In this paper we compare sources of economic growth in Japan and the United States from 1975 through 2003, focusing on the role of information technology (IT). We have adjusted Japanese data to conform to U.S. definitions in order to provide a rigorous comparison between the two economies. The...

The distribution of the population of cities has attracted a great deal of attention, in part because it sharply constrains models of local growth. However, to this day, there is no consensus on the distribution below the very upper tail, because available data need to rely on the "legal" rather...

Are smarter machines our children's friends? Or can they bring about a transfer from our relatively unskilled children to ourselves that leaves our children and, indeed, all our descendants - worse off? This, indeed, is the dire message of the model presented here in which smart machines...

The main aim of this paper is to assess the validity of the life cycle model of consumption. In particular, we address an issue that has recently received much attention, especially in the macroeconomic literature: that of "excess sensitivity" of consumption growth to income growth. We do this...

In this paper we show that some of the predictions of models of consumer intertemporal optimization are not inconsistent with the patterns of non-durable expenditure observed in US household-level data. Our results and our approach are new in several respects. First, we use the only US micro...

We use an extended Barro-Becker model of endogenous fertility, in which parents are heterogeneous in their labor productivity, to study the efficient degree of consumption inequality in the long run. In our environment a utilitarian planner allows for consumption inequality even when labor...

Liquidity constraints and, more generally, imperfections in credit markets, can be extremely important for the intertemporal allocation of consumption and have received a substantial amount of attention in the theoretical and empirical literature on consumption. In the first part of the paper I...

Many studies of regional disparity in China have focused on the preferential policies received by the coastal provinces. We decomposed the location dummies in provincial growth regressions to obtain estimates of the effects of geography and policy on provincial growth rates in 1996-99. Their...

This paper examines how preference heterogeneity affects the ability of the poor to extract resources from the rich. We study the equilibrium of a game in which coalitions of individuals form parties, parties propose platforms, and all individuals vote, with the winning policy chosen by...
