Justin Winkler has a new thesis from Haverford (pdf):
This paper analyzes the impact that the influx of foreign players has had on the salaries and labor market outcomes of domestic players in the National Basketball Association (NBA). The study builds on previous literature in the field of labor economics by examining this research question in a highly specialized labor market with a rigid salary structure. First, an unbalanced panel data set at the player-year level from 1990-2008 is used in combination with a log-linear regression model to estimate the impact that the number of foreign players in the NBA has on the wages of domestic players. Results are insignificant. A handcrafted dataset tracking the careers of Chad Ford’s top 50 American prospects from 2001 through 2015 is used with a series of ordered logistic regressions to examine foreign players’ impact on the career length and outcomes of American players. Additional ordinary least squares regressions are used to estimate the career quality of American prospects by the quality of the leagues in which they played. Results of all regressions investigating the career outcomes of American prospects are also insignificant.
