When new tradable fishing allowance markets are established, they are often accompanied by a period of high price volatility. These fluctuations play a significant role in determining the outcomes for the traders involved, and for the investment decisions that allowance holders make when using noisy price signals. This paper reports an evaluation of two market design features that may reduce vo...

This study explores the differences in pollution control performances of industrial enterprises with various ownerships in China – State owned (SOE), collectively or community owned (COE), privately owned (POE), foreign directly invested (FDI) companies as well as joint ventures. A survey was conducted of approximately 1000 industrial firms in three provinces in China, which collects the detail...

The sensitivity of the optimal control of carbon dioxide emissions to the specification of the social welfare function is systematically explored using the FUND model. Increasing risk aversion emphasises climate change damages relative to emission reduction costs, but at the same time increases the discount rate of consumption. Without international co-operation, the discount rate effect domina...

Routine cytogenetic investigations of the Chianina cattle (BTA) breed revealed the presence of longer and smaller chromosomes than the largest (BTA1) and smallest (BTA29) chromosomes in the cells of a young, normal-looking bull used for reproduction. Application of both RBA-banding and Ag-NOR techniques, as well as the use of the FISH technique and specific molecular markers of both BTA11 (IL1B...

Over the last three decades, ambient concentrations of sulfur dioxide (SO2) air pollution have declined by approximately 80%. This paper tests whether the 1970 Clean Air Act and its subsequent amendments caused this decline. The centerpiece of this legislation is the annual assignment of all counties to SO2 nonattainment or attainment categories. Polluters face stricter regulations in nonattain...

We report two patients whose karyotype revealed an additional segment 1q inserted into an inverted chromosome 4. The patients were partially trisomic for the region 1q24----1q41, karyotype 46,XY or XX, inv ins(4;1)inv(4)(q28;q24q41)(p15 . 3q28), while in the mother the chromosomal aberration was balanced. The inserted segment was inverted. In six patients from three other families with insertio...

This paper examines and quantifies the complex linkages between industrial activity, environmental regulations and air pollution in China. We utilize a little used dataset of Chinese industry specific emissions for a variety of pollutants between 1996 and 2003. Our analysis allows us to investigate the role played by different determinants of emissions intensity. We find pollution intensity to ...
