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

energy disruptions interfirm price effects and the aggregate economy in an economy with many imperfect competitors monopolistic competition firms that pass through higher oil prices during a disruption will affect the demand for firms in other industries firms that charge higher prices for their final product will include the effect on their own final product in their private decisions but will exclude the effect on the final products of other firms although a pecuniary externality these actions will reduce society s welfare unlike the case of a perfectly competitive market this situation creates a societal risk that is much wider than an externality in any single market policy interest shifts from one of punishing persian gulf oil producers to one of cushioning an industrialized economy from sudden disruptions caused by political and military conflicts although the value of reducing oil use depends upon a number of unknown parameters with wide distributions a representative numerical example suggests that it may approach 5 per barrel

the role of the trade channel in the propagation of oil supply shocks abstract this paper analyzes when and why idiosyncratic oil supply shocks produce large macroeconomic effects in an analytically tractable two country general equilibrium model we focus on a demand driven mechanism the trade channel which transmits oil shocks across economies through changes in the non oil goods terms of trade when the trade channel is operative we have three main consequences on the transmission of oil shocks first the macroeconomic impact of oil shocks may be large and asymmetric across countries second the magnitude of the effects is nonlinear in the size of the oil shock third terms of trade movements never ensure international risk sharing after an idiosyncratic oil supply shock

the role of capital and labour in shaping the environmental effects of fiscal stimulus abstract although the macroeconomic consequences of short term fiscal stimulation packages have been thoroughly analysed in the literature still relatively little is known about their environmental effects we discuss an important channel through which short run expansionary fiscal policy influences greenhouse gas emissions we show that fiscal policy exerts its impact not only by increasing general level of economic activity but also by changing the composition of factors of production capital and labour using the dynamic stochastic general equilibrium model of economy we demonstrate that fiscal expansion results in a shift from capital intensive to more labour intensive technologies our panel study proves that the latter tends to be associated with lower emissions of greenhouse gases per unit of production hence our analysis demonstrates that an extensive use of fiscal stimulus during recessions can significantly reduce the environmental burden of the additional units of gdp

energy price shocks and medium term business cycles abstract energy price shocks pose sudden challenges to economies this paper examines how oil price shocks have influenced the u s economy over the last decades and especially focuses on the productivity slowdown in the years following an oil price shock we extend the existing literature by considering medium term business cycles which consist of high frequency components conventional business cycles up to 8 years and medium frequency components 8 50 years we find that the medium frequency consequences of energy price shocks are considerable and explain a significant part of the productivity slowdown

implicit contracts and the cyclicality of the skill premium to examine the cyclical behavior of the skill premium this paper introduces implicit labor contracts in a dsge model where production is characterized by capital skill complementarity and the utilization of capital is endogenous it is shown that this model can reproduce the observed cyclical patterns of wages and the skill premium the feature of capital skill complementarity coupled with variable capital utilization rates does not come at odds with the acyclical behavior of the skill premium the paper argues that the skill complementarity of capital is not a quantitatively significant factor at high frequencies the key aspects are the contracts and the capital utilization margin

on the price of recreation goods as a determinant of male labor supply we examine whether and how variations in the price of recreation goods influence men s allocation of market work for the united states individual level data are combined with metropolitan area level price indices to estimate the male elasticity of intertemporal substitution of market work with respect to the price of recreation goods which is found around 0 16 and statistically significant the allocation of market work in response to changes in the price of recreation goods would create movements in the output of an economy moreover it could contribute toward explaining the emerging differences in work and leisure between the united states and europe

a multidimensional approach to the influence of environmental marketing and orientation on the firm s organizational performance since it implies a reduction in the quality and the quantity of the natural resources environmental degradation is a present day problem that requires immediate solutions this situation is driving firms to undertake an environmental transformation process with the purpose of reducing the negative externalities that come from their economic activities within this context environmental marketing is an emerging business philosophy by which organizations can address sustainability issues moreover environmental marketing and orientation are seen as valuable strategies to improve a firm s competitiveness however the literature that has analyzed the link between environmental strategies and firms results has been inconclusive and contradictory in this study we propose and test a model that analyses how the implementation of ecological issues within a firm s marketing strategy and orientation influences organizational results data were obtained through a survey sent to spanish manufacturing firms the results show that environmental marketing positively affects firms operational and commercial performance and this improvement will influence their economic results moreover environmental marketing is revealed as an excellent strategy to obtain competitive advantages in costs and in product differentiation thus this study agrees with the researchers who affirm that environmental strategies positively affect firm s competitiveness while reducing environmental impact

