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

international oil shocks and household consumption in china abstract we investigate the impacts that oil price shocks have on residential consumption in china while it is well understood that oil prices affect consumption in a multitude of ways the timing and directness of these effects on specific consumption categories is not clear we demonstrate that the most immediate and direct effect passes through transportation consumption as might be expected but we also show that significant effects pass through consumption in other sectors including food and clothes medical expenditure and other general living expenditure with less immediacy given the results particularly observed asymmetries with respect to rises and falls in international oil prices we discuss some implications for future adjustments to domestic price policies in particular the case for removal of domestic price regulation

does crude oil price play an important role in explaining stock return behavior abstract employing the ms arji gjr garch x model in which the parameters for the jump process the asymmetric garch effect and the impacts of oil price shocks are regime dependent this paper analyzes the impact of crude oil price shock on stock return dynamics empirical results reveal three interesting findings first incorporating the asymmetric garch effect and the oil price shock can substantially improve fitting ability second the garch and jump components show very different behaviors during turbulent and stable periods third the effects of current and past oil price shocks differ the conditional mean mean of jump size and variance of jump size immediately respond to a current oil price shock a one period lagged oil price shock no matter whether positive or negative can affect the transition probability that the stock market will remain conditional in the next period moreover the effects of lagged positive and negative shocks on transition probabilities are very different

the causal relationship between biomass energy use and economic growth in the united states abstract this paper examines the causality relations among economic growth biomass energy consumption employment and capital in the u s between 1961 and 2011 using the ardl bounds testing approach to cointegration long and short run relationships among the variables are estimated long run and short run coefficients indicate that biomass energy consumption has positive impacts on economic growth for the u s in addition the granger causality results illustrate that unidirectional causality from biomass energy consumption to real gdp supportive of the growth hypothesis

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

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

modeling systemic risk and dependence structure between oil and stock markets using a variational mode decomposition based copula method abstract this study combines the variational mode decomposition vmd method and static and time varying symmetric and asymmetric copula functions to examine the dependence structure between crude oil prices and major regional developed stock markets s p500 stoxx600 djpi and tsx indexes during bear normal and bull markets under different investment horizons furthermore it analyzes the upside and downside short and long run risk spillovers between oil and stock markets by quantifying three market risk measures namely the value at risk var conditional var covar and the delta covar covar the results show that there is a tail dependence between oil and all stock markets for the raw return series by considering time horizons we show that there is an average dependence between the considered markets for the short run horizons however the tail dependence is also found for the long run horizons between the oil and stock markets with the exception of the s p500 index which exhibits average dependence with the oil market moreover we find strong evidence of up and down risk asymmetric spillovers from oil to stock markets and vice versa in the short and long run horizons finally the market risk spillovers are asymmetric over the time and investment horizons

china and the relationship between the oil price and the dollar abstract we study cointegration and causality between the real price of oil and the real price of the dollar over the 1974 2004 period our results suggest that a 10 rise in the oil price coincides with a 4 3 appreciation of the dollar in the long run and that the causality runs from oil to the dollar through the development of a theoretical model we then investigate possible reasons why this relationship could be reversed in the future due to the emergence of china as a major player on both the oil and the foreign exchange markets

the transmission of democracy from the village to the nation state we provide evidence that a history of democracy at the local level is associated with contemporary democracy at the national level auxiliary estimates show that a tradition of local democracy is also associated with attitudes that favor democracy with better quality institutions and higher level of economic development

a broadened causality in variance approach to assess the risk dynamics between crude oil prices and the jordanian stock market within the new developed causality in variance approach this paper builds up a broad methodological framework to more accurately capture the risk spillover effects between global oil prices and jordanian stock market returns during the period 1 march 2003 31 january 2014 the sample period is divided on the basis of the 2008 financial crisis into pre crisis and post crisis periods results for the pre crisis period show a lack of risk spillovers between global oil and the jordanian stock market after the crisis however we find evidence for one way risk spillover running from the oil market these findings have implications for the design of appropriate asset allocation and regulatory policies to manage risk spillover effects

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

revisiting the effects of regional trade agreements on trade flows with proper specification of the gravity model this paper uses a gravity model to assess ex post regional trade agreements the model includes 130 countries and is estimated with panel data over the period 1962 1996 the introduction of the correct number of dummy variables allows for identification of vinerian trade creation and trade diversion effects while the estimation method takes into account the unobservable characteristics of each pairs of trade partner countries the endogeneity of some of the explanatory variables as well as a potential selection bias in contrast to previous estimates results show that regional agreements have generated a significant increase in trade between members often at the expense of the rest of the world

