The paper provides an integrated framework to assess water markets in terms of their institutional underpinnings and the three 'pillars' of integrated water resource management: economic efficiency, equity and environmental sustainability. This framework can be used: (1) to benchmark different...

Greater historical perspective is needed to enlighten current debate about future human responses to higher temperatures and increased precipitation variation. We analyze the impact of climatic conditions and variability on agricultural production in five semi-arid western states. We assemble...

Fresh water supplies increasingly are under stress in many parts of the world due to rising populations, higher per capita incomes and corresponding consumption, greater environmental concerns, and the effects of climate change. Water rights and markets are part of the institutional menus for...

In a paper presented to the Royal Meteorological Society, Brodie (1905) presented a data series that presaged the modern Environmental Kuznets Curve: in the decades leading up to 1890, the number of foggy days in London rose steadily, but after 1891, the fogs began to subside. Brodie attributed...

We exploit regional variation in suitability for cultivating potatoes, together with time variation arising from their introduction to the Old World from the Americas, to estimate the impact of potatoes on Old World population and urbanization. Our results show that the introduction of the...

This paper uses an updated and revised panel data set on ambient air pollution in cities world-wide to examine the robustness of the evidence for the existence of an inverted U-shaped relationship between national income and pollution. We test the sensitivity of the pollution-income relationship...

In many societies, social norms create common property rights in natural resources, limiting incentives for private investment. This paper uses a randomized evaluation in Kenya to measure the health impacts of investments to improve source water quality through spring protection, estimate the...

It is conventional wisdom that it is possible to reduce exposure to indoor air pollution, improve health outcomes, and decrease greenhouse gas emissions in the rural areas of developing countries through the adoption of improved cooking stoves. This belief is largely supported by observational...

We consider a general class of nonlinear optimal policy problems involving forward-looking constraints (such as the Euler equations that are typically present as structural equations in DSGE models), and show that it is possible, under regularity conditions that are straightforward to check, to...

We implement a dynamic programming algorithm on a computational grid consisting of loosely coupled processors, possibly including clusters and individual workstations. The grid changes dynamically during the computation, as processors enter and leave the pool of workstations. The algorithm is...