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

lessons from photovoltaic policies in china for future development abstract the paper first provides an overview of the current status of pv industry development in china including the penetration speed the market segments and the value chain further it reviews the experience of governmental interventions composed of the legal framework market incentives and manufacturing policies for lessons learning after the renewable energy law took effect in 2006 pv penetration was accelerated capital subsidies and feed in tariffs which were still in a trial stage public bidding and the cooperation among relevant ministries played important roles a series of public rd the budget and the organization of public pv r d were insufficient finally we propose some recommendations on improving policy interventions

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

regime switching in the reactions of stock markets in saudi arabia to oil price variations the study revisits the stock oil nexus by examining the reactions of equity markets to oil price shocks at national and sectoral levels for saudi arabia in a time varying framework by employing the markov switching egarch model developed by henry 2009 journal of banking and finance 33 405 based on weekly data the findings reveal that the behaviour of all stock markets switches between an expansion regime and a recession regime with more persistence for the expansion state additionally influential international events associated with stock market drops are clearly identified in the recession regime furthermore there is evidence of asymmetric reactions of the equity index returns and the probabilities of transition from one state to another to oil price variations with heterogeneous impacts across sectors and regimes the stock markets are more sensitive to oil price decreases than to oil price increases although the evidence of relatively slight differences in some findings across weekdays the study allows investors and policymakers to understand well the interactions of stock sector markets vis a vis the world oil market in a regime switching framework in order to make the right decision as regards portfolio diversification and regulation of the stock markets

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

implicit contracts life cycle labor supply and intertemporal substitution the implicit contract model is a serious alternative to the spot market interpretation of the labor market however its usefulness has been limited because the wage is unobserved and hence it has not been possible to estimate an intertemporal frisch supply elasticity for the model using microdata in this article we show that one can estimate this elasticity from microdata within the context of the implicit contract model under relatively weak assumptions based on consumer theory we implement our approach on two micro data sets and for both obtain a reasonably precise elasticity estimate of approximately 1 0

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

volatility spillovers between oil prices and stock sector returns implications for portfolio management abstract in this article we take a recent generalized var garch approach to examine the extent of volatility transmission between oil and stock markets in europe and the united states at the sector level the empirical model is advantageous in that it typically allows simultaneous shock transmission in the conditional returns and volatilities insofar as volatility transmission across oil and stock sector markets is a crucial element for portfolio designs and risk management we also analyze the optimal weights and hedge ratios for oil stock portfolio holdings with respect to the results our findings point to the existence of significant volatility spillover between oil and sector stock returns however the spillover is usually unidirectional from oil markets to stock markets in europe but bidirectional in the united states our back testing procedures finally suggest that taking the cross market volatility spillovers estimated from the var garch models often leads to diversification benefits and hedging effectiveness better than those of commonly used multivariate volatility models such as the ccc garch of bollerslev 1990 the diagonal bekk garch of engle and kroner 1995 and the dcc garch of engle 2002

does high frequency crude oil futures data contain useful information for predicting volatility in the us stock market new evidence abstract this study examines whether high frequency crude oil futures data contain useful information to forecast the realized volatility rv of the us stock market from both in and out of sample perspectives there are several significant findings first from the in sample analysis crude oil futures rv exhibits a significant positive impact on the future s p 500 volatility second the out of sample results reveal that the prediction models including crude oil futures rv outperform the related competing models implying that crude oil rv is an important predictive factor for the us stock market third we further find that the primary forecasting ability of crude oil rv is reflected in high frequency information negative crude oil rv and high volatility level finally the out of sample empirical results based on different forecasting windows alternative forecast evaluation approaches subsample analysis different prediction models alternative midas lags and controlling the leverage effect are robust to our conclusions

an empirical model of labor supply in a life cycle setting this paper formulates and estimates a structural intertemporal model of labor supply using theoretical characterizations derived from an economic model of lifetime behavior a two step empirical analysis yields estimates of intertemporal and uncompensated substitution effects which provide the information needed to predict the response of hours of work to life cycle wage growth and shifts in the lifetime wage path

