Markus Feurstein, Martin Natter, Fast high precision decision rules for valuing manufacturing flexibility, European Journal of Operational Research, Vol. 120 (1), 2000. (Journal Article)
The valuation of Flexible Manufacturing Systems is one of the most frequently undertaken productivity improvement activities. In practice, the introduction of an FMS into industry must be done on the basis of cost justification. Recently developed techniques for the evaluation of the value of flexibility typically include the computation of stochastic dynamic programs. However, the computational effort of stochastic dynamic programs grows combinatorially and limits application to real world problems. In this contribution, we derive fast approximations to the stochastic dynamic program and compare their results to the exact solution. The proposed methods show an excellent worst case behavior (1%) for a wide range of volatility of the underlying stochastic profit margins and costs for switching the production mode. The computational effort is reduced by a factor of more than 200. |

Thomas Reutterer, Martin Natter, Segmentation Based Competitive Analysis with MULTICLUS and Topology Representing Networks, Computers & Operations Research, Vol. 27 (11-12), 2000. (Journal Article)
Two neural network approaches, Kohonen's Self-Organizing (Feature) Map (SOM) and the Topology Representing Network (TRN) of Martinetz and Schulten are employed in the context of competitive market structuring and segmentation analysis. In an empirical study using brands preferences derived from household panel data, we compare the SOM and TRN approach to MULTICLUS, a parametric approach which also simultaneously solves the market structuring and segmentation problem. Our empirical analysis shows several benefits and shortcomings of the three methodologies under investigation, MULTICLUS, SOM, and TRN. As compared to MULTICLUS, we find that the non-parametric neural network approaches show a higher robustness against any kind of data preprocessing and a higher stability of partitioning results. As compared to SOM, we find advantages of TRN which uses a more flexible concept of adjacency structure. In TRN, no rigid grid of units must be specified. A further advantage of TRN lies in the possibility to exploit the information of the neighborhood graph which supports ex-post decisions about the segment configuration at both the micro and the macro level. However, SOM and TRN also have some drawbacks as compared to MULTICLUS. The network approaches are, for instance, not accessible to inferential statistics. Our empirical study indicates that especially TRN may represent a useful expansion of the marketing analysts tool box. |

Steven Ongena, David C Smith, What determines the number of bank relationships? Cross-country evidence, Journal of Financial Intermediation, Vol. 9 (1), 2000. (Journal Article)
We investigate the determinants of multiple-bank relationships using a new data set comprising 1079 firms across 20 European countries. We document large cross-country variation in the average number of bank relationships per firm, uncovering a richness in European financial systems that extends beyond the standard description of being "bank-dominated". After controlling for a variety of firm-specific characteristics, we find that firms maintain more bank relationships, on average, in countries with inefficient judicial systems and poor enforcement of creditor rights. Firms also maintain more relationships in countries with unconcentrated but stable banking systems and active public bond markets. |

Robert Göx, Capacity planning under uncertainty in a Gutenberg production model, In: Theory of the firm: Erich Gutenberg's foundations and further developments, Springer, Berlin, p. 319 - 335, 2000. (Book Chapter)
The paper considers a two stage capacity and production planning model under uncertainty. The optimal second stage production policy falls into three cases: When capacity is slack the firm will produce with the cost minimizing production rate and adjust the production time to meet its output target. When the capacity constraint is binding, the firm will first adjust the production rate and then again produce with a constant production rate but employ overtime to meet the output target.
The optimal capacity choice of the first stage is determined by the trade off between the sunk costs of slack labor and the expected opportunity costs of adjusting the production rate and employing overtime in the case of a binding capacity constraint.
The key item determining the firm’s labor demand is the overtime premium. The amount of contracted labor strictly increases with the overtime premium and the expected overtime strictly decreases. Since then latter effect dominates the former for small overtime premia, the firm’s labor demand is first decreasing and then increasing with the overtime premium.
A reduction of overtime premia can be Pareto improving because it does not only lead to substantial cost savings but also an increasing labor demand. |

Robert Göx, Strategic transfer pricing, absorption costing, and observability, Management Accounting Research, Vol. 11 (3), 2000. (Journal Article)
This paper analyses the use of transfer pricing as a strategic device in divisionalized firms facing duopolistic price competition. When transfer prices are observable, both firms’ headquarters will charge a transfer price above the marginal cost of the intermediate product to induce their marketing managers to behave as softer competitors in the final product market. When transfer prices are not observable, strategic transfer pricing is not an equilibrium and the optimal transfer price equals the marginal cost of the intermediate product. As a strategic alternative, however, the firms can signal the use of transfer prices above marginal cost to their competitors by a publicly observable commitment to an absorption costing system. The paper identifies conditions under which the choice of absorption costing is a dominant strategy equilibrium. |
