oil price shocks and gdp growth do energy shares amplify causal effects abstract the paper estimates the effect of oil price fluctuations on gdp growth using linear and nonlinear var models with data from 12 countries by using an ivar approach it reports strong significance for the existence of non linear moderator effects caused by a decline in the oil to energy share which weakens the causal effect of oil prices on economic growth a consideration of the relationship of oil prices and gdp over 44 years confirms the exclusion of symmetry of previous studies moreover the paper indicates that the effect of negative oil price movements is causal for more countries than has been suggested so far

oil and the macroeconomy a markov state switching approach this paper analyzes the relationship between oil price shocks and postwar u s business cycle fluctuations the authors develop a generalized markov switching model of output that includes a measure of net real oil price increases and examine the capabilities of this variable to generate shifts in the mean of gdp growth and to predict transitions between dichotomous growth phases the results indicate that while the behavior of oil prices has been a contributing factor to the mean of low growth phases of output movements in oil prices generally have not been a principal determinant in the historical evidence of these phases copyright 1997 by ohio state university press

a dynamic service quality cost model with word of mouth advertising abstract a dynamic cost model is developed which describes the evolution of demand for a service from its beginning transient phase to its long term equilibrium the model includes parameters which relate to word of mouth advertising this advertising causes transitions between unaware positively aware and negatively aware states of consumers and thus affects service demand model simulations reveal some generally useful guidelines for service providers 1 it is unwise to expand service operations excessively during the early phases of the service offering in order to handle strong demand the model shows that the demand typically peaks at this early stage before settling down to an equilibrium rate 2 because of customer sensitivity to service quality cost reductions that deteriorate service quality are likely to be a poor policy and 3 it is a good strategy to adopt a high service quality from the beginning rather than to improve it later this is because the impact of good service on the customer base is more rapid in the startup phase than in the long term equilibrium phase

energy consumption at business cycle horizons the case of the united states in this paper we propose a simple extension to a keynesian type macro model by augmenting it with energy consumption we show the relationship between energy consumption and output in a macroeconomic setting and ask the question do permanent shocks dominate changes in energy consumption and output at business cycle horizons for the united states to achieve the goal of this paper we undertake a variance decomposition analysis of shocks based on a common trend and common cycle framework within a vector error correction model our main finding is that permanent shocks explain the bulk of the variations in energy consumption and output at business cycle horizons for the united states

oil price shocks and their short and long term effects on the chinese economy a considerable body of economic literature shows the adverse economic impacts of oil price shocks for the developed economies however there has been a lack of empirical study of this kind on china and other developing countries this paper attempts to fill this gap by answering how and to what extent oil price shocks impact china s economy emphasizing on the price transmission mechanisms to that end we develop a structural vector auto regressive model our results show that an oil price increase negatively affects output and investment but positively affects inflation rate and interest rate however with the differentiated price control policies for materials and intermediates on the one hand and final products on the other hand in china the impact on real economy represented by real output and real investment lasts much longer than that to price monetary variables our decomposition results also show that the short term impact namely output decrease induced by the cut of capacity utilization rate is greater in the first one to two years but the portion of the long term impact defined as the impact realized through an investment change increases steadily and exceeds that of short term impact at the end of the second year afterwards the long term impact dominates and maintains for quite some time

macro economy stock market and oil prices do meaningful relationships exist among their cyclical fluctuations this paper examines the relationship among consumer price index industrial production stock market and oil prices in greece initially we use a unified statistical framework cointegration and vecm to study the data in levels we then employ a multivariate var model to examine the relationship among the cyclical components of our series the period of the study is from 1996 1 to 2008 6 findings suggest that oil prices and the stock market exercise a positive effect on the greek cpi in the long run cyclical components analysis suggests that oil prices exercise significant negative influence to the stock market in addition oil prices are negatively influencing cpi at a significant level however we find no effect of oil prices on industrial production and cpi finally no relationship can be documented between the industrial production and stock market for the greek market the findings of this study are of particular interest and importance to policy makers financial managers financial analysts and investors dealing with the greek economy and the greek stock market

