EOQ application in a pharmaceutical environment: A case study

This paper describes a successful application of classical inventory theory at a drug manufacturing plant located in Montreal that has resulted in annual savings in the order of $110,800 and assisted management in its decision to invest in larger production equipment. The basic assumptions underlying EOQ models are reviewed and dealt with. For instance, an algorithm was devised to handle the peaks in the demand of many A class items. Following the implementation of this algorithm, buffer stocks were reduced signifi cantly while maintaining the same high levels of service.     

Much ado about mentors

An international management firm conducted a study of executives that included questions regarding compensations, personal data, and current position. It was of special interest to determine the effect of mentor and protege relationships on business careers. Of the individuals surveyed, two-thirds reported a relationship with a senior person who took a special interest in their career, during the first five years of their professional development. In general, executives who had a mentor are better educated, earn more money at an earlier age, more apt to follow a career plan and report high job satisfaction. The majority of sponsors are older businessmen holding positions of authority and who feel that personnel development and management succession are key responsibilities. The following characteristics of a mentor are judged most important: willingness to share experiences, knowledge of the organization, organizational power and respect from peers. Mentor-protege relationships frequently develop into lengthy friendships which in turn encourage young executives to eventually sponsor their own proteges.     

Frame of reference rater training issues: recall,time and behavior observation training

This study investigated three controversial issues regarding frame of reference training (FOR), a type of rater training: (1) Does it improve behavioral recall, (2) Can it be improved by incorporating behavior observation training (BOT), and (3) Can its effects persist over time? Results suggested that even though FOR training increases the number of behaviors recalled, it does not necessarily improve the quality of the recalled behaviors, but a combined FOR + BOT program does improve recall quality. Lastly, results suggested that FOR training can improve rating accuracy, even after a two‐week delay between rater training and the rating task.     

Histogram-based prediction of directional price relatives

A model of directional prediction of price relatives is proposed following the histogram-based scheme developed in Györfi et al. (2006). This methodology allows us to exploit potential information contained in multivariate series of price relatives. The impact of the model is studied from the perspective of an economic agent through the use of double linear loss functions. A numerical example with real data is presented to illustrate the model.     

Liquidity risk,price impacts and the replication problem

We extend a linear version of the liquidity risk model of Çetin et al. (Finance Stoch. 8:311–341, 2004) to allow for price impacts. We show that the impact of a market order on prices depends on the size of the transaction and the level of liquidity. We obtain a simple characterization of self-financing trading strategies and a sufficient condition for no arbitrage. We consider a stochastic volatility model in which the volatility is partly correlated with the liquidity process and show that, with the use of variance swaps, contingent claims whose payoffs depend on the value of the asset can be approximately replicated in this setting. The replicating costs of such payoffs are obtained from the solutions of BSDEs with quadratic growth, and analytical properties of these solutions are investigated.     

The purchase versus illegal download of music by consumers: the influence of consumer response towards the artist and music

Based on qualitative and quantitative surveys, I show that consumer responses toward a particular song and toward its performer(s) play distinct roles in explaining consumer choices to either buy or illegally download that song. The various types of consumer responses to songs and artists are first identified through qualitative research and then validated through exploratory and confirmatory factor analyses (CFA) of survey data. While consumer responses to music explain the need to reexperience and acquire the song, consumer responses to performers explain purchase over illegal downloading. Copyright © 2007 ASAC.
