In this paper I analyse a labour market where the wage is endogenously determined according to an Efficient Bargaining process between a firm and a labour union whose members are partitioned into two social groups: the old and the young. Furthermore, I exploit the Single-Mindedness theory, which...

How should we compare welfare across pension systems in presence of differential mortality? A commonly used standard utilitarian criterion implicitly favors the long-lived over the short-lived. We investigate under what conditions this ranking is reversed. We clearly distinguish between the...

This paper studies optimal insurance against idiosyncratic wage shocks in a life cycle model with intensive labor supply and endogenous retirement. When the fixed cost of work is increasing in wage, the optimal retirement wedge provides stronger incentives for delayed retirement with age....

The central purpose of this paper is to introduce a new political economy explanation to modern Social Security Systems. This approach is based on the Single-Mindedness Theory (SMT), which assumes that the more single-minded groups are able to exert a greater power of influence on Governments...

In this paper I will introduce a new political economy model, where there exists a competition amongst two political candidates, which aim to set a policy which enables them to win elections, max- imising the probability of winning. I will show that, if taxes neces- sary to repay the debt are...

This paper analyzes the dynamic politico-economic equilibrium of a model where repeated voting on social security and the evolution of household characteristics in general equilibrium are mutually affected over time. In particular, we incorporate within-cohort heterogeneity in a two-period...

Abstract We study optimal savings policies when there is a dual concern about undersaving for retirement and income inequality. Agents differ in present bias and earnings ability, both unobservable to a planner with paternalistic and redistributive motives. We characterize the solution to this...

This paper considers an overlapping-generations model with pay-as-you-go social security and retirement decision making by an old agent. In addition, the paper assumes that labor productivity depreciates. Under this setting, socially optimal allocations are examined. The first-best allocation is...

We study policy reforms aimed at overhauling retirement financing. We develop a novel approach by considering optimal reforms: policy reforms that minimize the cost for the government while respecting the distribution of welfare in the economy. Our model is an OLG model with life-cycle features...
