Collusion in uniform-price auctions: experimental evidence and implication for treasury auctions

We provide experimental evidence that nonbinding preplay communicationbetween bidders in auctions of shares facilitates the adoptionof equilibrium strategies: collusive strategies in uniform-priceauctions, and the unique equilibrium in undominated strategiesin discriminatory auctions. When communication between biddersis introduced, clearing prices and auctioneer profits in uniform-priceauctions fall below those observed in discriminatory auctions.This evidence suggests that uniform-price auctions of Treasurysecurities may result in lower revenues than the currently employeddiscriminatory procedure.     

Further evidence on the international business cycle and the ERM: is there a European business cycle?

Successful exchange rate regimes impose policy disciplines thatare likely to lead to conformity in the business cycles of theparticipating countries. This conjecture is borne out in thepaper by the evidence in it that the business cycle affiliationof ERM member countries has shifted from the United States toGermany since the formation of the ERM. This effect is bolsteredby the growing links in trade between the EU countries. TheUnited Kingdom is conspicuous among the latter in that its businesscycle affiliation did not change in the period covered by thestudy.     

New Goods and the Transition to a New Economy

The U.S. went through a remarkable structural transformation between 1800 and 2000. A precipitous decline in the importance of agricultural goods in the economy was matched by the rapid ascent of a plethora of new non-agricultural goods and services. A competitive model is presented here where consumption evolves along the extensive margin. This lessens the need to rely on satiation points, subsistence levels of consumption, and the like to explain agriculture’s demise. The analysis suggests that between 1800 and 2000 economic welfare grew by at least 1.5% a year, and may be as much as 10% annually, the exact number depending upon the metric preferred.The authors thank (Richard) Ming Hon Suen and two referees for comments.
