wage determination in the uk this paper offers a sysnthesis of a number of important complementary theories of wage determination the model is estimated and tested with respect to its long run and dynamic properties applying johansen s 1998 fiml estimation procedure the maximum eigenvalue and the trace tests suggested two cointegrating vectors and estimated and another the underlying theoritical model we combined both vectors and estimated in a second step an error correction model which was satisfactory with regard to its in sample and out of sample performance none of the assumptions for ols estimation were violated and the recursive estimation revealed model stability additionally the forecasting ability of the model was satisfactory the main feauture of this model is that conflict elements are of parmount in the uk wage determination

the relationship between gdp and electricity consumption in 10 asian countries the purpose of this study is to estimate the relationships between gdp and electricity consumption in 10 newly industrializing and developing asian countries using both single data sets and panel data procedures the empirical results from single data set indicate that the causality directions in the 10 asian countries are mixed while there is a uni directional short run causality running from economic growth to electricity consumption and a bi directional long run causality between electricity consumption and economic growth if the panel data procedure is implemented these empirical findings imply that electricity conservation policies through both rationalizing the electricity supply efficiency improvement to avoid the wastage of electricity and managing demand side to reduce the electricity consumption without affecting the end user benefits could be initiated without adverse effect on economic growth the findings on the long run relationship indicate that a sufficiently large supply of electricity can ensure that a higher level of economic growth

investment the current account and the relative price of non traded goods in a small open economy abstract this paper incorporates traded and non traded investment expenditure into an infinite horizon setting with optimizing economic agents extending previous research that has incorporated traded and non traded investment into a two period setting the paper analyzes the dynamic adjustment of the relative price of non traded output the market price of capital and the current account following exogenous shocks to the system the exogenous shocks considered by the paper include permanent transitory and anticipated changes in an income tax and an investment subsidy as well as changes in the level of government purchases of traded and non traded output

environmental pollution hydropower energy consumption and economic growth evidence from g7 countries abstract the aim of this study is to examine the relationship among environmental pollution economic growth and hydropower energy consumption in the different regimes of the business cycles for g7 countries over the period of 1961 2013 we used markov switching vector autoregressive ms var and ms granger causality methods to achieve this goal since the traditional methods examine the causality by assuming all period in the same level unlike traditional methods these methods allow for determining the relationship and casual dynamics between variables in different regimes the causality results obtained for different regimes assisted to suggest policy recommendations for each regime individually according to analysis results it was found that there is bidirectional granger causality between carbon dioxide emissions and economic growth in the crisis regime and in the high growth regime while carbon dioxide emissions are granger cause of economic growth in all regimes in general we found evidence that hydropower energy consumption is granger cause of economic growth in general whereas there is a bidirectional causality for some g7 countries furthermore the results from these models indicate that in the first second and third regimes carbon dioxide emissions are granger cause of hydropower energy consumption and hydropower energy consumption is granger cause of carbon dioxide emissions for some g7 countries

the role of energy in real business cycle models abstract this paper modifies hansen s 1985 analysis of a real business cycle mode with indivisible labor by explicitly including energy as a productive input and modelling the relative price of energy as an exogenous random process one goal is to determine the extent to which the introduction of energy price shocks reduces the reliance of the real business cycle model on unobserved technology shocks the other goal following christiano and eichenbaum 1991 is to compare the correlation between real wages and hours predicted by the energy inclusive model to that predicted by hansen s model

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

modeling the causal linkages between nuclear energy renewable energy and economic growth in developed and developing countries abstract this article investigates the causal relationship between two types of energy variables and economic growth using dynamic simultaneous equation panel data models for 17 developed and developing countries our results indicate that there is a unidirectional causality running from nuclear consumption to economic growth in belgium and spain while a unidirectional causality running from economic growth to nuclear consumption is supported in bulgaria canada netherlands and sweden a bidirectional relationship appears in argentina brazil france pakistan and the usa while no causality exists in finland hungary india japan switzerland and the u k second the results for the second nexus among renewable energy and economic growth show that there is a unidirectional causality running from renewable consumption to economic growth in hungary india japan netherlands and sweden while there exist a unidirectional running from economic growth to renewable consumption in argentina spain and switzerland a bidirectional relationship is supported in belgium bulgaria canada france pakistan and the usa while no causality exists in brazil finland and switzerland third we find the existence of a bidirectional causality between nuclear consumption and economic and a unidirectional causality running from economic growth to renewable energy consumption for the global panel

the terms of trade and the current account the harberger laursen metzler effect the paper examines the effect of terms of trade changes on a small country s spending and current account assuming optimizing behavior in an intertemporal framework with perfect international capital mobility a temporary future terms of trade deterioration implies a deterioration improvement of the trade balance whereas a permanent terms of trade deterioration has an ambiguous effect depending on the rate of time preference nominal and real variables are considered via exact price indexes two periods and an infinite horizon are examined

a note on the electricity growth nexus in lao pdr abstract this paper investigates the relationship between electricity consumption and economic growth in laos by applying the ardl bounds testing approach to cointegration and granger causality tests our results confirm the existence of a long run relationship between electricity consumption and economic growth in addition we found unidirectional causality running from economic growth to electricity consumption in the long run supporting the conservation hypothesis

the impact of oil prices on gdp in european countries an empirical investigation based on asymmetric cointegration this paper investigates the existence of a long term relationship between oil prices and gdp in 12 european countries to account for the fact that economic activity responds asymmetrically to oil price shocks we propose an approach based on asymmetric cointegration our results show that while standard cointegration is rejected there is evidence for asymmetric cointegration between oil prices and gdp in the majority of the considered european countries

output renewable energy consumption and trade in africa abstract we use panel cointegration techniques to examine the relationship between renewable energy consumption trade and output in a sample of 11 african countries covering the period 1980 2008 the results from panel error correction model reveal that there is evidence of a bidirectional causality between output and exports and between output and imports in both the short and long run however in the short run there is no evidence of causality between output and renewable energy consumption and between trade exports or imports and renewable energy consumption also in the long run there is no causality running from output or trade to renewable energy in the long run our estimations show that renewable energy consumption and trade have a statistically significant and positive impact on output our energy policy recommendations are that national authorities should design appropriate fiscal incentives to encourage the use of renewable energies create more regional economic integration for renewable energy technologies and encourage trade openness because of its positive impact on technology transfer and on output

