the effect of decision order on purchase quantity decisions abstract consumers often resolve trade offs in a particular order for example when making flavor and size decisions consumers might first decide which flavors to choose and then decide which sizes of those flavors to choose this research examines the effect of decision order on purchase quantity decisions the authors build on prior work on decision difficulty and conflict to show that consumers choose more overall and more variety when they consider a less replaceable attribute in an earlier rather than a later stage in the purchase decision for example consumers choose a greater quantity when flavor or brand decisions precede rather than follow size decisions the authors find that the degree of attribute replaceability also moderates the effect of decision order on quantity chosen furthermore marketers can influence the amount chosen by altering the organization of the shelf display finally the authors find that when consumers explicitly consider the possibility of deferring their dec

assessing income population and technology impacts on co2 emissions in canada where s the ekc abstract this study investigates the macroeconomic forces underlying carbon dioxide co2 emissions from fossil fuel use in canada in keeping with the relevant literature on environmental degradation three forces are expected to influence co2 emissions gross domestic product per capita gdp capita population and technological change while previous work has employed reduced form models that allow for non linear relationships between co2 and gdp capita it has been common practice to assume linear relationships between co2 and the latter two variables this study tests a more flexible model using a five region panel data set in canada over the period 1970 2000 findings indicate that gdp capita is unrelated to co2 that an inverted u shaped relationship exists with population and that a u shaped relationship exists with technology thus technological and population changes are supported over the commonly hypothesized environmental kuznets curve an inverted u shaped relationship between gdp capita and environmental degradation for affecting co2 emissions from fossil fuel use in canada

co2 emissions energy consumption economic growth and financial development in gcc countries dynamic simultaneous equation models abstract this study investigates the dynamic causal relationships among carbon emissions financial development economic growth and energy consumption for gulf cooperation council gcc countries from 1980 through 2011 annual time series data and an autoregressive distributed lag ardl model are used the main contribution of this paper is that it has investigated the causes of carbon emissions by taking into account the role of financial development and economic growth in gcc countries the results suggest long run and causal relationships among carbon emissions financial development gross domestic product gdp and energy use in all gcc countries except united arab emirates uae moreover there is long run unidirectional causality running from carbon emissions to energy use in the case of saudi arabia uae and qatar furthermore a one way causal relationship from financial development to carbon emissions in the context of uae oman and kuwait is found the evidence suggests that financial systems should take into account environmental aspects in their current operations in these countries the results of this study may be of great importance for policy and decision makers in developing energy policies for gcc countries that contribute to curbing carbon emissions while preserving economic growth

the effect of time pressure on consumer choice deferral this article investigates the effect of time pressure on choice deferrai recent research suggests that the likelihood of deferral is contingent on the ease of making the selection decision which option to choose as well as the overali attractiveness of the selected alternative we focus on how time pressure systematically impacts choice deferral by increasing the use of noncompensato ry decision rules in the selection decision and by increasing the relative emphasis placed on the unique features in the deferral decision whether to choose consistent with the hypotheses we find over a series of five studies that time pressure 1 decreases choice deferral when choice involves high conflict but not when conflict is low 2 reduces the impact of shared features on choice deferral and 3 decreases choice deferral for sets with common bad and unique good features approach approach conflict but not for sets with common good and unique bad features avoidance avoidance conflict we further show that greater attention to the unique features is not a general property of decision making under time pressure but rather a consequence of the primacy of the selection decision over the deferral decision consistent with this premise time pressure did not decrease the relative attention paid to common features when the task was described as purely a deferral decision the theoretical and practical implications of the findings are discussed

economic growth and pollutant emissions in tunisia an empirical analysis of the environmental kuznets curve abstract this paper investigates the relationship between economic growth and pollutant emissions for a small and open developing country tunisia during the period 1961 2004 the investigation is made on the basis of the environmental kuznets curve hypothesis using time series data and cointegration analysis carbon dioxide co 2 and sulfur dioxide so 2 are used as the environmental indicators and gdp as the economic indicator our results show that there is a long run cointegrating relationship between the per capita emissions of two pollutants and the per capita gdp an inverted u relationship between so 2 emissions and gdp has been found with income turning point approximately equals to 1200 constant 2000 prices or to 3700 in ppp constant 2000 prices however a monotonically increasing relationship with gdp is found more appropriate for co 2 emissions furthermore the causality results show that the relationship between income and pollution in tunisia is one of unidirectional causality with income causing environmental changes and not vice versa both in the short run and long run this implies that an emission reduction policies and more investment in pollution abatement expense will not hurt economic growth it could be a feasible policy tool for tunisia to achieve its sustainable growth in the long run

bounds testing approach to analyzing the environment kuznets curve hypothesis with structural beaks the role of biomass energy consumption in the united states abstract this paper re examines the specification of the environmental kuznets curve ekc for the us economy by accounting for the presence of a major renewable energy source and trade openness over the period 1960 2016 biomass energy consumption and trade openness as well as oil prices are considered as additional determinants of economic growth and consequentially of co 2 emissions the bounds testing approach to cointegration is used to examine the long run relationship between the variables in the presence of structural breaks the causal relationship between the variables is investigated by applying the vecm granger causality test and accommodating structural breaks the results confirm the presence of cointegration between the variables moreover the relationship between economic growth and co 2 emissions is not only inverted u shaped but also n shaped in the presence of structural breaks and biomass biomass energy consumption lowers co 2 emissions exports imports and trade openness are also environment friendly the causality analysis underscores a feedback effect between biomass energy consumption and co 2 emissions economic growth still granger causes co 2 emissions in this new setup

the environmental kuznets curve and the role of coal consumption in india cointegration and causality analysis in an open economy abstract this study investigates the dynamic relationship between coal consumption economic growth trade openness and co2 emissions in case of india in doing so narayan and popp journal of applied statistics 2010 37 1425 1438 structural break unit test is applied to test the order of integration of the variables long run relationship between the variables is tested by applying the ardl bounds testing approach to cointegration developed by pesaran et al journal of applied econometrics 2001 16 289 326 the results confirm the existence of cointegration for long run between coal consumption economic growth trade openness and co2 emissions our empirical exercise indicates the presence of environmental kuznets curve ekc in long run as well as in short run coal consumption as well as trade openness contributes to co2 emissions the causality analysis reports the feedback hypothesis between economic growth and co2 emissions and same inference is drawn between coal consumption and co2 emissions moreover trade openness granger causes economic growth coal consumption and co2 emissions

the impacts of transport energy consumption foreign direct investment and income on co2 emissions in asean 5 economies abstract in this study we incorporate new variables and assess the impact of transportation sector s energy consumption and foreign direct investment on co2 emissions for asean 5 economies using the cointegration and granger causality methods this study also attempts to validate the environmental kuznets curve ekc hypothesis our results reveal that the co2 emissions and their determinants are co integrated only in indonesia malaysia and thailand the long run elasticity estimation suggests that income and transport energy consumption significantly influence co2 emissions whereas fdi is not significant economic growth plays a greater role in contributing to co2 emission in asean 5 nonetheless we find that the inverted u shape ekc hypothesis is not applicable to the asean 5 economies especially in indonesia malaysia and thailand in the long run the bi directional causality between economic growth and co2 emissions is detected in indonesia and thailand while we find unidirectional causality running from gdp to co2 emissions in malaysia we also observe bi directional causality between transport energy consumption fdi and co2 emissions in thailand and malaysia as an immediate policy option controlling energy consumption in transportation sector may result in a significant reduction in co2 emissions however this may slow the process of economic growth in malaysia and indonesia alternatively we suggest policymakers to place more emphasis on energy efficient transportation system and policies to minimise fossil fuel consumption thus the quality of environment can be improved with less deleterious impact on economic growth

