In both a re-matching condition and a fixed-matching condition, we observe that biddings rings are more stable in the English auction than in the first-price sealed-bid auction. In both conditions, the first-price sealed-bid auction dominates the English auction in terms of average revenue and the revenue spread. The English auction outperforms the first-price sealed-bid auction in terms of efficiency.
