| 2020 | Standards Policy and International Trade: Multilateralism versus Regionalism | 共著 | |
| Journal of Public Economic Theory ， Wiley ， Volume 22, Issue 5 ， pp.1420-1441 ， 2020/09 | |||
|
概要（Abstract） We develop a simple model of policy coordination on domestic standards and examine whether domestic standards policy can lead to regional and multilateral harmonization of standards under the principle of national treatment. This paper focuses on mandatory product and process standards affecting the characteristics of a final good that control negative consumption externalities (e.g., vehicle emissions control and safety standards, restrictions on the use of pesticides for agricultural goods, and safety standards for electrical products). Only the products that meet a country’s national standards are allowed to circulate in that country’s market. Raising standards reduces negative externalities caused by consumption of a traded good but increases firms’ costs. We use the core as the solution concept. A standards regime is considered to be in the core if it is not blocked by any coalition within countries. The main finding is that a multilateral agreement on standards that maximizes world welfare is only in the core if externalities are local or slightly transboundary. Otherwise, only a regional agreement on standards is in the core. As extensions, we consider many and asymmetric number of firms, asymmetry in market size, fixed costs for different standards, and a multilateral agreement on different standards. |

| 2020 | Shared Renewable Resources and Gains from Trade under Technology Standards | 共著 | |
| Review of Development Economics ， Wiley ， Volume 24, Issue 2 ， pp.546-568 ， 2020/05 | |||
|
概要（Abstract） Using a two-country, two-good model of international trade, we examine gains from trade and strategic interaction in resource management among countries that share renewable resources such as fishery stocks. Two goods are a resource good, which is the harvest of the shared stock, and some other good that may be thought of as manufactures. The productivity of the resource good depends on harvesting technology and the stock level. This paper focuses on technology standards (e.g., restrictions on fishing gears, vessels, areas, and time) over other methods for resource management because they are most commonly implemented in fisheries. Technology standards are modeled as a restriction on the harvesting technology; that is, under strict technology standards, firms exploit resources as if they are using inferior harvesting technology. We show that an opening up of trade may reduce the shared stock and cause steady-state utility to decrease in a resource-good importing country and increase in a resource-good exporting country. Strikingly, when the shared stock is in jeopardy (a high demand for the harvest), steady-state harvest is maximized after an opening up of trade by what we call multilateral resource management in this paper and both countries gain from trade. |

| 2017 | Trade and the emissions trading system in a small open economy | 共著 | |
| Environmental Economics and Policy Studies ， Springer ， Volume 19 Issue 2 ， p. 391～403 ， 2017/04 | |||
|
概要（Abstract） To control greenhouse gas emissions efficiently, we should regulate all pollution emission sources in the economy equally. However, in the real world, environmental regulations differ by sector. Using a small open economy model, this paper examines how the enforcement of an economy-wide emissions trading system (ETS) (i.e., uniform environmental regulation) affects welfare under a trade policy, where the government initially implements different environmental regulations across sectors. It is important to consider this relation between environmental regulations and trade policy because countries tend to impose weak environmental regulations in sectors facing global competition often protected by import tariffs. We find that an economy-wide ETS may harm a small open economy even under a low import tariff rate as long as the environmental regulation in the exporting industry is weaker than in the importing industry. To avoid welfare deterioration, the government should then decrease the import tariff rate in line with mitigation of the sectoral differences in environmental regulation. |

概要（Abstract） 小国開放の一般均衡モデルを用いて、産業間で汚染の相互作用がある下で、貿易利益および汚染を削減する環境技術の導入の効果を分析している。汚染産業から排出される汚染は、環境水準に敏感な産業（例えば、農業）の生産性を低下させる。本モデルでは、両財とも生産される設定のために、汚染の影響はいつも存在する。主な結果は以下の通りである。第一に、自由貿易は、貿易パターンと環境税の水準によっては、小国の経済厚生を悪化させる。第二に、汚染を減らす環境技術の導入によって、環境税が最適に課されていなければ、小国の厚生が悪化する可能性があることを示した。特に、政府が汚染産業に厳しい規制をして、環境に敏感な産業の生産を奨励しているときに、この結果は生じやすい。 |

| 2011 | Competition Policy and Merger Regulation: Protecting Consumers and Promoting Mergers | 共著 | |
| 南山経済研究 ， 南山大学経済学会 ， 第26巻／第1号 ， pp.1-21 ， 2011/06 | |||
|
概要（Abstract） We examine horizontal mergers by embedding the prophylactic nature of merger regulation such that the antitrust authority investigates substantial mergers before their consummation to preserve pre-merger welfare. In order for mergers to be approved, the merged firm maximizes its profit subject to a certain welfare constraint which works as merger remedies imposed by the authority. Without cost synergies, we show that contrary to conventional wisdom, the market share for profitable mergers is low under strict merger regulation, while it is high under weak regulation. Mergers harm non-merged firms but improve social welfare through profitable mergers under a consumer welfare standard. |

| 2008 | Horizontal Merger and Merger Remedies in Antitrust Law: A Unified Explanation of Regulatory Constraints under the Linear Demand | 共著 | |
| 新潟大学経済学年報 ， 新潟大学経済学部 ， 第33号 ， p.15〜38 ， 2009/01 | |||
|
概要（Abstract） The antitrust regulator often imposes a merger remedy on a horizontally merged firm in order to remove the anti-competitive effect of the merger. From the economic viewpoint, a merger remedy is a kind of regulatory constraint. This paper analyzes how various kinds of regulatory constraints affect the merged firm's profit in the linear demand model. We show that various forms of regulatory constraints are replaced by the simple total supply constraint. We graph the relationship between regulatory constraints and the corresponding total supply constraint. |

概要（Abstract） 地球温暖化をはじめとする国際協調が不可欠な環境問題の解決策の1つとして、環境援助の役割は重要である。本稿の目的は、環境援助に関する理論研究を概観して議論を整理するとともに、今後の研究を展望することである。一般均衡の貿易モデルを用いた研究に焦点を当てており、この枠組みには産業間の相互作用を考慮に入れることができる利点がある。環境汚染をモデル化する際の留意点を示すとともに、環境政策の下での技術移転の効果を分析する。 |

概要（Abstract）
一般的な多段階のシュタッケルベルグ・モデルを用いて、利潤の高まる合併について考察している。既存研究では一般的な場合の分析はされていなかった。この研究で、第一に、合併が利潤を高める一般的な条件を提示することができた。第二に、より高い利潤をもたらす合併の形態について条件を導出した。第三に、社会的厚生への合併の効果について分析を行った。 |