the renewable energy growth and environmental kuznets curve in turkey an ardl approach abstract this study examines the potential of renewable energy sources in reducing the impact of ghg emissions in turkey using autoregressive distributed lag ardl approach the relationship between co 2 emissions electricity generated using renewables and gdp in turkey has been investigated during 1961 2010 moreover the validity of environmental kuznets curve ekc hypothesis has been tested model results show that the coefficient of electricity production from renewable sources hydro power excluded with respect to co 2 emissions is negative and significant in the long run although this effect is positive and statistically significant in the short run since the ecm term is 0 82 it becomes negative around 1 year this means that renewable electricity production will contribute to environmental enhancement with a one year lag our results also suggest a u shaped ekc relationship between per capita ghgs and income estimations from a long run regression show that although the peak point of gdp per capita has been calculated to be 9920 us dollars this turning point was outside of the observed sample period therefore ghg emissions start to decrease with an increase in per capita gdp in the following years model research implies the potential and the importance of renewable energy sources in controlling of emissions in turkey

technological innovation and real investment booms and busts abstract we investigate why new high risk technologies can attract excessive and often unprofitable investment we develop an equilibrium model in which rational risk averse agents overinvest in a risky technology possibly to the point that its expected return is negative overinvestment results from relative wealth concerns which arise endogenously from the imperfect tradability of future endowments competition over future consumption leads to an indirect utility for wealth with keeping up with the joneses properties that can induce herding because overinvestment increases with the risk of the technology our model can explain why new risky technological innovations may promote investment bubbles

energy consumption real income and temporal causality results from a multi country study based on cointegration and error correction modelling techniques abstract unlike previous studies on the causal relationship between energy consumption and economic growth this paper illustrates how the finding of cointegration i e long term equilibrium relationship between these variables may be used in testing granger causality based on the most recent johansen s multivariate cointegration tests preceded by various unit root or non stationarity tests we test for cointegration between total energy consumption and real income of six asian economies india pakistan malaysia singapore indonesia and the philippines non rejection of cointegration between variables rules out granger non causality and imples at least one way of granger causality either unidirectional or bidirectionial secondly by using a dynamic vector error correction model we then analyse the direction of granger causation and hence the within sample granger exogeneity or endogeneity of each of the variables thirdly the relative strength of the causality is gauged through the dynamic variance decomposition technique by decomposing the total impact of an unanticipated shock to each of the variables beyond the sample period into proportions attributable to shocks in the other variables including its own in the bivariate system results based on these tools of methodology indicate that while all pair wise relationships shared common univariate integrational properties only relationships for three countries india pakistan and indonesia were cointegrated for these countries temporal causality results were mixed with unidirectional causality from energy to income for india exactly the reverse for indonesia and mutual causality for pakistan the vdcs were not inconsistent with these results and provided us with an additional insight as to the relatively more dominant direction of causation in pakistan simple bivariate vector autoregressive models for the three non cointegrated systems did not indicate any direction of causality significantly in either direction

carbon dioxide emissions and economic growth panel data evidence from developing countries in this paper we test the environment kuznet s curve ekc hypothesis for 43 developing countries we suggest examining the ekc hypothesis based on the short and long run income elasticities that is if the long run income elasticity is smaller than the short run income elasticity then it is evident that a country has reduced carbon dioxide emissions as its income has increased our empirical analysis based on individual countries suggests that jordan iraq kuwait yemen qatar the uae argentina mexico venezuela algeria kenya nigeria congo ghana and south africa approximately 35 per cent of the sample carbon dioxide emissions have fallen over the long run that is as these economies have grown emissions have fallen since the long run income elasticity is smaller than the short run elasticity we also examine the ekc hypothesis for panels of countries constructed on the basis of regional location using the panel cointegration and the panel long run estimation techniques we find that only for the middle eastern and south asian panels the income elasticity in the long run is smaller than the short run implying that carbon dioxide emission has fallen with a rise in income

co2 emissions renewable energy and the environmental kuznets curve a panel cointegration approach abstract this study combines a panel cointegration analysis with a set of robustness tests to assess the short and long run impacts of renewable energy on co2 emissions as well as the kuznets environmental curve hypothesis for 25 selected african countries over the period 1980 2012 the results provide no evidence of a total validation of ekc predictions however co2 emissions are found to increase with income per capita the overall estimations strongly reveal that renewable energy with a negative effect on co2 emissions coupled with an increasing long run effect remains an efficient substitute for the conventional fossil fuelled energy nonetheless the impact of renewable energy is outweighed by primary energy consumption in both the short and long run entailing more global synergy for outpacing the environmental challenges

co2 emission and economic growth in algeria abstract algeria is one of the most important co 2 emitters among developing countries and the third among african countries it pledged to curb carbon emissions by at least 7 by 2030 however complying with this target may be a difficult task without compromising economic growth the aim of this paper is to analyze the relationship between co 2 emissions and economic growth in algeria taking into account energy use electricity consumption exports and imports the validity of the ekc hypothesis throughout the period from 1970 to 2010 is tested by using the autoregressive distributed lag model extended to introduce the break points results confirm the ekc for algeria nevertheless the turning point is reached for a very high gdp per capita value indicating that economic growth in algeria will continue to increase emissions results also indicate that an increase in energy use and electricity consumption increase co 2 emissions and that exports and imports affect them negatively and positively respectively therefore it is necessary to promote renewable energies and energy efficiency policies regulatory reforms are needed to facilitate foreign investments with which to carry out these policies likewise it may be appropriate to decrease subsides in energy prices to encourage energy efficiency

does financial development increase energy consumption the role of industrialization and urbanization in tunisia this paper assesses the relationship among energy consumption financial development economic growth industrialization and urbanization in tunisia from 1971 to 2008 the autoregressive distributed lag bounds testing approach to cointegration and granger causality tests is employed for the analysis the result confirms the existence of long run relationship among energy consumption economic growth financial development industrialization and urbanization in tunisia long run bidirectional causalities are found between financial development and energy consumption financial development and industrialization and industrialization and energy consumption hence sound and developed financial system that can attract investors boost the stock market and improve the efficiency of economic activities should be encouraged in the country nevertheless promoting industrialization and urbanization can never be left out from the process of development we add light to policy makers with the role of financial development industrialization and urbanization in the process of economic development

