economic tactics commercial policy and the socialization of african agriculture abstract commercial policies in some african countries have come under considerable criticism in recent years and it has become necessary to resolve the problems of existing agricultural marketing forms an alternative approach to the market liberalization commonly recommended is to intervene in the market so as to achieve its regulation and control and a pricing system which can and will support the socialization of agricultural production in collective farms maintain incentives for individual producers and encourage state procurement of basic crops such market control cannot be achieved without an active commercial policy based on the transformation of marketing institutions effective forms of market intervention and the devolution of considerable power over pricing and marketing from the national to the local levels

primitive accumulation agrarian reform and socialist transitions an argument this essay constructs a preliminary argument concerning the position of the peasantry in the twin transitions the first to industrialisation and the second towards socialism within orthodox marxian theory the two transitions are also sequential with the socialist order emerging from the crisis breakdown and overthrow of the capitalist system which in its maturity becomes a fetter upon further development and begets with the inexorability of a law of nature its own negation marx 1969 144 at this juncture the process of proletarianisation has been completed in the economy as a whole including the agricultural sector where the petty peasant producers and artisans have been separated from their means of production and have been reduced to the status of sellers of labour power while the landlords and or sections of the middle and rich peasantry have emerged as capitalist farmers who treat agriculture as a branch of industry integrated fully with the rest of the economy however this bit of marx s theory of history was drafted without the benefit of hindsight and thus far history has resisted conforming to what was expected of it the first socialist revolution broke the capitalist chain not at the strongest but rather at the weakest link and subsequent socialist transitions have also been initiated through revolutionary movements in arenas which display low initial levels of economic especially industrial development at the time of the revolutionary break with the past none of the present roll of socialist economies boasted an advanced industrial sector in none of them was the process of rural proletarianisation anywhere near completion indeed in most cases on both counts the situation was as far from the marxian postulation as could be imagined as such these countries have entered the socialist transition not through the crossroads of industrialisation instead they have launched upon the twin transitions simultaneously

on the robustness of robustness checks of the environmental kuznets curve hypothesis since its first inception in the debate on the relationship between environment and growth in 1992 the environmental kuznets curve hypothesis ekc hereafter has been subject of continuous and intense scrutiny the most recent line of investigation criticizes the ekc hypothesis on more fundamental grounds in that it stresses the lack of sufficient statistical testing of the empirical relationship and questions the very existence of the notion of ekc attention is in particular drawn on the stationarity properties of the series involved per capita emissions or concentrations and per capita gdp and in case of presence of unit roots on the cointegration property that must be present for the ekc to be a well defined concept only at that point can the researcher ask whether the long run relationship exhibits an inverted u pattern on the basis of panel integration and cointegration tests for sulfur stern 2004 and perman and stern 1999 2003 have presented evidence and forcefully stated that the ekc hypothesis does not exist in this paper we ask whether similar strong conclusions can be arrived at when carrying out tests of system fractional integration and cointegration as an example we use the controversial case of carbon dioxide emissions the results show that more ekcs come back into life relative to traditional integration cointegration tests however we confirm that the ekc hypothesis remains a fragile concept

a dynamic approach to the environmental kuznets curve hypothesis abstract the environmental kuznets curve ekc hypothesis states that pollution levels increase as a country develops but begin to decrease as rising incomes pass beyond a turning point in ekc analyses the relationship between environmental degradation and income is usually expressed as a quadratic function with the turning point occurring at a maximum pollution level other explanatory variables have been included in these models but income regularly has had the most significant effect on indicators of environmental quality one variable consistently omitted in these relationships is the price of energy this paper analyzes previous models to illustrate the importance of prices in these models and then includes prices in an econometric ekc framework testing energy income and co2 income relationships these long run price income models find that income is no longer the most relevant indicator of environmental quality or energy demand indeed we find no significant evidence for the existence of an ekc within the range of current incomes for energy in the presence of price and trade variables

consumer expectation and output growth the case of china abstract this study shows that china s consumer expectation index contains useful information about pure expectation shocks which are unrelated to economic fundamentals it turns out that such shocks are likely to be an important independent driver of industrial output growth

