摘要：Social tensions impede social cohesion and public goods provision, and can be a driving force for more serious conflicts such as civil wars. Surprisingly, the emergence of social tensions has been studied only rarely in the literature. In the present contribution a game-theoretic model highlights how reputation concerns and the structure of group cleavages matter for the emergence of social tensions. In particular, the respective effects of ethnic fractionalization, polarization and segregatio...

摘要：Skilled emigration (or brain drain) from developing to developed countries is becoming the dominant pattern of international migration today. Such migration is likely to affect the world distribution of income both directly, through the mobility of people, and indirectly, as the prospect of migration affects the rate of return to education in both the sending and receiving economies. This migration pattern will therefore affect human capital accumulation and fertility decisions in both the sen...

摘要：In this paper, Bayesian methods and the Finnish aggregate infrastructure capital series from 1860 to 2003 are used to explore how government infrastructure policy affects long-run output growth. We use Finnish data, since to the best of our knowledge the Finnish land and water construction investments series is the best available sufficiently long time series on aggregate infrastructure investments. The Finnish data provide strong and robust evidence indicating that permanent changes in govern...

摘要：Conditional cash transfer programs seek to break the intergenerational transmission of poverty by building the human capital of poor children. Despite their popularity throughout the developing world, relatively little is known about their effect on children's health outcomes. This paper evaluates the impact of the Mexican conditional cash transfer program, Progresa, on two important health outcomes: infant and neonatal mortality. It exploits the phasing-in of Progresa over time throughout rur...

摘要：This paper investigates the welfare effects of brain-drain taxes levied by non-benevolent governments, whereby a country collects a tax from skilled emigrants but potentially wastes a sizable portion of the revenue. Using a model in which taxes are chosen to maximize expected political rents. I show that the availability of a brain-drain tax increases a weighted sum of citizen utilities. However, the government's optimal brain-drain tax is found to be higher than the level that maximizes this ...

摘要：The impact of political competition on ethnic discrimination remains largely unexplored. To address this gap, this paper explores the relationship between the level of political competition and the probability of receiving government transfers among ethnic minorities in Sri Lanka in the run up to the national elections of 2000. The paper shows that making politicians dependent on the votes of members of ethnic groups other their own can encourage moderation in discriminatory practices towards ...

摘要：I present a theory of development in which heterogeneously talented entrepreneurs require credit to start new projects and open new sectors. During development the variety of sectors expands, which allows better sorting of entrepreneurial talent. The paper shows that, in addition to increasing the average productivity of matches between agents and sectors, this process also mitigates informational frictions in the financial markets. Furthermore, the impact of sectoral variety on the operation ...

摘要：In early 1994, Kagera - a region in northwestern Tanzania - was flooded by more than 500,000 refugees fleeing from the genocides of Burundi and Rwanda. I use this population shock and a series of topographic barriers that resulted in variation in refugee intensity to investigate the short- and long-run causal effects of hosting refugees on outcomes of local children. This strategy provides evidence of adverse impacts over one year after the shock: a worsening of children's anthropometrics (0.3...

摘要：The role of agriculture in development remains much debated. This paper takes an empirical perspective and focuses on poverty, as opposed to growth alone. The contribution of a sector to poverty reduction is shown to depend on its own growth performance, its indirect impact on growth in other sectors, the extent to which poor people participate in the sector, and the size of the sector in the overall economy. Bringing together these different effects using cross-country econometric evidence in...

摘要：Building on recent advances in the literature and using a rich data set for two cohorts of children aged between one and twelve for Andhra Pradesh, India, we investigate the determinants of children's cognitive as well as non-cognitive skills. We find evidence of self-productivity for cognitive skills and cross-productivity effects from cognitive on non-cognitive skills. Moreover, we demonstrate that parental investment has contemporaneously positive effects on skill levels for all age groups....
