estimating residential demand for electricity in greece abstract this paper examines the residential demand for electricity in greece the issues of structural stability price and income sensitivity of both long and short run residential demand for electricity in greece were examined employing monthly data over the period 1986 1999 the long run residential demand for electricity is estimated taking into account changes in weather conditions weighted by the size of the population employing multivariate framework analysis a long run residential demand function for electricity sensitive to real income price level and weather conditions is found to exist and the importance of short run deviations is presented using vector error correction model vecm estimation the empirical evidence suggests the presence of a stable residential demand for electricity in greece both in the long and short run periods and the policy implications of such a relationship are presented

hybrid r d we develop a model of r d collaboration in which individual firms carry out in house research on core activities and undertake bilateral joint projects on non core activities with other firms we develop conditions on the profit functions of the firm under which r d investments in different projects of a firm are complementary we show that this condition is met by standard price and quantity setting oligopoly models we then study the relation between the number of joint projects and investments and profits in this context we identify a second aspect of complementarity equilibrium investments in in house as well as in each joint project are increasing in the number of projects however we find that an increase in number of joint projects of all firms lowers collective profits suggesting the presence of excessive incentives for conducting research

information gathering through alliances abstract the effect of a firm s uncertainty regarding technological development on the formation of alliances is examined and it is shown that this uncertainty is positively related to the number of alliances however higher uncertainty also makes the firm less likely to ally with others if the collected information is redundant the higher the similarity between the technological regimes of potential alliance partners the lower the incentive to ally also direct ties are preferred to indirect ones if uncertainty is high since direct ties yield more accurate information than indirect ties

overview of the malawi energy situation and a pestle analysis for sustainable development of renewable energy this paper presents an overview of the malawi energy situation and the potential of renewable energy resources including solar wind biomass hydro and geothermal despite a range of efforts by local and international stakeholders to increase access to modern energy sources in the country 89 per cent of malawi s energy is still sourced from traditional biomass mainly fuel wood only 8 per cent of the population in malawi have access to electricity but installed capacity of electricity generation is lower than demand this leads to load shedding by the electricity supplier consequently electricity supply in malawi is unreliable and micro and macroeconomic activities are significantly affected solar non traditional biomass crop residues and forest residues not burnt on three stone fireplaces and biogas hydro wind and geothermal are potential energy resources that could enhance malawi s energy security however unreliable financing mechanisms for large scale energy projects shortage of trained human resource lack of coordination among local institutions unclear regulation enforcement and sometimes political governance impede sustainable delivery of energy projects the malawi energy policy targets and drivers are also discussed in the paper based on the prevailing energy situation a pestle analysis is provided in this paper outlining a novel thinking for addressing the political p economic e social s technological t legal l and environmental e challenges that constrain the development of renewable energy technologies in malawi

invisible energy policies a new agenda for energy demand reduction this article makes the case for a new and ambitious research and governance agenda for energy demand reduction it argues that existing demand side approaches focused on promoting technological efficiency and informed individual consumption are unlikely to be adequate to achieving future carbon emissions reduction goals it points out that very little attention has so far been paid to the impacts of non energy policies on energy demand and it submits that a much fuller integration of energy demand questions into policy is required it advances a general framework supported by illustrative examples for understanding the impacts of non energy policies on energy demand it reflects on why these connections have been so little explored and addressed within energy research and policy and it argues that for all their current invisibility there is nonetheless scope for increasing the visibility of and in effect mainstreaming energy demand reduction objectives within other policy areas researchers and policymakers we contend need to develop better understandings of how energy demand might be made governable and how non energy policies might be revised alone and in combination to help steer long term changes in energy demand

industrial energy substitution during the 1980s in the greek economy abstract factor substitution in greek manufacturing during the 1980s is examined using pooled data in static and dynamic translog expenditure share models inputs are capital labor electricity and non electrical energy liquid solid gas own price elasticities for capital and labor are inelastic but for electricity more elastic 0 90 results indicate substitutability among factors in the short run in the long run electricity and capital are complements as are labor and non electrical energy greek manufacturing is predicted to continue decreased consumption of liquid fuels to the year 2000 continuing the electrification begun in the 1970s

implied elasticities in some uk energy projections abstract this paper presents some estimates of price and income elasticities for the demand for total delivered energy to final users in the uk it compares these with the elasticities implicit in three energy projections for the uk and finds that the implicit elasticities in official projections are not obviously consistent with recent experience while the price elasticity implicit in an unofficial low energy projection is not obviously implausible these tentative but important conclusions are not in any way weakened by looking at other estimates

