We study cross-country differences in the aggregate production function whenskilled and unskilled labor are imperfect substitutes. We find that there is a skill biasin cross-country technology differences. Higher-income countries use skilled labormore efficiently than lower-income countries,...

Why are some countries so much richer than others? Development Accounting is a first-passattempt at organizing the answer around two proximate determinants: factors of productionand efficiency. It answers the question “how much of the cross-country income variance canbe attributed to...

We revisitWestern Europe’s record with labor-productivity convergence and tentativelyextrapolate its implications for the future path of Eastern Europe. Thepoorer Western European countries caught up with the richer ones through bothhigher rates of physical capital accumulation and greater...

We present a simple theory of the quality (competence and honesty) of elected officials. Our theoryoffers three main insights. Low-quality citizens have a ‘comparative advantage’ in pursuing electiveoffice, because their market wages are lower than those of high-quality citizens...

We look at disaggregated imports of various types of equipment to make inferences oncross-country differences in the composition of equipment investment. We make threecontributions. First, we document strikingly large differences in investment composition.Second, we explain the differences as...

In this paper we apply the same framework totime-series data from the United States over theperiod 1963–1992. We find that throughout thisperiod the efficiencies of skilled labor and capitalhave risen. The efficiency of unskilled laborhas risen in tandem with those of the otherfactors in the...

We present a joint study of the U.S. structural transformation (thedecline of agriculture as the dominating sector) and regional convergence(of southern to northern average wages).We find empiricallythat most of the regional convergence is attributable to the structuraltransformation: the...

We use data on imports of computer equipment for a large sample of countries between 1970and 1990 to investigate the determinants of computer-technology adoption. We find strongevidence that computer adoption is associated with higher levels of human capital and withmanufacturing trade openness...

This paper introduces various sources of consumer heterogeneity in one-sector representative consumer (RC) growth models and develops tools to study the evolution of the distribution of consumptions, assets and incomes.[...]

This paper studies public-debt runs under alternative assumptions on the distribution oftaxes among tax bases, the distribution of debt among classes of taxpayers, and thedistributive preferences of the government. Asymmetries in the distribution of taxes--arising, for example, from income-tax...
