We study the existence and uniqueness properties of monetary policy with limited commitment in LQ RE models. We use a New Keynesian model with debt accumulation in the spirit of Leeper (1991) as a `lab', because this model generates multiple equilibria under pure discretion, and under full...

We study discretionary equilibria in dynamic linear-quadratic rational expectations models. In contrast to the assumptions that pervade this literature we show that these models do have multiple equilibria in some situations. We demonstrate the existence of multiple discretionary equilibria by...

Discretionary policymakers cannot manage private-sector expectations and cannot coordinate the actions of future policymakers. As a consequence, expectations traps and coordination failures can occur and multiple equilibria can arise. To utilize the explanatory power of models with multiple...

The overall aim of the research presented in this thesis is threefold: To empiricallyexamine monetary transmission to UK retail mortgage rates; to examine whyfixed versus variable rate mortgage lending differs across EU-15 countries; and to build a DSGE model which can be used for analysing...
