This study addresses the empirical viability of microstructure models of dealer price setting. New evidence is presented rejecting these models' specifications of how information asymmetry and inventory accumulation affect dealer pricing. This rejection is consistent with those of other...

Using an audit trail transaction data set compiled by the Commodity Futures Trading Commission (CFTC), we seek to ascertain directly the motives behind dual traders’ own account trading and whether or not they are informed traders. We estimate our system of equations on each of the 101 most...

The objective of the study is to determine the factors of the optimal level of merchandizing inventory. The study is based on a mathematical model. The results revealed some interesting findings. The most important conclusion is that the 'Usage of Material' or the Sales Volume is not the real...

In this article a single item inventory model with backlogging is analyzed, which is a generalization of the most well-known simple models. This formulation enables us to separate the analysis of the system to the analysis of the control rule (reduced to the analysis of a Markov chain) and of...

In equipment-intensive industries such as truck manufacturing, electronics manufacturing, photo copiers,and airliners, service parts are often slow moving items for which, in some cases, the transshipment timeis not negligible. However, this aspect is hardly considered in the existing spare...

Organizations with large-scale inventory systems typically have a large proportion of items for which demand is intermittent and low volume. We examine different approaches to forecasting for such products, paying particular attention to the need for inventory planning over a multi-period...

This article concerns the subject of demand forecasting and stocks status planning in online shops. One described the ways of materials management and setting the groups of most important products. The second part of the article contains the analysis of surveys results. They were conducted in...

The general aim of this article is to present genetic algorithms as a tool, that can be used in de-mand forecasting in internet shops. First part of article identities factors, which have to be taken into consideration during analysing demand in internet shops, e.g. dispersion of demand,...

This article presents a model of ABC analysis tailored for internet shops. The standard set of criteria is expanded to cover e-commerce specific characteristics, such as the number of product views, search engine rankings and product links via a recommendation system..The proposed new...

While the net present value (NPV) approach is widely accepted as the right framework for studying production and inventory control systems, average cost (AC) models are more widely used. For the well known EOQ model it can be veri_ed that (under certain conditions) the AC approach gives near...
