The class of growth models that incorporate nonrivalry and/or externalities implies that the size (scale) of an economy influences its growth rate. Ample empirical evidence exists to suggest that such implied scale effects are counter-factual. The objective of this paper is to develop a general...

More than thirty years ago Milton Friedman proposed a 'plucking' model of business fluctuations in which output cannot exceed a ceiling level, but will, from time to time, be plucked downward by recession. The model implied that business fluctuations are asymmetric, that recessions have only a...

We propose a coherent unified approach to the study of the linkages among economic growth, financial structure, and inequality, bringing together disparate theoretical and empirical literature. That is, we show how to conduct model-based quantitative research on transitional paths. With...

The First Millennium Development Goal (MDG#1) is to cut the fraction of global population living on less than one dollar per day in half, by 2015. Foreign aid financed investments may contribute to the attainment of this goal. But how much can aid be reasonably expected to accomplish? A...

This paper studies the changes in world business cycles during 1960-2003. We employ a Bayesian dynamic latent factor model to estimate common and country-specific components in the main macroeconomic aggregates of the Group of Seven (G-7) countries. We then quantify the relative importance of...

Financial liberalization has been a controversial issue as there is little empirical evidence for its positive effects on economic growth. However, we find sizable welfare gains, 1 to 28 percent of permanent consumption though, consistent with the literature, the gain in the economic growth is...

This paper compares the pattern of macroeconomic volatility in 17 Latin American countries during episodes of high and low growth since 1970, examining in particular the role of policy volatility. Macroeconomic outcomes are distinguished from macroeconomic policies, structural reforms and...

This paper analyzes the dynamic interactions between the precision of information, technological development, and welfare within an overlapping generations model. More precise information about idiosyncratic production shocks has ambiguous effects on technological progress and welfare, which...
