renewable and non renewable energy growth emissions linkages review of emerging trends with policy implications abstract this study is an extension of the previous studies which focused mainly on energy growth nexus but fails to consider the carbon emission implication of this relationship the methodology of the study permits a comprehensive and comparative analysis of existing studies on renewable and non renewable energy growth emission nexus in order to draw some implications for policy and research the survey revealed the extent of the spread of studies across issues time and geographical space countries and regions it also disclosed the range of methodological approaches adopted to analyse the issues over time and the frequency of their use it unravelled the varied findings across countries and regions given the diverse methods employed and specific features of the economies analysed arising from the literature survey this study highlights the existing gaps in the literature and new direction for policy and research the general policy implication of the findings of this study is that pollution effect of energy growth nexus should be taken into consideration in policy formulation for sustainable development further the design of regional and global policies should recognise the fact that energy growth emission linkages varied across countries even in the same region some new direction for research on renewable and non renewable energy growth emission linkages pointed out in this survey includes the following future research on energy growth nexus without considering the pollution impact may not contribute so much to the literature studies should investigate the substitution complementary effects of the energy varieties on growth emission nexus while new methodological contributions are imperative

coal overcapacity in china multiscale analysis and prediction gaining a quantitative understanding of the causes of coal overcapacity and accurately predicting it are important for both government agencies and coal enterprises following the decomposition reconstruction prediction concept a combined ensemble empirical mode decomposition least square support vector machine autoregressive integrated moving average eemd lssvm arima model is proposed for quantitatively analyzing and forecasting coal overcapacity in china the results show that the main causes of coal overcapacity in china include insufficient demand market failure and institutional distortion institutional distortion with an influence degree of 73 75 is the most fundamental and influential factor from 2017 to 2019 the scale of coal overcapacity in china will reach between 1 721and 1 819 billion tons suggesting that coal overcapacity will remain a serious problem the rate of coal overcapacity caused by insufficient demand will fluctuate slightly while coal overcapacity caused by market failure will trend downward but the impact of institutional distortion on coal overcapacity will be exacerbated a statistical analysis demonstrates that the eemd lssvm arima model significantly outperformed other widely developed baselines e g arima lssvm eemd arima and eemd lssvm

renewable energy non renewable energy and economic growth in brazil this study employs brazil s yearly statistics from 1980 to 2010 to explore the causal relationships between the real gdp and four types of energy consumption non hydroelectric renewable energy consumption nhrec total renewable energy consumption trec non renewable energy consumption nrec and the total primary energy consumption tec the cointegration test reveals a long run equilibrium among brazil s real gdp labour capital and each of the four types of consumption the development of the brazilian economy has close ties with capital formation and labour force the influence of nhrec trec on real output is positive and significant while the impacts by nrec tec are insignificant the results from the vector error correction models reveal a unidirectional causality from nhrec to economic growth a bidirectional causality between economic growth and trec and a unidirectional causality from economic growth to nrec or tec without feedback in the long run these findings suggest that brazil is an energy independent economy and that economic growth is crucial in providing the necessary resources for sustainable development expanding renewable energy would not only enhance brazil s economic growth and curb the deterioration of the environment but also create an opportunity for a leadership role in the international system and improve brazil s competition with more developed countries

semicollusion in the norwegian cement market abstract a model of semicollusion where firms collude on prices and compete on capacities is tailor made to the characteristics of the norwegian cement market and tested on this particular market for the period 1927 1982 the results indicate that the rapid increase in capacity and thereby in exports in the period 1956 1967 the late phase of the price cartel best can be explained by the market sharing agreement each firm overinvested in capacity to receive a large quota in the domestic market

responses of agricultural bioenergy sectors in brandenburg germany to climate economic and legal changes an application of holling s adaptive cycle abstract agricultural bioenergy production is subject to dynamics such as yield fluctuations volatile prices resource competition new regulation and policy innovation and climate change this raises questions to what extent bioenergy production is able to adapt to changes and overcome critical events these dynamics have important implications for effective policy development using a case study method which draws on various data sources we investigate in detail how agricultural bioenergy sectors in the german state of brandenburg adapted to diverse past events the case analysis rests on the adaptive cycle concept and the system properties potential connectedness and resilience as defined by holling and gunderson 2002a our case study concludes that brandenburg s biogas sector has a low potential and connectedness within the system and a low resilience against crop failures the biofuels sector displays similar properties in the short term in the medium term the potential could increase in both sectors the properties imply risks and opportunities for biogas production and the possibility to develop towards a stage with a higher potential and a higher connectedness but adaptive capacity is limited and there are certain barriers for the agricultural bioenergy sectors to overcome potentially critical states policy needs to be tailored accordingly

