In the past, the Simultaneous Multi-Round Auction (SMRA) has been the de facto standard for spectrum sales worldwide. Recently, the Combinatorial Clock Auction (CCA) has been used as an alternative to the SMRA in a number of countries promising strong incentives for truthful bidding and high efficiency as a result. This thesis uses lab experiments to analyze the performance of CCA in comparison to SMRA and examines bidding behavior. We do not find a significant superior performance of CCA in terms of efficiency and revenue. Bidders in the CCA submitted only bids for a fraction of all possible bundles and used heuristics to select bundles. In addition, we leveraged competitions to confirm the findings and support the external validity of the results.
