In the second half of the twentieth century, worldwide attitudes toward whaling shifted from widespread acceptance to moral censure. Why? Whaling, once as important to the global economy as oil is now, had long been uneconomical. Major species were long known to be endangered. Yet nations had...

The contribution of each municipality to the environmental state of the country is outlined, concerning the following components: surface water, air and waste. Integral values are calculated and through the taxonomic approach all municipalities are ranged according to their distance from a...

A model of different species competing for the same environment is presented, and possible explanations of peaceful coexistence or rather internecine conflicts are consequently derived. By means of a Lotka-Volterra dynamic system we describe the evolution of two populations (bees and locusts)...

Water management provides a critical lens onto the development process. For the last several centuries, improvements in clean water and sanitation have contributed to better health and increased life expectancies. Currently, however, developing countries seem unable to make much progress in...

A feature of recent policy discussion both in Australia and overseas has been a heightened interest in energy taxes and fuel taxes of various kinds. These taxes have been advocated on various grounds, notably their role in discouraging greenhouse gas emissions. At the same time, at least in...

This paper presents estimates of short-run sectoral and economy-wide effects of the introduction of a carbon tax in Australia. The results are derived using an enhanced version of the ORANI multi-sectoral model of the Australian economy. We simulate the introduction of a carbon tax at a rate of...

This study uses hedonic analysis to estimate the effects of a common aquatic invasive species—Eurasian watermilfoil (milfoil)—on property values across an extensive system of over 170 lakes in the northern forest region of Wisconsin. Since milfoil is inadvertently spread by recreational...

Many studies on individual decision making have shown that a disproportionate number of respondents choose the status quo (SQ) alternative. But it is still unclear what motivates individuals to disproportionately select the SQ alternative. Using data from two choice experiments about forest...

Using data from what was once one of the world’s largest capture fisheries, the northern cod fishery, the economic value of a marine reserve is calculated using a stochastic optimal control model with a jump-diffusion process. Counterfactual analysis shows that with a stochastic environment an...