testing for the cointegrating rank of a var process with structural shifts tests for the cointegrating rank of a vector autoregressive process are considered that allow for possible exogenous shifts in the mean of the data generation process the break points are assumed to be known a priori it is proposed to estimate and remove the deterministic terms such as mean linear trend term and a shift in a first step then systems cointegration tests are applied to the adjusted series the resulting tests are shown to have known limiting null distributions that are free of nuisance parameters and do not depend on the break point the tests are applied for analyzing the number of cointegrating relations in two german money demand systems

the employment and wage effects of oil price changes a sectoral analysis in this paper we use micro panel data to examine the effects of oil price changes on employment and real wages at the aggregate and industry levels we also measure differences in the employment and wage responses for workers differentiated on the basis of skill level we find that oil price increases result in a substantial decline in real wages for all workers but raise the relative wage of skilled workers the use of panel data econometric techniques to control for unobserved heterogeneity is essential to uncover this result which is completely hidden in ols estimates while the short run effect of an oil price increase on aggregate employment is negative the long run effect is in fact positive we find that changes in oil prices induce changes in employment shares and relative wages across industries however we find little evidence that oil price changes cause labor to consistently flow into those sectors with relative wage increases copyright 1996 by mit press

will initiatives to promote hydroelectricity consumption be effective evidence from univariate and panel lm unit root tests with structural breaks abstract this paper examines whether initiatives to promote hydroelectricity consumption are likely to be effective by applying univariate and panel lagrange multiplier lm unit root tests to hydroelectricity consumption in 55 countries over the period 1965 2011 we find that for the panel as well as about four fifths of individual countries that hydroelectricity consumption is stationary this result implies that shocks to hydroelectricity consumption in most countries will only result in temporary deviations from the long run growth path an important consequence of this finding is that initiatives designed to have permanent positive effects on hydroelectricity consumption such as large scale dam construction are unlikely to be effective in increasing the share of hydroelectricity relative to consumption of fossil fuels

tariffs and the current account abstract this paper examines the impact of a tariff on the current account in a model which emphasizes the fact that it takes time for the production sector of an economy to adjust to a change in relative prices income effects of the adjustment lead to a transitory current account surplus because the deleterious effect of the tariff on national income is larger in the long run than in the short run in addition relative prices overshoot in response to the tariff leading to an increase in the consumption rate of interest which in turn generates an increase in desired saving

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

can biomass energy be an efficient policy tool for sustainable development abstract this paper first reviews the potential causality from biomass energy to co2 emissions and economic development within relevant literature later the paper examines statistically the impacts of biomass energy consumption on co2 emissions and gdp in the us to this end paper observes environmental and economic implications of biomass fuel usage throughout energy literature and launches asymmetric causality test to confirm disconfirm the literature output the findings of the tests indicate that biomass energy consumption per capita mitigates co2 emissions per capita and increases gdp per capita eventually upon its output this research asserts that biomass energy consumption can be an efficient policy tool for environmentally sustainable development in the us and that hence biomass production technologies and biomass consumption need to be promoted in other countries as well as in the us on the other hand analyses underline the fact that policy makers should consider as well some potential constraints of biomass energy usage such as land use constraints and carbon leakage from biomass production therefore although this paper explores the remedial impact of biomass on environment and growth one may suggest also that further possible works consider the effects of biomass sources in detail to minimize the some worsening influence of biomass usage on climate change

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

asymmetric oil shocks and external balances of major oil exporting and importing countries this study investigates the effects of oil price shocks on three measures of oil exporters and oil importers external balances total trade balance oil trade balance and non oil trade balance we employ three second generation heterogeneous linear panel models and one recently developed non linear panel estimation technique that allows for cross sectional dependence with respect to 28 major oil exporting countries an increase in oil prices leads to an improved real oil trade balance although it is detrimental to non oil and total trade balances this finding might be due to the expenditure effect arising from increases in proceeds from oil exports a decrease in oil prices is found to be beneficial for both total and oil trade balances in these oil exporting countries forty major oil importers seem to be increasingly shielded from positive oil shocks over the 1970s and 1980s however they must worry about oil price declines a decline in oil prices has a negative impact on both total and real oil trade balances resulting from increased oil imports in emerging economies hence a decline in oil prices is beneficial to oil exporters due to the quantity effect outweighing the price effect while for oil importers a stable oil price is more desirable than a price decline these results are important to take into account if we are to gain a full understanding on the magnitude of the trade and macroeconomic effects of oil price changes and what the policy responses should be

the macroeconomic strike model a study of seventeen countries 1948 1975 this paper reports the results of an analysis of data on industrial conflict strikes and lockouts in seventeen oecd countries during the period 1948 75 a number of models are tested on this broad data set including the major elements of the ashenfelter and johnson model contrary to ashenfelter and johnson s results for the united states this study finds for most countries a positive relationship between the number of conflicts and the rate of increase in real wages in manufacturing further the increase in nominal wages produces stronger results in all models tested than the increase in real wages the effect of unemployment is unstable across countries and only one of two political variables yields even modest results the authors suggest that an explanation of their findings might be found in the relationship between changes in the wage structure and changes in the level of conflict

sustainable design of renewable energy supply chains integrated with district heating systems a fuzzy optimization approach abstract this study aims to develop a comprehensive decision model for sustainable design of biomass based renewable energy supply chains and district heating systems dhs with thermal energy storages the model integrates the strategic decisions such as location and capacity selection for energy plants dhs thermal storages and biomass storages with tactical decisions related to biomass production supply and transportation planning inventory management and energy production the main purpose is to find the optimum configuration of the supply chain and dhs to meet the heat demand of a particular locality the model combines cost and service level objectives and accounts for biomass supply material flow capacity demand and technical constraints the problem is formulated as a fuzzy mixed integer linear programming milp model that comprises multiple biomass types and system uncertainties to explore the viability of the proposed model computational experiments are performed on a real world case sensitivity analyses are conducted to examine the impacts of cost and capacity limit of thermal energy storage as well as heat demand on the objective functions and thermal storage capacity the results reveal that the proposed model can effectively be used in practice to assist the decision makers in planning energy production systems in a sustainable and effective manner

