the importance of managerial ability on crude oil price uncertainty firm performance relationship abstract this paper investigates the effect of crude oil price uncertainty on firm performance and how the managerial ability impacts on this relationship using a large sample of 13 610 u s firms from 1983 to 2016 we reveal two main findings consistent with our hypothesis we find strong evidence for a negative effect of crude oil price uncertainty on firm performance at both aggregate market and sectoral levels however managerial ability helps firms dampen a significant proportion approximately 20 50 of the negative effect these findings are consistent in several robustness tests

on the impacts of oil price fluctuations on european equity markets volatility spillover and hedging effectiveness the objective of this paper is to investigate the volatility spillovers between oil and stock markets in europe as not all industries are expected to be equally affected by oil price changes we conduct our study at both the aggregate as well as sector levels empirically we make use of a recently developed var garch approach which allows for transmissions in volatilities in addition we analyze the optimal weights and hedge ratios for oil stock portfolio holdings based on our results on the whole our findings show significant volatility spillovers between oil price and sector stock returns and suggest that a better understanding of those links is crucial for portfolio management in the presence of oil price risk

oil price volatility and stock price fluctuations in an emerging market evidence from south korea abstract how important are oil price fluctuations and oil price volatility on equity market performance what are the policy implications if volatility turns out to be significant we assess this issue in an economics finance nexus for korea using a vec model including interest rates economic activity real stock returns real oil prices and oil price volatility our main aim is to capture the effects of crude oil prices on the korean economy thoroughly covering the period of the asian financial crisis of 1997 which heavily affected the country and the oil price hikes in the early 1990s after the gulf war south korea was the country most hit by the financial crisis together with indonesia and thailand results indicate the dominance of oil price volatility on real stock returns and emphasize how this has increased over time oil price volatility can have profound effect on the time horizon of investment and firms need adjust their risk management procedures accordingly this increase in dependency has been found in other net oil importing emerging equity markets we test the relationship between oil price movements and economic activity by using modern time series techniques in a cointegrating framework we expand the standard error correction model by examining the dynamics of out of sample causality through the generalized variance decomposition and impulse response function techniques the evidence from persistence profiles also gives important guidelines based on how fast the entire system adjusts back to equilibrium in addition we find the cointegrating relationship to be stable and find that the linear error correction model to be more favorable than an asymmetric 2 period markov switching model

oil prices and the stock prices of alternative energy companies energy security issues coupled with increased concern over the natural environment are driving factors behind oil price movements while it is widely accepted that rising oil prices are good for the financial performance of alternative energy companies there has been relatively little statistical work done to measure just how sensitive the financial performance of alternative energy companies are to changes in oil prices in this paper a four variable vector autoregression model is developed and estimated in order to investigate the empirical relationship between alternative energy stock prices technology stock prices oil prices and interest rates our results show technology stock prices and oil prices each individually granger cause the stock prices of alternative energy companies simulation results show that a shock to technology stock prices has a larger impact on alternative energy stock prices than does a shock to oil prices these results should be of use to investors managers and policy makers

how do u s stock returns respond differently to oil price shocks pre crisis within the financial crisis and post crisis abstract we use a long time series of daily data for 682 firms over a period from january 1990 to december 2012 each firm includes 5 772 daily observations our sample involves a total of 3 936 504 observations to investigate how u s stock returns respond differently to oil price shocks prior to during and after a financial crisis we provide evidence that u s stock returns in turn respond positively to the changes in oil prices during and after such a crisis we use firm level data to find that positive and negative oil price shocks have asymmetric effects on stock returns during the crisis and after the crisis then we examine whether the effect of an oil price shock on stock returns varies across oil intensive industries within the crisis and post crisis our results indicate that stock returns in response to oil price shocks across industries are heterogeneous and the stock returns of some energy intensive manufacturing industries respond more positively to oil price shocks compared with less energy intensive manufacturing industries we use total assets total revenue and the number of employees as proxy variables to measure each firm s size and then examine whether oil price shocks affect stock returns differently across firm sizes we find that big firms are the most strongly and negatively influenced by an oil price shock prior to the crisis on the other hand our results indicate that an oil price shock in the post financial crisis period is positively amplified in the case of medium sized firms