complementarity and external linkages the strategies of the large firms in biotechnology in biotechnology large firms enter into different kinds of linkages with universities and small medium sized research intensive firms we test the hypothesis that the strategies of external linkage of the large firms with other parties are complementary to one another we show that if any two strategies are complementary i e undertaking more of one strategy raises the marginal value of the other then they are positively correlated using data for a sample large us european and japanese chemical and pharmaceutical producers we find that the strategies above are positively correlated even after controlling for firm specific characteristics

the european renewable energy target for 2030 an impact assessment of the electricity sector abstract the european union set binding targets for the reduction of greenhouse gases ghg and the share of renewable energy re in final energy consumption by 2020 the european council agreed to continue with this strategy through to 2030 by setting a re target of 27 in addition to a ghg reduction target of 40 we provide a detailed sectoral impact assessment by analyzing the implications for the electricity sector in terms of economic costs and the regional distribution of investments and shares of electricity generated from renewable energy sources res e according to the impact analysis by the european commission the 27 re target corresponds to a res e share of 49 our model based sensitivity analysis on underlying technological and institutional assumptions shows that the cost effective res e share varies between 43 and 56 secondly we quantify the economic costs of these variants and those which would be incurred with higher shares the long term additional costs for higher res e shares would be less than 1 of total system costs the third aspect relates to the regional distribution of eu wide efforts for upscaling renewables we point out that delivering high res e shares in a cost effective manner involves considerably different efforts by the member states

strategizing by firms in the presence of markets for resources strategizing by firms from the resource based view is concerned with the process through which firms acquire a distinctive bundle of resources that is costly and time consuming for competitors to duplicate or imitate a central question facing any firm therefore is its strategy for accumulating the resources that underpin its production activities in this article the process of resource accumulation is discussed as one involving potentially both internal resource development and external resource acquisition from the perspective of the strategic issues involved in making a choice between these options emerging markets for technologies and know how through licensing and other forms of resource exchange have opened up new avenues through which firms may jostle for advantage the article is concerned with three major aspects of this process illustrating the discussion with cases from biotechnology and pharmaceuticals first the strategizing by firms around the internal development vs external sourcing issue is discussed as informed by the practices of leading firms and how these lend greater variety of strategic options for firms second the potential competitive advantages as well as disadvantages to be secured by firms through the process of external sourcing as compared with the well known potential advantages accruing to incumbents through internal development such as time compression diseconomies and causal ambiguity and third the criteria to be used by firms to strategically evaluate resources individually as contrasted with the strategic evaluation of the resource bundle or totality these criteria it is argued turn on the issues of marginal value contribution resource complementarities and synergies resource variety and transferability involving intellectual property issues successful firms it is argued expand their options through blending internal resource accumulation with external resource leverage thereby deepening their distinctive dynamic capabilities this approach extends the framework of the rbv enabling it to encompass resource driven schumpeterian competition and such aspects of industrial dynamics as specialization modularization and imitative challenge copyright 2003 oxford university press

economic growth and interfactor interfuel substitution in korea this paper investigates the impact of increases in oil consumption and changes in wage rates on the interfactor interfuel substitution in korea a two stage translog cost function is estimated to incorporate the feedback effect between the interfactor and interfuel substitution empirical results show that the substitutability complementarity relationships among factors and fuels exhibit substantially different patterns before and after 1989

complementarities of innovation activities an empirical analysis of the german manufacturing sector abstract innovation strategies in manufacturing often involve internal rd it is based on data from the german part of the community innovation survey cis 3 the results provide evidence for significant complementarities between internal r d and r d cooperation but cast doubt on the complementarity of internal and contracted r d since a productivity effect on firms patenting probability or sales with new products cannot be found

an investigation of co integration and causality between energy consumption and economic activity in taiwan applying hsiao a version of the granger causality method this paper examines the causality between energy and gnp and energy and employment by applying recently developed techniques of co integration and hsiao s version of the granger causality to taiwanese data for the 1955 1993 period the phillips perron tests reveal that the series with the exception of gnp are not stationary and therefore differencing is performed to secure stationarity the study finds causality running from gdp to energy consumption without feedback in taiwan it is also found that causality runs from gdp to energy but not vice versa

