The dual relationship between parameters of normalized quadratic cost and profit functions is determined when firms can implement market power on the output market. An approach is developed to test the market power by comparing the profits of a firm with and without market power. Simulations...

The estimation of optimal support boundaries under the monotonicity constraint is relatively unexplored and still in full development. This article examines a new extreme-value based model which provides a valid alternative for completely envelopment frontier models that often super from lack of...

The purpose of this study is to analyze the cost efficiency of electricity distribution systems in order to enable regulatory authorities to establish price- or revenue cap regulation regimes. The increasing use of efficiency analysis in the last decades has raised serious concerns among...

The pollution haven effect reflects the idea that stricter environmental policies foster the relocation of polluting activities and imports of pollution-intensive products. This paper develops a new approach for testing this effect for imported intermediate materials. It adds to the existing...
