oil price cycles and wavelets abstract the present paper addresses the question of the oil price macroeconomy relationship using world data and a time scale decomposition based on the theory of wavelets our approach is based on a global indicator the morgan stanley capital international msci index for the world and on the new framework offered by wavelets to analyse the oil price cycles and to investigate the oil price msci relationship this original approach enables us to identify that the cycles which contribute the most to oil price variations are 20 to 40 years cycles which correspond to the size of kuznets infrastructure cycles and probably represent energy investment cycles this wavelet decomposition also provides additional evidence to the reverse causality theory

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

time variation in the inflation passthrough of energy prices from bayesian estimates of a vector autoregression var which allows for both coefficient drift and stochastic volatility we obtain the following three results first beginning in approximately 1975 the responsiveness of core inflation to changes in energy prices in the united states fell rapidly and remains muted second this decline in the passthrough of energy inflation to core prices has been sustained through a recent period of markedly higher volatility of shocks to energy inflation finally reduced energy inflation passthrough has persisted in the face of monetary policy which quickly became less responsive to energy inflation starting around 1985

exploring the core factors and its dynamic effects on oil price an application on path analysis and bvar tvp model abstract as the uncertainty of oil price increases impacts of the influential factors on oil price vary over time it is of great importance to explore the core factors and its time varying influence on oil price in view of this based on the path analysis model this paper obtains the core factors builds an oil price system var model which uses demand supply price and inventory as endogenous variables and china s net imports as well as dollar index as exogenous variables then we set up a bvar tvp time varying parameter model to analyze dynamic impacts of core factors on oil price the results show that 1 oil prices became more sensitive to oil supply changes and the influence delays became shorter 2 the impact of oil inventories on oil prices with a time lag of two quarters but has a downward trend 3 the impact of oil consumption on oil prices with a time lag of two quarters and this effect is increasingly greater 4 the us dollar index is always the important factor of oil price and its control power increases gradually and the financial crisis occurred in 2008 further strengthens the influence of us dollar

how do oil price shocks affect consumer prices this paper evaluates the degree of pass through from oil price shocks to disaggregate u s consumer prices we find significantly positive effects of the oil price shock only on energy intensive cpis which imply that significantly positive though quantitatively small response of the total cpi is mainly driven by substantial increases in prices of energy related commodities unexpected changes in the oil price may result in decreases in the budget for non energy commodities if the demand for energy is inelastic edelstein and kilian 2009 decreases in the demand for non energy commodities will then result in limited influences on prices of those goods which is consistent with our empirical findings

how robust are popular models of nominal frictions this paper analyzes three popular models of nominal price and wage frictions to determine which best ts post war u s data we construct a dynamic stochastic general equilibrium dsge model and use maximum likelihood to estimate each model s parameters because previous research nds that the conduct of monetary policy and the behavior of in ation changed in the early 1980s we examine two distinct sample periods using a bayesian pseudo odds measure as a means for comparison a sticky price and wage model with dynamic indexation best ts the data in the early sample period whereas either a sticky price and wage model with static indexation or a sticky information model best ts the data in the late sample period our results suggest that price and wage setting behavior may be sensitive to changes in the monetary policy regime if true the evaluation of alternative monetary policy rules may be even more complicated than previously believed

oil price shocks and the macroeconomy this paper examines the impact of oil price shocks and attempts to explain why the rise in oil prices up to 2008 had little impact on the world economy it makes three main arguments first that oil prices have never been as important as is popularly thought second that the most important route through which oil prices affect output is monetary policy when oil prices pass through to core inflation monetary authorities raise interest rates slowing growth based on the second argument the third argument is that high oil prices have not reduced growth in recent years because they no longer pass through to core inflation so the monetary tightening previously seen in response to high oil prices is absent it also argues that oil prices had little impact on the global recession of 20089

energy prices and economic growth in pakistan a macro econometric analysis abstract the paper empirically examines the impact of energy prices on economic growth in pakistan using various channel variables for this purpose a macroeconometric model is estimated using gmm estimation technique using quarterly data for the period 1991 2011 the results indicate that the overall effect of energy prices on growth is negative confirming results from existing empirical literature for pakistan however our methodology allows us to go beyond previous research and describe what drives this overall result we find evidence that high energy price decreases real interest rate investment and stock prices it also decreases the real value of local currency high energy price puts pressure on government expenditures and increases unemployment in the country the results reveal that energy price positively affects output growth through its impact on real interest rate and government consumption while it negatively affects output growth through investment stock prices real exchange rate and unemployment the results show that most of the effect of energy price on economic growth is captured by stock prices real exchange rate government consumption and unemployment in turn real interest rate and investment captures a small effect of energy price on economic growth the study highlights that to improve economic growth policy makers in pakistan should design appropriate policies to control energy prices and to plan energy conservative policies that will motivate to explore alternative energy sources to meet high energy demand in pakistan