modeling the global relationships among economic growth energy consumption and co2 emissions abstract the relationships among economic growth energy consumption and greenhouse gas emissions needs to be paid attention since the characteristics of global warming is from economy and greenhouse gas emissions this study employs a panel cointegration and vector error correction model to discuss the dynamic economy energy environment nexus for 188 countries for the periods of 1993 2010 the empirical results indicate that there exist long run relationships between economic growth energy consumption and carbon dioxide emissions for all countries it is worth noting that energy consumption negatively affects gdp in the world as a whole and developing countries but not in developed countries and the unidirectional causality from energy consumption to carbon dioxide emissions exists both on developing and developed countries that means the developed countries should take more responsibility on the energy efficiency and mitigating greenhouse gas emissions ghge on other hand environmental regulations related to the prevention of environmental degradation as the economy grows need to be adopted by all countries

co2 emissions energy consumption and economic growth in bric countries abstract this paper examines dynamic causal relationships between pollutant emissions energy consumption and output for a panel of bric countries over the period 1971 2005 except for russia 1990 2005 in long run equilibrium energy consumption has a positive and statistically significant impact on emissions while real output exhibits the inverted u shape pattern associated with the environmental kuznets curve ekc hypothesis with the threshold income of 5 393 in logarithms in the short term changes in emissions are driven mostly by the error correction term and short term energy consumption shocks as opposed to short term output shocks for each country short term deviations from the long term equilibrium take from 0 770 years russia to 5 848 years brazil to correct the panel causality results indicate there are energy consumption emissions bidirectional strong causality and energy consumption output bidirectional long run causality along with unidirectional both strong and short run causalities from emissions and energy consumption respectively to output overall in order to reduce emissions and not to adversely affect economic growth increasing both energy supply investment and energy efficiency and stepping up energy conservation policies to reduce unnecessary wastage of energy can be initiated for energy dependent bric countries

energy investment economic growth and carbon emissions in china empirical analysis based on spatial durbin model abstract the international community has reached a consensus on preventing the global climate from deterioration by stabilizing greenhouse gas concentrations in the atmosphere energy industry is a key field for greenhouse gas emission and investment in the energy industry plays a crucial part in promoting the low carbon development of china s energy industry energy investment can effectively break the high carbon lock in effect of energy industry and achieve the low carbon development of energy industry by guiding regulating and gathering social funds into the field of cleaner production and the field of low carbon technology based on the unified framework of energy economy and environment this article takes 30 provinces in china as the research object and constructs a spatial econometric model to investigate the impact of energy investment and economic growth on carbon emission reduction the results indicate that both energy investment and economic growth are responsible for the increase of china s provincial co2 emissions but their driving mechanisms are significantly different furthermore the increase of carbon emissions in adjacent provinces will bring about the increase of local carbon emissions through spatial spillover effects based on these findings the corresponding countermeasures and policy suggestions are put forward

renewable energy consumption in eu 28 countries policy toward pollution mitigation and economic sustainability abstract a major challenge facing humans in the 21st century is how to strike a balance between the mitigation of environmental degradation and the achievement of sustainable economic growth on this note this investigation applies an autoregressive distributed lag ardl methodology to a panel data of 28 european union eu 28 countries over the period 1995 2015 the study confirms the existence of positive and significant long run nexus among environmental sustainability renewable energy consumption and economic growth in the eu 28 countries in addition empirical results indicate that real gross fixed capital formation carbon emissions and other environmental factors are principal determinants of long run growth in the eu using dumitrescu and hurlin 2012 granger non causality in heterogeneous panel results show long run bidirectional causal relationships among renewable energy consumption economic growth and other growth determinants based on these results we infer that the exploitation of renewable energy sources in the eu 28 countries is a reliable pathway toward environmental pollution mitigation consequently achieving sustainable development goals sdgs by the year 2030 through renewable energy consumption and carbon emission mitigation is very much achievable in the eu 28 countries and should also be adopted by all countries as an effective global policy

