This paper contributes to the analysis of the money supply process in Germany during the period of monetary targeting by the Bundesbank from 1975-1998. While the standard money multiplier approach assumes that the money stock is determined by the money multiplier and the monetary base it is argued here that both the money stock and the monetary base are determined endogenously by the optimizing...

This paper examines an integrated decision-making process regarding pricing for uncertain demand and sourcing from uncertain supply, which are often studied separately in the literature. Our analysis of the integrated system suggests that the base stock list price policy fails to achieve optimality even under deterministic demand. Instead, the optimal policy is characterized by two critical val...

This article analyzes a model of a multiechelon inventory system. The exogenous demands form Markov-modulated Poisson processes. That is, the demand rates are functions of an underlying Markov chain. Each location follows a base-stock policy which is independent of the state of the underlying Markov chain. We employ the exogenous transit mechanism introduced by Zipkin [7) and Svoronos and Zipki...

This paper studies how the difference between technical depreciation and tax depreciation affects the firm’s optimal investment strategy. The objective is maximization of shareholder value. When tax depreciation differs from technical depreciation, an additional investment not only generates value due to the fact that the firm can produce more, but also due to the fact that an additional deferr...

The ”irrational exuberance” of the stock market in the late 1990’s lead to a discussion of the appropriate policy response by monetary authorities. Any response would be contingent on the stock market reaction to policy shocks. In this study I employ a structural VAR to estimate the response of the stock market returns to innovations in the federal funds rate. The effect of the stock market on ...

We consider an assembly system with multiple stages, multiple items, and multiple customer classes. The system consists of m production facilities, each producing a different item. Items are produced in variable batch sizes, one batch at a time, with exponentially distributed batch production times. Demand from each class takes place continuously over time according to a compound Poisson proces...

In this paper, we develop an economic production quantity (EPQ) model under machine breakdown and two types of repair (corrective and preventive). also, study the simultaneous effect of holding safety stock and purchasing policy. In order to avoid shortages occurring as a result of the random repair time, in addition to keep safety stock, we suppose that the manufacturer could purchase some qua...

Billions of dollars worth of shares are traded in the stock market on a daily basis. Many people depend on the stock market as their primary source of income while others have their retirement funds tied to the stock market. The importance of “good” performance of the stock market is obvious. History has shown that a downturn in stock prices can cause major disturbances in the lives of many. Al...

OBJECTIVE To review original research studies published between 1990 and 2004 on the access and use of medicines in Mexico to assess the knowledge base for reforming Mexico's pharmaceutical policy. MATERIAL AND METHODS A literature review using electronic databases was conducted of original studies published in the last 15 years about access and use of medicines in Mexico. In addition, a manu...
