Indirect Damages from Price Fixing: The Alabama Lysine Case

Indirect damages to broiler and pork producers fromsupra-competitive pricing of synthetic lysine, whichis an important feed additive, are discussed in thisarticle. Indirect damages occur in fundamentallydifferent ways in the two industries because thebroiler industry is vertically integrated while thepork industry was dominated by independent producersduring the 1992–1995 time period. Pass-through ofhigher lysine prices to hog feed purchasers isdemonstrated with regression analysis of purchasesof a feed premix containing synthetic lysine and aregression analysis of purchases of synthetic lysinefrom feed dealers.     

Endogenous horizontal mergers under cost uncertainty

This paper presents a study of endogenous horizontal mergers under cost uncertainty. Before knowing the exact values of their costs, firms decide sequentially whether or not to join a merger. After the merger decision is made, uncertainty is resolved and firms engage in Cournot competition with incomplete information about one another's costs. Due to production rationalization, the merged firms enjoy an advantage over non-merged firms in the sense that the merged firms' expected cost is lower. I show that mergers occur if and only if the uncertainty is large and that the larger the uncertainty, the greater the number of firms that will merge. Although a merger reduces competition and therefore hurts consumers, it improves productivity under cost uncertainty. I find that a merger increases social welfare whenever there are at least four firms in the industry before the merger.     

Detailed cost estimating in the automotive industry: Data and information requirements

The automotive industry operates in a very competitive market which requires controlling product costs, improving the product quality and shortening the development lead time. Cost estimation requires quality data and information, therefore this research project identified several issues that hinder this activity, namely a lack of resources and information acquiring and validation difficulties. This research paper presents the various data and information requirements for detailed cost estimating in automotive industry. The research project has identified the common cost estimation process model within the identified industry sector. The study identified the types of data and information requirements for cost estimating. It has also constructed the relevant data infrastructure as the basis for a Web Portal, which is the physical presentation of the information infrastructure. Multiple sources of data collection techniques were employed to identify the types of data needed for detailed cost estimates within a manufacturing company. These techniques include participant observation, semi-structured interviews, process models and document analysis of six different UK based automotive companies. Methods of process modelling like IDEF3 and knowledge capture technique known as X-Pat (eXpert Process Knowledge Analysis Tool) were employed in this study.This study makes several contributions concerning both conceptual and practicable information issues that have long vexed detailed cost estimating practices in the automotive industry. The study conceptually defines the detailed bottom-up information (i.e., individual cost elements and the links between them) needed for an accurate estimate of cost, and shows why each element of information is needed and where it fits into the cost model. To respond to the practicable information vexations, the study shows where to find the necessary cost information and proposes a validation method. The research creates useful knowledge in the form of an improved understanding of information requirements for cost estimates. The benefits to the industry of better cost estimates based on this research at the conceptual design stage include improved cost control and enhanced ability to adjust to anticipated market trends.

Using least squares support vector machines for the airframe structures manufacturing cost estimation

Accurate cost estimation plays a significant role in industrial product development and production. This research applied least squares support vector machines (LS-SVM) method solving the problem of estimating the manufacturing cost for airframe structural projects. This research evaluated the estimation performance using back-propagation neural networks and statistical regression analysis. In case studies, this research considered structural weight and manufacturing complexity as the main factors in determining the manufacturing labor hour. The test results verified that the LS-SVM model can provide accurate estimation performance and outperform other methods. This research provides a feasible solution for airframe manufacture industry.

The cost allocation issue in joint replenishment

Joint replenishment for several products to achieve a lower inventory logistics cost has been a topic of extensive studies. Less attention has been paid to the issue of deciding how the joint replenishment costs should be allocated across the individual products. Ideally, when items are ordered together one would require a stable cost allocation, such that no subset of products subsidizes another subset. When part of each product's ordering cost is product specific and part can be shared with other products (like in a 3PL setting of Anily and Haviv), it has been shown that even when a stable allocation exists, such an allocation might be difficult to compute. In addition, usually the components of ordering costs are partially determined using estimates and accounting discretion. This paper provides two main insights for determining an appropriate cost allocation. It provides the means to test how sensitive a stable cost allocation is to a range of cost parameter values. Then, in a computational study, it is shown how to obtain a stable cost allocation without excessive computation.

Product price and performance level in one market or two separated markets under various cost structures and functions

Market characteristics, including intrinsic demand and customer sensitivity on price and product performance level, are distinct at different markets. Comparisons of various product development strategies in one market or two geographically separated markets are conducted for three classes of products: development intensive products (DIPs) with constant unit cost, marginal cost-intensive products (MIPs) with constant fixed cost, and marginal and development intensive products (MDIPs) with non-constant unit cost and fixed cost. Results show that larger demand size, less customer sensitivity on price and/or more sensitivity on performance level lead to more profit, a higher sale price and a not-lower product performance. The customer reservation or the saturation performance level should be generally adopted though the optimal performance level does exist occasionally. Unit cost and/or fixed cost must increase in performance at an increasing rate for the existence of one optimal performance level. Due to the impact of demand size, one high-end (low-end) MDIP or DIP could be introduced into one low-end (high-end) market at a different price if the demand size is significantly large in the low-end market. For DIPs, offering one niche high-end product is not worse than offering the low-end product into two markets. For MIPs with negligible fixed cost, the product line strategy is not worse than the standard product development strategy. Additionally, the product cost reduction approach adopted in one product line has significant effects on the best product development strategy and sequence.

