    Evidence of Market Power in the Atlantic Steam Coal Market Using Oligopoly Models with a Competitive Fringe

    Before 2004 South Africa was the dominant steam coal exporter to the European market. However a new market situation with rising global demand and prices makes room for a new entrant: Russia. The hypothesis investigated in this paper is that the three incumbent dominant firms located in South Africa and Colombia reacted to that new situation by exerting market power and withheld quantities from the ...

    Renewable Electric Energy Integration: Quantifying the Value of Design of Markets for International Transmission Capacity

    Integrating large quantities of supply-driven renewable electricity generation remains a political and operational challenge. One of the main obstacles in Europe to installing at least 200 GWs of power from variable renewable sources is how to deal with the insufficient network capacity and the congestion that will result from new flow patterns. We model the current methodology for controlling congestion ...

    Merger Efficiency and Welfare Implications of Buyer Power

    This paper analyzes the welfare implications of buyer mergers, which are mergers between downstream firms from different markets. We focus on the interaction between the merger's effects on downstream efficiency and on buyer power in a setup where one manufacturer with a non-linear cost function sells to two locally competitive retail markets. We show that size discounts for the merged entity has no ...

    Removing Cross-Border Capacity Bottlenecks in the European Natural Gas Market: A Proposed Merchant-Regulatory Mechanism

    We propose a merchant-regulatory framework to promote investment in the European natural gas network infrastructure based on a price cap over two-part tariffs. As suggested by Vogelsang (2001) and Hogan et al. (2010), a profit maximizing network operator facing this regulatory constraint will intertemporally rebalance the variable and fixed part of its two-part tariff so as to expand the congested ...

    The Globalization of Steam Coal Markets and the Role of Logistics: An Empirical Analysis

    In this paper, we provide a comprehensive multivariate cointegration analysis of three parts of the steam coal value chain - export, transport and import prices. The analysis is based on a rich dataset of international coal prices; in particular, we combine data on steam coal prices with freight rates, covering the period December 2001 until August 2009 at weekly frequency. We then test whether the ...

    Infrastructure, Regulation, Investment and Security of Supply: A Case Study of the Restructured US Natural Gas Market

    In this paper, we discuss the relationship between infrastructure regulation and investment in light of the emerging "security of supply" debate. We approach the subjectby surveying the literature of the past two decades, especially examining the interactions among restructuring, regulation, and investment. The empirical section of this paper relies on case studies of the relationship between the regulatory ...

    Where Are the Industrial Technologies in Energy-Economy Models? An Innovative CGE Approach for Steel Production in Germany

    Top-down computable general equilibrium (CGE) models are used extensively for analysis of energy and climate policies. Energy-intensive industries are usually represented in top-down economic models as abstract economic production functions, commonly of the constant-elasticity-of-substitution (CES) or translog functional form. This study explores methods for improving the realism of energy-intensive ...
