This paper examines the effects of upgrading product quality standards on product and professional labor market equilibriums when both markets are regulated. The Japanese government revised the Building Standards Act in June 2007, requiring a stricter review process for approving the plans of large-scale buildings. This regulatory change increased the wages of certified architects in Tokyo by 30 percent but did not increase their total hours worked because of an inelastic labor supply. The stricter quality standards created a quasi rent for certified architects and owners of condominiums at a cost to consumers. Evidence suggests that the new standards increased the transaction price of existing condominiums by 15 percent in the Tokyo metropolitan area.
