“…As known,Eaton and Grossman (1986) have shown that the optimal choice for governments is a tax (instead of a subsidy) in the case of price (instead of quantity) competition. In such a case, the policy intervention is welfare superior (for producing countries) to free trade.11 For the sake of clarity, we recall here that the Brander and Spencer's result always holds true also under the preceding extensions to the managerial delegation surveyed in the Introduction and thus only in the present model with owner-manager bargaining the presence of managerial delegation may modify such results.12 For instance, this alternative view of managerial contracts has been recently investigated byKopel, Pezzino, and Ressi (2015) in a location model framework.13 The expressions for q(s i , s j ), π(s i , s j ), and SW(s i , s j ) are too long and omitted here for brevity. 14 The equilibrium outcomes under free trade are easily obtained by setting s i = s j = 0 in Equations A.7-A.13.…”