renewable and non renewable energy use economic growth nexus the case of mena net oil importing countries abstract this study examines the energy use economic growth nexus by disaggregating energy use into two types of energy renewable and non renewable energy use our sample consists of eleven mena net oil importing countries noics during the period 1980 2012 a multivariate panel framework was used to estimate the long run relationship and the panel granger causality tests was employed to assess the causality direction among variables the empirical results provide evidence for long term equilibrium relationship between real gross domestic product gdp renewable energy use non renewable energy use real gross fixed capital formation and labor force the results provide evidence also for positive and statistically significant elasticities moreover the empirical findings from panel error correction model confirm the existence of bidirectional causality between renewable energy use and economic growth and between non renewable energy use and economic growth results that support the feedback hypothesis moreover our empirical findings provide evidence for two way bidirectional causal association in both the short and long run between renewable and non renewable energy use which proves the substitutability and interdependence between these two types of energy sources the policies implications of these results are also proposed and discussed

on the causal dynamics between emissions nuclear energy renewable energy and economic growth this paper examines the causal relationship between co2 emissions nuclear energy consumption renewable energy consumption and economic growth for a group of 19 developed and developing countries for the period 1984 2007 using a panel error correction model the long run estimates indicate that there is a statistically significant negative association between nuclear energy consumption and emissions but a statistically significant positive relationship between emissions and renewable energy consumption the results from the panel granger causality tests suggest that in the short run nuclear energy consumption plays an important role in reducing co2 emissions whereas renewable energy consumption does not contribute to reductions in emissions this may be due to the lack of adequate storage technology to overcome intermittent supply problems as a result electricity producers have to rely on emission generating energy sources to meet peak load demand

a re examination of the relationship between electricity consumption and economic growth in malaysia abstract the purpose of this study is to re investigate the relationship between electricity consumption and economic growth in malaysia from 1972 1 to 2003 4 this study adopted the newly developed ecm based f test kanioura a turner p 2005 critical values for an f test for cointegration in the multivariate model applied economics 37 3 265 270 for cointegration to examine the presence of long run equilibrium relationship through the autoregressive distributed lag ardl model the empirical evidence suggests that electricity consumption and economic growth are not cointegrated in malaysia however the standard granger s test and mwald test suggest that electricity consumption and economic growth in malaysia granger causes each other this finding provides policymakers with a better understanding of electricity consumption and allows them to formulate electricity consumption policy to support the economic development and to enhance the productivity of capital labour and other factors of production for future economic growth in malaysia

clean energy non clean energy and economic growth in the mist countries abstract this paper explores the causal relationship between clean renewable nuclear and non clean energy consumption and economic growth in emerging economies of the mist mexico indonesia south korea and turkey countries the panel co integration tests reveal that there is a long term equilibrium relationship among gdp capital formation labor force renewable nuclear and fossil fuel energy consumption the panel causality results indicate that 1 there is a positive unidirectional short run causality from fossil fuel energy consumption to economic growth with a bidirectional long run causality 2 there is a unidirectional long run causality from renewable energy consumption to economic growth with positive bidirectional short run causality and a long run causality from renewable to fossil fuel energy consumption with negative short run feedback effects and 3 there is a bidirectional long run causality between nuclear energy consumption and economic growth and a long run causality from fossil fuel energy consumption to nuclear energy consumption with positive short run feedback effects these suggest that mist countries should be energy dependent economies and that energy conservation policies may depress their economic development however developing renewable and nuclear energy is a viable solution for addressing energy security and climate change issues and creating clean and fossil fuel energy partnerships could enhance a sustainable energy economy

excess capacity and collusion in this paper the authors analyze a restricted class of equilibria in the dynamic model of j p benoit and v krishna 1987 in which firms choose their scale of operation before engaging in a repeated game of price competition benoit and krishna established that all firms carry excess capacity in all collusive equilibria as the authors are interested in the relationship between excess capacity and collusion in price they examine equilibria in which firms tacitly collude in price but not in investment decisions copyright 1990 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