the effects of oil price uncertainty on global real economic activity this paper investigates the effect of oil price uncertainty on global real economic activity using a quarterly vector autoregressive model with stochastic volatility in mean stochastic volatility allows oil price uncertainty to vary separately from changes in the level of oil prices and allows one to incorporate an extraneous indicator of oil price uncertainty such as realized volatility that greatly improves the precision of the estimated uncertainty series the estimation results show that an oil price uncertainty shock has negative effects on world industrial production all else equal for example it is shown that a doubling of oil price volatility is associated with a cumulative decline as high as 0 3 percentage points in world industrial production

does oil move equity prices a global view many studies indicate that oil price shocks have an adverse effect on real output and hence an adverse effect on corporate profits where oil is used as a key input the present study examines whether and to what extent the adverse effect of oil price shocks impacts stock market returns to this end we analyse 35 datastream global industry indices for the period from april 1983 to september 2005 our findings indicate that oil price rises have a negative impact on equity returns for all sectors except mining and oil and gas industries generally these results are consistent with economic theory and evidence provided by previous empirical studies little evidence of any asymmetry is detected in the oil price sensitivities in light of our findings we recommend that international portfolio investors consider hedging oil price risk

firm valuation earnings expectations and the exchange rate exposure effect consistent with previous research we fail to find a significant correlation between the abnormal returns of our sample firms with international activities and changes in the dollar we investigate the possibility that this failure is due to mispricing lagged changes in the dollar are a significant variable in explaining current abnormal returns of our sample firms suggesting that mispricing does occur a simple trading strategy based upon these results generates significant abnormal returns corroborating evidence from returns around earnings announcements as well as errors in analysts forecasts of earnings is also provided it is a widely held view that exchange rate movement should affect the value of a firm standard economic analysis implies that the profitability and value of most u s firms with foreign sales or operations abroad should increase decrease with an unexpected depreciation appreciation of the dollar as expected foreign currency cash flows translate into larger smaller u s

oil price shocks economic policy uncertainty and industry stock returns in china asymmetric effects with quantile regression abstract this paper investigates the impact of crude oil shocks and china s economic policy uncertainty on stock returns at different locations on the return distributions based on monthly data from 1995 1 to 2016 3 we address this issue by employing the quantile regression technique this approach enables a more detailed investigation in different market circumstances namely bearish normal and bullish markets empirical results indicate that the effects of oil price shocks and economic policy uncertainty are asymmetric and highly related to stock market conditions moreover both the nexus of oil and economic policy uncertainty stock are changed at the onset of a crisis specially rising oil prices have greater negative effects on stock returns when stock markets are bullish extreme higher quantiles before a crisis whereas the effects are significantly positive under different market conditions after the onset of the crisis falling oil prices lower stock returns when stock markets are bullish and normal before the crisis whereas lower stock returns under different market conditions except extreme bullish after the onset of the crisis these findings might be related to the optimistic or pessimistic investor sentiments and investors might become more frightened after the crisis

do structural oil market shocks affect stock prices abstract this paper investigates how explicit structural shocks that characterize the endogenous character of oil price changes affect stock market returns in a sample of eight countries australia canada france germany italy japan the united kingdom and the united states for each country the analysis proceeds in two steps first modifying the procedure of kilian kilian l forthcoming not all oil price shocks are alike disentangling demand and supply shocks in the crude oil market american economic review we employ a vector error correction or vector autoregressive model to decompose oil price changes into three components oil supply shocks global aggregate demand shocks and global oil demand shocks the last component relates to specific idiosyncratic features of the oil market such as changes in the precautionary demand concerning the uncertainty about the availability of future oil supplies second recovering the oil supply shocks global aggregate demand shocks and global oil demand shocks from the first analysis we then employ a vector autoregressive model to determine the effects of these structural shocks on the stock market returns in our sample of eight countries we find that international stock market returns do not respond in a large way to oil market shocks that is the significant effects that exist prove small in magnitude

