The literature on the government spending multiplier has implicitly assumed that an increase in government spending has the same (mirror-image) effect as a decrease in government spending. We show that relaxing this assumption is important to understand the effects of fiscal policy. Regardless...

We highlight a state variable misspecification with one accepted method to implement stochastic volatility (SV) in DSGE models when transforming the nonlinear state-innovation dynamics to its linear representation. Although the technique is more efficient numerically, we show that it is not...

I analyse the dynamics of a New Keynesian DSGE model where the financing of investments is affected by a moral hazard problem. I solve for jointly Ramsey-optimal monetary and macroprudential policies. I find that when a financial friction is present in addition to the standard nominal friction,...

This paper introduces a nonlinear certainty equivalent approximation method for dynamic stochastic problems. We first use a novel, stable and efficient method for computing the optimal policy functions for deterministic dynamic optimization problems, and then use them as certainty-equivalent...

While a widespread consensus exists among macroeconomists that the German labour market reforms in 2003-2005 have successfully contributed to the decline of the unemployment rate, critics claim that the reforms led to wage restraint and consequently consumption dampening accompanied by...
