We propose a theoretical framework to predict the impact of inward FDI on the host country's incumbent firms' price-cost margins, according to the mode of entry of FDI We then investigate empirically the competitive discipline effect exerted by both imports and FDI on manufacturing plant-level price-cost margins in the UK, for the period 1991-2001. We estimate different specifications of the price-cost margin equation with both fixed-effects instrumental panel estimator and efficient generalized method of moments estimator with clustering correction.
