In a model with heterogeneous workers and both intensive and extensive margins of employment, we consider two systems of redistribution: a universal basic income, and a categorical unemployment benefit. Well-being depends on own-consumption relative to average employed workers' consumption, and...

We compare two systems of income redistribution: unemployment benefits (UB) and basic income (BI). First, for a simple utility function, with both intensive and extensive margins, the unemployed are likely better off with pure BI than pure UB, regardless of labour supply elasticity and wage...

Should two-band income taxes be progressive given a general income distribution? We provide a negative answer under utilitarian and max-min welfare functions. While this result clarifies some ambiguities in the literature, it does not rule out progressive taxes in general. If we maximize total...

Informal long-term relationships and mutual confidence play a crucial role in modern economies in at least two dimensions. First, the performance of firms is strongly affected by their capacity to solve organizational questions effectively and this capacity is apparently strongly related to...

This paper develops a simple general equilibrium model which establishes a link between the patience of economic agents and the well-being of nations. We show that firms in long-term oriented countries can mitigate hold-up inefficiencies by engaging with their suppliers in relational contracting...

This paper studies a partial-contracting model where an agent may provide effort to increase a project's scope before some later decisions have to be taken. Consistent with existing empirical evidence, we find a positive relationship between exogenous risk and delegation. That is, we show that...

"Implicit Contracts, incentive compatibility, and involuntary unemployment" (MacLeod and Malcomson, 1989) remains our most highly cited work. We briefly review the development of this paper and of our subsequent related work, and conclude with reflections on the future of relational contract...

The 'ratchet effect' refers to a situation where a principal uses private information that is revealed by an agent's early actions to the agent's later disadvantage, in a context where binding multi-period contracts are not enforceable. In a simple, context-rich environment, we experimentally...

Using a new survey of European households, we study how exogenous variation in the macroeconomic uncertainty perceived by households affects their spending decisions. We use randomized information treatments that provide different types of information about the first and/or second moments of...
