This paper analyzes the process of Internet diffusion across the world using a panel of 199 countries during the time interval 1990-2004. We 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...

In this chapter, we review the recent and growing literature on medium-term growth patterns. This strand of research emerged from the realization that for most countries economic development is a highly unstable process; over a few decades, a typical country enjoys periods of rapid growth as...

There is much evidence that less democratic countries experience more high-frequency growth volatility. In this paper we report a similar finding about volatility in the medium term: we find evidence that reversals of trend-growth are sharper and more frequent in non-democracies. Motivated by...

We present a general equilibrium dynamic model that characterizes the gap between optimal and equilibrium fertility and investment in human capital. In the model, the aggregate production function exhibits increasing returns to population arising from specialization but households face the...

This paper aims to study the effect of a major historical event on the Spanish city size distribution, the Spanish Reconquista. This was a long military campaign that aimed to expel Muslims from the Iberian Peninsula. The process started in the early 1200s and ended around 1500, when the entire...

In this paper we develop a dynamic model that explains the pattern of population and production allocation in an economy with an urban location and a rural one. Agglomeration economies make urban dwellers benefit from a larger population living in the city and urban firms become more productive...

This paper studies the effect of the Spanish Reconquest, a military campaign that aimed to expel the Muslims from the Iberian Peninsula, on the population of its most important cities. The almost four centuries of Reconquest offer a “quasi-natural” experiment to study the persistence of...

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...