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

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

risk spillover of international crude oil to china s firms evidence from granger causality across quantile abstract this paper investigates the extreme risk spillover of international crude oil to stock returns for 529 firms listed on the a share market of the shanghai stock exchange we apply a kernel based nonparametric method to test quantile on quantile granger causality from crude oil to firm returns from the perspective of firm level analysis the findings are outlined as follows first our empirical results provide strong evidence to suggest the asymmetry in the linkage of extreme movements from crude oil to firm returns that is the case of positive risk spillovers are more severe than the case of negative risk spillovers in particular the down to down risk spillover is the most serious case this phenomenon unravels the strong driving force of economic cycles second risk transmission from oil price shocks to firm returns depends on the firm s industry features in addition to the usual focus on inter industry difference we also note the within industry heterogeneity third we confirm that china s refined oil pricing reform of march 27 2013 has had intensifying effects on the negative spillovers from oil prices to firms for investors we emphasize not only the awareness of the predictive power between extreme risks from international crude oil to china s firms but also the existence of heterogeneity in these predictive abilities across firms

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

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

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

self confirming equilibrium and the lucas critique we examine the role of off path superstitions in macro economics and show how a false belief about off path play is the key element underlying both the lucas critique and the game theoretic concept of self confirming equilibrium however the impact of false beliefs in these two cases is different in the lucas case a policy maker s incorrect beliefs about off path play can lead to the adoption of mistaken policy innovation however the consequences of such an innovation provide evidence that the belief that motivated them was wrong in contrast play may never escape an undesirable self confirming equilibrium as the action implied by the mistaken belief does not generate data that contradicts it escape from the self confirming equilibrium requires that players do a sufficient amount of experimentation with off path actions

on the origins of gender roles women and the plough the study examines the historical origins of existing cross cultural differences in beliefs and values regarding the appropriate role of women in society we test the hypothesis that traditional agricultural practices influenced the historical gender division of labor and the evolution of gender norms we find that consistent with existing hypotheses the descendants of societies that traditionally practiced plough agriculture today have less equal gender norms measured using reported gender role attitudes and female participation in the workplace politics and entrepreneurial activities our results hold looking across countries across districts within countries and across ethnicities within districts to test for the importance of cultural persistence we examine the children of immigrants living in europe and the united states we find that even among these individuals all born and raised in the same country those with a heritage of traditional plough use exhibit less equal beliefs about gender roles today jel codes d03 j16 n30 copyright 2013 oxford university press

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

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

oil shocks competition and corporate investment evidence from china abstract this paper aims to investigate the impact of three classical oil shocks on the chinese corporate investment by using firm level data moreover we assess the role of product market competition in the relationship between oil shocks and corporate investment our empirical results show that oil aggregate demand and specific demand shocks negatively affect corporate investment while oil supply shocks show a positive effect notably compared to the non energy related industry the corporate investment of energy related industry is more sensitive to these oil shocks furthermore we find high competitive pressure can mitigate the impact of oil specific demand shocks on the corporate investment of energy related industry but competition presents a limited effect on the relationship between other oil shocks and corporate investment

the link between green taxation and economic growth on co2 emissions fresh evidence from malaysia abstract this paper explores how carbon taxation and economic growth affect environment hazards in malaysia using time series data over the period 1974 2010 we applied cointegration and causality approaches to determine the long term cointegration and direction of causal relationship between these variables based on the results we found the cointegration relationship between the variables furthermore we noted that although kuznets theory i e inverted u shaped curve between economic growth and co 2 emissions is valid for malaysia the carbon taxation policy is ineffective to control co 2 emissions the causality analysis revealed that there is a bidirectional relationship between carbon tax and co 2 emissions economic growth granger causes co 2 emissions and carbon tax granger causes economic growth to enhance the awareness concerning pollution issues governments should rely on alternative instruments that may give benefit to the taxpayers and reduce pollution which is the pivotal issue to be tackled globally

dynamic gravity endogenous country size and asset accumulation the gravity equation is the most successful and celebrated empirical model in international trade over the past decade numerous gravity applications have resorted to panel data econometric techniques in order to account for the intrinsically dynamic nature of trade data with the theory of gravity being so far only static these empirical estimations lack solid structural foundations as a consequence a consensus on a unied dynamic gravity estimation approach is yet to be reached the contribution of this paper is threefold first we build a theoretical foundation for the gravity model in a dynamic setting second we use our structural framework to provide clear empirical implications for gravity type estimations with panel data and we consider applications finally to better understand the eect of trade policy in this dynamic framework we calibrate and numerically simulate our general equilibrium model and we compare its properties to those of the standard static gravity model

