This study analyses farm level economic impacts of biomass production from perennial crops including Arundo donax L. (arundo), Miscanthus x giganteus (miscanthus), Panicum virgatum L. (switchgrass) and Cynara cardunculus L. (cardoon). Regional biomass supply curves are estimated with a dynamic, multi-farm, mathematical programming model. Micro-economic data for the model are generated from farm surveys covering 52 farms containing a total of 400 parcels, in Central Greece. The study also examines the potential effects of the Common Agricultural Policy reform in 2003 on regional biomass supply. Simulations show that the policy reform toward decoupled subsidies lowers the cost of biomass between 15 and 25 euro per tonne. Switchgrass appears to be the most attractive option, followed by cardoon and miscanthus. Due to high specific machinery cost, arundo is never preferred. Relative to the agricultural policy setting of Agenda 2000, the biomass potential increases more for farms of small economic size and farms with a higher share of cotton. © 2010 Elsevier Ltd. Source

The objective of this paper is to estimate productivity changes after the inclusion of quality variables for a panel of Greek public hospitals during the period 2002-2007. We measure hospital productivity and quality changes through a non-parametric estimation of the quality adjusted Malmquist productivity index by using the percentage of survival after admissions as a proxy of hospital care services quality. Even though the empirical results indicate on average deterioration both in productivity and quality there is considerable variation among the sample hospitals. © 2010 Springer-Verlag. Source

This is an empirical study on the growth impact of Information and Communication Technologies using industry-level data for the US and the EU industries over the period 1980-2000. A panel data approach is employed to estimate the ICT effect using the system GMM and the pooled mean group panel data estimators. The results vary depending on the period, the region, and the type of industry considered. The GMM estimates suggest a significant ICT effect on growth during the 90s both in the US and in the EU. This effect for the EU was strong in the early 90s and weakened afterwards, as opposed to the US where it strengthened in the late 90s. The results of the pooled mean group estimator confirm that the long run growth contribution of ICT was significantly positive in the industries of both regions and over the entire period 1980-2000. However, it seems that the productivity effects of ICT are mainly present in the industries which are either ICT producers or heavy ICT users. © 2010 Elsevier B.V. Source

Environmental Modeling and Assessment | Year: 2013

This paper examines the problem of asymmetric information in financial markets due to a lack of essential environmental information. The literature indicates that asymmetric information generates various problems for the actors of financial markets such as incomplete information for investment decisions and lending procedures, misallocation of financial market funds, the underestimating of stock price securities, and poor environmental risk management choices. To this end, this paper develops a game-theoretic approach to examine both the persistent nature of asymmetric information caused by the absence of accurate environmental information and to indicate how a well-organized, trustworthy, internationally agreed auditing accounting certification scheme could play a critical role in limiting the magnitude of this problem. © 2013 Springer Science+Business Media Dordrecht.

Biofuels, Bioproducts and Biorefining | Year: 2010

Nowadays, the cultivation of energy crops is, in most cases, directly or indirectly subsidized at EU and global levels. However, their financial viability, i.e. sustainable profitability in the absence of subsidies, is not too remote any more given the increasing cost of fossil fuels, pressing environmental concerns, and the rapid technological progress in the renewable energies field.This analysis presents a number of case studies examining the viability of the most promising oil and sugar crops for the production of first-generation biofuels. The presented outputs of this work indicate that today, the viability of energy crops, such as rapeseed (Brassica napus), Brassica carinata, sunflower and sweet sorghum, can be attained under favorable conditions. Detailed cost analysis of these crops in various European regions leads to the estimation of profitability and illustrates their financial profile. Comparative analyses are made with the most widespread conventional food crops, such as wheat and maize.The results of the study have shown that first-generation oil producing crops in Europe are worth cultivating under current support regimes and under favorable market conditions. In view of the prevailing instability in the price of crops, the farmer has to make decisions on a rather short-term basis. Sweet sorghum in southern Europe appears to be a very promising proposition for the production of bioethanol, as it appears much more efficient than cereals and sugarbeets, which are used today in the bioethanol industry. © 2010 Society of Chemical Industry and John Wiley & Sons, Ltd.
