Most quantitative tools for assessing competitive effects of mergers rely heavily on recapture ratios (also known as aggregate diversion ratios). Recapture ratios measure the proportion of customers switching away from a product that is captured by other products within the market rather than outside the market. We propose a simple approach for approximating recapture ratios which can be usefully applied in merger and competition cases.
