“…As a consequence, no depositor knows if the other two depositors are connected or not. 6 A key element of the model is that when the depositors decide, they may not be sure of the payo¤ they will receive. For instance, if a patient depositor at the …rst position waits, then her payo¤ depends on what the other patient depositor does (i.e., c 1 0 2 fc 00 ; c 01 g).…”

“…Her decision may follow either two withdrawals (Y 3 = f1; 1g) or a waiting and a withdrawal (Y 3 = f1; 0g). In 6 Given the nature of bank runs it seems reasonable to assume that depositors do not know exactly what other depositors know. However, the theoretical result also holds when network structure is common knowledge.…”

Do Social Networks Prevent Bank Runs?

We develop, both theoretically and experimentally, a stereotypical environment that allows for coordination breakdown, leading to a bank run. Three depositors are located at the nodes of a network and have to decide whether to keep their funds deposited or to withdraw. One of the depositors has immediate liquidity needs, whereas the other two depositors do not. Depositors act sequentially and observe others' actions only if connected by the network. Theoretically, a link connecting the …rst two depositors to decide is su¢ cient to avoid a bank run. However, our experimental evidence shows that subjects'choice is not a¤ected by the existence of the link per se. Instead, being observed and the particular action that is observed determine subjects'choice. Our results highlight the importance of initial decisions in the emergence of a bank run. In particular, Bayesian analysis reveals that subjects clearly depart from predicted behavior when observing a withdrawal.JEL Classi…cation: C70, C90; D85; G21

“…7 Madies (2006) shows that sunspot bank runs can occur and that a suspension of convertibility or a full (as opposed to partial) deposit insurance may be required to prevent bank runs. Garratt and Keister (2009) show that when liquidity demand is not subject to stochastic shocks, panic-driven bank runs are unlikely to occur. With stochastic liquidity shocks, however, self-fulfilling bank runs are frequent.…”

Acknowledgements Abstract:We study experimental coordination games to examine through which transmission channels, and under which information conditions, a panic-based depositor-run at one bank may trigger a panic-based depositor-run at another bank. We find that withdrawals at one bank trigger withdrawals at another bank by increasing players' beliefs that other depositors in their own bank will withdraw, making them more likely to withdraw as well. Importantly though, observed withdrawals affect depositors' beliefs, and are thus contagious, only when depositors know that there are economic linkages between their bank and the observed bank.JEL classification: D81; G21; G28

“…Notably, in all of these cases the banks that suffered the run were fundamentally healthy, bad news about another bank sparked the run. Experimental evidence also suggests that observability plays an important role in the emergence of bank runs (see, for example, Garratt and Keister, 2009;Schotter and Yorulmazer, 2009;Kiss et al, 2012). Moreover, Kiss et al (2014) study a small-scale environment resembling the Diamond-Dybvig setup in which bank runs are caused by coordination problems.…”

“…More information about previous decisions seems to reduce the likelihood of bank runs. In Garratt and Keister (2009) and Kiss et al (2014) there were no fundamental problems with the bank and it was common knowledge, so there fundamental problems or negative information about the bank extracted from the behavior of other depositors cannot be behind the runs.…”