the effects of oil price shocks on expenditure category cpi in this study we apply a two block structural vector autoregressive var model proposed by kilian and park 2009 in order to investigate the dynamic effects of changes in oil price on the expenditure category consumer price index cpi in the united states and japan our results confirm that each expenditure category price index responded very differently to the same structural shock and that whether changes in oil price function as a positive stimulus or a negative shock for the individual expenditure category prices also depends on the kind of underlying shock that drives the changes in oil price finally our results also reveal that the manner in which changes in oil price affect each expenditure category price differs between the united states and japan and these detailed level differences may lead to aggregate level differences in the price response of both countries to changes in oil price

dynamic cyclical comovements of oil prices with industrial production consumer prices unemployment and stock prices abstract this paper examines the empirical relationship between oil prices and several key macroeconomic variables in particular we investigate the cyclical comovements of crude oil prices with output consumer prices unemployment and stock prices the methodology involves the use of the hodrick prescott hodrick r j prescott e c 1980 post war us business cycles an empirical investigation working paper carnegie mellon university and baxter king baxter m king r g 1999 measuring business cycles approximate band pass filters for economic time series review of economics and statistics 81 575 593 filters as well as the recently developed full sample asymmetric christiano fitzgerald christiano l j fitzgerald t j 2003 the band pass filter international economic review 44 435 465 band pass filter contemporaneous and cross correlation estimates are made using the stationary cyclical components of the time series to make inference about the degree to which oil prices move with the cycle besides documenting a number of important cyclical relationships using three different time series filtering methods the results suggest that crude oil prices are procyclical and lag industrial production additionally we find that oil prices lead consumer prices

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

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

the impact of oil price shocks on the term structure of interest rates in a structural var framework we study the impact of oil price shocks in the global crude oil market on the dynamics of the entire yield curve in four industrialised countries with different positions on the oil market the us canada norway and south korea responses of the term structure factors to oil market shocks are shown to differ contingent on the underlying sources that drive oil price shocks and the country s dependence on oil oil market specific demand shocks result in increases in the level factor in oil importing countries but have no such effect in oil exporting countries oil supply disruptions have short lived negative responses of the slope factors in the us and canada associated with loosening monetary policy whilst demand side shocks tend to lead to increases the slope in all countries overall oil supply and demand shocks jointly account for a considerable amount of the observed variation in the term structure of interest rates

does gold offer a better protection against losses in sovereign debt bonds than other metals it is a commonly held view that gold protects investors wealth in the event of negative economic conditions in this study we test whether other metals offer similar or better investment opportunities in periods of market turmoil using a sample of 13 sovereign bonds we show that other precious metals palladium in particular offer investors greater compensation for their bond market losses than gold we also find that industrial metals especially copper tend to outperform gold and other precious metals as hedging vehicles and safe haven assets against losses in sovereign bonds however the outcome of the hedge and safe haven properties is not always consistent across the different bonds finally our analysis suggests that copper is the best performing metal in the period immediately after negative bond price shocks

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

trend inflation and monetary policy regimes in japan abstract this paper examines the dynamics of trend inflation in japan over the last three decades based on the smooth transition phillips curve model we find that there is a strong connection between the trend inflation and monetary policy regimes the results also suggest that the introduction of the inflation targeting policy and quantitative and qualitative easing in the beginning of 2013 successfully escaped from the deflationary regime but were not enough to achieve the 2 inflation target finally our results indicate the significance of exchange rates in explaining the recent fluctuations of inflation and the importance of oil and stock prices in maintaining the positive trend inflation regime

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

a model of adjuncts in higher education abstract we examine the phenomenon of the expanded use of non tenure track positions adjuncts and construct a supply side harris todaro model low adjunct wages are attributable to a hope rent from the gap between private opportunities and tenure track utility

low inflation pass through and the pricing power of firms abstract recently there has been a significant decline in the degree to which firms pass through changes in costs to prices a decline that is frequently characterized as a reduction in the pricing power of firms the decline appears to be associated with the decline in inflation in many countries the decline has important implications for monetary policy because it affects both forecasts of inflation and the effects of changes in monetary policy on inflation some have argued that the decline in pricing power helped to keep inflation low in the face of apparently strong demand pressures in the united states in the late 1990s this paper puts forth the view that the decline in pass through or pricing power is due to the low inflation environment that has recently been achieved in many countries first a microeconomic model of price setting is used to show that lower pass through is caused by lower perceived persistence of cost changes evidence is then presented showing that inflation is positively correlated with persistence of inflation suggesting that the low inflation itself has caused the low pass through an economy wide model consistent with the micromodel is then presented to illustrate how such changes in pricing power affect output and inflation dynamics in favorable ways but can disappear quickly if monetary policy and expectations change

