Auctions with Almost Homogeneous Bidders
Full text linkWe deviate from the symmetric case of the independent private value model by allowing the bidders’ value distributions, which depend on parameters, to be slightly different. We show that previous results about the equality to the first-order in the parameters between revenues from the second-price auction and other auction mechanisms follow from the joint differentiability of the equilibria with respect to the parameters. We prove this differentiability for the first-price auction and obtain general formulas for the different first-order effects. From our results about the first-price auction, we analytically generate examples with continuous distributions where a stochastic improvement to a bidder’s value distribution reduces his equilibrium payoff. In another application, we show that, starting from competition among cartels of equal sizes, allowing in a small number of members from other cartels can be profitable only if the members or the synergies between them are strong enough.Independent private value model; auctions; asymmetry; first-price auction, second-price auction; differentiability; revenue equivalence theorem

A Study and Analysis of L. A. Lebrun\ue2s Oboe Concerto No.1 in D Minor
No full textLudwig August Lebrun (1752-1790), a German oboist and composer, is well known as an outstanding musician in the Mannheim School. He composed manycompositions for oboe and chamber music in his lifetime.This Oboe Concerto in D Minor, No.1 was written in the middle of 1770s, and Lebrun also performed this piece on his European concert tour.
There are three movements in Oboe Concerto in D Minor, No.1. The first movement is in sonata-concerto form withspirit. The second movement is in ternary formwhich islyrical melodies. The third movement is in rondo form; it is very lively.
This research is divided into four chapters. The first chapter mainly focuses on the composer and his life. The second chapter is about the background of this compositionand the musical style of Mannheim school. The third chapter is an analysis of this concerto. Finally, the fourth chapter is comparison of different versions of interpretations, especially about the articulation

Uniqueness of the Equilibrium in First-Price Auctions
Full text linkIf the value cumulative distribution functions are log-concave at the highest lower extremity of their supports, a simple geometric argument establishes the uniqueness of the equilibrium of the first-price auction in the asymmetric independent private value model.