economic and environmental costs of replacing nuclear fission with solar and wind energy in sweden nuclear power is facing an uncertain future in sweden due to political directives that are seeking to phase out this energy source over coming decades here we examine the environmental and economic costs of hypothetical future renewable energy focused cases compared with the current nuclear and hydroelectricity centred mix in sweden we show that if wind and photovoltaics replace entire nuclear power while maintaining the current level of dispatchable backup capacity including hydroelectric power and peak gas power 154 gw of wind power will be required and will generate 427 1 twh compared with the actual demand of 143 7 twh to reliably meet demand each hour of the year as a consequence the annual spending on electricity systems will be five times higher than the status quo increasing dispatchable power increasing transmission capacities to other countries and generating electricity from combined heat and power plants even when there is no heat demand will together reduce the required capacities of wind and solar photovoltaic by half but it will double the greenhouse gas emissions during the combustion process in conclusion our economic and greenhouse gas emissions analyses demonstrate that replacing nuclear power with renewables will be neither economic nor environmentally friendly with regards to the climate

underlying causal factors of the european union energy intensity econometric evidence abstract the aim of the research is to determine the main factors that define the level of energy intensity in the countries of the european union the research was conducted by estimation of six baseline and six auxiliary regressions with and without time lags in form of one way fixed and random effects error component models on different unbalanced panel data samples covering the period 1995 2015 the obtained baseline regressions results generate three sets of findings the first set consists of extremely robust findings relating to the positive influence of gross fixed capital formation and industrial gross value added and negative effects of real per capita gross domestic product and oil products retail price these variables are statistically significant in all 36 baseline empirical models the second set of results consists of quite robust findings relating to insignificant influence of foreign direct investment and negative influence of coal price according to the results it cannot be confirm the hypothesis of energy saving technology transfer via foreign direct investments in european union member states the third set of results shows that the research has failed to generate any robust findings for economic openness import ratio urbanization and natural gas price which means that the effect of these determinants on energy intensity in european union member states is unspecified finally auxiliary regressions estimation results show that changes in the sectorial composition within the european union member states economies have not enhanced energy saving technological transfer via foreign direct investments

european energy policy a review this article presents the implemented policies of the european union in the broader field of energy and provides a picture of the union s strategy on energy related issues a brief historical background is provided covering the period from the beginning of the union s creation in 1951 when coal was considered as the heart of its economic growth up to 2012 policy development principles as well as the consultations that take place before the proposal of each option are also discussed implemented policies are classified into seven broad categories renewable energy energy efficiency and savings internal energy markets security of energy supply environmental protection nuclear energy and research and development for each category an introduction covering important milestones towards its development is followed by the presentation of the relevant policies and a description of their purpose

does public scientific research complement private investment in research and development in the pharmaceutical industry abstract this paper analyzes how pharmaceutical research and development r d investment responds to publicly supported biomedical research performed mainly at universities and nonprofit institutions new microlevel data on investment by the u s national institutes of health allow measures of public basic and clinical research in seven medical classes to be included in a distributed lag model explaining pharmaceutical r d investment using a panel of medical classes observed over 18 years the analysis found strong evidence that public basic and clinical research are complementary to pharmaceutical r d investment and thereby stimulate private industry investment however differences in the relevance and degree of scientific and market uncertainty between basic and clinical research lead to differences in the magnitude and timing of the pharmaceutical investment response

the demand for energy in greece assessing the effects of the community support framework 1994 1999 the paper estimates the demand for energy in greece in the tradable and non tradable sectors and for the three main types of energy namely oil electricity and solid fuel using the estimated demand functions forecasts of the demand for energy until the year 2010 are derived by incorporating the system of demand and energy price equations into a fully fledged annual macroeconometric model the model is subsequently used to forecast the demand for energy and the shares of various forms under alternative assumptions about the effects of the community support framework csf it is found that the demand for energy will be significantly affected by the presence of externalities in the implementation of csf that give rise to positive supply side effects and boost growth in the absence of supply side externalities total energy demand rises by 1 4 above the benchmark non csf scenario with growth inducing externalities total demand will increase at year 2010 by 6 0 above baseline

