This study aims to investigate the concentration levels, pollution characteristics and the associated potential ecological risks of the heavy metals found in dust in the metropolitan area of Beijing, China during the winter. Dust samples were collected at 49 different spatial locations of Beijing's metropolitan area from November 2013 to January 2014, in which the concentration levels of Cd, Cr...

This paper examines several policy regimes to deal with the problem that households suffer from environmental damage by firms in the same region. Taxation gives firms and households an incentive to stay away from each other. Laissez faire (compensation) only gives households (firms) an incentive to stay away from firms (households). We employ an evolutionary framework to analyze migration movem...

This paper uses a nearest neighbor matching estimator to examine the effects of an emissions trading program. An important perceived advantage of “cap-and-trade” programs over more traditional, more prescriptive forms of regulation is that enhanced compliance flexibility and cost effectiveness can make more stringent emissions reductions politically feasible. A potential disadvantage is that a ...

Polymer electrolyte fuel cells (PEFCs) have attracted much interest due to the need for an efficient, non-polluting power source with high energy density for vehicles in urban environments, as well as portable electronics [...].

a r t i c l e i n f o This paper develops an endogenous growth model to study the decentralized equilibrium and the optimum conditions in an economy which uses polluting resources. The model includes two policy instruments, a subsidy to final consumption and an emissions tax. It also considers two forms of endogenous technical change, pollution-reducing knowledge and horizontal innovation. We s...