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

quantile dependence of oil price movements and stock returns we examine the impact of quantile and interquantile oil price movements on different stock return quantiles by testing the hypothesis of equality in conditional and unconditional quantile distribution functions of stock returns we capture quantile dependence under different stock market conditions while taking into account different kinds of oil price movements by computing unconditional and conditional stock return quantiles through marginal models for stock returns and copula functions for oil stock dependence analyzing stock return data for three developed economies the us the uk and the european monetary union and the five brics countries brazil russia india china and south africa for 2000 to 2014 our results indicate that 1 the impact of extreme upward and downward oil price changes on upper and lower stock price quantiles was much smaller before compared to after crisis onset 2 the downside spillover effects were larger than the upside spillover effects for most countries before crisis onset and for all countries after crisis onset and 3 small positive and negative oil price movements had no impact on any stock return quantiles neither before nor after crisis onset

measuring contagion between energy market and stock market during financial crisis a copula approach abstract in this paper we apply time varying copulas to investigate whether a contagion effect existed between energy and stock markets during the recent financial crisis using the wti oil spot price the s p500 index the shanghai stock market composite index and the shenzhen stock market component index returns evidence was found for a significantly increasing dependence between crude oil and stock markets after the failure of lehman brothers thus supporting the existence of contagion in the sense of forbes and rigobon s 2002 definition moreover increased tail dependence and symmetry characterize all the paired markets this indicates that significant increases in tail dependence are an actual dimension of the contagion phenomenon and that crude oil and stock prices are linked to the same degree regardless of whether markets are booming or crashing during the sample period finally the contagion effect is found to be much weaker for china than the us the empirical results have potentially important implications for risk management

witchcraft beliefs as a cultural legacy of the atlantic slave trade evidence from two continents abstract this paper argues that the historical slave trade contributed to the propagation of persistent witchcraft beliefs on both sides of the atlantic ocean and establishes two key empirical patterns first it shows that in sub saharan africa representatives of ethnic groups which were more heavily exposed to the atlantic slave trade in the past are more likely to believe in witchcraft today thus establishing a link between historical trauma and contemporary culture second exploring the role of the slave trade in cultural transmission across continents this paper finds that afro descendants in modern latin america are substantially more likely to believe in witchcraft relative to other ancestral groups moreover accounting for ancestry and other relevant factors people residing in regions historically more reliant on african slave labor are also more likely to be witchcraft believers these findings support ethnographic narratives on the connection between slave trade slavery and the entrenchment of witchcraft beliefs and shed light on the nature of these beliefs and related practices as a cultural framework for interpreting misfortune and a mechanism of enslavement in local communities

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

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

sectoral exposure of financial markets to oil risk factors in brics countries abstract in this paper we examine the exposure of sectoral equity returns to changes in oil risk factors among brics markets the paper combines var model together with the random forest technique to provide a novel framework which overcome some weaknesses in var modelling and help in the selection of oil risk factors considered our results in general show that the response of sectoral stocks to changes in oil risk factors is not homogenous and their sensitivities are not uniform across brics markets stock returns of basic materials financials and industrials sectors show consistently negative sensitivity to crude oil volatility ovx and oil price shocks for major oil importers whereas sectoral stocks among major oil exporters seems to demonstrate systematic pattern to explain sectoral stock variations the results reveal ovx and oil to be the most significant risk transmitting factors in brics irrespective of whether the market is a major oil importer or exporter however our results also confirm the presence of asymmetric effects in sectoral stocks for brazil and russia while no such evidence is found for india china and south africa overall the findings suggest that the manner in which sectors respond to fluctuations in oil risk factors varies between different sectors and it depends on the oil characteristics of the markets nature of sectors and the type of oil risk factors considered

china s one belt one road initiative the impact of trade facilitation versus physical infrastructure on exports the one belt one road obor project is perhaps china s most significant international relations initiative in recent times it is based on openness harmony inclusivity mutual benefit and market operations and aims to connect the economically vibrant east asia and the developed europe by land and by sea and in the process it brings growth and development to tens of countries along the modern silk routes in this paper we compare the impact of the main initiatives of obor namely enhancements in physical infrastructure and improvements in border administration on the trade of countries that have signed on to this project especially countries along the six economic corridors we find overwhelming evidence that shows improvements in border administration has the greatest impact on exports of corridor countries although physical infrastructure is important for trade the chinese government should place equal attention to improvements in trade facilitation to ensure trade routes operate seamlessly across the various corridors

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

the effects of crude oil shocks on stock market shifts behaviour a regime switching approach abstract in this paper we develop a two regime markov switching egarch model introduced by henry henry o 2009 regime switching in the relationship between equity returns and short term interest rates journal of banking and finance 33 405 414 to examine the relationship between crude oil shocks and stock markets an application to stock markets of uk france and japan over the sample period january 1989 to december 2007 illustrates plausible results we detect two episodes of series behaviour one relative to low mean high variance regime and the other to high mean low variance regime furthermore there is evidence that common recessions coincide with the low mean high variance regime in addition we allow both real stock returns and probability of transitions from one regime to another to depend on the net oil price increase variable the findings show that rises in oil price has a significant role in determining both the volatility of stock returns and the probability of transition across regimes

