Why are the old politically successful? We build a simple interest group model in which political pressure is time-intensive, showing that in the political competitive equilibrium each group lobbies for government policies that lower their own value of time but that the old do so to a greater...

We argue that a sensible measure of the aggregate value of human capital is the ratio of total labour income per capita to the wage of a person with zero years of schooling. The reason is that total labour income not only incorporates human capital, but also physical capital: given human...

Some natural resources--oil and minerals in particular--exert a negative and non-linear impact on growth via their deleterious impact on institutional quality. We show this result to be very robust. The Nigerian experience provides telling confirmation of this aspect of natural resources. Waste...

In this paper we try to understand whether national accounts GDP per capita or survey mean income or consumption better proxy for true income per capita. We propose a data-driven method to assess the relative quality of GDP per capita versus survey means by comparing the evolution of each series...

Understanding the complex relations between trade integration and poverty reduction is now a priority for Latin American policymakers. The chapters of this book, penned by eminent authors with a long-standing record in the field, represent the current state of knowledge about trade and poverty...

A paper commissioned by the IDB sees trade openness to generate economic growth and help reduce poverty. The study, written by aColumbia University economics professor Xavier Sala-i-Martin, takes a close look at the impact of regional trade agreements, finding benefits to outweigh the potential...

This paper analyzes the role of social safety nets in the form of redistributional transfers and wage subsidies. It argues that public welfare programs can be viewed as devices to prevent crime or disruption because they tend to increase the opportunity cost of engaging in crime or disruptive...

The conventional wisdom that Africa is not reducing poverty is wrong. Using the methodology of Pinkovskiy and Sala-i-Martin (2009), we estimate income distributions, poverty rates, and inequality and welfare indices for African countries for the period 1970-2006. We show that: (1) African...

We use a parametric method to estimate the income distribution for 191 countries between 1970 and 2006. We estimate the World Distribution of Income and estimate poverty rates, poverty counts and various measures of income inequality and welfare. Using the official $1/day line, we estimate that...