regional and copula estimation effects on eu and us energy equity portfolios the aim of this paper is to investigate the regional interdependence structure of energy equities in the us and in the eu based on weekly stock prices of 28 big energy firms in the two regions fro

modelling oil price volatility with structural breaks in this paper we provide two main innovations i we analyze oil prices of two prominent markets namely west texas intermediate wti and brent using the two recently developed tests by narayan and popp 2010 and liu and narayan 2010 both of which allow for two structural breaks in the data series and ii the latter method is modified to include both symmetric and asymmetric volatility models we identify two structural breaks that occur in 1990 and 2008 which coincidentally correspond to the iraqi kuwait conflict and the global financial crisis respectively we find evidence of persistence and leverage effects in the oil price volatility while further extensions can be pursued the consideration of asymmetric effects as well as structural breaks should not be jettisoned when modelling oil price volatility

costly external finance corporate investment and the subprime mortgage credit crisis abstract we study the effect of the recent financial crisis on corporate investment the crisis represents an unexplored negative shock to the supply of external finance for non financial firms corporate investment declines significantly following the onset of the crisis controlling for firm fixed effects and time varying measures of investment opportunities consistent with a causal effect of a supply shock the decline is greatest for firms that have low cash reserves or high net short term debt are financially constrained or operate in industries dependent on external finance to address endogeneity concerns we measure firms financial positions as much as four years prior to the crisis and confirm that similar results do not follow placebo crises in the summers of 2003 2006 nor do similar results follow the negative demand shock caused by september 11 2001 the effects weaken considerably beginning in the third quarter of 2008 when the demand side effects of the crisis became apparent additional analysis suggests an important precautionary savings motive for seemingly excess cash that is generally overlooked in the literature

nonparametric panel data model for crude oil and stock market prices in net oil importing countries abstract this paper introduces an innovative nonparametric panel data approach to model the long run relationship between the monthly oil price index and stock market price indices of ten large net oil importing countries namely the united states japan china south korea india germany france singapore italy and spain in the proposed model we allow the coefficient on the oil price index to be a time varying function which evolves over time in a way that is assumed to be unknown we also allow the common trend function to evolve over time as well as extending the model further to incorporate country specific trend functions we employ a data driven local linear method to estimate these time varying trend and coefficient functions the results show that despite being largely positive there are several downward trends reflecting the aftermath of the iraq war and the recent unprecedented drop in the oil price overall we find that the nonparametric panel data model better captures the way in which the underlying stock oil price relationship has evolved over time in comparison to the point estimates of the parametric counterpart moreover we find that stock market fundamentals play a significant role in determining the oil stock price relationship our findings have important implication for policymakers and financial speculators

the effect of oil price volatility on strategic investment in this paper we investigate how oil price volatility affects the strategic investment decisions of a large panel of us firms this paper uses key insights from the real options literature to develop a model of a company s strategic investment and shows how changes in oil price volatility can impact strategic investment decisions the model is estimated using recently developed generalized method of moment estimation techniques for panel data sets empirical results are presented to show that there is a u shaped relationship between oil price volatility and firm investment this is consistent with the predictions from the strategic growth options literature the results should be useful to decision makers investors managers policy makers and others who need to make strategic investment decisions in an uncertain world

where to place the saving obligation energy end users or suppliers abstract obligations to save energy differentiate among other features by obliged parties these are obligations on energy suppliers and energy end users supplier obligations have been introduced in north america europe and australia under supplier obligations energy suppliers have to comply with mandatory energy saving targets and thus they implement directly or via third parties energy efficiency projects on their clients premises or they decide to trade certified project savings if this option is envisaged by their obligation scheme in several emerging schemes such as the uk carbon reduction commitment crc energy efficiency scheme the tokyo emission trading scheme or the perform achieve and trade pat scheme in india the obligation to reduce energy consumption is placed on large end users directly and end users are allowed to trade emissions allowances or energy saving certificates the paper starts with presenting these two conceptually different ways for introducing energy saving obligations then it analyses advantages and disadvantages of end users obligations compared to suppliers obligations the preliminary conclusion of the paper is that supplier obligations seem to be well suited for the residential sector but end user saving obligations may offer advantages when it comes to the industrial and commercial sectors

