题目: Optimal Trade Policies and Labor Markets

主讲人：吕丹 (香港中文大学)

摘要：We provide a general formula for optimal unilateral policies in multi-sector, general-equilibrium Ricardian models with various widely adopted labor market specifications.Sector-specific tariffs are summarized by a matrix of partial supply elasticities and the share of Home’s import in foreign incomes, reflecting Home’s import market power. Sector-specific export taxes depend on trade elasticities and Home’s market share in foreign con-sumption, reflecting Home’s export market power. Home imposes higher tariffs or export taxes on sectors with larger market powers. We apply the general formula to specific cases:perfectly mobile labor, imperfectly mobile labor across sectors, Ricardian-Roy models, and inefficient labor markets.