how green management influences product innovation in china the role of institutional benefits does being green facilitate product innovation this study examines whether green management in firms operating in china fosters radical product innovation to a greater extent than it does incremental product innovation and investigates the underlying institutional mechanisms involved in the relationship between green management and product innovation the findings show that green management is more likely to lead to radical product innovation than to incremental product innovation moreover government support as a formal institutional benefit more strongly mediates the effect of green management on radical product innovation than its effect on incremental product innovation whereas social legitimacy as an informal institutional benefit more strongly mediates the effect of green management on incremental product innovation than its effect on radical product innovation these findings provide important implications for explaining how firms employ green management to facilitate product innovation 2014 springer science business media dordrecht

analysing systemic risk and time frequency quantile dependence between crude oil prices and brics equity markets indices a new look abstract this paper examines the dependence structure and the systemic risk between the return series of oil prices and the brics equity market indices using the newly developed methods of the quantile coherency of barunik and kley 2015 and the nonparametric conditional value at risk causality ncovar and the ncovar granger causality tests ncovar gc of diks and wolski 2018 for the period 2001 2018 further the traditional tests of hiemstra and jones 1994 and diks panchenko 2005 are used for comparison purposes the new methods have given rise to findings that are substantially different from those based on the two traditional approaches from our frequency dependence analysis we find a significant long term dependence coherency between the russian brazilian and south african stock markets and oil shifts however the ncovar analysis demonstrates a robust instantaneous dependence in both directions between almost all of the brics stock markets the exception is the indian market and the oil market the ncovar gc analysis reveals a robust lagged dependence from the oil market onto the chinese stock market only these findings provide helpful insights for regulators and potential international investors

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

oil shocks and financial systemic stress international evidence abstract by conducting a structural var analysis on the financial systemic stress in 20 countries this paper provides international evidence that oil structural shocks impact not only stress in individual financial markets but also their connectedness the oil structural shocks explain a large fraction of the variation in the connectedness among various financial markets the effect of oil structural shocks on financial systemic stress is largely dependent on the origins of oil price changes and a country s net oil export position in most oil importing economies financial systemic stress is negatively impacted by supply and aggregate demand shocks and positively impacted by oil market specific demand shocks opposite patterns are detected in oil exporting economies the effects of the spillovers are asymmetrically related with market conditions during normal periods more risks are spilled over from the oil market to financial systems but during financial crises the opposite occurs in periods of financial crises and oil price collapses there is noticeable contagion between the oil market and financial systems

mainstreaming green product innovation why and how companies integrate environmental sustainability green product innovation has been recognized as one of the key factors to achieve growth environmental sustainability and a better quality of life understanding green product innovation as a result of interaction between innovation and sustainability has become a strategic priority for theory and practice this article investigates green product innovation by means of a multiple case study analysis of 12 small to medium size manufacturing companies based in italy and canada first we propose a conceptual framework that presents three key environmental dimensions of green product innovation such as energy minimization materials reduction and pollution prevention as identified in the life cycle phases of products based on insights gained from in depth interviews we discuss firms motivations to develop green products environmental policies and targets for products different dimensions of green product innovation and challenges faced during developing and marketing of green products results from the study are then synthesized and integrated in a toolbox that sheds light on various aspects of green product innovation and provides solutions to challenges and risks that are faced by firms finally implications for managers academia and public policy makers are discussed

the effects of energy price technology and disaster shocks on china s energy environment economy system abstract this paper constructs a dynamic stochastic general equilibrium dsge model to analyze the effects of energy price technology and disaster shocks on china s energy environment economy 3e system it also studies stylized facts as well as co integration and error correction dynamic analyses of this system the disaster shock is modeled as a two state markov switching process the results show that both technology and energy price shocks increase the ratio of environmental investment to gdp the improvement in technology and rising energy prices helps to reduce co2 pollution and improve economic restructuring among the three kinds of shocks technology shock is the most important the robustness of the model is tested through statistical methods

