multinational operation ownership and efficiency differences in the international oil industry abstract although state involvement in market systems often leads to inefficiency this influence in the oil industry is not dwindling due to strong growth of some state oil companies based on this background there are concerns about how state firms can continue to stay relevant in the international oil industry by offsetting inefficiencies due to state control this study assesses the effects of multinational operations on the performance of oil firms this is achieved by comparing productive and scale efficiencies of state and private oil companies as well as state multinationals and private multinationals a dataset of 50 firms each year from 2001 to 2010 reveals that although multinational operation is important in reducing productive inefficiencies of state firms it does not mitigate scale inefficiencies of state owned firms state firms should therefore make multinational operations a key policy direction since this will provide a transformative agenda towards equally competing with their private counterparts however better efforts need to be paid in reducing scale inefficiencies that are pervasive among state owned oil firms providing better controls on firm size will provide better drive towards future efficient production levels

allocative disturbances and specific capital in real business cycle theories chanted albeit in varying degree with business cycle theories that either posit unexplained nominal wage and price rigidities or rely on misperceptions about nominal variables as a key driving force one response to this disenchantment has been a concentration of research effort on real business cycle theories aside from dissatisfaction with competitor theories the very visible oil price shock episodes of the 1970 s lent plausibility to the view that exogenous real disturbances cause large fluctuations in aggregate economic activity this essay on real business cycle theory considers the role of allocative disturbances in aggregate economic fluctuations when human and physical capital are specialized by allocative disturbances i mean events that impinge on the economy by inducing a costly time consuming reallocation of specialized resources at least since the publication of ricardo s principles in 1817 economists have recognized some of the potentially important aggregate consequences of allocative disturbances ricardo writes

relative energy price and investment by european firms abstract a dynamic model of investment is estimated with data on non financial firms in 15 european countries across 25 industries over 1991 2006 a rise in real energy price reduces the degree of persistence in the investment adjustment cost function panel results suggest that in manufacturing a 1 rise in real energy price reduces investment by a country s firms by 1 9 relative to that by firms in other countries with a smaller effect for non manufacturing firms the negative effect of a higher relative price of energy on firm level investment is significantly less marked the larger the firm results imply that stabilizing the relative price of energy would steady firm investment with greater gains in stability at smaller and medium sized firms results are robust to consideration of country business cycle effect and firm leverage estimation of investment is based on the euler equation approach with over 21 000 observations individual country regressions imply that a rise in the relative price of energy price has a statistically significant negative effect on firm level investment in 14 out of 15 countries to avoid dynamic panel bias estimation is by generalized method of moments with instrumental variables

the effect of 107th opec ordinary meeting on oil prices and economic performances in japan abstract the aim of this paper is to show the influence of the 107th opec ordinary meeting meeting and investigates the relationships between oil prices and economic activities using an exponential generalized autoregressive conditional heteroskedasticity egarch and a vector autoregressive var model from 1991 to 2008 in japan we find that levels and volatilities of oil prices increase after the meeting we examine the effects of it on japanese economic activities employing a granger causality test and data before and after it the empirical result reveals that each price of regular gasoline and diesel has information to be useful to predict the economy after the meeting on the other hand volatilities of regular gasoline and diesel price have information to predict the inflation and economic growth before the meeting respectively after the meeting however these volatilities change to be useful to predictive both inflation and economic growth thus we conclude that the decision of meeting is related to not only the domestic oil prices but also the macroeconomy

rockets and feathers the asymmetric speed of adjustment of uk retail gasoline prices to cost changes abstract the paper develops a quadratic quantity adjustment model to test the hypothesis put forward in the recent monopolies and mergers commission report that the speed of adjustment of uk retail gasoline prices to cost changes is more rapid when costs rise than when they fall and that the adjustment path is more concentrated around the mean value on the upswing using data from 1982 to 1989 evidence of faster and more concentrated responses to cost increases were found

