DESCRIPTION:*Discrimination represents an important moral problem in the fi
 eld of business ethics. While most of the extant literature studies discrim
 ination against employees\, we examine how changes in the local information
  environment influence organizational decision-making\, focusing on the dis
 criminatory behavior of frontline employees. Leveraging a staggered differe
 nce-in-differences design\, we exploit the closures of local newspapers acr
 oss U.S. counties between 2009 and 2022 to assess how these closures on dis
 criminatory behavior in mortgage lending. Analyzing over 187 million loan a
 pplications\, we find that the loss of local journalism is associated with 
 significantly higher denial rates for applicants who are ethnic minorities 
 or women\, even after controlling for loan and applicant characteristics\, 
 bank fixed effects\, and local economic trends. We find stronger effects in
  more heterogenous communities\, pointing to local journalism as a unifying
  force in otherwise fragmented counties. Our findings contribute to the bus
 iness ethics literature by documenting how local newspapers play a critical
  role in indirectly reducing discriminatory practices. These results highli
 ght how persistent\, community-level information exposure can shape ethical
  behavior in organizations.**This paper presents an integrated axiomatic fr
 amework for measuring how much of a single attribute is distributed among 
 a collection of agents\, depending on whether the attribute is measured on
  a cardinal or ordinal scale. We require that comparisons of distributions 
 be consistent with how the attribute studied is expressed - positively (e.
 g.utility) or negatively (e.g. disutility) - a property we term reversal c
 onsistency. We show that the only anonymous\, Paretian and separable orderi
 ng satisfying the cardinal reversal consistency is the ordering defined by 
 the mean. In the ordinal case\, the only anonymous and Paretian ordering th
 at satisfies the ordinal reversal consistency - when restricting our compar
 isons to distributions with a unique median - is the ordering defined by th
 e median. We establish an impossibility theorem showing that no anonymous a
 nd Paretian ordering satisfies ordinal reversal consistency when the media
 n can be non-unique. Finally\, we explore the joint characterization of th
 e lower and upper medians as a possible way to circumvent this impossibili
