摘要：We examine the impact of informal risk sharing on risk taking incentives when transfers are organized through a social network. A bilateral partial sharing rule satisfies that neighbors share equally a part of their revenue. In such a society, correlated technologies generate interdependent risk levels. We obtain three findings. First, there is a unique and interior Nash-equilibrium risk profile, and it is in general differentiated and related to the Bonacich measure of the risk sharing networ...

摘要：The custom often acts as a powerful hindrance to equity-increasing changes. In this paper, we present a simple model of legal dualism in which a progressive legal reform can, under certain conditions, shift the conflicting custom in the direction intended by the legislator. Formal law then acts as an outside anchor that exerts a 'magnet effect' on the custom. We also characterize the conditions under which a moderate reform performs better than a radical one in improving the welfare of the dis...

摘要：We consider the effect of export sophistication on economic performance by appealing to regional variation within one single country (China) over the 1997-2009 period. We find evidence in support of Hausmann, Hwang and Rodrik (2007), in that regions specializing in more sophisticated goods subsequently grow faster. We find substantial variation in export sophistication at the province and prefecture level, controlling for the level of development, and that this sophistication in turn drives gr...

摘要：How do neighbors positively or negatively influence individuals living in rural Malawi to learn their HIV results? Using data of location of homes and distance to neighbors, we measure the social network effects of neighbors' learning their HIV results on individuals own learning. Using the fact that neighbors were randomly offered monetary incentives of varying amounts to learn their HIV results, we find positive effects of neighbors attending clinics on others living nearby: a 10 percentage ...

摘要：This study presents a new measure of financial development that is directly derived from theory. Our measure, the Marginal Utilization of Debt (hereafter, MUD) comes from the seminal work of Myers (1984), Myers and Majluf (1984) and Shyam-Sunder and Myers (1999). Further, it is directly related to the development facts of Gurley and Shaw (1955). MUD is a global measure that reflects conditions in both debt and equity markets. It varies enormously across nations; from 0.23 in Australia at one e...

摘要：This paper examines the effects of learning HIV status on economic behavior among rural Malawians. According to economic life-cycle models, if learning HIV results is informative about additional years of life, being diagnosed HIV-positive or negative should predict changes in consumption, investment and savings behavior with important micro and macro-economic implications. Using an experiment that randomly assigned incentives to learn HIV results, I find that while learning HIV results had sh...

摘要：Using a rich dataset from West Africa. we examine the household characteristics associated with membership in community-based organizations (CBOs). We find that on average it is the more fortunate members of rural society who belong in CBOs. In Senegal, the dominant criterion is land ownership. In Burkina Faso it is age and family ties with village authorities. Ethnicity plays a role as well: CBO membership is less likely for ethnic groups that traditionally emphasize livestock raising. Next w...

摘要：This paper takes a new look at the long-run implications of resource abundance. It develops a Schumpeterian model of endogenous growth that incorporates an upstream resource-intensive sector and yields an analytical solution for the transition path. It then derives conditions under which, as the economy's endowment of a natural resource rises, (i) growth accelerates and welfare rises, (ii) growth decelerates but welfare rises nevertheless, and (iii) growth decelerates and welfare falls. Which ...

摘要：In this paper, we develop a theoretical model of household production, bargaining and credit to analyse how access to microcredit affects intra-household decision-making and welfare, and identify conditions under which female household members are most likely to benefit. We show that, consistent with ethnographic accounts of the impact of microcredit programmes on poor households, access to loans can lead to a variety of outcomes for intra-household decision-making and welfare depending on ini...

摘要：We estimate a remittance model in which we address endogeneity and reverse causality relationships between immigrants' remittances, pre-transfer income and consumption. In order to take into account the fact that a large share of individuals do not remit, instrumental variable variants of the double-hurdle and Heckit selection models are proposed and estimated by Limited Information ML; semiparametric extensions are considered as robustness checks. Our results for a sample of recent immigrants...
