Nonparametric Identification and Estimation of Multi-Unit, Sequential, Oral, Ascending-Price Auctions With Asymmetric Bidders

Within the independent private-values paradigm, we derive the data-generating process of the winning bid for the last unit sold at multi-unit sequential English auctions when bidder valuations are draws from different distributions; i.e., in the presence of asymmetries. When the identity of the winner as well as the number of units won by each bidder in previous stages of the auction are observed, we demonstrate nonparametric identification and then propose two estimation strategies, one based on the empirical distribution function of winning bids for the last unit sold and the other based on approximation methods using orthogonal polynomials. We apply our methods to daily data from fish auctions held in Grenå, Denmark. For single-unit supply, we use our estimates to compare the revenues a seller could expect to earn were a Dutch auction employed instead.Asymmetric, Multi-unit, Sequential, Oral, Ascending-price fish auctions, Dutch auctions, Nonparametric identification and estimation

Intertextual Dialogue and Humanization in David Simon’s <i>The Corner</i>

This article presents a reading of the six-part HBO miniseries The Corner (2000) which was co-written by David Simon and David Mills and directed by Charles S. Dutton. Focusing in particular on its use of flashbacks, intertextuality, melodrama, and realism, the article argues that this series has its chief interest in humanizing a group of people—namely drug addicts—who otherwise are relegated to the margins of popular television shows. Taking a point of departure in showing how a family in an impoverished neighborhood is afflicted by drug addiction, The Corner tries to counter existing discourses about people living in blighted inner-city neighborhoods, and through intertextual dialogue with the genre of the “hood film”—exemplified by John Singleton’s Boyz n the Hood (1991)—The Corner explicitly makes a different depiction of similar subject matters than is generally found in “hood films.” The article shows how The Corner’s societal critique is embedded in both realism and melodrama as a way of insisting on the veracity of its subject matter while also using emotionality—pathos—as a core part of its appeal and political argumentation

Fremtidens arbejdsmiljø — et debatoplæg til arbejdsministerens nye arbejdsmiljøgruppe

Dette her er et oplæg til den nye arbejdsmiljøgruppe, som arbejdsminister Hygum har annonceret at han vil nedsætte i efteråret. Gruppen skal besvare spørgsmålet: 'Er vi gearet til at løse arbejdsmiljøopgaverne i videnssamfundet?' siger arbejdsministeren
