With data from framed common pool resource experiments conducted with artisanal fishing communities in Colombia, we estimate a hierarchical linear model to investigate within-group and between-group variation in individual harvest strategies across several institutions. Our results suggest that communication serves to effectively coordinate individual strategies within groups, but that these coordinated strategies vary considerably across groups. In contrast, weakly enforced regulatory restrictions on individual harvests (as well as unregulated open access) produce significant variation in the individual strategies within groups, but these strategies are roughly replicated across groups so that there is little between-group variation. |

Theoretical analyses of international environmental agreements (IEAs) have typically employed the concept of self-enforcing agreements to predict the number of parties to such an agreement. The term self-enforcing, however, is a bit misleading. The concept refers to the stability of cooperative agreements, not to enforcing these agreements once they are in place. Most analyses of IEAs simply ignore the issue of enforcing compliance by parties to the terms of an agreement. In this paper we analyze an IEA game in which parties to an agreement finance an independent enforcement body with the power to monitor the parties' compliance to the terms of the IEA and impose penalties in cases of noncompliance. This approach is broadly consistent with the... |

Homeland security against possible terrorist attacks involves making decisions under true uncertainty. Not only are we ignorant of the form, place, and time of potential terrorist attacks, we are also largely ignorant of the likelihood of these attacks. In this paper, we conceptualize homeland security under true uncertainty as society's immunity to unacceptable losses. We illustrate and analyze the consequences of this notion of security with a simple model of allocating a fixed budget for homeland security to defending the pathways through which a terrorist may launch an attack and to mitigating the damage from an attack that evades this defense. In this problem, immunity is the range of uncertainty about the likelihood of an attack within which the... |

Conventional wisdom among environmental economists is that the relative slopes of the marginal social benefit and marginal social cost functions determine whether a price-based or quantity-based environmental regulation leads to higher expected social welfare. We revisit the choice between price-based vs. quantity-based environmental regulation under Knightian uncertainty; that is, when uncertainty cannot be modeled with known probability distributions. Under these circumstances, the policy objective cannot be to maximize the expected net benefits of emissions control. Instead, we evaluate an emissions tax and an aggregate abatement standard in terms of maximizing the range of uncertainty under which the welfare loss from error in the estimates of the... |

This paper examines the effects of risk aversion on compliance choices in markets for pollution control. A firm's decision to be compliant or not is independent of its manager's risk preference. However, noncompliant firms with risk averse managers will have lower violations than otherwise identical firms with risk neutral managers. The violations of noncompliant firms with risk averse managers are independent of differences in their benefits from emissions and their initial allocations of permits if and only if their managers' utility functions exhibit constant absolute risk aversion. However, firm-level characteristics do impact violation choices when managers have coefficients of absolute risk aversion that are increasing or decreasing in profit levels.... |

This paper develops and tests several models of pure Nash strategies of individuals who extract from a common pool resource when they are motivated by a combination of self-interest and other motivations such as altruism, reciprocity, inequity aversion and conformism. We test whether an econometric summary of subjects' strategies is consistent with one of these motivations using data from a series of common pool resource experiments conducted in three regions of Colombia. As expected, average extraction levels are less than that predicted by a model of pure self-interest, but are nevertheless sub-optimal. Moreover, we find that a model of conformism with monotonically increasing best response functions best describes average strategies. Our empirical... |

Since firms in an emissions trading program are linked together through a permit market, so too are their compliance choices. Thus, enforcement strategies for trading programs must account for not only the direct effects of enforcement on compliance and emissions decisions, but also the indirect effects that occur because changes in enforcement can induce changes in permit prices. This paper uses laboratory experiments to test for these direct and indirect market effects. Consistent with theoretical predictions, we find a direct effect of enforcement on individual violations, as well as a countervailing market effect through the permit price. Thus, the productivity of increased enforcement pressure to reduce noncompliance is partially offset by a... |
