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...

Money is not neutral if firm entry and exit are incorporated into a menu cost model. The real effect of money increases as a firm entry and exit rate increases, and the key is non-uniform firm distribution.

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.

In this paper, I investigate the effect of substitutability among final goods on welfare growth under the environment that productivity growth in each industry is not independent of one another. In such an environment, less substitutability is favorable to the welfare growth rate and the steady...

In this study, we analyze the relationship between inflation and economic growth. To this end, we construct a model of endogenous growth with creative destruction, incorporating sticky prices due to menu costs. Inflation and deflation reduce the reward for innovation via menu cost payments and,...

In this paper, we analyze the relationships among oil prices, clean energy stock prices, and technology stock prices, endogenously controlling for structural changes in the market. To this end, we apply Markov-switching vector autoregressive models to the economic system consisting of oil...

The Luenberger productivity index can simultaneously contract inputs and expand outputs, and is dual to profit maximization. The index is a generalization of the Malmquist productivity index, which is commonly used in productivity studies. Both the Luenberger and Malmquist productivity indices...