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

the asymmetric impact of oil prices interest rates and oil price uncertainty on unemployment in the us abstract in this study we investigate the presence of asymmetric interactions between oil prices oil price uncertainty interest rates and unemployment in a cointegration framework utilizing the nonlinear auto regressive distributed lag nardl approach we show the asymmetric responses of unemployment to changes in oil prices oil price uncertainty and interest rates in the long run more specifically the results of our analyses suggest that an increase in oil price results in increased unemployment while there is no significant impact of reduced oil prices on the one hand reduced oil price uncertainty leads to a decrease in unemployment whereas an increase in oil price uncertainty does not have an impact we also observe increased unemployment in response to a decrease in interest rates as the impact of increased interest rates is not significant last but not least we find that option implied oil price volatility as a measure of oil price uncertainty outperforms the conditional volatility of crude oil prices in predicting unemployment this study provides valuable implications for policymakers to design sound economic policies

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

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 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

futures hedging effectiveness under the segmentation of bear bull energy markets abstract this article undertakes eight hedging models regression md garch bekk garch ccc garch ecm md ecm bekk ecm ccc and state space models to investigate hedging effectiveness of different price scenarios in energy futures markets different models have systematically evidenced that hedging effectiveness is higher in an increasing pattern termed bull markets than in a decreasing pattern termed bear markets for crude oil and gasoline futures that is findings show asymmetric hedging performance between upward and downward price trends consistently from the most popular hedging models in literature out of sample examination also suggests that the ranking of hedging effectiveness of different hedging models is not parallel in different price patterns across futures contracts implying that investors should adjust their hedging strategies accordingly

understanding the large negative impact of oil shocks this paper oers a plausible explanation for the close link between oil prices and aggregate macroeconomic performance in the 1970s although this link has been well documented in the empirical literature standard economic models are not able to replicate this link when actual oil prices are used to simulate the models in particular standard models cannot explain the depth of the recession in 1974 75 and the strong revival in 1976 78 based on the oil price movements in that period this paper argues that a missing multiplier accelerator mechanism from standard models may hold the key

the effects of oil price shocks on the iranian economy abstract the iranian economy is highly vulnerable to oil price fluctuations this paper analyzes the dynamic relationship between oil price shocks and major macroeconomic variables in iran by applying a var approach the study points out the asymmetric effects of oil price shocks for instance positive as well as negative oil price shocks significantly increase inflation we find a strong positive relationship between positive oil price changes and industrial output growth unexpectedly we can only identify a marginal impact of oil price fluctuations on real government expenditures furthermore we observe the dutch disease syndrome through significant real effective exchange rate appreciation

regulation the opec oil supply shock and wealth effects for electric utilities a popular view among specialists in electric utility economics is that the regulatory process exacerbated the negative effects of the opec s oil price increases during the 1970s in contrast peltzman s theory of regulation suggests that regulators should buffer a firm from cost increases this paper examines these contending propositions by examining the stock returns for a sample of electric utilities during the opec oil shock of october 1973 the data are more consistent with a buffering effect than a regulatory lag

renewable energy oil prices and economic activity a granger causality in quantiles analysis this paper analyzes the causal relationship between renewable energy consumption oil prices and economic activity in the united states from july 1989 to july 2016 considering all quantiles of the distribution although the concept of granger causality is defined for the conditional distribution the majority of papers have tested granger causality using conditional mean regression models in which the causal relations are linear we apply a granger causality in quantiles analysis that evaluates causal relations in each quantile of the distribution under this approach we can discriminate between causality affecting the median and the tails of the conditional distribution we find evidence of bi directional causality between changes in renewable energy consumption and economic growth at the lowest tail of the distribution besides changes in renewable energy consumption lead economic growth at the highest tail of the distribution our results also support the unidirectional causality from fluctuations in oil prices to economic growth at the extreme quantiles of the distribution finally we find evidence of lower tail dependence from changes in oil prices to changes in renewable energy consumption our findings call for government policies aimed at developing renewable energy markets to increase energy efficiency in the u s

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

oil and stock market volatility a multivariate stochastic volatility perspective abstract this paper models the volatility of stock and oil futures markets using the multivariate stochastic volatility structure in an attempt to extract information intertwined in both markets for risk prediction it offers four major findings first the stock and oil futures prices are inter related their correlation follows a time varying dynamic process and tends to increase when the markets are more volatile second conditioned on the past information the volatility in each market is very persistent i e it varies in a predictable manner third there is inter market dependence in volatility innovations that hit either market can affect the volatility in the other market in other words conditioned on the persistence and the past volatility in their respective markets the past volatility of the stock oil futures market also has predictive power over the future volatility of the oil futures stock market finally the model produces more accurate value at risk estimates than other benchmarks commonly used in the financial industry

