Who Uses Free Trade Agreements?

The utilization of ASEAN free trade agreements (FTA) is low by international standards. To clarify the reasons for such low utilization, this paper uses unique affiliate‐level data to investigate what kinds of Japanese affiliates in ASEAN are more likely to use an FTA scheme in their exporting. Our findings are as follows. First, the larger the affiliate is, or the more diversified the origins of its procurements, the more likely it is to utilize an FTA scheme in its exporting. Second, affiliates that export actively to countries with higher general tariffs are more likely to use FTA. Third, there are clear differences in FTA utilization depending on affiliates' locations and sectors.     

Spatial Cournot competition and economic welfare: a note

We investigated welfare implications in location-quantity models in a symmetric linear city. We found that when firms are not agglomerated in equilibrium, increasing the distance between firms raises (reduces) producer surplus and social welfare (consumer surplus). Moreover, central agglomeration is always optimal for consumers among symmetric locations, but not necessarily for producers. Central agglomeration can be inefficient even if it is the unique equilibrium outcome. In short, the firms are more likely to agglomerate or locate closer than what welfare maximizers would dictate, whereas they locate farther apart than what consumer surplus maximizers would recommend.     

Partial Agglomeration or Dispersion in Spatial Cournot Competition

We revisit works by Pal and Matsushima, which, respectively, present different equilibrium locations. We consider nonlinear transport costs and show that Pal's result (dispersion) is more robust than Matsushima's (partial agglomeration). Pal's result holds true for any transport cost function, while Matsushima's does not hold under strong concavity or convexity of the transport cost function. If we consider sequential move of location. Pal's result holds for any transport costs. On the other hand, Matsushima's does not hold except for linear transport cost. We also discuss welfare and show that nonlinearity of the transport cost function yields rich welfare implications.     

The Impact of Foreign Entry on Chinese Banks

Utilizing hand collected data concerning foreign ownership in the Chinese banking sector, we examine whether foreign ownership improves the efficiency of Chinese banks. Foreign banks tend to provide cooperation in retail banking rather than in corporate or private banking. We find no robust evidence of an improvement in the efficiency of an average bank that receives foreign strategic investments. However, the bank cost and profit efficiency significantly improve when foreign strategic investments provide retail banking and internal control assistance respectively to local banks. These findings suggest that foreign investment improves local bank efficiency when it transfers technologies that are lacking in local banks.     

Nonlinear behavior of the socio-economic dynamics for lake eutrophication control

To succeed in combating lake eutrophication, cooperation of local inhabitants, small factories, and farmers in reducing phosphorus discharge is very important. But the willingness of each player to cooperate would depend on the cooperation of other players and on the level of environmental concern of the society in general. Here we study the integrated dynamics of people's choice of behavior and the magnitude of eutrophication. Assumptions are: there are a number of players who choose between alternative options: a cooperative and environment-oriented option is more costly than the other. The decision of each player is affected by “social pressure” as well as by economical cost of the options. The lake pollution increases with the total phosphorus released, and a high pollution level in the lake would enhance the social pressure. The model includes a positive and a negative feedback loops which create diverse dynamical behavior. The model often shows bistability — having an equilibrium with a high level of cooperation among people and clean water, and the other equilibrium with low cooperation and polluted water, which are simultaneously stable. The model also shows fluctuation between a high and a low levels of cooperation in alternating years, cycle with a longer periodicity, or chaotic fluctuation. Conservatism of people stabilizes the system and sometimes helps maintaining cooperation. The system may show unexpected parameter dependence — the improved phosphorus removing efficiency might make water more polluted if it causes the decline in the environmental concern and cooperation among people.     

Post-restructuring performance in Japan

Peek and Rosengren (2005) showed that after the end of the bubble economy era in Japan, regulatory forbearance and perverse incentives allowed Japanese banks to engage extensively in “evergreening”. Inoue et al. (2008) also showed that, compared to out-of-court settlements in the United States, agreements on out-of-court restructuring are attained more easily in Japan. However, widespread forbearance by banks and affiliated companies in addressing the needs of distressed firms indicated a serious weakness of banks and affiliated companies in instituting discipline. This is the first empirical study to examine the performance of Japanese firms that experienced out-of-court restructuring in Japan from January 1990, when the bubble economy burst, to March 2005, when the Koizumi Cabinet declared the bad debt problems of major firms to be resolved. Our results show that important biases permitted deeply unprofitable firms to survive in Japan. This finding is similar to research by Hotchkiss (1995), who analyzed post-restructuring performance in the United States. We also find that out-of-court restructurings of troubled firms in Japan were less effective in improving profitability than restructurings under Chapter 11 in the United States. However, we find that restructurings associated with new capital injections and new outside management are more likely to lead to genuine improvement in financial performance.     

Credit Contagion and Trade Credit: Evidence from Small Business Data in Japan

The present study investigates whether credit contagion leads to a decrease in trade credit for small businesses. In 1997–1998, the Japanese economy experienced a deep recession, and the domino effect caused an increase in the number of dishonored bills and bankruptcy filings. During a period of credit contagion, the possibility of default increases for firms with more financial claims and lower cash holdings. We find that during a recession, trade payables for small businesses with higher trade receivables and lower cash holdings are reduced. The hypothesis that the effects of credit risk on trade payables are weakened is not supported.     

Loan officers and relationship lending to SMEs

Previous research suggests that loan officers may play a critical role in relationship lending by producing soft information about SMEs. For the first time, we analyze this hypothesis and find empirical evidence that indicates that loan officer activities are associated with bank production of soft information. We also find that loan officers at small banks produce more soft information than at large banks, but large banks appear to have the equivalent potential to underwrite relationship loans. Nevertheless, large banks choose instead to focus their resources on transactions lending.     

Process and context in choice models

We develop a general framework that extends choice models by including an explicit representation of the process and context of decision making. Process refers to the steps involved in decision making. Context refers to factors affecting the process, focusing in this paper on social networks. The extended choice framework includes more behavioral richness through the explicit representation of the planning process preceding an action and its dynamics and the effects of context (family, friends, and market) on the process leading to a choice, as well as the inclusion of new types of subjective data in choice models. We discuss the key issues involved in applying the extended framework, focusing on richer data requirements, theories, and models, and present three partial demonstrations of the proposed framework. Future research challenges include the development of more comprehensive empirical tests of the extended modeling framework.     

Spurious regressions in technical trading

This paper investigates the spurious effect in forecasting asset returns when signals from technical trading rules are used as predictors. Against economic intuition, the simulation result shows that, even if past information has no predictive power, buy or sell signals based on the difference between the short-period and long-period moving averages of past asset prices can be statistically significant when the forecast horizon is relatively long. The theoretical analysis reveals that both ‘momentum’ and ‘contrarian’ strategies can be falsely supported, while the probability of obtaining each result depends on the type of the test statistics employed.
