We examine in an experiment whether a solemn oath to cooperation mediates defection in a prisoners’ dilemma among those making a commitment and those whom the commitment is being made to. We explore which of the two internal drivers of behavior, preferences or beliefs, is activated to promote...

Compensation schemes in which land owners receive payments for voluntarily managing their land in a biodiversity-enhancing manner have become one of the most important instruments for biodiversity conservation worldwide. One key challenge when designing such schemes is to account for the spatial...

This paper develops a general equilibrium model to measure welfare effects of taxes for correcting environmental externalities caused by domestic trade, focusing on exter- nalities that arise through exports. Externalities from exports come from a number of sources. Domestically owned ships,...

We examine consumer certainty of future preferences and overconfidence in predicting future preferences. We explore how preference certainty and overconfidence impact the option value to revise today's decisions in the future. We design a laboratory experiment that creates a controlled choice...

While becoming a parent is transformational as one focuses more on the future, the time constraints are more binding right now. Using a unique data set that allows us to compare CO2 emissions from Swedish two-adult households with and without children, we find becoming a Swedish parent causes a...

We examine the causes and policy consequences of strategic (willful) ignorance of risk as an excuse to overengage in risky health behavior. In an experiment on Copenhagen adults, we allow subjects to choose whether to learn the calorie content of a meal before consuming it, and measure their...

We report the findings of a unique nation-wide experiment to price access to our public lands. In 2004, the U.S. Federal Lands Recreation Enhancement Act mandated the creation of a new annual pass to cover all federal recreation sites that charge an entrance or access fee. Our task was to assist...

Herein we model the widespread dispersal and management of an invasive species as a weak-link public good. The risk of introduction is driven in part by economic activity, is influenced by policies directed at the risk, and economic activity responds/adapts to the risk. Framed around recent...

The Theory of the Second Best implies that any country with less-than-ideal resources can lose from international trade. Recently it has been suggested this means the South (poor countries) are better off suppressing trade with the North, especially trade in natural resource products, since the...
