We test whether a descriptive norm-nudge is a suitable policy tool to increase cooperation in a social dilemma when decisions are taken by teams, not individuals. 10 Each team in our experiment comes from a different fishing boat at Lake Victoria, Tanzania. The provision of a norm-nudge is...

We present the results of a framed field experiment with Ethiopian farmers that use the mountain rain forest as a common pool resource. Harvesting honey causes damage to the forest, and open access leads to overharvesting. We test different mechanisms for mitigating excessive harvesting: a...

This article investigates economic performance when enforceable property rights are missing and subsistence needs matter. It shows that if per capita income is sufficiently high, a windfall gain in productivity triggers behavior that leads to higher growth (the normal reaction). The same shock...

This study experimentally investigates two possible reasons for cooperative investment decisions in common pool resource games with two players. One reason is strategic behavior: subjects, who are allowed to interact with their partners repeatedly, attempt to build a long-term relationship and...

We examine the role of support for coalition stability in common pool resource games such as fisheries games. Some players may not want to join a coalition that jointly manages a resource. Still, because they benefit from spillovers, they may want to support the coalition with a transfer payment...

This article investigates economic performance when enforceable property rights are missing and subsistence needs matter. It shows that if per capita income is sufficiently high, a windfall gain in productivity triggers behavior that leads to higher growth (the normal reaction). The same shock...

Common pool resources (CPRs) are usually exploited one generation after another - often overexploited - meaning there is an intergenerational link between the consumers - e.g., water for farming activities. This key dimension is often not considered in theoretical or field experiments, due to...

To limit global warming to 1.5°C, vast amounts of CO2 will have to be removed from the atmosphere via Carbon Dioxide Removal (CDR). Enhancing the CO2 sequestration of ecosystems will require not just one approach but a portfolio of CDR options, including so‐called nature‐based approaches...

Do individuals trained in law enforcement punish or reward differently from typical student subjects? We analyze norm enforcement behavior of newly appointed police commissioners in both a Voluntary Contribution Mechanism game and a Common Pool Resource game. Our experimental design includes...

We use a controlled laboratory experiment with and without overlapping generations to study the emergence of public debt. Public debt is chosen by popular vote, pays for public goods, and is repaid with general taxes. With a single generation, public debt is accumulated prudently, never leading...
