Herd immunity at what price? Using auctions to estimate what university students must be paid to get the flu vaccine.

There is significant resistance to vaccinations. Fewer than half of adults get a flu shot in the United States in a typical year, and a large minority of Americans say they will not get vaccinated against COVID-19. This resistance to vaccines creates challenges for both public health and the economy.

Estimating the price elasticity of demand for JUUL E-cigarettes among teens.

Background: The widespread popularity of e-cigarettes, particularly JUUL, has led to an alarming increase in teen nicotine use, reversing a 40-year trend. One key question is how sensitive teens' demand for JUUL is to changes in price.

Methods: We estimate the price elasticity of demand using results from an experimental auction where teen nicotine users and nonusers bid on a JUUL kit.

Going Once, Going Twice: Using Willingness-to-Accept Auctions to Promote Smoking Cessation.

Introduction: Incentive-based smoking cessation interventions increase quit rates. The optimal incentive, however, is unknown. We used a willingness-to-accept (WTA) auction where smokers submitted bids indicating the incentive they would need to receive for 1 week of smoking cessation.

Which smokers adopt e-cigarettes and at what price? An experimental estimation of price elasticity of demand and factors correlated with e-cigarette adoption.

E-cigarette use has surged in recent years. Many of these new users are cigarette smokers. It is unclear whether e-cigarette adoption by smokers will lead to improved public health due to uncertainty about whether e-cigarettes help smokers quit using cigarettes and about whether ongoing dual use reduces exposure to toxins.

Does Winning an Experimental Auction Change People's Behavior? An Application to E-cigarettes.

Experimental auctions allow researchers to estimate demand for products like e-cigarettes in a non-hypothetical environment where participants face real and immediate consequences for their bids. However, because auction winners actually purchase the product they bid on, participants may be introduced to a product they otherwise would not have discovered. Based on an experimental auction where 432 participants bid to buy e-cigarettes, we found that auction winners are significantly more likely to be using e-cigarettes two weeks, six weeks, and six months after the study but are no less likely to be daily cigarette smokers.

How much is social media worth? Estimating the value of Facebook by paying users to stop using it.

Facebook, the online social network, has more than 2 billion global users. Because those users do not pay for the service, its benefits are hard to measure. We report the results of a series of three non-hypothetical auction experiments where winners are paid to deactivate their Facebook accounts for up to one year.

Effect of brand and advertising medium on demand for e-cigarettes: Evidence from an experimental auction.

Print and television advertisements for e-cigarettes are currently legal in the United States. Given that e-cigarettes are a lower-risk alternative to cigarettes, these ads could have a positive public health impact if they motivate smokers to switch to e-cigarettes. However, the public health impact of e-cigarette ads could be negative if ads increase demand for both e-cigarettes and cigarettes.

Using Experimental Auctions to Examine Demand for E-Cigarettes.

Background: E-cigarettes are the latest in a line of potentially reduced exposure products that have garnered interest among smokers.

Methods: In this paper, we use experimental auctions to estimate smokers' demand for e-cigarettes and to assess the impact of advertisements on willingness to pay. These are actual auctions, with winners and losers, which means hypothetical biases often seen in surveys are minimized.

Estimating the impact of pictorial health warnings and "plain" cigarette packaging: evidence from experimental auctions among adult smokers in the United States.

Objective: To estimate differences in demand for cigarette packages with different packaging and health warning label formats.

Methods: Adult smokers (n=404) in four states participated in experimental auctions. Participants bid on two of four experimental conditions, each involving a different health warning label format but with the same warning message: (1) text on 50% of pack side; (2) text on 50% of the pack front and back; (3) text with a graphic picture on 50% of the pack front and back; and (4) same as previous format, but without brand imagery.
