Productivity measures ignoring environmental effects may give misleading information on total productivity growth. Further, business cycles in the form of capacity utilization may also significantly influence productivity measures. In this paper, we develop an overall Malmquist productivity...

Although environmental regulations may imply a cost increase on firm's conventional input factors, such regulations could stimulate the incentives to improve factor productivity. Productivity measures including indicators capturing environmental improvements may also show higher or lower...

Productivity measures ignoring environmental effects may give misleading information on total productivity growth. Further, business cycles in the form of capacity utilization may significantly influence productivity measures. We develop an overall Malmquist productivity index and decompose...

Over the last few decades, several instruments have evolved to deal with similar energy and environmental challenges. For instance, the economic literature prescribes separate tax or cap-and-trade systems to internalize negative environmental externalities and subsidies to internalize positive...

In 2002/2003, the Nordic hydro-dominated power market faced a short-term supply shock. In autumn, precipitation and inflow were unusually low. As a result, there were record high prices in the following winter. Questions were raised whether the deregulated market creates sufficient incentives to...

In many countries hydropower constitutes a large share of the electricity producing capacity. In the earlier regulated electricity markets, production capacities exceeded demand due to security of supply concerns. The present deregulated markets base investments upon profitability alone, and...

Many economists maintain that environmental regulations hamper productivity growth. However, recently, an opposing view has gained advocates. Indeed, it has been suggested that the empirically detected inverse relationship between environmental regulations and productivity growth is an almost...

Although most production activities involve multiple outputs, econometric models of production or cost functions normally involve only one single homogeneous output. The aim of this paper is to test the hypothesis that a multiproduct specification is superior to a model with a single homogenous...

The Integration Pollution and Prevention Control (IPPC) directive from the European Union implies that the regulatory emission caps should be set in accordance with each industry’s Best Available Techniques (BAT). The directive is under implementation in Norway, and it represents a refocus of...
