00-05 "Getting the Prices Wrong: The Limits of Market-Based Environmental Policy."
No full textMarket based policies are fast becoming the recommended policy panacea for all the world's environmental problems. Implicit in such recommendations is the theory that free markets, adjusted for externalities, can always create an "efficient" allocation of society's resources. As a result, many contemporary policymakers advocate rolling back regulations in order to let the market protect the environment. There is a fundamental distinction between the use of the market as a tool to help achieve society's goals, and as a blueprint for society's goals; the market is a reasonable policy tool but not a reasonable blueprint. The market as blueprint fails because there are significant public purposes that cannot be achieved by prices and markets alone. Five major arguments show that getting the prices right is often a narrow or meaningless objective; society may intentionally and appropriately choose to "get the prices wrong" in order to pursue more important goals.
05-05 "Teaching Ecological and Feminist Economics in the Principles Course"
No full textIt can be difficult to incorporate ecological and feminist concerns into introductory courses based on neoclassical analysis. We have faced these issues head-on as we have worked on writing introductory economics textbooks, Microeconomics in Context (Goodwin, Nelson, Ackerman and Weisskopf, 2005) and Macroeconomics in Context (in progress). In this essay, we will describe how we have modified the introductory curriculum to encompass these perspectives.
Onboard computing in forest machinery - A perspective from Australia and South Africa
No full textInternational research has demonstrated gains of up to 30% in improving utilization and productivity of
forest harvesting machinery through the use of onboard computers. However, use of onboard computing
is very much in its infancy in Australia and South Africa primarily due to lack of local experience in their
use.
Trials covering a range of onboard computers, forest machinery and forest types were conducted in
Australia and South Africa to study their use under local conditions. The results are being used in these
countries to promote the benefits and uptake of onboard computers. In Australia, this has been facilitated
through an online selection guide to assist in determining suitable onboard computers. In South Africa,
onboard computing research is aimed at identifying operational factors in primary and secondary
transport, which have significant impacts on production and utilization of applied equipment.
The presentation briefly describes the trials highlighting what worked and what didn’t work and then
brings together common findings and lessons learnt

06-05 Can Climate Change Save Lives? A comment on “Economy-wide estimates of the implications of climate change: Human health”
No full textIn a recent article in this journal, Francesco Bosello, Roberto Roson, and Richard Tol make the surprising prediction that the first stages of global warming will, on balance, save a large number of lives. Bosello et al. fail to substantiate this remarkable estimate, and they make multiple mistaken or misleading assumptions. They rely on research that identifies a simple empirical relationship between temperature and mortality, but ignores the countervailing effect of human adaptation to gradual changes in average temperature. While focusing on small changes in average temperatures, they ignore the important health impacts of extreme weather events such as heat waves, droughts, floods, and hurricanes. They extrapolate this pattern far beyond the level that is apparently supported by their principal sources, and introduce an arbitrary assumption that may bias the result toward finding benefits from warming.

06-02 "The Unbearable Lightness of Regulatory Costs"
No full textWill unbearable regulatory costs ruin the US economy? This specter haunts official Washington, just as fears of communism once did. Once again, the prevailing rhetoric suggests, an implacable enemy of free enterprise puts our prosperity at risk. Like anti-communism in its heyday, anti-command-and-control-ism serves to narrow debate,promoting the unregulated laissez-faire economy as the sole acceptable goal and standard for public policy. Fears of the purported costs of regulation have been used to justify a sweeping reorganization of regulatory practice, in which the Office of Management and Budget (OMB) is empowered to, and often enough does, reject regulations from other agencies on the basis of intricate, conjectural, economic calculations. This article argues for a different perspective: what is remarkable about regulatory costs is not their heavy economic burden, but rather their lightness. Section 1 identifies two general reasons to doubt that there is a significant trade-off between prosperity and regulation: first, regulatory costs are frequently too small to matter; and second, even when the costs are larger, reducing them would not always improve economic outcomes. The next three sections examine evidence on the size and impact of regulatory costs. Section 2 presents cost estimates for a particularly ambitious and demanding environmental regulation, REACH -- the European Union's new chemicals policy. Section 3 discusses academic research on the "pollution haven" hypothesis, i.e. the assertion that firms move to developing countries in search of looser environmental regulations. Section 4 reviews the literature on ex ante overestimation of regulatory costs, including the recent claims by OMB that costs are more often underestimated (and/or benefits overestimated) in advance. Turning to the economic context, Section 5 explains why macroeconomic constraints may eliminate any anticipated economic gains from deregulation. Section 6 introduces a further economic argument against welfare gains from deregulation, based on the surprising evidence that unemployment decreases mortality. Section 7 briefly concludes.

03-09 "Costs of Preventable Childhood Illness: The Price We Pay for Pollution "
No full textA growing body of scientific literature implicates toxic exposures in childhood illnesses and developmental disorders. When these illnesses and disabilities result from environmental factors under human control, they can and should be prevented. This report documents monetary costs associated with five major areas of health problems in children that have been linked to preventable environmental exposures: cancer, asthma, lead poisoning, neurobehavioral disorders, and birth defects. We review incidence and prevalence estimates for these disorders, as well as estimates of the associated monetary costs. We apply the concept of the “environmentally attributable fraction” (EAF) of an illness, where EAF is the estimated percentage of cases of an illness that result from an environmental exposure. Preventable childhood illnesses and disabilities attributable to environmental factors are associated with large monetary costs. Our estimate of direct and indirect costs ranges from 1.6 billion annually in Massachusetts. Of course, there is no dollar measure of the full practical and emotional burden borne by these children, their families, and the communities in which they live.
