In multi-object auction models with unitary demand agents, if agents utility functions satisfy quasi-linearity, three auction formats, sealed-bid auction, exact ascending auction, and approximate ascending auction, are known to identify the minimum price equilibrium (MPE), and exhibit elegant...

We analyse how the market design influences the bidding behaviour in multi-unit auctions, such as wholesale electricity markets. It is shown that competition improves for increased market transparency and we identify circumstances where the auctioneer prefers uniform to discriminatory pricing....

The tender spread, i.e. the difference between the effective price for money in the ECB’s main refinancing operations and the prevailing policy rate, is one of the main determinants behind the evolution of the EONIA with respect to the ECB’s operational target. This study assesses the...

How willing are individual primary dealers to alter their offered yields in central bank quantitative easing auctions of government bonds in order to sell an additional share of the outstanding amount of a bond to the central bank? This question is of great importance for a central bank's...

I develop a framework to study common situations, in which substitute goods are sold in separate, good-specific multi-unit (pay-as-bid) auctions. I characterize bidding behavior and investigate auction design features that could increase revenues. The setting I develop gives rise to an...

The tender spread, i.e. the difference between the effective price for money in the ECB's main refinancing operations and the prevailing policy rate, is one of the main determinants behind the evolution of the EONIA with respect to the ECB's operational target. This study assesses the reasons...

We analyze a divisible good uniform‐price auction that features two groups, each with a finite number of identical bidders, who compete in demand schedules. In the linear‐quadratic‐normal framework, this paper presents conditions under which the unique equilibrium in linear demands exists...

The Bank of Spain uses a unique auction format to sell government bonds, which can be seen as a hybrid of a uniform and a discriminatory auction. For winning bids above the average winning bid, buyers are charged the average winning bid, otherwise they pay their respective bids. We report on an...
