In a recent paper, Mertens and Ravn (2010) study the effects of anticipated fiscal policy shocks in a structural vector autoregressive model. The authors maintain that (i) the lag polynomial associated with news shocks is a cyclotomic polynomial and (ii) the matrix B(L) which transforms a...

This paper integrates a money and credit market into a static approximation of the baseline New Keynesian model based on a money-and-credit-in-the-utility approach, in which real balances and borrowing contribute to the household's utility. In this framework, the central bank has no direct...

This paper studies the volatility implications of anticipated cost-push shocks (i.e. news shocks) in a New Keynesian model under optimal unrestricted monetary policy with forward-looking rational expectations (RE) and backward-looking boundedly rational expectations (BRE). If the degree of...

This paper studies the volatility implications of anticipated cost-push shocks (i.e. news shocks) in a New Keynesian model with hybrid price setting both under optimal unrestricted and discretionary monetary policy with flexible inflation targeting. If the degree of backward-looking price...

This paper explores and quantifies the role of endogenous firm entry in amplifying and propagating shocks to the economy. To this end, we estimate two DSGE models on US data with Bayesian methods: one model with endogenous firm entry and translog preferences and one model without. Both models...

A recent theoretical literature highlights the role of endogenous firm entry as an internal amplification mechanism of business cycle fluctuations. The amplification mechanism works through the competition and the variety effect. This paper tests the significance of this amplification mechanism,...

Dieser Beitrag untersucht anhand eines Modells für eine kleine Währungsunion, die simultan durch angebots- und nachfrageseitige Asymmetrien gekennzeichnet ist, welche dynamischen Wirkungen von der Geldpolitik, der Fiskalpolitik sowie ausländischen Zinsänderungen auf die Union als Ganzes...

Barro-Gordon Revisited: Reputational Equilibria in a New Keynesian Model The aim of this paper is to solve the inconsistency problem à la Barro/Gordon within a New Keynesian model and to derive time-consistent interest rate rules of Taylor-type. We find a multiplicity of time-consistent rules....

This paper investigates optimal policy in the presence of anticipated (or news) shocks. We determine the optimal unrestricted and restricted policy response in a general rational expectations model and show that, if shocks are news shocks, the optimal unrestricted control rule under commitment...
