This paper develops a methodology to test whether recent developments on world oil markets are in line with the hypothesis of efficient markets. We treat the joint hypothesis problem as stated by Fama (1970), Fama (1991), that market efficiency can only be assessed in conjunction with a price...

This study investigates the role of heterogeneous agents in oil markets and tests tales of speculators in oil price formation. Results obtained from using a non-linear heterogeneous agent model suggest that oil market prices are driven by different groups of speculators, namely fundamentalists,...

By interlinking power systems, significant welfare gains can be achieved. However, different approaches for coupling electricity markets exist. A recent development in this field is the implementation of flow-based market coupling (FBMC) in Central Western Europe (CWE). Indeed, FBMC has proven...

In this article we discuss welfare-optimal capacity allocation of different electricity generation technologies available for serving system demand. While the classical peak load pricing theory derives the efficient portfolio structure from a deterministic marginal production cost curve ("merit...

Deterministic capacity planning problems in electricity systems can be solved by comparing technology specific long-term and short-term marginal costs. In an uncertain market environment, Mean-Variance Portfolio (MVP) theory provides a consistent framework to balance risk and return in power...
