Among the ethical objections to intergenerational impartiality is the violation of consumer sovereignty given that individuals are impatient. We accommodate that concern by distinguishing intra- and inter-generational discounting in an OLG model suitable for analyzing sustainability issues....

A theory of payment for ecosystem services (PES) pricing consistent with dynamic efficiency and sustainable income requires optimized shadow prices. Since ecosystem services are generally interdependent, this requires joint optimization across multiple resource stocks. We develop such a theory...

Demand for water will continue to increase as per capita income rises and the population grows, and climate change can exacerbate the problem through changes in precipitation patterns and quantities, evapotranspiration, and land cover—all of which directly or indirectly affect the amount of...

Optimal sequencing of resource extraction is typically studied for nonrenewable resources. We provide conditions for optimal use of multiple sources of a renewable resource and characterize the resulting extraction sequence, resource scarcity values, and (single) efficiency price path for two...

With climate change exacerbating over-exploitation, groundwater scarcity looms as an increasingly critical issue worldwide. Minimizing the adverse effects of scarcity requires optimal as well as sustainable patterns of groundwater management. We review the many sustainable paths for groundwater...

We show that Stiglitz's (1974) principal-agency theory of share tenancy does not imply, as alleged, that the optimal tenant share is less than one for risk-averse tenants nor that the share decreases monotonically with tenant risk aversion. Tenants may self insure by working harder increasingly...

We assess the development economics of on-farm employment with an eye toward policy implications. What do we know and what additional research is needed? The older tradition of labor market dualism and some of the more modern research are seen to share a characteristic of misplaced exogeneity,...

To meet the growing demand for freshwater, many regions have increased pumping of groundwater in recent years, resulting in declining groundwater levels worldwide. A promising development is technical change regarding groundwater substitutes such as desalination and wastewater recycling....

General principles of groundwater management for a single aquifer are extended to the management of multiple water resources, including additional aquifers, recycled wastewater, and desalinated seawater. Optimal groundwater extraction can be incentivized by pricing according to the Pearce...
