Recently, the combinatorial clock auction has become more and more common in the auctioning of telecommunication licenses. Although the auction design is complex, the promise is that bidding becomes simple - truthtelling is "close to optimal". We show that this claim is too strong. The auction...

We test for the distributional effects of regulation and entry in the mobile telecommunications sector in a highly unequal country, South Africa. Using six waves of a consumer survey of over 134,000 individuals between 2009-2014, we estimate a discrete-choice model allowing for...

In this paper I review the Dutch UMTS-auction that took place in the summer of 2000 and which, in contrast to the UK and German auctions, was generally considered to be a major flop. I analyse the policy process leading to the auction as well as the bidding behaviour in the auction, and provide...

This paper considers bidder behaviour in the United Kingdom s UMTS spectrum auction. Evidence is reviewed which shows that some bidders in this auction did not bid straightforwardly in accordance with fixed valuations of the licenses. We go on to consider more speculative hypotheses about...

We evaluate the welfare effects of the Roam-Like-At-Home regulation, which drastically re-duced the price of accessing the mobile internet for EU residents when traveling abroad in the European Economic Area. Estimates from individual-level usage data suggest that consumer surplus increased by...

We empirically assess the impact of the EU roaming regulation on mobile operators' average revenues per user (ARPU) and retail prices. Using a differences-in-difference approach, hedonic price regressions and detailed operator and plan-level data we find that the regulation decreased mobile...

The roam-like-at-home regulation (RLAH) eliminated all mobile roaming surcharges to Eu-ropean consumers travelling within the European Economic Area (EEA). We measure the causal impact of the regulation on EEA roaming traffic, using the Rest of the World as a control group. We find large and...