the strategic alliance of the biotechnology firm this article applies the relevant theories of firm organization and inter firm relationships in the high tech environment to explain the institutional reasons that firms choose between internal or external approaches particularly this study tries to understand to what extent and in what way strategic alliances have impacts on individual firms organizational structure financial structure and firms activities also it tries to find out what type of firms tend to benefit most from alliances and thus use more inter firm agreements the theoretical findings are that due to liquidity constraint and asymmetric information reasons young research intensive firms need to use more alliances to survive in the fast changing high technology industry the empirical analysis employs 3 year panel data and finds that the results are consistent with the theoretical predictions

stable coalition structures with open membership and asymmetric firms i study games of coalition formation with open membership where firms form associations in order to decrease their costs before competing on the market according to previous analyses only the grand coalition forms at the nash equilibrium of such games i show that this result hinges on the assumption of symmetric firms i therefore introduce asymmetric firms in a game where only two associations can form i demonstrate that there exists a coalition proof nash equilibrium coalition structure in this game and that when the equilibrium involves two associations all the members of an association have a higher taste for this association than all nonmembers do journal of economic literature classification numbers c70 c72 l13

heterogeneous technologies strategic groups and environmental efficiency technology gaps for european countries abstract this paper measures technology tg and environmental efficiency technology gaps eetgs in 25 european countries over two distinct periods 2002 and 2008 examining the possible effect of adopted environmental regulations and the kyoto protocol commitments on environmental efficiency technology gaps however the introduction of the metafrontier in our analysis puts into our discussion the role of heterogeneous technologies and its effect on the above mentioned measures employing a directional distance function we investigate whether there is an actual difference in terms of environmental efficiency and efficiency performance among european countries considering the technological frontiers under which they operate the construction of individual frontiers has been realized employing a large number of variables that are highly correlated with countries learning and absorbing capacity new technological knowledge and using economic theory and classical frontier discrimination like developed vs developing north vs south and participation in the eurozone or not the overall results indicate a crucial role of heterogeneous technologies for technology gaps in both periods moreover a significant decrease for both measures although in different percent has been recorded emphasizing the key role of knowledge spillovers

energy consumption and economic growth a causality analysis for greece abstract this paper investigates the causal relationship between aggregated and disaggregated levels of energy consumption and economic growth for greece for the period 1960 2006 through the application of a later development in the methodology of time series proposed by toda and yamamoto 1995 at aggregated levels of energy consumption empirical findings suggest the presence of a uni directional causal relationship running from total energy consumption to real gdp at disaggregated levels empirical evidence suggests that there is a bi directional causal relationship between industrial and residential energy consumption to real gdp but this is not the case for the transport energy consumption with causal relationship being identified in neither direction the importance of these findings lies on their policy implications and their adoption on structural policies affecting energy consumption in greece suggesting that in order to address energy import dependence and environmental concerns without hindering economic growth emphasis should be put on the demand side and energy efficiency improvements

energy models for demand forecasting a review abstract energy is vital for sustainable development of any nation be it social economic or environment in the past decade energy consumption has increased exponentially globally energy management is crucial for the future economic prosperity and environmental security energy is linked to industrial production agricultural output health access to water population education quality of life etc energy demand management is required for proper allocation of the available resources during the last decade several new techniques are being used for energy demand management to accurately predict the future energy needs in this paper an attempt is made to review the various energy demand forecasting models traditional methods such as time series regression econometric arima as well as soft computing techniques such as fuzzy logic genetic algorithm and neural networks are being extensively used for demand side management support vector regression ant colony and particle swarm optimization are new techniques being adopted for energy demand forecasting bottom up models such as markal and leap are also being used at the national and regional level for energy demand management

patents as indicators of corporate technological strength abstract quantitative indicators of the technological strengths of individual companies would be an important addition to the financial and economic data used in competitor assessments merger acquisition analyses investment decisions and corporate planning and management this paper examines the links between corporate patent and patent citation data and several other indicators of corporate performance changes in sales and profits research and development budgets scientific productivity and expert opinions of company technological strength the study covers 17 us pharmaceutical companies for which financial r d and expert opinion data were readily available for these pharmaceutical companies it was found that the patent data are an excellent indicator of overall corporate technological strength with 1 an overall correlation of 0 82 between expert opinion of pharmaceutical company technical strength and the number of us patents granted to the companies and 2 correlations in the general range of 0 6 to 0 9 between increases in company profits and sales and both patent citation frequency and concentration of company patents within a few patent classes

