The Japanese government's Abenomics policy has been beneficial mainly for some large companies thus far, and policies that also can spread the benefits to local areas and small and medium-sized enterprises (SMEs) are needed. It is regretful that no such model exists in Japan, thus I conducted a...

We construct a monetary model of financial crises that can explain two characteristic features of the global financial crisis in 2008/2009, namely, the widespread freeze of asset transactions and a sharp contraction in aggregate output. We assume that the assets, such as real estate, work as...

We generalize Lagos and Wright's (2005) framework for a monetary economy in a way that there exist two technologies, "high" and "low," for producing the goods in a decentralized matching market. The high technology is more productive than the low technology, while the agents who use the high...

This paper constructs a model of financial crises that can explain characteristic features of the global financial crisis of 2008-2009, namely, the widespread freezing of asset transactions, the sharp contraction of aggregate output, and a deterioration in the labor wedge. This paper assumes...

We propose a simple model of financial crises, which may be useful for the unified analysis of macro and financial policies implemented during the 2008-2009 financial crisis. A financial crisis is modeled as the disappearance of inside money due to the lemon problem à la Akerlof (1970), in a...

Financial factors and ownership structure are both part of the determinants of corporate R&D investment. Considering listed firms in the R&D intensive industries during the 2000s, this paper examines whether financial factors and ownership structure explain R&D investment in Japan. Following the...

This paper starts out from the observation that the export shares of firms (export to sales ratio) vary greatly among firms, and tend to be systematically related to the firms' capital labour ratios. This observation cannot be explained by e.g. the standard Melitz model, since it predicts that...

This paper investigates the effects of taxation on the distributions of income and wealth and on the welfare of heterogeneous households. I first demonstrate that the tails of income and wealth distributions converge to a Pareto distribution in a Bewley model in which households bear...

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,...

We consider a (pure) public goods provision problem with voluntary participation in a quasi-linear economy. We propose a new hybrid solution concept, the free-riding-proof core (FRP-Core), which endogenously determines a contribution group, public goods provision level, and how to share the...
