Abstract: Abstract We examine the business groups’ risk-sharing hypothesis in the Japanese Real Estate Investment Trust (REIT) market in which the unique external management system seems to be reinforcing power relationships among firms affiliated with the modern Japanese business groups, called keiretsu. We find that REITs whose sponsors belong to one of the keiretsu groups (keiretsu REITs) have significantly lower volatility of profitability than REITs whose sponsors do not belong to the keiretsu groups (non-keiretsu REITs). There is no significant difference in profitability between keiretsu REITs and non-keiretsu REITs, controlling for firm and property characteristics. The abnormal portion of the profitability unexplained by firm characteristics is also significantly lower with keiretsu REITs. We also find that the keiretsu affiliation reduces the systematic volatility of affiliated REITs, while such an effect is not observed with the idiosyncratic volatility, suggesting that the risk-sharing effect may be beneficial for the value of REITs. Using the difference-in-differences design with propensity score matching, we find that the negative impact of the Great East Japan Earthquake on the profitability was significantly smaller with keiretsu REITs than with non-keiretsu REITs. Keiretsu REITs were also able to stabilize their capital structure by shifting some short-term debts to long-term debts without increasing the cost of loans under the uncertain situation caused by the Earthquake. Keiretsu REITs were able to borrow money from their affiliated group banks even right after the earthquake, while non-keiretsu REITs seem to have struggled to secure loans from those banks.
