As both the natural level of output and the New Keynesian output gap cannot be observed in practice, there is quite some debate on the question how these variables look like in practice. Rather than taking the standard approach of using a time trend or the HP-filter to obtain estimates of these...

This paper first documents the increase in the time lag with which labor input reacts to output fluctuations ("the labor adjustment lag") that is visible in US data since the mid-1980s. We show that a lagged labor adjustment response is optimal in a setting where there is uncertainty about the...

Traditional ways of analyzing the effects of monetary policy shocks via structural vector autoregressions require the use of unrealistic identifying assumptions: they either do not allow for a response of output and prices on impact of the shock, or they exclude contemporaneous values of these...

Recent research has shown that the standard labor market matching model fails to match the dynamics of US data. In particular, the model lacks sufficient propagation of shocks. This paper shows that refining the informational structure of the model leads to significant improvements along this...
