@techreport{NBERw6580, title = "A New Model of Quality", author = "Kala Krishna and Tor Winston", institution = "National Bureau of Economic Research", type = "Working Paper", series = "Working Paper Series", number = "6580", year = "1998", month = "May", URL = "http://www.nber.org/papers/w6580", abstract = {We develop a new model of quality to capture the idea that even if a customer chooses to purchase a product, it may fail to deliver.' In this event, the customer may wish to choose some other product. We model this as a two stage game where firms first choose quality and then price. We find that in equilibrium, the high quality firm (the one with a higher probability of being able to deliver') will always make higher profits than the low quality one even if costs of quality are sharply increasing. Our work thus provides a reason for high quality niches to be inherently more profitable. The implications for welfare and equilibrium under free entry are also studied.}, }