asymmetric effects of oil price shocks on stock returns evidence from a two stage markov regime switching approach abstractthe asymmetric effects of oil price shocks on stock returns have attracted the attention of many researchers in the past several decades most of these researchers studies however do not separate out the sources of oil price shocks when examining the asymmetric effects in this article we address this limitation using a two stage markov regime switching approach our results indicate that oil supply and demand shocks have a null or minimal impact on stock returns in a low volatility regime and a statistically significant impact in a high volatility regime we observe that oil demand shocks affect stock returns significantly more than oil supply shocks a positive aggregate demand shock significantly increases stock returns whereas a positive oil specific demand shock markedly decreases stock returns these results have important implications for policymakers and investors

this is what happened to the oil price macroeconomy relationship abstract many of the quarterly oil price increases observed since 1985 are corrections to even bigger oil price decreases the previous quarter when one looks at the net increase in oil prices over the year recent data are consistent with the historical correlation between oil shocks and recessions

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

oil price shocks stock market economic activity and employment in greece abstract using a multivariate vector autoregression var approach this paper attempts to shed light into the dynamic relationship among oil prices real stock prices interest rates real economic activity and employment for greece the empirical evidence suggests that oil price changes affect real economic activity and employment oil prices are important in explaining stock price movements stock returns do not lead to changes in real activity and employment

financial stability energy consumption and environmental quality evidence from south asian economies abstract a few studies are found on the relationship between financial instability energy consumption and environmental quality in energy economics literature the current study is an endeavor to fill this gap by investigating the relationship between financial stability economic growth energy consumption and carbon dioxide co 2 emissions in south asian countries over the period 1980 2012 using a multivariate framework bounds test for cointegration and granger causality approach are employed for the empirical analysis estimated results suggest that all variables are non stationary and cointegrated the results show that financial stability improves environmental quality while the increase in economic growth energy consumption and population density are detrimental for environment quality in the long run the results also support the environmental kuznets curve ekc hypothesis which assumes an inverted u shaped path between income and environmental quality moreover the study found the evidence of unidirectional causality running from financial stability to co 2 emissions in two countries i e pakistan and sri lanka the findings of this study open up new insight for policy makers to design a comprehensive financial economic and energy supply policies to minimize the detrimental impact of environmental pollution

does aid for trade enhance export performance investigating on the infrastructure channel today there are few empirical studies assessing the effectiveness of aid for trade on trade pe rformance furthermore existing works do not test channels by which this impact is transiting we address this question using an empirical analysis constructed in two steps following a model of export performance we first test if institutions and infrastructure our two potential channels of transmission are indeed determinants of export performance secondly we test the impact of aid for trade sectoral flows on the determinants that were highlighted in the first part we show that the infrastructure channel appears to be highly significant in the first step whereas the institutional one turns out to have limited impact on developing countries exports furthermore in our second step aid for infrastructure seems once instrumented to have a strong and positive impact on the infrastructure level our results indicate that a 10 increase in aid to infrastructure commitments per capita leads to an average increase of the exports over gdp ratio for a developing country of 2 34 it is also equivalent to a 2 71 reduction of the tariff and non tariff barriers this highlights the very high economic impact of aid for trade throughout the channel of infrastructures

the role of renewable energy consumption in economic growth evidence from asymmetric causality abstract this paper investigates the causality among economic growth renewable energy consumption capital and labor for new eu member countries for the period of 1990 2009 by using asymmetric causality test approach and autoregressive distributed lag ardl approach the empirical results support that renewable energy consumption has positive impacts on economic growth for all investigated countries but only for bulgaria estonia poland and slovenia there is statistically significant impact on economic growth has found and also supports neutrality hypothesis for cyprus estonia hungary poland and slovenia while the conservation hypothesis is present for czech republic the fact that there is a causal relationship from economic growth to renewable energy consumption and the growth hypothesis is supported for bulgaria referring to causality from energy consumption to economic growth

volatility spillovers between crude oil and chinese sectoral equity markets evidence from a frequency dynamics perspective abstract we examine the frequency dynamics of volatility spillovers between crude oil and china s stock markets in a spectral representation framework of generalized forecast error variance decomposition using sectoral stock indices data we find evidence of total volatility spillover driven mainly by short term spillovers the net spillovers of the oil market are almost all positive and dominated by short ter m components although the spillover during china s 2015 financial crisis is negative and attributable to long term components in addition there exists heterogeneity in net pairwise frequency spillovers between the oil and sectoral stock markets moreover structural breaks in volatilities appear to be a significant feature of volatility spillovers finally frequency spillovers in our system can predict future stock market volatility these results have economic implications for investors and policymakers