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

oil prices and the rise and fall of the us real exchange rate abstract questions of the relative importance of real vs monetary shocks in explaining exchange rate movements still have no widely accepted answer despite their importance both for the research agenda and for policy questions we examine this issue using a variety of empirical techniques for the us effective exchange rate we find that a stable link exists between oil price shocks and the us real effective exchange rate over the post bretton woods period the results suggest that oil prices may have been the dominant source of persistent real exchange rate shocks and that energy prices may have important implications for future work on exchange rate behavior

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

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

unemployment equilibria and input prices theory and evidence from the united states the paper develops an efficiency wage model where input prices affect the equlibrium rate of unemployment we show that a simple framework based on only two prices the real price of oil and the real rate of interest is able to explain the main post war movements in the rate of u s joblessnss the equations do well in forecasting unemployment many out of sample and provide evidence that the oil price spike associated with iraq s invasion of kuweit appears to be a component of the mystery recession which followed

asymmetries in the responses of regional job flows to oil price shocks this paper studies the effect of oil price innovations on manufacturing job flows across u s states first i estimate a nonlinear structural equation model and compute impulse response functions by monte carlo integration i find asymmetries in the responses of job flows to positive and negative oil price innovations yet these asymmetries do not pass a test of symmetry on the impulse responses especially after accounting for data mining third i use a test for the absence of job reallocation to evaluate whether an unexpected increase in the real price of oil price triggers an important change in job reallocation i find that oil price shocks have limited regional allocative effects

time varying effect of oil market shocks on the stock market abstract a mixture innovation time varying parameter var model is used to examine the impact of structural oil price shocks on u s stock market return time variation is evident in both the coefficients and the variance covariance matrix the standard deviations of the demand side structural shocks reached forty year peaks during the global financial crisis and have remained high since in the real stock return equation the coefficient of global real economic activity has declined since the late 1990s and that of oil market specific demand oil shock has been lower since the early 1990s than before the structural oil shocks account for 25 7 of the long run variation in real stock returns overall with substantial change in levels and sources of contribution over time the contribution of shocks to global real economic activity to real stock return variation rose sharply to 22 in 2009 and remains 17 over 2009 2012 the contribution of oil market specific demand price shocks rose unevenly from 5 in the mid 1970s to about 15 in 2007 with a subsequent decline the contribution of oil supply shocks has trended downward from 17 to 5 over 1973 2012

the general equilibrium costs and impacts of oil price shocks in newfoundland and labrador abstract the 2014 2015 dramatic drop in world oil prices had devastating impacts on a global scale we analyse economic costs and impacts of a negative oil price shock following the 2014 2015 decrease in oil prices on the provincial economy of newfoundland and labrador canada we use a dynamic computable general equilibrium model to estimate a drop in oil prices by inputting the estimated effect as a direct impact to royalties which are the land input in the oil and gas sector of the provincial economy we provide sensitivity to account for the duration and magnitude of the shock as well as the timing of recovery our results suggest that a shock in the price of oil will have its most significant impact on gdp in the initial years over the first five years the reduction in gdp due to this shock would be roughly 2 1 of gdp in our most realistic shock scenario but could be much higher in other scenarios considered a sharp drop in gdp over the first five years will be mitigated somewhat in the long run as the growth in oil prices rises however negative long run impacts to gdp persist due to the oil price shock in 2014 2015 and will worsen if there is a prolonged shock

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

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

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

the world is not enough small open economies and regional dependence in this paper we explicitly introduce regional factors into a global dynamic factor model we combine new open economy factor models emphasizing global shocks with the recent findings of regional importance in the business cycle synchronization literature the analysis is applied to a large panel of domestic data for four small open economies we find that global and regional shocks explain roughly 30 and 20 percent respectively of the business cycle variation in all countries while global shocks have most impact on trade variables regional shocks explain a relatively large share of the variation in cost variables