between estimates of the emissions income elasticity abstract recent papers by wagner and vollebergh et al point out some fundamental econometric problems with traditional methods of estimating the environmental kuznets curve ekc and propose alternative approaches that avoid these issues wagner notes that traditional methods do not take into account the presence of powers of unit root variables and cross sectional dependence in the data while vollebergh et al point out that the time effects are not uniquely identified in the ekc model the between estimator is a simple estimator that also addresses the concerns of these authors it makes no a priori assumption about the nature of the time effects and is likely to provide consistent estimates of long run relationships in real world data situations i apply several common panel data estimators including the between estimator to oecd and global carbon and sulfur emissions datasets the between estimates of the sulfur income elasticity are 0 732 in the oecd and 1 067 in the global data set and the estimated carbon income elasticity is 1 612 in the oecd and 1 509 globally

testing the environmental kuznets curve hypothesis across the u s evidence from panel mean group estimators abstract it is widely believed that greenhouse gases contribute to a warmer climate since global warming is a serious threat and greenhouse gas emissions are one of the main causes of it analyzing the effects of economic development on environment have great importance in this study the validity of the environmental kuznets curve ekc hypothesis is tested for the 50 u s states during the 1960 2010 period using recent panel data estimators that take cross sectional dependence and slope heterogeneity into account accordingly the cross sectional dependence and slope heterogeneity robust estimators augmented mean group amg and common correlated effects mean group estimator ccemg provide mixed results the amg estimator strongly validates the ekc hypothesis asserting that the ekc holds in 30 of the 50 states with turning points for income per capita lie between 1292 and 48597 on the contrary the ccemg estimator provides only weak evidence on the ekc hypothesis and the ekc holds only in 10 states with turning points between 2457 and 14603

consumer confidence and rational expectations are agents beliefs consistent with the theory consumer confidence is found to have predictive content for a wide range of macroeconomic variables including consumption growth contrary to standard repih we find that on uk data the repih is rejected due to the predictive content of consumer confidence and not labour income we explain this finding in terms of precautionary behaviour extending the hansen and singleton consumption capm model to allow a conditional variance we find a high level of confidence is associated with both greater optimism about the level of consumption and greater uncertainty about the forecaster variance once allowance is made for time aggregation the over identifying restrictions implied by this model are accepted we estimate a small but statistically significant intertemporal elasticity of substitution

confidence and the real economy the japanese case this paper empirically analyses whether consumer confidence has an effect on the real economy in japan this paper uses vector autoregressions including variables which represent consumer confidence it is shown that in the cases of quarterly and monthly data consumer confidence has a significant effect on gdp fluctuations whereas in the case of semiannual data it has no effect in other words consumer confidence has an effect on only short term economic fluctuations

how economic growth affects emissions an investigation of the environmental kuznets curve in portuguese and spanish economic activity sectors abstract it is a disquieting reality that increased economic growth for many years now in the western world is at odds with environmental degradation in this paper the relationship between economic growth and environmental variables is analyzed under two non linear specifications a quadratic and a cubic specification the study is conducted for portugal and spain in the period 1975 2012 using data for 13 sectors gva is used as proxy for income while energy use and carbon dioxide account for environmental degradation there is evidence for an inverted u shaped ekc however there are also other inverted n shaped functions that explain the relationship between economic growth and emissions altogether empirical results do indicate particular differences between portuguese and spanish sectors the results are of interest not only for researchers but also for policy makers political mitigation measures are also analyzed

identifying reduced form relations with panel data the case of pollution and income abstract in this paper we propose a solution to the non robustness that plagues the estimation of inverted u shaped relationships using panel data such as the relation between pollution and income when dependent and independent variable like pollution and income are both time related separating the effect of the independent variable from time effects brings about a fundamental identification dilemma the imposition of restrictions on the controls might drive the shape of the relationship between the dependent pollution and independent income variables our solution consists of imposing the very weak constraint that arbitrary cross sectional units have the same relationship we apply our methodology to two widely studied cases namely so 2 and co 2 emissions interestingly our estimates are insensitive to the required subjective choices but also strongly differ from the literature so far we find consistent positive income effects for both cases and time effect estimates with a clear u shaped trend for so 2 emissions but only slightly so for co 2 emissions

