Factors shaping international migration, over the last half century, from and into the countries and territories of Sub-Saharan and North Africa, as well as the economic and some social implications of those movements, are examined. Existing analyses of these issues are critically reviewed, including topics particularly pertinent to the African context and evidence on crosscutting themes studie...

We introduce non-homothetic preferences into an R&D based growth model to study how demand forces hape the impact of inequality on innovation and growth. Inequality affects the incentive to innovate via a price effect and a market size effect. When innovators have a large productivity advantage over traditional producers a higher extent of inequality tends to increase innovators’prices and mark...

Previous research on the determinants of international migration has largely focused on objective factors, such as income. We instead use subjective well-being (SWB) to explain international migration desires, an expressed willingness to migrate. We find that individuals with higher SWB have lower international migration desires. At the individual level, the SWB-migration relationship appears t...

This paper challenges the current belief that income inequality has a negative relationship with economic growth. It uses an improved data set on income inequality which not only reduces measurement error, but also allows estimation via a panel technique. Panel estimation makes it possible to control for time-invariant country-specific effects, therefore eliminating a potential source of omitte...

This paper provides an overview of methodologies used to analyze inter-regional income inequality, and a critical survey of empirical studies that deal with Russian regions. It discusses implications of the growth theory regarding dynamics of inter-economy income inequality. Methodologies for empirically analyzing income inequality are classified as the cross-section approach, time series appro...

This paper develops a mobility measure that combines desirable features of the relative and absolute approaches to measuring mobility. From the relative approach we borrow the idea that income growth accruing to the relatively poor is more to be valued than income growth to the relatively rich. From the absolute approach we take the idea that upward changes are to be valued, in and of themselve...

This paper analyzes the evolution of Chinese urban income distribution across space and time in post-reform era. Our results suggest no evidence on income convergence across cities during the period 1984-2003. We find that cities with comparable income level are likely to be co-located in the same region; further, cities tend to mirror the mobility of their counterparts located in the same prov...

I investigate whether a school-based deworming intervention in Kenya had long-term effects on young children in the region. I exploit positive externalities from the program to estimate impacts on younger children who were not directly treated. Ten years after the intervention, I find large cognitive effects—comparable to between 0.5 and 0.8 years of schooling—for children who were less than on...

Three main changes in thinking about poverty have gained increasing currency over the past decade. First, the concept of poverty has broadened, with increasing attention to issues of vulnerability, inequality and human rights. Second, the causal structure has broadened to include causal variables, such as social, political, cultural, coercive and environmental capital. Third, the causal structu...
