Innovate Versus Imitate: Theory and Experimental Evidence

Abstract

Abstract We model and experimentally evaluate the trade-off between innovation and imitation commonly faced by firms. Innovation involves searching for a high payoff opportunity, but paying a cost in order to do so. Imitation involves avoiding that search cost and copying the most successful payoff opportunity uncovered thus far. We formulate a novel model of sequential innovation versus imitation decisions made by a group of n regret minimizing agents. We analyze the consequences of complete versus incomplete information about the distribution of payoffs from innovation on agents’ decisions. We then study these predictions in a laboratory experiment where we find evidence in support of our theoretical predictions.
