When firms undertake activities which are environmentally risky, the divergence between social and private incentives to exert safety care requires public intervention. This control occurs both through ex ante regulation and ex post legal investigation. We delineate the respective scopes of...

The renegotiation of regulatory contracts is known to prevent regulators from achieving the full commitment efficient outcome in dynamic contexts. However, assessing the cost of such renegotiation remains an open issue from an empirical viewpoint. To address this question, we fit a structural...

A risk averse agent gathers information on productivity shocks and produces accordingly on behalf of his principal. Information gathering is imperfect so that the agent has either complete or no knowledge at all of those shocks. The model allows for moral hazard in information gathering, private...

This Paper analyses the link between the internal organization of firms, their individual life cycle and the whole process of macroeconomic growth. We present a Schumpeterian growth model in which firms face dynamic agency costs. These agency costs are due to the formation of vertical collusions...

This paper analyzes whether the two tasks of building infrastructures which are socially useful and managing those assets should be bundled or not. When performances contracts can be written, both tasks should be performed altogether by the same firm when a better design of the infrastructure...

This Paper proposes a theory of the optimal organization of delegated expertise. For incentive purposes, a principal should reward an expert when their recommendation is confirmed either by the facts or by other experts’ recommendations. With a single expert, we show that the agency costs of...

We propose a theory of supervision with endogenous transaction costs. A principle delegates part of his authority to a supervisor who can acquire soft information about an agent's productivity. If the supervisor were risk-neutral, the principal would simply make the better informed supervisor...

This Paper analyses the impact of asymmetric information within countries on the pattern of international trade. We append to the standard 2×2 Heckscher-Ohlin model of a small economy a continuum of sectors producing intermediate non-tradable goods. Those goods are produced by monopolies having...
