Management of Hazardous Waste and Contaminated Land

Regulation of hazardous waste and cleanup of contaminated sites are two major components of modern public policy for environmental protection. We review the literature on these related areas, with emphasis on empirical analyses. Researchers have identified many behavioral responses to regulation of hazardous waste, including changes in the location of economic activity. However, the drivers behind compliance with these costly regulations remain a puzzle, as most research suggests a limited role for conventional enforcement. Increasingly sophisticated research examines the benefits of cleanup of contaminated sites, yet controversy remains about whether the benefits of cleanup in the U.S. exceed its costs. Finally, research focusing on the imposition of legal liability for damages from hazardous waste finds advantages and disadvantages of the U.S. reliance on legal liability to pay for cleanup, as opposed to the government-financed approaches more common in Europe

Global Increase in Climate-Related Disasters

Intense climate-related disasters - floods, storms, droughts, and heat waves - have been on the rise worldwide. At the same time and coupled with an increasing concentration of greenhouse gases in the atmosphere, temperatures, on average, have been rising, and are becoming more variable and more extreme. Rainfall has also been more variable and more extreme. Is there an ominous link between the global increase of these hydrometeorological and climatological events on the one side and anthropogenic climate change on the other? This paper considers three main disaster risk factors - rising population exposure, greater population vulnerability, and increasing climate-related hazards - behind the increased frequency of intense climate-related natural disasters. In a regression analysis within a model of disaster risk determination for 1971-2013, population exposure measured by population density and people's vulnerability measured by socioeconomic variables are positively linked to the frequency of these intense disasters. Importantly, the results show that precipitation deviations are positively related to hydrometeorological events, while temperature and precipitation deviations have a negative association with climatological events. Moreover, global climate change indicators show positive and highly significant effects. Along with the scientific association between greenhouse gases and the changes in the climate, the findings in this paper suggest a connection between the increasing number of natural disasters and man-made emissions of greenhouse gases in the atmosphere. The implication is that climate mitigation and climate adaptation should form part of actions for disaster risk reduction

Relationship Between Trade, Investment and Environment: A Review of Issues

The inter-linkage between economic openness and environmental repercussions is a widely researched area. The current study contributes in the existing pool of research by conducting a cross-country empirical analysis for the year 2008 by exploring the interrelationship between openness indicators (trade and investment) and environmental performance of a country. For this purpose, the analysis separately considers export orientation, import orientation, FDI inwardness and FDI outwardness of the countries in different variations of the proposed empirical model. The regression results do not provide strong support to the Pollution Haven Hypothesis (PHH). The findings also confirm a relationship between socio-economic and socio-political factors in a country and its environmental performance

The economics of natural disasters

This review discusses the ways in which countries are affected by natural disasters, depending on their socioeconomic characteristics, their level of development, and their inherent levels of natural disaster risk. We also explore various aspects of ex ante disaster mitigation such as improvements in natural disaster risk information and natural disaster insurance markets, as well as ex post responses to natural disaster in the form of postdisaster aid and long-run growth prospects. By highlighting some of the recent findings in this literature, we synthesize what we know about the economics of natural disasters and identify research areas of interest for future work. </jats:p

The trade of polyethylene waste: prices or policies?

We contribute to the theoretical and empirical literature on waste trade, with a focus on the secondhand market of plastic materials. To do this, we take two main steps: we first model a two-country setting with an exporting and an importing country, to derive testable predictions on how their main economic, policy and institutional features are expected to affect waste flows across countries. Then, we rely on a negative binomial regression model to test our theoretical results using data on international trade of polyethylene waste. Empirical results do not reject theoretical predictions, although some exceptions arise. A first striking result is that exporting prices do not seem to matter in export flows. Also, relying more on landfilling and recycling negatively affects exports, suggesting complex interactions among waste management and export patterns. Finally, we conclude that legal rights enforcement in exporting countries does not affect waste trade. A ‘‘pollution haven’’ hypothesis is however indirectly suggested by the negative link between wages in the importing countries and the amount of exported waste
