This paper suggests a simulation model to investigate how science and technology fuel economic growth. This model is built upon a synthesis of technological capabilities represented by national innovation systems. This paper gathers data of papers and patents for 183 countries between 1999 and...

Economic prosperity is tied to scientific development, i.e., there is a strong correlation between science, technology and the wealth of nations. We collected data from scientific and technological production of 183 countries of the last thirty years (1974 to 2003) and applied a...

Central concepts of contemporary life-politics, civilization, and citizenship-derive from city form and organization. The city expresses the socio-spatial division of labor and Henri Lefebvre proposes to think of its transformation on the bases of a continuum that extends from the political city...

The regional development in China in the period 1949-2000 has two stages. In the first one (1949-1978), the aim was to control the territory. During three decades the government encouraged the convergences of per capita income among regions, rural, and urban areas, the industry was...

We consider infinite horizon economies with incomplete financial markets. Securities are in positive net supply and may be infinite-lived. We establish existence of equilibria by requiring borrowing constrains instead of portfolio restrictions..

We propose a new regression method to estimate the impact of explanatory variables on quantiles of the unconditional distribution of an outcome variable. The proposed method consists of running a regression of the (recentered) influence function (RIF) of the unconditional quantile on the...

Over the last 15 years, several Latin American cities have adopted dry laws, which restrain the sale of alcohol in bars and restaurants during specific hours of the week. Bogotá, in 1991, was the first. Several more have followed suit, or are likely to do so in the near future. Policy makers...

We develop a general equilibrium model of wealth transfers in the presence of uncertain lifetimes and default. Without introducing exogenous debt constraints, agents are allowed to make collateral-backed promises at any state of their life span.

This paper aims to estimate the effects of maternity leave legislation in women’s wages and employment in Brazil. We analyze the impact of an increase in the leave period, which was raised from 12 weeks to 120 days, as prescribed by the Federal Constitution of 1998. According to the...

While most economic studies of crime have focused on its determinants, we study the reverse question: does crime affect economic behavior? Being such an important social phenomenon, one would expect crime to affect economic decisions. Using local data on crime rates and savings per capita in a...