opec s oil exporting strategy and macroeconomic in stability aguiar conraria and wen 2008 argued that dependence on foreign oil raises the like lihood of equilibrium indeterminacy economic instability for oil importing countries we argue that this relation is more subtle the endogenous choices of prices and quantities by a cartel of oil exporters such as the opec can aect the directions of the changes in the likelihood of equilibrium indeterminacy we show that uctuations driven by self ful lling expectations under oil shocks are easier to occur if the cartel sets the price of oil but the re sult is reversed if the cartel sets the quantity of production these results oer a potentially interesting explanation for the decline in economic volatility i e the great moderation in oil importing countries since the mid 1980s when the opec cartel changed its market strategies from setting prices to setting quantities despite the fact that oil prices are far more volatile today than they were 30 years ago

dynamics of electricity consumption oil price and economic growth global perspective this study uses the data from 157 countries from 1960 to 2014 to analyze the relationship between economic growth electricity consumption oil prices capital and labor the economic growth of developing countries with industrial infrastructure has a more significant association with electricity consumption than oil prices we use oil prices and electricity consumption jointly to study highly predictive observations for economic growth the data are categorized by income oecd and regional levels the panel cointegration long run parameter estimation and pool mean group tests are used to analyze the cointegration and short run and long run relationships between the variables the empirical results indicate the presence of cointegration between the variables the presence of feedback effects between electricity consumption and economic growth oil prices and economic growth is valid these findings confirm that in spite of the oil prices developing countries rely heavily on electricity consumption for economic growth in the short run growth and feedback effects suggest that more vigorous electricity policies should be implemented to attain sustainable economic growth for the long term

oil shock and economic growth in japan a nonlinear approach abstract this paper investigates the relationship between oil price shock and economic growth on the basis of the nonlinear approach developed by hamilton hamilton j 2001 a parametric approach to flexible nonlinear inference econometrica 537 573 we use the approach also in hamilton hamilton j 2003 what is an oil shock journal of econometrics 363 398 of capturing this relationship in japan in a nonlinear model the idea is that negative oil price shocks price increase tend to have larger impact on growth than positive shocks do our empirical evidence confirmed the existence of nonlinearity between these two variables and a flexible nonlinear model is estimated additionally several other form of nonlinearity are estimated and tested

relationships between oil price shocks and stock market an empirical analysis from china this paper investigates the interactive relationships between oil price shocks and chinese stock market using multivariate vector auto regression oil price shocks do not show statistically significant impact on the real stock returns of most chinese stock market indices except for manufacturing index and some oil companies some important oil price shocks depress oil company stock prices increase in oil volatility may increase the speculations in mining index and petrochemicals index which raise their stock returns both the world oil price shocks and china oil price shocks can explain much more than interest rates for manufacturing index

oil price fluctuations and u s dollar exchange rates adding oil prices to the monetary model of exchange rates we find that oil prices significantly explain movements in the value of the u s dollar usd against major currencies from the 1970s to 2008 our long run and forecasting results are remarkably consistent with an oil exchange rate relationship increases in real oil prices lead to a significant depreciation of the usd against net oil exporter currencies such as canada mexico and russia on the other hand the currencies of oil importers such as japan depreciate relative to the usd when the real oil price goes up

scarcity resource price uncertainty and economic growth over the course of the past decade significant steps have been taken to empirically link indicators of resource scarcity to changes in economic growth this paper extends this previous literature in two ways first rather than concentrating exclusively on energy we focus on the technological change embodied in the prices of an array of complementary natural resource inputs second we investigate using g arch methods the importance of resource price uncertainty as well as resource price levels on aggregate economic growth we find that output growth is significantly influenced by both resource price levels and resource price uncertainty

oil shocks and aggregate macroeconomic behavior the role of monetary policy a recent paper by bernanke gertler and watson 1997 suggests that monetary policy could be used to eliminate any recessionary consequences of an oil price shock this paper challenges this conclusion on two grounds first we question whether the federal reserve actually has the power to implement such a policy for example we consider it unlikely that additional money creation would have succeeded in reducing the fed funds rate by 900 basis points relative to the values seen in 1974 second we point out that the size of the effect that bernanke gertler and watson attribute to oil shocks is substantially smaller than that reported by other researchers primarily due to their choice of a shorter lag length than that used by other researchers we offer evidence in favor of the longer lag length employed by previous research and show that under this specification even the aggressive federal reserve policies proposed would not have succeeded in averting a downturn