oil price fluctuations and singapore economy this study finds that the impact of an oil price shock on the singapore economy is marginal both impulse response and variance decomposition analysis provide reasonable grounds to believe that the impact only had an insignificant adverse effect on singapore s gross domestic product gdp inflation and unemployment rates further analysis on two oil vulnerability measures supports the finding the declining trend of oil intensity in singapore since 1989 and the declining shares of the singapore s expenditure on oil consumption as a percentage of its nominal gdp this study identifies however that the impact of an oil price shock on the singapore economy should not be considered negligible even though it is small

economic growth inflation and oil shocks are the 1970s coming back this article analyses the relationship between oil price shocks and the macroeconomic evolution of the group of seven g7 countries using the qu and perron 2007 methodology we endogenously identify three breaks in the nonlinear relationship across our 1970 to 2008 sample we compute long term multipliers and find that the response of output and inflation to oil price shocks is greatest in the 1970s and progressively disappears until the late 1990s in contrast to the previous literature we observe that both effects reappear in the 2000s especially on inflation nevertheless the transmission of oil price shocks to the economy is weaker than in the 1970s which means that oil price shocks have lost some of their explanatory power precisely identifying these effects is crucial for the design of adequate economic measures to control or smoothen them

inflation targeting during asset and commodity price booms the recent global economic crisis originated in the midst of a commodity price boom that had triggered sharp increases in inflation in many world countries the crisis also came in the context of a rally in asset prices and large domestic imbalances in the united states this paper uses a small open economy dynamic stochastic general equilibrum dsge model to design the correct monetary policy response to a protracted supply shock and examines how that response would change when many become credit constrained like in a credit crunch and when spending of those who can still borrow becomes very sensitive to the interest rates because of overleveraging using a version of the model with kalman learning the paper also evaluates the implications of a loss of target credibility showing how rules must be adjusted when the authorities commitment to the inflation target has been eroded the appropriate response to future evolutions of the price of oil including to large downward corrections from the current level is also evaluated copyright 2010 oxford university press

oil and the euro area economy we examine the macroeconomic effects of different types of oil shocks and the oil transmission mechanism in the euro area a comparison is made with the us and across individual member countries first we find that the underlying source of the oil price shift is crucial to determine the repercussions on the economy and the appropriate monetary policy reaction second the transmission mechanism is considerably different compared to the us in particular inflationary effects in the us are mainly driven by a strong direct pass through of rising energy prices and indirect effects of higher production costs in contrast euro area inflation reacts sluggishly and is much more driven by second round effects of increasing wages the monetary policy reaction of the ecb to oil shocks is also strikingly different compared to the fed the inflation objective relative to the output stabilization objective appears more important for euro area monetary authorities than for the fed third there are substantial asymmetries across member countries these differences are due to different labour market dynamics which are further aggravated by a common monetary policy stance which does not fit all gert peersman and ine van robays

oil price pass through into inflation abstract this paper uses data from 19 industrialized countries to investigate oil price pass through into inflation across countries and over time a time varying pass through coefficient is estimated and the determinants of the recent declining effects of oil shocks on inflation are investigated the appreciation of the domestic currency a more active monetary policy in response to inflation and a higher degree of trade openness are found to explain the decline in oil price pass through

energy sector pricing on the role of neglected nonlinearity modern economies have been subjected to a number of shocks during the past several years such as the burst of the internet bubble terrorist attacks corporate scandals the war in iraq the uncertainty about energy prices and the recent subprime mortgage crisis in particular during the last few years the energy shock has caused concerns for potential stagflation for both the united states and numerous other countries we perform numerous univariate tests for non linearity and chaotic structure using price data from the energy sector to resolve whether the sector s fundamentals or exogenous shocks drive these prices

short and long run asymmetric effect of oil prices and oil and gas revenues on the real gdp and economic diversification in oil dependent economy abstract the aim of this paper is to explore the short and long run asymmetric impact of oil prices shocks and oil and gas revenues changes on the total real gdp and the level of economic diversification of the qatar economy to this end two econometric approaches have been used 1 the a b structural vector autoregressive ab svarx model with exogenous variables where four different asymmetric oil prices and oil and gas revenues measures have been employed and 2 the nonlinear autoregressive distributed lag nardl model the results show that in the short run the responses of both total real gdp and non oil real gdp to negative shocks on real oil prices and real oil and gas revenues are higher than the impact of positive shocks indicating evidence for the existence of asymmetric impact of shocks in the short run however the results suggest that the impact of shocks do not last more than three quarters this evidence for the existence of asymmetric behavior is also confirmed by the nardl analysis which shows that in the long run positive oil prices shocks and oil and gas revenues changes have higher impact on the two proxies of economic activity than negative changes do a result that confirms the resilience of the qatar economy to negative shocks and the positive role played by the energy sector in improving the qatar economic diversification degree finally the results show that the non oil sector is completely resilient to negative shocks in the long run as the impact of negative shocks are insignificant on the non oil real gdp several policies aimed to improve the level of economic diversification of the country and delink the government revenues from oil and gas revenues are proposed and discussed

