題目
Corporate Environmentalism under Kantian Behavior (joint work with Ngo Van Long, McGill University)
要旨
We explore the characteristic of Kantian equilibrium on corporate environmentalism. We focus on oligopolistic firms’ investments for environmental technology and compare the level of investment under Kantian behavior with that under Nashian behavior. We demonstrate that firms invest more under Kantian behavior than at Nashian behavior and that overcompliance may happen at Kantian equilibrium.

題目
Anonymity and Equilibrium Indeterminancy in a Random Matching Model with Divisible Money
要旨
This study considers an economy in which individuals are randomly matched into pairs and play a game using a medium of exchange without knowing how much of the medium their partners have. The amount of the medium held by an individual in a match affects the set of actions available to him in that match but does not affect the payoff to be received in the match directly. This study presents a conjecture that if such an economy has one stationary equilibrium in which the medium is positively valued, then, it also has a continuum of similar equilibria. The study proposes an approach to the issue based on Fredholm’s theorem along with a working hypothesis.

題目
Multi-product Suppliers, Free Entry and Social Inefficiency
要旨
This paper investigates the social optimality of the free-entry equilibrium in an vertically linked industry with multi-product suppliers. In the upstream sector, each firm produces a certain range of products in the vicinity of its base product on a circular product space and engages in price competition a la Bertrand, and the downstream sector produces a single good under perfect competition. Using the demand function for the final good with a constant price elasticity, this paper show that with the price elasticity higher than a critical value, the number of upstream firms that enter a market is socially excessive (insufficient) if the market size for the final good is sufficiently large (small), while there is always excess entry if the price elasticity falls short of the critical value.

題目
Strategy-proofness and Double Implementation with Minimax and Maximax Strategies
要旨
This study proposes a double implementation of two solution concepts derived from minimax and maximax strategies and examines its relationship with strategy-proofness (or dominant strategy implementation). Although the combination of the two solution concepts is strictly weaker than a dominant strategy, their double implementation implies strategy-proofness when the preference domain satisfies a richness condition; consequently, their double implementation is almost equivalent to a dominant strategy implementation. Our richness condition is weaker than the condition of Sato (2013) for adjacent strategy-proofness to be equivalent to strategy-proofness, and is satisfied by the general domains based on convexity, including standard economic environments and single-peaked preferences allowing weak orders.

Output and R&D Subsidies in a Mixed Duopoly
要旨
This study analyzes a policy mix of output and R&D subsidies in a Cournot duopoly with public and private firms. We show that a pair comprising an output subsidy and an R&D tax can attain the first-best allocation if and only if either demand is linear or the public firm is fully privatized. Moreover, in a model with linear demand and quadratic costs, the output-subsidy policy is welfare-superior to the R&D-subsidy policy and partial privatization is socially optimal.

Domestic Income Transfer and Workers’ Welfare in a Dual Economy (joint with Ling Qi (Central University of Economics and Finance) and Kojun Hamada (Niigata University))
要旨
This paper investigates the welfare effects of an income transfer from urban manufacturing workers to rural agricultural workers in a closed open dual economywhere the urban manufacturing wage is fixed under the minimum wage legislation. Then we show that if the demand for the agricultural good is sufficiently weak, the utility of a manufacturing worker goes down by the transfer in both specific and mobile case. As for the agricultural workers, we show that, if the agricultural production function has a sufficiently steep and round curve with respect to labor input, they become better off by the transfer in the specific capital case. It is also show that, if the per capita agricultural production function has a steep and nearly straight curve with respect to its capital-labor ratio, they become better off in the mobile capital case. Therefore there is no transfer paradox to occur. In order for these results to be true, however, it is required that the capital-labor ratio of the urban area is greater than that of the rural area. This is a sufficient condition for labor movement adjustment as well as Walrasian adjustment process to be locally stable in the mobile capital case.