asymmetric impact of oil price on islamic sectoral stocks abstract this paper extends the literature concerning non linearity in oil stock relationships by putting forward a new paradigm of sectoral and islamic elements we explore the asymmetric impact of oil price on islamic stocks from a sectoral perspective using non linear autoregressive distributed lag cointegration methodology the main advantage of this methodology relies on its ability to simultaneously capture the short and long run asymmetries through both positive and negative oil price shocks our results show weak linkages between oil price changes and the islamic composite index however the nature and sensitivity of the reaction of stock prices to oil price shocks vary considerably across different sectors in the longer horizon the relationships between oil price and many islamic sectoral stocks tend to follow a nonlinear pattern furthermore the behavior of the real economic sectors indices reflects the performance of the composite index that is oil price resistant during the turbulent period after 2008 the response of the sectoral indices to oil price movements witnessed notable changes where the sectoral gains from oil price drop that have been observed during the period of study have been found to diminish after 2008 our finding is in line with the argument that the islamic composite index is grounded more on and within the real sectors these findings are robust when considering different oil proxies and different data time frequencies

modelling the conditional volatility of commodity index futures as a regime switching process commodity index futures offer a versatile tool for gaining different forms of exposure to commodity markets volatility is a critical input in many of these applications this paper examines issues in modelling the conditional variance of futures returns based on the goldman sachs commodity index gsci given that commodity markets tend to be choppy webb 1987 a general econometric model is proposed that allows for abrupt changes or regime shifts in volatility transition probabilities which vary explicitly with observable fundamentals such as the basis garch dynamics seasonal variations and conditional leptokurtosis the model is applied to daily futures returns on the gsci over 1992 1997 the results show clear evidence of regime shifts in conditional mean and volatility once regime shifts are accounted for garch effects are minimal consistent with the theory of storage returns are more likely to switch to the high variance state when the basis is negative than when the basis is positive the regime switching model also performs well in forecasting the daily volatility compared to standard garch models without regime switches the model should be of interest to sophisticated traders who base their trading strategies on short term volatility movements managed commodity funds interested in hedging an underlying diversified portfolio of commodities and investors of options and other derivatives tied to gsci futures contracts copyright 2001 john wiley sons ltd

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

impacts of opec s political risk on the international crude oil prices an empirical analysis based on the svar models abstract the impacts of opec s political risk on the fluctuations of international crude oil prices have caused widespread concern and analyzing the impacts is of great significance to the investment decisions and risk aversion strategies in the crude oil markets therefore using the international country risk guide icrg index as a proxy for the countries political risk situation we empirically investigate the impacts of opec s political risk on the brent crude oil prices based on several structural vector autoregression svar models the main empirical results indicate that 1 the political risk of opec countries does have a significant and positive influence on brent crude oil prices in the sample period from january 1998 to september 2014 and the most significant positive influences appear in about one and a half year and last about a year 2 opec s integrated political risk contributes to 17 58 of the oil price fluctuations in the sample period which is only lesser than that of the oil demand shocks 34 64 3 compared with the political risk of opec countries in north africa and south america the political risk of opec countries in the middle east contributes most to the oil price fluctuations 4 among the eight components of the political risk in opec the internal conflicts contribute most to the oil price fluctuations in the sample period

the impact of crude oil prices on financial market indicators copula approach abstract oil price changes have varying impacts on the financial indicators of global markets and economies this study aims to explore the dependence structure between crude oil prices and stock market indices as well as the exchange rates in a number of economies categorized with respect to their status as developing emerging markets and oil importer exporter countries dependence structures in this study are evaluated in considerable depth using copula models the broad time period covered allows the investigation of the effect of global financial crisis on the mentioned dependence structure an additional feature of this study is the inclusion of 1 to 30 day analysis to capture the variation of dependence on duration change to serve these aims as well as arima and garch models various copula measures are used to illustrate the level of the association additionally a special focus on the turkish case is given to illustrate its sensitivity to oil prices we find that exchange rates and stock indices of most oil exporter countries show higher oil price dependency whereas emerging oil importer markets are less vulnerable to price fluctuations considerable impacts were found for the global crisis and the continuing recent sharp decrease in oil prices

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

export performance and trade facilitation reform hard and soft infrastructure summary we estimate the impact of aggregate indicators of soft and hard infrastructure on the export performance of developing countries we derive four new indicators for more than 100 countries over the period 2004 07 estimates show that trade facilitation reforms do improve the export performance of developing countries this is particularly true with investment in physical infrastructure and regulatory reform to improve the business environment the findings provide evidence that the marginal effect of the transport efficiency and business environment improvement on exports appears to be decreasing in per capita income in contrast the impact of physical infrastructure and information and communications technology on exports appears increasingly important the richer a country becomes we also find statistical evidence on the complementarity between hard infrastructure and soft infrastructure as captured by our indicators finally drawing on estimates we compute illustrative ad valorem equivalents of improving each indicator halfway to the level of the top performer in the region

