Ricardian theories of production often take the comparative advantage of locations in diff erent industries to be uncorrelated. They are seen as the outcome of the realization of a random extreme value distribution. These theories do not take a stance regarding the counterfactual or implied...

In this paper we document that the probability that a product is added to a country’s export basket is, on average, 65% larger if a neighboring country is a successful exporter of that same product. We interpret our result as evidence of international intra-industry knowledge diffusion. Our...

Countries differ markedly in the diversification of their exports. Products differ in the number of countries that export them, which we define as their ubiquity. We document a new stylized fact in the global pattern of exports: there is a systematic relationship between the diversification of a...

Urban change involves transformations in the physical appearance and the social composition of neighborhoods. Yet, the relationship between the physical and social components of urban change is not well understood due to the lack of comprehensive measures of neighborhood appearance. Here, we...

In this paper we examine several dimensions of gender disparity for a sample of 40 countries using micro-level data. We start by documenting the reversal of the gender education gap and ranking countries by the year in which it reversed. Then we turn to an analysis of the state of other gaps...

Much of development policy has been based on the search for a short to do list that would get countries moving. In this paper I argue that economic activity requires a large and highly interacting set of public policies and services, which constitute inputs into the production process. This is...

The main purpose of industrial policy is to speed up the process of structural change towards higher productivity activities. This paper builds on our earlier writings to present an overall design for the conduct of industrial policy in a low- to middle-income country. It is stimulated by the...

As part of the Accelerated and Shared Growth Initiative (ASGISA), the National Treasury of the Republic of South Africa convened an international panel of economists through Harvard's Center for International Development. This panel spent two years analyzing the South African economy and its...

We revisit the well-known fact that richer countries tend to produce a larger variety of goods and analyze economic development through (export) diversifcation. We show that countries are more likely to enter ‘nearby’ industries, i.e., industries that require fewer new occupations. To...

We study the factors behind the public sector premium in Albania and Sri Lanka, the group heterogeneity in the premium, the sources of public sector wage compression, and the impact of this compression on the way individuals self-select between the public and the private sector. Similar to other...
