The authors estimate the dynamic stochastic general equilibrium model of Christiano, Eichenbaum, and Evans (2005) on U.K. data. Their estimates suggest that price stickiness is a more important source of nominal rigidity in the United Kingdom than wage stickiness. Their estimates of parameters governing investment behavior are only well behaved when post-1979 observations are included, which reflects government policies until the late 1970s that obstructed the influence of market forces on investment.
