essential to move toward a more accurate post-merger price simulation model: change in marginal costs, change in product lines …Horizontal-merger price simulations, which rely upon pre-merger data to predict post-merger prices, have been proposed …-product industries makes empirical investigations of simulation performance extremely difficult, and raises many questions regarding the …

This paper uses revealed preference inequalities to provide tight nonparametric bounds on consumer responses to price … changes. Price responses are allowed to vary nonparametrically across the income distribution by exploiting microdata on … consumer expenditures and incomes over a finite set of discrete relative price changes. This is achieved by combining the …
