We characterize how public insurance schemes are constrained by hidden financial transactions. When non-exclusive private insurance entails increasing unit transaction costs, public transfers are only partly offset by hidden private transactions, and can influence consumption allocation. We show...

Es wird untersucht, wie ein System privater Versicherungen gegen das Risiko der Arbeitslosigkeit beschaffen sein sollte. Zu dem Zweck wird ein Trennsystem vorgeschlagen, das Arbeitnehmern und Arbeitgebern gleichermaßen Anreize zur Verminderung von Arbeitslosigkeit gibt. Für die Arbeitnehmer...

Moral hazard models with hidden saving decisions are useful to study such diverse problems as unemployment insurance, income taxation, executive compensation, or human capital policies. How can we solve such models? In general, this is very difficult. Under the conditions derived in this paper,...

This paper examines the first order approach to moral hazard problems in which the agent can secretly save and borrow. The paper shows that hidden saving constrains the concavity of the agent's problem even for CARA utility and additively separable effort disutility in an important way:...

We analyze a dynamic moral hazard setting, in which agents can borrow and lend and their decisions about effort, consumption and savings are private information. In contrast with previous findings, we show that as long as agents do not have perfect control over publicly observable outcomes, the...

It is well known that modern governments are unwilling to use poll taxes because it corresponds to political suicide. Still, poll taxes are allegedly the most efficient form of taxation. Building on Eaton and Rosen (1980) and Peck (1989), the goal of this paper is to show a case where an excise...