exchange rate exposure and industry characteristics evidence from canada japan and the usa abstract this paper examines industry level exchange rate exposures for canada japan and the usa measuring exposure by adding the change in the exchange rate to the domestic market model of industry portfolio returns some industries in all three countries display significant exposures moreover for each country the exchange rate is important for explaining industry returns at the economy wide level to explore whether exchange rate exposures are systematically linked to the activities of the industries we model exposure as a function of industry characteristics for all three countries the relation between exposure and industry characteristics is broadly consistent with economic theory jel f3

how do great shocks influence the correlation between oil and international stock markets abstractwe investigate the impacts of great shocks 2003 iraq war and 2008 financial crisis on the correlations between oil and us china stock markets utilizing a novel madcc mixed asymmetry dynamic conditional correlation model this model successfully captures the coexistence of opposite signed asymmetries we find that great shocks indeed increased the correlations further results from the news impact surfaces indicate that correlations between oil and stock markets are higher to joint negative shocks however correlation between stock markets has stronger response to joint positive shocks

a lagrange multiplier test for causality in variance we adapt the lagrange multiplier lm principle to test for noncausality in variance of financial returns the new test is compared with a portmanteau statistic cheung y w ng l k 1996 a causality in variance test and its application to financial market prices journal of econometrics 72 33 48 a monte carlo study reveals superior power of the lm test

volatility behavior of oil industrial commodity and stock markets in a regime switching environment abstract this study supplements previous regime switching studies on wti crude oil and finds two possible volatility regimes for the strategic commodity prices of brent oil wti oil copper gold and silver and the s p 500 index but with varying high to low volatility ratios the dynamic conditional correlations dccs indicate increasing correlations among all the commodities since the 2003 iraq war but decreasing correlations with the s p 500 index the commodities also show different volatility persistence responses to financial and geopolitical crises while the s p 500 index responds to both financial and geopolitical crises implications are discussed

an empirical investigation of the relative performance evaluation hypothesis the principal agent framework has become a widely used paradigm in accounting and economics for analyzing issues in performance evaluation management control and the design of incentive systems while recent work in experimental economics has begun to examine empirically some of the underlying assumptions and implications of agency theory see baiman and lewis 1989 and kirby forthcoming few precise hypotheses have been tested using real world or naturally occurring data one exception has been the empirical investigation of the relative performance evaluation rpe hypothesis agency theory suggests that there are benefits associated with evaluating agents on the basis of their relative performances when the agents performances are affected by a common shock term e g see diamond and verrecchia 1982 and holmstrom 1979 1982 specifically a relative performance based contract can remove the common shock term from an agent s performance which enables a better evaluation of the agent s actions

jevons paradox revisited the evidence for backfire from improved energy efficiency beginning with william stanley jevons in 1865 a number of authors have claimed that economically justified energy efficiency improvements will increase rather than reduce energy consumption jevons paradox is extremely difficult to test empirically but could have profound implications for energy and climate policy this paper summarises and critiques the arguments and evidence that have been cited in support of jevons paradox focusing in particular on the work of len brookes and harry saunders it identifies some empirical and theoretical weaknesses in these arguments highlights the questions they raise for economic orthodoxy and points to some interesting parallels between these arguments and those used by the biophysical school of ecological economics while the evidence in favour of jevons paradox is far from conclusive it does suggest that economy wide rebound effects are larger than is conventionally assumed and that energy plays a more important role in driving productivity improvements and economic growth than is conventionally assumed

on countervailing incentives abstract this paper extends and unifies previous work on optimal contracts under countervailing incentives shedding light in particular on the relation between countervailing incentives and pooling inflexible rules our main result is that the nature of the optimal contract depends crucially on whether the agent s utility is quasiconcave or quasiconvex in the private parameter the optimal contract is separated in the former case and it may entail pooling in the latter case journal of economic literature classification number d82