core inflation and trend inflation abstract this paper examines empirically whether the measurement of trend inflation can be improved by using disaggregated data on sectoral inflation to construct indexes akin to core inflation but with a time varying distributed lags of weights where the sectoral weight depends on the timevarying volatility and persistence of the sectoral inflation series and on the comovement among sectors the modeling framework is a dynamic factor model with time varying coefficients and stochastic volatility as in del negro and otrok 2008 and is estimated using u s data on seventeen components of the personal consumption expenditure inflation index

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

are the macroeconomic effects of oil price shock symmetric a factor augmented vector autoregressive approach abstract this paper aims to examine the asymmetric effect of oil price shocks on real economic activity in the u s within the context of a nonlinear factor augmented vector autoregressive favar model by employing simulation methods we trace the effects of positive and negative oil price shocks on the macroeconomic variables through the impulse response function irf it is found that the negative impacts of higher oil prices are larger than the positive effects of lower oil prices and the asymmetric effects are more evident when the oil price shocks are larger the results are robust to different lag specification and choice of factors

expectations learning and the changing relationship between oil prices and the macroeconomy this paper estimates a structural general equilibrium model to investigate the changing relationship between the oil price and macroeconomic variables the oil price through the role of oil in production and consumption affects aggregate demand and supply in the model the assumption of rational expectations is relaxed in favor of learning oil prices therefore affect the economy through an additional channel i e through their effect on the formation of agents beliefs the estimated learning dynamics indicates that economic agents perceptions about the effects of oil prices on the economy have changed over time oil prices were perceived to have large effects on output and inflation in the 1970s but only milder effects after the mid 1980s since expectations play a large role in the determination of output and inflation the effects of oil price increases on expectations can magnify the response of macroeconomic variables to oil price shocks in the estimated model in fact the implied responses of output and inflation to oil price shocks were much more pronounced in the 1970s than in 2008 therefore through the time variation in the impact of oil prices on beliefs the paper can successfully explain the observed weakening of the effects of oil price shocks on real activity and inflation

linking the gas and oil markets with the stock market investigating the u s relationship energy markets can represent a strategic advantage when they are supporting each other and specifically when energy segments are complementary enough to support economic development and growth in this light a high and strategic interest relies on the possible interactions between energy market segments as well as their impact on a given country s financial market the proposed research focuses on the interaction between the u s natural gas and u s crude oil markets on one side and their dependencies with the u s stock market on the other side after controlling for structural changes or breaks we characterize previous dependencies with the multivariate copula methodology first we assess the joint link prevailing between the natural gas and crude oil markets then we characterize the joint risk structure prevailing between previous energy markets and the u s stock market finally we assess the joint dependence structure between the natural gas crude oil and stock markets

are oil shocks inflationary asymmetric and nonlinear specifications versus changes in regime this paper identifies a structural break in core u s inflation phillips curves such that oil prices contributed substantially before 1981 but since that time pass through has been negligible this characterization is robust to a variety of re specifications and fits the data better than asymmetric and nonlinear oil price alternatives evidence does not support the hypotheses that declining energy intensity or deregulation of energy producing and consuming industries played an important role monetary policy did not itself become less accommodative of oil shocks but may have helped create a regime where inflation is less sensitive to price shocks more generally

another pass through bites the dust oil prices and inflation el presente articulo presenta evidencia de que el traspaso de los movimientos del precio del petroleo al nivel general de precios ha disminuido en forma importante en las ultimas decadas se encuentra que tal disminucion es generalizada para un amplio conjunto de paises luego de documentar correlaciones entre el indice de precios al consumidor y el precio del petroleo se utilizan dos estrategias de estimacion en un intento por identificar adecuadamente el efecto inflacionario de los shocks del petroleo primero se estima la curva de phillips tradicional para 34 paises aumentada de modo de incluir el petroleo y testear si existe quiebre estructural esta metodologia muestra una caida en el traspaso medio estimado para los paises industrializados y en menor medida para las economias emergentes segundo se estiman vectores autorregresivos en ventanas moviles para una submuestra de paises para los que existen datos suficientes se derivan funciones de impulso respuesta de la inflacion a los shocks petroleros y se interpretan las integrales como estimaciones del traspaso se encuentra que el efecto de los shocks petroleros sobre la inflacion se ha reducido en la mayoria de los doce paises de la muestra entre los factores que podrian explicar esta caida en nuestra opinion los mas importantes son que la intensidad economica del petroleo se ha reducido en el mundo que tambien ha disminuido el traspaso del tipo de cambio que el ambiente inflacionario es mas favorable y que el actual shock del precio del petroleo es el resultado de una solida demanda mundial estos factores ayudan a entender no solo por que el actual shock ha tenido efectos inflacionarios limitados sino asimismo por que sus consecuencias en el producto tambien han sido limitadas

