We provide a simple model to investigate decisions about vertical separation. The key feature of this model is that more than one input is required for the final product of the downstream monopolist. We show that as the bargaining powers of independent complementary input suppliers grow larger,...

We provide a theoretical framework to discuss the relation between market size and vertical structure in the railway industry. The framework is based on a simple downstream monopoly model with two input suppliers, labor forces and the rail infrastructure firm. The operation of the downstream...

We provide a simple model to investigate decisions on vertical integration/separation. The key feature of this model is that more than one input is required for the final products of the local downstream monopolists. Depending on their cost structure, downstream firms' decisions on vertical...

We consider a bilateral monopoly with a supplier and a buyer. Their trading terms are determined through negotiations, but affected by the buyer's efforts to search for outside suppliers. We find surprisingly that a market expansion may harm the supplier.

This paper is an annual publication issued by the Microeconomic Analysis service of the National Bank of Belgium. The Flemish maritime ports - Antwerp, Ghent, Ostend, Zeebrugge - and the Autonomous Port of Liège play a major role in their respective regional economies and in the Belgian...

This paper provides a survey of the main developments in the iron and steel industry over the last few decades. The first chapter covers the changing conditions on international markets and identifies the main challenges facing the companies in this sector. These include the boom in China, the...

We analyze firms' decisions to adopt a vertical integrated or decentralized structure taking into account the characteristics of both the final good competition and the R&D process. We consider two vertical chains, where R&D is conducted by upstream sectors. R&D investment determines the...

We investigate a model in which a monopoly supplier distributes two types of its product through a traditional retailer with a wholesale price contract and an online retailer with an agency contract. Because such an agency contract eliminates the double marginalization problem, the online...
