Rent control with matching economies: A model of European housing market regulation

Housing markets are thin, and consumer search for housing is costly, time consuming, and risky. Mismatches between tenants and dwellings are common in a laissez-faire market. There are scale economies in accumulating tenants and houses and then matching them up to improve welfare. In many European countries, some housing is rent controlled and rationed by public centralized matching. Waiting time, risk in rationing, and risk in matching are costs that arise from such regulation. We show that welfare improvements over laissez-faire occur if gains from centralized matching can offset the decrease in housing quality, the possible increase in waiting times, and the risks in rationing induced by rent controls. Under regulation, there is a welfare maximizing partition of the stock into free and controlled markets; and contrary to observed practice, it is often welfare improving to set controlled rents above (not below) laissez-faire, which increases the supply offered for centralized matching and the opportunity for a better match.
