Short- and long-run competition of retailer pricing strategies

Retailers' pricing strategies are one of the most important determinants of the retail dynamics and the competitive structure of the retail market. Retailers use both short-term and long-term pricing strategies to optimize their market share. This study addresses several critical questions: (1) To what extent do retailers react to competitive price specials? (2) Do retailers alternate price specials of competing brands? and, (3) Can one identify stores or brands, that are price leaders or do retailers/brands set prices independently? We use cointegration analysis to estimate a model which allows us to study both the short- and the long-run dynamics of competitive prices within a single framework

Competition Between Auctions

Even though auctions are capturing an increasing share of commerce, they are typically treated in the theoretical economics literature as isolated. That is, an auction is typically treated as a single seller facing multiple buyers or as a single buyer facing multiple sellers. In this paper, we review the state of the art of competition between auctions. We consider three different types of competition: competition between auctions, competition between formats, and competition between auctioneers vying for auction traffic. We highlight the newest experimental, statistical and analytical methods in the analysis of competition between auctions.auctions, bidding, competition, auction formats, auction houses

Economics, Psychology, and Social Dynamics of Consumer Bidding in Auctions

With increasing numbers of consumers in auction marketplaces, we highlight some recent approaches that bring additional economic, social, and psychological factors to bear on existing economic theory to better understand and explain consumers' behavior in auctions. We also highlight specific research streams that could contribute towards enriching existing economic models of bidding behavior in emerging market mechanisms.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47034/1/11002_2005_Article_5901.pd

A study of bidding behavior in voluntary-pay philanthropic auctions

The authors investigate compliance behavior and revenue implications in winner-pay and voluntary-pay auctions in charity and noncharity settings. In the voluntary-pay format, the seller asks all bidders to pay their own high bid. The authors explore motives and boundary conditions for compliance behavior based on internal and external triggers of social norms. The voluntary-pay format generates higher revenue than the winner-pay format for charity auctions, despite imperfect compliance, but it generates lower revenues in noncharity settings. To characterize bidding strategy, the authors study time to bid, auction choice, and jump bidding and find evidence that bidders in voluntary-pay auctions more commonly use jump bidding and late entry. The findings have important implications for marketing managers, augmenting the growing stream of empirical auction studies and work on corporate social responsibility. Specifically, combining an auction with a charitable cause may result in increased revenues, but managers should ensure that they are accounting for differential compliance rates between auction formats. Even if low-compliance bidders can be identified and screened out, doing so is not advantageous, because noncompliant bidders bid up prices

To bundle or not to bundle: determinants of the profitability of multi-item auctions

This article introduces and empirically tests a conceptual model of the key determinants of the profitability of bundling in auction markets. The model encapsulates hypotheses about how seller revenue from the combined (i.e., bundle) auction of component products relative to that from separate auctions of the components is influenced by the heterogeneity in bidders' product valuations, the degree of complementarity between component products, the particular multi-item selling strategy, and the outside availability of the products. The results of three field experiments show that though bundle auctions tend to be less profitable for noncomplementary and substitute products, they are on average 50% more profitable than separate auctions when there is (even only moderate) complementarity between the component products. The latter effect is greater when the bundle and the separate components are offered at different times, and it is more pronounced for services than for tangible goods. The findings also identify conditions under which each of the essential multi-item selling strategies for fixed-price settings (pure components, pure bundling, and mixed bundling) tends to maximize seller revenue in auctions

The impact of online auction duration

Abstract. One view regarding auction duration suggests that longer auctions would result in more bidders and more bids, which in turn would result in higher prices. An opposing view is that shorter auctions might appeal to impatient bidders, or alternatively that shorter duration might lead to more competitive dynamics. To examine these competing notions, we conduct pairwise comparisons of simultaneous auctions identical in all but duration. The auctions are conducted on two different platforms—eBay and a local auction site. We find that in eBay auctions, longer duration increases the number of bidders and bids and consequently increases final prices by about 11%. In the local auction website with far fewer auctions and a more steady set of participants, the effect is reversed and shorter auctions generate higher prices by about 20%. Both sets of effects are robust and significant. We look at bidding activity on both sites to try to get at the root of that reversal. We find that in eBay auctions, the higher price in the longer duration auction is accompanied by a higher number of participating bidders and a higher number of bids placed in the auction. In the local site, we find that the auction duration does not significantly affect the number of participating bidders or the number of bids placed in an auction. However, the magnitude of jump bids is negatively and significantly correlated with duration. These jump bids are in turn shown to impact final prices
