The combinatorial clock auction is becoming increasingly popular for large-scale spectrum awards and other uses, replacing more traditional ascending or clock auctions. We describe some surprising properties of the auction, including a wide range of ex post equilibria with demand expansion,...

An unprecedented “boom and bust” investment cycle occurred in the high-tech industries at the turn of the century, in particular in the telecommunications sector. Regulatory reforms and technological innovation fuelled expectations of robust growth in traffic, revenue and earnings....

I suggest explanations for the apparently puzzling bidding in the year 2000 British and German 3G telecom auctions. Relative-performance maximisation may have been important, but the outcome of the British auction seems to have been efficient. This paper bundles my comments on two papers...

Economic theory is often abused in practical policy-making. There is frequently excessive focus on sophisticated theory at the expense of elementary theory; too much economic knowledge can sometimes be a dangerous thing. Too little attention is paid to the wider economic context, and to the...

The design of the Federal Communications Commission spectrum license auction is a case study in the application of economic theory. Auction theory helped address policy questions such as whether an open auction or a sealed-bid auction should be used; whether the licenses should be auctioned...

We usually assume increases in supply, allocation by rationing, and exclusion of potential buyers will never raise prices. But all of these activities raise the expected price in an important set of cases when common-value assets are sold. Furthermore, when we make the assumptions needed to rule...

The most important issues in auction design are the traditional concerns of competition policy-preventing collusive, predatory, and entry deterring behaviour. Ascending and uniform-price auctions are particularly vulnerable to these problems (we discuss radiospectrum and football TV-rights...

The design of the FCC spectrum-license auction is a case study in the application of economic theory. Auction theory helped address policy questions such as: Should an open auction or a sealed-bid auction be used? Should the licenses be auctioned sequentially or simultaneously? Should the...

There were enormous differences in the revenues from the European ‘third generation’ (3G, or ‘MTS’) mobile-phone license auctions, from 20 Euros per capita in Switzerland to 650 Euros per capita in the UK, though the values of the licences sold were similar. Poor auction designs in some...
