| 1. | Ryoichi Imai, Tax Wedge and Job Distribution with Directed Search, Search and Matching Theory Workshop 2018 Fukuoka Japan, 2018.03, [URL], In a model with two types (good and bad) of jobs and directed search, the effect of taxation is explored. If both the sectors are taxed at an uniform rate, the policy is irrelevant for the distribution of good jobs and bad jobs, or the welfare distribution between workers and firms.

| 2. | Ryoichi Imai, Resale with multiple inventory, Singapore Search and Matching Workshop, 2014.05, [URL], I present a model of the resale market in which middlemen hold multiple inventory. In the economy, there are a new good market and a resale market. Trades in the resale market is mediated by middlemen. There are two sides of the resale market. In the buy side, trades are frictionless in the sense that consumers can imediately sell their used goods to middlemen, which is the gain to use the resale market. In the sell side, however, trades are frictional in the sense that meddlemen match demand to supply between buyers and sellers.
