The empirical analysis shows that this cannot be viewed as a success of the issuing technique or as the result of the discretion enjoyed by some Treasuries in the stop-out price setting procedure, but rather as a consequence of the Treasuries bundling the securities auctioned with a number of commodities, such as the syndication rights. Since the overpricing may harm the long-run competitiveness of Treasury auctions by driving the smaller primary dealers out of the primary market, I suggest discontinuing the bundling or exploring alternative auction mechanisms such as the clock auctions, and in particular those which put up different items simultaneously.