共有再生可能資源における消費者の選好の異質性と貿易
要旨
排他的経済水域の導入後も、鮪鰹類や鰻等のように国際的に共有された再生可能資源は、その利用と貿易・管理については依然として、国際的な共通合意が政策的にとれない場合も少なくない。こうしたものを取り上げた研究は近年でもRus (2012)やTakarada et al. (2013)等、行われてきた。それらの多くが、各国の再生可能資源を同一のものとみなして研究が行われてきた。それとは対照的に、多様な資源を取り上げた研究にはQuaas and Requate (2013)等がある。ところで、工業品などと異なり、水産資源に代表される再生可能資源では、その産地の影響が払拭されにくく、各国の消費者の一部はその違いをよく似たないし同じ魚種・資源に対しても気にする傾向がある。従来はOgawa (2014, WP)等のように、それらは水域の違いが大きいと扱われてきた。しかし、畜養鰻等のように、資源の出所は同じでもその育てる産地次第で、一部の消費者が別物と見なすことがある。日本などの水産靴の輸入大国でも水産物の輸出が検討されることがあるが、これはそうした産地の違いを考慮しないと扱えなくなる。そこで、本研究では国際的に共有された再生可能資源のある一般均衡での貿易モデルにおいてその貿易と管理の在り方について検討する。リカード・モデル以来、線形的なモデル構成では労働賦存量でなく技術比率が貿易パターンを決めることが知られていて、それはTakarada et al. (2013)でも確認されてきた。しかし、国内外での資源財に対する一部の消費者の異質性を考慮すると、共有資源財の純輸入国からも資源財の輸出が行われうる。この境界の価格比率に技術の比率が影響するようになる。このとき、貿易パターンの決定要因には漁獲技術だけでなく非資源財の効率労働単位に換算した労働賦存量が影響することが、リカード型を踏襲したTakarada et al. (2013)モデルを基に一部消費者における選好の異質性を入れた場合に明らかになった。これは、リカード型と新貿易理論等の折衷的な側面であり、貿易パターンの予測に大きな影響がある。これを踏まえて更に貿易や管理などの影響を取りあげる。

題目
Gravity with Multiple Tariff Schemes (joint with Kazunobu Hayakawa)
要旨
In this paper, we contribute to the literature on gravity analysis by explicitly incorporating both most favored nation (MFN) rates and regional trade agreement (RTA) rates. Our gravity equation takes into consideration the fact that all exporters do not necessarily utilize RTA schemes when exporting even to RTA partners. We applytariff line level data on the world-wide trade to this gravity equation. As a result, we find the significantly negative coefficient for the ratio of RTA rates to MFN rates. Specifically, the introduction of duty0free RTA rates (i.e., the reduction of the ratio from one to zero) increases trade values by 18-30%, depending on specifications, Using our estimates, furthermore, we conduct the simple simulation on the effect of the subsequent reduction of RTA rates on trade.

Firm-Level Utilization Rates of Regional Trade Agreements: Perspective from Importers (joint with Nuttawut Laksanapanyakul and Taiyo Yoshimi)
要旨
While the previous theoretical studies have examined exporter’s choice of tariff schemes under keeping settings for importers as simple as possible, the empirical analysis on regional trade agreement (RTA) utilization is in general possible by employing import data. In order to better link the empirical analysis with the theoretical model, this paper constructs the model that sheds light on the role of not only exporters’ characteristics but also importers’ characteristics in RTA utilization. As a result we derive some propositions on RTA utilization rates (i.e., the share of imports under RTA schemes in total imports) at both an import firm-product-level and a product-level. Finally, we found that these theoretical predictions are supported by the highly-derailed import data in Thailand from Australia from 2007 to 2009.

題目
Benefits of Home Currency Invoicing (joint with Kazunobu Hayakawa & Nuttawut Laksanapanyakul)
要旨
We present a model of endogenous choice of import frequency and invoice currency to infer the benefits of home currency invoicing. In the model, those benefits are represented by fixed costs of exchange rate risk management paid by importers when they work with foreign currency invoicing. Using a very detailed dataset on Thai imports, we show that those benefits of average Thai importer range between 7.3% (1,500 USD) of one-time shipment value in our most conservative specification and 17.1% (3,600 USD). Those benefits become larger when the share of the export country currency in daily global foreign exchange market turnover is lower, or the export country is on of the partners of Thailand's regional trade agreements. Further, we find that frequency of shipments is higher and the value per shipment is smaller for transactions priced in buyers’ currency than those not priced in it. Our model provides a rationale for these empirical findings.

