I outline a simple roadmap for work in micro-founded models. Rather than abandoning the route to further micro-foundations and returning to ad hoc economics, the techniques we have used over the past two decades to develop micro-founded business cycle models will allow us to develop models with...

This paper examines the consequences of (S, s) pricing rules in a dynamic economy with heterogeneous costs of price adjustment. We construct the stationary distributions for aggregate output and prices for our model economy. As a result of our assumption of heterogeneous costs we find that: (i)...

This paper examines the consequences of introducing firm specific capital into a selection of commonly used sticky price business cycle models. We find that modelling firm-specific capital markets greatly reduces the response of inflation to changes in average real marginal cost. Calibrated to...

We re-connect money to inflation using Goodfriend and McCallum's (2007) model where banks supply loans to cash-in-advance constrained consumers on the basis of the value of collateral provided and the monitoring skills of banks. We show that when shocks to monitoring and collateral dominate...
