      abstract = {A number of Studies have found that unions lower profits,  but controversy continues over whether the union impact is  or is not greater in more concentrated markets or when  firms have greater market shares. The empirical controversy  is linked to two major underlying issues: whether unions  distort capital investment decisions and whether prior  research has tended to understate the level of monopoly  profits in the U.S.economy. Research on the supermarket  industry reveals that indeed unions profits substantially  in this sector. The impact is apparently greater when local  markets are more concentrated or when firms are positioned  better vis-a-vis rivals, but these findings must be  regarded as tentative given the multicollinearity existing  in the data analyzed},
