Living Together, Voting Together: Cohabitation Causes Concordance in Turnout Behavior, and Increases Turnout

With Yosef Bhatti, Jonas Hedegaard Hansen, and Kasper M. Hansen.

We causally identify household effects on turnout. When two voters move together immediately before an election they become more likely to vote regardless of whether they both voted, both abstained, or one voted and one abstained in the previous election (Abstract) (Paper)

Bias in self-reported voting and how it distorts turnout models: disentangling nonresponse bias and overreporting among Danish voters

With Jonas Hedegaard Hansen, Kasper M. Hansen, and Yosef Bhatti. Conditional accept in Political Analysis.

With survey data and administrative data, we show that overreporting and nonresponse bias leads to overestimation of turnout and underestimation of relationships between background and turnout (Abstract) (Paper)

Twice the trouble: Twinning, costs, benefits, and voting

With Kasper M. Hansen. Invitation to revise and resubmit in Journal of Politics. 

Using twinning in the first parity as a natural experiment, we find that an additional child reduces turnout, especially for women. (Abstract) (Paper)

Trickle-up political socialization: The causal effect on turnout of parenting a newly enfranchised voter.

American Political Science Review, 112(3), 2018.

Using a regression discontinuity design, I find that when Danish adolescents come of voting age their parents become more likely to vote. (Abstract) (Paper)

Core and Peripheral Voters: Predictors of Turnout across Three Types of Elections

With Yosef Bhatti, Jonas Hedegaard Hansen, and Kasper M. Hansen.
Accepted for publication in Political Studies.

Across three Danish elections with varying turnot, we explore what characterizes voters and abstainer. We find that inequality in turnout is high when turnout is low (Abstract) (Paper)

How Voter Mobilization from Short Text Messages Travels Within Households and Families: Evidence from two Nationwide Field Experiments

With Yosef Bhatti, Jonas Hedegaard Hansen, and Kasper M. Hansen.
Electoral Studies 50, 2017.

We find that two field experiments where young voters were encouraged to vote by text messages also mobilized their cohabitants. (Abstract) (Paper)

How Election Polls Shape Voting Behavior

With Jonas Hedegaard Hansen, Kasper M. Hansen, and Martin Vinæs Larsen.
Scandinavian Political Studies 40(3), 2017.

We investigate how different voters respond to information from polls through the so-called bandwagon effect in a political context very different from those that have characterized earlier research.  (Abstract) (Paper)

Can Governments Use Get Out The Vote Letters to Solve Europe’s Turnout Crisis? Evidence from a Field Experiment

With Yosef Bhatti, Jonas Hedegaard Hansen, and Kasper M. Hansen.
West European Politics. (Early view).  

We mail direct personal letters with encouragements to vote to more than 60,000 first-time Danish voters. Using validated turnout, we find small positive effects of receiving a letter on turnout, with little difference across eight different letters. (Abstract) (Paper)

Moving the Campaign From the Front Door To the Front Pocket: Field Experimental Evidence on the Effect of Phrasing and Timing of Text Messages on Voter Turnout

With Yosef Bhatti, Jonas Hedegaard Hansen, and Kasper M. Hansen.
Journal Of Election, Public Opinion And Parties 27(3), 2017.  

In four large get-out-the-vote field experiments, we find that sending text messages to voters produces modest effects on turnout. (Abstract) (Paper)

Is  door-to-door  canvassing  effective  in  Europe?  Evidence  from  a  meta-study  across five European countries

With Yosef Bhatti, Jonas Hedegaard Hansen, and Kasper M. Hansen.
British Journal of Political Science. (Early view).  

We compile evidence from door-to-door canvassing experiments in Europe including new studies from Denmark. Door-to-door canvassing appear less efficient in Europe than in the US. (Abstract) (Paper)

You just made it: Individual incumbency advantage under proportional representation

Electoral Studies 44, 2016.

Using a regressions discontinuity design, I find that Danish local councilors enjoy an incumbency advantage. Marginally elected councilors are more likely to rerun for office and to rerun and become elected. (Abstract) (Paper)

How are Voters Influenced by Opinion Polls? The Effect of Polls on Voting Behavior and Party Sympathy

With Jonas Hedegaard Hansen, Kasper M. Hansen, and Martin Vinæs Larsen.
World Political Science Review 12, 2016.

We use a survey experiment to test how voters respond to trends in polls. When voters learn that a party is gaining in the polls, they become more likely to vote for that party. (Abstract) (Paper)

Getting Out the Vote with Evaluative Thinking

With Yosef Bhatti, Jonas Hedegaard Hansen, and Kasper M. Hansen.
American Journal of Evaluation 36(3), 2015.

We find that receiving the constitution in a letter shortly before the election increases turnout among 18-year-old Danish voters. A humorous letter produced a larger effect than a conventional letter. (Abstract) (Paper)
