67 Katz Shapiro advocate concentrating on what they title the brand new “aggregate diversion ratio” to suggest perhaps the elasticity away from interest in the newest candidate market is actually good enough less than the company-level demand elasticities and so the candidate market is, in fact, market. Guess discover three products in brand new candidate field, Good, B, and C, and the cost of A was increased from the five per cent. Pick in addition to O’Brien Wickelgren, supra notice 31, within 184 (“I’ve shown your inference generally taken regarding crucial loss investigation – you to higher margins create a beneficial merger less inclined to be anticompetitive – can be inconsistent which have financial principle . Within view, critical loss studies keeps led to immense dilemma in regards to the financial situations you to regulate firms’ cost incentives. The process has been misused frequently one arguments which might be contradictory that have first monetary principle have nearly attained a measure of validity inside antitrust instances.”).

Pick, elizabeth.grams., Possibilities Frech, supra notice 31, from the 341-42; O’Brien Wickelgren, supra note 31, within 162, 184; Katz Shapiro, supra note 30, on 52-55.
Katz and you can Shapiro believe the genuine losses is lower than the new vital losses when the and only if your aggregate diversion ratio is higher than the latest important loss
70 Langenfeld Li, supra note 31, during the 332-333. New formula to have important loss was x/(x + m), in which x is the percentage speed changes interesting (elizabeth.g., 5%) and you can meters is the premerger rate pricing margin ((p-c)/p), shown while the a share. Inside the harmony, m = 1/,, in which , ‘s the flexibility regarding demand. In the event that , was small and premerger margins are thus high, it will feel true (because of the definition of flexibility) you to certain price improve often trigger just brief changes in wide variety. Look for O’Brien Wickelgren, supra note 30, in the 167-68; Katz Shapiro, supra mention 29, on fifty-53; Issues Frech, supra mention 29, at the 342-50; Langenfeld Li, supra note 31, on 303-05, 334-337; But look for Scheffman Simons, supra note 29, in the 5-8 (arguing one feedback regarding vital losses research which use the fresh algorithm (meters = 1/,), or perhaps the Lerner Equation, have fun with “the best financial make of pricing” to help you infer that actual loss might be equal or next to critical loss of balance and thereby wrongly move the burden out-of proof so you can defendants).
