Policies to address environmental and natural resource management are often implemented at the group level. The defining feature of such policies is that penalties or rewards are based on group rather than individual performance, or rights are allocated to a group rather than to individuals....

Many of the most pernicious economic institutions and policies create entry barriers or manipulate factor prices to transfer resources from entrepreneurs and workers to groups that hold political power. These inefficiencies partly result from the fact that direct and efficient fiscal instruments...

We study how the strength of property rights to individual extractive firms affects a regulator's choice over exploitation rates for a natural resource. The regulator is modeled as an intermediary between current and future resource harvesters, rather than between producers and consumers, as in...

Property rights are commonly touted as a solution to common pool resource problems. But in practice the security of these property rights varies substantially owing to differences in design. In fisheries, the design of individual transferable quotas (ITQs) varies widely; the consequences of...

How does the sustainable level of consumption depend on productivity growth and the size and growth rate of the population? What is the effect of uncertainty over these growth rates? I address these questions using a model in which productivity and population growth are stochastic, and social...

This paper develops a new approach to make welfare assessments based on the notion of Dynamic Stochastic weights (DS-weights for short). For a large class of dynamic stochastic economies with heterogeneous individuals, we introduce an aggregate additive decomposition that satisfies desirable...

We consider the optimal policy problem of a benevolent planner, who is uncertain about an individual's true preferences because of inconsistencies in revealed preferences across behavioral frames. We adapt theories of expected utility maximization and ambiguity aversion to characterize the...

Collective action is a dynamic process where individuals in a group assess over time the benefits and costs of participating toward the success of a collective goal. Early participation improves the expectation of success and thus stimulates the subsequent participation of other individuals who...
