The recent crisis has shown that banks in distress can often expect to benefit from (implicit) government guarantees. This paper analyzes a panel of 781 banks from 90 countries to test whether the expectation of individual and systemic government support induces moral hazard. It shows that banks...

We develop a theoretical framework to study illicit drugs markets and we estimate it using data on purchases of crack cocaine. Buyers are searching for high-quality drugs, but they determine drugs' quality (i.e., their purity) only after consuming them. Hence, sellers can rip off first-time...

A principal should hire one agent to perform two sequential tasks when the tasks are conflicting (i.e., a first-stage success makes second-stage effort less effective), while she should hire two different agents when the tasks are synergistic.

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...

Following the financial crisis of 2008/9, there has been renewed interest in what Greenwald and Stiglitz dubbed ‘pecuniary externalities’. Two that affect borrowers and lenders balance sheets in pro-cyclical fashion are described, along with measures that might help curb their destabilising...

We study dynamic moral hazard, with symmetric ex ante uncertainty and learning. Unlike Holmstrom's career concerns model, uncertainty pertains to the difficulty of the job rather than the general talent of the agent, so that contracts are required to provide incentives. Since effort is privately...

This paper analyzes the impact of labor market competition and skill-biased technical change on the structure of compensation. The model combines multitasking and screening, embedded into a Hotelling-like framework. Competition for the most talented workers leads to an escalating reliance on...

Some existing welfare programs (“work-first”) require participants to work in exchange for benefits. Others (“job search-first”) emphasize private job-search and provide assistance in finding and retaining a durable employment. This paper studies the optimal design of welfare programs...

Many of the world’s developed economies have introduced, or are planning to introduce, bank bail-in regimes. Both the planned EU resolution regime and the European Stability Mechanism Treaty involve the participation of bank creditors in bearing the costs of bank recapitalization via the...

Debt mutualisation through Eurobonds has been proposed as a solution to the Euro crisis. Although this proposal found some support, it also attracted strong criticisms as it risks raising the spreads for strong countries, diluting legacy debt and promoting moral hazard by weak countries. Because...
