Modelling the impact of women’s education on fertility in Malawi

Many studies have suggested that there is an inverse relationship between education and number of children among women from sub-Saharan Africa countries, including Malawi. However, a crucial limitation of these analyses is that they do not control for the potential endogeneity of education. The aim of our study is to estimate the role of women’s education on their number of children in Malawi, accounting for the possible presence of endogeneity and for nonlinear effects of continuous observed confounders. Our analysis is based on micro data from the 2010 Malawi Demographic Health Survey, and uses a flexible instrumental variable regression approach. The results suggest that the relationship of interest is affected by endogeneity and exhibits an inverted U-shape among women living in rural areas of Malawi, whereas it exhibits an inverse (nonlinear) relationship for women living in urban areas

Should low-wage workers care about where they work? : Assessing the impact of employer characteristics on low-wage mobility

This paper studies the importance of employer-specific determinants in escaping low earnings in Germany. To address the initial conditions problem and the endogeneity of employer retention, we model (intra-firm) low-pay transitions using a multivariate Probit model that accounts for selection into low-wage employment and non-random employer drop-out. Using data from the LIAB Linked Employer–Employee panel, our results indicate that for male workers from the service sector the probability of escaping low-pay increases with employer size. This contrasts with female workers from the service sector, who rather benefit from collective bargaining coverage and local works councils. These findings are consistent with internal labour markets being an important ingredient of male within-firm wage growth, whereas the removal of asymmetric information appears to be more relevant in explaining female workers’ wage transitions

The Benefits and Costs of Renminbi Internationalization

Despite the increasing recognition that the renminbi (RMB) may eventually become a key global currency, several important questions remain to be answered. This paper analyzes the benefits and costs of the RMB becoming an international currency. The benefits include reduced exchange risk, promotion of the development of the financial market, and expansion of firms in the People's Republic of China. The costs include general costs, which complicate monetary policy and exchange rate policy, and several transitional risks. We argue that the benefits of RMB internationalization should surpass its costs, particularly in the long run, and provide comprehensive policy choices for a sustainable process of RMB internationalization
