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...

Under fairly basic rationales, this paper provides a more general microstructure model of price quotation in an order driven market. Specifically, as an extension of Handa and Schwartz (1996), we decompose the equilibrium of the bid-ask spread, which is derived as a function of the weighted...

This paper provides a micro-foundation of the behavior of the banking industry in a Stochastic Dynamic General Equilibrium model of the New Keynesian style. The role of banks is reduced to the supply of loans to ¯rms that must pay the wage bill before they receive revenues from sell- ing...
