Is there a role for debt beyond curing overaccumulation of capital? Does dynamic efficiency and the infeasibility of debt Ponzi schemes eliminate any Pareto-improving role for a government in a competitive economy with complete markets? Is there an optimal maturity structure of public debt?...

This paper studies the income of Swedish households belonging to the baby boom generation, i.e. those born in the 1940-50. An international comparison as well as an historical presentation of income patterns is given. However, the main purpose is to generate the future income of the baby boom...

Das Urteil des Bundesverfassungsgerichtes zur Höhe der Regelsätze in der Grundsicherung hat in Deutschland eine breite öffentliche Diskussion über Arbeitsanreize im Niedriglohnbereich ausgelöst. Der BDA und das IW haben in diesem Zusammenhang einen Vorschlag in die Diskussion eingebracht,...

Ökonomische Effizienz und soziale Gerechtigkeit stehen nicht im Widerspruch zueinander. Workfare ist sozial gerecht. Durch das Prinzip von Leistung und Gegenleistung wird dafür gesorgt, dass sich die Inanspruchnahme von Leistungen der Grundsicherung auf diejenigen beschränkt, die tatsächlich...

Rothschild and Stiglitz (1976) show that there need not exist a competitive equilibrium in markets with adverse selection. Building on their framework we demonstrate that externalities between agents − an agent's utility upon accepting a contract depends on the average type attracted by the...

We consider a labor market where the competitive search equilibrium is inefficient due to asymmetrical information. At the time when firms commit to specific hiring costs, workers hold private information on their intention of entering into retirement before the termination of the contract. When...

We characterize optimal incentive contracts in a moral hazard framework extended in two directions. First, after effort provision, the agent is free to leave and pursue some ex-post outside option. Second, the value of this outside option is increasing in effort, and hence endogenous. Optimal...

Incentives often fail in inducing economic agents to engage in a desirable activity; implementability is restricted. What restricts implementability? When does re-organization help to overcome this restriction? This paper shows that any restriction of implementability is caused by an...

This study models producer protection legislation that would grant growers the right to claim damages (PPLD) if their contracts are prematurely terminated. In the absence of contracting frictions that prevent contractors from redesigning contracts to accommodate exogenous policy changes, PPLD...

Several empirical studies have challenged tournament theory by pointing out that (1) there is considerable pay variation within hierarchy levels, (2) promotion premiums only in part explain hierarchical wage differences and (3) external recruitment is observable on nearly any hierarchy level. We...
