Abstract. Recent research suggests there is substantial wage discrimination against blacks in professional basketball, and that fans are the source of this discrimination. The use of multiple regression analysis does indicate a salary shortfall for black players of fourteen to sixteen percent compared with salaries of white players with comparable on‐court performance. To see whether this shortfall is likely to be due to fan discrimination as the relatively scarce white talent is bid into cities with many white fans, the racial composition of teams is related to the proportion of black residents among the populations of franchise cities. There is statistically significant evidence of geographical sorting by race. Evidence of racial bias is less obvious in contexts where a team's performance would be jeopardized, however. Thus, no evidence is found that fan attendance moves inversely with the percentage of playing time accorded black players, and only weak evidence is found that black players have to be better than white players to enter the National Basketball Association (NBA).
Cooperative learning is a structured, systematic instructional technique in which students work together in small groups toward a common goal. We demonstrate the effectiveness of cooperative learning with an illustrative example for teaching the labor supply curve. Recommendations for introducing the technique, forming groups, the instructor's role during group work, grading and extensions of cooperative learning to other topics are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
