We examine the interplay of endogenous vertical integration and cost-reducing downstream investment in successive oligopoly. We start from a linear Cournot model to motivate our more general reduced-form framework. For this general framework, we establish the following main results: First,...

Die vorliegende Dissertation besteht aus vier Kapiteln. Das erste Kapitel zeigt unter Verwendung von Schweizer Firmendaten, dass eine Senkung von Handelsbarrieren zwischen der Schweiz und der Europäischen Union zu Unternehmen führt, die einen geringeren Grad an vertikaler Integration...

This paper examines the competitive effects of reorganizing a network industry's vertical structure. In this industry, an upstream monopolist operates a network used as an input to produce horizontally differentiated final products that are imperfect substitutes. Three potential pitfalls of...

We study the role of vertical structure in determining generating capacities and retail prices in the electricity industry. Allowing for uncertain demand, we compare three market configurations: (i) integrated monopoly, (ii) integrated duopoly with wholesale trade, and (iii) separated duopoly...

This paper studies how competition and vertical structure jointly determine generating capacities, retail prices, and welfare in the electricity industry. Analyzing a model in which demand is uncertain and retailers must commit to retail prices before they buy electricity in the wholesale...
