This study examines the cyclical behaviors of firm-level volatility, measured by real sales growth. Japanese firm-level data show that their volatility is countercyclical, whereas it is procyclical among the United States firms reported in a previous study. We formulate a theoretical model that...

In this paper, I present a model in which firm-level uncertainty raises aggregate productivity growth. The mechanism for this is learning-by-doing in the research sector: firms undertake research to reduce uncertainty, which results in social knowledge accumulation that improves the productivity...

This paper constructs a model of technology adoption and diffusion under firm-level uncertainty and then demonstrates that greater firm-level uncertainty may give birth to faster diffusion of a new technology.
