Pratique de l’échocardiographie : place de la délégation de compétence

We propose a general formal structure for symmetric information delegation games that encompasses many existing economic applications in the fields of oligopoly theory, strategic trade policy and international political economy. We prove that all individually rational allocations are implementable in delegation games with non-separable utility. Secondly, we prove that the results are robust to the introduction of secret side-contracts, provided that the side transfer technology implies a dead-weight loss increasing in the size of the transfer.
