An Exact Arithmetic Ssnip Test For Asymmetric Products

Author

Abstract

The standard application of critical loss analysis to delineate markets is shown to be incorrect when products are asymmetric. A simple delineating criterion is derived that accounts for asymmetries between products without imposing equilibrium conditions or any specific demand structure.
