Measurement and management of information asymmetry prior to a public offer.

Summary France is characterized by a particularly active market for public offers. This market is essentially composed of offers to strengthen control and to close the capital. This specificity is not neutral in terms of information. This has led us to question the effects of information asymmetry on the bidding process and the latitude of the bidder to manage it. The first part of this research is devoted to two reviews of the literature and to the statement of our hypotheses. The first reviews the literature on the motivations of offers and highlights their plurality. The second part focuses on the modelings that have emphasized the informational variable as well as the pre-bid buying strategies.