testing the kuznets curve hypothesis for qatar a comparison between carbon dioxide and ecological footprint abstract this paper explores the validity of the environmental kuznets curve ekc using two different environment indicators the carbon dioxide emissions co2 and the ecological footprint ef in qatar over the 1980 2011 period to this end we investigate the impact of real gross domestic product rgdp the square of rgdp the energy use the financial development and the trade openness on the co2 emissions and the ef we employ the autoregressive distributed lag ardl model with the presence of unknown structural breaks in order to study short run and long run elasticity between the variables the findings infer that there is a long run relationship among the selected variables with a shift in the cointegration vector in 1991 and 2000 the empirical result indicates that the inverted u shaped hypothesis is not valid in qatar when we use the co2 emissions whereas the inverted u shaped held when using the ef furthermore the error correction results confirm that the convergence towards the long run equilibrium will mostly occur within one year after a short run shock generally the findings suggest that qatar should invest more in efficient energy and continue sustained its growth moreover more efforts are needed for diversification particularly in technology intensive and environment friendly industries to improve environmental quality

electricity consumption employment and real income in australia evidence from multivariate granger causality tests this paper examines the relationship between electricity consumption employment and real income in australia within a cointegration and causality framework we find that electricity consumption employment and real income are cointegrated and that in the long run employment and real income granger cause electricity consumption while in the short run there is weak unidirectional granger causality running from income to electricity consumption and from income to employment

the effects of environmental regulation and technical progress on co2 kuznets curve an evidence from china based on environmental kuznets curve theory a panel data model which takes environmental regulation and technical progress as its moderating factors was developed to analyse the institutional and technical factors that affect the path of low carbon economic development the results indicated that there was a co2 emission kuznets curve seen in china environmental regulation had a significant moderating effect on the curve and the inflection of co2 emissions could come substantially earlier under stricter environmental regulation meanwhile the impact of technical progress on the low carbon economic development path had a longer hysteresis effect but restrained co2 emission during its increasing stage and accelerated its downward trend during the decreasing stage which was conducive to emission reduction strict environmental regulation could force the high carbon emitting industries to transfer from the eastern regions to the central or the western regions of china which would make the co2 kuznets curve higher in its increasing stage and lower in its decreasing stage than that under looser regulation furthermore energy efficiency energy structure and industrial structure exerted a significant direct impact on co2 emissions we should consider the above factors as essential in the quest for low carbon economic development

environmental degradation economic growth and energy consumption evidence of the environmental kuznets curve in malaysia this paper tests for the short and long run relationship between economic growth carbon dioxide co2 emissions and energy consumption using the environmental kuznets curve ekc by employing both the aggregated and disaggregated energy consumption data in malaysia for the period 1980 2009 the autoregressive distributed lag ardl methodology and johansen juselius maximum likelihood approach were used to test the cointegration relationship and the granger causality test based on the vector error correction model vecm to test for causality the study does not support an inverted u shaped relationship ekc when aggregated energy consumption data was used when data was disaggregated based on different energy sources such as oil coal gas and electricity the study does show evidences of the ekc hypothesis the long run granger causality test shows that there is bi directional causality between economic growth and co2 emissions with coal gas electricity and oil consumption this suggests that decreasing energy consumption such as coal gas electricity and oil appears to be an effective way to control co2 emissions but simultaneously will hinder economic growth thus suitable policies related to the efficient consumption of energy resources and consumption of renewable sources are required

defensive marketing strategies this paper analyzes how a firm should adjust its marketing expenditures and its price to defend its position in an existing market from attack by a competitive new product our focus is to provide usable managerial recommendations on the strategy of response in particular we show that if products can be represented by their position in a multiattribute space consumers are heterogeneous and maximize utility and awareness advertising and distribution can be summarized by response functions then for the profit maximizing firm it is optimal to decrease awareness advertising it is optimal to decrease the distribution budget unless the new product can be kept out of the market a price increase may be optimal and even under the optimal strategy profits decrease as a result of the competitive new product furthermore if the consumer tastes are uniformly distributed across the spectrum a price decrease increases defensive profits it is optimal at the margin to improve product quality in the direction of the defending product s strength and it is optimal at the margin to reposition by advertising in the same direction in addition we provide practical procedures to estimate 1 the distribution of consumer tastes and 2 the position of the new product in perceptual space from sales data and knowledge of the percent of consumers who are aware of the new product and find it available competitive diagnostics such as the angle of attack are introduced to help the defending manager this article was originally published in marketing science volume 2 issue 4 pages 319 360 in 1983

investigation of the causal relationships between combustible renewables and waste consumption and co2 emissions in the case of tunisian maritime and rail transport abstract this study investigates the dynamic causal links between carbon dioxide co 2 emissions real gross domestic product gdp combustible renewables and waste consumption and maritime and rail transport in tunisia spanning the period 1980 2011 the autoregressive distributed lag ardl approach and granger causality tests are employed to examine the short and long run relationships between variables the empirical results suggest a bidirectional short run causality between co 2 emissions and maritime transport and a unidirectional causality running from real gdp combustible renewables and waste consumption rail transport to co 2 emissions the long run estimates reveal that real gdp contributes to the decrease of co 2 emissions while combustible renewables and waste consumption and maritime and rail transport have a positive impact on emissions our policy recommendation is that tunisia should use more combustible renewables and waste energy and increase the number of passenger s rail and maritime transport in order to motivate economic activities however the level of renewables energy required to reduce co 2 emissions caused by transport sector is still very weak

modeling loss aversion and reference dependence effects on brand choice based upon a recently developed multiattribute generalization of prospect theory s value function tversky and kahneman 1991 we argue that consumer choice is influenced by the position of brands relative to multiattribute reference points and that consumers weigh losses from a reference point more than equivalent sized gains loss aversion we sketch implications of this model for understanding brand choice we develop a multinomial logit formulation of a reference dependent choice model calibrating it using scanner data in addition to providing better fit in both estimation and forecast periods than a standard multinomial logit model the model s coefficients demonstrate significant loss aversion as hypothesized we also discuss the implications of a reference dependent view of consumer choice for modeling brand choice demonstrate that loss aversion can account for asymmetric responses to changes in product characteristics and examine other implications for competitive strategy

incorporating reference price effects into a theory of consumer choice although there has been a good deal of research on incorporating the effects of reference price formation into empirical models of consumer buying behavior little formal theoretical work had been undertaken to date this paper incorporates reference price effects into the traditional economic theory of consumer choice and examines the effects of reference price formation on the results of the traditional theory its marketing implications and the implications for empirical models which examine the effects of reference price formation on actual consumer behavior several implications of the theoretical model are empirically tested using weekly retail egg sales data from southern california this analysis indicates that reference price formation does have significant effects on consumer behavior furthermore these effects are asymmetric with consumers two and a half times more responsive to egg price increases that are in excess of the reference price than they are to comparable egg price decreases

testing the moderating role of financial development in an environmental kuznets curve empirical evidence from turkey abstract employing second generation econometric procedures that consider multiple structural breaks in the series this article examines turkey as a case study in the investigation of the moderating role of financial development in a conventional environmental kuznets curve ekc the study uses two separate models for this purpose 1 the main effects model and 2 the interaction effects model the results of this investigation suggest a long term equilibrium relationship between financial development and the ekc in turkey using both model options financial development has been found to moderate the effect of real output on carbon dioxide emissions in the shorter periods negatively which signifies successful environmental performance and energy management in comparison financial development moderates the effect of real output on carbon dioxide emissions in the longer periods positively and in which this finding again signifies that policies for energy savings and green house targets need to be established to target longer periods and energy management policies at higher levels of economic activity the present study did not confirm a significant moderating effect of financial development on the impact of energy consumption on carbon dioxide emissions in the case of turkey

