基于提前期和价格折扣的延迟交货和库存策略研究

研究了基于提前期和价格折扣的延迟交货和库存策略,其中的价格折扣是基于提前期的价格折扣,即当出现缺货而不能在既定的提前期内交货时,企业就会提供一个价格折扣,这时会有一部分顾客愿意等待,直到订单被满足,即延迟交货。其中,愿意等待延迟交货的比例跟提前期成反比关系,提前期的各部分都可以通过增加成本来实现压缩。     

Can intertemporal choice experiments elicit time preferences for consumption?

The paper considers what can be inferred about experimental subjects’ time preferences for consumption from responses to laboratory tasks involving tradeoffs between sums of money at different dates, if subjects can reschedule consumption spending relative to income in external capital markets. It distinguishes three approaches identifiable in the literature: the straightforward view; the separation view; and the censored data view. It shows that none of these is fully satisfactory and discusses the resulting implications for intertemporal decision-making experiments. JEL Classification C90, C91, D90, D91, D11, D12     

Persistence of Shocks to Output in Austria and Theories of Economic Growth

The paper analyzes the degree of output persistence in GDP in order toempirically discriminate between the Solow growth model, the perfect competition endogenous growth model and the imperfect competition endogenous growth model for the case of Austria. Wefind that a shock in the growth rate of output induces a permanent and larger effect on the level of GDP. This leads us to refute the Solow growth model and the perfect competition model of endogenous growth.We may not reject the imperfect competition growth model.     

Time variation in the cointegrating relationship between stock prices and economic activity

The present paper examines whether there exists a long‐run cointegrating relationship between a stock market index and output and interest rates. Moreover, estimation is conducted over the full sample and both a recursive and rolling sample to examine any time variation in the nature of the relationship. The results support evidence of a single cointegrating vector, where stock prices typically exhibit a positive relationship with industrial production and a negative relationship with interest rates. However, there is significant time variation and periods of time where contrary results are observed. As such any model of stock prices needs to account for such time variation     

中国经济体制改革时期制度变迁的特征分析

从实质上说，中国经济体制改革的过程就是一个制度的重建过程，即以适应市场经济的制度安排取代适应计划经济的制度安排取代适应计划经济的制度安排的过程。在这一制度重建的进程中，市场取向的制度变迁表现出八个方面的典型特征：一是制度变迁需求的内性性；二是制度变迁供给的滞后性；三是制度变迁目标的动态性；四是制度变迁过程的渐进性；五是制度变迁轨迹的路径依赖性；六是从单项制度变迁向制度结构变迁演进；七是强制性制度变迁与诱致性制度变迁相结合；八是宏观经济制度变迁与微观经济制度变迁同步进行。     

生产劳动力的劳动时间的探讨

传统经济学的劳动力价值理论只有生产劳动力的生产费用(物化劳动),没有生产劳动力的劳动时间(活劳动)的耗费。劳动力的生产也有劳动时间的耗费。劳动力的自然再生产时间不形成劳动力的价值,劳动力的社会再生产时间、即学习劳动的时间形成劳动力的价值。劳动力价值包括两个部分:一是生产劳动力的物化劳动,如生活费用和学习费用等;二是生产劳动力的活劳动即学习劳动。
