This paper proposes a method and a toolkit for solving optimal policy with imperfect commitment in linear quadratic … monetary policy. We apply our method to the Smets and Wouters (2007) model, where we show that imperfect commitment has …

optimal contracts with and without commitment and derive an exclusion restriction that is useful to identify the relevant … commitment scenario. The empirical analysis takes advantage of a data set from Spanish soccer player contracts. Our test rejects … the commitment hypothesis, which entails the acceptance of the existence of contractual incompleteness in the data. We …

Then, we relax the commitment assumption, and we show how to determine numerically whether …, Commitment, Time-consistency, Ramsey equilibrium, Markov perfect equilibria, Sustainable equilibria. …
