Business cycle fluctuations in developed economies (N) tend to have large and persistent effects on developing countries (S). We study the transmission of business cycle fluctuations for developed to developing economies with a two-country asymmetric DSGE model with two features: (i) endogenous...

This review article tries to answer four questions: (i) what are the stylized facts about uncertainty over time; (ii) why does uncertainty vary; (iii) do fluctuations in uncertainty matter; and (iv) did higher uncertainty worsen the Great Recession of 2007-2009? On the first question both macro...

We develop a model in which innovations in an economy's growth potential are an important driving force of the business cycle. The framework shares the emphasis of the recent new shock literature on revisions of beliefs about the future as a source of fluctuations, but differs by tying these...

Most countries in the world are not at the technological frontier, yet their economies grow and fluctuate. This paper sets up a quantitative model of endogenous growth with business cycle fluctuations to analyze the medium frequency fluctuations in non-frontier countries. The growth mechanism is...

Difficulties in sorting out the empirical relationship between technical change and employment is attributable, at least in part, to the shortcomings associated with traditional measures of the former. In this paper, we use new indicators of technical change that we believe resolve many issues...

We present new indicators of U.S. technological change for the period 1909-49 based on information in the Library of Congress’ catalogue. We use these indicators to estimate the connections between technological change and economic activity, and to investigate the relationship between...
