We find parents＇ needs for care significantly affect adult children＇s participation in migrant labor market. Joint family decisions have also been made among adult siblings as far as elderly support is concerned. Different patterns of migrant labor force participation in Zhejiang and Gansu provinces largely reflect the differences between their respective migrant labor markets. Understanding of these new patterns of China＇s internal migration helps policy makers in China and other developing counties formulate effective social policies, and consequently, a more appropriate urbanization path.展开更多

According to the marketing practices, which retailers sell their products in different periods with the different marketing policies, we depict the jointed decision question with a stochastic dynamic programming model from the view of the centralized system. Then, we prove that the expected profit function are concave on decision vectors respectively, and develop the decision method for ordering and pricing. Lastly, we design the iterative search arithmetic to find the optimal decision vectors.展开更多
