Social interdependence is believed to play an important role in how people make individual choices. This paper presents a simple model constructed on the premise that people are motivated by their own payoff as well as by how their actions compare with those of other people in their reference...

Economic experiments conducted in laboratories employing an induced-values methodology can report on allocative efficiencies observed. This methodology is limited by requiring the experimenter to know subjects' motivations, an impossibility in field experiments. Allocative efficiency implies a...

Most economic models are based on the self-interest hypothesis that assumes that all people are exclusively motivated by their material self-interest. In recent years experimental economists have gathered overwhelming evidence that systematically refutes the self-interest hypothesis and suggests...

Anecdotal, empirical, and experimental evidence suggests that offering extrinsic rewards for certain activities can reduce people's willingness to engage in those activities voluntarily. We propose a simple rationale for this 'crowding out' phenomenon, using standard economic arguments. The...

Whereas the rational choice approach to international law has been widely accepted in legal scholarship and international relations theory, challenges to the rational choice paradigm in economic analysis of international law have hitherto not been systematically explored. Nevertheless,...

Anecdotal, empirical, and experimental evidence suggests that offering extrinsic rewards for certain activities can reduce people's willingness to engage in those activities voluntarily. We propose a simple rationale for this "crowding out" phenomenon, using standard economic arguments. The...

The anchoring-and-adjustment heuristic has been studied in numerous experimental settings and is increasingly drawn upon to explain systematically biased decisions in economic areas as diverse as auctions, real estate pricing, sports betting and forecasting. In these cases, anchors result from...

Economics students have been shown to exhibit more selfishness than other students. Because the literature identifies the impact of long-term exposure to economics instruction (e.g., taking a course), it cannot isolate the specific course content responsible; nor can selection, peer effects, or...

This article experimentally examines voluntary contributions when group members' marginal returns to the public good vary. The experiment implements two marginal return types, low and high, and uses the information that members have about the heterogeneity to identify the applied contribution...