modeling oil price us stock nexus a varma bekk agarch approach abstract this study adds to the existing literature on oil price us stock nexus in three ways first it employs the varma agarch model developed by mcaleer et al 2009 within the context of bekk framework using west texas intermediate wti and brent as proxies for oil market and s p stocks as a proxy for us stock market secondly it modifies the model to include endogenously determined structural break using the general structure for analyzing breaks with unit roots in perron 2006 third it uses the adopted model to compute optimal portfolio weight and hedge ratios between oil price and us stocks using different sample data based on the break date on average our empirical evidence suggests a significant positive return spillover from us stock market to oil market and bi directional shock spillovers between the two markets in addition there is significant own asymmetric shock effect in both markets while volatility spillover from oil market to stock market became pronounced after the break which coincides with the period of global economic slowdown similarly the results of portfolio management differ across the sample data more importantly we find that ignoring structural break when it exists may exaggerate hedging effectiveness

sectoral shifts and cyclical unemployment a substantial fraction of cyclical unemployment is better characterized as fluctuations of the frictional or natural rate than as deviations from some relatively stable natural rate shifts of employment demand between sectors of the economy necessitate continuous labor reallocation since it takes time for workers to find new jobs some unemployment is unavoidable this paper presents evidence that most of the unemployment fluctuations of the seventies unlike those in the sixties were induced by unusual structural shifts within the u s economy simple time series models of layoffs and unemployment are constructed that include a measure of structural shifts within the labor market these models are estimated and a derived natural rate series is constructed

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 shocks and monetary policy rules in emerging economies we examine the effects of shocks in the oil market on key macroeconomic variables in small open economies using a dynamic stochastic general equilibrium model with sticky prices and imperfect competition under different monetary policy rules the numerical solutions show that the types of exchange rate regimes and monetary policies could partly explain the trends in macroeconomic volatilities considering negative shocks to oil supply hamilton 1983 and positive shocks to oil demand kilian 2009 these findings are confirmed in vector autoregressive responses for chile and israel with inflation targeting under flexible exchange regimes and hong kong with fixed regime

the role of energy prices in the great recession a two sector model with unfiltered data we investigate the role of energy shocks during the great recession we study the behaviour of the uk energy and non energy intensive sectors firms in a real business cycle rbc model using unfiltered data the model is econometrically estimated and tested by indirect inference output contraction during the great recession was largely caused by energy price and sector specific productivity shocks all of which are non stationary and hence tend to dominate the sample variance decomposition we also found that the channel by which the energy price shock reduces output in the model is via the terms of trade these fall permanently when world energy prices increase and as substitutes for energy inputs are strictly limited there are few reactions via production channels therefore there is no other way to balance the deteriorating current account than through lower domestic absorption

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

what caused the early millennium slowdown evidence based on vector autoregressions this paper uses a simple var for the usa and euro area to analyse the underlying shocks of the early millennium slowdown i e supply demand monetary policy and oil price shocks the results of two identification strategies are compared one is based on traditional zero restrictions and as an alternative an identification scheme based on more recent sign restrictions is proposed the main conclusion is that the recent slowdown is caused by a combination of several shocks negative aggregate supply and aggregate spending shocks the increase of oil prices in 1999 and restrictive monetary policy in 2000 these shocks are more pronounced in the usa than the euro area the results are somewhat different depending on the identification strategy it is illustrated that traditional zero restrictions can have an influence on the estimated impact of certain shocks copyright 2005 john wiley sons ltd

oil prices and financial stress a volatility spillover analysis this paper examines whether there is a volatility transmission between oil prices and financial stress by means of the volatility spillover test we employ wti crude oil prices and cleveland financial stress index for the period 1991 2014 and divide the sample into pre crisis in crisis and post crisis periods due to the downward trend in oil price in 2008 the volatility model estimations indicate that oil prices and financial stress index are dominated by long run volatility the volatility spillover causality test supports evidence on risk transfer from oil prices to financial stress before the crisis and from financial stress to oil prices after the crisis the impulse response analysis shows that the volatility transmission pattern has similar dynamics before and after the crisis and is characterized by higher and long lived effects during the crisis our results have implications for both policy makers and investors and for future work

dynamic cyclical comovements between oil prices and us gdp a wavelet perspective abstract in this paper we use wavelet analysis to investigate the cyclical comovements between crude oil prices and us gdp taking into account the decline in the volatility of us gdp growth that has occurred since the mid 1980s our main findings suggest that before 1984 q1 the crude oil prices were leading the us gdp cycle by 3 quarters and granger cause us gdp in contrast after 1984 q1 the crude oil prices were lagging the us business cycle and a reverse causality is found to run from us gdp to oil prices the multiscale granger causality tests globally corroborate theses results

