In an influential paper Mankiw, Romer, and Weil (1992) argue that the evidence on the international disparity in per-capita income levels and growth rates is consistent with a standard Solow model, once it has been augmented to include human capital as an accumulable factor. In a study on...

In an influential paper Mankiw, Romer, and Weil (1992) argue that the evidence on the international disparity in levels of per capita income and rates of growth is consistent with a standard Solow model, once it has been augmented to include human capital as an accumulable factor. In a study on...

The most important event in human economic history before the Industrial Revolution was the Neolithic transition from a nomadic hunter-gatherer lifestyle to sedentary agriculture, beginning about 10,000 years ago. The transition made possible the human population explosion, the rise of...

Productivity dispersion across firms is large and persistent, and worker reallocation among firms is an important source of productivity growth. The purpose of the paper is to estimate the structure of an equilibrium model of growth through innovation that explains these facts. The model is a...

This chapter examines how international flows of technological knowledge affect economic performance across industries and firms across different countries. Motivated by the large share of the world's technology investments made by firms that are active across country borders, we focus on...

We develop and estimate the steady-state growth equation of an augmented version of Romer's model of endogenous technical change that allows for population growth, human capital accumulation, diminishing returns to R&D, and technology diffusion. Estimates from international cross-section data...