crude oil and the macroeconomy tests of some popular notions a note perhaps no other economic events in the post world war ii era have generated as much attention as the series of crude oil price shocks that have jolted the world economy since the opec boycott of 1973 a tremendous amount of space in the popular and professional literature has been devoted to analyzing the impacts of these shocks on the developed economies and the adjustments these shocks have induced one residual of this literature has been a general impression that since 1973 the functional relationship between crude oil prices and the developed macroeconomies has been dramatically and fundamentally altered yet to our knowledge no one has formally tested this impression recent evidence of hamilton 1983 suggests that crude oil prices had a strong impact on the u s business cycle well before 1973 further while textbook treatments of oil price shocks tend to highlight cost push inflationary effects the research of berndt and wood 1975 1979 and wilcox 1983 indicates the net complementarity between energy and capital in the u s economy is quite strong both before and after 1973 thus oil price shocks may have stronger real effects than generally believed in this paper we formally test three popular notions associated with the so called

oil prices and real exchange rates in this paper we investigate the long run relationship between real oil prices and real exchange rates by using a monthly panel of g7 countries from 1972 1 to 2005 10 we first test whether exchange rates are cointegrated with real oil prices it is shown that real oil prices may have been the dominant source of real exchange rate movements and that there is a link between real oil prices and real exchange rates we then examine the ability of real oil prices to forecast future real exchange returns panel predictive regression estimates suggest that real oil prices have significant forecasting power the out of sample prediction performances demonstrate greater predictability over longer horizons

volatility regimes asymmetric basis effects and forecasting performance an empirical investigation of the wti crude oil futures market abstract this study employs a flexible regime switching egarch model with student t distributed error terms to investigate whether volatility regimes and basis affect the behavior of crude oil futures returns including the conditional mean variance skewness kurtosis as well as the extent of heavy tailedness the study also examines whether volatility regimes and asymmetric basis effects can improve the forecasting accuracy the main merit of the empirical model is that the basis effect is allowed to be asymmetric and to vary across volatility regimes empirical results suggest that the conditional mean and variance respond to the basis asymmetrically and nonlinearly and that the responses of transition probabilities to the basis are symmetric furthermore the conditional higher moments are sensitive to the absolute value of basis and the heavy tailed characteristic can be greatly alleviated by taking into account the asymmetric basis effects and regime switches finally the regime switches and asymmetric basis effects play decisive roles in forecasting return volatility and tail distribution

the dynamic effects of oil supply shocks on the us stock market returns of upstream oil and gas companies abstract a time varying parameter var model is used to examine the impact of structural oil supply shocks on the us real stock market return of oil and gas exploration and production companies the result shows that the impact response of the real return of the upstream stocks to a negative world non us oil supply shock increases substantially over recent years from an average value of 0 70 in 2006 to 6 16 during 2008 2010 with a spike of 6 81 in 2014q3 the endogenous effects of us oil supply shocks on the return play an important role in that the responses of the stock returns to a negative us oil supply shock are positive and persistent with an average value of 3 60 over time the time varying effects of oil supply shocks are heterogeneous the magnitudes of return responses are different among independents large proved reserve independents and integrated companies over time

how do china s petrochemical markets react to oil price jumps a comparative analysis of stocks and commodities abstract the profound impacts of oil price jumps have caught the attention of scholars because the 2008 global financial crisis has seemingly already passed the existence of oil price jumps is in doubt in this paper we provide evidence that the threat of dynamic jumps still exists in the global oil market in the post crisis period while the stocks and commodities of china s petrochemical markets are both affected by those jumps to the best of our knowledge this is the first study of the reaction of petrochemical markets to oil price jumps in the post crisis period in addition a comparative analysis of petrochemical stocks and petrochemical commodity market is provided in particular we analyze the reactions of the returns and volatility of these markets to oil price jumps we obtained the following findings first the returns of petrochemical stocks and petrochemical commodities are both negatively affected by current oil price jumps while the effects of lagged jumps on these returns are opposite theoretically the former is a reflection of panic induced by extreme risk information while the latter is a reflection of rationality in speculators second the volatilities of petrochemical stocks and petrochemical commodities respond differently to oil price jumps the former is not affected whereas the latter is positively and negatively affected by current and last oil price jumps respectively finally all the above conclusions still hold when considering the effects of normal oil price volatility even after the co movement between oil prices and petrochemical markets is eliminated

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

do higher oil prices push the stock market into bear territory this paper investigates whether a higher oil price pushes the stock market into bear territory by using time varying transition probability markov switching models it examines different measures of oil price shocks empirical evidence from monthly returns on the standard poor s s p 500 price index suggests that an increase in oil prices leads to a higher probability of a bear market emerging

measuring the reaction of monetary policy to the stock market movements in the stock market can have a significant impact on the macroeconomy and are therefore likely to be an important factor in the determination of monetary policy however little is known about the magnitude of the federal reserve s reaction to the stock market in part because the simultaneous response of equity prices to interest rates makes it difficult to estimate this paper uses an identification technique based on the heteroskedasticity of stock market returns to measure the reaction of monetary policy to the stock market we find a significant policy response with a 5 percent rise fall in the s p 500 index increasing the likelihood of a 25 basis point tightening easing by about a half

