"Prospect Theory Explains Newsvendor Behavior: The Role of Reference Points" (with Javad Nasiry). Management Science, 2015, 61(12) pp. 3009-3012.
Abstract: Current understanding in operations management is that Prospect Theory, as a theory of decision making under uncertainty, cannot systematically explain the ordering behavior observed in experiments on the newsvendor problem. We suggest this is because the newsvendor's reference point is assumed to be the status quo, i.e., zero payoff. We propose an alternative based on newsvendor's salient payoffs and show that Prospect Theory can, in fact, account for experimental results.
"Quality in Supply Chain Encroachment" (with Albert Ha and Javad Nasiry). Manufacturing & Service Operations Management, 2016, 18(2) pp 280-298.
Abstract: We study a supply chain with manufacturer encroachment in which product quality is endogenous and customers have heterogeneous preferences for quality. It is known that, when quality is exogenous, encroachment could make the retailer better-off. Yet when quality is endogenous and the manufacturer has enough flexibility in adjusting quality, we find that encroachment always makes the retailer worse-off in a large variety of scenarios. We also establish that, while a higher manufacturer's cost of quality hurts the retailer in absence of encroachment, it could benefit the retailer with encroachment. In addition, we show that a manufacturer offering differentiated products through two channels prefers to sell its high-quality product through the direct channel. Contrary to conventional wisdom, quality differentiation does not always benefit either manufacturer or retailer. Our results may explain why, despite extant theoretical predictions, retailers almost always resent encroachment. These findings also suggest that firms must be cautious when adopting quality differentiation as a strategy to ease channel conflict caused by encroachment.
