Inside our thoughts, crucial losings investigation enjoys led to immense distress in regards to the financial things you to definitely govern firms’ cost bonuses. The technique might have been misused so frequently one arguments which might be contradictory having first economic principle keeps nearly gained a way of measuring validity when you look at the antitrust instances.”).

Katz and you may Shapiro argue that the real losings was less than the newest vital loss down dating if the and just if your aggregate diversion proportion exceeds the fresh critical losings

70 Langenfeld Li, supra notice 30, from the 332-333. New algorithm to possess crucial loss was x/(x + m), in which x is the fee rates changes of great interest (age.grams., 5%) and you can meters is the premerger speed rates margin ((p-c)/p), shown just like the a share. When you look at the balance, meters = 1/,, where , is the flexibility of request. If the , is small and premerger margins are therefore highest, it will feel real (by concept of flexibility) you to definitely a given rates increase will lead to only brief changes in numbers.