the environmental kuznets curve economic growth renewable and non renewable energy and trade in tunisia we use the autoregressive distributed lag ardl b ounds testing approach for cointegration with structural breaks and the ve ctor error correction model vecm granger causality approach in order to investigate relationships between per capita co 2 emissions gdp renewable and non renewable energy consumption and international trade exports or imports for tunisia during the period 1980 2009 we show the existence of a short run unidirectional causality running from tra de gdp co 2 emission and non renewable energy to renewable energy our long run estimates show that non renewable energy and trade have a positive impact on co 2 emissions whereas renewable energy impacts weakly and negatively co 2 emission when using the model with exports and this impact is statistically insignificant when using the model wi th imports the inverted u shaped environmental kuznets curve ekc hypothesis is not supported graphically and analytically in the long run this means that tunisia has not ye t reached the required level of per capita gdp to get an inverted u shaped ekc our main policy recommendations for tunisia are the following i to radically reform the subsidies system granted b y the tunisian government for fossil fuels consumption ii to encourage the use of renewable energy and ener gy efficiency by reinforcing actual projects and regulatory frame work iii to locate ports near exporting industrial zones or vice versa to reduce emission of pollution caused by the transport of merchandise iv to elaborate a strategy for maximizing its benefit from renewable energy technology transfer occurring when importing capita l goods v to encourage the creation of renewable energy projects for export to the eu with a proportion of production for national consumption

the effect of local consideration sets on global choice between lower price and higher quality a set of alternatives under consideration is often divided into subsets or local sets by some external e g product display format at the store or internal e g a decision rule factor we propose that the manner in which a global set of alternatives varying in price and quality is divided into local sets can have a systematic effect on consumer choice between a lower price alternative and a higher quality alternative three such effects are investigated 1 consumers who first choose from pairs of products a b b c a c and then choose from the set of all three products a b c are more likely to prefer the cheapest alternative than consumers who only choose from the complete set 2 the choice share of a low price low quality brand is greater when alternatives varying in price quality and features are displayed by brand i e each display presents different models of one brand as compared to a display by feature level i e each display presents comparable models of different brands and 3 consumers considering a pair of two option local sets each consisting of different brands and feature levels e g a feature enhanced model of a low quality brand vs a basic model of a high quality brand are more likely to select a feature enhanced model from the global set of four options than those who consider the same alternatives in other local set configurations or consider only the global set these predictions were supported in seven studies which also provided insights into the boundaries of the effects focusing on the paired comparison effect we discuss the theoretical and practical implications of the findings

free entry and social inefficiency our goal is to provide a simple yet general exposition of the conditions under which the number of entrants in a free entry equilibrium is excessive insufficient or optimal our analysis compares the number of firms that enter a market when there is free entry with the number that would be desired by a social planner who is unable to control the behavior of firms once they are in the market that is we consider the second best problem of choosing the welfare maximizing number of firms while we take as given their noncompetitive behavior after entry we demonstrate that the crucial conditions for establishing the presence of an entry bias can be stated quite simply in terms of the outcome of the postentry game played by entrants in contrast to previous work we do not need to model this postentry game explicitly

co2 emissions energy consumption trade and income a comparative analysis of china and india in order to prevent the destabilisation of the earth s biosphere co2 emissions must be reduced quickly and significantly the causes of co2 emissions by individual countries need to be apprehended in order to understand the processes required for reducing emissions around the globe china and india are the two largest transitional countries and growing economies but are in two entirely different categories in terms of structural changes in growth trade and energy use co2 emissions from the burning of fossil fuels have significantly increased in the recent past this paper compares china and india using the bounds testing approach to cointegration and the ardl methodology to test the long and short run relationships between growth trade energy use and endogenously determined structural breaks the co2 emissions in china were influenced by per capita income structural changes and energy consumption a similar causal connection cannot be established for india with regard to structural changes and co2 emissions because india s informal economy is much larger than china s india possesses an extraordinarily large number of micro enterprises that are low energy consumers and not competitive enough to reach international markets understanding these contrasting scenarios is prerequisite to reaching an international agreement on climate change affecting these two countries

choosing what i want versus rejecting what i do not want an application of decision framing to product option choice decisions abstract the authors examine the effects of using a subtractive versus an additive option framing method on consumers option choice decisions in three studies the former option framing method presents consumers with a fully loaded product and asks them to delete options they do not want the latter presents them with a base model and asks them to add the options they do want combined the studies support the managerial attractiveness of the subtractive versus the additive option framing method consumers tend to choose more options with a higher total option price when they use subtractive versus additive option framing this effect holds across different option price levels study 1 and product categories of varying price study 2 moreover this effect is magnified when subjects are asked to anticipate regret from their option choice decisions study 2 however option framing has a different effect on the purchase likelihood of the product category itself depending on the subject s initial inter

environmental kuznets curve for co2 in canada abstract according to the environmental kuznets curve hypothesis the relationship between per capita gdp and per capita pollutant emissions has an inverted u shape this implies that past a certain point economic growth may actually be profitable for environmental quality most studies on this subject are based on estimating fully parametric quadratic or cubic regression models while this is not technically wrong such an approach somewhat lacks flexibility since it may fail to detect the true shape of the relationship if it happens not to be of the specified form we use semiparametric and flexible nonlinear parametric modeling methods in an attempt to provide more robust inferences we find little evidence in favour of the environmental kuznets curve hypothesis our main results could be interpreted as indicating that the oil shock of the 1970s has had an important impact on progress towards less polluting technology and production

investigation of the environmental kuznets curve for carbon emissions in malaysia do foreign direct investment and trade matter abstract environmental degradation has become a central issue of discussion among the economists and environmentalists in view of malaysia s position as one of the main contributors to co2 emissions in asia and its status as a fast growing economy it is vital therefore to conduct a study to identify the relationship between economic growth and co2 emissions for malaysia this study attempts to examine empirically the environmental kuznets curve hypothesis for malaysia in the presence of foreign direct investment and trade openness both in the short and long run for the period 1970 to 2008 the bounds testing approach and granger causality methodology are applied to test the interrelationships of the variables the results of our study indicate that the inverted u shaped relationship does exist between economic growth and co2 emission in both the short and long run for malaysia after controlling for two additional explanatory variables namely fdi and trade importantly the results of the study also provide some crucial policy recommendations to the policy makers

the impact of growth energy and financial development on the environment in china a cointegration analysis this article aims to investigate the impact of financial development economic growth and energy consumption on environmental pollution in china from 1953 to 2006 using the autoregressive distributed lag ardl bounds testing procedure the main objective is to examine the long run equilibrium relationship between financial development and environmental pollution the results of the analysis reveal a negative sign for the coefficient of financial development suggesting that financial development in china has not taken place at the expense of environmental pollution on the contrary it is found that financial development has led to a decrease in environmental pollution it is concluded that carbon emissions are mainly determined by income energy consumption and trade openness in the long run moreover the findings confirm the existence of an environmental kuznets curve in the case of china

