Objective: Previous social-psychological research has demonstrated the positive effects of online bystander programs on various crime-related outcomes, while information systems research has demonstrated the ability of gamification to improve motivation, engagement, and learning. This study...

We study a form of threshold matching in fundraising where donations above a certain threshold are topped up with a fixed amount. We show theoretically that threshold matching can induce crowding in if appropriately personalized. In a field experiment, we explore how thresholds should be chosen...

This paper examines the case for randomized controlled trials in economics. I revisit my previous paper "Randomization and Social Policy Evaluation" and update its message. I present a brief summary of the history of randomization in economics. I identify two waves of enthusiasm for the method...

Some companies engage in mass fundraising in addition to their core business. Via a corporate social responsibility (CSR) channel this may increase sales. However, ask avoidance, if present, could imply that fundraising activities may harm a company's core business. We examine how asking for...

We conducted a randomized controlled trial involving nearly 700 customer-service representatives (CSRs) in a Canadian government service agency to study whether providing CSRs with performance feedback with or without peer comparison affected their subsequent organ donor registration rates....

We study how job seekers' understanding of complex unemployment benefit rules affects their labor market performance. Combining data from a large-scale scale field experiment, detailed administrative records, and a survey of unemployed job seekers, we document three main results. First, job...

We study how online job search advice affects the job search strategies and labor market outcomes of unemployed workers. In a large-scale field experiment, we provide job seekers with vacancy information and occupational recommendations through an online dashboard. A clustered randomization...

In a large-scale natural field experiment, we partnered with a micro-lending company in Kyrgyzstan that asked over 180,000 of its clients for donations to social projects as a form of corporate philanthropy. In a 2x2 design, we explored two main (pre-registered) hypotheses about giving by the...

Does online fundraising increase charitable giving? Using the Facebook advertising tool, we implemented a natural field experiment across Germany, randomly assigning almost 8,000 postal codes to Save the Children fundraising videos or to a pure control. We studied changes in the donation revenue...

We study how salary history disclosures affect employer demand, and how salary history bans shape hiring and wages. We show how these effects depend on the properties of the labor market, and we measure the key properties using a novel, two-sided field experiment. Our field experiment features...
