The Global Repository of Income Dynamics (GRID) is a new open-access, cross- country database that contains a wide range of micro statistics on income inequality, dynamics, and mobility. It has four key characteristics: it is built on micro panel data drawn from administrative records; it fully...

The economic effects of climate change vary across both time and space. To study these effects, this paper builds a global economy-climate model featuring a high degree of geographic resolution. Carbon emissions from the use of energy in production increase the Earth's (average) temperature and...

This paper develops a model that integrates the climate and the global economy---an integrated assessment model---with which different policy scenarios can be analyzed and compared. The model is a dynamic stochastic general-equilibrium setup with a continuum of regions. Thus, it is a full...

This paper builds a theory of the distribution of TFP across countries. The theory is based on the hypothesis that TFP improvements in a given country follow a Nelson-Phelps specification: they derive from past investments in the country itself and, through a spillover term, from past...

We use a new micro data set to estimate a stochastic industry-equilibrium model of the oil industry. This effort is a first step towards studying the importance of ongoing structural changes in the oil market in a general-equilibrium model of the world economy. We analyze the impact of the...

The Global Repository of Income Dynamics (GRID) is a new open-access, cross- country database that contains a wide range of micro statistics on income in- equality, dynamics, and mobility. It has four key characteristics: it is built on micro panel data drawn from administrative records; it...

We construct an integrated assessment model with multiple energy sources—two fossil fuels and green energy—and use it to evaluate ranges of plausible estimates for the climate sensitivity, as well as for the sensitivity of the economy to climate change. Rather than focusing explicitly on...

We use a new micro data set that covers all oil fields in the world to estimate a stochastic industry-equilibrium model of the oil industry with two alternative market structures. In the first, all firms are competitive. In the second, OPEC firms act as a cartel. This effort is a first step...