to commit or not to commit revisiting quantity vs price competition in a differentiated industry previous studies have shown that quantity commitment by all firms in an industry mitigates price competition this paper shows that when firms have a choice asymmetric outcomes can arise with some firms choosing to commit to a quantity and other firms choosing not to to study the commitment decision we analyze a multistage game within a duopoly of differentiated firms a la hotelling in the first stage of the game firms choose whether or not to commit to a quantity in the second stage each firm that chose to commit sets a quantity which represents an upper bound on how much it can sell to consumers in the third stage both firms set prices strategically regardless of whether or not they committed in the final stage demand is allocated as consumers maximize their utilities firm s that chose not to commit to a quantity in the first stage can fulfill any quantity that consumers demand at the equilibrium prices we find that if product differentiation is sufficiently low both firms choose to co

on the causal dynamics between hydroelectricity consumption and economic growth in latin america countries abstract the aim of this study is to examine the relationship between hydroelectricity consumption and economic growth in seven latin america countries including argentina brazil chile colombia ecuador peru and venezuela the analysis is conducted within a neoclassical model involving capital and labour force for the period of 1970 2012 we utilize a recently developed cointegration test to investigate the long run relationship in the variables having established that the variables are cointegrated the results indicate long run bidirectional causality between hydroelectricity consumption and economic growth in argentina and venezuela there is evidence for long run unidirectional causality from hydroelectricity consumption to economic growth in brazil chile colombia ecuador and peru the long run coefficients from the regression analyses suggest that hydroelectricity consumption positively affect the economies of these latin american countries however limited evidence of causality between the two variables is found in the short run the ensuing policy implications of the findings are discussed

renewable energy consumption and economic growth nexus evidence from a threshold model abstract the existing literature on renewable energy consumption and economic growth nexus produces mixed results as the effect of renewable energy consumption on economic growth can be either positive negative or not significant this paper examines the causal link between renewable energy use and economic growth by employing a threshold model using a 103 country sample in the 1995 to 2015 period we find that the relationship between renewable energy consumption and economic growth depends on the amount of renewable energy used our results demonstrate that the effect of renewable energy consumption on economic growth is positive and significant if and only if developing countries or non oecd countries surpass a certain threshold of renewable energy consumption however if developing countries use renewable energy below a given threshold level the effect of renewable energy consumption on economic growth is negative however we also find that renewable energy consumption has no significant effect on economic growth in developed countries and a positive and significant effect on economic growth in oecd countries the findings of this paper suggest that for developing countries to realize positive economic growth from their investment to renewable energy they need to surpass a certain threshold of renewable energy consumption

renewable and non renewable energy consumption growth nexus evidence from a panel error correction model abstract unlike previous renewable energy consumption growth studies this study examines the relationship between renewable and non renewable energy consumption and economic growth for 80 countries within a multivariate panel framework over the period 1990 2007 the pedroni 1999 2004 heterogeneous panel cointegration test show a long run equilibrium relationship between real gdp renewable energy consumption non renewable energy consumption real gross fixed capital formation and the labor force with the respective coefficient estimates positive and statistically significant there is little difference in the elasticity estimates with respect to renewable and non renewable energy consumption the results from the panel error correction model reveal bidirectional causality between renewable and non renewable energy consumption and economic growth in both the short and long run also there is bidirectional short run causality between renewable and non renewable energy consumption indicative of substitutability between the two energy sources

patterns of attention to renewable energy in the british farming press from 1980 to 2013 abstract the farming sector is a major actor in developing renewable energy providing sites feedstock and investment media coverage can both drive and reflect levels of interest in renewable energy and affect policy support and farmer decision making about deployment this paper presents a content analysis of attention to renewable energy in the british farming press from 1980 to 2013 identifying the topics which sparked sustained media interest cycles of increased attention to specific types of renewable energy are made evident through quantification of article frequencies and qualitative analysis of content the findings contribute to the explanation of the role of information in the diffusion of renewable energy wind energy and liquid biofuels have received the most attention with multiple attention cycles whereas photovoltaics and anaerobic digestion have received focused attention only in recent years policy changes particularly support measures emerge as the most important driver of media attention although public controversies particularly in relation to wind energy lead to longer periods of attention attention typically increases when opportunities in renewable energy emerge and then quickly shifts to a longer stage of focused attention in which opportunities problems and solutions are explored and advice is offered before attention declines the media thus clearly play a role in informing farmers about opportunities arising in relation to renewable energy technology and policy developments but are less helpful in providing on going and consistent information about recurrent and more complex problems thus the farming press appears likely to have the strongest impact on early adopters of renewable technologies but is unlikely to contribute to diffusion at later stages when potential adopters are less willing to bear uncertainties

