This paper establishes an agent-based simulation system of the carbon emissions trading in accordance with the complex feature of the trading process. This system analyzes the impact of the carbon quota allocation mechanism on emissions trading for three different aspects including the amount of emissions reduction, the economic effect on the emitters, and the emissions reduction cost. Based on...

In sea cage fish farming, production quotas aim to constrain the impact of fish farming on the surrounding ecosystem. It is unknown how these quotas affect economic profitability and environmental impact of genetic improvement. We combined bioeconomic modelling with life cycle assessment (LCA) to calculate the economic (EV) and environmental (ENV) values of thermal growth coefficient (TGC) and ...

This paper develops a continuous-time two-sector model to study the economic e ects of an import quota during the period of time over which it is imposed. One of the sectors is protected by a quota, which in our setup manifests itself as an integral constraint on the ow of imports of the protected commodity. In sharp contrast to the existing literature, our small open economy exhibits distinctl...

In parliaments elected by proportional systems the seats are allocated to the political parties roughly proportionally to the shares of votes for the party lists obtained in elections. Assuming that members of the parliament representing the same party are voting together, it has sense to require that distribution of the influence of the parties in parliamentary decision making is proportional ...

Weighted voting games model decision-making bodies where decisions are made by a majority vote. In such games, each agent has a weight, and a coalition of agents wins the game if the sum of the weights of its members exceeds a certain quota. The Shapley value is used as an index for the true power held by the agents in such games. Earlier work has studied the implications of setting the value o...

objective: water scarcity is a growing global problem and increasing population pressures, living standards and the growing demand for environmental quality have evoked all the governments to represent better solutions about water resources management. in addition, there are growing political ties for reducing water use in agriculture that follow enough environmental benefits and increase the w...

BACKGROUND Interaction in clinical trials presents challenges for design and appropriate sample size estimation. Here we considered interaction between treatment assignment and a dichotomous prognostic factor with a continuous outcome. Our objectives were to describe differences in power and sample size requirements across alternative distributions of a prognostic factor and magnitudes of the i...

Policy-makers targeting reduction in greenhouse gas (GHG) emissions have a variety of instruments at their disposal (emission taxes excluded). Policies implemented thus far such as the Kyoto protocol, EU’s Emission Trading Scheme, and the Regional Greenhouse Gas Initiative in the US north-east, suggest that the preferred instrument is an emission quota per polluter. The prinicipal activity targ...

The Struggle over Migration Policy ∗ In this paper we analyze the endogenous determination of migration quota viewing it as an outcome of a two-stage political struggle between two interest groups: those in favor and those against the proposed migration quota. We first compare the proposed policies of the two interest groups under random behavior of the government, with and without lobbying. Th...
