An experimental examination of interbank markets.

We use experimental methods to evaluate a simplified interbank market. The design is a laboratory adaptation of the analysis of interbank market fragility by Allen and Gale (J Eur Econ Assoc 2:1015–1048), and features symmetric banks who allocate deposit endowments between cash and illiquid assets prior to the incidence of a shock. Following the shock liquidity-deficient banks trade assets for cash. Treatments include variations in the shock type, as well as alterations in the range of permissible asset prices. Consistent with Allen and Gale, we find that while interbank trading substantially increases investment activity, the markets are frequently characterized by price variability and a stochastic distribution of investment outcomes.
