Investment Incentives Under Emission Trading: An Experimental Study
This paper presents the results of an experimental investigation on incentives to adopt advanced abatement technology under emissions trading. Our experimental design mimics an industry with small asymmetric polluting firms regulated by different schemes of tradable permits. We consider three allocation/auction policies: auctioning off (costly) permits through an ascending clock auction, grandfathering permits with re-allocation through a single-unit double auction, and grandfathering with re-allocation through an ascending clock auction. Our results confirm both dynamic and static theoretical equivalence of auctioning and grandfathering. We nevertheless find that although the market institution used to reallocate permits does not impact the dynamic efficiency from investment, it affects the static efficiency from permit trading
Comparative quantification of health risks: Conceptual framework and methodological issues
Reliable and comparable analysis of risks to health is key for preventing disease and injury. Causal attribution of morbidity and mortality to risk factors has traditionally been conducted in the context of methodological traditions of individual risk factors, often in a limited number of settings, restricting comparability. In this paper, we discuss the conceptual and methodological issues for quantifying the population health effects of individual or groups of risk factors in various levels of causality using knowledge from different scientific disciplines. The issues include: comparing the burden of disease due to the observed exposure distribution in a population with the burden from a hypothetical distribution or series of distributions, rather than a single reference level such as non-exposed; considering the multiple stages in the causal network of interactions among risk factor(s) and disease outcome to allow making inferences about some combinations of risk factors for which epidemiological studies have not been conducted, including the joint effects of multiple risk factors; calculating the health loss due to risk factor(s) as a time-indexed "stream" of disease burden due to a time-indexed "stream" of exposure, including consideration of discounting; and the sources of uncertainty
Maximising the retained value of product recovery based on circular economy principles
Previous environmental studies indicate several barriers to circular economy and material efficiency including a lack of detailed methodologies for manufacturing improvement in terms of environmental and operational performances to measure, monitor and evaluate material consumption and waste generation. A lean and green tool, the green performance map (GPM), is an appropriate tool for different environmental initiatives including training, improvement, reporting and development. Through literature review and multiple case study methodology, this chapter presents the current application of GPM in industry and its usage to regularly measure and monitor material efficiency measurements on different levels and to remove barriers to improved material efficiency