On the determinants of non-market strategy: The separations mechanism and cost shifting in the telecommunications industry

This study examines the relationship between performance levels and the levels of cross-subsidy attained by local exchange carriers in the United States telecommunications industry. These cross-subsidies have been obtained by firms via their engagement in a separations mechanism, based on a cost allocation process, which telecommunications sector regulatory authorities use. Non-market strategies have assumed primacy in the activities of several sectors world-wide. Thus, understanding non-market strategic choices is important in the analysis of firms’ behavior and performance. Active engagement in the separations process is an important non-market strategy in the telecommunications industry, as a firm relatively successful in this activity can gain large cross-subsidies. The analysis establishes that less profitable firms obtain greater cross-subsidies. Once the profitability variable is decomposed into its two main components, which are productivity and price recovery, the impact of the profitability variable reduces. Firms which are relatively unproductive, as well as those unable to recover higher output prices, obtain relatively greater cross-subsidies. These results are inconsistent with the postulates of the strategic cost-allocation and behavior literatures but are consistent with x-inefficiency and rent-seeking perspectives of firms’ strategic actions.     

The impact of different fibre access network technologies on cost,competition and welfare

Using a novel approach to the evaluation of new network technologies that combines an engineering cost model with a differentiated multi-player oligopoly model with wholesale access regulation this article evaluates the choice among different Fibre-to-the-Home (FTTH) architectures. The cost modelling relies upon an engineering bottom-up approach that feeds into a competition model. For addressing competition the pyramid model was chosen, which is an extension of the Hotelling model to multiple firms/services. The paper solves for price setting Nash equilibria between an incumbent, wholesale-access-based entrants and cable as an additional fully integrated network competitor. Welfare tradeoffs are highlighted with respect to cost differences and QoS differences between the various FTTH architectures and between the modes of regulation. According to the analysis architectures that can be unbundled (and that allow for greater speeds) outperform, from a social welfare perspective, architectures that (realistically) allow only for bitstream access.

The consequences of voluntary traceability system for supply chain relationships. An application of transaction cost economics

This paper analyses the effects of voluntary traceability on vertical relationships within food supply chains using a transaction cost perspective. The analysis makes reference to the Italian situation where the national standard organization has introduced a private standard for traceability that provides a higher degree of information associated with the individual product than the European mandatory traceability system. A survey was conducted by questionnaire to assess changes in transaction characteristics, costs and governance after the introduction of voluntary traceability. The sample represents all Italian firms applying this standard. Factorial and cluster analyses were applied to find the different reorganizations of transactions. The results highlight an increase in asset specificity and a decrease in the uncertainty level throughout the supply chains. The introduction of voluntary traceability shows increased vertical coordination for firms that previously used oral agreements and variation in transactions conditions for firms using contracts. Instead vertically integrated firms do not reveal any variation in the governance of transactions as they are already internally safeguarded.     

Procurement cost reduction for customized non-critical items in an automotive supply chain: An action research project

This paper presents the processes involved in organizing a buyers' fair, a fair where first- and second-tier suppliers of the automotive industry make known their buying requirements for non-critical items to SMEs (small and medium-sized enterprises). The fair allowed the procurement process of LCs (large companies) and the prospecting process of SMEs to be faster and less-expensive. The fair was the result of an action research project performed by the researchers in partnership with the Brazilian Federation of Industries.     

On commodity taxation in vertically differentiated markets

We examine the impact of commodity taxation on vertically differentiated product markets when entry is allowed. We show that an ad valorem tax may have a dramatic effect on market structure by inducing the entry of a large number of firms in what was previously a natural monopoly. The producers of high quality products reduce market share after an increase in their unit production cost, leaving more room for lower quality products. While within a given market structure aggregate quality decreases monotonically with the tax rate, quality jumps upwards at tax rates that cause a change in market structure.     

Airport deregulation: Effects on pricing and capacity

We use a model of vertical relations between two congestible airports and an airline oligopoly to examine, both analytically and numerically, how deregulation may affect airports prices and capacities. We find that: (i) unregulated profit-maximizing airports would overcharge for the congestion externality and, compared to the first-best, would induce large allocative inefficiencies and dead-weight losses. They would restrict capacity investments but, overall, would induce fewer delays; (ii) Welfare maximization subject to cost recovery performs quite well, achieving congestion levels similar to a private-unregulated airport but without inducing such large traffic contraction; this puts a question mark on the desirability of deregulation of private airports; (iii) Increased cooperation between airlines and airports provides some improvements, but the resulting airport pricing strategy leads to a downstream airline cartel; (iv) When schedule delay costs effects are strong and airline differentiation is weak, it may be optimal to have a single airline dominating the airports, but this happens only when airports' pricing schemes render the number of airlines irrelevant for competition.     

Innovation and integration in the agri-food industry

We deal with the link between innovation and market structure using the empirical example of the Danish agri-food industry. Vertical integration may resolve hold-up problems and here we test for the importance of vertical integration and networks on innovation. We further examine the effects of network relationships on innovation behaviour. We use data from an extensive survey of 444 Danish firms over two years, 2000 and 2005 to estimate a bootstrapped zero-inflated Poisson regression model. The first and most significant result is that organization matters. Further we find that vertical integration as well as contractual arrangements are significant determinants for firms’ innovation behaviour. The direction of integration is important as well. Also, economies of size seem to play an important role. Similarly, the export orientation of the firm is a significant determinant of innovation whereas the sector the firm is operating in is not significant for its innovation behaviour.
