 note = {P, In a simplified case, criteria for optimum tariff (subsidy) by Brander and Spencer and by Jones are equivalent to each other and the Metzler paradox cannot occur. In a more general case with general equilibrium income effects of tariff, a necessary condition for the Metzler paradox is that importables must be strongly inferior and/or the tariff can reduce extremely the slope of the demand curve. So we may safely rule it out under the normal goods assumption.},
