Within and Between Group Variation of Individual Strategies in Common Pool Resources: Evidence from Field Experiments AgEcon
Velez, Maria Alejandra; Murphy, James J.; Stranlund, John K..
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.

Enforcing 'Self-Enforcing' International Environmental Agreements AgEcon
McEvoy, David M.; Stranlund, John K..
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...

On the Production of Homeland Security Under True Uncertainty AgEcon
Stranlund, John K.; Field, Barry C..
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...

Price-Based vs. Quantity-Based Environmental Regulation under Knightian Uncertainty: An Info-Gap Robust Satisficing Perspective AgEcon
Stranlund, John K.; Ben-Haim, Yakov.
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...

Risk Aversion and Compliance in Markets for Pollution Control AgEcon
Stranlund, John K..
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....

The Problem of Maintaining Compliance within Stable Coalitions: Experimental Evidence AgEcon
McEvoy, David M.; Murphy, James J.; Spraggon, John M.; Stranlund, John K..
This study examines the performance of stable cooperative coalitions that form to provide a public good when coalition members have the opportunity to not comply with their commitments. A stable coalition is one in which no member wishes to leave and no non-member wishes to join. To counteract the incentive to violate their commitments, coalition members fund a third-party enforcer. This leads to the theoretical conclusion that stable coalitions are larger (and provide more of a public good) when their members must finance enforcement relative to when compliance is ensured without the need for costly enforcement. However, our experiments reveal that giving coalition members the opportunity to violate their commitments while requiring them to finance...

What Motivates Common Pool Resource Users? Experimental Evidence from the Field AgEcon
Velez, Maria Alejandra; Stranlund, John K.; Murphy, James J..
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...

DIRECT AND MARKET EFFECTS OF ENFORCING EMISSIONS TRADING PROGRAMS: AN EXPERIMENTAL ANALYSIS AgEcon
Murphy, James J.; Stranlund, John K..
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...

A Note on Emissions Taxes and Incomplete Information AgEcon
Chavez, Carlos A.; Stranlund, John K..
In contrast with what we perceive is the conventional wisdom about setting emissions taxes under uncertainty, we demonstrate that setting a uniform tax equal to expected marginal damage is not generally efficient under incomplete information about firms’ abatement costs and damages from pollution. We show that efficient taxes will deviate from expected marginal damage if there is uncertainty about the slopes of the marginal abatement costs of regulated firms. Moreover, efficient emissions tax rates will vary across firms if a regulator can use observable firm-level characteristics to gain some information about how the firms’ marginal abatement costs vary.

Who Should Bear the Administrative Costs of an Emissions Tax? AgEcon
Stranlund, John K.; Chavez, Carlos A..
All environmental policies involve administrative costs, the costs of implementing and managing policies that extend beyond abatement costs. We examine theoretically the optimal distribution of these costs between the public and regulated sources of pollution. The distribution of administrative costs affects social welfare only if public funds are more expensive than private funds, or if the distribution of administrative costs affects the size of a regulated industry. If having the public take on a larger part of administrative costs increases the size of the industry and this does not lead to lower emissions for a given emissions tax, then it is optimal to make the pollution sources bear all of the administrative costs. A necessary, but not sufficient,...

Does Government Regulation Complement Existing Community Efforts to Support Cooperation? Evidence from Field Experiments in Colombia AgEcon
Lopez, Maria Claudia; Murphy, James J.; Spraggon, John M.; Stranlund, John K..
In this paper we describe a field experiment conducted among mollusk harvesters in a community on the Pacific Coast of Columbia. The experiment is based on a standard linear public good and consists of two stages. In the first stage we compare the ability of monetary and nonmonetary sanctions among community members to increase contributions to the public good. In the second stage we add a government regulation with either a high or low sanction for noncompliance to community enforcement efforts. The results for the first stage are consistent with other comparisons of monetary and nonmonetary sanctions within groups; both led to higher contributions. The results from the second stage reveal that government regulations always complemented community...
