An increasing body of empirical evidence is documenting trends toward rising concentration, profits, and markups in many industries around the world since the 1980s. Two major criticisms of these studies is that concentration and market shares are poorly measured at the national industry level...

Non-controlling minority shareholdings in rivals (NCMS) lower the sustainability of collusion under a wide variety of circumstances. Nevertheless, NCMS are sometimes deemed to facilitate collusion, in particular if the level of NCMS is exogenous. The present paper endogenizes firms' choice of...

This article finds that non-controlling minority shareholdings among competitors lower the sustainability of collusion. This is the case under an even greater variety of situations than was indicated by earlier literature. The collusion destabilizing effect of minority shareholdings is mainly...
