The issue of whether unemployment benefits should increase or decrease over the unemployment spell is analyzed in an analytically tractable model allowing moral hazard, adverse selection and hidden savings. Analytical results show that when the search productivity of unemployed is constant over...

We propose a model based on competitive markets in order to analyse an economy with several principals and agents. We model the principal-agent economy as a two-sided matching game and characterise the set of stable outcomes of this principal-agent matching market. A simple mechanism to...

Recruitment is often delegated to senior employees. Delegated recruitment, however, is vulnerable to moral hazard because senior employees may avoid recruiting the best candidates who could threaten their future seniority. We find that seniors will not deliberately choose bad candidates if the...

We completely characterize the set of second-best optimal "menus"of student-loan contracts in a simple economy with risky labour-market outcomes, adverse selection, moral hazard and risk aversion. The model combines structured student loans and an elementary optimal income-tax problem à la...

We study an important mechanism underlying employee referrals into informal low skilled jobs in developing countries. Employers can exploit social preferences between employee referees and potential workers to improve discipline. The profitability of using referrals increases with referee stakes...

This paper looks at a specific type of moral hazard that arises in the interplay between two large public insurance systems in Sweden, namely the sickness insurance (SI) and the unemployment insurance (UI). Moral hazard can arise from the benefit size structure as for some unemployed persons,...

This paper considers a panel duration model that has a proportional hazards specification with fixed effects. The paper shows how to estimate the baseline and integrated baseline hazard functions without assuming that they belong to known, finitedimensional families of functions. Existing...

We analyze individuals with heterogeneous time-inconsistent preferences that consume sin goods and make a savings decision. A government may tax the sin good and provide mandatory health insurance. Due to time-inconsistency, the individual sin good and savings choices in ict internalities. Due...

Influenza imposes substantial costs worldwide in terms of human lives and productivity losses. Vaccination could be a cost-effective way to reduce these costs for firms and public health institutions, but low take-up rates, particularly of working adults, and vaccination unintendingly causing...