the directional volatility connectedness between crude oil and equity markets new evidence from implied volatility indexes in this paper we use a set of newly introduced implied volatility indexes to investigate the directional connectedness between oil and equities in eleven major stock exchanges around the globe from 2008 to 2015 the inference on the oil equity implied volatility relationships depends on diebold and yilmaz 2012 2014 2015 who proposed a set of directional measures that enable the dynamic and directional characterization of the relationships among financial variables we find uniform results across the sample countries indicating that the connectedness between oil and equity is established by the bi directional information spillovers between the two markets however we find that the bulk of association is largely dominated by the transmissions from the oil market to equity markets and not the other way around the pattern of transmissions is varying over the sample period however most of the linkages between oil and equities are established from the mid of 2009 to the mid of 2012 which is a period that witnessed the start of global recovery

oil price volatility and stock returns in the g7 economies this study examines the relationship between oil price volatility and stock returns in the g7 economies canada france germany italy japan the uk and the us using monthly data for the period 1970 to 2014 in order to measure oil volatility we consider alternative specifications for oil prices world nominal and real prices we estimate a vector autoregressive model with the following variables interest rates economic activity stock returns and oil price volatility taking into account the structural break in the year 1986 we find a negative response of g7 stock markets to an increase in oil price volatility results also indicate that world oil price volatility is generally more significant for stock markets than the national oil price volatility

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

parametric estimation of technical and allocative inefficiency with panel data the error components approach to estimating allocative inefficiency imposes restrictive assumptions on the distributions of the errors and functional form the parametric approach does not require special assumptions about the error distribution or technology but typically assumes technical efficiency or restrictive functional forms the parametric approach also allows for systematic firm responses to shadow prices the authors generalize the parametric approach to a panel data setting and show that input and firm specific allocative inefficiency as well as firm specific technical inefficiency can be identified and estimated using a flexible functional form this is demonstrated empirically with an application to u s airlines copyright 1994 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

on the equivalence of two normalizations in estimating shadow cost functions abstract we show that the shadow cost system that normalizes one price divergence parameter to unity is equivalent to the balk system that equates input costs based on actual and shadow prices which is a simultaneous equation not a seemingly unrelated regression sur system

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

energy performance certificates and investments in building energy efficiency a theoretical analysis abstract in the european union energy performance certificates epcs provide potential buyers or tenants with information on a property s energy performance by mitigating informational asymmetries on real estate markets the conventional wisdom is that they will reduce energy use increase energy efficiency investments and improve social welfare we develop a model that partly contradicts these predictions although epcs always improve social welfare in the absence of market failures other than asymmetric information their impact on energy use and investments is ambiguous and depends both on the time horizon considered and the distribution of energy needs in the population this implies that in a second best world where energy externalities are under priced epcs can damage social welfare

u s stock returns and oil prices the tale from daily data and the 2008 2009 financial crisis abstract using daily data from january 1999 to december 2011 we examine u s stock returns s p 500 dow jones nasdaq and russell 2000 based on a wide range of information including equity vix volatility inflation expectations interest rates gold prices and the usd euro exchange rate the focus is on oil price returns which have been previously found to exert mostly negative effects on u s stock returns identifying the crisis of 2008 2009 as a significant period of economic contraction and subsequent recovery we check the stability of the stock oil relationship by garch and mgarch dcc models prior to the financial crisis stock returns are slightly negatively affected by oil prices and by the usd euro for the subsample of mid 2009 onwards however stock returns are positively affected by oil prices and a weaker usd euro as with inflation expectations we interpret these findings as u s stocks responding positively to expectations of recovery worldwide our proposed explanation is due to the changing correlation between stock markets and oil either by standard garch models or by mgarch dcc models allowing the implied correlation to vary over time

oil price uncertainty and the u s stock market analysis based on a garch in mean var model abstract this paper uses a bivariate garch in mean var model to examine the effect of oil price uncertainty on the u s real stock returns at the aggregate and sectoral levels estimation results suggest that there is no statistically significant effect of oil price volatility on the u s stock returns the absence of an uncertainty effect might be explained by the fact that companies are likely to hedge against fluctuations in oil prices it could also stem from the ability of most companies to transfer the higher cost of oil to customers moreover the impulse responses indicate that accounting for oil price uncertainty oil price increases and decreases have symmetric effects on the u s aggregate stock returns in that energy price increases and decreases are estimated to have equal and opposite effects on the u s financial market however this symmetric effect doesn t hold across all the sectors studied in this paper