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

electricity consumption oil price and economic growth global perspective abstract the study uses the panel data of 210 countries over the period 1960 2014 to analyze the empirical relationship between economic growth electricity consumption oil price gross fixed capital formation and population while the current literature on the topic focus largely on relationship between oil consumption and economic growth while only a few presented the research studying relationship between electricity and economic growth we used oil price and electricity consumption jointly to study the highly predictive observer for economic growth furthermore the data is categorized into income oecd regional level renewable energy consumption level and oil export import countries pedroni panel cointegration fully modified ols and panel vector error correction test apply to analyze the cointegration short run and the long run relationship between the variables the results of full panel confirm a bidirectional relationship between electricity consumption and gdp oil price and gdp fixed capital formation population and gdp moreover the results confirm that countries using non renewable sources for electricity generating such as through coal and oil the electricity consumption of these countries exhibit a negative relationship with the economic growth furthermore the finding varies across income oecd and regional renewable energy consumption level

historical energy price shocks and their changing effects on the economy abstract the purpose of this paper is to identify the changes in the impact of energy shocks on economic activity with an interest in assessing if an economy s vulnerability and resilience to shocks improved with economic development using data on the united kingdom over the last three hundred years the paper identifies supply aggregate demand and residual shocks to energy prices and estimates their changing influence on energy prices and gdp the results suggest that the impacts of supply shocks rose with its increasing dependence on coal and declined with its partial transition to oil however the transition from exporting coal to importing oil increased the negative impacts of demand shocks more generally the results indicate that improvements in vulnerability and resilience to shocks did not progress systematically as the economy developed instead the changes in impacts depended greatly on the circumstances related to the demand for and supply of energy sources if these experiences are transferable to future markets a transition to a diversified mix of renewable energy is likely to reduce vulnerability and increase resilience to energy price shocks

realized volatility transmission between crude oil and equity futures markets a multivariate har approach this paper differs from extant literature because it studies volatility co movements with a multivariate orthogonalized har model a flexible specification for the time series of realized volatility which is able to identify short mid and long term spillover effects we examine volatility transmission mechanisms using high frequency data of the stock index futures on s p 500 nikkei 225 ftse 100 and the futures on the west texas intermediate crude oil during the period from september 2002 to september 2012 considering the full sample the short term volatility of the equity futures contains information about future oil volatility incremental to the information inherent in the time series of oil volatility on the other hand weekly and monthly volatilities do not exhibit a significant spillover effect breaking the whole sample into three subsamples no significant granger causalities are observed in the pre crisis period while in the crisis time and its aftermath we document that the us and uk equity market volatilities to granger cause the oil futures volatility which itself leads the japanese market in terms of magnitude we observe an increase in the short term volatility spillover over time studying the residuals of the har transmission models within a ccc dcc garch framework reveals increasing instantaneous correlation between the energy and equity volatilities in the course of time

a wavelet analysis of mean and volatility spillovers between oil and brics stock markets this paper investigates the spillover effects of volatility and shocks between oil prices and the brics stock markets using multivariate approach and wavelet analysis at different time horizons hence we combine a multivariate arma garch model and wavelet multiresolution analysis to study this phenomenon a bivariate arma 1 1 garch 1 1 cdcc student t model was joined with modwt filter to capture a broad range of possible spillover effects in mean and variances of level prices at various time horizons generally empirical results provide strong evidence of time varying volatility in all markets under study however our proposed approach shows that oil price and stock market prices are directly affected by their own news and volatilities and indirectly affected by the volatilities of other prices and wavelet scale the results show also that mean and volatility spillover effects was decomposed into many sub spillovers on different time scales according to heterogeneous investors and market participants the practical implications of this study are critical innovative and useful for the local and international investors and also for the portfolio managers they can utilize this study to formulate the optimal oil bricks stock portfolios as well as lead to more accurate predictions of volatility spillovers patterns also in developing their hedging strategies

