“…Some are based on the traditional approach of modeling of coordination failures in terms of multiple equilibria (Sachs, 1984(Sachs, , 1995Zettelmeyer, 2000;Jeanne and Wyplosz, 2001;Jeanne and Zettelmeyer, 2002). In more recent models, this modeling strategy is replaced by the "global games" approach, in which there is a unique equilibrium which may or may not involve a run on reserves, and in which the probability of a run depends on the available liquidity (Rochet andVives, 2004, Morris andShin, 2006;Corsetti, Guimarães and Roubini, 2006;Kim, 2006Kim, , 2007. It is possible to introduce an effort variable in those models and study the impact of IMF lending on policy incentives.…”