the energy efficient transformation of eu business enterprises adapting policies to contextual factors abstract business contexts differ in their ability to foster the energy efficient transformation eet of enterprises accordingly energy efficiency policies have to be adapted to different situations the present paper analyzes the relationships between the eet of european union eu business end users and three contextual factors i e high energy prices stringency of regulations and society s alertness toward environment conservation enterprises from 9 eu member states have been grouped according to country industry and size the final sample includes 256 enterprise classes and the model controls for the innovation propensity and energy intensity of each enterprise class our results show that regulatory stringency is the most impactful contextual factor while the environmental alertness of society does not have a significant effect concerns over energy costs have not been found to drive eet per se but more energy intensive enterprise classes are more likely to react to high energy prices we discuss the implications of our results for the eu governments that are currently monitoring and refining the transposition of the 2012 energy efficiency directive

elasticities science or fiction abstract apart from discrepancies in statistical data series the most frequent source of inconsistencies among elasticity estimates is the model specification and the interpretation of empirical results this paper investigates this issue and in particular highlights the misconception that elasticities can scientifically and uniquely be determined by econometric techniques however it is common knowledge that econometric methods constitute a very good tool for analysing the past thus the main message of this exercise is that in the absence of complete specification there are important trends in the elasticities themselves such trends are very crucial and need to be interpreted if elasticities are to be used for forecasting purposes

shifting policy priorities in eu china energy relations implications for chinese energy investments in europe shifting energy policy priorities both in china and the eu european union have transformed their bilateral relationship in order to assess the impact of domestic policy priorities on bilateral energy cooperation and climate policy this comparative study traces the evolution of eu and chinese approaches to energy policy and their relative emphasis on factors and frames such as availability efficiency affordability and environmental stewardship drawing on government documents and a data set of interviews with chinese policy makers experts and academics in 2015 2016 the article argues that while the eu started with a strong emphasis on environmental stewardship and moved towards a focus on affordability and availability china started with a strong emphasis on availability and has moved towards a greater emphasis on environmental stewardship this shift in frames on the chinese side and subsequent changes in subsidy structures and targets can partially explain the increase in investments in renewable energy technologies the article concludes that the chinese and eu perspectives have become more aligned over the past ten years coinciding with an increasing trend towards renewable energy in chinese energy investments in the eu for example in italy and the uk

interfuel substitution results from several sectors of the greek economy abstract the purpose of this paper is to study interfuel substitution in various sectors of the greek economy an econometric model utilizing the translog cost function is estimated for three major sectors of the economy agriculture industry disaggregated also into three branches and transport fuels are aggregated into three categories solid fuels liquid fuels and electricity the model is estimated using time series data over the period 1960 1980 the results indicate substitutability between liquid fuels and electricity mainly complementarity between liquid and solid fuels and substitutability between electricity and solid fuels

why do firms do basic research with their own money abstractthe question to be addressed is why do private firms perform basic research with their own money interest in this question derives from both analytical and utilitarian considerations there is empirical evidence in the united states which provides the main context for this paper supporting the view that basic research makes a significant contribution to the productivity growth of the economy 4 7 it is widely held that social returns from basic research are significant and higher than private returns and it is for this reason that most such activities continue to be financed by the taxpayer this also implies that measures aimed at increasing basic research by the private sector will be welfare improving in the united states the federal government in the years since the second world war has provided the vast majority of all funds devoted to basic research although the federal share has been declining in recent years and although that share is at its lowest level in about 20 years it still constitutes about two thirds of the total 10 this abstract was borrowed from another version of this item

energy consumption and economic growth assessing the evidence from greece abstract this paper attempts to shed light into the empirical relationship between energy consumption and economic growth for greece 1960 1996 employing the vector error correction model estimation the vector specification includes energy consumption real gdp and price developments the latter taken to represent a measure of economic efficiency the empirical evidence suggests that there is a long run relationship between the three variables supporting the endogeneity of energy consumption and real output these findings have important policy implications since the adoption of suitable structural policies aiming at improving economic efficiency can induce energy conservation without impeding economic growth

energy and economic growth in industrializing countries the case of greece abstract this paper investigates some aspects of the interrelated paths of economic growth and energy demand in the case of an industrializing economy through the use of numerous econometric models translog functions have helped establish that income and price elasticities of energy two critical parameters in the energy economy interaction exhibit falling trends with time the value share of the industrial sector is strongly associated with both energy demand and energy intensity any increase in the former will lead to amplified increases in the latter rendering the continuation of past trends in industrial expansion questionable under conditions of high energy costs substitution among capital labour and energy does take place though to a limited extent as indicated by the aggregate measure of energy non energy substitution elasticity all findings appear to suggest that energy policymaking in an industrializing country like greece will be of low effectiveness until certain structural changes in the economy are realized

