We consider auctions with price externality where all bidders derive utility from the winning price, such as charity auctions. In addition to the benefit to the winning bidder, all bidders obtain a benefit that is increasing in the winning price. Theory makes two predictions in such settings:...

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...

A price matching guarantee (PMG) is a promise to match a competitor's lower price. A price beating guarantee (PBG) is a promise to beat that price. This study presents a large-scale controlled field experiment involving pairs of simultaneous auctions to examine the impact of the presence versus...

Charities increasingly utilize social media tools in fundraising. This research studies three mechanisms by which Facebook “likes” affect charitable behavior: (1) signaling, (2) commitment escalation, and (3) social contagion. The first study manipulates the number of Facebook likes on a...

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...

Fundraising involves the simultaneous consideration of three actors the donor, the charitable organization raising the funds, and the beneficiary. Successful fundraising appeals match donor motivations to preferred organizational and beneficiary attributes while acknowledging the influence of...

Internet auctions are common in nearly all consumer categories. Hence, it is not surprising that a great deal of research has emerged on the topic in recent years. New design and format considerations and a wealth of available data from various platforms provide new questions and promising...

The purpose of this study is to determine how self-driven (intrinsic motivators) and monetary incentives (extrinsic motivators) are mediated by effort to affect fundraising outcomes. This integration sheds light on crowding out between the two types of incentives as well the drivers of...