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

an empirical analysis of the relationship between oil prices and the chinese macro economy using the quarterly data from the first quarter of 1996 to the fourth quarter of 2014 this paper studies the relationship between oil prices and the chinese macro economy we find output and interest rate respond significantly to oil price shocks further analysis reveals that the positive response of output to oil price shocks is attributed to the influences of oil price shocks on exports the oil price shocks have both longer and deeper effects on the exports of state owned enterprises than on those of foreign investment enterprises moreover the response of exports to oil price shocks is symmetric finally oil prices are found to be useful for forecasting the china s exports in the periods shorter than about two years

what happened to the oil price macroeconomy relationship abstract strong evidence is found that oil prices no longer granger cause many u s macroeconomic indicator variables in data after 1973 a number of potential explanations are explored that sample stability issues are responsible that oil prices are now endogenous and that linear and symmetric specifications misrepresent the form of the oil price interaction none of these hypotheses are supported by the data the opec price increases do appear to have had significant impacts while the effects of the price declines of the 1980s are smaller and harder to characterize these results have potentially important implications for the large body of research which utilizes oil prices as an instrumental or explanatory variable

declining effects of oil price shocks in recent years output responses to oil price shocks have not only been weaker but have also reached their trough earlier this paper builds a model that incorporates a realistic structure of u s petroleum consumption and explores three possible explanations for the changes the possible factors considered are i deregulation in the transportation industry ii improved energy efficiency and iii a lower degree of persistence of oil price shocks under realistic parameter values the three factors play an important role quantitatively accounting for half of the reduction in the largest impact on output of an oil price shock over time

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

the impact of oil price shocks evidence from the industries of six oecd countries most of the studies about the macroeconomic consequences of oil price shocks have been focused on us aggregate data in contrast to these studies this paper empirically assesses the dynamic effect of oil price shocks on the output of the main manufacturing industries in six oecd countries the pattern of responses to an oil price shock by industrial output is diverse across the four european monetary union emu countries under consideration france germany italy and spain but broadly similar in the uk and the us moreover evidence on cross industry heterogeneity of oil shock effects within the emu countries is also reported

exploiting the oil gdp effect to support renewables deployment the empirical evidence from a growing body of academic literature clearly suggests that oil price increases and volatility dampen macroeconomic growth by raising inflation and unemployment and by depressing the value of financial and other assets surprisingly this issue seems to have received little attention from energy policy makers in percentage terms the oil gdp effect is relatively small producing losses in the order of 0 5 of gdp for a 10 oil price increase in absolute terms however even a 10 oil price rise oil has risen at least 50 in the last year alone produces gdp losses that could they have been averted would significantly offset the cost of increased re deployment this paper draws on the empirical oil gdp literature which we summarize to show that i by displacing gas and oil renewable energy investments can help nations avoid costly macroeconomic losses produced by the oil gdp effect and ii that these avoided losses represent a significant external macroeconomic benefit of such investments we show that a 10 increase in re share avoids gdp losses in the range of 29 53 billion in the us and the eu 49 90 billion for oecd these avoided losses offset one fifth of the re investment needs projected by the erec and half the oecd investment projected by a g 8 task force for the us the figures further suggest that each additional kw of renewables on average avoids 250 450 in gdp losses a figure that varies across technologies as a function of annual capacity factors we approximate that the offset is worth 200 kw for wind and solar and 800 kw for geothermal and biomass while we focus only on renewables the gdp offset will apply in some measure to other non fossil technologies including energy efficiency dsm and nuclear the societal valuation of non fossil alternatives must reflect these avoided gdp losses whose benefit is not fully captured by private investors this said we fully recognize that wealth created in this manner does not directly form a pool of public funds that is easily earmarked for renewables support finally the oil gdp relationship has important implications for correctly estimating direct electricity generating cost for conventional and renewable alternatives and for developing more useful energy security and diversity concepts we also address these issues

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 revenue shocks and government spending behavior in iran abstract oil revenues play an important role in the political economy of iran on average 60 of the iranian government revenues and 90 of export revenues originate from oil and gas resources current international sanctions on iran have mainly targeted the oil production capacity of iran and its exports to the global markets in this study we analyze the dynamic effects of oil shocks on different categories of the iranian government expenditures from 1959 to 2007 using impulse response functions irf and variance decomposition analysis vdc techniques the main results show that iran s military and security expenditures significantly respond to a shock in oil revenues or oil prices while social spending components do not show significant reactions to such shocks

oil price uncertainty and unemployment abstract in this study we empirically search the effects of oil price uncertainty and oil price shocks on u s unemployment rate using a garch in mean var model for the period 1974 q2 2017 q4 based on our findings we show that oil price uncertainty significantly increases unemployment rate in the u s economy likewise our impulse response analysis affirms that a positive oil price shock increases unemployment while the response of unemployment to a negative oil price shock is negative moreover we reveal that unemployment rate reacts to positive and negative shocks asymmetrically more specifically the response of unemployment to negative oil price shocks is negative and slighter in size besides oil price uncertainty is found to magnify the rise in the u s unemployment rate these findings are in keeping with the real options theory which reveals that the uncertainty about goods prices leads firms to postpone or abandon their production and investment and they seem to be robust to the use of different real oil price measures

