Journal Article
The Great Kanto Earthquake occurred on 1 September 1923 and inflicted serious damage on Yokohama City. About 90 percent of the factories in Yokohama City were burnt down or completely destroyed. However, these manufacturing industries appear to have swiftly recovered in the aftermath of the damage. This article investigates the role of creative destruction due to the Great Kanto Earthquake. Using firm-level data on capital (horsepower of motors) before and after the earthquake, we find substantial creative destruction, that is, upgrade of machine technology and/or survival of efficient firms. We find further collaborating evidence of this at the prefecture level.

Toshihiro OkuboThis paper studies tax competition in an economic geography model that allows for agglomeration economies with trade costs and heterogeneous firms. We find that the Nash equilibrium involves a large country charging a higher tax than a small nation. Lower trade costs lead to an intensification of competition, a drop in Nash tax rates and a narrowing of the gap. Since large, productive firms are naturally more sensitive to tax differences in our model, large firms are the crux of tax competition in our model. This also means that tax competition has consequences for the average productivity of big and small nations' industries; by lowering tax rates, a small nation can attract high-productivity firms.
