Labour as a Buffer: Do Temporary Workers Suffer? In this paper, we investigate whether or not there is an equal opportunities dimension to regulating equal pay and conditions for temporary work. We develop a “buffer stock” model of temporary work that suggests a number of reasons why ethnic minorities and women may be more likely to be on fixed-term contracts than comparable white males. Using ...

In this paper we investigate whether or not there is an equal opportunities dimension to regulating equal pay and conditions for temporary work. We develop a “buffer stock” model of temporary work that suggests a number of reasons why ethnic minorities and women may be more likely to be on fixed-term contracts than comparable white males. Using three different British datasets (a random represe...

This paper tests a straightforward implication of the basic Life Cycle model of consumption: that current consumption depends on expected lifetime income. The paper projects future income for a panel of households and finds that consumption is closely related to current income, but unrelated to predictable changes in income. However, future income uncertainty has an important effect: consumers ...

Inventory systems with uncertainty go hand in hand with the determination of a safety stock level. The decision on the safety stock level is based on a performance measure, for example the expected shortage per replenishment period or the probability of a stock-out per replenishment period. The performance measure assumes complete knowledge of the probability distribution during lead time, whic...

Most logistics managers face uncertainty in demand which forces them to hold safety stock to provide high levels of service to their customers. The level of safety stock depends on what the company’s targets are on some performance characteristics of an inventory management decision problem like the expected number of units short or the stock-out probability. In the case only incomplete informa...

This paper discusses the issue of order crossover and its effects in order point, lot size (s, Q) inventory systems. Orders are likely to cross when their lead times are stochastic. Two inventory systems are considered to examine the consequences of order crossover. The first inventory system considers a fast moving item having deterministic demand and stochastic lead time. It is assumed lead t...

Because the budget constraint implies that consumption must eventually fully adjust to permanent shocks, intuition suggests that consumption-smoothers will have an immediate marginal propensity to consume of one out of permanent shocks. However, this paper shows that if consumers are impatient and experience both transitory and permanent income shocks, the immediate marginal propensity to consu...

The budget constraint requires that, eventually, consumption must adjust fully to any permanent shock to income. Intuition suggests that, knowing this, optimizing agents will fully adjust their spending immediately upon experiencing a permanent shock. However, this paper shows that if consumers are impatient and are subject to transitory as well as permanent shocks, the optimal marginal propens...

This paper seeks the critical factors for a correct choice in the components set up along the supply chain. ABC classification was made for all the suppliers according to the supplied items for the company. After a demand analysis, the seasonal nature and trend during the timeline, we used the last four years registers where is shown a decreasing behavior in 30% of the items; Economic Order Qua...
