We propose a model to study when an intermediate action can serve as a stepping stone that enables the elimination of a harmful norm. While the intermediate action may facilitate the first “step”, it may also become a new norm. We derive intuitive conditions for stepping stones, which depend...

There is widespread concern that academic freedom is threatened by growing demands for intellectual conformity and attempted censorship from intolerant zealots involving ‘woke wars’ and a ‘cancel culture’ pitting the socially liberal progressive left against the socially conservative...

Addressing hospital emergency department (ED) overcrowding is a critical challenge for many healthcare systems worldwide. Many hospitals (including our partner hospital) have been experimenting with innovative patient flow designs to address this challenge. A promising new design is to separate...

This paper documents the existence of a “Formality Effect” in government communications. Across three online studies and three field experiments in different policy contexts (total N = 67,632), we show that, contrary to scholar and practitioner predictions, formal government communications...

Housing costs across the nation and in Greater Boston are rising, and many policymakers have turned to Inclusionary Zoning (IZ) in an attempt to dampen these effects on their lowest-income residents. Yet design and implementation of IZ policy remains haphazard and often is not well-grounded in...

The United States spends substantially more on health care than most developed countries, yet leaves a greater share of the population uninsured. We suggest that incremental insurance expansions focused on addressing market failures will propagate inefficiencies and are not likely to facilitate...

Society’s transition toward more sustainable energy sources is well underway. But substantially reducing the use of fossil fuels to generate electricity, to power vehicles, and to manufacture the stuff of everyday life will profoundly disrupt the communities that currently dedicate themselves...
