摘要 |
We examine optimal tariffs in an environment with vertical
specialization where the Home country specializes
in final goods and the Foreign country specializes in intermediate inputs. A matched
Home–Foreign pair bargains simultaneously over the input price and the level of
output, and competes a` la Cournot with other matched pairs in markets. We
find that the optimal Home tariff rate is strictly decreasing in the bargaining
power of Home firms, and an increase in the Home firms' bargaining power might
therefore raise Foreign profits. Under an endogenous market structure with entry
followed by matching, the relationship between bargaining power and output is
non-monotone if the demand function is strictly concave or convex. This in
turn induces a non-monotone relationship between the optimal tariff and
bargaining power for a class of demand functions. For
linear demand, free trade is optimal irrespective of bargaining power. We show that
non-monotonicity result is retained under endogenous bargaining power. |
