This paper estimates Taylor rules featuring instabilities in policy parameters, switches in policy shocks' volatility, and time-varying trend inflation using post-WWII U.S. data. The model embedding the stochastic target performs better in terms of data-fit and identification of the changes in...

This paper estimates regime-switching monetary policy rules featuring trend inflation using post-WWII US data. We find evidence in favour of regime shifts and time-variation of the inflation target. We also find a drop in the inflation gap persistence when entering the Great Moderation sample....

Governments redistribute by means of taxes, transfers, and public services. Relying on three sufficient statistics, we characterize the conditions under which nonlinear income taxation is optimally combined with input public provision in two-class and multi-class economies, where individual...

This paper characterizes the optimal tax and expenditure policies in economies where households’ unobservable gross earnings depend on exogenous (or inherited) capabilities and input investments. In a two-class economy, optimal redistribution relies on non-linear income taxation and input...

In this paper we investigate how tightening fiscal constraints (e.g., through intergovernmental transfer cuts) can lead local governments to postpone investments’ payments. We first provide a simple model showing how local governments can use arrears to relax their short-run financial...

We analyze the optimality of alternative mechanisms of public provision of private goods affecting the productive capacity of households (e.g. education, health-care) rather than directly their welfare. Opting out mechanisms - often considered a tool to focus social expenditure - are proven to...

The relationship between fiscal and financial euro area indicators and sovereign yield spreads has changed after the start of the financial crisis. Increased financial volatility has magnified the impact of fiscal conditions as drivers of sovereign risk, has widened the set of macroeconomic...