testing between competing models of real business cycles this paper tests a real business cycle model with efficient long term labor contracts the efficient long term contract model against a standard real business cycle model the intertemporal substitution model in the former model employment and real wages are determined by bilateral dynamic bargaining between firms and workers in the latter model employment and real wages are determined instead by the dynamic optimization of households within the competitive market framework we estimate each model using aggregate japanese data our results show that the data are consistent with the efficient long term contract model but are inconsistent with the intertemporal substitution model a business cycle phenomenon is typically found in time series data on employment and real wages according to the data of almost all developed countries employment fluctuations are considerably greater than wage fluctuations many recent economic studies have attempted to explain this phenomenon most of these studies fall into the equilibrium business cycle theory in which business cycles are the result of individual agents optimizing in a competitive environment among the most famous early examples of such a theory are the rational expectations general equilibrium models of lucas 1972 and barro 1976 which stress the role of nominal shocks in the presence of imperfect information more recently the predominant equilibrium business cycle theory has been the real business cycle model of kydland and prescott 1982 long and plosser 1983 and king and plosser 1984 which emphasizes the importance of real shocks to production technology real business cycle theory considers a model economy populated by a single infinitely lived individual with given initial resources production possibilities and tastes the representative individual chooses a preferred consumption production plan and the resulting allocation is pareto optimal the implications of real business cycle theory are thus derived from the pareto optimal equilibrium allocation as calculated from the planning problem of a social planner or representative agent a policy implication of this theory is that monetary policy has no significant effect

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

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

tightening environmental standards the benefit cost or the no cost paradigm ms ff ichael porter and claas van der linde have written a paper that is interesting and to us at least somewhat astonishing it is a defense of environmental regulation indeed an invitation to more stringent regulation that makes essentially no reference to the social benefits of such regulation this approach contrasts starkly with the methods that economists and other policy analysts have traditionally used when assessing environmental or other regulatory programs the traditional approach consists of comparing the beneficial effects of regulation with the costs that must be borne to secure these benefits for environmental regulation the social benefits include the reductions in morbidity or premature mortality that can accompany cleaner air the enhanced recreational opportunities that can result from water quality improvements the increased land values that might attend the cleanup of a hazardous waste site the enhanced vitality of aquatic ecosystems that might follow reductions in agricultural pesticide use or any of the other potentially significant benefits associated with tighter standards from this benefit cost approach emerges the standard tradeoff discussed in virtually every economics textbook porter and van der linde deny the validity of this approach to the analysis of environmental regulation claiming it to be an artifact of what they see as a static mindset in their view economists have failed to appreciate the capacity of

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

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

energy and economic growth in the usa a multivariate approach abstract this paper examines the causal relationship between gdp and energy use for the period 1947 90 in the usa the relationship between energy use and economic growth has been examined by both biophysical and neoclassical economists in particular several studies have tested for the presence of a causal relationship in the granger sense between energy use and economic growth however these tests do not allow a direct test of the relative explanatory powers of the neoclassical and biophysical models a multivariate adaptation of the test vector autoregression var does allow such a test a var of gdp energy use capital stock and employment is estimated and granger tests for causal relationships between the variables are carried out although there is no evidence that gross energy use granger causes gdp a measure of final energy use adjusted for changing fuel composition does granger cause gdp

does the source of oil price shocks matter for south african stock returns a structural var approach abstract in this paper we investigate the dynamic relationship between different oil price shocks and the south african stock market using a sign restriction structural var approach for the period 1973 01 to 2011 07 the results show that for an oil importing country like south africa stock returns only increase with oil prices when global economic activity improves in response to oil supply shocks and speculative demand shocks stock returns and the real price of oil move in opposite directions the analysis of the variance decomposition shows that the oil supply shock contributes more to the variability in real stock prices the main conclusion is that different oil price shocks affect stock returns differently and policy makers and investors should always consider the source of the shock before implementing a policy and making investment decisions

asymmetric volatility spillovers between uk regional worker flows and vacancies this paper investigates volatility spillovers between uk regional job finding job separation and vacancy rates employing a large bayesian logistic smooth transition vector autoregression var model we find high volatility spillovers between uk regional labour markets analyses of net spillovers show that in general shocks to job separation rates tend to spread into job finding and vacancy rates while vacancy rates are usually at the receiving end of shocks transmitted from the job separations and job findings to shed further light on the shock propagation mechanism we also look into more detailed matters such as the differences in spillovers between regions within the same regime and that of the same region but in different regimes

the heterogeneity dependence between crude oil price changes and industry stock market returns in china evidence from a quantile regression approach this paper explores the dependence between real crude oil price changes and chinese real industry stock market returns based on the monthly data from 1994 03 to 2014 06 we address this issue using the quantile regression approach enabling a more detailed investigation of structure and degree of dependence empirical results reveal that the reaction of market returns to crude oil is highly heterogeneous across conditional distribution of industry stock returns furthermore there is evidence that this dependence is positive and exists only in recessions or bearish markets with low expected returns the dependence at low quantiles is not limited to one market but is a common feature across industries additionally dependence also changes since the onset of structural breaks we determine that chinese industry stock and global crude oil markets have contagion in rare situations most cases do not demonstrate contagion

