We use a unique firm-level panel data set of multinational parents and their foreign affiliates to analyze whether profits are shared across borders within multinational firms. Using both fixed-effects and generalized method-of-moments estimators, affiliate wage levels are estimated to respond to both affiliate and parent profitability.

CONTRIBUTIONS TO ORDER STATISTICS by

Three different problems in order statistics are considered in this dissertation. The first problem deals with the recurrence relations between moments and other functions of order statistics. It is shown that recurrence relations valid for independent and identically distributed random variables continue to hold for exchangeable variables. In the second problem a method, based upon orthogonal ...

W. Stephen Wilson’s Contributions to Homotopy Theory

This paper is a survey of Steve’s work on BP and periodic cohomology theories. It was presented as a talk given in March 2007 at a conference celebrating Steve’s 60th birthday. 1. Cohomology of Ω-spectra and Hopf rings Steve Wilson’s thesis, directed in 1972 by Frank Peterson, started unstable BP theory as we know it. Part 1 of his thesis appeared as [13], where he shows that the spaces in the ...
