Recent reforms of the Italian social security system (Amato-Dini reforms) aimed at reversing the upward trend in Government pension spending. The main provisions of these reforms are: i) the adoption of a (unfunded) defined contribution system as a basis for computing pensions benefits, ii) a...

This paper analyzes a recent ballot in which two virtually identical popular initiatives, both demanding a decrease in the legal age of retirement in Switzerland, led to differences in approval rates of nearly seven percentage points. Based on this unique natural experiment, the existence of...

Why does the largest US welfare programme select its recipients by their age, rather than by their earnings or wealth? In a dynamic efficient overlapping generation economy with earnings heterogeneity, we analyze a welfare system composed of a within-cohort redistribution scheme and an unfunded...

During the period from 1880 to 1950 publicly managed retirement security programs became an important part of the social fabric in most advanced economies. In this paper we study the social, demographic and economic origins of social security. We describe a model economy in which demographics,...

Generous early retirement provisions account for a large proportion of the drop in the labour force participation of elderly workers. The aim of this paper is to provide a political-economic explanation of the wide spread adoption of early retirement. We suggest that the political support for...

It is often argued that the observed trend towards early retirement is due mainly to the implicit tax imposed on continued activity of elderly workers. We study the relevance of such a distortion in a political economy model with endogenous age of retirement. The setting is a two-period...

We introduce tax contracts and examine how they affect government formation and welfare of voters in a democracy with proportional elections. A tax contract specifies a range of tax rates a party is committed to if in government. We develop a new model of party competition in which parties...

In this paper we examine the impact of tax contracts, a novel instrument, on elections, policies, and welfare. We consider a political game in which three parties compete to form the government and voters may behave strategically. Parties have policy preferences about the level of public-good...

In a stochastic two-period OLG model, featuring an aggregate shock to the economy, ex-ante optimality requires intergenerational risk sharing. We compare the level of time-consistent intergenerational risk sharing chosen by a social planner and by office seeking politicians. In the political...

Why do voters support PAYG social security systems? Browning (1975) suggested that for a majority of voters, who consider past contributions as a sunk cost, unfunded systems may represent a better investment than alternative assets, such as mutual or pension funds. I quantify the relevance of...