collusive pricing with capacity constraints in the presence of demand uncertainty we explore the response of collusive prices to changing demand conditions when firms operate under capacity constraints in the presence of demand uncertainty we find support for the conventional view that periods of low demand lead through the emergence of excess capacity to a breakdown of collusive pricing we also find that the nature of price wars depends on the degree of excess capacity in the industry while small amounts of excess capacity can lead firms to engage in mild price wars characterized by uniform price reductions and market share stability more severe price wars characterized by price undercutting and market share instability can emerge if excess capacity is sufficiently great finally our results lend support to the view that market share instability is a symptom of ineffective collusion

the causal relationship between energy resources and economic growth in brazil abstract this study investigates the causal relationship between clean and non clean energy consumption and economic growth in brazil over the period of 1980 2009 clean energy consumption at aggregated level of total renewable energy consumption and disaggregated levels of hydroelectric new renewables and nuclear energy consumption are tested within a production function framework a cointegration test reveals a long term equilibrium relationship between real output capital labor and renewable and non renewable energy consumption at aggregated level and a long term equilibrium relationship between real output capital labor and hydroelectric new renewables nuclear and fossil fuel energy consumption at disaggregated level the capital labor and new renewables elasticities of real output are positive and statistically significant other energy consumption item s elasticities are insignificant the results from error correction model reveal the interdependencies between new renewables nuclear fossil fuel and total non renewable energy consumption and economic growth the unidirectional causality from hydroelectric total renewable consumption to economic growth the substitutability between new renewables and fossil fuel consumption and the substitutability between new renewables and nuclear energy consumption additionally nuclear and new renewables energy consumption responds to bring the system back to equilibrium overall aggregated analysis may obscure the relationship between different types of clean energy consumption and economic growth

the expansion of renewable energies and employment effects in germany the promotion of electricity produced from renewable energy is a high priority of the european union as well of its member states the german government wants to increase the share of renewable energies from about 5 to 12 by 2010 to attain this goal the german government has introduced compulsory compensation schemes for electricity produced from renewable energy fed into the public grid this paper examines the economic impact of this policy employing an econometric model particular emphasis was given to employment effects in general we distinguish two effects 1 an expansive effect resulting from additional investments and 2 a contractive effect resulting from an increase in the production cost of power the first effect will dominate during the first years and lead to an increase in employment of approximately 33 000 new jobs however the contractive effect will offset these gains and lead to a slightly negative employment balance by 2010

the role of feed in tariff in the curtailment of wind power in china abstract while china s wind power initiative has experienced rapid growth serious curtailment issues persist though some studies have investigated this matter we explain this phenomenon from the novel perspective of excess capacity we first set up a theoretical model to explore the mechanism behind excess investment and find that the sticky feed in tariff fit and declining costs of wind power generate high mark up for wind power investors leading to a higher probability of excessive investment the theoretical prediction is empirically tested with a probit and tobit model using provincial level data between 2009 and 2016 the estimation results show that a 0 1 yuan increase in the mark up leads to a 2 3 increase in the rate of curtailed wind power based on the estimation results we simulate several scenarios to assess quantitatively how an improved policy design could have alleviated the curtailment issue simply increasing the frequency of the fit rate adjustment while maintaining the same subsidy reduction level between 2009 and 2016 could have reduced the curtailed wind power by 23 to 27 billion kwh accounting for 15 17 of actual curtailed wind power if the policy were better designed to reflect the declining trend of wind power costs more accurately the curtailment rates could have been further reduced by 2 81 corresponding to a reduction in wasted wind energy of 43 billion kwh or 28 of actual curtailment although accepting curtailment for a certain period could help to accelerate renewable energy deployment our analysis shows that the fit policy design could have been improved to reduce welfare loss these findings can not only assist the chinese government in framing effective policies but also may be applied to other emerging technologies or industries that require subsidy support

