This paper analyses whether prices and trade-flows in the international market for metallurgical coals were subject to non-competitive conduct in the period 2008 to 2010. To do so, I develop mathematical programming models – a Stackelberg model, two varieties of a Cournot model, and a perfect...

The mathematical formulation of a strategic Eurasian natural gas market model is presented. The model represents horizontal oligopolistic relationships among producers, bilateral market power between producer (Russia) and transit (Ukraine) countries, detailed transport constraints, and operation...

Motivated by recent interventions by the states of New Jersey and Maryland and the introduction of PJM's Minimum Offer Price Rule (MOPR) for capacity markets, we analyze the impact of subsidized government investments in electrical generation on electricity markets. We extend the model of Joskow...

In this paper, we analyze the strategic function of gas storage focusing on how gas storage decisions impact competition between gas companies on both spot and downstream markets. Using a two-tier oligopolistic structure, we first show that gas storage is actually used strategically even in a...

In this paper we measure the impact of regulatory measures which affected the Spanish electricity wholesale market between 2002 and 2005. Our approach is based on the fact that regulation changes incentives for firms and therefore their market behavior. In the absence of any regulation, firms...

Renewable portfolio standard (RPS), which requires a certain percentage of electricity production from renewables, has received considerable attention. One emerging issue is the possibility of strategic behavior in the renewable energy certificate/credit (REC) market, and its spillover effects...

In this paper we apply a model of optimal bidding behavior to the Italian wholesale electricity market under three hypotheses: i) costs of generation are private knowledge, ii) firms can be vertically integrated, and iii) firms can sell part of their production in advance with bilateral...

Among the many reasons policy makers across the world have sought to supplement fuel supplies with ethanol-blended fuels are the cited environmental benefits that come with replacing a fossil-fuel with a cleaner burning alternative. Dual-blend ethanol mandates, in which multiple ethanol blends...

The Federal Energy Regulatory Commission may grant market-based rates to oil pipelines in the U.S. upon a showing that they lack market power. The Commission defines market power as the ability to profitably increase price above the competitive level for a significant period. Because comparing...

The capacity of the transmission network determines the extent of integration of a multi-national energy market. Cross-border externalities render coordination of network capacity valuable. Is it then optimal to collect regulatory powers in the hands of a single regulator? Should a common system...
