We consider optimal stopping problems in uncertain environments for an agent assessing utility by virtue of dynamic variational preferences or, equivalently, assessing risk by dynamic convex risk measures. The solution is achieved by generalizing the approach in terms of multiple priors...

In this paper we investigate the possibilities of Pareto-improving reforms of a pay-as-you-go (PAYG) pension system in a framework of endogenous growth. Belan et al. (1996) propose a transition of a PAYG system to a system of savings--subsidization. We follow this approach and prove that a...

The interaction of social security (based on the two pillars unemployment insurance and public pension system), unemployment, and economic growth is considered in an overlapping generations model with endogenous growth and efficiency wages. The impact of each worker's and employer's social...

In a general setting of private information, the possibility (impossibility) theorem is said to be valid, if a balanced and ex post efficient mechanism exists (does not exist) which agents voluntarily participate at. Possibility and impossibility results are called robust if they hold for all...

Firms face the problem of choosing a debt maturity structure when financing an investment project. In addition, they have to decide which financing source to take. The aim of this article is firstly to give an explanation for the differing maturity choices by firms. As is shown below, the...