the economics of changing course implications of adaptability and inertia for optimal climate policy this paper reviews evidence that energy technologies and systems adapt over time to accommodate external pressures that technical innovation and systemic change in the energy sector is largely induced by need and restrained by potentially large transitional costs a simple integrated model of optimal greenhouse gas abatement over time is presented in which the abatement cost depends on both fixed and transitional elements it is shown that the optimal current response and long run prospects differ radically between the classical economic case in which the cost of a given cutback in emissions is fixed exogenously and the adaptive case in which the response is ultimately adaptive but heavily constrained by inertia ie low fixed but high transitional cost if energy systems are indeed to a large degree adaptive the results demonstrate that as compared with the classical non adaptive case long run stabilization of atmospheric co2 may be optimal even with moderate damages from climate change greater near term abatement efforts are justified and the cost of a given delay in response may be several times higher neglect of the issue of induced technical change and other adaptive responses may invalidate the policy implications drawn from most integrated assessment models developed to date

renewable energy in turkey great potential low but increasing utilization and an empirical analysis on renewable energy growth nexus abstract concerns about the exhaustion of fossil energy sources energy security problems and increasing environmental problems have led policy makers to pay greater attention to renewable energy sources all over the world additionally high current account deficits stemming from energy import dependency make substitution of fossil energy with renewable energy a necessity for turkey although turkey has a great potential in terms of renewable energy it has not begun to utilize this great potential until recent years however turkey has many motives to utilize renewable energy further this paper aims to investigate whether renewable energy consumption raises gdp in turkey for this purpose the paper uses data spanning the period 1990 2015 and employs cointegration and causality tests which can present efficient output in small samples the findings indicate that gdp is not related to renewable energy consumption and there is no causality between gdp and renewable energy consumption in turkey in conclusion the paper argues that these findings may stem from the low share of renewable energy in total energy and turkey needs to utilize renewable energy sources further to i meet energy needs for economic activities ii mitigate environmental problems and iii reduce energy import dependency and current account imbalances

an investigation of renewable and non renewable energy consumption and economic growth nexus using industrial and residential energy consumption abstract our study shows that links between economic growth and energy consumption both expressed in per capita terms differed for renewables and non renewables for income panels over the period 1971 to 2011 renewables are mainly found to support the neutrality hypothesis only renewable totals in low and lower middle income llmi countries are found to drive economic growth the feedback growth and conservative hypotheses strongly feature with non renewables total and industrial our results are derived by linking different definitions of energy consumption with economic growth for 89 countries divided into llmi upper middle income umi and high income hi panels

nuclear energy consumption and economic growth in oecd countries cross sectionally dependent heterogeneous panel causality analysis the purpose of this study is to determine the direction causality between nuclear energy consumption and economic growth in oecd countries the empirical model that includes capital and labor force as the control variables is estimated for the panel of fourteen oecd countries during the period 1980 2007 apart from the previous studies in the nuclear energy consumption and economic growth relationship this study utilizes the novel panel causality approach which allows both cross sectional dependency and heterogeneity across countries the findings show that there is no causality between nuclear energy consumption and economic growth in eleven out of fourteen cases supporting the neutrality hypothesis as a sensitivity analysis we also conduct toda yamamoto time series causality method and find out that the results from the panel causality analysis are slightly different than those from the time series causality analysis thereby we can conclude that the choice of statistical tools in analyzing the nature of causality between nuclear energy consumption and economic growth may play a key role for policy implications

a panel study of nuclear energy consumption and economic growth abstract this study examines the relationship between nuclear energy consumption and economic growth for sixteen countries within a multivariate panel framework over the period 1980 2005 pedroni s 1999 2004 heterogeneous panel cointegration test reveals there is a long run equilibrium relationship between real gdp nuclear energy consumption real gross fixed capital formation and the labor force with the respective coefficients positive and statistically significant the results of the panel vector error correction model finds bidirectional causality between nuclear energy consumption and economic growth in the short run while unidirectional causality from nuclear energy consumption to economic growth in the long run thus the results provide support for the feedback hypothesis associated with the relationship between nuclear energy consumption and economic growth

oil prices nuclear energy consumption and economic growth new evidence using a heterogeneous panel analysis abstract this paper applies panel data analysis to examine the short run dynamics and long run equilibrium relationships among nuclear energy consumption oil prices oil consumption and economic growth for developed countries covering the period 1971 2006 the panel cointegration results show that in the long run oil prices have a positive impact on nuclear energy consumption suggesting the existence of the substitution relationship between nuclear energy and oil the long run elasticity of nuclear energy with respect to real income is approximately 0 89 and real income has a greater impact on nuclear energy than do oil prices in the long run furthermore the panel causality results find evidence of unidirectional causality running from oil prices and economic growth to nuclear energy consumption in the long run while there is no causality between nuclear energy consumption and economic growth in the short run

