The petroleum refining industry has changed over the past decades from one in which capacity primarily served local and regional markets to one in which trade in refined petroleum products has become more widespread. We investigate the hypothesis of increasing globalization by examining the...

This study analyzes industrial interfuel substitution in an international context using a large unbalanced panel dataset of 63 countries. We find that compared to other countries fossil fuel producing economies have higher short-term interfuel substitution elasticities. This difference increases...

Economic theory suggests that gasoline retail markets are prone to collusive behavior. Oligopoly market structures prevail, market interactions occur frequently, prices are highly transparent, and demand is rather inelastic. A recent sector inquiry in Germany backed suspicions of tacit collusion...

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...

Regular and asymmetric gasoline price cycles are observed in a number of countries. While most studies found that such price cycles are well characterized by the theoretical Edgeworth price cycle, some studies suggest alternative explanations. This paper contributes to this literature by being...

This paper studies the target pricing zone (TPZ) hypothesis for crude oil by examining price clustering in the dollar digit. It is hypothesized that price clustering occurs within an established TPZ if OPEC is able to defend the upper and lower bounds through output changes. The results show...

We use a novel data set with exact price quotes from virtually all German gasoline stations to empirically investigate how a temporary variance in local market structure - induced by restricted opening hours of specific players - affects price competition. We focus on stations selling gasoline...

Do events in the natural gas market cause repercussions in the crude oil market? This paper studies linkages between the two markets using high-frequency, intraday oil and gas futures prices. By analyzing the effect of weekly oil and gas inventory announcements on price volatility, we show a...

In this article, we show how the copula-GARCH approach can be appropriately used to investigate the conditional dependence structure between the crude oil and natural gas markets as well as to derive implications for portfolio risk management in extreme economic conditions. Using daily price...
