We empirically examine the impact of expanded product variety on demand concentration using large data sets from the movie rental industry as our test bed. We find that product variety is likely to increase demand concentration, which goes against the “Long Tail effect” theory predicting...

We examine a large operational data set in a casual restaurant setting to study how coworkers' sales ability level affects other workers' sales performance. We find that waiters react non-linearly to their coworkers' ability. In particular, when coworkers' overall sales ability is low,...

Many consumers have learned to delay purchases, anticipating that prices might decrease. Such strategic or forward-looking behavior has attracted increasing attention from various disciplines, including operations management, information systems, marketing, and economics. However, there is...

The use of global suppliers has increased considerably over the last three decades. Operations management theory establishes that global sourcing requires more units of inventory, but since these units are often procured at a lower cost from global suppliers the capital invested in inventory and...

We study the impact of service attributes (warranty length, after-sales service quality) on consumer demand in the U.S. automobile industry, examining the presence of complementarities/substitution between service attributes and product quality. Our results estimate a median willingness to pay...

The transportation sector’s carbon footprint and dependence on oil are of deep concern to policy makers in many countries. Use of all-electric drive-trains is arguably the most realistic medium-term solution to address these concerns. However, motorist anxiety induced by an electric...

Competition has become an important theme in the operations management literature and, according to recent theoretical and empirical work, the key finding is that firms tend to overstock or overproduce under competition. Following this prediction, one would expect that, after airlines start a...

Product launch - an event when a new product debuts for production in a plant - is an important phase in product development. But launches disrupt manufacturing operations resulting in productivity losses. Using data from North-American automotive plants from years 1999-2007, we estimate that a...

Traditional sourcing arrangements for after-sales product support have centered around physical assets. Typically, a customer would pay the supplier of maintenance services in proportion to the resources used, such as spare parts, that are needed to maintain the product. In recent years, we have...

We analyze the competitive capacity investment timing decisions of both established firms and start-ups entering new markets which are characterized by a high degree of demand uncertainty. Firms may invest in capacity early (when the market is highly uncertain) or late (when market uncertainty...
