If consumers can either costly acquire product information or make their purchase decision merely based on the information provided by the seller, how should the seller design her pricing and information policies? When the consumers’ search cost is publicly observed, it has been well-established that the seller’s optimal information provision fully deters the consumer from engaging in information acquisition. We show that this is, however, not necessarily true with privately observed search cost. Moreover, when consumers’ search cost is either relatively high or zero, we characterize the seller’s optimal menu of prices and information policies featuring discriminatory search deterrence levels.
期刊介绍:
The primary objective of the Journal is to provide a forum for work in economic theory which expresses economic ideas using formal mathematical reasoning. For work to add to this primary objective, it is not sufficient that the mathematical reasoning be new and correct. The work must have real economic content. The economic ideas must be interesting and important. These ideas may pertain to any field of economics or any school of economic thought.