money planning and rural transformation in mozambique this article argues that the transformation of the rural economy should proceed on a broad front which links the development of the state sector with the need to transform family agriculture through co operatisation in actual fact planning became concentrated on the state sector which received the bulk of the investible resources disequilibria between the planned needs of resources and their real availability destabilised the exchange between the state sector and peasant production and consequently blocked the possibilities of transforming family agriculture this contradition expresses itself in the form of monetary disequilibrium but it cannot be solved by monetary policy only rather it requires rethinking the nature of planning itself

economic growth fossil fuel and non fossil consumption a pooled mean group analysis using proxies for capital this study employs a pooled mean group estimator to examine the nexus between economic growth and fossil and non fossil fuel consumption for 53 countries between 1990 and 2012 the global sample was divided into four categories developed exporters developed importers developing exporters and developing importers the purpose of these categories was to observe whether factors unique to these countries influence the relationship between energy consumption and economic growth with the exception of developing importers evidence of bi directional causality between fossil fuel consumption and real gdp across all subsamples is observed this leads to the conclusion that efforts to directly conserve fossil fuels may harm economic growth in terms of non fossil fuel use the results are more diverse bi directional causality between non fossil fuel use and real gdp is found in the long and short run for developed importers bi directional causality only in the long run for developed exporters negative long run causality from real gdp to non fossil fuels for developing exporters and long run causality from non fossil fuel use to real gdp for developing importers these results lead to the conclusion that other factors have been responsible for the progress seen in non fossil fuel use thus it is concluded that economic growth on its own is insufficient to promote clean energy development there is a need for policy makers to create an environment conducive to renewable energy investment

non renewable and renewable energy consumption and co2 emissions in oecd countries a comparative analysis abstract this paper attempts to explore the determinants of co 2 emissions using the stirpat model and data from 1980 to 2011 for oecd countries the empirical results show that non renewable energy consumption increases co 2 emissions whereas renewable energy consumption decreases co 2 emissions further the results support the existence of an environmental kuznets curve between urbanisation and co 2 emissions implying that at higher levels of urbanisation the environmental impact decreases therefore the overall evidence suggests that policy makers should focus on urban planning as well as clean energy development to make substantial contributions to both reducing non renewable energy use and mitigating climate change

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

accumulation social services and socialist transition in the third world reflections on decentralised planning based on the mozambican experience the purpose of this article is to argue for the viability and the logic of a distinctive approach to planning economic development and socialist transition in poor economies the components of this distinctive approach are more decentralised and popularly based planning and control of accumulation the close interlinking of investment in social services and in rural production and an emphasis on intervention in the market as a tool of socialist planning the article therefore presents an argument about economic planning intended to be relevant to a range of countries with similar general aims and problems however the ideas are developed here as they were in practice through a reflection on our own understanding of planning andits problems in mozambique during the first ten years of that country s independence 1

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

explaining the relationship between co2 emissions and national income the role of energy consumption i estimate a simultaneous equation system in which gdp and co2 emissions are jointly determined i find that including energy consumption in the regression implies a negative relationship between income and co2 emissions which is contrary to previous findings

the heterogeneity of carbon kuznets curves for advanced countries comparing homogeneous heterogeneous and shrinkage bayesian estimators we investigate carbon kuznets curves ckc relationships for advanced countries grouped in policy relevant groups north america and oceania south europe north europe by means of various homogeneous heterogeneous and shrinkage bayesian panel estimators we try to provide an answer to the question how sensitive are the ckc estimates to changes in the level of parameters heterogeneity we do find that in coherence with their policy and economic commitment to carbon reductions and environmental market based instruments implementation bell shapes are present only for northern eu which leads the group of advanced countries the other two lag behind we show for the first time that ckc shapes are present if we net out europe of the southern and less developed countries this is coherent with the kuznets paradigm the negative side of the tale is that they characterize a bunch of few countries other advanced countries lag behind and are far from reaching a ckc dynamics heterogeneous and bayesian

