In open competitive tendering in Japan, one-party bid events where only one contractor submits a bid frequently occur. This situation has been criticized as hindering economic efficiency and fairness. This study uses bidding records to statistically analyze the factors that influence the number of bidders and cause one-party bids, which subsequently influence the win-reserve ratio. We found that fewer bidders participate in bidding for deals that require relationship-specific investments, resulting in a higher win-reserve ratio. In biddings with ambiguous specifications and incomplete contracts, more bidders participate, leading to a lower win-reserve ratio. Aside from these indirect effects mediated by the number of bidders, some factors directly influence the win-reserve ratio. Interestingly, indirect and direct effects conflict for follow-up deals and deal size. Thus, by highlighting deal-specific factors and differentiating between indirect and direct effects, this study brings new insights into the discussion on bidder behavior and its outcomes.

In this study, we examined the effect of the order of shortening business hours of the restaurants, which are considered a major source of spreading the novel coronavirus (COVID-19). Specifically, we empirically investigated how this order changed the nighttime light (NTL) in regions with restaurants in the Greater Tokyo area from January to June 2020. Several local governments in Japan had implemented the order to combat COVID-19. Our investigation found evidence that the order significantly decreased the NTL in regions with many restaurants, indicating the effectiveness of the order and its negative economic/business impacts on restaurants. Interestingly, this order increased the NTL in other areas, such as in residential areas. In contrast to previous studies focused on demand-side factors, our study revealed the importance of supply-side factors in explaining the impact of Japanese government policy against COVID-19 in the first half of 2020.

This study is the first to exhaustively calculate the degree of concentration in regional banking markets using the outstanding amount of loans and deposits at branches and headquarters of financial institutions in Japan. Calculating the Herfindahl-Hirschman Index (HHI) for loans and deposits for each prefecture and for each urban employment area for the period 2005–2019, we show differences in the HHI across regions and developments in these differences over time. Furthermore, we decompose the level of and changes in the HHI into two components: the contribution of the number of financial institutions and the contribution of the deviation of individual financial institutions’ market share from the mean. We also examine the extent of the increase in the HHI caused by mergers of financial institutions and its persistence. The main results obtained are as follows. First, while the HHIs for loans and deposits show an upward trend, the HHI for loans in large metropolitan areas, which was already low, continued to further decline, indicating that competition among financial institutions in large metropolitan regions, which already was severe, has continued to intensify. Second, increases in the HHI are not only due to reductions in the number of financial institutions but also to the growing variation in financial institutions’ market share. And third, while an increase in the loan HHI due to a merger of financial institutions is sustained for a certain period, the duration of such an increase tends to be shorter in regions with a low market concentration.

The article aims to show how keiretsu networks have functioned, evolved, and influenced the economy of Japan over the decades. The main research method used is an in-depth literature review, while a bibliometric analysis and the path-dependence framework support it in the selection of relevant material. The keiretsu predecessors were the zaibatsu – large family-controlled conglomerates that came into prominence during the Meiji Period. The two traditional types of keiretsu are horizontal (financial) networks and vertical (industrial) networks. The key elements of the keiretsu system are the main banks, sōgō shōsha, shachō-kai (for horizontal keiretsu), and kyōryoku-kai (for vertical keiretsu). Text network analysis reveals four main themes in the literature: “Japan and the global economy,” “financial institutions of Japan,” “the theory of the keiretsu,” and “the characteristics of the Japanese firms.” The keiretsu had a positive influence on the Japanese economy during the post-war period of high economic growth. As the economy of Japan slowed down in the 1990 s, the gains from keiretsu membership became less unequivocal – which prompted a wave of mergers and modernization.