cointegration and causality between electricity consumption and gdp empirical evidence from malawi abstract the granger causality gc and error correction ecm techniques were applied on 1970 1999 data for malawi to examine cointegration and causality between electricity consumption kwh and respectively overall gdp agricultural gdp agdp and non agricultural gdp ngdp cointegration was established between kwh and respectively gdp and ngdp but not with agdp the gc results detect bi directional causality between kwh and gdp suggesting that kwh and gdp are jointly determined but one way causality running from ngdp to kwh the ecm results detect causality running one way from gdp also from ngdp to kwh suggesting that a permanent rise in gdp may cause a permanent growth in electricity consumption

do urbanization and industrialization affect energy intensity in developing countries abstract against a backdrop of concerns about climate change peak oil and energy security issues reducing energy intensity is often advocated as a way to at least partially mitigate these impacts this study uses recently developed heterogeneous panel regression techniques like mean group estimators and common correlated effects estimators to model the impact that income urbanization and industrialization has on energy intensity for a panel of 76 developing countries in the long run a 1 increase in income reduces energy intensity by 0 45 to 0 35 long run industrialization elasticities are in the range 0 07 to 0 12 the impact of urbanization on energy intensity is mixed in specifications where the estimated coefficient on urbanization is statistically significant it is slightly larger than unity the implications of these results for energy policy are discussed

the european framework for energy and climate policies european energy and climate change policy rests on two main pillars the internal energy market iem and the climate change package ccp the iem aimed at third party access and unbundling neglecting the physical infrastructure and the basis for asset valuations and hence the harmonisation of network charges the commission plans to complete the iem by 2014 almost a quarter of a century after embarking on the policy yet even if all the iem directives are implemented the eu will remain far from a single competitive market the ccp was grounded on short term targets the 2020 20 20 programme on the assumption that fossil fuel prices would rise making renewables competitive and hence yielding a competitive advantage to the eu the euets was intended to lead the way to a global trading system and an international agreement at copenhagen the eu has reduced the production of carbon emissions but only as a result of de industrialisation and slow growth and at the expense of rising carbon consumption renewables have not led to green growth but rather to a further eroding of competitiveness the euets price has collapsed in order for the eu to put the iem and the ccp back on track both need to be radically reconsidered the iem requires a refocusing on physical infrastructure common accounting rules and an eu wide approach to capacity markets and renewables trading the ccp requires a refocusing on carbon consumption on limiting the dash for coal and on future rather than current renewables

is energy security a driver for economic growth evidence from a global sample abstract this study examines whether energy security contributes to economic growth for a global sample of 74 countries covering the period from 2002 to 2013 the benchmark model is built based on an extended version of the cobb douglas production function ten measures of energy security are employed to capture five aspects of energy security including availability accessibility acceptability affordability and develop ability besides the whole sample we also conduct the panel data analysis on subsamples of countries based on different income levels using panel corrected standard errors pcse and feasible generalized least squares fgls techniques that correct for heterogeneity and autocorrelation and produce robust standard errors the empirical results appear to be relatively robust to these two estimation techniques overall we find that energy security enhances economic growth for both the whole sample and subsamples of countries meanwhile energy insecurity measured by energy intensity and carbon intensity variables has a negative impact on economic growth the results vary across subsamples for several cases the findings imply that at the global level energy for economic development energy security and climate change mitigation should be pursued as integrated themes since there are linkages among these three agendas

a cost benefit analysis of the eu 20 20 2020 package the european commission did not publish a cost benefit analysis for its 2020 climate package this paper fills that gap comparing the marginal costs and benefits of greenhouse gas emission reduction the uncertainty about the marginal costs of climate change is large and skewed and estimates partly reflect ethical choices e g the discount rate the 2010 carbon price in the eu emissions trading system can readily be justified by a cost benefit analysis emission reduction is not expensive provided that policy is well designed a condition not met by planned eu policy it is probably twice as expensive as needed costing one in ten years of economic growth the eu targets for 2020 are unlikely to meet the benefit cost test for a standard discount rate 3 pure rate of time preference the benefit cost ratio is rather poor 1 30 so that benefits need to be very much higher or costs very much lower than typically assumed to justify the 2020 targets only a very low discount rate 0 prtp would justify the 20 emission reduction target for 2020

