A New Method for Heteroscedasticity of Term Structure Model Using Exponential Splines

Abstract: Exponential splines are introduced based on the definition of the spline bases. Exponential splines model of this paper and that of Martellini and Priaulet are proved to be the same in theory. Based on the Chinese treasury market's characteristic and oversea methods for estimating term structure of interest rates, heteroscedasticity of term structure model of interest rates is discussed and a new method for dealing with heteroscedasticity of term structure model, namely confirming a certain bond's size of variance according to its trading volume of the market is offered. Empirical research and comparison of this model with others are carried out using the data of Chinese treasury market. The results show that the method can significantly decrease the errors of government bond pricing. The new method is better than the foreign traditional method for dealing with heteroscedasticity of term structure model and is more suitable to our national fact.

Empirical Tests for Term Structure of Interest Rates Based on Nonlinear Adjustment

Abstract: The traditional method of unit root test has been discussed and the method of unit root test under non-linear adjustment, exponential smooth transition autoregressive, has been introduced. Based on Chinese interbank repo rates, empirical tests are made: Nonlinearities of interest rates and their spreads have been tested, and unit root tests are paid to the level, the first difference and the spread of interest rates based on the traditional method and the exponential smooth transition autoregressive method respectively. The results show: There are remarkable non-linear adjustment characteristics in the Chinese interbank repo rates spread. After considering non-linear adjustment, daily rates and monthly rates are co integrated with the vector (-l,l)',and the long-run equilibrium relationship between them is stable. The results provide strong evidence against the unit root of the yield spread between daily interest rates and monthly interest rates. The findings show that the term structure of interest rates is stable with nonlinear adjustment.

Returns Management Information System: A Case of Paint Manufacturers

Abstract: Reverse logistics activities in paint manufacturer mainly are products returns. Manufacturers can redistribute these returns directly at a discount or reuse their materials and packaging. Paint manufacturer is inclined to reduce returns which always bring negative effect. Good forward supply chain management can decrease return in some extent. These measures including: products returns' measuring, relative restricted returns policies, formalization of reverse logistics programs and closed supply chain management information system etc. For better control and management of these return activities, business process reengineering based on information system which integrated into forward supply chain is proposed in the paint manufacturers. A case of the paint manufacturers is analyzed here as an example to show the fore-and-aft business process change.

A Polynomial Time Algorithm for Coordination of Pricing and Lot Sizing Model with Backlogging

Abstract: In decentralized policy, lot sizing models with backlogging (LSP-B) tend to neglect the effects of market on production. In this paper, pricing is introduced into general LSP-B and by coordinating pricing and LSP-B, the rational price can be set such that the firm's profit is maximized. Demand is a deterministic function of price. It is primarily concerned that the same selling price on a product is maintained throughout horizon. An exact algorithm is developed to solve joint fixed pricing and LSP-B in polynomial time. The algorithm is based on alternate decisions on pricing and production. By restarting the alternate decisions repeatedly, the optimal pricing and corresponding production plan can be solved recursively. Results show that the joint policy may contribute more profit to the firm than the decentralized policy.