During past shocks (e.g., the 2008–2009 global financial crisis), the services trade was found to be more resilient than the goods trade; however, the ongoing novel coronavirus (COVID-19) pandemic has restricted cross-border mobility, which is disastrous to the services trade because it often requires physical proximity between suppliers and consumers. We empirically examined the impact of COVID-19 on the services trade using quarterly data from 146 countries in 2019 and 2020. Its severity is measured according to the number of cases, the number of deaths, and an index measuring the severity of lockdown orders. We found that the pandemic had a more significantly negative impact on the services trade than the goods trade, particularly on the import side. Moreover, the extent of the impact varied among disaggregated services sectors, reflecting the nature of services. Travel services were the most severely affected, followed by transport and construction services, which are largely related to the international movement of people and goods. On the other hand, other services typically provided as cross-border supply, including computer services, experienced almost no significant effect.

We examine whether the price affects the contractor’s choice of quality using the ex-post quality evaluation data of public construction projects conducted by Ise City in Japan. Ise City employs a sealed-bid first-price auction with reserve and minimal prices in the selection of contractors. Upon completion of the project, Ise City evaluates the quality of the work using a 100-point scale score based on items such as administration, safety, time management, external appearance, and functionality. Our results show that the winning price in the auction does not affect the quality of the work. We discuss several reasons behind this finding.

We investigate how exchange rates affect the Japanese chemical industry. This industry exports sophisticated products to downstream firms. Since more complex products are less substitutable in international trade, we investigate whether they have lower price elasticities. We measure complexity using Hidalgo and Hausmann’s (2009) product complexity index. We find that price elasticities are lower for more complex chemical goods. We also find that stock returns of chemical firms that occupy vital niches in the world economy are harmed less by yen appreciations. These results indicate that exporting sophisticated products can reduce export volatility and profit volatility arising from exchange rate swings.

By combining the static and dynamic computable general equilibrium models, this paper explores the dynamic impact of future demographic changes on the Japanese economy with a particular focus on multisector production and overlapping generations. Several numerical results were obtained. First of all, the sectoral real GDPs of the aging-related sectors are expected to continue to increase due to the higher demand generated by the elderly, while the total real GDP is forecasted to start to decrease from year 2036 due to the shrinking population. Secondly, calculations show that nearly 60 million more workers will be needed in the private long-term care sector in year 2049 than in year 2018. Thirdly, if a 90 percent inflow of additionally needed labor force to the medical services sector were to be obstructed, the total real GDP would shrink by 0.064 percent. If the same inflow obstruction were to occur to the private long-term care sector, the total real GDP would shrink by 0.030 percent. Fourthly, while a negative impact of the inelastic labor mobility was seen in almost all simulations, the impact of an obstruction in the medical service sector was found to be positive for the pharmaceutical sector due to substitution effect. Finally, the inelastic labor mobility will not only reduce the Japanese economic performance but also welfare, the extent of which depends on the duration of labor immobility. Thus, it is crucial for future economic growth as well as welfare of aging Japan that the additionally needed labor inflow to all aging-related sectors occurs smoothly.

Fiscally constrained governments prefer imposing tariffs instead of providing subsidies, despite tariffs distorting markets more than subsidies. Japan’s price adjustment program is designed to support the domestic sugar industry by imposing a tariff on imports and by subsidizing domestic production using tariff revenues. This study compared the program and a subsidy scheme using benefit/cost ratios and the degree of trade distortion. The main findings and their policy implications are as follows: 1) because the benefit/cost ratio for the program is greater than one, the program would be beneficial for Japanese people, 2) the ratios and trade distortions for the two policies are similar, thus the program works well when fiscal spending is constrained, as it requires less government spending, 3) using tariffs instead of the other two policies results in a smaller benefit/cost ratio and greater market distortion, 4) people are uncertain about their preference for the program, making them more accepting of it.

This study aims to estimate the elasticity of taxable income (ETI) with regard to the net-of-tax rate, precisely in terms of potential for the margin arising from the behavioral response. We use panel data from top Japanese taxpayers in Tokyo during 1986–1989 and focus on the tax policy changes caused by the 1987–1989 comprehensive tax reform, which substantially reduced the top marginal tax rates. It is found that the ETI with regard to the net-of-tax rate is approximately 0.158–0.226, considerably lower than those for the United States and many European countries. One possible reason for the small ETI estimates is the absence of the behavioral response in terms of choice of deductions in this study.
