The Tax Cuts and Jobs Act eliminated federal charitable giving incentives for roughly 20 percent of US income-tax payers. We study the impact of this on giving. Basic theory and our empirical results suggest heterogeneous effects for taxpayers with different amounts of itemizable expenses....

COVID-19 vaccines are widely available in wealthy countries, yet many people remain unvaccinated. Understanding the effectiveness -- or lack thereof -- of popular vaccination campaign strategies is therefore critical. In this paper, we report results from two studies that tested strategies...

Research on the causal effects of online advertising on consumer welfare is limited due to challenges in running large-scale field experiments and tracking effects over extended periods. We analyze a long-running field experiment of online advertising in which a random 0.5% subset of all users...

Asking entails the risk of rejection, which can be painful: since unawareness of the need can no longer be...

What causes adverse policing outcomes, such as excessive uses of force and unnecessary arrests? Prevailing explanations focus on problematic officers or deficient regulations and oversight. Here, we introduce a new, overlooked perspective. We suggest that the cognitive demands inherent in...

The purpose of this paper is to conduct a theoretical and empirical analysis of the nexus between long-term care insurance (LTCI), formal care, informal (family) care, and bequests. In our empirical analysis, we use micro data from the Japan Household Panel Survey on Consumer Preferences and...
