Interactions with sea turtles have occurred at an alarming rate in swordfish longlining in Hawaii in recent years and various regulations have been put forward to protect sea turtles. In order to understand the cost of reducing sea turtle interactions, methods have been developed to derive the shadow price of sea turtle bycatch based on fisher's welfare loss from a specific regulation. This pap...

Education development is a critical component for a modern economy as the illiteracy rate can hinder economic growth. The illiteracy rate in China has decreased rapidly since 1980s, but there still exists an imbalance in distribution of educational resources among different regions. In order to explore the impacts of education quality on regional economic growth, we employ a quadratic direction...

The evaluation of the cost of reduction for the different region and the resulting emission permit prices is a typical model application. The usual approach to analyze emission trading is to obtain marginal emission reduction cost curves from the models and subsequently carry out a static, expost analysis of emission trading based on these cost curves. The drawback of this approach is that effe...

production of meat and milk is important activities in agriculture of fars province. nitrogen and phosphorus excretion by cows can result in pollution of the environment and increased cost of production. shadow prices of two environmental outputs of 60 beef cattle farms in shiraz which were selected by random sampling method, are assessed using two-stage procedure; linear programming and stocha...

In this paper we seek to enhance decision making of investments under multiple uncertainties. We assess optimal commitment strategies for future reference of pulp and paper mills given stochastically correlated processes of one input and two output prices. The price processes are consistent with shadow price trajectories of a large scale global energy model. For the detailed engineering model, ...
