This paper analyzes the process of Internet diffusion across the world using a panel of 199 countries during 1990-2004. The authors group countries in two categories-low and high-income countries-and show that the Internet diffusion process is well characterized by an S-shape curve for both...

The old-age security hypothesis establishes that one important reason why parents have a large offspring is to ensure that they will receive financial support from them in old age. In this paper we use data on fertility and financial development in 19th century U.S. to indirectly test this...

Strong evidence indicates that in most countries cities tend to develop sequentially, with the initially largest cities growing first. This paper presents a model of city growth that rationalizes this pattern. Increasing returns to scale constitute the force that favors agglomeration of...

This paper analyzes the process of Internet diffusion across the world using a panel of 214 countries during the period 1990-2004. Countries are classified as low- or high-income and it is shown that the diffusion process is characterized by a different S-shaped curve in each group. The...

Using two comprehensive datasets on populations of cities and metropolitan areas for a large set of countries, I present three new empirical facts about the evolution of city growth. First, the distribution of cities' growth rates is skewed to the right in most countries and decades. Second,...