international business cycles world region and country specific factors the paper investigates the common dynamic properties of business cycle fluctuations across countries regions and the world we employ a bayesian dynamic latent factor model to estimate common components in macroeconomic aggregates output consumption and investment in a 60 country sample covering seven regions of the world the results indicate that a common world factor is an important source of volatility for aggregates in most countries providing evidence for a world business cycle we find that region specific factors play only a minor role in explaining fluctuations in economic activity we also document similarities and differences across regions countries and aggregates jel f41 e32 c11 c32

commodity price volatility with endogenous natural resources abstract natural resource reserves are exogenous in models of small commodity exporters changes in the stock of reserves play no role in the macroeconomy including in business cycle volatility trade dynamics or exchange rate volatility we consider richer supply dynamics and model exploration and depletion we show that an endogenous supply of reserves is important for capturing the stylised facts associated with commodity price shocks including a commodity currency the crowding out of non commodity activity dutch disease and a volatile business cycle we also consider how exploration and depletion affect the ranking of optimal monetary and taxation policies when natural resource reserves are held fixed monetary policy is an efficient tool for stabilising the effects of commodity price shocks however when exploration and depletion are accounted for using interest rates to stabilise the effects of commodity price changes becomes inefficient using taxes on the resource sector specifically an ad valorem royalty remains efficient

the effects of oil price shocks on output and inflation in china crude oil price shocks derive from many sources each of which may bring about different effects on macro economy variables and require completely different designs in macro economic policy thus distinguishing the sources of oil price fluctuations is crucial when evaluating these effects this paper establishes an open economy dynamic stochastic general equilibrium dsge model with two economies china and the rest of the world to assess the effects of oil price shocks the ces production function is extended by adding oil as an input based on the model the effects of four types of oil price fluctuations are evaluated the four types of oil price shocks are supply shocks driven by political events in opec countries other oil supply shocks aggregate shocks to the demand for industrial commodities and demand shocks that are specific to the crude oil market simulation results indicate the following oil supply shocks driven by political events mainly produce short term effects on china s output and inflation while the other three shocks produce relatively long term effects in addition demand shocks that are specific to the crude oil market contribute the most to the fluctuations in china s output and inflation

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

intertemporal substitution exogeneity and surprises estimating life cycle models for canada the authors estimate consumption and labor supply models for canada using u s variables as instruments instead of lagged canadian variables the results suggest that the endogeneity of lagged variables has not been a serious problem in previous studies they also develop estimation methods for use when the agents information sets are unknown and the model contains the realization and the innovation of an endogenous variable the authors use the approach to estimate a labor supply model combining intertemporal substitution and job search and to estimate the labor supply and consumption responses to marginal utility of income changes induced by wage price and interest rate surprises

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

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

oil shocks and production network structure evidence from the oecd abstract does the production network structure matter for the transmission of oil shocks using a bayesian time varying var the paper derives the impact of oil shocks on gdp for a set of oecd economies it further estimates various measures to characterize the production network structure based on input output matrices when the relationship between the time varying responses of gdp to oil demand and oil supply shocks and production network characteristics is analyzed the paper finds that measures like skewness in the in degrees and in the out degrees or density tend to amplify the negative impact of oil shocks on gdp the results here are in line with the recent literature that outlines the importance of network structures for aggregate dynamics

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

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

oil price shocks and china s economy reactions of the monetary policy to oil price shocks abstract the paper empirically analyzes the effect of positive oil price shocks on china s economy having special interest in the response of the chinese interest rate to those shocks using different econometric models i a time varying parameter structural vector autoregression tvp svar model with short run identifying restrictions ii a structural var svar model with the short run identifying restrictions and iii a var model with ordering free generalized impulse response var gir var we find that the response of the chinese interest rate to the oil price shocks is not only time varying but also showing quite different signs of responses specifically in the earlier sample period 1992 4 2001 10 the interest rate shows a negative response to the oil price shock while in the latter period 2001 11 2014 5 it shows a positive response to the shock given the negative response of the world oil production to an oil price shock in the earlier period the shock is identified as a negative supply shock or a precautionary demand shock as suggested by kilian 2009 thereby the negative response of the interest rate to the oil price shock is deemed as economy boosting the positive response of the interest rate to the oil price shock in the later period given that this shock is identified as a positive world oil demand shock gives evidence that stabilization of inflation is one of the main objectives of china s monetary authority even though the current main objective of the monetary policy is characterized as maintaining the stability of the value of the currency and thereby promoting economic growth finally the variance decomposition results reveal that the oil price shock becomes an increasingly important source in the volatility of china s interest rate

