ON THE SUSTAINABILITY OF GOVERNMENT BORROWING IN A DYNAMIC GENERAL EQUILIBRIUM

Abstract.  This paper constructs a dynamic general equilibrium model with money in consumers' utility functions and investigates the equilibrium dynamics of government's debt. The limitation level of the government borrowing for which a dynamic equilibrium and the no Ponzi Game condition are compatible with each other is explicitly derived. The critical level depends on the long-run interest rate, primary balance, money supply etc.     

The role of primary processing in the supply risks of critical metals

This study seeks to understand the role of primary processing, i.e. the first post-mining stage, in supply risk, by means of a case study on three critical metals (neodymium, cobalt, and platinum) in the context of Japan. Applying the ‘footprint’ concept with a multiregional input–output model, we have quantified the direct and indirect vulnerability of the Japanese economy to such risks. Considering the supply risks associated with primary processors, we find that Japanese final consumers are exposed to relatively higher supply risks for neodymium as compared with cobalt and platinum. Our study shows that the primary processing stage of a metal’s supply chain may contribute significantly to the overall supply risks, suggesting that this stage should be taken into due account in understanding and mitigating supply-chain vulnerability through, e.g. supplier diversification and alternative material development.     

Why Do Japanese Non-Local Regional Banks Enter Other Prefectures Under the Region-Based Relationship Banking Policy?

In this study, we investigate the market characteristics of prefectures in which non-local regional banks of other prefectures choose to enter and their motivations for doing so, considering the Japanese government’s requirements for regional financial institutions to actively stimulate their local economies. In particular, by pooling prefecture-level data, the market characteristics of prefectures that experience more entrances by non-local regional banks compared with other prefectures are examined. It was found that entrance by non-local regional banks is more common in prefectures containing active high-performing companies. Hence, it can be considered that non-local regional banks that are not satisfied with lending opportunities in their home prefectures enter other prefectures to increase their lending opportunities to high-performing companies. This study contributes to the clarification of why many regional banks do not concentrate on businesses within their local regions and intentionally enter other prefectures, which is in contrast with the intent of the region-based relationship banking policy.     

Retail corporate groups: Challenges of omnichannel management in Japan

Abstract

The omnichannel varies across countries due to different retail environments and retailers’ growth strategies. The Japanese big retailers’ omnichannel can be characterized by having multiple retail formats, such as department stores, general merchandise stores, convenience stores, specialty stores, Internet stores, and so on. They have grown by multiplying retail formats to appeal to different customer segments, and they have unique challenges in managing an omnichannel with many retail formats. These are (1) extremely wide variety of merchandise, (2) enormous quantity of data from transaction, inventory, logistics, and customers, (3) different organization structures and management, and (4) unique organizational capabilities in each retail format. From these challenges, we could propose further research issues as follows: (1) theoretical consideration of boundary-spanning functions among retail formats, (2) international comparative analysis reflecting the different conditions in each country, and (3) clarifying the characteristics of the omnichannel shopper in the Japanese omnichannel environment.     

Effects of direct payments on rice income variability in Japan*

The effects of direct payments on rice income variability in Japan are analysed based on a balanced panel dataset of Japanese rice farms for 2012–2016. Firstly, the contribution of income components to rice income variability and the effects of a direct payment reduction are discussed by applying variance decomposition. Secondly, robust regression techniques are used to measure the correlation between direct payments and rice income variability. The originality of this paper is that it disaggregates the effects of payments using a regression analysis of the effects of direct payments on income variability for Japan. This contrasts with the existing literature on this topic, which has largely focused on European Union countries. This paper discusses to what degree the reduction in direct payments increases income variability. The results reveal that direct payments decrease Japanese rice income variability. Indeed, after controlling for various farm characteristics, we find a negative relationship between the amount of direct payments linked to rice production and rice income variability. Finally, the results suggest that reducing direct payments when the rice price is falling would increase rice income variability.