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

intracountry evidence on the lucas variance hypothesis intracountry evidence on the lucas variance hypothesis i introduction seventeen years ago lucas 1973 developed an aggregate supply model that challenged the efficacy of neo keynesian macroeconomic stabilization policy and significantly altered the development of macroeconomic models employing a multimarket stochastic equilibrium model lucas assumed that individual suppliers decide how much to produce based on perceived relative prices their expectations of future prices and demand are formed rationally using all available information about specific and economy wide prices and quantities changes in market specific prices however reflect both changes in the general price level and changes in relative prices individual suppliers cannot distinguish between the two because they have instantaneous information about their own specific prices but only lagged information about the general price level thus a current unanticipated increase in the general price level and nominal aggregate demand will be partly perceived by suppliers as an increase in the relative price and relative demand for their goods and they will temporarily increase output a highly volatile general price level and nominal aggregate demand result in less general relative price confusion and a fading of the short run output inflation tradeoff that is the lucas model suggests an inverse relationship between the output inflation tradeoff and the variability of the rate of inflation and the rate of change of nominal aggregate demand lucas used a sample of eighteen countries to see whether the terms of the output inflation tradeoff vary across countries in the way predicted by the natural rate theory 1973 330 he estimated the following reduced form supply function over the 1952 67 period y sub ct pi delta pi delta chi sub t lambda y sub c t 1 1 where y sub ct is detrended real gnp delta chi sub t is the change of the natural logarithm of nominal gnp delta is the average rate of demand expansion lambda is the speed of adjustment with lambda less than to 1 and pi is the response of real gnp to changes in nominal gnp with 0 is not less than or equal to pi is not less than or equal to 1 since the estimated tradeoff coefficients were found to be greater for a group of sixteen stable countries than for two highly volatile countries lucas argued that the behavior of the estimated pi values across countries is in striking conformity with the natural rate hypothesis 1973 332 empirical studies by albero 1981 attfield and duck 1983 fernadez 1977 hanson 1980 hercowitz 1983 and koskela and viren 1980 have generally provided cross country evidence supporting luca s variance hypothesis froyen and waud 1980 however presented in addition to cross country evidence limited intracountry evidence for 1 the relationship between the output inflation tradeoff and the variances of the rate of change of nominal income and the price level and 2 the relationship between the variance of the inflation rate and the variance of the rate of change of nominal income they examined these relationships on a cross country basis for each of ten industrialized countries for the 1956 76 period the 1957 66 and 1967 76 subperiods were used to make intracountry comparisons in individual countries their cross country and intracountry results support the hypothesis that the output inflation tradeoff and the variance of the inflation rate are inversely related their evidence however does not suggest that the variance of the rate of change of nominal income is negatively correlated with the tradeoff and positively correlated with the variance of the inflation rate 1 it is assumed in luca s paper and all other cross country studies that the slope of the supply curve gamma and the variance of the specific market price from its economy wide average tau

economic impact of oil price shocks on the turkish economy in the coming decades a dynamic cge analysis as a small open economy turkey depends on both imported oil and natural gas importing almost two thirds of its primary energy demand this paper analyzes the economic effects of oil price shocks for turkey as a small open oil and gas importing country to analyze the potential long term effects of oil price shocks on macroeconomic variables of interest including gdp consumer price inflation indirect tax revenues trade balance and carbon emissions we developed turgem d a dynamic multisectoral general equilibrium model for the turkish economy using turgem d we analyzed the impact of oil price shocks under three distinct scenarios reference high and low oil prices the simulation results show that these oil prices have very significant effects on macro indicators and carbon emissions in the turkish economy

relationship between oil prices interest rate and unemployment evidence from an emerging market abstract while the interrelation between oil price changes economic activity and employment is an important issue that has been studied mainly for developed countries little attention has been devoted to inquiries on fluctuations in the price of crude oil and its impact on employment for small open economies adopting an efficiency wage model for equilibrium employment that does not require any assumptions regarding labor supply this paper contributes to the literature by investigating the causality between unemployment and two input prices namely energy crude oil and capital real interest rate in an emerging market turkey for the period 2005 01 2009 08 applying a relatively new technique the toda yamamoto procedure we find that the real price of oil and interest rate improve the forecasts of unemployment in the long run this finding supports the hypothesis that labor is a substitute factor of production for capital and energy

