Competizione sui mercati internazionali e misure del potere di mercato. Il caso dell'industria italiana dell'elettrodomestico
Starting from the Baker-Bresanahan (1988) seminal paper, an extended version of their econometric technique is implemented for estimating the residual demand curve a group of exporters faces in a particular export market. The elasticity of the exporters' residual demand curve is identified by exchange rates shocks that rotate the supply relation of the exporters competitors located in other countries. I apply this approach to the measurement of market power of Italian "white goods" manufacturers in the European market. The main result is that the "residual demand approach" provides estimates of market power sufficiently consistent with other indicators of competition (i.e. market shares), even if results are not so clearcut when there is a role for product specificity and the geographical location of competitors.