oil prices inflation and interest rates in a structural cointegrated var model for the g 7 countries sharp increases in the price of oil are generally seen as a major contributor to business cycle asymmetries moreover the very recent highs registered in the world oil market are causing concern about possible slowdowns in the economic performance of the most developed countries in this paper a structural cointegrated var model has been considered for the g 7 countries in order to study the direct effects of oil price shocks on output and prices and the reaction of monetary variables to external shocks our results can be summarized as follows i a stationary money demand as suggested by the classic theory of money can be identified for most countries ii according to the estimated coefficients of the structural part of the model for all countries except japan and u k the null hypothesis of an influence of oil prices on the inflation rate cannot be rejected inflation rate shocks are transmitted to the real economy by increasing interest rates iii impulse response analysis suggests for most countries the existence of an instantaneous temporary effect of oil price innovations on prices iv impulse response functions indicate different monetary policy reactions to inflationary and growth shocks v the simulation exercises directed to estimate the total impact of the 1990 oil price shock indicate that for some countries u s a significant part of the effects of the oil price shock is due to the monetary policy reaction function for other countries canada france and italy however the total impact is offset at least in part by an easing of monetary conditions

asymmetric effects of oil price changes on the balance of trade evidence from selected african countries the main new contribution of this study was to delve into the asymmetric impacts of changes in oil prices on the trade balance in the framework of six major african economies to tackle this topic carefully we employ three measures of external balances oil non oil and total trade balances and assess the asymmetric response of the external balances of those six economies to oil price changes in the short and long run like most previous studies we first assume the impacts of oil price fluctuations to be symmetric and employ the linear autoregressive distributed lag ardl method to explore the topic we then separate oil price hikes from oil price plunges and implement the non linear ardl method to reveal that the price of crude oil has a vital role to play in the trade balances for those six african economies further there is evidence of significant asymmetric impacts of oil prices typically on the oil trade balance of africa s top oil producing countries for the non oil and total trade balances in contrast there is little evidence of the asymmetry of oil price changes

energy and resource allocation a dynamic model of the dutch disease it is well known that a domestic resource discovery gives rise to wealth effects that cause a squeeze of the tradeable good sector of an open economy the decline of the manufacturing sector following an energy discovery has been termed the dutch disease and has been investigated in many recent studies our model extends the principally static analyses to date by allowing for 1 short run capital specificity and long run capital mobility 2 international capital flows and 3 far sighted intertemporal optimizing behaviour by households and firms the model is solved by numerical simulation

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

oil prices and the terms of trade abstract the combination of substantial terms of trade variability and unstable correlation patterns of trade prices with output and trade volumes has led some to suggest a break in the link between trade volumes and prices we find that oil accounts for much of the variation in the terms of trade over the last twenty five years and its quantitative role varies significantly over time and since our dynamic general equilibrium model predicts that the economy responds differently to oil supply shocks than to other shocks changes in their relative importance helps to account for the unstable correlations in the data

oil price shocks and the dispersion hypothesis recent research by david lilien shows that a significant fraction of aggregate unemployment can be explained by the dispersion of employment growth across industries this paper presents two new results in this area first it is shown that a significant fraction of the variation in lilien s dispersion index is due to the differential impact of oil shocks across industries second and more important it is shown that once the dispersion in employment growth due to oil shocks is accounted for the residual dispersion has no explanatory power for unemployment

a novel closed loop supply chain based on the quality of returned products abstract closing an existing real world supply chain and modelling the resultant network are challenging practices this paper investigates the possibility of closing the chain in a textile company and the effects of such a decision on the profits of the chain the paper addresses one of the common problems in modelling the return rates of backward chain since inaccuracy in estimation of such rates leads to incorrect results the present model forgoes the need for commonly used predetermined rates by proposing a conditional quality based segmentation policy addition of a secondary chain as a recovery option quality dependent incentive rates and flexibility of the model in defining quality are also among novel points of this paper first a bi objective model is proposed to formulate the chain which includes the manufacturers distributors and customers in the forward chain and remanufacturing repairing and recycling centers in the backward chain this model is applicable to industries with zero waste strategy and similar recovery facilities second an extensive sensitivity analysis is carried out on a case study from textile industry the results reveal that increase in rate of returns with low medium qualities leads to higher profits since they create more suitable environmental economical business opportunities moreover closing the supply chain of the company increases the impact of distributors collectors performance on the final profits hence managers of the company need to adopt a pricing policy in favor of the distributors collectors which equals to lower repairing remanufacturing and purchase costs from manufacturers and higher sales prices to customers manufacturers and recycling center

a robust fuzzy optimization model for carbon efficient closed loop supply chain network design problem a numerical illustration in electronics industry abstract environmentalism has become an important global issue in the present century during the recent years the closed loop green supply chain management has been increasingly a center of attention as a result of governmental laws and legislations regarding the environmental effects of any activity and the soaring consumers expectations in this study effort has been made to investigate a facility location allocation model for a multi product closed loop green supply chain network consisting of manufacturing remanufacturing and collection inspection centers as well as disposal center and markets to design the network we have proposed a mixed integer linear programming model capable of reducing the network total costs the model has been so developed as to consider such environmental objectives as reducing the rate of carbon dioxide emission in the environment throughout the network in question moreover the model has been developed using a robust fuzzy programming approach to investigate the effects of uncertainties of the variable costs as well as the demand rate on the network design to solve the bi objective programming model use has been made of the e constraint approach and a numerical illustration of copiers industry is used to show the applicability of the proposed optimization model results have revealed that the model is capable of controlling the network uncertainties as a result of which a robustness price will be imposed on the system

the effect of urbanization on co2 emissions in emerging economies the theories of ecological modernization and urban environmental transition both recognize that urbanization can have positive and negative impacts on the natural environment with the net effect being hard to determine a priori this study uses recently developed panel regression techniques that allow for heterogeneous slope coefficients and cross section dependence to model the impact that urbanization has on co2 emissions for a panel of emerging economies the estimated contemporaneous coefficients on the energy intensity and affluence variables are positive statistically significant and fairly similar across different estimation techniques by comparison the estimated contemporaneous coefficient on the urbanization variable is sensitive to the estimation technique in most specifications the estimated coefficient on the urbanization variable is positive but statistically insignificant the implications of these results for sustainable development policy are discussed