cross country differences in the effects of oil shocks abstract we compare the macroeconomic consequences of several types of oil shocks across a set of industrialized countries that are structurally very diverse with respect to the role of oil and other forms of energy in the economy the results crucially depend on the underlying source of the oil price shift when a rise in oil prices is caused by increased global economic activity or a rise in oil specific demand almost all countries experience respectively a temporary increase and transitory decline of real gdp the role of oil and other forms of energy cannot explain the differences in the effects of both shocks across countries in contrast this role is very important to explain asymmetries in the effects of exogenous oil supply shocks whereas net oil and energy importing countries typically face a permanent fall in economic activity the impact is insignificant or even positive in net energy exporting countries in addition countries that improved their net energy position the most over time became less vulnerable to oil supply shocks relative to other countries

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

price of oil and world inflation and recession new evidence shows that the commonly held assumption that the 1973 74 oil price increase directly affected us and world inflation and subsequent recession is consistent with the empirical data an extended lucas varro real income equation applied to the us united kingdom canada france germany italy japan and the netherlands gives mixed results partly because of price control and decontrol programs simulation experiments on the price control variable using us data finds strong effects further studies can be made when consistent international data is available for the 1979 80 period 18 references 4 figures 3 tables dck

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

firms investment decisions in response to demand and price uncertainty we investigate the effect of demand and price uncertainty on firms planned and realized investment from a panel of manufacturing firms uncertainty measures are derived from firms own expectations about demand and prices and firm s sales we find that demand uncertainty at the time of planning depresses planned and subsequent realized investment firms do not revise their plans due to demand uncertainty at the time of spending suggesting that reducing demand uncertainty will only have lagged effects on investment we do not find any effect of price uncertainty our results are consistent with the behaviour of monopolistic firms with irreversible capital

oil price shocks and stock markets in the u s and 13 european countries abstract oil price shocks have a statistically significant impact on real stock returns contemporaneously and or within the following month in the u s and 13 european countries over 1986 1 2005 12 norway as an oil exporter shows a statistically significantly positive response of real stock returns to an oil price increase the median result from variance decomposition analysis is that oil price shocks account for a statistically significant 6 of the volatility in real stock returns for many european countries but not for the u s increased volatility of oil prices significantly depresses real stock returns the contribution of oil price shocks to variability in real stock returns in the u s and most other countries is greater than that of interest rate an increase in real oil price is associated with a significant increase in the short term interest rate in the u s and eight out of 13 european countries within one or two months counter to findings for the u s and for norway there is little evidence of asymmetric effects on real stock returns of positive and negative oil price shocks for oil importing european countries

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

not all sectors are alike differential impacts of shocks in oil prices on the sectors of the colombian economy abstract in this paper an estimation of differential impacts of shocks in oil prices on the economic sectors in the oil exporting colombia is made using data from the world economy and adopting the model of structural autoregressive vectors var employed by kilian et al 2009 oil prices shocks are estimated according to three types of origin oil supply oil demand and aggregate demand subsequently using data from the colombian economy the effects that these shocks have on sectoral production in colombia are estimated through the use of var models which allow direct impacts to be separated from those that are transmitted through the interrelations between sectors the results obtained show that only the specific demand for oil and aggregate demand shocks affect significantly the total production in colombia although not in all sectors only manufacturing industry and electricity gas and water sectors are directly and significantly affected by both types of demand shocks however when considering the indirect effects transmitted through the interrelations between sectors it was found that the total impacts of these two types of shocks affect the construction transport and trade restaurants and hotels sectors as the effect is positive the colombian economy benefits from increases in oil prices due to demand factors but responds negatively when the opposite situation occurs

