Remanufacturing is a product recovery option that upgrades the quality of returns to “as-good-as-new” conditions. Remanufactured products cost less, and are sold with the same or better warranty as for new products. In this paper, we consider a duopoly environment with two manufacturers in direct competition selling their respective new products on the primary market. Specifically, we address t...

We examine the effect of online consumer reviews on the sales of video games. An inherent problem in measuring the influence of reviews on demand is that products receiving good reviews tend to be of high quality, and it is difficult to determine whether the review or the quality is responsible for the high demand. To circumvent this problem, we consider video games that are developed for both ...

One way is through Functional Sales, i.e. shifting the focus from the production of products to the production of services. Functional Sales and Design for Environment (DfE) have many common issues, e.g. the life cycle perspective. The paper’s aim is to highlight a proposed interactive design met...

Academics and industry observers sharply disagree on how online distribution will change the number and variety of products that consumers purchase. Proponents of the “long-tail” idea argue that a significant increase in the supply of products through online channels will fuel a shift in consumption away from hits to a vast number of lower-selling niche products. The “superstars” theory predict...

When a disease outbreak is detected, identifying the contaminated food quickly is vital to minim...

Recommender systems are frequently used as part of online shops to help consumers browse through large product offerings by recommending those products which are the most relevant for them. Although consumers’ interactions with recommender systems have been subject to substantial research, it is still unclear what the effect on aggregated sales diversity is, i.e. whether this leads to predomina...

We examine the effects of product variety and inventory levels on store sales. Using 4 years of data from stores of a large retailer, we show that increases in product variety and inventory levels are both associated with higher sales. We also show that increasing product variety and inventory levels has an indirect negative effect on store sales through their impact on phantom products—product...

Junk food consumption is associated with rising obesity rates in the United States. While a "junk food" specific tax is a potential public health intervention, a majority of states already impose sales taxes on certain junk food and soft drinks.
