Recent survey data revealed that many California citrus growers did not know whether or not important beneficial insects were found on their fields while other growers were relying heavily or even entirely on these insects for pest control. Some pesticides are toxic both to the targeted pest and...

This paper presents a model of pest impacts in a multispecies framework. Strong detrimental relationships often form between pest populations and other biota, damaging ecosystem services and reducing social welfare. Under these circumstances, optimal pest management must account for the...

This paper examines how conservation decisions are affected by environmental degradation. Donations to an environmental NGO and participation in actual conservation activities capture individual preferences for environmental conservation. Environmental degradation is measured both through...

Eco-certification of coffee, timber and other high-value agricultural commodities is increasingly widespread. In principle, it can improve commodity producers' environmental performance, even in countries where state regulation is weak. But eco-certification will have limited environmental...

This paper presents a simple model of a common access fishery where fishermen care about relative performance as well as absolute profits. Our model captures the idea that status (which depends on relative performance) in a community influences a person's well-being. In our main specification,...

This paper analyzes the role of property rights in soil conservation. The conventional wisdom in soil conservation and property rights argues that tenants invest less than landlords in sustainable management practices and tend to overexploit soil biota services. The paper examines how this issue...

The way in which natural and physical capital are accumulated, distributed and harnessed underpins the functioning and sustainability of the productive system of each society as well as its social stratification. Significant changes in the interactions between natural and physical capital...

We present time-series tests of the quality of genuine savings and green net national income for predicting welfare changes. These tests check the validity of the theory of comprehensive national accounting, and more broadly of the theory of economic growth. The value of technological progress...

This paper studies whether pro-environmental consumption choices are consistent with utility maximization and what role the consumption behavior of reference persons and one's own past behavior play in this context. By combining data on individuals' pro-environmental consumption from a unique...

In this paper, we propose an alternative preference uncertainty measurement approach where respondents have the option to indicate their willingness to pay (WTP) for a nature protection program either as exact values or intervals from a payment card, depending on whether they are uncertain about...