oil price fluctuation volatility spillover and the ghanaian equity market implication for portfolio management and hedging effectiveness abstract this study attempts to contribute to the literature on stock markets and energy prices by examining the dynamic volatility and volatility transmission between oil and ghanaian stock market returns in a multivariate setting using the recently developed var garch var agarch and dcc garch frameworks in turn the models results are used to compute and analyze the optimal weights and hedge ratios for oil stock portfolio holdings for comparison purposes and to put the paper more in the perspective of west africa the nigerian stock market is also included in the analysis our findings point to the existence of significant volatility spillover and interdependence between oil and the two stock market returns while spillover effects are stronger for nigeria the transmission of volatility is much more apparent from oil to stock than from stock to oil in the case of ghana also the study demonstrates evidence of short term predictability in oil and stock price changes through time and reveals that conditional volatility changes more rapidly as result of substantial effects of past volatility rather than past news shocks for all market returns moreover we show that there is a slightly more effective hedge in the two stock markets under the dcc garch framework our preferred model compared to the other two models although hedging effectiveness is much greater for ghana on the whole our findings for optimal hedge ratios are consistent with other studies and particularly the view that oil assets should be an integral part of a diversified portfolio of stocks and suggest that a better understanding of volatility links is crucial for portfolio management in the presence of oil price risk finally the existence of multivariate asymmetric effects and dynamic conditional correlations as revealed by the var agarch and dcc garch models make it clear that the assumptions of symmetric effects and constant conditional correlations are not supported empirically

reconciling the conflict between the pollution haven hypothesis and an emerging trajectory of international technology transfer abstract many developing countries have relied on technology transfer through foreign direct investment fdi from developed countries as a primary means of technology acquisition however recent increased global eco consciousness and linking of trade and investment with environmental issues has the potential of disrupting these investment flows this paper investigates the validity of the pollution haven hypothesis which claims that an open market regime will encourage the flow of generally low technology polluting industries to developing countries from a neo technology trade perspective in the process an emerging trajectory of international technology transfer favoring high technology industries is established this paper concludes that positive measures enhancing fdi is not only crucial for technology upgrading but at the same time brings about enhanced environmental welfare through transfer of eco friendly products and production processes

exploring the oil price and real gdp nexus for a small island economy the fiji islands the goal of this paper is to examine the relationship between real gdp and oil prices using time series data for the period 1970 2005 our main finding is that an increase in oil has a positive albeit inelastic impact on real gdp inconsistent with the bulk of the literature we argue that this is not a surprising result for the fiji islands our central argument focuses on two aspects of the fijian economy 1 the fact that actual output in fiji has been around 50 per cent less than potential output thus fiji s actual output has not reached a threshold level at which oil prices can negatively impact output and 2 a rise in oil prices filters through to value added which in turn is reflected in a larger actual output

oil prices and economic activity an asymmetric cointegration approach the aim of this paper is to study the long term relationship between oil prices and economic activity proxied by gdp to account for asymmetries existing in the links between the two variables we propose an approach based on asymmetric cointegration our empirical analysis concerns the u s economy but also the g7 europe and euro area economies results indicate that while standard cointegration is rejected there is evidence for asymmetric cointegration between oil prices and gdp

the causal nexus between oil prices and equity market in the u s a regime switching model abstract the aim of this paper is to analyse the causal link between monthly oil futures price changes and a sub grouping of s p 500 stock index changes the causal linkage between oil and stock markets is modelled using a vector autoregressive model with time varying parameters so as to reflect changes in granger causality over time a markov switching vector autoregressive ms var model in which causal link between the series is stochastic and governed by an unobservable markov chain is used for inferring time varying causality although we do not find any lead lag type granger causality the results based on the ms var model clearly show that oil futures price has strong regime prediction power for a sub grouping of s p 500 stock index during various sub periods in the sample while there is a weak evidence for the regime prediction power of a sub grouping of s p 500 stock indexes the regime prediction non causality tests on the ms var model show that both variables are useful for making inference about the regime process and that the evidence on regime prediction causality is primarily found in the equation describing a sub grouping of s p 500 stock market returns the evidence from the conditional non causality tests shows that past information on the other series fails to improve the one step ahead prediction for both oil futures and stock returns

