Abstract
Why do people vote? We design a field experiment to estimate a model of voting 'because others will ask'. The expectation of being asked motivates turnout if individuals derive pride from telling others that they voted, or feel shame from admitting that they did not vote, provided that lying is costly. In a door-to-door survey about election turnout, we experimentally vary (i) the informational content and use of a flyer pre-announcing the survey, (ii) the duration and payment for the survey, and (iii) the incentives to lie about past voting. The experimental results indicate significant social image concerns. For the 2010 Congressional election, we estimate a value of voting 'to tell others' of about $15, contributing 2 percentage points to turnout. Lastly, we evaluate a get-out-the-vote intervention in which we tell potential voters that we will ask if they voted.

Experimental Details

Interventions

Intervention(s)
The experiment is a combination of four crossed interventions: (i) flyer treatments, (ii) payment and duration of the survey, (iii) survey content announcement at the door, and (iv) incentives to claim non-voter status. One of five different flyers were left at each house, informing the household about the next day's survey: No Flyer, Survey Flyer, Election Flyer, Opt-Out Flyer, and Election Opt-Out Flyer. Survey flyers simply stated the household would be asked to complete a survey. Election flyers specified that the survey would be about 'your voter participation in the 2010 congressional election." Households in the Opt-Out Flyer treatment receive a flyer as in the Survey Flyer treatment, except for an added check-box which the household can mark if it does not wish to be disturbed. Similarly, the flyer in the Election Opt-Out Flyer treatment has an added opt-out check box.

Second, payment ($5 or $10) and the time necessary (5 or 10 minutes) for the survey were randomly varied and pre-announced on flyers. Lastly, half the respondents of the ten-minute survey were informed that the survey would be eight minutes shorter if they stated that they did not vote in the 2010 congressional election. For voters, this treatment amounts to an incentive to lie and permits us to quantify the disutility of voters were they to say (untruthfully) that they did not vote. For the 50 percent of non-voters who lie without such incentives, this treatment provides an incentive to tell the truth.

In a secondary experiment, in the five days before the election date, researchers posted a flyer on the doorknob of households informing them that 'researchers will contact you within three weeks of the election [...] to conduct a survey on your voter participation.'

Experimental Design

Experimental Design
In this paper, researchers estimate a model of voting 'to tell others' by using an experiment which randomized flyers and surveys about voting behaviors. The field experiment had three main sets of treatments: 1) randomization of information on the flyer, 2) randomized and pre-announced payment for and length of the survey, and 3) randomized incentives meant to evoke different responses to a question about voter turnout.
Experimental Design Details
Randomization Method
Every half-hour, the surveyor moves to a different street in the neighborhood and begins a new route of 13 homes, typically entering a different treatment in the next route.
Randomization Unit
