Weak disposability of outputs means that firms can abate harmful emissions by decreasing the activity level. Modeling weak disposability in nonparametric production analysis has caused some confusion. This paper identifies a dilemma in these approaches: conventional formulations implicitly and unintentionally assume all firms apply uniform abatement factors. However, it is usually cost efficien...

While there are extensive theoretical studies on firms’ responses to environmental regulations and enforcement, there are few empirical analyses of firms’ expenditures on pollution abatement in responding to different regulations and enforcement strategies. This paper presents an empirical analysis of pollution abatement efforts of Chinese industrial firms under a combination of pollution charg...

Global climate change presents a classic problem of decision making under uncertainty with learning. We provide stochastic dominance theorems that provide new insights into when abatement and investment into low carbon technology should increase in risk. We show that R&D into lowcarbon technologies and near-term abatement are in some sense opposites in terms of risk. Abatement provides insuranc...

Non-strategic firms with rational expectations make investment and emissions decisions. The investment rule depends on firms’ beliefs about future emissions policies. We compare emissions taxes and quotas when the (strategic) regulator and (nonstrategic) firms have asymmetric information about abatement costs, and all agents use Markov Perfect decision rules. Emissions taxes create a secondary ...

Current debates on mitigation emphasize the role of the inertia of the economic system. Our aim in this paper is to study in more depth how sectorally dif ferentiated inertia impacts on optimal CO2-emission abatement policies. Using the STARTS model, we show that optimal abatement levels and costs differ sensibly among sectors. Differential inertia is the critical determinant of this trade-off,...

People typically choose to live in quiet areas in order to safeguard their health and wellbeing. However, the benefits of living in quiet areas are relatively understudied compared to the burdens associated with living in noisy areas. Additionally, research is increasingly focusing on the relationship between the human response to noise and measures of health and wellbeing, complementing tradit...

A detailed assessment of the acoustic performance of several noise reduction concepts for aircraft flaps and landing gear is presented. Consideration is given to the best performing concepts within the suite of technologies that were evaluated in the NASA Langley Research Center 14by 22-Foot Subsonic Tunnel using an 18% scale, semi-span, high-fidelity Gulfstream aircraft model as a test bed. Mi...

Production activities exert a negative impact on the environment through emissions of pollutants. Environmental policies aim at the implementation of abatement technologies to reduce these emissions. Cost-effectiveness analysis is often applied as a tool to find abatement strategies that yield a certain emission reduction at minimum direct abatement cost to the producer concerned. The strength ...

This paper investigates the acoustic behavior of underwater air-filled resonators that could potentially be used in an underwater noise abatement system. The resonators are similar to Helmholtz resonators without a neck, consisting of underwater inverted air-filled cavities with combinations of rigid and elastic wall members, and they are intended to be fastened to a framework forming a station...
