Consider a group of individuals whose behavior is subject to moral hazard, and suppose that providing them with incentives requires a monitor to detect deviations. What about the monitor's deviations? I study mediated contracts and find that the monitor's deviations are effectively irrelevant. Hence, nobody needs to monitor the monitor. I also characterize(More)
This Letter reports results from the MINOS experiment based on its initial exposure to neutrinos from the Fermilab NuMI beam. The rates and energy spectra of charged current nu(mu) interactions are compared in two detectors located along the beam axis at distances of 1 and 735 km. With 1.27 x 10(20) 120 GeV protons incident on the NuMI target, 215 events(More)
An aggregate game is a normal-form game with the property that each player's payoff is a function only of his own strategy and an aggregate function of the strategy profile of all players. Aggregate games possess a set of purely algebraic properties that can often provide simple characterizations of equilibrium aggregates without first requiring that one(More)
The velocity of a 3 GeV neutrino beam is measured by comparing detection times at the near and far detectors of the MINOS experiment, separated by 734 km. A total of 473 far detector neutrino events was used to measure …v ÿ c†=c ˆ 5:1 2:9 10 ÿ5 (at 68% C.L.). By correlating the measured energies of 258 charged-current neutrino events to their arrival times(More)
Phosphorylation sites in the mouse oestrogen receptor, expressed in COS-1 cells in the presence of 17 beta-oestradiol, have been mapped by solid phase microsequencing. The receptor was first radio-labelled with [32P]orthophosphate and a number of 3H- or 14C-labelled amino acids, immunopurified and then tryptic peptides were separated by thin layer(More)
A speaker attempts to persuade a listener to accept a request by presenting evidence. A persuasion rule specifies what evidence is persuasive. This paper compares static and dynamic rules. We present a single linear program (i) whose solution corresponds to the listener's optimal dynamic rule and (ii) whose solution with additional integer constraints(More)
Consider a strategic environment subject to moral hazard and adverse selection across multiple stages, with rich communication protocols. In this paper, we prove that for any allocation, there exist linear transfers to make it incentive compatible if and only if every undetectable deviation from honesty and obedience is unprofitable when the transfers equal(More)
We found 140 neutrino-induced muons in 854.24 live days in the MINOS far detector, which has an acceptance for neutrino-induced muons of 6:91 10 6 cm 2 sr. We looked for evidence of neutrino disappearance in this data set by computing the ratio of the number of low momentum muons to the sum of the number of high momentum and unknown momentum muons for both(More)
The complete 5.4 kton MINOS far detector has been taking data since the beginning of August 2003 at a depth of 2070 meters water-equivalent in the Soudan mine, Minnesota. This paper presents the first MINOS observations of and charged-current atmospheric neutrino interactions based on an exposure of 418 days. The ratio of upward-to downward-going events in(More)
