The generation of unintended residuals in the production of intended outputs is the key factor behind our serious problems with pollution. The way this joint production is modelled is therefore of crucial importance for our understanding and empirical efforts to change economic activities in...

How can we design more sustainable industrial and urban systems that reduce environmental impacts while supporting a high quality of life for everyone? What progress has been made towards reducing resource use and waste, and what are the prospects for more resilient material-efficient economies?...

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...

In this paper we propose a stochastic formulation of the materials balance condition which imposes physical constraints on production technologies. The estimation of the model involves a composed error term structure that is commonly applied in the literature on stochastic frontier analysis of...

On June 25, 2013, President Obama announced his plan to introduce carbon dioxide emission standards for electricity generation. This paper proposes an efficiency analysis approach that addresses which mission rates (and standards) would be feasible if the existing generating units adopt best...

Lakes throughout the world recently are facing serious problem which lead to its extinction. Integrating conservation and tourism in lakes and it surrounding area offer new opportunities for environment, development and economic growth in harmony. The aim of the research is to identify spatial...

This study explores the relationship between energy and material efficiency innovations (EMEIs) and innovation strategies employed by manufacturing firms to develop their process innovations. Firms may mainly develop process innovations in-house, let them mainly develop by other enterprises or...

Die entscheidungstheoretische Erweiterung der Produktionstheorie nach DYCKHOFF stellt auch erweiterte Anforderungen an Input/Output-Graphen als Produktionsmodell zur Abbildung von Prozessstrukturen. Der vorliegende Arbeitsbericht erläutert in seinem ersten Teil die wichtigsten Anforderungen und...
