The gains in life expectancy are expected to double the dependency ratio and increase population by 10% in Switzerland until 2050. To quantify the effects on pensions, taxes and social contributions, we use an overlapping generations model with five margins of labor supply: labor market...

The paper proposes an intertemporal equilibrium model with monopolistic competition and free entry to explain the nexus between business formation and medium run growth. An investment externality is identified that results in underaccumulation of capital in the decentralized market equilibrium...

The paper reviews an algorithm for the iterative solution of rational expectations models. It shows in detail how general equilibrium models with perfect foresight and intertemporally optimizing behavior must be set up to be solved numerically with the algorithm. Three examples of intertemporal...