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

correlated jumps in crude oil and gasoline during the gulf war this article employs a bivariate poisson jump model to investigate the relationship between the volatility of crude oil and gasoline especially during the period of the gulf war we find that greater jumps occurring in crude oil returns will appear in gasoline returns at the same time but the magnitude of the co movements in volatility falls the covariance is relatively smaller in the second gulf war vs the first conflict the volatility of crude oil is of significantly high levels during periods of the war yet the volatility of gasoline is not as sensitive as crude oil particularly in the second conflict furthermore the jump that occurred by the war did not lead both spot prices to a high persistent level for a long period which fits the feature of the jump models all these findings are important to market traders and hedging strategies

crude oil and stock markets stability instability and bubbles abstract we analyze the long run relationship between the world price of crude oil and international stock markets over 1971 1 2008 3 using a cointegrated vector error correction model with additional regressors allowing for endogenously identified breaks in the cointegrating and error correction matrices we find evidence for breaks after 1980 5 1988 1 and 1999 9 there is a clear long run relationship between these series for six oecd countries for 1971 1 1980 5 and 1988 2 1999 9 suggesting that stock market indices respond negatively to increases in the oil price in the long run during 1980 6 1988 1 we find relationships that are not statistically significantly different from either zero or from the relationships of the previous period the expected negative long run relationship appears to disintegrate after 1999 9 this finding supports a conjecture of change in the relationship between real oil price and real stock prices in the last decade compared to earlier years which may suggest the presence of several stock market bubbles and or oil price bubbles since the turn of the century

separating bric using islamic stocks and crude oil dynamic conditional correlation and volatility spillover analysis abstract this paper explores the dynamic conditional correlation and volatility linkage between islamic indexes and oil for bric countries correlations between these assets increase during the global financial crisis for india and china but not for brazil and russia the volatility error forecast variance of all five indexes comes from spillover but is much lower compared to volatility spillover between conventional indexes and oil hedging performance of islamic indexes are superior in india and china compared to conventional indexes in emerging markets an optimal minimum variance portfolio without reducing expected return can be achieved by investing in lower weights of bric islamic indexes and oil compared to conventional indexes

impact of oil price shocks on output inflation and the real exchange rate evidence from selected asean countries this article analyses the impact of oil price shocks on real output inflation and the real exchange rate in thailand malaysia singapore the philippines and indonesia asean 5 using a structural var model the cointegration tests indicate that the macroeconomic variables of these countries are cointegrated and share common trends in the long run the impulse response functions reveal that oil price fluctuations do not impact the asean 5 economies in the long run and much of its effect is absorbed within five to six quarters the variance decomposition results further assert that with a few exceptions oil price shocks do not explain a significant variation in any of the variables under consideration we also identify a very unique pattern of response to oil price fluctuations between malaysia and singapore and between the philippines and thailand the pairs exhibit a high degree of similarity in their responses they do not share any commonalities across the group

three laws of energy transitions the paper formulates and explores a hypothesis on three general energy transition laws the law of stable long term energy costs to income ratio the law of improving energy quality and the law of growing energy productivity these laws are essential for shaping long term projections and checking for their consistency all three are rooted in amazingly stable in time and universal across countries energy costs to income ratios limited energy purchasing power sets up thresholds which if exceeded bring asymmetry to energy demand to price elasticity the author believes that the theoretical postulate on the substantial substitution among production factors which is used in the production functions theory may be incorrect in reality innovations mainly lead to the substitution of a low quality production factor with the same yet of a better quality improving energy quality with stable costs to income ratio is accompanied by growing energy productivity energy costs to income thresholds are indicators allowing for better projections of oil prices

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

a crude shock explaining the short run impact of the 2014 16 oil price decline across exporters abstract the sharp long lasting decline in oil prices in 2014 16 tested the resilience of oil exporters we examine the degree to which economic fundamentals entering the oil price decline explain the impact on economic growth across oil exporting economies and derive policy implications as to what factors help to mitigate the negative effects we find that pre existing fundamentals account for about half of the cross country variation in the impact of the shock oil exporters that weathered the shock better tended to have a stronger fiscal position higher foreign currency liquidity buffers a more diversified export base a history of price stability and a more flexible exchange rate regime within this group of countries the impact of the shock is not found to be related to the size of oil exports or the share of oil in fiscal revenue or economic activity