judo economics reconsidered capacity limitation entry and collusion abstract the capacity investment by a new firm into an established market is explored in a repeated price game if the entrant expects collusion to prevail upon entry it may not practice judo economics but instead choose to install enough capacity to serve the entire market this occurs when collusion involves optimal punishment paths if instead collusion is based upon the static nash equilibrium punishment and the incumbent has excess capacity and the entrant is at a cost disadvantage the entrant will strategically limit its capacity so as to restrain the incumbent s price response to entry

equilibrium vertical differentiation in a bertrand model with capacity precommitment both quality differentiation and capacity commitment have been shown to relax price competition however their joint influence on the outcome of price competition has not yet been assessed in this article we consider a three stage game in which firms choose quality then commit to capacity and finally compete in price when the cost of quality is negligible we show that firms do not differentiate their products in a subgame perfect equilibrium in other words capacity precommitment completely eliminates the incentive to differentiate by quality

cartel pricing dynamics in the presence of an antitrust authority cartel pricing is characterized when firms are concerned about creating suspicions that a cartel has formed balancing concerns about maintaining the stability of the cartel with those of avoiding detection the cartel may either i gradually raise price to its steady state level or ii gradually raise price and then have it decline to its steady state level antitrust laws may have a perverse effect as they make cartel stability easier and thus allow for higher cartel prices

the savings growth nexus for the malaysian economy a view through rolling sub samples the purpose of this study is to re investigate the savings growth nexus for the malaysian economy using bounds testing approach to cointegration and toda and yamamoto 1995 and dolado and lutkepohl 1996 tydl granger causality test this study covered the sample period from 1971 q1 to 2008 q4 the cointegration results suggest that the variables are moving together in the long run and the tydl granger causality results indicate that the relationship between savings and economic growth is bilateral in addition the rolling sub samples tydl granger causality test exhibited a relatively stable causal relationship running from savings to economic growth in malaysia particularly before the onset of asian financial crisis in 1997 1998

governance and renewable energy investment in mena countries how does trade matter abstract the middle east and north africa mena countries have recently developed renewable energy re markets however their rate of investment in renewable energy remains small compared to other regions in the world despite their relatively abundant endowments particularly in wind and solar while the literature identifies some barriers to investment in renewable energy we assume that the investment of mena countries could be impeded by specific governance factors furthermore we consider recent literature showing that trade openness reduces the negative effects of weak governance in this paper we empirically investigate the link between governance openness and renewable energy investment in the mena region using panel data for 15 mena countries over the period 1996 2013 our results prove that high institutional quality is associated with re investment in mena countries in addition this relationship seems to be conditional on the trade regime our results are robust to several measures of renewable energy investment and governance as well as to an alternative econometric set up

models of technology diffusion abstract the literature on new technology diffusion is vast and it spills over many conventional disciplinary boundaries this paper surveys the literature by focusing on alternative explanations of the dominant stylized fact that the usage of new technologies over time typically follows an s curve the most commonly found model which is used to account for this model is the so called epidemic model which builds on the premise that what limits the speed of usage is the lack of information available about the new technology how to use it and what it does the leading alternate model is often called the probit model which follows from the premise that different firms with different goals and abilities are likely to want to adopt the new technology at different times in this model diffusion occurs as firms of different types gradually adopt it there are actually many ways to generate an s curve and the third class of models which we examine are models of density dependence popularized by population ecologists in these models the twin forces of legitimation and competition help to establish new technologies and then ultimately limit their take up finally we look at models in which the initial choice between different variants of the new technology affect the subsequent diffusion speed of the chosen technology such models often rely on information cascades which drive herd like adoption behaviour when a particular variant is finally selected

an anatomy of cartel contracts we study cartel contracts using data on 18 contract clauses of 109 legal finnish manufacturing cartels one third of the clauses relate to raising profits the others deal with instability through incentive compatibility cartel organization or external threats cartels use three main approaches to raise profits price market allocation and specialization these appear to be substitutes choosing one has implications on how cartels deal with instability simplifying we find that large cartels agree on prices cartels in homogenous goods industries allocate markets and small cartels avoid competition through specialization

