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 ''short-side...

Context: Azerbaijan's vocational education and training (VET) system has undergone a significant reform, culminating in the enactment of the Law on Vocational Education in 2018. Despite not being a member of the European Union (EU) and lacking formal political, economic, or cultural alignment...

This paper analyzes a monopoly platform's joint pricing and investment decisions in the canonical two-sided market model of Armstrong (2006). Participants are heterogeneous in outside options and derive both stand-alone benefits from joining the platform, and network benefits from interacting...

This paper analyzes a monopolistic market with a continuum of consumers in the linear case. Consumers are vertically differentiated by a one-dimensional preference for quality, and the monopolist is allowed to offer a menu of quality-price pairs. The analysis shows that, in the linear case, the...

Why does industrialization in some cases generate social consolidation and in other cases political conflict? This paper argues that the answer depends on how industrial finance is allocated. I develop a dynamic political-economy model in which the government channels external liquidity into...

The aim of this article is to provide elements to answer the question of how and when the situation the situation of depletion of a non-renewable, non-durable resource would be reached. To this end, a nonlinear programming model is used under the assumption that the resource is in the hands of a...

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 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...

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...

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...

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 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...

This paper introduces a novel ratio-based framework for analyzing how consumer heterogeneity translates into product differentiation in vertically structured monopoly markets. We consider a monopolist facing a continuum of consumers and a strictly convex production cost function and identify...

We develop a bilateral monopoly model with bargaining that accommodates upstream monopsony and downstream monopoly power. In equilibrium, the ''short-side...

We study monopolistic certification in a buyer-seller relationship, explicitly distinguishing between its role as a device for screening versus acquisition. As a screening device, certification discloses soft information about a seller's private information. As an acquistion device,...

We consider a screening problem in which a data seller offers a dynamic payment schedule for a sequence of experiments to a privately informed buyer. Different buyer types face different expected costs for the same payment schedule. This payment gap can be optimized to reduce information rent....
