Studies of productivity growth of institutions of higher education is of interest for two main reasons; education is an important factor for productivity growth of the economy, and in countries where higher education is funded by the public sector accountability of resource use is of key...

There are plans of a substantial increase in the construction of renewable power in Scandinavia in the coming 10 years. The Nordic countries operate a common wholesale market, Nord Pool. Intermittent power (wind power, solar and small-scale hydro power) is stochastic and therefore needs other...

The materials balance principle points to the crucial role of material inputs in generating residuals in production processes. Pollution modelling must be of a multi-output nature. The most flexible transformation function in outputs and inputs used in textbooks is too general to make sense in...

The modelling of the interaction between production activities and the natural environment requires formulating a multioutput production function for intended and unintended outputs. The key feature when modelling joint production of intended outputs and unintended residuals is that the latter...

Research on productive efficiency at the firm level has developed as an important and active strand of research the last decades, both within operations research, management science and economics. However, the interests pursued within the fields have had some differences regarding sound...
