Climate Change in a Public Goods Game: Investment Decision in Mitigation versus Adaptation

Submitted by admin on

The authors studied the potential tradeoff between countries’ investments in mitigation versus adaptation to climate change. Mitigating greenhouse gases may be a public good, but adaptation to climate change is a private good, benefiting only the country or individual.

Changes in discount rates over time: Evidence from Ethiopia

Submitted by admin on

Numerous experimental studies have lent credence to the hyperbolic discounting model, which posits that individuals are impatient about immediate or near-term consumption decisions, but are relatively more patient over future consumption.

Social Background, Cooperative Behavior, and Norm Enforcement

Submitted by admin on

Studies have shown differences in cooperative behavior across countries and in the use of (and reaction to) a norm enforcement mechanism in cross-cultural studies.

 

The authors present data that prove that stark differences in both dimensions can exist even within the same town. They created a unique data set, based on one-shot public goods experiments in South Africa. Most of the group differences can be explained by variables for social capital and social environment, such as trust or household violence.

Enforcement of Exogenous Environmental Regulations, Social Disapproval, and Bribery

Submitted by admin on

Many resource users are not involved in formulating and enforcement of resource management regulations in developing countries and do not generally accept such rules. Enforcement officers who have social ties to resource users may encounter social disapproval if they enforce regulations zealously, so they may accept bribes to avoid it.

Conditional Cooperation and Social Group: Experimental Results from Colombia

Submitted by admin on

There is growing interest in understanding whether behavior is the same across locations. By holding cross- and within-country dimensions constant (in contrast to previous studies on cross-group comparisons of conditional cooperation), the authors investigated cooperative behavior between social groups in the same location. Their results reveal significantly different cooperation behavior, suggesting that different social groups exhibit differences both in terms of composition of types and extent of conditional cooperation.

Risk Aversion and Expected Utility of Consumption over Time

Submitted by admin on

The calibration theorem by Rabin (2000) implies that seemingly plausible smallstake choices under risk imply implausible large-stake risk aversion. This theorem is derived based on the expected utility of wealth model. However, Cox and Sadiraj (2006) show that such implications do not follow from the expected utility of income model. One may then wonder about the implications for more applied consumption analysis.
