「金融機関の業績に顧客経営支援が及ぼす影響に関するシミュレーション分析」
要旨
Currently, profitability is one of the most important issues in Japanese regional bank management. In the situation of low interest rate, supporting to customer firm management have practiced as a means of revenue improvement, because main revenue source of regional banks is loans to customer firms.
However, little is known about the relationship between supporting to customer and the profitability of regional bank.
This study analyzes this relationship by using computer simulation. To simulate, we model a regional bank’s financing and supporting activity and plural firms’ administrative activity.
The result of simulation shows that the relationship between supporting and profitability of regional bank vary depending on degree of environmental change, supporting ability of regional bank, and selection criterion of supporting firms.

“The Incentive Effect of Coarse and Refined Reporting: Theory and Experiment”
 joint with Yukihiko Funaki, Edward Halim and Yohanes E. Riyanto
要旨
We compare the incentive effect of two-grade reporting rules, namely, coarse and refined reporting. As a backdrop, we consider students whose performance in an exam will be disclosed to a potential employer. The disclosure rule is either a coarse-reporting in the form of pass or fails grade or a refined-reporting in the form of a raw score between 0 and 100. We are interested in analyzing which reporting rule would motivate students to work harder? Existing theories provide two predictions. First, a refined-reporting will provide a stronger incentive than a coarse-reporting if the former can better reflect the differences in effort levels of students with varying abilities. Second, a coarse-reporting provides a stronger incentive than a refined-reporting if the former allows a mediocre ability type to be pooled together with better types. We bring these theoretical predictions into a laboratory economic experimental test and show that subjects' behavior is consistent with the first prediction. Our result sheds some light on the optimal design of performance evaluation.

"How does risk preference change under the stress of COVID-19? Evidence from Japan"
「新型コロナのストレスによって、リスク選好はどのように変化したか?」
要旨
Though recent studies have reported that risk preference changes with large events, they have not reached a consensus on its direction. We collected panel data of Japanese individuals in five waves over three months when COVID-19 spread and then dwindled. By measuring risk preference through questions on the willingness to pay for insurance, we found that individuals became more risk tolerant over the period, which may be interpreted as “habituation” to repeated stress, as is known in neuroscience. Moreover, people were more averse to mega risk than moderate risk, as the former demonstrated stronger correlation with the perception of COVID-19.

論題
“The Intrinsic Value of Decision Rights and Reciprocity”
要旨
This study examines how intrinsic values of owing decision rights change when people are placed in a reciprocal environment. In recent years, an allocation of decision rights in firms has become an important issue in organizational management. Job specific theory suggests that intrinsic motivation through a sense of psychological ownership can increase organizational productivity. Recent researches in experimental economics also have shown that the decision right is one of the key factors for organizational productivity. As for putting the decision rights in opponent's hands, previous experimental research has shown that reciprocal relationship within memberships lead to decrease productivity due to averse being controlled. However, the relationship between owning decision right and reciprocity has not yet been clarified. Thus, we designed an experiment to test whether reciprocal environment affect intrinsic values of decision rights. Our findings indicated that people who were assigned in reciprocal treatment had an altered value for owing decision rights. Results in this paper provides new insights into the relationship between an allocation of decision rights and reciprocity, and thus may be relevant to actual organizational design.

“The Impact of Test Score Labels on University Choice: A Regression Discontinuity Design Approach”
要旨
We used data from Japanese university entrance exams to examine how the test result score labels affect students' application behavior. Students know their raw score (a continuous variable) and the score label (a discrete variable) that indicates their likelihood of success after the first test at the same time. We used a regression discontinuity design to show that score labels affect students' application behavior, with behavior jumping around the score label threshold. We further test for the heterogeneity of the jumps, taking advantage of the large data set.

“College Education and Income Contingent Loans in Equilibrium: Theory and Quantitative Evaluation” (with Karol Mazur)
要旨
This paper investigates the welfare and efficiency implications of income-contingent loans (ICLs) for financing risky college graduation. We show that the laissez-faire allocation is constrained inefficient. Furthermore, we show that although ICLs can restore the second best efficiency of the economy, the social planner may achieve the same outcomes using progressive income tax systems. Building on these insights, we construct an overlapping generations life-cycle economy with heterogeneous agents and calibrate it to the US education and labor markets. While the current design of ICLs induces significant redistribution across wealth-ability groups, it does not increase overall utilitarian welfare, as it is largely substituted by the existing progressive income tax system.

“The Cost of Gaming in Quota Contracts”
要旨
This paper studies the effect of system gaming in the dynamic moral hazard model. It is well known that the gaming is an important problem when firms use a nonlinear incentive contract such as quota-based contracts.However, it is not known how the gaming affects the type of the optimal contract. In this paper, we characterize the optimal incentive contract and show that if the agent's productivity is relatively high, quota-based contracts is more profitable for firms than linear contract even when the agent can manipulate outputs. Moreover, we compare this gaming situation with non-gaming situation in which the agent can not game the system in order to investigate the effect of gaming. We also show that if the agent is less productive, then the gaming effect is more profitable for firms.

論題
"Deep Regional Trade Agreements and Cross-border Technology Transfer: Theory and Evidence"
要旨
In this study, we examine whether deep regional trade agreements (RTAs) facilitate cross-border technology transfer. As a mode of technology transfer, we focus on licensing. We first derive a micro-founded structural gravity equation for cross-border licensing from a model in which heterogeneous firms choose to supply their goods to foreign markets by exports, foreign direct investment, or licensing. We show several comparative statics results regarding the effects of changes in fixed costs of serving the destination country, the freeness of trade, and the strength of intellectual property right (IPR) protection on exports of licensing fees. We then empirically test predictions from our model by using data on bilateral exports of royalties and licensing fees for 181 countries/regions for the period 1995-2012. Various dummy variables are used to measure the impact of shallow and deep RTAs. Consistent with our theoretical prediction, we find that a shallow RTA without IPR provision may reduce total exports of licensing and that a deep RTA with legally enforceable IPR provision will increase total exports of licensing. The net effect of forming a deep RTA is positive.
