Using Japanese scanner data of transaction prices and sales for more than 1,600 commodity groups from 1988 to 2008, we find a statistically significant negative correlation between the frequency of price changes and the degree of market concentration. We also find that structural factors of a...

This study examines the economic consequences of a horizontal merger between Japanese airlines that took place in 2002, with particular emphasis on quality responses to the airline merger. A structural model allows firms to determine not only prices but also flight frequencies. The obtained...

This paper proposes one measure for the productivity of banks and studies how it affects the sensitivity of a client firm's capital investment with respect to investment opportunity. As a direct measure for the productivity of banks, we employ the risk-adjusted profit of an individual bank,...

This study analyzes the effects of managerial ownership on the risk-taking behavior of Korean and Japanese banks during the relatively regulated period of the late 1990s to the early 2000s. It finds that managerial ownership alone does not affect either the risk or the profit levels of Korean...

We study how relationships between firms and banks evolved between during the Twentieth century in Britain. We document and explain a remarkable transition from single to multiple firm-bank relationships during the last twenty years of the sample period. Larger, global, or transparent companies...

We propose a novel observation-driven finite mixture model for the study of banking data. The model accommodates time-varying component means and covariance matrices, normal and Student's t distributed mixtures, and economic determinants of time-varying parameters. Monte Carlo experiments...

This paper investigates whether the benefits of bank–borrower relationships differ depending on three factors identified in the theoretical literature: verifiability of information, bank size and complexity, and bank competition. We extend the current literature by analyzing how relationship...