on the causal dynamics between economic growth renewable energy consumption co2 emissions and trade openness fresh evidence from brics countries abstract the current study investigates the causal relationship between economic growth and renewable energy consumption in the brics countries over the period 1971 2010 within a multivariate framework the ardl bounds testing approach to cointegration and vector error correction model vecm are used to examine the long run and causal relationships between economic growth renewable energy consumption trade openness and carbon dioxide emissions empirical evidence shows that based on the ardl estimates there exist long run equilibrium relationships among the competing variables regarding the vecm results bi directional granger causality exists between economic growth and renewable energy consumption suggesting the feedback hypothesis which can explain the role of renewable energy in stimulating economic growth in brics countries

a neoclassical model of unemployment and the business cycle this paper investigates a general equilibrium model of unemployment and the business cycle in which specialization of labor plays a key role a rational expectations equilibrium with fully flexible wages and prices can exhibit unemployment in which the marginal product of employed workers exceeds the reservation wage of those who are without jobs workers are unemployed either because they are in the process of relocating for a better job or because they are waiting for conditions in the depressed sector to improve moreover seemingly small disruptions in the supplies of primary commodities such as energy could be the source of fluctuations in aggregate employment and can exert surprisingly large effects on real output

use renewables to be cleaner meta analysis of the renewable energy consumption economic growth nexus abstract the renewable energy consumption economic growth nexus is a growing area of research over the last few years emanating to mixed results the aim of the current study is to quantitatively synthesise the empirical literature on the subject using the meta analysis approach in particular a meta multinomial regression is employed to investigate the sources of variation in the direction of causality between renewable energy consumption and economic growth this causal relationship takes the form of four hypotheses namely the feedback conservation growth and neutrality hypotheses to the best of author s knowledge this study constitutes the first meta analysis undertaken on the renewable energy consumption economic growth nexus the empirical results reveal that the variation in the supported hypotheses is due to a number of characteristics including model specification data characteristics estimation techniques cointegration methods and causality tests and development level of the country on which a study was conducted

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

this is what happened to the oil price macroeconomy relationship abstract many of the quarterly oil price increases observed since 1985 are corrections to even bigger oil price decreases the previous quarter when one looks at the net increase in oil prices over the year recent data are consistent with the historical correlation between oil shocks and recessions

trade linkages and macroeconomic effects of the price of oil in this paper we assess the impact of oil price shocks on oil producer and oil consuming economies var models for different countries are linked together via a trade matrix as in abeysinghe 2001 as expected we find that oil producers here russia and canada benefit from oil price shocks for example a large oil shock leading to a price increase of 50 boosts russian gdp by about 6 however oil producers are hurt by indirect effects of positive oil price shocks as economic activity in their exporter countries suffers for oil consumers the effects are more diverse in some countries output falls in response to an oil price shock while other countries seem to be relatively immune to oil price changes finally indirect effects are also detected for oil consumer countries those countries which trade more with oil producers gain indirect benefits via higher demand from oil producing countries in general the largest negative total effects from positive oil price shocks are found for japan china the usa finland and switzerland while other countries in our sample seem to have fared quite well during recent positive oil price shocks the indirect effects are negative for russia finland germany and netherlands

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

the causal link between energy and output growth evidence from markov switching granger causality abstract in this paper we empirically investigate the causal link between energy consumption and economic growth employing a markov switching granger causality analysis we carry out our investigation using annual u s real gdp total final energy consumption and total primary energy consumption data which cover the period between 1968 and 2010 we find that there are significant changes in the causal relation between energy consumption and economic growth over the sample period under investigation our results show that total final energy consumption and total primary energy consumption have significant predictive content for real economic activity in the u s economy furthermore the causality running from energy consumption to output growth seems to be strongly apparent particularly during the periods of economic downturn and energy crisis we also document that output growth has predictive power in explaining total energy consumption furthermore the power of output growth in predicting total energy consumption is found to diminish after the mid of 1980s

asymmetric oil prices and trade imbalances does the source of the oil shock matter abstract we examine the asymmetric effects of oil supply shocks shocks to global real economic activity and oil specific demand shocks on the oil non oil and overall trade balances of a large sample of oil exporters and oil importers our empirical strategy accounts for endogenous oil prices heterogeneous parameters and error cross section dependence within a panel framework we find that the pattern of asymmetries in the oil price trade balance relationship depends on the source of the shock for both oil exporters and oil importers oil supply expansions are more important than oil supply disruptions we discuss the role that saudi arabia plays in limiting the global effects of oil supply disruptions although increases in global demand deteriorate trade balances for oil importers and improve them for oil exporters decreases in global demand have a similar rather than an opposite effect our results corroborate the existing evidence that oil price increases only generate large global imbalances if they result from demand side shocks and we present new evidence that oil price decreases only benefit oil importers if they result from supply side shocks

testing the ekc hypothesis for the top six hydropower energy consuming countries evidence from fourier bootstrap ardl procedure abstract environmental degradation is an important threat to sustainable development economic growth and fossil fuel based energy consumption are main factors causing environmental pollution the use of renewable energy as an alternative for fossil fuels can help to reduce environmental pollution and thus sustainable development can be achieved from this point of view hydropower is the most widely used renewable energy source in several countries however the effects of hydropower energy on the environment are controversial to add a new dimension to the discussion this study investigates the relationship between hydropower energy consumption ecological footprint and economic growth for the top six hydropower consuming countries within the framework of the environmental kuznets curve ekc hypothesis the study employs newly developed cointegration and causality tests with smooth structural changes over the period 1965 2016 the findings of the fourier bootstrap ardl procedure demonstrate that no cointegration exist between the variables therefore the ekc hypothesis is not valid for brazil china canada india norway and the us furthermore the findings of the fourier toda yamamoto causality test suggest unidirectional causality running from hydropower energy consumption to economic growth in brazil and bidirectional causality between these variables in china in the case of the top six hydropower consuming countries no evidence was found for a causal relationship between hydropower energy and ecological footprint overall these results are important for policy makers hydropower energy plays a crucial role in china and brazil s economic growth policies on the other hand hydropower energy consumption and economic growth do not have a role in mitigating the ecological footprint in six countries for this reason different types of renewable energy consumption should be taken into consideration by countries for the solution of environmental problems