interdependence of oil prices and stock market indices a copula approach article i nfo article history in this paper we study the relationship between the oil price and stock market index of various countries between 1982 and 2007 we exclude oil and gas stock companies from the stock indices to remove the obvious direct linkage oil price series are converted into local currency to account for possible exchange rate effects the method of copula is used to model the general dependence between stock returns and oil price returns our findings suggest a weak dependence between oil prices and stock indices for most cases which are consistent with the results from previous studies exceptions are for the stock index returns of large oil consuming and producing countries united states and canada which are shown to have a relatively strong dependence with the oil price series the introduction of euro in 1999 altered considerably dependence between oil prices and stock returns

macroeconomic performance of oil price shocks outlier evidence from nineteen major oil related countries regions abstract as a special energy commodity oil price shocks can affect not only the energy market but also the performance of the macroeconomy this research provides complementary explanations for nineteen major oil related countries regions macroeconomic effects caused by unexpected oil price changes it focuses on the macroeconomic performance of oil price shocks from outlier perspective investigating the inner hidden factors of co movements between oil price shocks and macroeconomy three methods called empirical covariance ec method robust covariance rc method and one class support vector machine svm method are used in the outlier detection empirical results show that a one class svm method has the best environmental adaptability for detecting the outlier performance of the co movements between oil price shocks and macroeconomy followed by ec and rc methods b according to the time axis the outlier performances of gross domestic production consumer price index and unemployment rate are all concentrated in 2005 2014 which is highly consistent with the oil price shock process and c according to the spatial axis countries four categories with similar outlier performances are obtained outlier performance of macroeconomy of oil related country region in lower levels seems to be worse than that of the country region in higher levels which can be attributed to more attentions paid by higher leveled oil related countries on the oil price shock response system to relieve the severe macroeconomic impacts caused by oil price shocks

dynamic co movement between oil and stock markets in oil importing and oil exporting countries two types of wavelet analysis abstract this study explores the dynamic co movement between oil and six stock markets china india japan saudi arabia russia and canada by using two types of wavelet analysis wavelet multi scale decomposition and wavelet coherence the main empirical results are as follows 1 maximal overlap discrete wavelet transform analysis shows that there are feedback relationships between the price movement of oil and stock markets in all six countries in the wavelet based decomposition at the d4 d5 and d6 scales 2 the pairs of oil and stock returns show high overall co movement at the 16 to 128 week scale based on continuous wavelet transform analysis the wavelet coherence and phase plots show that the pairs of oil and oil importing stock market returns have high co movement for the period between 2007 and 2012 especially during the global financial crisis of 2008 in addition the wavelet coherence and phase plots show that the pairs of oil and oil exporting stock market returns have high co movement from 2007 to 2017 3 oil price returns lead the stock returns of saudi arabia russia and canada from 2007 to 2017 at the 16 to 128 week scale the stock prices are more influenced by oil prices in oil exporting countries than in oil importing countries this evidence implies that the economic structure of oil exporting countries depends strongly on crude oil production 4 from the results of the wavelet based granger causality test there is a lead lag causality linkage in which the oil price leads stock market indices from 27 to 30 weeks 189 210 days the implications of these findings are discussed

diversifying away the risk of war and cross border political crisis this paper investigates the behavior of crude oil prices government bonds and stock market indices around outbreaks of severe international crises and wars using a constant mean return event study we show that these events are associated with positive and significant abnormal returns on oil and bonds which means that these two asset classes can potentially shelter shareholders from plummeting equity values during international crises a formal safe haven analysis confirms this insight such price movements may reflect a reallocation of funds across asset classes in response to the events as well as shifts in the demand for oil due to precautionary speculative and military motives we also calculate the weights for optimal portfolios which could provide insurance against conflict risk

efficiency of crude oil markets evidences from informational entropy analysis abstract the role of crude oil as the main energy source for the global economic activity has motivated the discussion about the dynamics and causes of crude oil price changes an accurate understanding of the issue should provide important guidelines for the design of optimal policies and government budget planning using daily data for wti over the period january 1986 march 2011 we analyze the evolution of the informational complexity and efficiency for the crude oil market through multiscale entropy analysis the results indicated that the crude oil market is informationally efficient over the scrutinized period except for two periods that correspond to the early 1990s and late 2000s us recessions overall the results showed that deregulation has improved the operation of the market in the sense of making returns less predictable on the other hand there is some evidence that the probability of having a severe us economic recession increases as the informational efficiency decreases which indicates that returns from crude oil markets are less uncertain during economic downturns
