Budget deficits and real interest rates: Updated empirical evidence on causality

Using error-correction model (ECM) estimation, the paper empirically examines the causality relationship between the federal government budget deficit and the ex ante real interest rate yield on high grade long term tax free municipal bonds in the U.S. To clarify this deficit or interest rate relationship, the budget deficit is measured by the primary budget deficit, which excludes net interest payments by the Treasury. In a model that includes federal personal income tax rates and net international capital flows, as well as money supply growth, the ECM estimates strongly suggest a bi-directional relationship between the primary budget deficit and the ex ante real interest rate yield. Budget deficits apparently do matter! William Simon's concerns were justified.The author is indebted to P. A. V. B. Swamy for ideas and helpful suggestions and Will Perry for data assembly and processing.     

论卓炯经济理论的生命力

本文认为，卓炯虽然离开我们十多年，但是，卓炯经济思想仍然具有强大的生命力。卓炯在马克思主义经济理论研究上取得的成就，仍然处于理论前沿。卓炯的分工理论，不但是古今经济学家着迷的课题，还是20世纪80年代兴起的新兴古典经济学的理论基础。卓炯关于市场机制配置资源优化的市场经济理论，不但是古典、新古典经济学的理论核心，还是经济学永远绕不开的中心论题。卓炯提出的市场经济模式经受了改革开放实践的考验，继续放出夺目的理论光彩。继承和发展卓炯经济理论是广东经济学家的光荣和骄傲．是义不容辞的理论任务。

MANAGING VENDOR INVENTORY IN A DUAL LEVEL DISTRIBUTION SYSTEM

Collaborative arrangements among members of the supply chain have received a great deal of interest in recent years as a means of reducing costs. One such arrangement is vendor managed inventory (VMI). VMI allows the vendor to make decisions concerning the quantity and timing of deliveries to the retailer. Such an arrangement offers the potential of a more efficient supply chain by removing the negative effects of retail ordering policies. A thorough review of the literature was conducted to identify factors likely to impact the performance of a VMI partnership. Computer simulation was used to study the effects of these factors from both the vendor's and retailer's perspectives. The results lend insight into the performance of VMI and guidance for managers as to the environments in which VMI is most effective.
