Nordhaus develops a general equilibrium model to determine the path of prices of energy resources and efficiently allocate four main energy resources (petroleum, coal, natural gas, and uranium-235) over time, space and different energy demand categories. Additionally, he explores whether the resulting optimal price paths are close to market-determined ones. His formulation of the model follows a standard dynamic optimization problem; and thus the price paths associated with his optimal solution (shadow prices for resources over time) are interpreted as rents that a competitive market would impute to scarce resources (Hotelling’s Rule). The main empirical conclusion of the paper is that the calculated prices are not very far from the actual market ones, with the exception of petroleum products and coal. According to natural resources economic theory, in an efficient allocation, resources are extracted such that the stream of discounted profits (from selling a unit of the resource at each time period) is maximized. The time horizon, nevertheless, Nordhaus considers, is a very long one (200 years). Furthermore, in discounting future values, Nordhaus applies a constant interest rate. The following paragraphs discuss how both these aspects in natural resources modeling have been questioned by economists. Economists have argued extensively, in the context of Net Present Value criterion (in Cost Benefit Analysis, CBA), over the choice of the appropriate discount rate. The conclusion of the debate is that the choice of the discount rate depends on the extent to which a project is funded by consumption or private investment. For example, if the project is entirely funded by consumption, then it has been argued that it should be discounted by the Social Rate of Time Preference; while if it is funded by displaced investment, then it should be discounted by the Private Return to investment (other economists have argued we may want to use a mix of these two). In any case, the standard practice has been to use the same value for discount rate across all time periods, the latter thus leading to exponential discounting. Nevertheless, the classic constant discount rates have been proven to perform well in short–medium time horizons. However, over the recent years, economists have shown that discounting at a constant positive rate is problematic, particularly in long-run environmental problems (such as climate change, nuclear waste, or biodiversity loss). The reason is that a constant discount rate over time discounts so heavily the welfare (costs or benefits) of future generations, such that it appears small (in present value terms). The

The core contribution is to map the development of the literature in digital sustainability over time and across various clusters. Through VOSviewer analysis, we identify the main keywords used by the literature; the countries from which most of the literature is emerging; the most influential authors working in the field; and, their impacts by observing their citations and networks. Moreover, through CitNetExplorer analysis, we track the development of the field over time, i.e., identify key publications and divide those into clusters. The analysis finds a much more developed coverage of digital sustainability in the scholarship of management/business and therefore reveals a clear need for greater exploration of the sociological and economic aspects of digital sustainability. We argue that more ro...

Ya en tiempos de Aristoteles, a los pensadores sociales expresaban les preocupaba que la busqueda de beneficios condujera a la deshumanizacion de quienes participan en los intercambios economicos, una tema que tambien trataron los pensadores fundacionales de las ciencias sociales modernas, como Karl Marx y Max Weber. Este articulo prueba el potencial del uso de MSC para reducir esta deshumanizacion, que ahora se situa en un contexto social mas amplio, el del capitalismo global contemporaneo. Comenzando con una revision de los tipos de MSC, el articulo toma en consideracion los objetivos y metas de las MSC en todo el mundo. Hay motivos para ser optimistas y pensar que las MSC pueden reducir los aspectos negativos del intercambio financiero tradicional al utilizarse en otros de caracter periferico y/o excluidos de l...

As far back as Aristotle, social thinkers have expressed concern that the pursuit of profit for its own sake leads to the dehumanization of those participating in economic relations, a concern which was echoed in the work of foundational thinkers in the modern Social Sciences, for example Karl Marx and Max Weber. This article probes the scope of CC use to alleviate such dehumanization, situated within this broader social context of contemporary global Capitalism. Beginning with a review of the types of CCs, this paper considers the objectives and goals of CCs worldwide. Indeed, there is room for optimism that CCs may ease negative aspects of traditional financial exchange by serving those on the fringes of and/or excluded from formal economies, and without necessarily competing with public or private traditional banking institutions. The paper conclude...

This paper explores the biases that occur if one estimates conventional models, such as Poisson and negative binomial, ignoring truncation or/and stratification. We conduct three sets of simulations by artificially generating observations on trips using the covariates from a study of beach recreation at Lake Erie (Haab and McConnell, 2003). Preliminary evidence reveals that estimation of models for on-site samples is complex, can be computationally burdensome, and can result in large biases. However, we also find that in some cases, relatively simple models perform well, even though they do not

The resulting allocation should be economically efficient, social equitable and acceptable, and environmentally sustainable. The main background concept guiding the identification of such an allocation is that of the 'Total Economic Value (TEV)' of water resources, which derives from the ecosystem goods and services that water resources provide the economy and society. In this chapter we present the state-of-the-art with regards to estimating TEV of water resources and explain how these estimations can facilitate the design and implementation of the different European policies in relation to mitigation of different forms of water stress.

I shall always keep in mind what you, pretty soon, taught me, i.e., that many peopleincluding me-do not realize what they have learned although they think they do. I am afraid I still have a long way before I stop making a hundred turns about a point, wearying myself and wearying my readers. I have enjoyed every discussion with you. You are all over my Ph.D. memoirs. I will miss you saying: "Mr. Reppas: Stop making those faces and listen to me!" To Ted McConnell, thank you for encouraging me to choose this research topic, and helping me with different stages of the calibration. It is clear to me that your pretence, sometimes, of ignorance, is nothing less than your ability to speak to every person to his own language. To Tigran Melkonyan, thank you for supporting and inspiring me at the early steps of my research; I could not have set out without our discussions, and without you pointing out the relational contracts literature to me. Most of all, thank you for showing me how to trust young people, and how to be a caring professional. You have set these standards too high for me. To Andreas Lange, thank you for your patience in reading previous drafts of this research, and listening to my non-structured arguments. Having you around to bother with questions, made the whole research process easier. To Doug Lipton, thank you for your genuine enthusiasm every time I approached you for information regarding fisheries. On many occasions, you devoted personal time and effort to make my problems your problems; and provided immediate solutions, as well as relief, to me. To Howard Leathers and Virginia Haufler, thank you for agreeing-without hesitation and on such a short notice-to become members of my committee. Thank you also for giving me feedback on my topic. To Eirini, thank you for your continuous patience for more than 36 months now. Little did I know, when I informed you that this research needed only 6 more months to be completed, that it would take me all this time. You have been my second life throughout these last years. To my parents, Vassilis and Eleni, as well as my sister, Olympia, thank you for always keeping faith in me. iv To Barbara Zanou, thank you for your endless phone calls supporting and encouraging me at difficult moments; for sharing your personal experiences in pursuing a Ph.D.; and for grasping my intends, even if I was thousands of miles away.
