Evidence from historical and epidemiological literatures show that epidemics tend to spread in the population according to a logistic pattern. We conjecture that the impact of new technologies on output follows a pattern of spread not unlike that of typical epidemics. After reaching a critical...

This paper extends Grossman and Helpman’s seminal work (1991), and presents an endogenous growth model where innovations created in a high-tech sector may be assimilated or adapted by a low-tech sector. Applying a simple Heckscher-Ohlin framework, the effects of technological diffusion are...

With efforts across the industrial countries to increase the amount of foreign aid mounting, it is important to understand its determinants. This paper examines the factors affecting the support for foreign aid among voters in donor countries. A simple theoretical model, which considers an...

We estimate the effect of training quality on earnings using a Peruvian program, which targets disadvantaged youths. The identification of causal effects is possible because of two attractive features in the data. First, selection of training courses is based on public bidding processes that...

A key question in development economics is whether nutritional deficiencies generate intergenerational poverty traps by reducing the earnings potential of children born into poverty. To assess the causal influence on human capital of one of the most widespread micronutrient deficiencies,...

This paper fills a void in the issue of determinants of privatization prices by concentrating in one industry across many countries. This has not been done before, as the literature has only focused on (i) many industries in one country, (ii) a single industry in one country, and (iii) many...

This paper explores the link between compulsory voting and income distribution using a cross-section of countries around the world. Our empirical cross-country analysis for 91 countries during the period 1960-2000 shows that compulsory voting, when enforced strictly, improves income...

Since efforts by industrial countries to increase the amount of foreign aid they provide have been on the rise recently, it is important to understand the determinants involved. This paper examines the factors affecting support for foreign aid among voters in donor countries. The theoretical...

Critics of privatization argue that poor labor force restructuring is a key concern and that governments should establish better retrenchment programs. Using new data from a random sample of 400 companies in the world, we test competing theories about the wisdom of retrenchment programs and...
