Using laboratory experiments, we compare the stability of bidding rings in the English auction and the first-price sealed-bid auction in a heterogeneous-value setting. In both a re-matching condition and a fixed-matching condition, we observe that biddings rings are more stable in the English...

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,...

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...

In a field experiment, we study the revenue-generating properties of premium auctions. In a premium auction, the runner-up obtains a premium for driving up the price paid by the winner. Previous research, both theoretical and in the lab, has shown that the relative performance of premium...
