This paper develops a methodology for characterizing expected revenue from auctions when bidders' types come from an arbitrary distribution. In particular, types may be multidimensional, and there may be mass points in the distribution. One application extends existing revenue equivalence...

A crucial assumption in the optimal auction literature is that each bidder's valuation is known to be drawn from a unique distribution. In this paper we study the optimal auction problem allowing for ambiguity about the distribution of valuations. Agents may be ambiguity averse (modeled using...

It is well-known that the ability of the Vickrey-Clarke-Groves (VCG) mechanism to implement efficient outcomes for private value choice problems does not extend to interdependent value problems. When an agent's type affects other agents' utilities, it may not be incentive compatible for him to...

This paper provides the first empirical examination of the microstructure of the euro money market, using tick data from brokers located in 6 countries. Special emphasis is put on the institutional environment (monetary policy decisions and their implementation, payment systems and private...

We study bidder bahavior and performance in 53 main refinancing operations (repo auctions) of the European Central Bank (ECB). The data set starts with the first auctions after the ECB changed from fixed rate tenders to variable rate tenders. We find that private information and the winnner's...

This paper employs individual bidding data to analyze the empirical performance of the longer term re?nancing operations (LTROs) of the European Central Bank (ECB). We investigate how banks’ bidding behavior is related to a series of exogenous variables such as collateral costs, interest rate...

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...

We study the prices that individual banks pay for liquidity (captured by borrowing rates in repos with the central bank and benchmarked by the overnight index swap) as a function of market conditions and bank characteristics. These prices depend in particular on the distribution of liquidity...

Recent research suggests that auction winners sometimes fall prey to a "bidder's curse", paying more for an item at auction than they would have paid at a posted price. One explanation for this phenomenon is that bidders are inattentive to posted prices. We develop a model in which bidders'...

Auctions are the allocation-mechanisms of choice whenever goods and information in markets are scarce. Therefore, understanding how information affects welfare and revenues in these markets is of fundamental interest. We introduce new statistical concepts, k- and k-m-dispersion, for...