the growth of multinational firms in the great recession abstract using a large firm level dataset this paper studies multinational firms performance during the great recession foreign multinationals grew faster than local firms outside of the crisis but slower during the crisis industry and size differences between domestic and foreign owned firms account for much of this slowdown however multinationals from different countries performed differently during the crisis the paper then assesses the role of multinationals in the global recession using a quantitative model had multinationals relative performance remained unchanged during the crisis the median country s aggregate growth would have been 0 12 higher with a range of 0 13 to 0 5 across countries

the decomposition of cost efficiency and the canonical form of cost function and cost share equations abstract this article discusses the decomposition of cost efficiency into parts relating to input or output technical efficiency and input allocative efficiency it derives the canonical forms for the specification of cost function and cost share estimation equations in the presence of technical and allocative inefficiency and in doing so integrates some hitherto unrelated lines of research

jump dynamics with structural breaks for crude oil prices this study investigates the joint phenomena of permanent and transitory components in conditional variance and jump intensity along with verification of structural breaks for crude oil prices we adopt a component arji model with structural break analysis utilizing daily data on west texas intermediate crude oil spot and futures contracts the analytical results verify the existence of permanent and transitory components in conditional variance with the permanent component of conditional variance increasing with the occurrence of a sudden major event such as the iraqi invasion of kuwait operation desert storm and the war between the us and iraq and a relatively greater increase in the transitory component over the same period notably jump intensity fluctuates with an increase in the transitory component of conditional variance in response to abnormal events it is the transitory component which serves as the primary influential factor for jumps in returns therefore speculators are willing to take large risks particularly with respect to anticipating future price movements or gambling in the hopes of rapidly making substantial gains thus speculators prefer the temporary volatility component and engage in trade activities however investors prefer the permanent volatility component because they may well be better off relocating their assets into more stable portfolios to outperform the market portfolio over the long run

interdependencies between transport fuel demand efficiency and quality an application to austria abstract this paper focuses on the interdependencies between technical efficiencies and energy demand which are often either treated in isolation or do not get the sufficient attention in the literature more precisely this paper uses technical efficiencies as one crucial determinant of energy demand in order to integrate at least two issues that are usually investigated separately from each other the rebound effect resulting from improved technical efficiencies and the asymmetry of energy demand in this regard our paper sets out a theoretical framework which has the following implications higher efficiency increases service demand first order rebound low fuel prices and higher efficiency increases the demand for quality second order which in turn increases service demand further third order ceteris paribus energy price shocks should increase scrapping rates fuel prices direct the rd those on engine efficiency are irreversible which has the consequence that energy price elasticities depend on the history of energy prices rather than being asymmetrical derived implications are subsequently tested on austrian data in particular the purchasing decision diesel versus gasoline powered cars allows to refute the myth that consumers apply high implicit rates for discounting the future benefit from efficient cars

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

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

how sensitive are consumer expenditures to retail energy prices abstract there is growing evidence that the primary effect of energy price shocks on the u s economy involves a reduction in consumer spending we quantify the direct effect on real consumption of unanticipated changes in discretionary income shifts in precautionary savings and changes in the operating cost of energy using durables the possibility of asymmetries in the response of real consumption to energy price shocks is also considered we demonstrate that linear models are consistent with the symmetric behavior of real consumption in 1979 when energy prices increased sharply and in 1986 when they fell sharply it is shown that historically energy price shocks have been an important factor in explaining u s real consumption growth but by no means the dominant factor

