We examine the different effects of monetary policy actions and central bank communication on China's stock market bubbles with a Time-varying Parameter SVAR model. We find that with negative responses of fundamental component and positive responses of bubble component of asset prices, contractionary monetary policy induces the observed stock prices to rise during periods of large bubbles. By c...

We consider a capacitated supply system that produces a single item that is demanded by several classes of customers. Each customer class may have a different backorder cost, so stock allocation arises as a key decision problem. We model the supply system as a multicustomer make-to-stock queue. Using dynamic programming, we show that the optimal allocation policy has a simple and intuitive stru...

dividend policy is one of the most important financial decisions that managers encounter. this study contributes to the literature of dividend and empirical research investigating the effects of dynamic factors in tehran stock exchange. based on some criteria, the study contains 133 listed firms over a 10-year period from 2001 to 2010. to test the research hypotheses, this study uses fixed effe...

The analysis of monetary policy impact via interest rate as instrument of intervention on the evolution of stock market prices has gained more popularity during the current crisis due to the accumulation of financial imbalances. This article investigates the impact of monetary policy on equity indexes in European Union countries from January 2000 to February 2012, using cointegration and Grange...

In this paper, we analyze a repair shop serving several fleets of machines that fail from time to time. To reduce downtime costs, a continuous-review spare machine inventory is kept for each fleet. A spare machine, if available on stock, is installed instantaneously in place of a broken machine. When a repaired machine is returned from the repair shop, it is placed in inventory for future use i...

Introduction The periodic-review inventory control problem with lost-sales and positive lead times is one of the most fundamental yet notoriously difficult problems in the theory of inventory management (see Zipkin (2000)). The model assumes that unmet demand at the end of each period is lost, rather than being backlogged and carried over to the next period. For example, in many retail applicat...

An enterprise network is analyzed from the viewpoint of an end-product manufacturer who receives customer orders and organises his production and supply policy so as to minimize the sum of his average holding cost and average stock-out cost. For each main component to be ordered, the producer has several possible suppliers. The arrivals of customers’ orders are random and delivery times from su...

In this paper, we consider inventory models for periodic-review systems with replenishment cycles, which consist of a number of periods. By replenishment cycles, we mean that an order is always placed at the beginning of a cycle. We use dynamic programming to formulate both the backorder and lost-sales models, and propose to charge the holding and shortage costs based on the ending inventory of...
