Efficiency, scale economies, and the risk/return performance of real estate investment trusts

Estimates from a directional output distance function are used to construct a risk/return frontier that defines the best-practice management technology for Real Estate Investment Trusts (REITs). We model REIT performance as a production process in which each REIT produces a desirable output ( return) and an undesirable output (risk) using inputs of managerial effort and financial capital. The results suggest that ignoring the effects of risk yields a management technology that is significantly different from one that incorporates risk. In addition, market valuation is inversely related to inefficiency and directly related to leverage.
