Introduction to Special Issue: Topics Related to Real Estate Market Efficiency

The efficiency of the real estate market is a major concern for homeowners, investors, lenders, policymakers, and researchers. Modern academic literature has mostly moved beyond an early emphasis on formal tests of informational efficiency. The Grossman and Stiglitz (The American Economic Review 70:393–408, 1980) paradox holds that perfect informational efficiency is impossible and the joint hypothesis problem implies that market efficiency is not even testable. Instead, researchers now commonly examine the speed, accuracy, and persistence of price movements in response to new information, as the allocative efficiency of a market ultimately depends on its degree of informational (and operational) efficiency. This special issue is devoted to exploring these issues.