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

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

how is volatility in commodity markets linked to oil price shocks abstract this study investigates the effects of oil price shocks on volatility of agricultural and metal commodities we decompose an oil price shock to its underlying components including macroeconomics and oil specific shocks the applied method is the structural vector autoregressive svar model and the time span is from april 1983 to may 2014 the investigation is divided into two subsamples before and after may 2006 for agriculture taking into account the 2006 2008 food crisis and change in u s ethanol production policy and before and after january 2008 for metals considering the recent global financial crisis we find that based on impulse response functions the response of volatility of each commodity to an oil price shock differs significantly depending on the underlying cause of the shock for the both periods moreover according to variance decomposition the explanatory power of oil shocks becomes stronger after the crisis the different responses of commodities are described in detail by investigating market characteristics in each period

the impact of oil shocks on the spanish economy abstract this paper analyses the impact of oil price shocks on both the gdp growth and on inflation in the economy of spain and its seventeen regions the qu and perron 2007 and the bai and perron 1998 2003a and 2003b methods identify different periods across the sample evidence of a diminishing effect of oil price shocks on gdp growth and on inflation is found from the 1970s until the mid 1980s however in contrast with previous literature we find a renewed effect on both these macroeconomic variables after the mid 80s in spain it recovers some of its initial importance in the second half of the 1990s for gdp and between 1986 and 1994 and the 2000s for inflation in the regions the influence of oil price shocks on the gdp progressively disappears while the impact on inflation decreases from 1986 onwards but becomes significant again ten years later the most outstanding result is that oil price movements explain at least some of the recent inflation therefore policy measures to control the economic impact of oil shocks should be implemented in the future

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

core and crust consumer prices and the term structure of interest rates we propose a model for nominal and real term structures of interest rates that includes dynamics for the three main components of total inflation core food and energy these dynamics combine together to produce a measure of expected total inflation that investors use to price nominal treasuries this framework captures different frequencies in inflation fluctuations shocks to core are more persistent and less volatile than shocks to food and especially energy the crust we find that a common structure of latent factors determines and predicts the term structure of yields and inflation our model outperforms popular benchmarks e g arma var and random walk specifications and it is at par with the survey of professional forecasters in forecasting inflation moreover we estimate real rates that agree with inflationindexed bond yields after adjusting for the liquidity premium in these bonds finally inflation and real rate risk premia show a declining pattern consistent with the changing nature of inflation and real rate risks

long run economic performance and the labor market 1 introductionthis article studies growth when the economy is not using all its productive resources to establish a bridge among two subdisciplines in economics growth theory and unemployment theory the former is dynamic and considers the impact on output of the growth in inputs under the assumption that unemployment is nonexistent the latter is static and considers the determination of the rate of unemployment under the assumption that the growth of capital is nonexistent our goal herein is twofold on one hand we want to modify slightly the growth models to include the effects of persistent unemployment on long run growth on the other we want to analyze the role played by the accumulation of capital in determining the unemployment rate the underlying assumption in the neoclassical growth model is that even if we admit sticky wages in the short run in the long run the labor market should have time to clear and the economy should return to full employment understood as the level of employment compatible with frictional unemployment therefore what is relevant when talking about growth is the growth of the labor force not the growth of the employed labor force however if the equilibrium employment level in the labor market persistently differs from the more desirable frictional level it is conceivable that this persistent deviation will have an impact on long run growth the average u s unemployment rate during the 1990s was 5 8 while countries such as france and spain maintained double digit unemployment rates in the 1980s and 1990s it seems intuitive that double digit unemployment during two decades should have long lasting effects on standards of living the disparate experiences of some european countries as opposed to the united states in terms of employment rates are due to very different institutional factors in the corresponding labor markets this article studies the impact of labor market institutional variables on long run growth despite a very large literature on both growth and unemployment few papers have jointly studied these two phenomena the exceptions are furuya 1998 and daveri and tabellini 2000 daveri and tabellini study the implications of an increase in labor taxes on both unemployment and economic growth the models in these two papers are of the overlapping generation class but whereas in furuya s the labor market does not clear because of the existence of efficiency wages in daveri and tabellini s the labor market does not clear because of the existence of a union our model is a simple variation of the standard solow model suitable for a first approximation to an empirical investigation of the interrelationship between economic growth and the labor market we use a variation of blanchflower and oswald s 1995 wage curve which is more suitable for integration with a growth model the wage curve shows an empirical inverse relation between unemployment and wage levels this inverse relation is consistent with models of noncompetitive wage determination basically we use a reduced form of the open trade union layard nickell layard and nickell 1985 1986 model of wage determination to explain why the equilibrium unemployment level differs from the frictional level a weakness of relying on trade union behavior to explain unemployment is that in most countries not all workers are unionized union membership varies greatly across countries but in most countries a large part of the labor force is nonunionized however blanchard and summers 1986 argue that the trade union model can be interpreted as describing the behavior of a group of workers that acts as a group even if there is no formal trade union the fact that both capital intensity and productivity affect the equilibrium unemployment rate is implicit in the layard nickell model we emphasize the importance of capital intensity in the determination of unemployment and incorporate unemployment into a growth model

