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...

In a simple stochastic overlapping generation model, individuals work when young and retire when old, generations’ productivity is affected by a serially uncorrelated random shock, and fiat money and nominal public debt are the only storable assets. In this setting, we show that social...

The design of fully funded pension plans is affected by governance and incentive problems, as underlined by the experience of several countries. The analytic perspective of contract theory allows to detect the nature of such problems: pension-fund managers have strong incentives to manipulate...

The economic literature on PPPs has generally overlooked agency problems within private consortia. We provide a first contribution in this direction, relying on a simple incomplete contracts framework where a Builder and an Operator set up a Special Purpose Vehicle (SPV) to carry out a contract...

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...

In a simple model of network industry, where an upstream monopolist provides an essential input for downstream service supply, we analyze the competitive settings arising in the downstream market under alternative regulatory frameworks; we combine structural (i.e. vertical integration,...
