| Outline of Final Research Achievements |
Exclusionary contracts prevent downstream firms from purchasing inputs from other upstream competitors in vertical relations, such as those between manufacturers and retailers or input suppliers and final goods manufacturers. By focusing on the incentives of individual firms, previous studies found that rational firms engage in exclusive contracts to exclude efficient upstream firms in specific situations. In this study, we conduct an analysis focusing on durable goods and on the exclusive-offer competition among existing upstream firms. Note that these situations have yet to be the focus of the previous studies. The theoretical study shows that exclusive contracts are signed to exclude rival upstream firms in such situations. In addition, we conducted an experimental analysis of offer competition for exclusive deals and found that a high exclusion rate is observed in certain situations.

| Academic Significance and Societal Importance of the Research Achievements |
排他条件付取引は，ライバルを排除する反競争的な目的で行われる可能性があるが，関係特殊的投資の促進を通じた効率性向上効果も持ち合わせている．このため，排他条件付取引の反競争性については，想定する状況ごとの判断が必要となる．本研究では，先行研究では注目されてこなかった耐久財市場や既存企業間で排他条件付取引契約の提示競争がある状況では，ライバルを排除する反競争的な目的で，排他条件付取引契約が締結される可能性があることが明らかになり，競争政策の運営において，新しい知見を与えることができた．
