In this paper, we, seek to characterize the dynamic effects of permanent technology shocks and the way in which US monetary authorities reacted to these shocks over the sample 1955(1)--2002(4). To do so, we develop an augmented sticky price-sticky wage model of the business cycle, which is estimated by minimizing the distance between theoretical, dynamic responses of key variables to a permanent technology shock and their structural VAR counterparts. In a second step, we compare these responses with the outcome of the optimal monetary policy.
