Outline of Final Research Achievements

Previous studies in economic growth have been considering the situation in which producing firms and households can trade goods and labor directly and did not explicitly introduce intermediate agents who have essential roles in actual market transactions. However, recent innovations in information technology and the rise of new transaction technologies suggest that improved market mediation could affect economic growth or possibly give rise to a bubble-like phenomenon. In this project, three research institutes in Japan collaborated with Tinbergen Institute in Netherland to conduct related research.

Academic Significance and Societal Importance of the Research Achievements

市場仲介や市場取引は、情報や知識の伝播を促進する。知識の蓄積は経済成長の源泉であり、その意味でも、市場仲介や市場取引の重要性が明らかになった。一方、市場仲介や情報の伝播がバブル的な資産価格の状況を生み得ることや、家計がリスクに関する情報を急激に得ると消費や雇用が抑制され得ることも明らかになった。これらの両面性を踏まえつつ、適切な政策設計を行うことの重要性が示唆される。
