As it is now well known, in the framework of DSGE models taking into accounts agents expectations, the fully unconstrained optimal policy (the Ramsey policy) has the main drawback of being time inconsistent: the authority has an incentive to recompute the optimal policy in each period in order...

This paper shows how to use optimal control theory to derive time-consistent optimal government policies in nonlinear dynamic general equilibrium models. It extends the insight of Cohen and Michel (1988), who showed that in _linear_ models time-consistent policies can be found by imposing a...

The recent works of Gali and Gertler (1999) and Gali, Gertler, and Lopez-Salido (2001) provided evidence supporting the NKPC for the United States and the euro area. However, several econometric problems have been discussed in the literature on the empirical relevance of their results (among...

Since it burst onto the scene of mainstream monetary economics, the New Neo-Classical Phillips Curve has been the focus of two important empirical debates. First, to what extent properly measured marginal costs affect inflation dynamics. Second, to what extent purely forward looking inflation...

Many recent papers, following Gali (1999), have found a negative response of employment to a positive technology shock identified as a permanent shock to labor productivity, contradicting the prediction of standard RBC models. In a recent paper, Christiano, Eichenbaum and Vigfusson (2003) get a...

A recent literature have proposed different methods to produce second-order accurate approximation to the solutions to DGSE's from a straightforward second-order approximation of the model. Among others, Judd (2002), Jin and Judd (2002) show how to compute approximation of arbitrary order on...
