Sticky wages and rule of thumb consumers

I introduce sticky wages in the model with credit constrained or “rule of thumb” consumers advanced by Galì, Valles and Lopez Salido (2005). I show that wage stickiness i) restores, in contrast with the results in Bilbiie (2005), the Taylor Principle as a necessary condition for equilibrium determinacy; ii) implies that a a rise in consumption in response to an unexpected rise in government spending is not a robust feature of the model. In particular, consumption increses just when the elasticity of marginal disutility of labor supply is low. Results are robust to most of Taylor-type monetary rules used in the literature, including one which responds to wage inflation.
