The Genuine Progress Indicator (GPI) was designed to reveal the economic, social, and environmental trade-offs associated with conventional economic growth as traditionally measured by Gross Domestic Product (GDP). Although originally designed for use at the national scale, an interest has developed in the United States in a state-level uptake of the GPI to inform and guide policy. This study presents the first fifty-state estimate for U.S. GPI in order to address questions over its design, implementation, and ultimate potential as a tool to guide state-level economic policy. Following a review of the current state of analysis and critique of GPI, we provide an overview of methodology and database development. Results are then presented, including discussion of lessons learned through a fifty-state application. The paper concludes with suggestions for further research and next steps to consolidating a consistent methodology. [ABSTRACT FROM AUTHOR]

While the number of farm-level sustainability assessment tools is growing rapidly, concerns are raised on whether the assessment results of different tools present similar and valid conclusions about the sustainability performance of farms. In this paper we analysed the thematic scope of sustainability assessment tools, and compared assessment results from sustainability assessment tools. A coverage analysis of four tools (RISE, SAFA, PG and IDEA) demonstrated the diversity in approaches to assess sustainability at farm level. Tool developers select different (sub)themes and indicators, and apply different methods for measurement and aggregation of scores. This variability in approaches results not only in different tools, but can also result in different conclusions on the sustainability performance of farms. Decisions made in the development of a sustainability assessment tool need to be transparent to understand and explain the results of a tool and support farmers in a sustainable development of their farm. To improve the transparency in sustainability assessment tools we presented a framework describing decisions made in the development of a tool. An increased transparency in sustainability assessment tools can reduce the risk on distorted assessment results and actions, and contribute to the trust and relevance of future sustainability assessments.

Abstract: Recent years have seen increasing awareness of the deficiencies of conventionally defined national income as a measure of a nation''s overall economic performance. Alternative measures have been proposed involving either the modification of national income accounting conventions, or the abandonment of national income itself in favour of something such as the Genuine Progress Indicator, GPI. However, such alternatives, like national income itself, all involve the use of monetary valuation for aggregation. This paper proposes a new approach to the measurement of national economic performance, which follows naturally from ecological economics as the study of economic activity rooted in a proper appreciation of its material circumstances, and which does not involve using prices for aggregation. The paper gives some results for three variants of the new approach, and compares and discusses them. While this new approach does not purport to provide a single definitive assessment of the sustainability of current economic activity, which is an infeasible goal, it could provide useful inputs to relevant research activity, and to policy analysis and debate.

A semi-empirical endogenous growth theory was proposed by the authors in 2005. It is based on a model of the economy as a two-stage materials/energy processing system. Growth is simulated by a two-parameter production function with two traditional factors, labor and capital, and a non-traditional factor, namely ‘useful work’. The non-traditional factor is calculated from primary energy inputs multiplied by an empirically estimated average energy conversion efficiency, which is a function of changing technology over time. This model ‘explains’ past US growth from 1900 through 1973–74 with satisfactory accuracy but it slightly underestimates subsequent growth (i.e. it leaves a small unexplained but increasing residual) for the period after 1975. However, by subdividing capital stock into traditional and ICT components, we are able to extend the theory to explain US economic growth accurately. In this paper we also extend the results to Japan. The revised production function has only three independent parameters. The new model also has implications for future economic growth, energy and environmental policy that differ significantly from the traditional growth theory. These implications are discussed briefly.

Abstract: This paper takes as a starting point a combination of an input–output model with a national Ecological Footprint account for Germany in the spirit of Wiedmann et al. [Wiedmann, T., Minx, J., Barrett, J., Wackernagel, M., 2006. Allocating ecological footprints to final consumption categories with input–output analysis. Ecological Economics. 56, 28–48]. Footprint as well as Biocapacity is dealt with at the industry level. Gross output of each industry and final demand for each industry can then be split up into a share that is reconcilable with Biocapacity and another share that corresponds to the ‘Ecological Deficit’. The Ecological Footprint concept is extended in this study by introducing the additional biocapacity necessary for sustaining the given level of economic activity. It is assumed that each industry had to rent the corresponding areas and to apply a given technology in order to make this additional land biophysically productive. That results in an additional technology for each industry leading to an increase in costs and prices. The new price level is directly linked to the share of output that corresponds to Biocapacity overshooting, which is defined by the ‘Ecological Deficit’. Economic indicators can be derived by measuring the income difference brought about by the price increase. This difference corresponds to a Ricardian rent which is due to resource constraints on output growth. [Copyright &y& Elsevier]

Abstract: This paper proposes that the current growth-oriented exposition of the knowledge economy in literature is not only monistic but also partial. The mainstream''s persistent emphasis on knowledge and economic growth and its neglect of knowledge and other critical issues (such as promoting wealth equalities and environmental conservation) lead to a paucity in terms of the variety of knowledge in the global knowledge commons, which will not fulfill the goal of sustainable development. To maintain a sustainable society with an efficient use of resources, it is necessary to achieve a more equitable distribution of wealth. This type of question, however, continues to be ignored and remains unanswered in both the Austrian analysis of the knowledge problem and the mainstream exposition of the knowledge economy. In this regard, John Stuart Mill''s concept of the stationary state is in line with contemporary analysis of a sustainable society and is worth further review. [Copyright &y& Elsevier]

Abstract: The empirical environmental Kuznets curve (EKC) literature is vast but far from conclusive. Many authors have analysed the existence of an EKC for various pollutants. Others have used the EKC framework to identify country characteristics that help to explain the income–environment relationship. In this framework environmental degradation is analysed using a second or third order polynomial in income and a limited number of control variables. Some authors question whether this standard framework is appropriate. This paper proposes an alternative to study the specific characteristics of countries that have experienced economic growth and an improving environment at the same time. We estimate a binary response model and find an EKC-like relation between the probability that a country''s environment improves with economic growth and per capita GDP. Our evidence further suggests that the level of environmental damage is an important explanatory variable. We also confirm the importance of an open political system. These results indicate that the binary response model could be a valuable alternative to test which country specific characteristics are associated with a negative IER. [Copyright &y& Elsevier]
