The Earth's ecosystems provide myriad goods and services that are essential to human wellbeing. This paper offers a typology of ecosystem services that emphasizes the means by which humans experience the service rendered. The typology distinguishes between services that are directly experienced,...

This paper presents an empirical study of population growth and environmental change using cross-sectional district-level data from South, Central and West India. Environmental change is measured using a satellite-based "greenness" index. Unlike prior work, the analysis treats population and...

Agricultural nitrogen losses are the major contributor to nitrogen loads in the Mississippi River, and consequently, to the existence of a hypoxic, or "dead", zone in the Gulf of Mexico. Focusing on two small agricultural watersheds in southwestern Minnesota, simulation results from the...

This research explores the welfare consequences of substituting carbon taxes for conventional distortionary taxes in a small open economy, using Pennsylvania as case study. A computable general equilibrium (CGE) model is developed for Pennsylvania to simulate possible outcomes when carbon taxes...

We consider a model of regulation for nonpoint source water pollution through non linear taxation/subsidization of agricultural production. Farmers are heterogenous along two dimensions, their ability to transform inputs into final production and the available area they possess. Asymmetric...

The regulation of nonpoint source water pollution from agriculture is a complex problem characterized by a multiplicity of polluters, informational asymmetries, complex fate and transport processes, and stochastic environmental factors. Taken together, these characteristics make regulatory...

The goal of this experimental study was to test an effectiveness of a group contract designed to control nonpoint source water pollution from farms' runoff (Pushkarskaya 2003). In particular, the regulator pays for pollution reduction credits earned by the group of the farmers, who voluntary...

Funds available to purchase land and easements for conservation purposes are limited. This article provides a targeting strategy for protecting multiple environmental benefits that includes heterogeneity in land costs and probability of land-use conversion, by incorporating spatially explicit...

The study proposes a discrete-choice model for environmental policy/program valuation, to be used in cases when several policies are valued sequentially. The stochastic specification of the model is consistent with the transitivity and continuity axioms of utility analysis. An empirical...
