Come across including O’Brien Wickelgren, supra mention 29, from the 184 («I’ve found that the inference normally removed regarding crucial loss studies — that higher margins build a beneficial merger less likely to want to be anticompetitive — is normally inconsistent which have economic idea . Within our thoughts, vital losings analysis provides triggered tremendous misunderstandings concerning economic issues you to definitely control firms’ cost incentives. The strategy might have been misused so frequently you to definitely arguments which might be inconsistent that have first monetary idea keeps nearly achieved a way of measuring legitimacy inside the antitrust cases.»).

Katz and Shapiro believe the real losses was lower than the brand new important loss if and only whether your aggregate diversion ratio is higher than the vital losings

70 Langenfeld Li, supra notice 31, from the 332-333. The algorithm to have vital loss try x/(x + m), in which x ‘s the percentage price changes of great interest (age.g., 5%) and you will yards is the premerger rate rates margin ((p-c)/p), indicated as a share. Within the harmony, m = 1/,, where , is the elasticity out of request. If the , try smaller than average premerger margins are thus large, it is going to become correct (by the definition of flexibility) that a given rate raise have a tendency to lead to merely small alterations in numbers. Come across O’Brien Wickelgren, supra notice 29, during the 167-68; Katz Shapiro, supra mention 30, within 50-53; Possibilities Frech, supra notice 30, in the 342-50; Langenfeld Li, supra notice 31, from the 303-05, 334-337; But discover Scheffman Simons, supra notice 31, from the 5-8 (arguing you to reviews from crucial loss studies that use the fresh new formula (yards = 1/,), and/or Lerner Formula, play with «the best monetary model of prices» so you can infer that losings could well be equivalent or near to critical losing balance and you will and therefore wrongly move the burden out of facts to defendants).