on the dynamic links between commodities and islamic equity abstract this paper investigates whether commodities offer potential diversification benefits for islamic equity index investors in light of possible financialization of commodity markets using mgarch dcc and wavelet coherence analyses our findings reveal that correlations between commodity markets and the dow jones islamic market world index are time varying and highly volatile throughout the january 1999 april 2015 period a substantial and persistent increase was observed in the return correlations between commodities and islamic equity at the onset of the 2008 financial crisis however trends in the recent two years suggest that this association is heading towards its pre crisis levels offering again diversification benefits for islamic equity holders these benefits vary across different commodities in various time scales overall gold natural gas soft commodities grains and livestock are better portfolio diversifiers than oil and other metals relative to medium to long term investors short term investors less than 32 days horizon gained better diversification benefits in most commodities during bullish bearish and market recovery periods these findings have implications for investors who are heterogeneous in risk tolerance and time preference as well as for policymakers who are concerned with market stability

the impact of oil price shocks in the canadian economy a structural investigation on an oil exporting economy abstract oil price shocks and monetary policy response by oil producing economies have been the subject of important theoretical investigation in the modern literature this topic seems to be well grounded since fluctuations in the us dollar which is affected by us monetary policy plays an important role in exacerbating run ups and precipitous falls in world oil prices we investigate the economic consequences of oil price shocks using an open economy dsge model that incorporates demand for and supply of oil while allowing for interaction between domestic and foreign monetary policy using canadian and u s data we quantify the relative importance of oil price shocks and monetary policy response on macroeconomic variables we show that domestic monetary policy is a key channel that accounts for over 40 of discounted variation in domestic output across a 4 year horizon after an oil shock in contrast us monetary policy is of lesser importance in propagating oil price shocks on an oil exporting economy through the international channel

connectionist based rules describing the pass through of individual goods prices into trend inflation in the united states this paper demonstrates a mechanism whereby rules can be extracted from a feedforward neural network trained to characterize the inflation pass through problem in american monetary policy defined as the relationship between changes in the growth rate s of individual commodities and the economy wide rate of growth of consumer prices monthly price data are encoded and used to train a group of candidate connectionist architectures one candidate is selected for rule extraction using a custom decompositional extraction algorithm that generates rules in human readable and machine executable form rule and network accuracy are compared and comments are made on the relationships expressed within the discovered rules the types of discovered relationships could be used to guide monetary policy decisions

energy consumption and gdp revisited a panel analysis of developed and developing countries this paper applies a new panel data stationarity testing procedure first developed by carrion i silvestre et al 2005 econometrics journal 8 159 175 with panel vars that employ the generalized method of moment techniques in order to re investigate the dynamic interactions between energy consumption per capita lec and real gdp per capita lry in 22 developed and 18 developing countries when multiple breaks in the series are taken into account there is convincing evidence of panel stationarity for lec and lry in both groups the energy crises evidently had a substantive impact on both lec and lry in all sample countries furthermore our panel vars attest to bidirectional causality between lec and lry in developed countries but there is uni directional causality from lry to lec in developing countries finally from the orthogonalized impulse response functions all of the variables in the panel vars have a positive effect on each other but their impact is greater and more persistent in developing countries some important policy implications do emerge

the impact of natural gas price control in china a computable general equilibrium approach abstract this paper depicts the natural gas price control behavior of the chinese government in an imperfect competition market structure using a static cge model it simulates the effect of changes in natural gas price control policy on carbon emission and the economic effects in view of demand side and supply side based on the above we also analyze the carbon emission mechanism from economic and energy structure perspective the results show that an increase in natural gas price can reduce carbon emission or tends to cause a long term decline in the surplus profit rate of the natural gas industry moreover the increase in natural gas price may raise the cpi and reduce actual gdp and residents welfare on the contrary a decrease in natural gas price may reduce cpi and enhance resident welfare however the long term actual gdp will not increase but carbon emission will increase and the surplus profit rate of the natural gas industry may reduce in the short term and increase in the long term on the other hand both increase and decrease in natural gas prices may result in a decrease of the actual gdp level in the long term the elimination of price control in natural gas supply may increase actual gdp and residents welfare and reduce cpi meanwhile it may increase carbon emissions and improve the profitability of the natural gas industry

commodity prices convenience yields and inflation abstract this paper provides evidence that the two leading principal components in a panel of 23 commodity convenience yields have statistically and quantitatively important predictive power for inflation even after controlling for unemployment gap and oil prices the results hold up in out of sample forecasts across forecast horizons and across g7 countries the convenience yields also explain commodity prices and can be seen as informational variables about future economic conditions as conveyed by the futures markets a bootstrap procedure for conducting inference when the principal components are used as regressors is also proposed

