The BP Deepwater Horizon oil spill of 2010 has focused considerable attention on the potential liability and the operating conduct of big oil companies. This paper shows that limiting the ability of a company to insure and diversify its risks creates incentives to internalize the welfare effects of catastrophic events, leading to a welfare improvement. We model an economy with complete financia...

In coastal communities with uniform flood risk, amenity value is comprised of two components – view and access. Having controlled for view, it is assumed that any residual amenity value represents the benefit derived from households from accessing the beach for leisure or recreational purposes. However, as properties closer to the beach typically have improved viewsheds, the two amenities are h...

This research is located in Batang Mahat Lima Puluh Kota Regency, about 9.26 km2 from the narrowing location at Batu Kisok to upstream, prone flood. Due several flooding events Mahat, various assumptions and hypotheses have emerged regarding causes of flooding. analyses using Steady Flow simulation HEC-RAS 6.2 software. The result implies that two factors caused flood: (1) channel capacity insu...

Alginate based floating in situ gelling systems of famotidine (FIGF) were prepared by dissolving varying concentrations of alginate in deionized water containing sodium citrate, to which varying concentrations of drug and calcium chloride was added and dissolved by stirring. Results of preliminary trials indicate that concentrations of sodium alginate, calcium chloride and sodium citrate affect...

This paper provides a discussion of the principles of environmental taxation. It considers the empirical identification of environmental taxes and the problems associated with the choice of the right tax base from the point of view of the correction of market incentives. It then presents a model of optimal second best environmental taxation when taxes must fulfil the double role of modifying ma...

Dynamic partial adjustment models of residential electricity demand account for the fact that households may not adjust electricity consumption immediately in response to changes in prices, income, and other relevant factors, because of behavioral habits or adjustment costs for the capital stock of appliances. However, forward-looking behavior is generally neglected. Expectations about future p...

This paper explores the effect of airline emissions charges on airfares, airline service quality, aircraft design features, and network structure, using a detailed and realistic theoretical model of competing duopoly airlines. These impacts are derived by analyzing the effects of an increase in the effective price of fuel, which is the path by which emissions charges will alter airline choices....

This paper advocates computable general equilibrium (CGE) models as an analytical framework that is suitable for assessing the impacts of policy interference on the three dimensions of Sustainable Development, i.e. environmental quality, economic performance and equity. Methodological extensions of standard CGE models are illustrated that may strengthen the role of CGE models in measuring polic...

Pigs have become important animal models in voice research. Several objective parameters exist to characterize the pig voice, but it is not clear which of them are sensitive impaired quality after laryngeal injury or surgery. In order conduct meaningful research pigs, critical standard functional outcome measures that can distinguish between normal and voices. For this reason, we investigated 1...
