This paper studies pension design from a risk management point of view using a lexicographic loss aversion model. Interest in this model stems from the fact that it explains income expansion paths of equity and total savings particularly well. I find that all income groups are likely to benefit...

We study the properties of generalized stochastic gradient (GSG) learning in forward-looking models. We examine how the conditions for stability of standard stochastic gradient (SG) learning both differ from and are related to E-stability, which governs stability under least squares learning. SG...

Many countries face the problem of how to reform social security systems to cope with increasing life expectancy. This raises questions concerning both distribution and risk sharing across generations. These issues are addressed within an OLG model with stochastic life expectancy across...

We examine a stark setting in which security or protection can be provided by self-governing groups or by for-profit entrepreneurs (kings, kleptocrats, or mafia dons). Though selfgovernance is best for the population, it faces problems of long-term viability. Typically, in providing security the...

Transition patterns from school to work differ considerably across OECD countries. Some countries exhibit high youth unemployment rates, which can be considered an indicator of the difficulty facing young people trying to integrate into the labor market. At the same time, education is a...

Conventional wisdom has it that policy innovation is better promoted in a federal rather than in a unitary system. Recent research, however, has provided theoretical evidence to the contrary: a multi-jurisdictional system is characterized - due to the existence of a horizontal information...

In this paper, we introduce the fairness approach to efficiency wages into a standard model of international fragmentation. This gives us a theoretical framework in which wage inequality and unemployment rates are co-determined and therefore the public concern can be addressed that international...

We investigate the implications of product market imperfections on profit sharing, wage negotiation and equilibrium unemployment. The optimal profit share, which the firms use as a wage-moderating commitment device, is below the bargaining power of the trade union. Intensified product market...

This paper investigates the role of discount rate heterogeneity for wealth inequality. The key idea is to infer the distribution of preference parameters from the observed age profile of wealth inequality. The contribution of preference heterogeneity to wealth inequality can then be measured...