the nature of oil shocks and the global economy abstract this paper identifies the main driving force behind oil price shocks in 1970 2006 by applying a simple identification strategy of supply driven and demand driven price shocks the identification hypothesis states that supply driven oil price shocks have a negative impact on the macroeconomic activity of countries which are net consumers of oil while demand driven oil price shocks do not have negative effects in order to identify global demand driven shocks a weighted aggregate gdp series of countries which are net consumers of oil is constructed over 1970 2006 the key result is that the main driving force behind oil price shocks has changed from supply driven shocks in 1970 1992 to demand driven shocks in 1992 2006

asymmetry and uncertainty in capital formation an application to oil investment theories of irreversible investment suggest a negative relation between investment and uncertainty and nonlinear adjustment costs open for asymmetries in the adjustment of fixed capital we propose an econometric modelling approach to estimate and test the key predictions of modern investment theory including asymmetric dynamics and various uncertainty indicators our application on a data set from the oil industry offers empirical support for both asymmetric dynamics and uncertainty in oil and gas investment

economic impacts of higher oil and gas prices the role of international trade for germany the analysis concentrates on direct and indirect price increases induced shifts in international trade and structural changes in the oil importing economies the paper at hand asks whether a stabilizing effect via international trade and domestic structural change on the gdp of oil importing countries can be observed if a permanent oil price increase occurs at least for germany structural change from consumer goods to investment goods industry and an improvement of international competitiveness limit negative impacts of increased energy prices analysis is based on the extensive and disaggregated global ginfors model and the detailed inforge model for the german economy

beyond kyoto backstop technologies and endogenous prices on co2 permits and fossil fuels this paper analyses the markets for fossil fuels given that the limits the kyoto protocol sets on co2 emissions from annex b countries extend beyond 2008 2012 a forward looking model with endogenous prices for fossil fuels is applied under different assumptions concerning the technological progress for a carbon free backstop technology both the time profile of the international permit price needed for the kyoto forever targets as well as the implications through reduced demand and lower producer prices for fossil fuels are calculated the permit price has to rise at least up to 2030 in order to fulfil the emission targets from then on the necessary permit price shows different future developments dependent on when the backstop technology starts to replace oil since changes in the availability of the backstop technology shift the time profile of the permit price the loss of petroleum wealth for oil and gas producers varies between the scenarios but is never more than 20 findings indicate that the

energy price uncertainty energy intensity and firm investment this paper examines the effect of energy price uncertainty on firm level investment an error correction model of capital stock adjustment is estimated with data on u s manufacturing firms higher energy price uncertainty is found to make firms more cautious by reducing the responsiveness of investment to sales growth the result is robust to consideration of energy intensity by industry the effect is greater for high growth firms it must be emphasized that the direct effect of uncertainty is not estimated conditional variance of energy price is obtained from a garch model findings suggest that stability in energy prices would be conducive to greater stability in firm level investment

component based technology transfer in the presence of potential imitators technology transfer to low cost locations offers global firms an opportunity to reduce their variable costs involved in serving emerging markets however such moves may also make imitation by local competitors easier as a consequence technology transfer may create competition in the local market we introduce component based technology transfer for the global firm as a means to deter or accommodate the imitators entry recognizing that components may differ in technological complexity by choosing a subset of components to transfer the global firm s decision has an impact not only on the imitators fixed entry costs but also on postentry competition based on variable costs our research identifies two different types of deterrence strategies the barrier erecting strategy and the market grabbing strategy in the former deterrence strategy the global firm retains enough component technology in the home country to make the potential imitator s fixed entry costs so high that it is not worthwhile entering in the latter deterrence strategy the global firm transfers enough component technology to the emerging market reducing the global firm s variable cost to make the potential imitator s revenues so low that it is not worthwhile entering which deterrence strategy the global firm should employ depends on the degree to which geographical proximity reduces imitation costs and the degree of differentiation between the local firm s and the global firm s products some other interesting and counterintuitive results arise for example it may benefit a global firm to transfer less technology for products with a higher emerging market potential
