“…Forrest, Simmons, and Buraimo (2005), for example, reported that the coefficient associated with the difference in relative wages has a negative and statistically significant sign. In Buraimo (2008) and Buraimo and Simmons (2015), the coefficients associated with the absolute difference in relative wages are not statistically significant, even though this variable is relevant in determining the selection of matches to be broadcasted. Cox (2015) modelled the outcome uncertainty using the difference in win probabilities; when statistically significant, the associated coefficient is negative, supporting the UOH.…”
