Although previous works have discussed the benefits of precolonial centralization for development in Africa, the findings and the mechanisms provided do not explain the heterogeneity in development outcomes of formerly centralized states. Using new survey data from Nigeria, I find a significant negative effect of precolonial centralization on access to certain public services for centralized re...

The present paper thoroughly explores second-best efficient allocations in an adverse selection insurance economy. We start from a natural extension of the classical model, assuming less than perfect risk perceptions. We propose first and second welfare theorems, by means of which we describe efficiencyenhancing policies. Notions of weak and strong adverse selection are promising for interpreti...

OBJECTIVE To evaluate the use of the ML Flow test as an additional, serological, tool for the classification of new leprosy patients. DESIGN In Brazil, Nepal and Nigeria, 2632 leprosy patients were classified by three METHODS : (1) as multibacillary (MB) or paucibacillary (PB) according to the number of skin lesions (WHO classification), (2) by slit skin smear examination, and (3) by serolo...

This simple paper models the production allocation choices of a multinational enterprise (MNE) in a three-country framework -a northern country and two southern countries. The products made in the southern countries are of lower quality, and have higher substitutability than those between the south and the north. We investigate how exchange rates affect production, employment, profits and welfa...

Recent models of international trade have identified product quality as an important determinant of bilateral trade flows. Yet relatively little is understood about the relationship between the characteristics of the export market and the quality of products. In this paper we examine this link using Chinese data. We find evidence that product unit values vary with standard gravity variables in ...

Do international trade and technological change influence how firms create incentives for human capital? I present a model that incorporates agency problems into a framework with firm heterogeneity and human capital. My model indicates that trade liberalizations and skill-biased technological change alter the way how the largest firms in an economy incentivize their managers. Increases in manag...

This paper evaluates the impact of China’s WTO accession on patterns of world trade and economic growth by a recursive dynamic, 17-region, 25-sector computable general equilibrium (CGE) model with import embodied technology transfer based on actual market access commitments that China and Taiwan have made to date. The simulation results show that the major gains from WTO accession would accrue ...

Many industrialized economies have seen a rapid rise in top income inequality and in the globalization of production since the 1980s. In this paper I propose an open economy model of executive pay to study how offshoring affects the pay level and incentives of top earners. The model introduces a simple principal-agent problem into a heterogeneous firm talent assignment model and endogenizes pay...

Communication is a real barrier to organizing international production as it hinders knowledge transmission. This paper provides evidence to suggest that a way in which multinational firms economize on costly information transfers is by using skilled foreign workers, since local talent can substitute for knowledge inputs from the headquarters. Combining U.S. data on headquarter service exports ...
