International fish trade is growing, and fish exports represent an important source of foreign currency for many countries. For a few countries the exports are also an essential part of the economy. We revisit the seminal paper of Richardson (1978) that addresses the issue of exchange rate...

Relationships between prices are of interest when testing for market integration as well as analyses of supply chains. A feature that has received little attention is that if two supply chains are linked by market integration at some stage, then the whole supply chain will be linked....

When natural gas prices are subject to periodic decoupling from oil prices, for instance due to peak-load pricing, conventional linear models of price dynamics such as the Vector Error Correction Model (VECM) can lead to erroneous inferences about cointegration relationships, price adjustments...

In this paper we are investigating how production risk may influence the way a risk averse producer like a subsistence farmer chooses optimal input levels. Risk averse producers will take into account both the mean and the variance of output, and therefore we expect them to choose input levels...

In this paper we apply the Bresnahan-Lau (1982) model to test for market power in the European distribution of salmon. In this particular setting, the model also incorporates a test of whether dumping takes place over time. Utilising data at the import level, derived demand equations are...
