We present a dictator game experiment where the recipients are local charities that serve the poor. Donors consist of approximately 1000 participants from a nationally representative respondent panel that is maintained by a private survey research firm, Knowledge Networks. We randomly manipulate...

We discuss self-interested uses of equity arguments in international climate negotiations. Using unique data from a world-wide survey of agents involved in international climate policy, we show that the perceived support of different equity rules by countries or groups of countries may be...

In Fairness versus Welfare, we advance the thesis that social policies should be assessed based entirely on their effects on individuals' well-being. This thesis implies that no independent weight should be accorded to notions of fairness (other than many purely distributive notions). We support...

What is inequality in health? Are economists' standard tools for measuring income inequality relevant or useful for measuring it? Does income protect health and does income inequality endanger it? I discuss two different concepts of health inequality and relate each of them to the literature on...

Algorithms (in some form) are already widely used in the criminal justice system. We draw lessons from this experience for what is to come for the rest of society as machine learning diffuses. We find economists and other social scientists have a key role to play in shaping the impact of...

We conduct a lab-in-the-field experiment to identify parents' preferences for investing in their children. The experiment exogenously varied the short-run returns to educational investments to identify how much parents care about maximizing total household earnings, minimizing cross-sibling...

We analyze how separations responded to arbitrary differences in own and peer wages at a large U.S. retailer. Regression-discontinuity estimates imply large causal effects of own wages on separations, and on quits in particular. However, this own-wage response could reflect comparisons either to...

Life annuities can be a valuable component of the decumulation stage of wealth during retirement. While economists argue that most retirees should annuitize, actual demand in the marketplace is low. We analyze data from two studies to determine how measurable individual differences among...