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

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

white certificates energy efficiency programs under private information of consumers abstract energy efficiency is an objective of public interventions at least since the public utility regulatory policy act of 1978 purpa recently conservation has received considerable attention in the united states and in particular in the european union but this time in order to mitigate global warming policy measures include regulations at the technical level and the introduction of white certificates in order to force utilities and firms to invest into conservation in a way similar to the already existing renewable energy quota this paper derives the optimal mechanism if utilities must deal with white certificates facing consumers holding private information the optimal mechanism has some theoretically interesting features like restricted participation and a discontinuity

the fed and interest rates a high frequency identification we measure monetary policy shocks as changes in the fed funds target rate that surprise bond markets in daily data these shock series avoid the omitted variable time varying parameter and orthogonalization problem of monthly vars and do not impose the expectations hypothesis we find surprisingly large and persistent responses of bond yields to these shocks 10 year rates rise as much as 8 10 of a percent to a one percent target shock the usual view that monetary policy only temporarily raises long term rates and influences inflation would lead one to predict a negative long rate response this abstract was borrowed from another version of this item

the exchange rate exposure of u s multinationals this article examines the exposure of u s multinationals to foreign currency risk evidence is presented that the relationship between stock returns and exchange rates differs systematically across multinationals given these results the study focuses on the determinants of exchange rate exposure the comovements between stock returns and the value of the dollar is found to be positively related to the percentage of foreign operations of u s multinationals copyright 1990 by the university of chicago

the economic effects of energy price shocks large fluctuations in energy prices have been a distinguishing characteristic of the u s economy since the 1970s turmoil in the middle east rising energy prices in the u s and evidence of global warming recently have reignited interest in the link between energy prices and economic performance this paper addresses a number of the key issues in this debate what are energy price shocks and where do they come from how responsive is energy demand to changes in energy prices how do consumers expenditure patterns evolve in response to energy price shocks how do energy price shocks affect u s real output inflation and stock prices why do energy price increases seem to cause recessions but energy price decreases do not seem to cause expansions why has there been a surge in the price of oil in recent years why has this new energy price shock not caused a recession so far have the effects of energy price shocks waned since the 1980s and if so why as the paper demonstrates it is critical to account for the endogeneity of energy prices and to differentiate between the effects of demand and supply shocks in energy markets when answering these questions

international oil price uncertainty and corporate investment evidence from china s emerging and transition economy we develop and estimate a dynamic model of investment to investigate the impact of international oil price uncertainty on corporate investment expenditures in china s emerging and transition economy we further examine whether state ownership affects the relationship between oil price uncertainty and corporate investment consistent with the model s prediction the main finding is that oil price uncertainty exerts a negative impact on corporate investment expenditures in addition compared with state owned listed companies the negative influence of oil price uncertainty on corporate investment is more significant for non state owned listed companies our further analysis using the market oriented reform of refined oil pricing in 2008 as a quasi natural event shows the variation between the low degree marketization period and the high degree one in terms of the relationship between international oil price uncertainty state ownership and corporate investment expenditures

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

the high frequency asymmetric response of stock returns to monetary policy for high oil price events abstract this paper investigates whether a high oil price event that worsens the quality of a firm s balance sheet in turn provides an additional transmission channel to the stock market which then affects stock returns we examine the asymmetric impacts of monetary shocks on stock returns across high oil price events and non high oil price events over the period from 1995 to 2008 we ask how these impacts respond to the relative ability of firms to obtain external finance our findings suggest that more energy intensive industries and durable goods industries react more significantly to monetary shocks based on high oil price events than on those based on non high oil price events by controlling for the capacity for external finance the intraday windows reveal that a monetary surprise for the high oil price events has a bigger impact on stock returns than for the non high oil price events firms with financing constraints find that the adverse impact of a surprise monetary policy action on high oil price events is amplified in the medium profitability category while the impact of a surprise monetary policy action on non high oil price events is amplified in the lowest profitability category

the effect of the normalisation of the shadow price vector on the cost function estimation abstract the shadow cost model can be estimated by adopting two different normalizations of the input price distortions however the normalization suggested by balk econ lett 55 1997 45 produces estimates not invariant to the choice of the shadow input price chosen as numeraire in order to obtain linear homogeneity of the cost function

