Vertical integration and operational flexibility

Moretto, Michele; Rossini, Gianpaolo - 2008

The main aim of the paper is to highlight the relation between flexibility and vertical integration. To this purpose, we go through the selection of the optimal degree of vertical disintegration of a flexible firm which operates in a dynamic uncertain environment. The enterprise we model enjoys...

Investment Valuation with Tax-optimized Financing Decisions and a Tax-optimized Default Alternative

Hundsdoerfer, Jochen; Kruschwitz, Lutz; Lorenz, Daniela - In: BuR - Business Research 1 (2008) 1, pp. 9-24

In this paper we evaluate an indivisible investment project that is carried out in a corporation under very simple premises. In particular, we discuss a one-period model with certainty, the pure domestic case and proportional tax rates. Surprisingly, the decision problem turns out to be rather...

The Risk Management of Minimum Return Guarantees

Mahayni, Antje; Schlögl, Erik - In: BuR - Business Research 1 (2008) 1, pp. 55-76

Contracts paying a guaranteed minimum rate of return and a fraction of a positive excess rate, which is specified relative to a benchmark portfolio, are closely related to unit-linked life-insurance products and can be considered as alternatives to direct investment in the underlying benchmark....

Integrating Pricing and Inventory Control: Is it Worth the Effort?

Gimpl-Heersink, Lisa; Rudloff, Christian; Fleischmann, … - In: BuR - Business Research 1 (2008) 1, pp. 106-123

In this paper we first show that the gains achievable by integrating pricing and inventory control are usually small for classical demand functions. We then introduce reference price models and demonstrate that for this class of demand functions the benefits of integration with inventory control...

Coordinated Lot-sizing and Dynamic Pricing under a Supplier All-units Quantity Discount

Transchel, Sandra; Minner, Stefan - In: BuR - Business Research 1 (2008) 1, pp. 125-141

We consider an economic order quantity model where the supplier offers an all-units quantity discount and a price sensitive customer demand. We compare a decentralized decision framework where selling price and replenishment policy are determined independently to simultaneous decision making....
