Modeling Bank Runs in Financial Crises

In recent years, financial crises have occurred frequently in each region, and banks are facing harsh management environments. Bank runs of customers during a financial crisis are one of a bank’s most serious risks. This research aims to build a bank run model for financial crises, use that model to estimate the amount of deposit funds which flow out, and propose a framework for financial crisis risk management. The model proposed in this paper enables understanding of the factors which have the largest impacts on bank runs, providing valuable information for banks to cope with such risks. The model uses survey data, and clarified that bank runs have differences which depend on customer characteristics and branch location. We understood that during a financial crisis, an appropriate branch strategy must be adopted depending on the location and customer characteristics of each bank branch.     

Consumption taxation, social status and indeterminacy in models of endogenous growth with elastic labor supply

In this paper, we examine the effects of consumption taxation on long-run growth in an infinitely lived representative-agent model of endogenous growth with endogenous labor supply in which the desire for social status induces private agents to care about others’ wealth or consumption levels. This analysis shows that the increase in consumption taxation raises (reduces) the long-run growth rate when the equilibrium path is locally indeterminate (determinate), provided the desire for social status is not too strong in the relative wealth model. By contrast, in the consumption externalities model, the same result holds, if the Frisch labor supply and labor demand curves have the ‘normal’ slopes at their intersection point, while the result is reversed if these two curves have the ‘wrong’ slopes.     

WHAT ACCOUNTS FOR JAPAN'S HIGH RATE OF GROWTH?*

The purpose of this paper is to investigate the sources of economic growth in Japan and to compare the results with those in the U.S. and Europe as studied by E. F. Denison. The method used by Denison is followed as far as possible. The character of this paper is of fact finding, and the interpretation of results or the originality of methodology is not dealt with here. The results may be summarized as follows. (1) Japan's growth rate is two times that of Europe and three times that of the United States. (2) The contributions of labor, capital, and the residual to economic growth are all higher for Japan than for the U.S. or Europe. (3) Factors which account for the higher contribution of labor to economic growth are (a) the higher rate of increase in employment, (b) less shortening of working hours, and (c) improved age and sex composition. (4) Factors which account for the higher contribution of capital to economic growth are a higher rate of increase in capital input and the high elasticity of production with respect to capital. (5) Other notable points include: (a) the contribution of education is lower for Japan; (b) the capital-labor ratio in Japan increased remarkably; (c) capital's share of national income is higher; and (d) 60% of Japan's economic growth is accounted for by the residual.
