Signal-jamming in the Frequency Domain

Author

  • Bart Taub

Abstract

I examine strategic behaviour for a duopoly in a noisy environment. Firms attempt to learn the value of the rival’s privately observed demand shocks via a noisy signal of price, and at the same time firms attempt to obfuscate that signal by producing excess output on the publicly observable signals, that is, they signal jam. In a dynamic setting firms also distort the intertemporal structure of output keyed to the publicly observable demand shock process in order to disguise their private shocks. The net outcome is to radically increase the persistence of output over its full-information value.