renewable energy and growth evidence from heterogeneous panel of g7 countries using granger causality abstract in this paper we examine the causal relationship between renewable energy consumption and economic growth across the g7 countries using annual data for the period of 1990 2011 by employing the causality methodology proposed by emirmahmutoglu and kose 2011 8 we investigate if there is a causal relationship between the variables the advantage of this methodology is that it takes into account possible slope heterogeneity and cross sectional dependency in a multivariate panel the empirical results support the existence of a bi directional causal relationship between economic growth and renewable energy for the overall panel however looking at the individual results for each country the neutrality hypothesis is confirmed for canada italy and the us while for france and uk there is a unidirectional causality from gdp to renewable energy and the opposite for germany and japan

latin american hydropower a century of uneven evolution abstract latin america is home to a number of the largest countries powered by hydroelectricity in the world today both in absolute and per capita levels this region accounts for over 20 per cent of the world s hydropower and has by far the largest share of hydroelectricity over total electricity generation in the world excluding china latin american hydropower exhibits the fastest growth in the world over the last 30 years despite these records latin america s large hydroelectric potential began to be realised late in comparison to most advanced countries and its advance has been notably uneven across time and space this article provides a succinct survey of the evolution of hydropower for 20 latin american countries over the past century and offers a unique quantitative comparative perspective into the past and present of hydroelectricity in the region we investigate the role played by the different domestic energy endowments in the way hydroelectricity developed across the region we conclude that the gross theoretical hydroelectric potential is a necessary but not sufficient condition for understanding the historical evolution of hydroelectricity in different countries we used panel data analysis to examine the role of alternative sources of energy electric demand and each nation s capacity to supply electricity infrastructure our model explicitly accounts for the effects of different gross theoretical potentials and the effect of time passage overall we report that latin american hydropower followed an uneven path over the 20th century

natural gas consumption and economic growth the role of foreign direct investment capital formation and trade openness in malaysia the objective of this paper is to reinvestigate the relationship between natural gas consumption and economic growth by including foreign direct investment capital and trade openness in malaysia for the period of 1971 2012 the structural break unit root test is employed to investigate the stationary properties of the series we have applied combined cointegration test to examine the relationship between the variables in the long run for robustness sake the ardl bounds testing method is also employed to test for a possible long run relationship in the presence of structural breaks we note the validity of cointegration between the variables natural gas consumption foreign direct investment capital formation and trade openness have positive influence on economic growth in malaysia the results support the presence of feedback hypothesis between natural gas consumption and economic growth foreign direct investment and economic growth and natural gas consumption and foreign direct investment the policy implications of these results are provided

inflation and economic growth in an open developing country the case of brazil this articles studies the relationship between inflation and gdp growth after trade and financial liberalisation in brazil the aim is to provide an explanation for the inverse relationship between economic growth and inflation verified in this economy in the considered period tradeable and non tradeable inflation experiences are studied separately for this purpose the article suggests a model for the relationship between inflation and economic growth under the cost based price approach the model is estimated for the case of brazil confirming the relationships postulated in the article

oil price shocks and real gdp growth empirical evidence for some oecd countries this study assesses empirically the effects of oil price shocks on the real economic activity of the main industrialized countries multivariate var analysis is carried out using both linear and non linear models the latter category includes three approaches employed in the literature namely the asymmetric scaled and net specifications evidence of a non linear impact of oil prices on real gdp is found in particular oil price increases are found to have an impact on gdp growth of a larger magnitude than that of oil price declines with the latter being statistically insignificant in most cases among oil importing countries oil price increases are found to have a negative impact on economic activity in all cases but japan moreover the effect of oil shocks on gdp growth differs between the two oil exporting countries in the sample with the uk being negatively affected by an oil price increase and norway benefiting from it

oil shocks and external balances abstract we provide estimates of the effects of demand and supply shocks in the global crude oil market on several measures of oil exporters and oil importers external balances including the oil trade balance the non oil trade balance the current account capital gains and changes in net foreign assets nfa first we show that the effect of oil demand and supply shocks on the merchandise trade balance and the current account which depending on the source of the shock can be large depends critically on the response of the non oil trade balance our results provide evidence of an intermediate degree of international financial integration second we document the presence of large and systematic valuation effects in response to these shocks valuation effects overall tend to cushion the effect of oil demand and supply shocks on the nfa positions of oil exporters and oil importers third we quantify the overall importance of global business cycle demand shocks as well as oil market specific demand and supply shocks for external balances

oil price shocks and trade imbalances abstract this study aims to examine whether a large part of the variability of trade balances and their oil and non oil components is associated with oil price fluctuations the long run causality running from oil price to overall oil and non oil trade balances and their short run dynamics are investigated by applying the toda and yamamoto 1995 ty causality approach and generalized impulse response functions irfs respectively to the monthly data spanning from january 1999 to november 2011 three asian economies that represent three distinct characteristics in terms of oil are chosen and examined malaysia as an oil exporter singapore as an oil refinery and japan as an oil importer the stability of the causality is also checked and the estimated impulse responses across different periods are examined the results have implications for both policy makers and economic modeling of the impact of oil price shocks

wage determiniation in the uk further empirical results using conintegraion the present paper examines the long run behaviour of two types of wage models for the uk over the preiod 1996 1 1989 2 these models differing in their theoretical construction are estimated and explored using various tests for cointegration the hall 1986 1989 model is based on saragan s 1964 wage specification while the arestis and skott 1993 and arestis and biefang frisancho mariscal 1993 model is concerned with distributional and wage efficeincy theortical effects both models exhibit at least one economically sensible long run relationship for wage determination with significant and correctly signed parameters and show expected proportionality between wages and productivity further the arestis and skott 1993 model shows the effects of effciency wage elements on effort

crude oil and the macroeconomy tests of some popular notions a note perhaps no other economic events in the post world war ii era have generated as much attention as the series of crude oil price shocks that have jolted the world economy since the opec boycott of 1973 a tremendous amount of space in the popular and professional literature has been devoted to analyzing the impacts of these shocks on the developed economies and the adjustments these shocks have induced one residual of this literature has been a general impression that since 1973 the functional relationship between crude oil prices and the developed macroeconomies has been dramatically and fundamentally altered yet to our knowledge no one has formally tested this impression recent evidence of hamilton 1983 suggests that crude oil prices had a strong impact on the u s business cycle well before 1973 further while textbook treatments of oil price shocks tend to highlight cost push inflationary effects the research of berndt and wood 1975 1979 and wilcox 1983 indicates the net complementarity between energy and capital in the u s economy is quite strong both before and after 1973 thus oil price shocks may have stronger real effects than generally believed in this paper we formally test three popular notions associated with the so called