the electricity consumption and economic growth nexus evidence from greece abstract this paper attempts to cast light into the relationship between electricity consumption and economic growth in greece in a multivariate framework for this purpose we used cointegration techniques and the vector error correction model in order to capture short run and long run dynamics over the sample period 1970 2011 the empirical results reveal that in the long run electricity demand appears to be price inelastic and income elastic while in the short run the relevant elasticities are below unity we also argue that the causal relationship between electricity consumption and economic growth in greece is bi directional our results strengthen the notion that greece is an energy dependent country and well directed energy conservation policies could even boost economic growth furthermore the implementation of renewable energy sources should provide significant benefits ensuring sufficient security of supply in the greek energy system this evidence can provide a new basis for discussion on the appropriate design and implementation of environmental and energy policies for greece and other medium sized economies with similar characteristics

in search of complementarity in innovation strategy internal r d and external knowledge acquisition empirical research on complementarity between organizational design decisions has traditionally focused on the question of existence of complementarity in this paper we take a broader approach to the issue combining a productivity and an adoption approach while including a search for contextual variables in the firms strategy that affects complementarity analysis of contextual variables is not only interesting per se but also improves the productivity test for the existence of complementarity we use our empirical methodology to analyze complementarity between innovation activities internal research and development r d and external knowledge acquisition our results suggest that internal r d and external knowledge acquisition are complementary innovation activities but that the degree of complementarity is sensitive to other elements of the firms strategic environment we identify reliance on basic r dthe importance of universities and research centers as an information source for the innovation processas an important contextual variable affecting complementarity between internal and external innovation activities

governance and uncertainty the trade off between administrative control and commitment this study elaborates upon the motives for initiating equity based collaborations vs acquisition of another firm already having a desired technology we characterize both minority direct investments and joint ventures as options to defer either internal development or acquisition of a target firm in domains where learning about growth opportunities dominates investment activity this incremental mode of governance economizes on the cost of committing resources to a technology with an uncertain value using a sample of 402 transactions in the biotechnology industry we find strong support for the theoretical model the findings suggest that the cost of commitment in the face of technological uncertainty may offset the administrative benefits of hierarchical governance 1998 john wiley sons ltd

oil price shocks stock market economic activity and employment in greece abstract using a multivariate vector autoregression var approach this paper attempts to shed light into the dynamic relationship among oil prices real stock prices interest rates real economic activity and employment for greece the empirical evidence suggests that oil price changes affect real economic activity and employment oil prices are important in explaining stock price movements stock returns do not lead to changes in real activity and employment

effective incomplete contracts and milestones in market distant r d collaboration abstract r d outsourcing is often conducted during the early market distant stages of the innovation process however the main obstacle to this potentially efficient interfirm specialization is the high danger of moral hazard most organizational mechanisms fail to control that type of opportunism because of information asymmetries even ex post in the theory of incomplete contracts this problem is mitigated by assigning the control rights to the supplier to date empirical studies have mainly investigated the interfirm distribution of the control rights however we do not know yet which concrete control right is crucial with regard to supplier opportunism which is the decisive dependent variable our study addresses this research gap for the first time we extend the empirical focus from biotechnology and pharmaceutical firm alliances to a cross industry sample of 113 collaboration cases the results show the effectiveness of contracts that ex ante assign patent ownership rights to the supplier the findings are also relevant for management practice because the majority of practitioners do not use this contract type yet although there is no sign of an effective alternative

sensitivity of energy system investments to policy regulation changes too many too fast abstract in this paper we argue that the interaction of energy policy regulations in the european electricity sector may be described by the slow fast class of dynamical systems such systems may exhibit drastic changes in their dynamics known as bifurcations one important being the so called blue sky catastrophe once reaching such a state the slow system becomes unresponsive to the changes in the fast system for the energy policy nexus this translates into the energy system becoming unresponsive to policy interventions leading to a freeze in the system dynamics application of this result allows us to argue that caution is needed when updating economic policies to achieve a faster transition towards a low carbon energy supply structure to avoid this risk the policy design should be aimed at long term incentive structures with less frequent but more consistent interventions

capitalism as an engine of progress economists from marx to schumpeter have touted capitalism as an engine of technical progress but what kind of an engine is it what are its key components how does it work