renewable energy policies and contradictions in causality a case of next 11 countries abstract numerous studies on the causal relationship between economic growth energy consumption and carbon dioxide co2 emissions have shown divergence in policy recommendations which arises mainly due to the choice of methodology and the period of study this inconclusiveness in policy prescriptions might turn out to be critical when the renewable energy policies of the developing nations are considered our study analyses the causal relationship between economic growth carbon emissions fossil fuel and renewable energy consumption in next 11 countries during the period of 1990 2016 along with conducting parametric and non parametric causality tests together introducing the geweke 1982 causality test in the literature of energy economics we attempt to establish a wholesome aspect of policy design by comparing and complementing results of different causality analysis and how the causality directions should comply with the context setting our empirical evidence confirms that robust renewable energy policy can be designed by complementing the various causality test results rather than focusing on one particular causality test

the determination of price and output quotas in a heterogeneous cartel applying a selection criterion that uses both subgame perfection and the nash bargaining solution this paper investigates the relationship between firms cost functions and collusive behavior it is found that the optimal collusive price exceeds the price that the low cost firm would set if it was a monopolist comparative statics reveal that the optimal collusive price is increasing in the low cost firm s unit cost but is decreasing in the high cost firm s unit cost when the cost differential between firms is sufficiently large copyright 1991 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the impact of renewable energy consumption to economic growth a replication and extension of abstract this study replicates and extends the results presented in a top cited article in this journal inglesi lotz 2016 which analyzes the impact of renewable energy consumption to economic growth for the oecd countries by applying the ordinary least squares with fixed effect estimator on the data from 1990 to 2010 by using the same data and methods this study first produces and compare empirical results with those reported in the original article then it applies a set of new econometric methods on the same data to address heterogeneity in renewable energy and economic growth across the analyzed group of countries the panel quantile regression estimation shows that the effect of renewable energy consumption on economic growth is positive for lower and low middle quantiles however its effect becomes negative for middle high middle and higher quantiles when renewable energy consumption is proxied by the absolute value furthermore a negative impact of renewable energy on economic growth is observed in almost all quantiles when it is proxied by the share of renewable energy consumption to total energy consumption these results greatly differ from those of the original study

tacit collusion in the presence of cyclical demand and endogenous capacity levels abstract we analyze tacit collusion in an industry characterized by cyclical demand and long run scale decisions firms face deterministic demand cycles and choose capacity levels prior to competing in prices our focus is on the nature of prices we find that two types of price wars may exist in one collusion can involve periods of mixed strategy price wars in the other consistent with the rotemberg and saloner 1986 definition of price wars we show that collusive prices can also become counter cyclical we also establish pricing patterns with respect to the relative prices in booms and recessions if the marginal cost of capacity is high enough holding current demand constant prices in the boom are generally lower than the prices in the recession this reverses the results of haltiwanger and harrington 1991 in contrast if the marginal cost of capacity is low enough then prices in the boom are generally higher than the prices in the recession for costs in an intermediate range numerical examples are calculated to show specific pricing patterns

a literature survey on energy growth nexus abstract this paper provides a survey of the recent progress in the literature of energy consumption economic growth and electricity consumption economic growth causality nexus the survey highlights that most empirical studies focus on either testing the role of energy electricity in stimulating economic growth or examining the direction of causality between these two variables although the positive role of energy on growth has become a stylized fact there are some methodological reservations about the results from these empirical studies a general observation from these studies is that the literature produced conflicting results and there is no consensus neither on the existence nor on the direction of causality between energy consumption electricity consumption and economic growth as a policy implication to avoid from conflicting and unreliable results the authors may use the autoregressive distributed lags bounds test two regime threshold co integration models panel data approach and multivariate models including new variables such as real gross fixed capital formation labor force carbon dioxide emissions population exchange rates interest rates etc thus the authors should focus more on the new approaches and perspectives rather than by employing usual methods based on a set of common variables for different countries and different intervals of time

consumer choice and cournot behavior in capacity constrained duopoly competition in a two stage model of duopolistic capacity choice and subsequent price competition consumer switching costs can deter some consumers from seeking service at a low price firm that lacks sufficient capacity to serve the entire market in this setting firms residual demand functions are aggregatedfrom thefirm selection decisions of individual consumers based on firms prices and their induced degrees of service reliability if consumers are approximately risk neutral with respect to service reliability then capacity constrained duopoly competition has a unique subgame perfect equilibrium in which firms choose cournot capacities and prices the equilibrium robustness of cournot behavior extends to duopoly markets in which consumer switching costs are induced by subscription pricing