carbon dioxide emissions and economic growth an assessment based on production and consumption emission inventories working with a new dataset on comparable global co2 production and consumption inventories spanning the 1997 2011 period we investigate the relationship between real gross domestic product gdp per capita and co2 emissions per capita associated with both production and consumption activities by including linkages between production based emissions in one country and final consumption in another via cross border value chains we focus on the entire carbon chain we estimate polynomial and threshold models accounting for reverse causality and identification problems we find that the income elasticity for both inventories is regime dependent and reflects small carbon efficiency gains from economic development carbon footprints show larger income elasticities while national policy instruments targeting production can clearly be circumvented by carbon embodied in intermediate trade this implies problems of environmental sustainability that may require consumption based policy instruments

finance inequality nexus the long and the short of it financial development affects income inequality differently in the short and in the long term investigating oecd countries from 1870 2011 we find in the short run an improvement in financial development tends to reduce inequality while in the long run more finance contributes to more inequality the short run effect concurs with theories advocating financial development increases the availability of financial services primarily for the poor however this effect becomes nil within a few years results thus imply that policies aimed at reducing inequality through improving access of the poor to finance need to be carefully designed to ensure longevity of impact

environmental kuznets curve in china new evidence from dynamic panel analysis this paper applies a panel of 28 provinces of china from 1996 to 2012 to study the impacts of economic development energy consumption trade openness and urbanization on the carbon dioxide waste water and waste solid emissions by estimating a dynamic panel model with the system generalized method of moments gmm estimator and an autoregressive distributed lag ardl model with alternative panel estimators respectively we find that the environmental kuznets curve ekc hypothesis is well supported for all three major pollutant emissions in china across different models and estimation methods our study also confirms positive effects of energy consumption on various pollutant emissions in addition we find some evidence that trade and urbanization may deteriorate environmental quality in the long run albeit not in the short run from policy perspective our estimation results bode well for chinese government s goal of capping greenhouse emissions by 2030 as outlined in the recent china us climate accord while containing energy consumption and harm effects from expanding trade and urbanization remains some environmental challenges that china faces

south african land policy the legacy of history and current options abstract the highly dualistic farm structure of south africa and the low productivity of native african farmers have been the result of systematic distortions in land allocation output markets the provision of infrastructure agricultural credit and services the dualistic structure did not emerge because of genuine economies of scale in the large commercial sector other countries in latin america and africa that once supported a dualistic farm size structure through similar distortions have either implemented large scale land reforms or have experienced decades of peasant revolts and civil war the paper compares these international experiences to south africa and outlines judicial and market assisted approaches to south african land reform

consumer confidence and economic fluctuations if consumers become pessimistic about the state of the economy can there be a slowdown in output even if their pessimism is not based on economic fundamentals recent macroeconomic models show the answer is yes if there are strategic complementarities and multiple equilibria we investigate the link between consumer confidence and economic fluctuations using vector autoregressions in all models after controlling for economic fundamentals the hypothesis that consumer sentiment does not cause gnp in the granger sense can be rejected variance decompositions suggest that consumer sentiment accounts for between 13 and 26 percent of the innovation variance of gnp

the effect of government expenditure on the environment an empirical investigation abstract this paper examines the impact of government spending on the environment using a panel of 77 countries for the time period 1980 2000 we estimate both the direct and indirect effects of government spending on pollution the indirect effect in particular operates through the impact of government spending on income and the subsequent effect of the income level on pollution to take into account the dynamic nature and the potential endogeneity in the relationships examined appropriate econometric methods are used for so2 government spending is estimated to have a negative direct impact on per capita emissions while the direct effect is insignificant on co2 pollution the indirect effect on so2 is negative for low income levels and becomes positive as income increases while it remains negative for co2 for the most part of the sample range the resultant total effects follow the patterns of the indirect effects which dominate their respective direct ones for each pollutant policy implications from the results vary depending on the income level of the considered countries

