The objective of this research is to estimate the economic impact of climate change on tea production in China. We use historical weather and production data from 1980 to 2011 to construct a yield response model from panel data that estimates the partial effect of specific weather factors on tea...

This note deals with the optimality conditions of set-valued unconstraint optimization problem in real normed linear spaces. Based upon the concept of contingent epiderivative, the unified necessary and sufficient optimality conditions for global proper efficiency in vector optimization problem...