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

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

inflation target and a symmetries in the oil price pass through to inflation in this paper we employ state space models to estimate the pass through of oil price changes to consumer prices for a large sample of countries from 1970 to 2017 by controlling for self selection bias and endogeneity and allowing for different responses to positive and negative price changes we asses the differences between explicit inflation targeting it countries and a control group surprisingly perhaps our results suggest that the pass through is higher for it countries our main contribution is to show that these is mainly due to it countries having a significant higher pass through than non it countries when the oil price decreases a 10 drop in oil price leads about a 0 11 drop in inflation in iters of which 4pp are explained by the monetary regime importantly we show that adopting it reduces the asymmetry of the pass through we run several robustness checks and conclude that falling oil prices are more welcomed by the central banks with an it framework in particular during deflationary episodes or when inflation is above the target jel classification e31 e42 q43

structural breaks energy consumption and economic growth revisited evidence from taiwan abstract this paper studies the stability between energy consumption and gdp for taiwan during 1954 2003 we use aggregate as well as various disaggregate data of energy consumption including coal oil gas and electricity to employ the unit root tests and the cointegration tests allowing for structural breaks our main findings are first though gas consumption seems to have structural breaks in the 1960s after considering the structural breaks the series is a stationary variable when taiwan adopted its expansionary export trade policy second we find that different directions of causality exist between gdp and various kinds of energy consumption the empirical result shows unanimously in the long run that energy acts as an engine of economic growth and that energy conservation may harm economic growth third the cointegration between energy consumption and gdp is unstable and some economic events may affect the stability overall we do find the structural breakpoints and they look to match clearly with the corresponding critical economic incidents

regime switching model of us crude oil and stock market prices 1859 to 2013 this paper examines the relationship between us crude oil and stock market prices using a markov switching vector error correction model and a monthly data set from 1859 to 2013 the sample covers the entire modern era of the petroleum industry which typically begins with the first drilled oil well in titusville pennsylvania in 1858 we estimate a two regime model that divides the sample into high and low volatility regimes based on the variance covariance matrix of the oil and stock prices we find that the high volatility regime more frequently exists prior to the great depression and after the 1973 oil price shock caused by the organization of petroleum exporting countries the low volatility regime occurs more frequently when the oil markets fell largely under the control of the major international oil companies from the end of the great depression to the first oil price shock in 1973 using the national bureau of economic research business cycle dates we also find that the high volatility regime more likely occurs when the economy experiences a recession

slow oil shocks and the weakening of the oil price macroeconomy relationship abstract many papers have been documenting and analysing the asymmetry and the weakening of the oil price macroeconomy relationship as off the early eighties while there seems to be a consensus about the factors causing the asymmetry namely adjustment costs which offset the benefits of low energy prices the debate about the weakening of the relationship is not over yet moreover the alternative oil price specifications which have been proposed by mork 1989 lee et al 1995 and hamilton 1996 to restore the stability of the relationship fail to granger cause output or unemployment in post 1980 data by using the concept of accelerations of the oil price we show that the weakening of this relationship corresponds to the appearance of slow oil price increases which have less impact on the economy when filtering out these slow oil price variations from the sample we manage to rehabilitate the causality running from the oil price to the macroeconomy and show that far from weakening the oil price accelerations gdp relationship has even been growing stronger since the early eighties

how does coal price drive up inflation reexamining the relationship between coal price and general price level in china abstract due to the coal dominated energy structure china is currently facing significant economic uncertainties brought forward by instability of coal price by separating the asymmetric effects that how upward and downward coal price changes pass through to the economy this paper reexamines the relationship between coal price and general price level in china the asymmetric effects are investigated via vector autoregression models granger causality tests and impulse response function analyses using the monthly time series data from jun 98 to sep 14 results show negative coal price change presents more significant impact on inflation than positive one the inflation responses very abruptly to coal price shock in the short run but the impact regresses rapidly along time accumulatively a 1 increase of coal price will push cpi and ppi up by 0 04 and 0 12 while a 1 decrease of coal price will pull them down by 0 08 and 0 17 respectively the linkage among coal price change ppi and cpi is demonstrated as the main transmission channel of price shock the inflationary effect is strong in the initial stage but will be weakened in the later stage since the pass through effect from ppi to cpi is tiny which confirms ppi is more responsive than cpi to coal price change for policy implications how to avoid extreme volatility in general price level is a major concern of recent agendas such as reforming energy market and building green fiscal system

