Bullwhip Effect and Assess of the Information Sharing Under ARIMA(0,1,1)Demand ZHANG Qin, DA Qin-li, SHEN Hou-cai 2001, (6):  1-6.  Abstract ( 2529 )   PDF (1398KB) ( 2480 )   Save The paper considers a two echelon supply chain which contains a single supplier and one retailer.It studies bullwhip effect and values of the information sharing between the supplier and the retailer under ARIMA(0,1,1)demand,and compares the differences before and after information sharing.The results show that information sharing can bring the benefits such as mitigating bullwhip effect,decreasing on hand inventories and reducing the cost for the supplier.

Empirical Test on Convertible Bond Pricing Model under Stochastic Interest Rate FAN Xin-ting, FANG Zhao-ben 2001, (6):  7-14.  Abstract ( 2139 )   PDF (1131KB) ( 2255 )   Save This paper does empirical test on convertible bond pricing model under stochastic interest rate In the market without short position prohibition,as for the in the value convertible bonds,the model can get satisfactory pricing directly As for the out of the money convertible bonds,the model can’t get satisfactory pricing until it takes intent default risk into account and adds risk premium in In the market with short position prohibition,such as Chinese domestic financial market,the model can only provide some pricing information for the convertible bonds just in converting period.
