The effect of coal combustion byproducts on price discrimination by upstream industries

Price discrimination is often difficult to disentangle from price dispersion due to a lack of transaction level data capable of tracking sales from individual companies to quantifiably heterogeneous groups of consumers. This paper uses mine-mouth prices and transportation prices paid by regulated coal-fired power plants in the U.S. coal market during the time period 2009–2010 to study how coal mines and transportation companies practice price discrimination against electricity plants. Power plants with heterogeneous demand for coal are perfectly identified based upon their ability to market flue-gas desulfurization (FGD) gypsum, which is a byproduct produced from scrubbing SO₂ emissions. Because sulfur is the raw material for FGD gypsum byproduct production, gypsum sellers are anticipated to have a more inelastic demand for high-sulfur coal. Results indicate that coal mines and transporters charge higher prices to gypsum sellers in comparison to non-sellers for transactions originating at the same mine during the same month of the same year. Coal-fired power plants capable of selling FGD gypsum byproducts are estimated to pay a 10.3–39.6 ¢/MMBtu price premium for coal. Coal mines and transportation companies each capture a relatively equal share of the associated rents.

Multivariate statistics in industrial marketing management: A practitioner tool kit

Much published work over the years has pointed to the differences between business-to-consumer (B2C) and business-to-business (B2B) marketing. An undesirable by-product of this sometimes misdirected distinction is that managers working within B2B environments have generally not considered the use of what are seen as B2C techniques, such as multivariate statistical analysis. This article is structured in three parts. First, the argument for the similarities between B2B and B2C marketing is developed; second, three different multivariate statistical techniques are presented and combined to form a practical tool kit for use by B2B managers on strategic, operational, and tactical levels; and third, the results of an application of the techniques in the life science research chemicals industry is reported, demonstrating that the tool kit substantially enhanced managerial understanding of customer decision processes.

Using patent information for designing new product and technology: keyword based technology roadmapping

With the rapid change in markets and technologies, it is becoming essential for firms to develop new products constantly. This can most successfully be achieved by using technology roadmaps (TRMs), which are effective tools for connecting product and technology planning. However, TRMs generally tend to overstate the qualitative and expert-dependent knowledge rather than incorporating quantitative and objective information. This paper proposes a new approach where patent data are used in a quantitative methodology to support reliable decision-making in roadmapping processes. In this study, text-mining techniques were utilized to extract the relevant information on which portfolio, co-word, and network analyses were carried out. The results were three types of product-technology maps that can be applied to specific roadmapping steps. The suggested approach is expected to yield useful information about roadmapping, and help improve the overall effectiveness and quality of the technique.