assessing the impact of oil prices on firms of different sizes its tough being in the middle recent empirical research has found evidence of a relationship between oil price movements and stock prices most published research investigates the relationship between oil price movements and stock prices using either economy wide measures of stock prices or industry sector measures of stock prices an important question that has largely gone unanswered relates to the relationship between oil prices and stock prices when the size of firms is allowed to vary relative to large firms do oil price movements have larger or smaller impacts on the stock prices of small or medium sized firms the answer to this question could have important policy implications that affect economic growth and prosperity in this paper a panel of firms is followed over a 17 year period to investigate the relationship between oil price movements firm size and stock prices evidence is found that shows the relationship between oil price movements and stock prices does vary with firm size and the relationship is strongest for medium sized firms

what is the globalisation of inflation abstract this paper studies the globalisation of cpi inflation by analysing core energy and food components testing for structural breaks in the relationships between domestic inflation and a corresponding country specific foreign inflation series at the monthly frequency for oecd countries the iterative methodology employed separates coefficient and variance breaks while also taking account of outliers we find that the overall pattern of globalisation in aggregate inflation is largely driven by convergence of the mean levels of the core component from the early 1990s compatible with the introduction of inflation targeting in many countries of our sample there is less evidence of increased synchronisation of shortrun movements in core than aggregate inflation but an increased role for shortrun foreign energy inflation often contributes to the globalisation effect

dynamic effects of rising oil prices on consumer energy prices in canada and the united states evidence from the last half a century abstract this paper examines the dynamic relationship between the price of crude oil and the cpi energy price sub index in canada and the u s using a markov regime switching model and the bai perron sequential method since these two series are cointegrated during the sample period january 1961 june 2013 a short run dynamic model is thus estimated for each country in which all coefficients and the error variance terms can freely switch over time between two values prevailing in regimes 0 and 1 previous studies indicate that the price of crude oil does not currently affect the aggregate cpi as much as it did in the 1970s this finding is not disputed in this paper however the sequentially determined break date as well as the time varying regime switching probabilities point to two new findings first the marginal effects of changes in oil price on consumer energy prices not the aggregate cpi have consistently increased and become more instantaneous for both countries after the western u s energy crisis of 2000 second the speed of adjustment proxied by different error correction coefficients has also risen particularly for the u s therefore oil prices exert far more positive and immediate impacts on energy costs in the post rather than pre 1999 periods

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

precious metals oil and the exchange rate contemporaneous spillovers abstractwe investigate the contemporaneous spillovers among precious metals crude oil and the us exchange rate we contend that conventional reduced form vector autoregressive var models based on lead lag relations do not fully capture the interactions among these series as these models ignore the contemporaneous effects using a structural var model we identify these contemporaneous spillovers which are shown to be strong and asymmetric we further show that not taking into consideration the contemporaneous interactions among these assets leads to inaccurate findings and inevitably to inaccurate interpretations of the causal relations among them

advancing the design of a dynamic petro dollar currency basket this study offers organization of petroleum exporting countries opec member nations a crude oil pricing currency basket based on currency liquidity in contrast with prior emphasis on opec trading patterns motivating the search for an alternative us dollar pricing of crude oil is the significant and inverse relationship r 0 82 p 0 01 between the us dollar major currencies index and crude oil price over the period january 1999 march 2009 a dynamically weighted petro dollar currency basket is proposed based on the five currency claims us dollar euro british pound japanese yen and swiss franc and their varying proportions of foreign exchange reserves held by central banks the major currencies us dollar index is compared against the proposed petro dollar index to reveal an average us 8 1 billion annual gain in favor of the petro dollar currency basket offering opec members a revenue stream of diversified and highly liquid currencies to transition away from complete dependence on the us dollar crude oil pricing the proposed petro dollar crude oil pricing schema offers opec a crude oil price dynamically denominated in currencies reflecting the global use and importance of crude oil this paper concludes with implementation issues facing a move toward the dynamically weighted petro dollar crude oil pricing schema

the nairu unemployment and monetary policy this paper examines the precision of conventional estimates of the nairu and the role of the nairu and unemployment in forecasting inflation the authors find that although there is a clear empirical phillips relation the nairu is imprecisely estimated forecasts of inflation are insensitive to the nairu and there are other leading indicators of inflation that are at least as good as unemployment this suggests deemphasizing the nairu in public discourse about monetary policy and instead drawing on a richer variety of leading indicators of inflation

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
