- Abstract
- This paper develops a small-scale DSGE model which embeds a demographic structure within a monetary policy framework. We extend the tractable, though non-monetary overlapping-generations model of Gertler (1999) and present a small synthesis model which combines the set-up of Gertler with a New-Keynesian structure, implying that the short-run dynamics related to monetary policy are similar to the paradigm summarized in Woodford (2003). In sum, the model offers a New-Keynesian platform which can be used to investigate in a closed economy set-up the response of macroeconomic variables to demographic shocks, similar to technology, government spending or monetary policy shocks. Empirically, we use a calibrated version of the model to discuss a number of macroeconomic scenarios for the euro area with a horizon of around 20 years. The main finding is that demographic changes, while contributing slowly over time to a decline in the equilibrium interest rate, are not visible enough within the time horizon relevant for monetary policy-making to require monetary policy reactions.

- Abstract
- In this paper we use the Generalized Taylor Economy (GTE) framework in which there are many sectors with overlapping contracts of different lengths to analyze the design of monetary policy. We derive a utility based objective function of a central bank for this economy and use it to evaluate the performance of alternative simple rules. We find that a simple rule that targets an index that gives more weight to the sectors which have longer contracts and are more important in the aggregate index yields a welfare outcome nearly identical to the optimal policy. However, we find that potential gains in targeting sector specific inflation rates rather than the aggregate inflation rate is very sensitive to the shape of the distribution. We show that except for the cases where prices/wages are reoptimized very frequently, the performance of the sectoral rule can be closely approximated by a simple rule that targets aggregate inflation.

- Abstract
- 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 contract lengths and for different types of price setting. In particular, we find that allowing for a distribution of contract lengths can yield a more plausible explanation of inflation persistence than indexation.

- Abstract
- In this paper we develop the Generalized Taylor Economy (GTE) in which there are many sectors with overlapping contracts of different lengths. In economies with the same average contract length, monetary shocks will be more persistent when longer contracts are present. We are able to solve the puzzle of why Calvo contracts appear to be more persistent than simple Taylor contracts: it arises because of the distribution of contract lengths. When we choose a GTE with the same distribution of completed contract lengths as the Calvo, the economies behave in a similar manner.