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

quantile relationship between oil and stock returns evidence from emerging and frontier stock markets abstract this study extends the literature on the asymmetric effect of oil price fluctuations on emerging and frontier stock markets via a quantile on quantile approach that allows to capture normal and extreme states in each respective market we find that oil risk exposures are heterogeneous across the emerging and frontier stock markets and indeed display quantile specific characteristics observing uniform patterns of oil risk exposures within groups of countries that include both importers and exporters we argue that oil price risk serves as a systematic risk proxy capturing the market s concerns regarding global growth expectations rather than a simple import export commodity our findings suggest that signals from the oil market either via measures of trading activity in oil futures or changes in basis values could be utilized by policy makers to improve models of stock market volatility

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

an econometric view on the estimation of gravity models and the calculation of trade potentials this paper presents an ar 1 model in the spirit of hausman and taylor zero differences between actual and in sample predicted trade flows large systematic differences between observed and in sample predicted trade flows only indicate model misspecification and econometric problems out of sample predictions make sense if countries of interest are in an early stage of the transformation process the gravity model remains an interesting tool for the calculation of counterfactuals e g the impact of catching up in gdp per capita in the ceec or of the reduction of trade costs via infrastructure investments or tariffs on bilateral trade etc for this line of research the difference between short term and long term influences could provide interesting insights

openness to trade in manufactures in the oecd abstract how open are the advanced economies to trade with each other in this paper openness is calculated relative to the predictions of the monopolistic competition trade model using data on manufacturing trade and production in the oecd in 1985 the paper finds that 1 japan imports much less than other large oecd countries while the european countries have larger import volumes than does the us 2 japan and the us engage in less intra industry trade than the rest of the oecd and 3 the eu countries are less open to imports from japan and the us than those countries are open to imports from the eu

the slave trade and the origins of mistrust in africa in a recent study nunn 2008 examines the long term impacts of africa s slave trade he finds that the slave trade which occurred over a period of more than 400 years had a significant negative effect on long term economic development although the article arguably identifies a negative causal relationship between the slave trade and income today the analysis is unable to establish the exact causal mechanisms underlying this reduced form relationship in this article we examine one of the channels through which the slave trade may affect economic development today combining contemporary individual level survey data with historical data on slave shipments by ethnic group we ask whether the slave trade caused a culture of mistrust to develop within africa initially slaves were captured primarily through state organized raids and warfare but as the trade progressed the environment of ubiquitous insecurity caused individuals to turn on others including friends and family members and to kidnap trick and sell each other into slavery sigismund wilhelm koelle 1854 p e h hair 1965 charles piot 1996 we hypothesize that in this environment a culture of mistrust may have evolved which may persist to this day we show that current differences in trust levels within africa can be traced back to the transatlantic and indian ocean slave trades combining contemporary individual level survey data with historical data on slave shipments by ethnic group we find that individuals whose ancestors were heavily raided during the slave trade are less trusting today evidence from a variety of identification strategies suggests that the relationship is causal examining causal mechanisms we show that most of the impact of the slave trade is through factors that are internal to the individual such as cultural norms beliefs and values jel j15 n57 z13

time varying volatility spillover between chinese fuel oil and stock index futures markets based on a dcc garch model with a semi nonparametric approach abstract this paper reveals some new evidence on the volatility spillover between fuel oil and stock index futures markets in china by considering its time variant feature time varying effect is specified by the legendre polynomials in a dcc garch model moreover the semi nonparametric snp approach accounting for marginal excess kurtosis and asymmetry is applied we find different time evolving patterns of volatility spillover across multiple periods due to the structural breaks the direction of mean volatility spillover is found to be bilateral moreover the strength of mean volatility spillover shows that the effect from stock index to fuel oil futures is much stronger than the other way around this implies that the stock index futures market plays a leading role in information processing these findings have important implications for the fuel oil stakeholders as well as risk management

the economic origins of the evil eye belief the evil eye belief is a widespread superstition according to which people can cause harm by a mere envious glance at coveted objects or their owners this paper argues that such belief originated and persisted as a useful heuristic under conditions in which envy was likely to trigger destructive behavior and the avoidance of other people s envy effectively prescribed by the evil eye belief was a proper response to that threat we hypothesize that in weakly institutionalized societies wealth differentiation and vulnerability of productive assets were the key factors enabling envy induced destructive behavior and contributing to the emergence and spread of the evil eye belief as a cultural defense mechanism evidence from small scale preindustrial societies shows that there is indeed a robust positive association between the incidence of the belief and measures of wealth inequality controlling for potential confounding factors such as patterns of spatial and cross cultural diffusion and various dimensions of early economic development furthermore the evil eye belief is more prevalent in agro pastoral societies that tend to sustain higher levels of inequality and where vulnerable material wealth plays a dominant role in the subsistence economy

