This paper proposes a monetary model with firm entry as a means for alleviating the difficulties of real business cycle models in reproducing the smoothness and persistence of macroeconomic variables together with the volatility of profits and markups. Simulations show that my baseline model...

We consider an economy where the oil price, industrial production, and other macroeconomic variables fluctuate in response to a variety of fundamental shocks. We estimate the effects of different structural shocks using robust sign restrictions suggested by theory using US data for the 1973-2007...

In a situation where agents can only observe a noisy signal of the shock to future economic fundamentals, SVAR models can still be successfully employed to estimate the shock and the associated impulse response functions. Identification is reached by means of dynamic rotations of the reduced...
