Several approaches for subset recovery and improved forecasting accuracy have been proposed and studied. One way is to apply a regularization strategy and solve the model selection task as a continuous optimization problem. One of the most popular approaches in this research field is given by...

This paper explores the introduction of collective risk-reallocation elements in defined contribution pension contracts. We consider status-contingent, age-contingent and asset-contingent arrangements to reallocate risk among participants. Eliminating asset market risk for the retired raises...

In this paper, we present an innovative electricity spot price model, wherein the prices explicitly depend on the realized wind power production. The proposed arithmetic multi-factor approach captures numerous stylized facts of empirical spot price behavior like seasonal variations,...

In this paper we develop a dynamic structural life-cycle model of labor supply behavior which fully accounts for the effect of income tax and transfers on labor supply incentives. Additionally, the model recognizes the demand side driven rationing risk that might prevent individuals from...