towards a more general approach to testing the time additivity hypothesis a new procedure is proposed for re examining the assumption of additivity of preferences over time which although untenable is usually maintained in intertemporal analyses of consumption and labour supply the method is an extension of a famous work by browning however it is more general in permitting the estimation of intertemporal demand systems which are explicit in an unobservable variable price of utility but may lack a closed form representation in terms of observable variables such as prices and total outlay it also makes extensive use of duality theory to solve the endogeneity problem encountered in browning s study applying this method with an appropriate estimator to the australian aggregate data it is found that the time additivity hypothesis is decisively rejected which is consistent with browning s conclusion

the impact of environmental management on firm performance environmental management has the potential to play a pivotal role in the financial performance of the firm many individuals suggest that profitability is hurt by the higher production costs of environmental management initiatives while others cite anecdotal evidence of increased profitability a theoretical model is proposed that links strong environmental management to improved perceived future financial performance as measured by stock market performance the linkage to firm performance is tested empirically using financial event methodology and archival data of firm level environmental and financial performance significant positive returns were measured for strong environmental management as indicated by environmental performance awards and significant negative returns were measured for weak environmental management as indicated by environmental crises the implicit financial market valuation of these events also was estimated cross sectional analysis of the environmental award events revealed differences for first time awards and between industries first time award announcements were associated with greater increases in market valuation although smaller increases were observed for firms in environmentally dirty industries possibly indicative of market skepticism this linkage between environmental management and financial performance can be used by both researchers and practitioners as one measure of the benefits experienced by industry leaders and as one criterion against which to measure investment alternatives

testing intertemporal substitution implicit contracts and hours restriction models of the labor market using micro data we present new tests of three theories of the labor market intertemporal substitution hours restrictions and implicit contracts the intertemporal substitution test we implement is an exclusion test robust to many specification errors and we consistently reject this model we model hours restrictions as part of an endogenous switching model we compare the implicit probit equation to an unrestricted probit equation for unemployment and reject the hours restriction model for the implicit contracts model we estimate non separable within period labor supply and consumption equations we test a cross equation restriction of the model and cannot reject the implicit contracts model jel e30 j22 j60

self fulfilling expectations and the inflation of the 1970s evidence from the livingston survey abstract using survey data on expectations we examine whether the response of monetary policy to sudden movements in expected inflation contributed to the persistent high inflation of the 1970s the evidence suggests that prior to 1979 the fed accommodated temporary shocks to expected inflation which then led to persistent increases in actual inflation we do not find this behavior in the post 1979 data among commonly cited factors oil and fiscal shocks do not appear to have triggered an increase in expected inflation that eventually resulted in higher actual inflation

asset prices and expected monetary policy evidence from daily data this article explores the relationships among libor gold prices the exchange rate oil prices fed funds futures prices and stock prices at a daily frequency this article examines whether expected monetary policy measured by changes in the prices of fed funds futures contracts reacts to high frequency changes in asset prices and in turn whether asset prices respond to changes in expected monetary policy the article reveals that there are statistically significant relationships between expected us monetary policy and shocks to libor and exchange rates it also reveals that there is no evidence of a systematic relationship between stock prices and expected monetary policy changes splitting the data into expansionary and recessionary periods using nber dating we find results for the expansionary periods that are very similar to the results for the entire period for the periods of recession we find little evidence of significant linkages between markets

exogenous oil supply shocks how big are they and how much do they matter for the u s economy abstract the paper proposes a new measure of exogenous oil supply shocks the timing the magnitude and the sign of this measure may differ greatly from current state of the art estimates it is shown that only a small fraction of the observed oil price increases during oil crisis periods can be attributed to exogenous oil production disruptions exogenous oil supply shocks cause a sharp drop of u s real gdp growth after five quarters rather than an immediate and sustained reduction in economic growth and a spike in cpi inflation after three quarters overall exogenous oil supply shocks made remarkably little difference for the evolution of the u s economy since the 1970s although they did matter for some historical episodes