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

are shocks to renewable energy consumption permanent or transitory an empirical investigation for brazil china and india abstract this paper investigates whether there is a unit root in renewable energy consumption in three large developing economies brazil china and india over the period 1971 2014 to do so it uses four unit root tests assuming one structural break two structural breaks and more than two structural breaks it observes that renewable energy consumption is a unit root process in brazil but it is found as stationary in china and india the paper also tackles issues and challenges in the unit root test methodology in energy economics literature and provides implications for renewable energy consumption in three economies

income effects of adjustment to a terms of trade disturbance and the demand for adjustment finance abstract this paper shows that when economic adjustment is costly and therefore takes place gradually it is optimal to seek external finance in response to permanent as well as transitory shocks while at the same time adjusting to the disturbance sluggish adjustment also creates an asymmetric relationship between permanent changes in the terms of trade and optimal foreign borrowing that is while a permanent deterioration in the terms of trade generates a demand for foreign loans so would an improvement the paper presents suggestive evidence that the effects may be empirically significant though they arise from effects that are technically second order of magnitude

renewable and non renewable energy consumption and economic activities further evidence from oecd countries this article examines the dynamic relationship between renewable and non renewable energy consumption and industrial output and gdp growth in oecd countries using data over the period of 1980 2011 the panel cointegration technique allowing structural breaks is used for empirical investigation the results show that there is a long term equilibrium relationship among non renewable and renewable energy sources industrial output and economic growth the panel causality analyses show bidirectional causality between industrial output and both renewable and non renewable energy consumption in the short and long run however there is evidence of bidirectional short run relationship between gdp growth and non renewable energy consumption while unidirectional causality between gdp growth and renewable energy consumption these results indicate that oecd economies still remain energy dependent for their industrial output as well as overall economic growth however expansion of renewable energy sources is a viable solution for addressing energy security and climate change issues and gradually substituting renewable to non renewable energy sources could enhance a sustainable energy economy

renewable energy consumption and unemployment evidence from a sample of 80 countries and nonlinear estimates this article contributes to the discussion on the dynamic nexus of renewable energy consumption and unemployment by incorporating nonlinear cointegration and causality analysis using a sample of 80 countries spanning the period 1990 2013 and the advanced generation of unit root cointegration and nonlinear granger causality methodological approaches in panel data we obtain mixed results about the impact of renewable energy consumption on unemployment although the total findings document a positive impact of renewable energy consumption on unemployment disaggregated data across specific regions such as asia and latin america highlight the favourable effect on unemployment implying that the effect of renewable energy consumption on jobs creation depends on the cost of adopting renewable energy technologies and energy efficiencies that seem to vary across the regions under investigation

dynamic jumps in global oil price and its impacts on china s bulk commodities abstract this paper investigated the impacts of oil price shocks especially dynamic jumps in its returns on china s bulk commodity markets at both the aggregate and industry levels after setting a zero lower bound to the jump intensity of the arji model we found that dynamic jumps exist in oil price movements moreover under shocks of oil price jumps not only the returns but also the risks of china s bulk commodity markets are affected significantly and the reactions of risks are characterized by overreactions meanwhile by decomposing oil price shocks into expected positive negative and unexpected positive negative components we discovered that the impacts of unexpected shocks are positive and significantly asymmetric at both levels while those of the expected shocks are negative and insignificantly asymmetric at the industry level in addition the volatility clustering of all price movements and the permanent volatility effects on china s bulk commodities are also authenticated by applying the garch family models

estimation of electricity demand function for algeria revisit of time series analysis abstract this paper aims to empirically re examine whether economic growth has effect on electricity consumption for algerian economy we have incorporated urbanization and trade openness in electricity demand function as additional determinants of electricity consumption for the period of 1971 2012 for empirical purpose we have applied the recently developed combined cointegration test proposed by bayer and hanck 2013 and bounds testing approach to cointegration by pesaran et al 2001 for establishing the cointegration between the variables by accommodating structural breaks the results expose that income growth leads to higher electricity demand along with urbanization being another major contributing factor of rising electricity demand in contrast trade openness leads to reduce electricity demand the causal association between the variables is further examined with the application of innovation accounting approach of vector autoregressive var the empirical evidence indicates the presence of the neutral effect between income growth and electricity use urbanization causes electricity use and electricity use causes urbanization in granger sense

renewable energy consumption co2 emissions and oil prices in the g7 countries abstract economic and societal issues related to energy security and global warming is placing greater emphasis on the consumption of renewable energy this paper presents and estimates an empirical model of renewable energy consumption for the g7 countries panel cointegration estimates show that in the long term increases in real gdp per capita and co2 per capita are found to be major drivers behind per capita renewable energy consumption these results are robust across two different panel cointegration estimators oil price increases have a smaller although negative impact on renewable energy consumption deviations from equilibrium are driven mostly by the error correction term as opposed to short term shocks short term deviations from the long term equilibrium take anywhere from between 1 3 years france and 7 3 years japan to correct

changing crude oil price effects on us agricultural employment the effect of changes in the price of crude oil on agricultural employment in the usa between 1947 and 1995 is investigated after reviewing previous assessments of the issue the existence of an empirical relationship between agricultural employment and crude oil price changes is established using granger causality subsequently the nature of the relationship is estimated with the results suggesting that at least three full years are required before the measurable effects of a percentage change in the real price of crude oil on the change in agricultural employment are exhausted finally the structural stability of the functional relationship between the change in agricultural employment and changes in the price of crude oil the percentage changes in expected net farm income realized technological innovation and the wage rate is studied

oil and the macroeconomy when prices go up and down an extension of hamilton s results in an important paper hamilton 1983 demonstrated a strong correlation between oil price changes and gross national product growth in u s data however his study pertained to a period in which all the large oil price movements were upward and thus it left unanswered the question whether the correlation persists in periods of price decline moreover the price variable he used was somewhat distorted by price controls in the 1970s this note investigates whether hamilton s results continue to hold when the sample is extended to include the recent oil market collapse and the oil price variable is corrected for the effects of price controls particular attention is given to the possibility of asymmetric responses to oil price increases and decreases as suggested in the structural employment literature loungani 1986 davis 1987 hamilton 1988 like hamilton i based my investigation on the gnp equation in sims s 1 980b six variable quarterly vector autoregressive model

