We study the ex-ante budget devoted by a Political Principal to a Competition Authority in charge of collecting evidence on the Industry's behavior. The Industry can capture both the Principal (lobbying) for a reduced budget, and the Authority (side-contracting) so as to avoid fines. Authority's...

We consider multiple-principal multiple-agent games of incomplete information. In this context, we identify a class of direct and incentive compatible mechanisms: each principal privately recommends to each agent to reveal her private information to the other principals, and each agent behaves...

We consider an exchange economy in which a seller can trade an endowment of a divisible good whose quality she privately knows. Buyers compete in menus of non-exclusive contracts, so that the seller may choose to trade with several buyers. In this context, we show that an equilibrium always...

In this paper, we focus on the determinants of the relationship between aid and corruption. We propose a static principal-agent model where a donor faces the problem of giving aid to a recipient country in which the phenomenon of corruption is widely spread. We distinguish among two different...

We study competing-mechanism games under exclusive competition: principals first simultaneously post mechanisms, then agents simultaneously choose to participate and communicate with at most one principal. In this setting, which is common to competing-auction and competitive-search applications,...

We study games in which several principals design mechanisms in the presence of privately informed agents. Competition is exclusive: each type of each agent can participate with at most one principal and meaningfully communicate only with him. Economic models of exclusive competition restrict...

We empirically investigate the effect of oversight on contract outcomes in public procurement. In particular, we stress a distinction between public and private oversight: the former is a set of bureaucratic checks enacted by contracting offices, while the latter is carried out by private...

We study a capital market in which multiple lenders sequentially attempt at financing a single borrower under moral hazard. We show that restricting lenders to post take-it-or-leave-it offers involves a severe loss of generality: none of the equilibrium outcomes arising in this scenario survives...

This paper studies government funding for scientific research. Funds must be distributed among different research institutions and allocated between basic and applied research. Informational constraints prevent less productive institutions to be given any government funding. In order to...

We consider multiple-principal multiple-agent models of moral hazard: Principals compete through mechanisms in the presence of agents who take unobservable actions. In this context, we provide a rationale for restricting principals to make use of simple mechanisms, which correspond to direct...