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

oil prices and economic downturns the case of spain abstractwe address the macroeconomic effects of an oil price shock in spain we apply a vector autoregression model var analysis to quarterly data for the spanish economy since 1986 to elucidate the effects of variations in the oil price on the economy considering the three main causes of disruptions in the oil markets oil supply shocks oil demand shocks and oil specific precautionary demand shocks we conclude that the effects in spain strongly depend on the type of shock the consumer price index cpi has mainly been influenced by oil demand shocks output has only reacted to oil supply shocks and monetary policy has mainly reacted after precautionary shocks second round effects caused by the behaviour of nominal wages have not been found additionally we discuss two facts the ability of firms to increase markups in a context of rising demand and the procyclical role of monetary policy when faced with oil demand shocks

how does environmental corporate social responsibility matter in a dysfunctional institutional environment evidence from china drawing on institutional and signaling theories this study examines how environmental corporate social responsibility ecsr affects firm performance in a dysfunctional institutional environment we extend the ecsr literature by suggesting that ecsr indirectly influences firm performance through the mediating effects of business and political legitimacy based on a dataset of 238 firms in china we find that ecsr affects business and political legitimacy followed by firm performance moreover legal incompleteness weakens and legal inefficiency strengthens the effects of ecsr on business and political legitimacy

on the identification of frisch labor supplies abstract this paper determines which structural components of the intertemporal decision process can be recovered from labor supply estimates obtained using heckman and macurdy s approach

the cyclical behavior of monthly nymex energy prices abstract this paper systematically investigates the basic stylized facts of energy price movements using monthly data for the period that energy has been traded on organized exchanges and the methodology suggested by kydland and prescott kydland f e prescott e c 1990 business cycles real facts and a monetary myth fed reserve bank minneapolis q rev spring 3 18 the results indicate that energy prices are in general procyclical in contrast to the accepted fact that energy prices are countercyclical and leading the cycle

the effect of income taxation on consumption and labor supply we estimate the incentive effects of income taxation in a life cycle model of consumption and labor supply without intratemporal strong separability we find that consumption and hours worked are direct complements in utility both increase with a compensated increase in the net wage the compensated net wage elasticity is about 0 3 nearly double estimates for u s men from a linear labor supply specification estimated intertemporal elasticities indicate significant intertemporal smoothing of utility the estimated marginal welfare cost of government revenue is 6 20 which is about half the estimated welfare cost when additivity between consumption and leisure is incorrectly imposed

commodity prices and fiscal policy design procyclical despite a rule recent studies offer evidence of reduced fiscal procyclicality to commodity price changes in resource rich countries a feature commonly attributed to the adoption of fiscal policy rules we revisit this issue and find that by controlling for global activity shocks while allowing for time varying changes in both fiscal policy and the volatility of shocks this finding does not hold to show this we develop a time varying dynamic factor model allowing for a multiple of shocks stochastic volatility and time varying parameters and estimate it on data for norway whose handling of resource wealth is often cited as exemplary

beyond does it pay to be green a meta analysis of moderators of the cep cfp relationship review of extant research on the corporate environmental performance cep and corporate financial performance cfp link generally demonstrates a positive relationship however some arguments and empirical results have demonstrated otherwise as a result researchers have called for a contingency approach to this research stream which moves beyond the basic question does it pay to be green and instead asks when does it pay to be green in answering this call we provide a meta analytic review of cep cfp literature in which we identify potential moderators to the cep cfp relationship including environmental performance type e g reactive vs proactive performance firm characteristics e g large vs small firms and methodological issues e g self report measures by analyzing these contingencies this study attempts to provide a basis on which to draw conclusions regarding some inconsistencies and debates in the cep cfp research some of the results of the moderator analysis suggest that small firms benefit from environmental performance as much or more than large firms us firms seem to benefit more than international counterparts and environmental performance seems to have the strongest influence on market measures of financial performance

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

a study of management perceptions of the impact of corporate social responsibility on organisational performance in emerging economies the case of dubai although a number of studies have shown that corporate social responsibility csr activities often lead to greater organisational performance in western developed economies researchers are yet to examine the strategic value of csr in emerging economies using survey data from 280 firms operating in dubai this study examines the link between csr activities and organisational performance the results show that csr has a positive relationship with all three measures of organisational performance financial performance employee commitment and corporate reputation these results reinforce the accumulating body of empirical support for the positive impact of csr on performance and challenge the dominant assumption that given the weak institutional framework in emerging economies csr activities drain resources and compromise firms competitiveness

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