why do some emerging economies proactively accelerate the adoption of renewable energy abstract this article analyses the determinants of renewable energy consumption in a panel of six major emerging economies namely brazil china india indonesia philippines and turkey that are proactively accelerating the adoption of renewable energy using fully modified ordinary least square fmols dynamic ordinary least square dols and granger causality methods this paper finds that in the long run renewable energy consumption is significantly determined by income and pollutant emission in brazil china india and indonesia while mainly by income in philippines and turkey causal link between renewable energy and income and between renewable energy and pollutant emission are found to be bidirectional in the short run these results suggest that the appropriateness of the efforts undertaken by emerging countries to reduce the carbon intensity by increasing the energy efficiency and substantially increasing the share of renewable in the overall energy mix

implications of oil prices shocks for the major emerging economies a comparative analysis of brics abstract this study analyses the implications of oil prices shocks for the brics economies we employed a time varying structural vector autoregressive tv sva framework in which the sources of time variation are the coefficients and variance covariance matrix of the innovations the quarter frequency data for the period of 1987qii 2017qii is used for the empirical analysis the key findings suggest that there are substantial differences and asymmetries in the response of these economies to oil shocks these differences were profound between and even within oil exporters and importers it shows that between major oil exporters i e russia and brazil the former s economy is rather more intensively influenced by oil prices shocks between the two largest net oil importers i e india and china comparatively the indian economy seems to be rather more vulnerable to oil prices shocks in terms of their adverse effects on gdp inflation and balance of trade the dependence of economies on oil and an increasing level of consumption continue to pose policy challenges for prices and economic stability the analysis on south africa also shows negative impacts of oil prices shocks however the effects are comparatively more time variant than other brics members while these asymmetries indicate significant differences in the structure of these economies they also indicate venues of cooperation and stronger trading relationships to overcome the adverse shocks and mutual development

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

empirical analysis of macroeconomic time series var and structural models abstract var and structural econometric models have complementary roles in the modelling of macroeconomic time series a constant parameter var provided it is statistically well specified constitutes a valid basis for testing hypotheses of dynamic specification exogeneity and a priori structure thus facilitating model evaluation as well as suggesting a potentially efficient model development strategy deterministic e g trends and regime shifts and stochastic e g integrated variables non stationarities are analysable within this framework and the johansen maximum likelihood procedure for cointegrated systems is used in an analysis of the determination of earnings prices productivity and unemployment in the u k

unemployment in britain male unemployment in britain has risen from around 2 per cent in the 1950s to around 17 per cent in 1985 see figure 1 the figures are for male unemployment because there is no consistent series for women 1 even more remarkably unemployment has fallen in only three years out of the last twenty 1973 1978 and 1979 to account for this we need a model that explains both changes in the natural or non accelerating inflation rate of unemployment nairu and deviations from it we use a three equation supply side model centred on the labour market this has two main features the first concerns the determination of employment in the short run the labour demand function that we use cuts through the fruitless debate now raging especially in europe as to whether current unemployment is classical or keynesian according to the classical view employment is too high because real wages are too high according to the keynesian view real wages are not binding and unemployment is high because the product market does not clear with prices too high relative to nominal demand the whole debate is set in the framework of perfect competition yet in perfect competition prices are set by impersonal forces and it is not clear what could possibly stop prices clearing the market it is much more reasonable to think of prices as being set by imperfectly competitive firms existing prices being the best they can think of given the demand they face in this context firms demand for labour will depend on both the real product wage and the level of real aggregate demand this is the demand function we estimate and it conforms both to common sense and to the data however this does not imply that employment can be made to grow without limit by pumping up real demand for in the medium term when price surprises are eliminated our model determines three variables employment real wages and real demand on the basis of three equations an employment equation a price equation and a wage equation thus in the medium term there is a natural level of employment and corresponding to this a natural level of real aggregate demand the second key feature of our model concerns the medium term determination of unemployment in the medium term the planned mark up of wages over prices in wage settlements must be consistent with the mark up of prices over wage costs in employers pricing behaviour for if wage setters try to set real product wages higher than is consistent with employers pricing behaviour this generates ever increasing inflation thus the key to understanding unemployment in the medium term is the behaviour of wage setters if events occur that push them towards too high real wages then unemployment has to rise to offset these influences we shall call these influences wage pressure variables or push factors and they are clearly crucial in understanding unemployment the variables here include the social security system employment protection

industrial conflicts and economic conditions a comparative empirical investigation abstract the empirical work analyses eleven macro series from 1948 to 1975 for seventeen oecd countries including three series for conflicts strikes and lock outs it is demonstrated that the series for the plain number of conflicts are always the best in macro modelling hence conflicts matter less as such than as an indicator of the labour market climate three links between conflicts and the economy are examined i wage inflation is found the main factor generating conflicts ii no production loss due to conflicts appears in our annual macro series iii the main thrust is the examination of the fairly successful role conflicts can play as a push proxy in cost push models finally the strong international elements in both wage inflation and conflicts are discussed

hourly wages and working time in the dutch market sector 1962 1995 this article analyses the joint behaviour of hourly wages and standard hours in the netherlands with respect to the development of full time hours to different hypotheses are suggested work sharing or productivity sharing under the work sharing hypothesis high unemployment would lead to reduced hours whereas under productivity sharing increased productivity leads to higher wages or reduced hours the evidence is in favour of the productivity hypothesis there is no direct impact of unemployment on the evolution of hours moreover although reduced hours tend to increase hourly wages in the short run this is not the case in the long run

topics in the oecd phillips curve how strongly have wages and unemployment been related in oecd countries during the postwar period a simple answer is that on average a one percentage point higher rate of unemployment has been associated with a fall of about one percentage point in the rate of nominal wage increase in the current year compared with the rate of increase a year earlier but such a figure needs interpretation and the aim here is to describe wage behaviour in more detail

