Heterogeneous firm productivity seems to provide an argument for governments to pursue `pick-the-winner' strategies by subsidizing highly productive firms more, or taxing them less, than their less productive counterparts. We appraise this argument by studying the optimal choice of effective tax...

This paper analyzes measures that limit firms’ profit shifting activities in a model that incorporates heterogeneous firm productivity and monopolistic competition. Such measures, e.g. thin capitalization rules, have become increasingly widespread as governments have reacted to growing profit...

This paper analyzes competition for capital between welfare-maximizing gov- ernments in a framework with agglomeration tendencies and asymmetric union- ization.
