We analyze market dynamics under Bertrand duopoly competition in industries with network effects and consumer switching costs. Consumers form installed bases, repeatedly buy the products, and differ with respect to their switching costs. Depending on the ratio of switching costs to network...

Mergers in imperfectly segmented markets

Baake, Pio; Wey, Christian - 2009

We present a model with firms selling (homogeneous) products in two imperfectly segmented markets (a "high-demand" and a "low-demand" market). Buyers are mobile but restricted by transportation costs, so that imperfect arbitrage occurs when prices differ in both markets. We show that equilibria...

Supplier fixed costs and retail market monopolization

Caprice, Stéphane; Schlippenbach, Vanessa von; Wey, … - 2014

Considering a vertical structure with perfectly competitive upstream firms that deliver a homogenous good to a differentiated retail duopoly, we show that upstream fixed costs may help to monopolize the downstream market. We find that downstream prices increase in upstream firms' fixed costs...

The dynamics of global crude oil production

Zaklan, Aleksandar; Zachmann, Georg; Neumann, Anne - 2010

We analyze the dynamic effect of prices and price volatility on current oil production, both on the level of country groups and the major individual producer countries. A comprehensive dataset at monthly frequency allows us to include a rich lag structure while controlling for key global and...

Unionisation Structures and Firms' Incentives for Productivity Enhancing Investments

Haucap, Justus; Wey, Christian - Royal Economic Society - RES - 2003

This paper examines how unionisation structures that differ in the degree of wage centralisation affect firms' incentives to increase labour productivity. We distinguish three modes of unionisation with increasing degree of centralisation. (1) "Decentralisation" where wages are determined...

The comparison between ad valorem and unit taxes under monopolistic competition

Schröder, Philipp J. H. - 2003

This paper shows that the welfare dominance of ad valorem over unit taxes under imperfect competition, extends to the Dixit-Stiglitz framework with differentiated products, entry and love of variety. This contrasts against findings by Anderson et al. (J Public Econ, 2001) made in a similar...

How to turn an industry green : taxes versus subsidies

Dröge, Susanne; Schröder, Philipp J. H. - 2003

Environmental policies frequently target the ratio of dirty to green output within the same industry. To achieve such targets the green sector may be subsidised or the dirty sector be taxed. This paper shows that in a monopolistic competition setting the two policy instruments have different...