Voice Undermines Voluntary Cooperation: An Experimental Study for an Incomplete Employment Contract
要旨
To examine impacts of a pre-play communication in principal-agent relationships between workers and firms with hidden action, we conducted laboratory experiments on gift exchange games with and without a “voice” option. In the one with a “voice” option, the worker must state a payoff-irrelevant request for his/her wage before the firm decides his/her wage offer. Comparing experimental results with and without the option, we find that the pre-play communication of such the option undermines reciprocity of the workers regardless of the wage levels offered by the firms. The deterioration results in shrinking economic surplus in their principal-agent contracts.

Fertility, Mortality, and International Trade Pattern within a Heckscher-Ohlin Framework
要旨
This paper examines a two-country dynamic general equilibrium model with endogenous fertility and mortality. We show that the introduction of endogenous demographic change brings about new properties in long-run dynamics. After an analysis of the existence, uniqueness, and local stability of the long-run equilibrium, we examine each country’s long-run trade pattern and gains from trade in the long-run.

Imitation versus Innovation Costs: Patent Policies under Common Patent Length
要旨
This paper investigates the interaction between innovation and imitation costs for heterogenous ideas (industries). Int analyzes the effect of various patent-related policies under the common patent length across different industries. It also looks at a policy that will strengthen trade secrets such as the Soleau envelope policy. Under the common term of patent with moderate assumption about the joint distribution of costs, the model predicts the existence of imitating products which are successfully invented around the original patent.

Determinations of International-Conference Venues: From Data of Japanese Cities
要旨
This paper attempts to investigate which of 14 major Japanese cities attracted more international conferences than others from 1998 to 2013 and why they did it. From data of international conferences held in Japan during this period, two interesting observations are arisen. First, although metropolitan Tokyo attracted more international conferences than any other cities for all sample years, there are large variations among other cities; in some cities the number of international conferences increased rapidly, while those stagnated in some other cities. Second, impacts of the Great East Japan Earthquake seem to be different among cities; cities in western Japan got positive effects, but not all eastern Japanese cites were affected negatively. Some primitive estimates show a positive effect of economy size measured by city population and a negative effect of yen-dollar exchange rate on the numbers of international conferences held in Japan. The second estimated result seems to contradict with a recent observation of increasing foreigners visiting Japan due to weaker yen.

Privatization Neutrality Theorem When a Public Firm has Different Objectives than Welfare Maximization
要旨
This paper investigates the privatization neutrality theorem when a public firm has different objectives than welfare maximization. The privatization neutrality theorem claims that social welfare is exactly the same before and after privatization when the government gives the optimal subsidy to both public and private firms. In contrast to the existing literature that assumed the uniform subsidy to public and private firms and claimed that this theorem does not hold, we demonstrate that if the discriminatory subsidy rates are adopted between public and private firms, the privatization neutrality theorem recovers in many cases. Especially, we present the paradoxical result that when the subsidy policy itself causes the distortion on income distribution, the privatization neutrality theorem always holds, while the situation in which the theorem holds is limited without such a distortion. Our result insists that the government can maximize the social welfare by appropriatelyimplementing a discriminatory subsidy policy even if there is the distortion that the subsidy policy causes on the distribution.

A Shortest Route around the Diamond Paradox
要旨
This paper considers a random-matching economy in which utility from consuming one unit of indivisible good and disutility from producing it depend on the length of time that has elapsed after the preceding consumption and preceding production respectively. It also assumes that sellers post prices without knowing buyers’ private characteristics. Then, a parametric example of stationary equilibrium is provided which exhibits equilibrium price dispersion explicitly.

Liner Shipping Alliance and Antitrust Immunity
要旨
This paper examines i) the effects of alliances on load capacity and shipping charges, ii) whether excess capacity arises, in particular, in the presence of uncertainty on demand for marine transportation, and iii) governments’ decision making on antitrust immunity. Using a simple three-country two-duopoly-market model, we find that alliances may increase load capacity and, accordingly, decreases shipping charges. We also find that load capacity is insufficient at market equilibrium in terms of global welfare when there is no uncertainty, while the load capacity of more efficient shipping liners may be excessive when there is uncertainty. Moreover, we demonstrate that the government of a country in which there is a more efficient shipping liner prefers pro-competitive policies.
