Using a dynamic stochastic general equilibrium (DSGE) model that accounts for credit constraints, we study the effects of fiscal stimulus on the macroeconomy. We show that the presence of credit constraints results in larger fiscal multipliers than indicated by the standard DSGE models. If...

We investigate optimal monetary policy design using a New Keynesian model that accommodates liquidity frictions. In this model, unlike the standard New Keynesian model, the central bank faces a trade-off between inflation and output stabilisation. Optimal policy requires a temporary deviation...

In a recent paper, Michael Kiley argued that the Calvo model of price adjustment is both quantitatively and qualitatively different from the Taylor model. What we show is that Kiley (along with most other people) are choosing the wrong parameterization to compare the two models. In effect they...

This paper adopts the Impulse-Response methodology to understand inflation persistence. It has often been argued that existing models of pricing fail to explain the persistence that we observe. We adopt a common general framework which allows for an explicit modelling of the distribution of...

n this paper we develop the Generalize Taylor Economy (GTE) in which there are many sectors with overlapping contracts of different lengths. We are able to show that even in economies with the same average contract length, monetary shocks will be more persistent when there are longer contracts....

We estimate and compare two models, the Generalized Taylor Economy (GTE) and the Multiple Calvo model (MC), that have been built to model the distributions of contract lengths observed in the data. We compare the performances of these models to those of the standard models such as the Calvo and...

This paper considers the monetary policy implications of a model that features input-output connections between stages of production, so that a distinction between CPI inflation and PPI inflation arises. More specifically, this paper addresses the policy conclusion by K. Huang and Z. Liu [2005,...

The popular Calvo model with indexation (Christiano, Eichenbaum and Evans, 2005) and sticky information (Mankiw and Reis, 2002) model have guided much of the monetary policy discussion. The strength of these approaches is that they can explain the persistence of inflation. However, both of these...
