This paper investigates how a firm's borrowing cost evolves as it ages. Using a new data set of more than 200,000 bank-dependent small firms in 1997-2002, we find the following. First, the distribution of borrowing cost tends to become less skewed to the right over time. Second, this shift of...

This paper investigates how firms' borrowing costs evolve as they age. Using a new panel data set of about 100,000 bank-dependent small firms for 1997-2002 and focusing on the channel of "adaptation" (i.e., surviving firms' borrowing costs decline as they age) and that of "selection" (i.e.,...

This paper estimates fiscal policy feedback rules in Japan, the United States, and the United Kingdom for more than a century, allowing for stochastic regime changes. Estimating a Markov-switching model by the Bayesian method, we find the following: First, the Japanese data clearly reject the...

Why are product prices in online markets dispersed in spite of very small search costs? To address this question, we construct a unique dataset from a Japanese price comparison site, which records price quotes offered by e-retailers as well as customers’clicks on products, which occur...

We discuss a mechanism through which inversion symmetry (i.e., invariance of a joint probability density function under the exchange of variables) and Gibrat's law generate power-law distributions with different tail exponents. Using a dataset of firm size variables, that is, tangible fixed...
