An AIDS epidemic threatens Ethiopia with a long wave of premature adult mortality, and thus with an enduring setback to capital formation and economic growth. The authors develop a two-sector model with three overlapping generations and intersectorally mobile labor, in which young adults...

An AIDS epidemic threatens Ethiopia with a long wave of premature adult mortality, and thus with an enduring setback to capital formation and economic growth. The authors develop a two-sector model with three overlapping generations and intersectorally mobile labor, in which young adults...

This paper considers a procedurally fair provision mechanism that allows members of a small group to determine, through their bids, which project to implement. Previous experiments with (only) costly projects have demonstrated that the mechanism is efficiency enhancing. Our experiment tests...

This paper derives and justifies a procedurally fair bidding mechanism and reviews experiments that apply the mechanism to public projects pro- vision. In the experiments, not all parties benefit from provision, and the projects' costs can be negative. The experimental results indicate that the...

Previous studies have shown that other-regarding concerns are weakened under risky situations. Daily experience also suggests that people care more about an identifiable than about an unidentifiable third person. We report on an experiment designed to explore whether rendering the other...

We report on an experiment designed to explore whether a written expression of disapproval affects future levels of cooperation. In between two identical public goods games, participants play a mini dictator game that, depending on the treatment, either gives or does not give the recipient the...

This paper derives and justifies a procedurally fair bidding mechanism and reviews experiments that apply the mechanism to public projects provision. In the experiments, not all parties benefit from provision, and the projects’ costs can be negative. The experimental results indicate that the...

Time-varying parameter techniques are commonly used to examine whether convergence in income has been a stable process. This article incorporates additional local features to a model studying 14 EU countries, thereby providing better estimates of the current state of the system when the relative...

Based on an axiomatically derived provision rule allowing community members to endogenously determine which, if any, public project should be provided, we perform experiments where (i) not all parties benefit from provision, and (ii) the projects' "costs" can be negative. In the tradition of...

We use experimental methods to study the power of leading by words. The context is a voluntary contribution mechanism with one-way communication. One group member can send a free-form text message to his fellow players. Contrary to the commonly accepted wisdom that the cooperation-enhancing...