energy innovations ghg emissions nexus fresh empirical evidence from oecd countries abstract this study explores the impact of improvements in energy research development erd on greenhouse gas ghg emissions using environmental kuznets curve hypothesis for 28 oecd countries over the period of 1990 2014 in doing so we have employed a panel data where public budget in energy research development and demonstration erd d has transformed into a finite inverted v lag distribution model developed by de leeuw 1962 this model considers that energy innovation accumulates in time and presents empirical evidence how energy innovation contributes in reducing energy intensity and environmental pollution as well our results indicate that energy innovation measures require lapses of time to reach their full effect i e innovation applied to measures for environmental correction does not reach its whole effect immediately requiring instead a certain amount of time to pass innovation policies have recommended for improving environmental quality

adding asymmetrically dominated alternatives violations of regularity and the similarity hypothesis an asymmetrically dominated alternative is dominated by one item in the set but not by another adding such an alternative to a choice set can increase the probability of choosing the item that dominates it this result points to the inadequacy of many current choice models and suggests product line strategies that might not otherwise be intuitively plausible

information aggregation in a noisy rational expectations economy abstract this paper analyzes a general equilibrium model of a competitive security market in which traders possess independent pieces of information about the return of a risky asset each trader conditions his estimate of the return both on his own private source of information and price which in equilibrium serves as a noisy aggregator of the total information observed by all traders a closed form characterization of the rational expectations equilibrium is presented a counter example to the existence of fully revealing equilibrium is developed

dynamic linkages among transport energy consumption income and co2 emission in malaysia this paper examines the dynamic relationship between income energy use and carbon dioxide co2 emissions in malaysia using time series data during 1975 to 2011 this study also attempts to validate the environmental kuznet curve ekc hypothesis applying a multivariate model of income energy consumption in the transportation sector carbon emissions structural change in the economy and renewable energy use the empirical evidence confirmed that there is a long run relationship between the variables as shown by the result of co integration analysis the results indicate that the inverted u shape ekc hypothesis does not fully agree with the theory the coefficient of squared gdp is not statistically different from zero the time duration and the annual data used for the present study do not seem to strongly validate the existence of ekc hypothesis in the case of malaysia causality test shows that the relationship between gdp and co2 is unidirectional the granger causality test results reveal that emissions granger cause income energy consumption and renewable energy use moreover we find that income granger causes energy consumption and renewable energy use and both structural change and renewable energy use granger cause energy consumption in road transportation

price induced patterns of competition this research focuses on how price changes influence the observed pattern of brand competition the paper begins with a basic utility model formulation and examines the implications of three major classes of preference distributions on the expected patterns of competition a price tier model is proposed to operationalize the theory and to allow predictive testing the price tier model is estimated on 28 brands across four product categories the results show a specific asymmetric pattern of price competition higher price higher quality brands steal share from other brands in the same price quality tier as well as from brands in the tier below however lower price lower quality brands take sales from their own tier and the tier below brands but do not steal significant share from the tiers above the results are consistent with a bimodal preference distribution with the regular price indifference point being located toward the lower quality end of the preference distribution for the categories analyzed

the role of renewable energy to validate dynamic interaction between co2 emissions and gdp toward sustainable development in malaysia abstract closing the gap between economy activity and environmental quality is one of the solutions for reaching sustainable development in malaysia to do so the cubic polynomial functional form of ekc is utilized by accommodating renewable energy into the base of the ekc model and validating its hypothesis between co 2 emissions and gdp growth for the 1971 2015 period the f bounds vecm granger causality cusum and cusumsq tests are utilized the estimated results consistently show that the inverted n shaped ekc hypothesis holds in malaysia ceteris paribus the co 2 emissions will be declined when the gdp reach rm2841 9 billion in 2030 which is beyond the sample period the renewable energy has a negative significant effect on co 2 emissions and the direction of causality is running from co 2 emissions to renewable energy also the gdp growth will be the remedy for environmental pollution problems and that renewable energy is one of important elements to be considered for improving environmental quality a tighter and concentrated environmental policy is needed to direct the environment economic growth nexus toward a downward trend consequently these results may help malaysian policymakers to establish an energy policy that guarantees a balance between economic growth and environmental prosperity

environmental kuznets curve in an open economy a bounds testing and causality analysis for tunisia the environmental kuznets curve hypothesis posits that in the early stages of economic growth environmental degradation and pollution increase however as a nation reaches a certain level of incom

trade the pollution haven hypothesis and the environmental kuznets curve examining the linkages abstract this paper examines the extent to which the ekc inverted u relationship can be explained by trade and specifically the migration or displacement of dirty industries from the developed regions to the developing regions the pollution haven hypothesis phh using detailed data on north south trade flows for pollution intensive products the evidence for the phh is assessed emissions of 10 air and water pollutants are then estimated controlling for trade openness structural change and dirty north south trade flows evidence of pollution haven effects is found although such effects do not appear to be widespread and appear to be relatively small compared to the roles played other explanatory variables

re visiting the environmental kuznets curve hypothesis for malaysia fresh evidence from ardl bounds testing approach abstract this study reinvestigates the presence of environmental kuznets curve ekc in the context of malaysia over the period of 1971 2012 for this purpose the impact of real gdp per capita financial development trade openness foreign direct investments and energy consumption on carbon dioxide co2 emissions is empirically examined within the ekc framework the study employed the autoregressive distribute lagged ardl bound test to investigate the long run relationship between the study variables for robustness the study conjointly applied the dynamic ordinary least square dols method the granger causality test is exercised to test the causal relationship among the variables for both short and long run empirical results of ardl bound test approach suggest the presence of ekc hypothesis for malaysia the granger causality test results indicate that energy consumption and carbon emissions have a bidirectional relationship while other variables uni directionally cause the co2 emissions whereas in the short run there is no bidirectional causality between the variables while uni directional causalities run from trade openness and fdi towards economic growth financial development and co2 emissions the unidirectional causality from other variables towards co2 emissions supports the evidence of the environmental kuznets curve hypothesis as this appears in the countries where the ekc is validated

dynamic misspecification in the environmental kuznets curve evidence from co2 and so2 emissions in the united kingdom this study looks at the behaviour of emissions when in disequilibrium with respect to the environmental kuznets curve ekc relationship we use the non linear threshold cointegration and error correction methodology and a long dataset beginning in 1830 in an application to the united kingdom there is significant evidence that not only does the inverse u shape hold between per capita co 2 and so 2 emissions and gdp per capita but we also find that temporary disequilibrium from the long run ekc is corrected in an asymmetric fashion this may be due to the historical pressure of environmental regulation in the uk to reduce emissions that are higher than permitted however further analysis suggests that technological change can partially account for the asymmetric adjustment

the dynamic impact of renewable energy consumption on co2 emissions a revisited environmental kuznets curve approach this paper considers a revisited environmental kuznets curve ekc hypothesis with potential impact of renewable energy consumption on environmental quality to this end paper aims at investigating the validity of the ekc hypothesis employing the dependent variable of co2 emissions and regressors of gdp quadratic gdp and renewable energy consumption this paper hence analyzes this revisited ekc hypothesis to observe if i there exists an inverted u shaped relationship between environmental quality in terms of co2 emissions per capita income and per capita income squared and ii there exists a negative causality from renewables to co2 emissions within ekc model paper employs a panel data set of 17 oecd countries over the period 1977 2010 and launches panel fmols and panel dols estimations the findings support the ekc hypothesis for the panel and indicate that gdp per capita and gdp per capita squared have the impacts on co2 emissions positively and negatively respectively and that renewable energy consumption yields negative impact on co2 emissions another remark of this paper is that the validity of ekc does not depend on income level of individual countries of panel in which ekc hypothesis holds eventually paper argues that if countries carry out i policies i e for fair and easy access to the electricity from renewable sources and ii policies to increase renewables supply through i e improved renewable energy technologies they will be able to contribute to combating global warming problem as they increase their gdp s

