We study two generic versions of public goods problems: in Provision problems, the good does not exist initially and needs to be provided; Maintenance already exists maintained. In four lab online experiments (n=2,105), we document a robust asymmetry preferences perceptions incentive-equivalent these problems. find fewer conditional cooperators more free riders than Provision, difference that i...

Motivational crowding-out theory establishes that the effectiveness of financial incentive schemes, like pay-for-performance, crucially depends on the underlying social preferences of health workers. In this paper we study the extent to which heterogeneity in the strength and structure of social preferences is related to career choices by testing whether preferences vary systematically between ...

The finding that the preferences of middle-income Americans are ignored when they diverge from the preferences of the rich is one of the most widely accepted and influential conclusions in political science research today. I offer a cautionary note regarding this conclusion. I demonstrate that even on those issues for which the preferences of the wealthy and those in the middle diverge, policy ...

Empirical studies of the connection between citizen preferences and legislator actions have largely focused on the preferences of a district’s average or median voter. While many theories suggest that preference heterogeneity should also affect this connection, few empirical analyses have rigorously tested claims about the distribution of individual voter preferences. In this paper, we use a un...

We present a simple and natural non-pricing mechanism for allocating divisible goods among strategic agents having lexicographic preferences. Our mechanism has favorable properties of strategy-proofness (incentive compatibility). In addition (and even when extended to the case of Leontief bundles) it enjoys Pareto efficiency, envy-freeness, and time efficiency. 1998 ACM Subject Classification F...

BACKGROUND Mild cognitive impairment (MCI) or mild neurocognitive disorder is a well-established clinical entity included in current diagnostic guidelines for Alzheimer's disease and in major psychiatric classifications. In all, a loosely defined concern obtained from conceptually different sources (the individual, a knowledgeable informant, or a clinician) regarding a decline in cognition and ...