the asymmetry of the impact of oil price shocks on economic activities an application of the multivariate threshold model this paper applies the multivariate threshold model to investigate the impacts of an oil price change and its volatility on economic activities changes in industrial production and real stock returns the statistical test on the existence of a threshold effect indicates that a threshold value does exist using monthly data of the us canada and japan during the period from 1970 to 2002 we conclude i the optimal threshold level seems to vary according to how an economy depends on imported oil and the attitude towards adopting energy saving technology ii an oil price change or its volatility has a limited impact on the economies if the change is below the threshold levels iii if the change is above threshold levels it appears that the change in oil price better explains macroeconomic variables than the volatility of the oil price and iv if the change is above threshold levels a change in oil price or its volatility explains the model better than the real interest rate

oil and the macroeconomy since the 1970s economists have long been intrigued by empirical evidence that suggests that oil price shocks may be closely related to macroeconomic performance this interest dates back to the 1970s the 1970s were a period of growing dependence on imported oil unprecedented disruptions in the global oil market and poor macroeconomic performance in the united states thus it was natural to suspect a causal relationship from oil prices to u s macroeconomic aggregates since then a large body of work has accumulated that purports to establish this link on theoretical grounds and to provide empirical evidence in its support we do not attempt a comprehensive survey of this literature but rather provide an idiosyncratic synthesis of what we view as the key issues in this debate and the insights gained over the last 30 years the timing seems right for such an account although the experience of the 1970s continues to play an important role in discussions of the link between oil and the macroeconomy there have been a number of new oil price shocks since the 1970s notably the 1986 collapse of oil prices and the 2000 boom in oil prices as well as the oil price increases associated with the 1990 1991 gulf war and the 2003 iraq war given this richer case history we are arguably in a better position than two decades ago to distinguish the idiosyncratic features of each oil crisis from the systematic effects increases in oil prices have been held responsible for recessions periods of excessive inflation reduced productivity and lower economic growth in this paper we review the arguments supporting such views first we highlight some of the conceptual difficulties in assigning a central role to oil price shocks in explaining

structural adjustment to a terms of trade disturbance the role of relative prices abstract this paper investigates the impact of a terms of trade disturbance on a small economy which responds gradually to changes in relative prices the key intertemporal link is as in dornbusch 1983 between the price of nontraded goods the real interest rate savings and the current account if the traded and nontraded goods are bad substitutes in consumption then an improvement in the terms of trade leads to a transitory current account surplus and conversely international capital mobility reduces the impact of a terms of trade disturbance on relative prices and also reduces the speed with which the economy adjusts to the disturbance

trivariate causality between economic growth urbanisation and electricity consumption in angola cointegration and causality analysis abstract this paper investigates the causal relationship between economic growth urbanisation and electricity consumption in the case of angola while utilizing the data over the period of 1971 2009 we have applied lee and strazicich 2003 the review of economics and statistics 63 1082 1089 2004 working paper department of economics appalachian state university unit root tests to examine the stationarity properties of the series using the gregory hansen structural break cointegration procedure as a complement we employ the ardl bounds test to investigate long run relationships the vecm granger causality test is subsequently used to examine the direction of causality between economic growth urbanisation and electricity consumption our results indicate the existence of long run relationships we further observe evidence in favour of bidirectional causality between electricity consumption and economic growth the feedback hypothesis is also found between urbanisation and economic growth urbanisation and electricity consumption granger cause each other we conclude that angola is energy dependent country consequently the relevant authorities should boost electricity production as one of the means of achieving sustainable economic development in the long run

educating labour force for a green economy and renewable energy jobs in turkey a quantitave approach abstract today the struggle of man against nature has reached the point where nature has been objectified and dominated by resource exploitation as we are faced with huge problems like decreasing natural resources destruction of climate ozone layer glaciers altering the rhythm of seasons global warming decreasing agricultural areas and more negative conditions brought on by the burgeoning human population these problems threaten the life of all living creatures in the natural world itself one critical factor is that humanity must harness the ability to create truly renewable energy sources instead of depleting the natural resources directly in order to generate the energy to sustain the lifestyles of today one aspect of this struggle is to educate the leadership and labour force to actively realize green economies and jobs in the renewable energy sector in the turkish educational system there is a true disconnect between the educational system and the labour markets that is causing a rise in unemployment rates among graduates educating green collar workers is an important opportunity for turkey to develop consistency within the labour markets that have rapidly weakened since 2000 this paper presents an overview of educational policies regarding the development of a green collar industry by facilitating renewable energy jobs through vocational technical high schools and graduate and post graduate university programmes it also analyses state policies on popularising business and industry to actually create green collar jobs for the development of a new social paradigm of sustainable development

the influence of the international oil prices on the real effective exchange rate in romania in a wavelet transform framework article i nfo the purpose of this paper is to assess the empirical influence of oil prices on the real effective exchange rate in romania in a wavelet transform framework more precisely we investigate to what extent oil prices impact the real effective exchange rate in an eastern european transition country characterised by a low level of retail fuel prices and by an important growth rate of these prices as compared to the other eu countries for this purpose we use a discrete wavelet transform approach and scale by scale granger causality tests we find that oil prices have a strong influence on the real effective exchange rate in the short run but also for large time horizons these results are important considering the fact that in a classical granger causality linear framework for the entire sample we find that oil prices have no influence on the real effective exchange rate the findings remainrobust whenresampling the initial 1986 2009period orwhen weuse analternative continuous wavelet transform in addition we discover that mainly the positive shocks associated with an increase in oil prices have an impact upon the real effective exchange rate movements in the short and long runs

the effects of oil price shocks on asian exchange rates evidence from quantile regression analysis abstract this paper investigates the effects of oil price shocks on asian exchange rates we employ quantile regression analysis and allow for structural breaks and asymmetry our results indicate that positive and negative oil price shocks have asymmetrical effects on exchange rate returns that vary in significance size and sign throughout the distribution of exchange rate returns the impact of oil price shocks is also affected by market conditions bearish and bullish currency markets during bullish markets in domestic currencies at lower quantiles of currency movements in terms of u s dollar exchange rates rising oil prices cause further appreciation for indonesia korea the philippines and thailand currencies during bearish markets in the domestic currencies at higher quantiles of exchange rate movements in terms of u s dollar exchange rates rising falling oil price causes further currency depreciation for indonesia malaysia thus currencies respond differently to oil price shocks under extreme bullish or bearish currency market conditions and the impact of rising or falling oil prices on foreign exchange markets can vary by country and market conditions
