The digital transformation of media ecosystems, characterised by algorithmic curation, platform monopolies, and AI-generated content, poses unprecedented challenges to liberal democracies. This paper develops an updated ordoliberal framework to identify four systemic risks: (1) erosion of...

Questions about market power have become salient in macroeconomics. We consider the role of institutional structures in addressing these within a dynamic general equilibrium framework. Standard models account for monopoly profits as a lump-sum transfer to the representative agent. We label this...

Privacy regulations like the General Data Protection Regulation aim to empower consumers with greater transparency and control over their personal data. In response, firms may exercise price discrimination in the form of versioning. This paper studies how these two aspects of privacy regulation...

Die Infrastruktur der deutschen Autobahnen ist von zentraler Bedeutung für den Wirtschafts-verkehr, den Tourismus und die Mobilität der Bürgerinnen und Bürger. Ein zentraler Bestandteil dieser Infrastruktur sind Haltepunkte entlang der Fernstraßen. Autobahnraststätten und Autohöfe dienen...

Die Digitalisierung führt zu einer anhaltenden Transformation des Medienökosystems. Die globale Macht von Plattformmonopolen und die zunehmende Bedeutung von künstlicher Intelligenz sind nur zwei Beispiele für die Notwendigkeit eines Updates der Medienökonomik. Wichtige Ziele sind der...

This study investigates how government policies affect the market environment and enterprise practices. We conduct a quasi-natural experiment, with a treatment group based on enterprises' investment circumstances to examine the impact of the Fair Competition Review System (FCRS) on enterprise...

I examine the pricing behavior of municipal and private firms in the unregulated Swedish district heating market, characterized by geographically bounded local monopoly networks. Conditional on exogenous cost factors, private firms charge on average seven percent higher prices compared to their...

Change ownership reforms for electric cooperatives (ECs) have once again attracted policymakers' interest due to current e!orts in expediting their privatization. This note serves as input to this ongoing conversation using the lens of competition. We argue that unchecked consolidation -...

This paper considers a delegation game between one multi-input firm and one single-input firm engaging in Cournot competition in the downstream market. Both firms purchase a standard input from a core input supplier, and the multi-input firm also needs a supplementary input provided by an...

This article bridges monopoly, monopsony, and countervailing power theories to analyze their welfare implications in a vertical supply chain. We develop a bilateral monopoly model with bargaining that accommodates upstream monopsony and downstream monopoly power. In equilibrium, the...

We revisit the classic chain-store paradox by introducing a novel element: the arrival of exogenous, public signals about the incumbent's private type over time. As the horizon lengthens, two opposing forces come into play. On one hand, standard reputational incentives grow stronger; on the...

This article presents neo-Kaleckian macroeconomic models that are intended for under-graduate instruction at the introductory and intermediate levels. The neo-Kaleckian approach incorporates markup pricing, monopoly power, and income distribution into a demand-driven macro model for short-run...

Platform pricing may be connected to antitrust risks, which a company can face under excessive or predatory price scrutiny when the platform is recognized as dominant in the market. Since Federal Antitrust Service of Russia (FAS Russia) prefers price-cost comparison when studying excessive or...

This study delves into a market characterized by vertical product differentiation. Product qualities are represented on a one-dimensional interval scale. The research investigates the equilibrium within a monopoly scenario, considering a production cost that is strictly convex. The monopoly...

Purpose of the article: A correct understanding of mechanisms governing the market is crucial for proper functioning of the labour market. The market structure phenomenon, so far most frequently described in the imperfect competition theory as a bilateral monopoly, occupies a unique position in...

Labor economics often assumes that wages w are equal to the marginal revenue product of labor MRP L. However, recent literature has shown that firms' market power allows them to pay wages substantially below marginal productivity. The markdown (MRP L - w)/w is our preferred measure of firms'...

In this paper, I explore the relationship between wage bargaining and capital accumulation by developing a differential game in which a monopolistic union sets the wage of its members by taking as given the optimal employment strategy of a representative firm and the way in which capital is...