electricity consumption and economic growth in india abstract this paper tries to examine the granger causality between electricity consumption per capita and gross domestic product gdp per capita for india using annual data covering the period 1950 51 to 1996 97 phillips perron tests reveal that both the series after logarithmic transformation are non stationary and individually integrated of order one this study finds the absence of long run equilibrium relationship among the variables but there exists unidirectional granger causality running from economic growth to electricity consumption without any feedback effect so electricity conservation policies can be initiated without deteriorating economic side effects

an aggregate model for energy costs national product interdependence abstract a small model is constructed which describes energy economy interactions on an aggregate level the model based on a neo classical approach estimates the impact on net national product and energy demand of changes in the cost of domestic and imported energy if tax and tariff rates as percentages of total price are kept constant a parametric analysis is carried out to investigate the role of structural parameters such as the price and income elasticities among others a key parameter of primary importance in the energy economy interaction is revealed to be the cost to output ratio of the energy sector through this parameter we are able to analyse the interdependence of the tariff rates the relative cost of imported to domestic energy and the energy import share and thereafter assess their combined effect on the energy economy interaction

firms motivations for cooperative r d an empirical analysis of spanish firms abstract the aim of this paper is to analyze the motives that have caused industrial firms to cooperate in r d there are many theoretical works devoted to the theme but few empirical studies have been carried out with large samples to analyze the factors which determine why firms cooperate in r d we first review the reasons offered by the literature to explain technological cooperation with this allowing us to determine the conceptual framework and to propose some hypotheses we test these hypotheses with a sample of 1652 spanish firms that have carried out r d activities the results obtained suggest that firms motivations for cooperative r d are the complexity of technology and the fact that innovation is costly and uncertain we find that in order to undertake cooperative r d it is necessary to have certain internal capacities in this area with our results being supported by the theory of absorptive capacity however and by contrast with the results presented in other works questions related to market access and search for opportunities do not appear to exert an influence over cooperative r d besides the large sized firms resort more to cooperation and the reasons for cooperative r d differ as between large and small sized firms

the role of knowledge in r d efficiency past research has recognized that both demand and capability influence the allocation of r d resources scholars have had an easier time getting a grip on demand than on capability while it has been recognized that knowledge is an important part of capability to date formalization of knowledge and its role in r d activity has been unsatisfactory this paper models the role of knowledge in r d various sources of such knowledge are considered the model throws a different light on analyses that employ a knowledge capital stock and also illuminates the dual private and public nature of technological knowledge

energy security measurement a sustainable approach abstract the main objective of this paper is to define new energy security indicator with the long term sustainability and to test it in a sample of 28 european union countries for the period 1990 2012 as well as to determine the level of impact of six different indicators on energy security the previous methodologies for measuring of energy security have been mainly focused on security of supply while not taking into account environmental indicators and the social component the newly proposed indicator energy security index differs from the existing measuring methods precisely in a way that it includes environmental and social aspects energy security index recorded a decline in values in most countries in the period 1990 2000 in the period 2000 2008 the values became positive and after 2008 some countries reported again gradual deterioration the index value varies by year and the biggest positive changes were recorded in the case of the netherlands slovenia and spain the four economically strongest eu countries the united kingdom france germany and italy recorded significantly less fluctuations in energy security over 23 years compared to other countries the data for france and denmark show that an increased share of energy from nuclear and renewable sources can compensate even increased energy import dependence the assessment of impact of individual indicators on energy security index was conducted by using principal component analysis and showed that energy intensity gdp per capita and carbon intensity have the greatest impact the countries of the former eastern bloc are facing particular challenges of energy security which is primarily related to the rapid economic growth and at the same time a high degree of dependence on import of energy generating products in terms of energy security the most stable transition was reported in hungary and poland

technological cooperative agreements and firm s r d intensity a note on causality relations abstract in this paper we apply a recently proposed model of vector autoregression for panel data to analyse the granger causality relationship between a firm s intramural r d intensity and technological cooperative agreements the analysis relies on a sample composed of 95 major us european and japanese firms in the semiconductor data processing and telecommunications industries observed during the period 1980 1986 decisions on interfirm technological collaborations are shown to cause a la granger decisions on internal r d investments and vice versa we thus suggest that in contrast with the methodological approaches followed by previous empirical works firms decisions concerning both intramural innovative effort and technological cooperation are endogenous and have to be jointly studied through a simultaneous two equation structural model
