However, ethnic discrimination in microfinance may exist in countries with a segregated indigenous population. We assessed this possibility with a field experiment in Bolivia. The controlled laboratory experiment evaluated whether credit officers rejected microloan applications based on the interaction effect of ethnicity and gender of potential borrowers. Point estimates of a Bayesian mixed‐effects logistic regression, estimated with the experimental data, indicate that nonindigenous women have double the chance of loan approval, but indigenous women have only 1.5 times the chance of loan approval when compared with men. While the findings about gender are limited, the evidence for the interaction of gender and ethnicity is more robust and suggests the existence of positive taste‐based discrimination favorable for nonethnic women in Bolivia. We conclude that the affirmative actions towards women promoted by development agencies and microfinance institutions must not overlook ethnicity as an important factor for financial policies of sustainable development. In practice, these policies should be aimed at identifying and reducing both social desirability bias and the structural barriers to financial inclusion that indigenous women may face when trying to obtain access to a loan.     

How do female directors improve board governance? A mechanism based on norm changes

Prior literature documents that corporate boards with female directors produce better governance outcomes than all-male boards. However, female directors constitute the minority on most boards, which precludes majority voting as the mechanism through which they change board decisions. We identify changing the norms of how the board works as this mechanism. Using the market for norms framework, we explain how female directors are effective even without possessing a board majority or other sources of symbolic power, such as hierarchical authority and social gravitas. Empirically, we show that independent female directors, compared to their male counterparts, are more effective at changing board norms (board processes) and improving governance (board outputs).     

Work,Care and Gender during the COVID-19 Crisis*

We explore the effects of the COVID-19 crisis and the associated restrictions to economic activity on paid and unpaid work for men and women in the United Kingdom. Using data from the COVID-19 supplement of Understanding Society, we find evidence that labour market outcomes of men and women were roughly equally affected at the extensive margin, as measured by the incidence of job loss or furloughing. But, if anything, women suffered smaller losses at the intensive margin, experiencing slightly smaller changes in hours and earnings. Within the household, women provided on average a larger share of increased childcare needs, but in an important share of households fathers became the primary childcare providers. These distributional consequences of the pandemic may be important to understand its inequality legacy over the longer term.

German stagnation versus Swedish progression: gender wage gaps in comparison, 1960–2006

This article provides a comparative analysis of the development of the gender wage gap in West Germany and Sweden during the period 1960–2006. Despite the economic similarities including broad social safety nets, the gap has developed differently since 1960. This analysis accounts for micro- and macroeconomic factors and politics and concludes that norms and traditions penetrate institutional settings and ensnare Germany in a cultural trap with regard to gender equality. While Sweden has moved to a two-earner model, German society expects mothers to stay at home. The micro analysis shows that family concerns (e.g. marriage and motherhood) decrease female income in Germany to a far greater extent than do such factors in Sweden, which can be explained in part by deeply held social attitudes.     

Microfinance and gender inequality: cross-country evidence

Microfinance enables poor women to engage in income-generating activities, which helps them become financially independent, strengthening their decision-making power within the household and society. Consequently, microfinance has the potential to reduce gender inequality (GI). Case-study evidence from across the developing world both supports and contradicts this hypothesis. We therefore revisit this issue using macroeconomic cross-country panel data for 64 developing economies over the period 2003–2014. We find that women’s participation in microfinance is associated with a reduction in GI. However, regional interactions reveal that cultural factors are likely to influence the GI–microfinance nexus.     

A Gendered Model of the Peasant Household: Time poverty and Farm Production in Rural Mozambique

Using insights from a case study on the allocation of labor in subsistence households in Mozambique, this study develops a conceptual framework for examining linkages between time poverty and farm production. An unexpected event such as a health crisis increases the demand for labor provided by women, thus making them more time poor. The model and numerical simulations show that a deterioration in a woman's time constraint will have an adverse effect on agricultural output of the household. This occurs because most women respond to an increase in household work by reducing their work hours on the farm and by reducing their leisure time. The latter outcome is expected to have a negative effect on women's physical and mental health, which will then cause a decline in their productivity on the farm.     

Intergenerational Correlations of Extreme Right‐Wing Party Preferences and Attitudes toward Immigration

In this paper, we analyze the importance of parental socialization on the development of children's far right‐wing preferences and attitudes toward immigration. Using longitudinal data from Germany, our intergenerational estimates suggest that the strongest and most important predictor for young people's right‐wing extremism are their parents' right‐wing extremist attitudes. While intergenerational associations in attitudes toward immigration are equally high for sons and daughters, we find a positive intergenerational transmission of right‐wing extremist party affinity for sons, but not for daughters. Compared to the intergenerational correlation of other party affinities, the high association between fathers' and sons' right‐wing extremist attitudes is particularly striking.