does disaggregated co2 emission matter for growth evidence from thirty countries abstract this paper investigates the causal relationship between economic growth and aggregated carbon dioxide co 2 emission as well as economic growth and disaggregated co 2 emission from burning fossil fuel coal oil and natural gas in addition the analysis extends the potential impact on economic growth if countries substitute co 2 emission from dirty energy coal by emission from relatively cleaner energy oil and natural gas the study carries out a panel analysis of 30 countries during 1960 2010 panel unit root tests cointegration techniques and causality tests are used to investigate these relationships using panel var in first differences framework the result indicates that there are feedback relationships in all cases except a unidirectional causality running from economic growth to coal induced co 2 emission utilizing wald test with linear restriction the result also finds that countries will be environmentally benefited if they substitute emission from coal by that of oil and natural gas that is if they substitute coal consumption by oil and natural gas consumption depending on the findings the paper suggests some essential policies

co2 emissions and economic activity heterogeneity across countries and non stationary series this paper explores the relationship between co2 emissions and economic activity for 31 countries 28 oecd brazil china and india during the period 1950 to 2006 using cointegration analysis single country long run relationships are estimated and equality in the functional form the parameters and the turning point when appropriate are rejected this confirms the relevance of considering the differences among countries in the relationship between air pollution and economic activity to avoid wrong estimations and conclusions

the co2 emissions development nexus revisited abstract this study revisited the co2 emissions development nexus for this purpose a comprehensive analysis was performed using recent and extensive datasets and employing three different econometric methods namely the cross sectional regression the cointegrating regression and the threshold regression the findings revealed that an environmental regime transformation had occurred in the relationship between the co2 emission intensity and economic development thus the results indicated that in recent decades the inverted n shaped cubic relationship between these variables transformed into the inverted u shaped quadratic relationship by contrast as far as the relationship between the co2 emission per capita and economic development is concerned the u shaped relationship between the variables remained unchanged in other words the present study has detected the inverted u shaped or the environmental kuznets curve ekc relationship between the co2 emission intensity and economic development however it was unable to validate the ekc relationship between the co2 emission per capita and economic development

modeling the nexus between carbon dioxide emissions and economic growth the effects of economic growth on the environment have received increased attention as global warming and other environmental problems become more serious many empirical studies explain the nexus between carbon dioxide emissions and economic growth with such models as the environmental kuznets curve ekc theory however the assumptions of these models have never received strict verification with a large available data set and therefore may not be appropriate to describe the relationship in this study the nexus is modeled for 67 countries from 1971 to 2010 using a novel symbolic regression method from the experimental results several conclusions as follows could be reached firstly there is no universal model fitting every country and symbolic regression could discover a set of reasonable models for a specific country or region secondly four models including the inverted n shaped m shaped inverted u shaped and monotonically increasing are frequently found without domain experts intervention in these countries whereas the m shaped model has received little attention in previous studies but exhibits promising performance thirdly the relationship is diversified due to the difference of regions and economic development where developed countries generally follow the inverted n shaped and m shaped models to explain the relationship whereas developing countries are more likely to refer to the inverted n shaped inverted u shaped and monotonically increasing models finally several policy suggestions are presented

the environmental kuznets curve and the structural change hypothesis we provide a very simple macroeconomic investigation of the role that structural changes might play in generating inverted u shaped income pollution relationships differently from previous research which mainly focuses on empirical static or general equilibrium models we develop a standard balanced growth path bgp analysis we show that along the bgp equilibrium an inverted u shaped income pollution relationship may occur as a response to structural changes but whether this is the case or not it will crucially depend upon the magnitude of a production externality parameter moreover we show that the negative relationship between income and pollution can only be a transitory phenomenon and in the long run pollution will increase as income rises generating overall an n shaped pattern

