Nudging at scale: Experimental evidence from FAFSA completion campaigns

The hidden costs of nudging: Experimental evidence from reminders in fundraising∗

We document the hidden costs of one of the most policy-relevant nudges, reminders. Sending reminders, while proven effective in facilitating behavior change, may come at a cost for both senders and receivers. Using a large scale field experiment with a charity, we find that reminders increase donations, but they also substantially increase unsubscriptions from the mailing list. To understand th...

Can Information Technology Energize Voters? Experimental Evidence from the 2000 and 2002 Campaigns

Media-based campaigns have failed to engage the electorate. Few people find political campaigns interesting, nonvoters typically outnumber voters, and public evaluations of candidates, the press, and the political process itself are far from sympathetic (Popkin and McDonald, 2000; Patterson, 2000; Cook et al., 2000). This disconnect between modern campaigns and their intended audience can be tr...

A Large-Scale Educational Campaigns

Educational technology requires a delivery mechanism in order to scale. One method which has not yet seen widespread use is the educational campaign: large-scale, short-term events focused on a specific educational topic, such as the Hour of Code campaign. These are designed to generate media coverage and lend themselves nicely to collaborative or competitive goals, thus potentially leveraging ...

Completion Energies and Scale

The detection of smooth curves in images and their completion over gaps are two important problems in perceptual grouping. In this paper we examine the notion of completion energy and introduce a fast method to compute the most likely completions in images. Specifically, we develop two novel analytic approximations to the curve of least energy. In addition, we introduce a fast numerical method ...