ghg emissions gdp growth and the kyoto protocol a revisit of environmental kuznets curve hypothesis abstract the kyoto protocol attempts through political negotiations to guide participating industrialized countries greenhouse gas ghg emissions from a positive growing trend to reach a peak point or turning point and then be reduced to a negative growth that means the relationship between decreasing ghg emissions and economic growth may be described by an inverted u curve or called a bell shaped curve which is consistent with the concept of the environmental kuznets curve ekc hypothesis this research observed that the economic development and ghg emissions in economies in transition eits exhibit a hockey stick curve trend or called quasi l shape curve that also generates a lot of hot air which is significant to the implementation of the kyoto protocol in addition through the analysis of single country time series data and gdp data this research demonstrated that statistical data for most of the annex ii countries do not possess evidence that supports the ekc hypothesis for ghg emissions the results from this study also indicated that the 38 industrialized countries are unable to meet their targets under the kyoto protocol within the specified time period which are probably caused by the econometric method s inability to predict accurately the extents and development of innovative technologies and clean development mechanism cdm projects if the international community truly wants to reduce the ghg emissions the effectiveness of the existing international framework for emissions reduction needs to be reconsidered seriously and the global cooperation mechanism also needs to be greatly enhanced

energy policy for low carbon development in nigeria a leap model application this paper applied a scenario based analysis to explore nigeria s future energy demand supply and associated ghg emissions from 2010 to 2040 using the long range energy alternative planning leap model the impact of different energy policies are analysed for the nigerian energy system by considering four scenarios the reference scenario ref the low carbon moderate scenario lcm the low carbon advanced scenario lca and the green optimistic scenario go by considering aggressive energy policies and strategies from lcm to lca and even more aggressive options in the go scenario we find that under the ref scenario energy demand is expected to reach 3 075 pj and a corresponding increase in ghg emissions of 201 2 mt co2e by 2040 more aggressive policy intervention by the nigerian government as in the go scenario would lead to a decrease in energy demand 2 249 pj and ghg emissions 124 4 mt co2e in 2040 a cost benefit and energy system analysis were also carried out in the study

energy conservation policies growth and trade performance evidence of feedback hypothesis in pakistan this study investigates the relationship between energy consumption and trade openness in pakistan by using the annual time series data for the period of 1973 2011 our main results show i the presence of long run link between energy consumption and trade performance ii positive impact of gross domestic product exports and imports on energy consumption iii bidirectional causal relationship between exports and energy consumption and also be tween imports and energy demand and iv bidirectional causality between gross domestic product and energy consumption points to the presence of feedback hypothesis in pakistan we therefore note that energy conservation policies will reduce the trade performance which in turn leads to the decline in economic growth in pakistan the present study may guide policymakers in formulating a conclusive energy and trade policies for sustainable growth for long span of time

context dependent preferences the standard theory of choice based on value maximization associates with each option a real value such that given an offered set the decision maker chooses the option with the highest value despite its simplicity and intuitive appeal there is a growing body of data that is inconsistent with this theory in particular the relative attractiveness of x compared to y often depends on the presence or absence of a third option z and the market share of an option can actually be increased by enlarging the offered set we review recent empirical findings that are inconsistent with value maximization and present a context dependent model that expresses the value of each option as an additive combination of two components a contingent weighting process that captures the effect of the background context and a binary comparison process that describes the effect of the local context the model accounts for observed violations of the standard theory and provides a framework for analyzing context dependent p

impact of urbanization growth on malaysia co2 emissions evidence from the dynamic relationship abstract urbanization is a phenomenon of economic and social modernization investigating the link between urbanization growth and co2 emissions is necessary and helpful for malaysia to achieve its pollution reduction targets ecological modernization and augmented cobb douglas production theories are used in order to gain the best understanding of interaction between co2 emissions and urbanization for the 1971 2015 period this study aims to examine the relationships among co2 emissions urbanization growth energy consumption gdp domestic investment and financial development the f bounds test and vecm granger causality are utilized the dynamic relationship among variables and the inverted u shaped relationship between co2 emissions and urbanization in the long run are examined the elasticity of co2 urbanization is found positive elastic in the early stage of urbanization but it turns to negative inelastic at the higher urbanization stage furthermore the unidirectional causality from urbanization to co2 emissions in the short run are at a 1 percent level of significance and the bidirectional causality between co2 emissions and urbanization is at a 5 percent level of significance in the long run also we captured bidirectional causality among energy consumption domestic investment gdp co2 emissions and unidirectional causality from financial development to co2 emissions at least at a 5 percent level of significance these findings could support policymakers in managing urbanization development and considering clean investment and other green aspects for urban sustainable development which can save many people from natural disaster

speculative profits innovation and growth when technological change affects the prices of tradeable assets innovators can obtain speculative profits by exploiting their inside information as to the occurrence of innovations we propose a tractable model of endogenous growth that formalizes this argument originally due to hirshleifer 1971 we then use the model to assess two claims advanced by hirshleifer namely that speculative profits can generate excessive investment in r d when they add to monopoly rents guaranteed by patent protection or else even in a perfectly competitive economy the analysis confirms the first claim but casts doubts on the second one jel o30 o40

the co2 emissions income nexus evidence from rich countries the paper attempts to test the environment kuznets curve ekc hypothesis for 36 high income countries for the period 1980 2005 the test is based on the suggestion of narayan and narayan 2010 various panel data unit root and co integration tests are applied carbon dioxide co2 emissions and gdp series are integrated of order one and co integrated especially after controlling for cross sectional dependence additionally the blundell bond system generalised methods of moments gmm is employed to conduct a panel causality test in a vector error correction mechanism vecm setting unidirectional causality running from real per capita gdp to per capita co2 emissions is uncovered in both the short run and the long run the empirical analysis based on individual countries provides evidence of an ekc for greece malta oman portugal and the united kingdom however it can be observed that for the whole panel a 1 increase in gdp generates an increase of 0 68 in co2 emissions in the short run and 0 22 in the long run the lower long run income elasticity does not provide evidence of an ekc but does indicate that over time co2 emissions are stabilising in the rich countries

environment kuznets curve for co2 emissions a cointegration analysis for china abstract this study examines the long run relationship between carbon emissions and energy consumption income and foreign trade in the case of china by employing time series data of 1975 2005 in particular the study aims at testing whether environmental kuznets curve ekc relationship between co 2 emissions and per capita real gdp holds in the long run or not auto regressive distributed lag ardl methodology is employed for empirical analysis a quadratic relationship between income and co 2 emission has been found for the sample period supporting ekc relationship the results of granger causality tests indicate one way causality runs through economic growth to co 2 emissions the results of this study also indicate that the carbon emissions are mainly determined by income and energy consumption in the long run trade has a positive but statistically insignificant impact on co 2 emissions

