The Importance of taste in experimental auctions: consumers’ valuation of calorie and sweetener labeling of soft drinks

A majority of purchases that consumers make are classified as repeat purchases. One of the main reasons why consumers make repeat food purchases is the food's taste. Therefore, we examined the importance of including taste testing in nonhypothetical experimental auctions. Specifically, we used two experiments to determine consumers’ willingness to pay for soft drinks labeled with different calorie and sweetener information. In Experiment 1, participants tasted the soft drinks prior to the bidding rounds. In Experiment 2, participants did not taste the soft drinks prior to the bidding rounds. Bidding behavior for the soft drinks was significantly different between Experiment 1 and Experiment 2. Results suggest that including taste testing in the design of experimental auctions is important to accurately capture consumers’ willingness to pay for foods that are purchased repeatedly. Results also imply that policies aimed at combating obesity by making the calorie content of foods more visible may not produce desired outcomes.

The Effect of Social Cues on Sniping Behavior in Internet Auctions: Field Evidence and a Lab Experiment

This research explores how social cues presented in an online auction affect sniping behavior. Sniping is a strategy of placing a bid on an item in the very ending stages of an auction with a pre-determined ending time in an attempt to win the auction. Such a strategy conceals the intentions of the bidder until the last moments of the auction and minimizes the possibility of other opposing bidders submitting higher bids due to the short period of time left to respond. The research includes two field studies and a lab experiment indicating that sniping appears to be influenced by social factors, that is, when there are a greater number of bidders in the auction or the auction site provides social information about the bidders, the relative use of sniping increases. This research supports the perspective that bidders rely on others' bidding behavior and characteristics as an indication of the true value of the item on sale, and is one of the first studies in the literature which takes this perspective.

Efficient bidding with externalities

We implement a family of efficient proposals to share benefits generated in environments with externalities. These proposals extend the Shapley value to games with externalities and are parametrized through the method by which the externalities are averaged. We construct two slightly different mechanisms: one for environments with negative externalities and the other for positive externalities. We show that the subgame perfect equilibrium outcomes of these mechanisms coincide with the sharing proposals.     

Your Call: eBay and Demand for the iPhone 4☆

The iPhone 4 was introduced into the UK market on 24^th June 2010 to significant consumer interest. Demand revealed itself exceeding supply through conventional channels, since there was very extensive activity in terms of bidding on eBay auctions for the product. We monitored all UK eBay transactions on the iPhone 4 for six weeks from introduction, with total transactions amounting to around £1.5m. We analyse determinants of winning bids in terms of characteristics of the phone, the seller, and the buyer. Our most notable and novel finding relative to previous studies is a very significant premium over list price being paid in almost all cases, with positive uplift factors including whether the phone was unlocked and whether it could be sold overseas. Demand fell over time, as evidenced by lower achieved prices, but the fall in price was relatively modest. A significant premium of 32GB over 16GB versions is revealed.
