This paper extends the standard New Keynesian dynamic stochastic general equilibrium (DSGE) model to agents who cannot smooth consumption (i.e. spenders) and are affected by external consumption habits. Although these assumptions are not new, their joint consideration strongly affects some...

This paper develops and estimates a simple New Keynesian Dynamic Stochastic General Equilibrium (DSGE) model with rule-of-thumb consumers and external habits. Our theoretical model has a closed-form solution which allows the analytical derivation of its dynamical and stability properties. These...

This paper adds to the large literature on the effects of technology shocks empirically and theoretically. Using a SVEC model, we first show that not only hours but also investment decline temporarily following a technology improvement. This result is robust with respect to important data and...