bounds testing approach to analysis of the environment kuznets curve hypothesis abstract this paper examines the long run and the dynamic temporal relationships between economic growth energy consumption population density trade openness and carbon dioxide co 2 emissions in brazil china egypt japan mexico nigeria south korea and south africa based on the environment kuznets curve ekc hypothesis we employ the ardl bounds test to cointegration and cusum and cusumsq tests to ensure cointegration and parameter stability the estimated results show that the inverted u shaped ekc hypothesis holds in japan and south korea in the other six countries the long run relationship between economic growth and co 2 emissions follows an n shaped trajectory and the estimated turning points are much higher than the sample mean in addition the results indicate that energy consumption granger causes both co 2 emissions and economic growth in all the countries our results are consistent with previous studies that show that there is no unique relationship between energy consumption population density economic growth trade openness and the environment across countries

economic growth and co2 emissions in malaysia a cointegration analysis of the environmental kuznets curve this paper attempts to establish a long run as well as causal relationship between economic growth and carbon dioxide co2 emissions for malaysia using data for the years from 1980 to 2009 the environmental kuznets curve ekc hypothesis was tested utilizing the auto regressive distributed lag ardl methodology the empirical results suggest the existence of a long run relationship between per capita co2 emissions and real per capita gross domestic product gdp when the co2 emissions level is the dependent variable we found an inverted u shape relationship between co2 emissions and gdp in both short and long run thus supporting the ekc hypothesis the granger causality test based on the vector error correction model vecm presents an absence of causality between co2 emissions and economic growth in the short run while demonstrating uni directional causality from economic growth to co2 emissions in the long run

optimal product line design when consumers exhibit choice set dependent preferences in a market of consumers with varying willingness to pay using product line as a discrimination tool may extract higher profits than serving all consumers with a single product local context effects however point to yet another consideration in designing product lines how the appeal of a product changes with the context provided by other products in the choice set i present a model of product line design that incorporates both discrimination and context management goals and offers recommendations for the variety and positioning of products to this end the model makes use of a framework that allows preferences to be choice set dependent given this framework i study how the firm manages externalities between products created by such dependencies the firm creates distortions above and beyond those resulting from discrimination motives alone for example in a vertically differentiated market for quality quality distortions exist even for the consumers with the highest valuations the range of quality provisions given the number of products is compressed as the relative importance of unfavorable comparisons among products increases surprisingly this compression may even lead the firm to forego discrimination among consumers regardless of the cost of offering distinct products

choice based on reasons the case of attraction and compromise effects building on previous research this article proposes that choice behavior under preference uncertainty may be easier to explain by assuming that consumers select the alternative supported by the best reasons this approach provides an explanation for the so called attraction effect and leads to the prediction of a compromise effect consistent with the hypotheses the results indicate that 1 brands tend to gain share when they become compromise alternatives in a choice set 2 attraction and compromise effects tend to be stronger among subjects who expect to justify their decisions to others and 3 selections of dominating and compromise brands are associated with more elaborate and difficult decisions

income distribution and co2 emission a comparative analysis for china and india abstract the aim of this paper is to test whether income inequality contributes to environmental degradation in china and india where both countries are giving a great concern about the implications of their unsustainable energy consumption to the environment not only to themselves but also to the global environmental sustainability by applying the bounds test approach to cointegration we found in both countries a long run but not a statistically significant relationship between income inequality and co 2 emissions both in the long run and in the short run the robustness of our cointegration results is also ascertained by using three different long run tests furthermore applying the variance decomposition analysis to examine the dynamic causal relationship between the gini coefficient of income distribution and co 2 emissions we found that income inequality was the least important factor in determining co 2 emissions and that there was no causality running in any direction between co 2 emissions and income inequality in both countries still income and energy consumption are the major determinants of co 2 emissions in both countries nevertheless even though the evidence is not statistically significant in the case of china it indicates that reducing income inequality can have a positive impact on environmental quality while in india redistributing income to improve environmental degradation may not be effective

literature survey on the relationships between energy environment and economic growth abstract the aim of this study is to exhibit an exhaustive survey which is related to the great flight of the literature of energy environment growth nexus at the individual and regional scale studies covering the period from 1978 to 2014 the survey takes into consideration the sample country region etc periods covering econometric strategies and conclusions our survey is based on the causality direction among i the energy use variables electricity nuclear renewable and non renewable and output growth ii between economic growth and environment and between the three variables at the same time globally these surveys provide paradoxical and not conclusive results which energy consumption can boost economic growth through the productivity enhancement and it can boost also the environmental damages through the enhancement of pollutant emissions our survey sheds more the lights on the energy environment growth literature by giving an extensive listing 1978 2014 of these causal linkages among the energy use variables environment and economic growth for both individual and collective cases there is a unanimous consensus about the importance of dealing with such dynamic relationship which is seems to be a cornerstone element in setting any ambition strategies energy ecological and economics

co2 emissions energy consumption economic and population growth in malaysia abstract this study investigates the dynamic impacts of gdp growth energy consumption and population growth on co2 emissions using econometric approaches for malaysia empirical results from ardl bounds testing approach show that over the period of 1970 1980 per capita co2 emissions decreased with increasing per capita gdp economic growth however from 1980 to 2009 per capita co2 emissions increased sharply with a further increase of per capita gdp this is also supported by the dynamic ordinary least squared dols and the sasabuchi lind mehlum u slm u test tests consequently the hypothesis of the ekc is not valid in malaysia during the study period the results also demonstrate that both per capita energy consumption and per capita gdp has a long term positive impacts with per capita carbon emissions but population growth rate has no significant impacts on per capita co2 emission however the study suggests that in the long run economic growth may have an adverse effect on the co2 emissions in malaysia thus significant transformation of low carbon technologies such as renewable energy and energy efficiency could contribute to reduce the emissions and sustain the long run economic growth

is the environmental kuznets curve hypothesis a sound basis for environmental policy in africa achieving economic development and environmental sustainability simultaneously is one of the most important development challenges for africa today the relationship between economic growth and environmental sustainability is founded on the environmental kuznets curve ekc this paper examines the validity of the hypothesis and the driving factors of carbon dioxide co2 emission in five african countries using the stirpat empirical model panel cointegration and fully modified ordinary least squares unlike previous studies economic development is disaggregated into agriculture and industrial economic development the results show that there is no evidence of the validity of the hypothesis in africa regardless of whether economic development is driven by agriculture or industrialisation energy structure and energy intensity are the two major driving forces of co2 emissions in africa population growth and urbanisation have negative relationship with co2 emissions from our results the ekc is not a sound basis for environmental policy in africa rather environmental policy in africa specifically for co2 emissions mitigation should focus on encouraging energy efficiency enhancing the use of clean energy incorporating the impact of population growth and harnessing the positive impacts of urbanisation

energy consumption carbon emissions and economic growth in china abstract this paper investigates the existence and direction of granger causality between economic growth energy consumption and carbon emissions in china applying a multivariate model of economic growth energy use carbon emissions capital and urban population empirical results for china over the period 1960 2007 suggest a unidirectional granger causality running from gdp to energy consumption and a unidirectional granger causality running from energy consumption to carbon emissions in the long run evidence shows that neither carbon emissions nor energy consumption leads economic growth therefore the government of china can purse conservative energy policy and carbon emissions reduction policy in the long run without impeding economic growth