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

crude oil price uncertainty and corporate investment new global evidence abstract using a comprehensive dataset of more than 33 000 firms from 54 countries in the period 1984 2015 we show that crude oil price uncertainty negatively influences corporate investment more importantly the effect is dependent on the market and stock characteristics of the firms in addition we discover that the effect is stronger in the crude oil producers group than for crude consumers our analysis reveals that the global financial crisis and market volatility phases significantly affect this relationship our results survive a range of robustness tests

uncertainty loss aversion and markets for energy efficiency increasing energy efficiency is critical to mitigating greenhouse gas emissions from fossil fuel combustion reducing oil dependence and achieving a sustainable global energy system the tendency of markets to neglect apparently cost effective energy efficiency options has been called the efficiency gap or energy paradox the market for energy efficiency in new energy using durable goods however appears to have a bias that leads to undervaluation of future energy savings relative to their expected value this paper argues that the bias is chiefly produced by the combination of substantial uncertainty about the net value of future fuel savings and the loss aversion of typical consumers this framework relies on the theory of context dependent preferences the uncertainty loss aversion bias against energy efficiency is quantifiable making it potentially correctible by policy measures the welfare economics of such policies remains unresolved data on the costs of increased fuel economy of new passenger cars taken from a national research council study illustrate how an apparently cost effective increase in energy efficiency would be uninteresting to loss averse consumers

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

the linkages between oil market uncertainty and islamic stock markets evidence from quantile on quantile approach abstract in recent years islamic finance has become increasingly influential especially islamic stocks which have created huge investment attractiveness at the same time the financialization of oil has made the international oil market increasingly uncertain and more likely to affect other markets to effectively understand the correlation between the two markets we empirically analyze the cases of four typical countries from the perspective of oil market uncertainty this paper utilizes ovx as an accurate measure of oil market uncertainty and applies quantile on quantile approach to detect the asymmetric and heterogeneous relations between the variables our results show overall negative linkages between ovx changes and islamic stock returns and there is indeed asymmetry namely the effects of oil market uncertainty will be more pronounced when it is at higher quantiles further comparing the results of the selected four countries we find some heterogeneities oil importing countries are more sensitive than oil exporting countries and islamic countries are more sensitive than non islamic countries the findings of this article about the linkages between oil market uncertainty and islamic stock markets is meaningful to the research and financial practice in related fields

incentives for conservation and quality improvement by public utilities the author examines the design of incentive programs to motivate regulated utilities to supply both basic service e g electricity supply local telephone service and service enhancements e g energy conservation services improved clarity and speed of voice communication the optimal regulatory programs are shown to vary greatly depending upon the information available to the regulator the price of the basic service may optimally be distorted above or below marginal cost to better motivate the supply of the service enhancement policy prescriptions are compared with current programs and proposals to promote energy conservation 35 refs 2 figs

firm size and the demand for energy in dutch manufacturing 1978 1986 as in most other industrialized countries the oil price shocks in the seventies led to major rearrangements in the production processes in dutch manufacturing the substitution of expensive energy consuming processes by less energy intensive ones is analyzed by means of a dynamic equation relating the energy demand to the level of output the price of energy and the prices of other inputs using a rather unique data set consisting of panel data pertaining to several thousands of manufacturing firms it is found that large firms can reduce energy costs more than small firms

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

oil volatility shocks and the stock markets of oil importing mena economies a tale from the financial crisis abstract the role of oil price volatility in predicting the stock market volatility of small oil importing countries that have a substantial number of investors from neighboring oil exporting countries remains unexplored to refine our basic understanding of this role this paper proposes a methodological extension of the recently developed causality in variance procedure and considers the case of lebanon and jordan these two heavy importers of oil are interesting in the sense that they are located in a region with a large number of rich oil exporting countries so their stock markets are tied to oil exporters by way of foreign investors the conditional mean and variance of returns are modeled within an armax garch framework that accommodates three salient features of the data namely autocorrelation day of the week effects and movements in international markets for comparison purposes the stock markets of morocco and tunisia are also included in the study empirical analyses highlight the dynamic effects of the global financial crisis on the volatility spillovers between oil and the stock markets of oil importing countries and provide more insights into the seemingly contradictory effects of being oil importers while having investors from oil exporting countries the main results indicate that the volatility spillover is much more apparent from the world oil market to the stock market of jordan than the other way around whereas oil volatility is not a good predictor of lebanese stock market volatility finally policy practical implications and conclusions for future research are drawn
