We experimentally examine the collusive properties of two commonly used auctions: the English auction (EN) and the first-price sealed-bid auction (FPSB). In theory, both tacit and overt collusion are always incentive compatible in EN while both can be incentive compatible in FPSB if the auction...

We test the Average Credible Deviation Criterion (ACDC), a stability measure and refinement for cheap talk equilibria introduced in De Groot Ruiz, Offerman & Onderstal (2011b). ACDC has been shown to be predictive under general conditions and to organize data well in previous experiments meant...

Currently no refinement exists that successfully selects equilibria across a wider range of Cheap Talk games. We propose a generalization of refinements based on credible deviations, such as neologism proofness and announcement proofness. According to our Average Credible Deviation Criterion...

We experimentally examine the effectiveness of antitrust policies against bidding rings in theEnglish auction (EN) and the first-price sealed-bid auction (FP). We consider both traditionalantitrust policy (without a leniency program) and modern antitrust policy (with a leniencyprogram). In EN,...

In the past, many refinements have been proposed to select equilibria in cheap talk games. Usually, these refinements were motivated by a discussion of how rational agents would reason in some particular cheap talk games. In this paper, we propose a new refinement and stability measure that is...