decoupling co2 emission and economic growth in china is there consistency in estimation results in analyzing environmental kuznets curve china is one of the highest growth economies in the world and it has experienced a significant rise in energy consumption and greenhouse gas emissions in recent decades its economic growth heavily depends on fossil fuels of coal and oil which led to huge amount of greenhouse gas emissions this study logically analyzes the nexus of co2 emissions economic growth and energy consumption by decoupling greenhouse gas emission of co2 and economic growth to provide more conclusive evidence on the phenomenon of the environmental kuznets curve ekc over the period 1970 2015 to achieve the objective of consistency in the estimation results the study applies different estimation techniques such as ardl auto regressive distributed lag model fmols fully modified ordinary least squares dols dynamic ordinary least squares and impulse response and variance decomposition in addition the business as usual inverted u shaped relationship between gdp per capita and an economy related co2 emission is hypothesized the result supports the environmental kuznets curve ekc hypothesis from different techniques the turning point hovers around 744665 the estimation result indicates that china ekc turning point shows some inconsistencies when compared to other turning points obtained from different studies the inconsistency of the ekc turning point is attributed to the sensitivity of the result to different data source variables selection different pollutants and scope of the data although the ekc turning point of this present research differs from other china ekc turning points it gives a clear policy roadmap on the pursuance of long run economic growth in favour of environmental quality besides significance of the turning point lies with the need to explore other structural policies such as articulated demographic and energy policies rather than passively waiting for the arrival of the inflexion point one interesting findings of the analysis is the consistency of the estimation results from the different estimation techniques

exploring the relationship between energy usage segregation and environmental degradation in n 11 countries numerous studies regarding the economic growth environmental pollution link have struggled to determine the effects of various forms of energy consumption on environmental degradation particularly in the context of emerging economies this study examines the environmental kuznets curve ekc for co2 emissions in n 11 countries during 1990 2014 by segregating three forms of energy consumption renewable biomass and non renewable urbanization and trade openness are additional explanatory variables that are used in the empirical framework using the generalized moments method gmm the empirical evidence confirms the presence of an n shaped relationship between economic growth and environmental degradation for n 11 countries this study analyzed the interaction effects among trade openness biomass consumption and economic growth these interactions had a negative impact on co2 emissions levels of n 11 countries suitable policy recommendations have been provided based on the detailed results

pooled mean group estimation of an environmental kuznets curve for co2 abstract we apply the pooled mean group estimator to test for the existence of an environmental kuznets curve for co2 in 22 oecd countries this approach allows for more flexible assumptions in a panel data framework the period goes from 1975 to 1998

markets markets everywhere understanding the cuban anomaly abstract cuba has made exceptionally little use of markets compared with other centrally planned economies only in the 1970s did the cubans begin to experiment with a state controlled parallel market and in 1980 with a free peasant market six years into the experiment this market was closed as it produced tensions common to other socialist experiences with market mechanisms high prices growing income and consumption inequality and the illegal redirection of resources from the planned to market sphere the free market was replaced with a more limited market mechanism an expanded parallel market in both agricultural procurement and food distribution considered more compatible with the cuban commitment to egalitarianism

the causal factors of international inequality in hbox co _ 2 emissions per capita a regression based inequality decomposition analysis this paper uses the possibilities provided by the regression based inequality decomposition fields in res labor econ 22 1 38 2003 to explore the contribution of different explanatory factors to international inequality in hbox co 2 emissions per capita in contrast to previous emissions inequality decompositions which were based on identity relationships this methodology does not impose any a priori specific relationship thus it allows an assessment of the contribution to inequality of different relevant variables in short the paper appraises the relative contributions of affluence sectoral composition demographic factors and climate the analysis is applied to selected years of the period 1993 2007 the results show the important though decreasing share of the contribution of demographic factors as well as a significant contribution of affluence and sectoral composition

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

the balance of payments constrained growth rate and the natural rate of growth new empirical evidence this paper implements a panel approach to investigate the empirical relevance of thirlwall s law which states that long run growth must be consistent with balance of payments bop equilibrium and is thus determined on the demand side building on ardl modelling mean group and pooled mean group estimation methods we use annual data over the 1960 2010 years for a panel of 22 oecd countries and find significant support for the law next we also explore empirically the hypothesis that the bop constrained growth rate yb must equal the natural or potential rate of growth yn and find that the data do not reject this hypothesis finally we adopt a new approach based on panel granger causality methods to explore the direction of causality between yb and yn the results indicate the existence of unidirectional long run causality from yb to yn thus reinforcing the view embodied in the law that long run growth is demand determined and constrained by the bop