renewable energy carbon emission and economic growth a revised environmental kuznets curve perspective abstract renewable energy plays an important role in reducing global carbon co2 emission this paper builds a rer renewable energy consumption rate index to represent the energy structure of a country and proposes a u shaped rkc renewable energy kuznets curve hypothesis between rer and economic growth we also examine the dynamic relationship between rer and the environmental kuznets curve ekc hypothesis using two panel data sets of 17 major developing and developed countries as well as six geo economic regions of the world during 1990 2014 panel co integration tests indicate that a long run relationship exists among economic growth rer and carbon emission we employ the fully modified ordinary least squares fmols and the dynamic ordinary least squares dols techniques to estimate the co integration coefficients of the panels and individual countries regions respectively the results verify both the ekc and rkc hypotheses indicating that a 10 rise in rer would to a 1 6 carbon emission reduction it is also found that the rkc turning points of individual countries and the entire samples in general take place before the turning points of the respective ekcs it suggests that promoting renewable energy consumption to make rkc cross its turning point earlier can accelerate ekc to reach its turning point more quickly this finding has important policy implications with respect to the development and utilization of renewable energy and environmental protection

carbon emission energy consumption trade openness and financial development in pakistan a revisit the paper empirically examines the cointegrating relationship between carbon emissions energy consumption trade openness and financial development in pakistan using ardl bounds test for cointegration procedure annual time series data is used for the period 1971 2011 the results reveal an inverted u shaped relationship between carbon emission and energy consumption with a maximum threshold value of energy consumption per capita 640 kg of oil equivalent currently the economy is operating below this level and therefore it is expected that carbon emission will continue to rise gradually over some time until the threshold level is reached the lower than threshold level of energy consumption implies that scale and composition effects dominate the technology effect in terms of energy use further the long run results indicate that one percent increase in trade openness and financial development will increase carbon emission by 0 247 and 0 165 respectively the short run elasticities are 0 122 and 0 087 for trade openness and financial development respectively the granger causality results indicate a unidirectional causality from energy consumption trade openness and financial development to carbon emission and a bi directional causality between energy consumption and financial development in line with the results and given the growing focus on climate change effects in pakistan the paper discusses some policy issues for consideration and highlights the need to interpret elasticities with caution

exploring the relationship between urbanization energy consumption and co2 emission in mena countries abstract this study explored the relationship between urbanization energy consumption and co2 emission in the mena countries the panel model was utilized taking the period 1980 2009 into consideration pedroni cointegration test results showed that urbanization energy consumption and co2 emission were cointegrated the dynamic ols results also showed that there was a long run bi directional positive relationship between urbanization energy consumption and co2 emission however the significance of the long run relationship between urbanization energy consumption and co2 emission varied across the countries based on their level of income and development moreover long and short run bi directional causal relationships were found between the variables based on the granger causality test results from the results of this study it is important for the urban planners and policy makers in the mena countries to slow the rapid increase in urbanization the level of energy consumption and co2 emission in the mena countries increased more than double thus slowing down the urbanization level can help reduce the level of pollution and energy consumption in addition the increased energy efficiency implementation of energy savings projects energy conservation and energy infrastructure outsourcing reduce the level of pollution produced by urban areas

the link between green taxation and economic growth on co2 emissions fresh evidence from malaysia abstract this paper explores how carbon taxation and economic growth affect environment hazards in malaysia using time series data over the period 1974 2010 we applied cointegration and causality approaches to determine the long term cointegration and direction of causal relationship between these variables based on the results we found the cointegration relationship between the variables furthermore we noted that although kuznets theory i e inverted u shaped curve between economic growth and co 2 emissions is valid for malaysia the carbon taxation policy is ineffective to control co 2 emissions the causality analysis revealed that there is a bidirectional relationship between carbon tax and co 2 emissions economic growth granger causes co 2 emissions and carbon tax granger causes economic growth to enhance the awareness concerning pollution issues governments should rely on alternative instruments that may give benefit to the taxpayers and reduce pollution which is the pivotal issue to be tackled globally

what causes over investment in r d in endogenous growth models endogenous growth models may exhibit either under or over investment in r d the possibility of over investment is generally attributed to a business stealing effect that arises as the latest innovator destroys and or appropriates previous incumbent s rents we argue that this conventional wisdom is misleading in standard models business stealing by itself cannot result in excessive r d we explain the other effects that must be at work here thus contributing towards a better understanding of when and why the market may be biased towards excessive r d

co2 emissions energy consumption and output in france abstract this paper examines the dynamic causal relationships between pollutant emissions energy consumption and output for france using cointegration and vector error correction modelling techniques we argue that these variables are strongly inter related and therefore their relationship must be examined using an integrated framework the results provide evidence for the existence of a fairly robust long run relationship between these variables for the period 1960 2000 the causality results support the argument that economic growth exerts a causal influence on growth of energy use and growth of pollution in the long run the results also point to a uni directional causality running from growth of energy use to output growth in the short run

energy consumption and gdp in turkey is there a co integration relationship energy consumption and gdp are expected to grow by 5 9 and 7 annually until 2025 in turkey this paper tries to unfold the linkage between energy consumption and gdp by undertaking a co integration analysis for turkey with annual data over the period 1970 2003 the analysis shows that energy consumption and gdp are co integrated this means that there is a possibly bi directional causality relationship between the two we establish that there is a unidirectional causality running from gdp to energy consumption indicating that energy saving would not harm economic growth in turkey in addition we find that energy consumption keeps on growing as long as the economy grows in turkey

energy consumption economic growth and co2 emissions in middle east and north african countries this article extends the recent findings of liu 2005 ang 2007 apergis et al 2009 and payne 2010 by implementing recent bootstrap panel unit root tests and cointegration techniques to investigate the relationship between carbon dioxide emissions energy consumption and real gdp for 12 middle east and north african countries mena over the period 1981 2005 our results show that in the long run energy consumption has a positive significant impact on co2 emissions more interestingly we show that real gdp exhibits a quadratic relationship with co2 emissions for the region as a whole however although the estimated long run coefficients of income and its square satisfy the ekc hypothesis in most studied countries the turning points are very low in some cases and very high in other cases hence providing poor evidence in support of the ekc hypothesis co2 emission reductions per capita have been achieved in the mena region even while the region exhibited economic growth over the period 1981 2005 the econometric relationships derived in this paper suggest that future reductions in co2 emissions per capita might be achieved at the same time as gdp per capita in the mena region continues to grow

the saving and investment nexus for china evidence from cointegration tests the saving and investment nexus as postulated by feldstein and horioka fh 1980 is revisited the saving investment correlation for china is estimated over the periods 1952 1998 and 1952 1994 the latter culminating in a period of fixed exchange rate regime amongst the key results it is found that saving and investment are correlated for china for both the period of the fixed exchange rate and the entire sample period with high saving investment correlation the results suggest that the chinese economy is in conformity with the fh hypothesis this is a valid outcome for in china capital mobility was fairly restricted over the 1952 1994 period as indicated by the relatively low foreign direct investment
