Consumer Uncertainty and Purchase Decision Reversals: Theory and Evidence

This research examines how prepurchase information that reduces consumer uncertainty about a product or service can affect consumer decisions to reverse an initial product purchase or service enrollment decision. One belief commonly held by retailers is that provision of greater amounts of information before the purchase reduces decision reversals. We provide theory and evidence showing conditions under which uncertainty-reducing information provided before the purchase decision can actually increase the number of decision reversals. Predictions generated from an analytical model of consumer behavior incorporating behavioral theory of reference-dependence are complemented by empirical evidence from both a controlled behavioral experiment and econometric analysis of archival data. Combined, the theory and evidence suggest that managers should be aware that their information provision decisions taken to reduce decision reversals may actually increase them.