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

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

oil and the macroeconomy since the 1970s economists have long been intrigued by empirical evidence that suggests that oil price shocks may be closely related to macroeconomic performance this interest dates back to the 1970s the 1970s were a period of growing dependence on imported oil unprecedented disruptions in the global oil market and poor macroeconomic performance in the united states thus it was natural to suspect a causal relationship from oil prices to u s macroeconomic aggregates since then a large body of work has accumulated that purports to establish this link on theoretical grounds and to provide empirical evidence in its support we do not attempt a comprehensive survey of this literature but rather provide an idiosyncratic synthesis of what we view as the key issues in this debate and the insights gained over the last 30 years the timing seems right for such an account although the experience of the 1970s continues to play an important role in discussions of the link between oil and the macroeconomy there have been a number of new oil price shocks since the 1970s notably the 1986 collapse of oil prices and the 2000 boom in oil prices as well as the oil price increases associated with the 1990 1991 gulf war and the 2003 iraq war given this richer case history we are arguably in a better position than two decades ago to distinguish the idiosyncratic features of each oil crisis from the systematic effects increases in oil prices have been held responsible for recessions periods of excessive inflation reduced productivity and lower economic growth in this paper we review the arguments supporting such views first we highlight some of the conceptual difficulties in assigning a central role to oil price shocks in explaining

how bad is antidumping evidence from panel data abstract current research on antidumping suggests a number of channels through which antidumping affects the volume of world trade this paper uses a structural approach to the gravity model framework to evaluate these hypotheses using data on trade volume over the period 1948 to 2001 we conclude that the volume and welfare effects have been negative but quite modest

dynamics and stagnation in the malthusian epoch this paper examines the central hypothesis of the influential malthusian theory according to which improvements in the technological environment during the pre industrial era had generated only temporary gains in income per capita eventually leading to a larger but not significantly richer population exploiting exogenous sources of cross country variations in land productivity and the level of technological advancement the analysis demonstrates that in accordance with the theory technological superiority and higher land productivity had significant positive effects on population density but insignificant effects on the standard of living during the time period 1 1500 ce

relative price variability real shocks and the stock market in this paper we investigate the effects of relative price variability on output and the stock market and gauge the extent to which inflation proxies for relative price variability in stock return inflation regressions the evidence shows that the negative stock returninflation relations proxy for the adverse effects of relative price variability on economic activity particularly during the seventies when the u s experienced oil supply shocks hence it appears that inflation spuriously affects the stock market in two ways the aggregate output link of fama 1981 and the supply shocks reflected in relative price variability a number of papers have attempted to explain the anomalous negative relations between stock returns and inflation witnessed in the post war period one hypothesis that has held up well in light of empirical evidence suggests that the negative relation between stock returns and unexpected inflation simply reflects the more fundamental positive relation between stock returns and future real variables see e g fama 1981 geske and roll 1983 and kaul 1987 1989 in this paper we investigate the effects of relative price variability on output and the stock market and gauge the extent to which inflation proxies for relative price variability in stock return inflation regressions first relative price variability can have detrimental effects on output and employment see e g friedman 1977 and barro 1976 second absolute relative price confusion models of the lucas 1973 type suggest that monetary shocks can induce a positive relation between inflation and relative price variability see e g cukierman 1983 hence the negative stock return inflation relations could simply be a reflection of the negative effects of relative price variability on the stock market we use data for the 1947 1985 period to test the various links of our hypothesis the results indicate that relative price variability is positively related to both expected and unexpected inflation measures relative price variability also has a significant negative effect on output and the stock market more importantly

stock prices of clean energy firms oil and carbon markets a vector autoregressive analysis recent discussions of energy security and climate change have attracted significant attention to clean energy we hypothesize that rising prices of conventional energy and or placement of a price on carbon emissions would encourage investments in clean energy firms the data from three clean energy indices show that oil prices and technology stock prices separately affect the stock prices of clean energy firms however the data fail to demonstrate a significant relationship between carbon prices and the stock prices of the firms

the influence of the international oil prices on the real effective exchange rate in romania in a wavelet transform framework article i nfo the purpose of this paper is to assess the empirical influence of oil prices on the real effective exchange rate in romania in a wavelet transform framework more precisely we investigate to what extent oil prices impact the real effective exchange rate in an eastern european transition country characterised by a low level of retail fuel prices and by an important growth rate of these prices as compared to the other eu countries for this purpose we use a discrete wavelet transform approach and scale by scale granger causality tests we find that oil prices have a strong influence on the real effective exchange rate in the short run but also for large time horizons these results are important considering the fact that in a classical granger causality linear framework for the entire sample we find that oil prices have no influence on the real effective exchange rate the findings remainrobust whenresampling the initial 1986 2009period orwhen weuse analternative continuous wavelet transform in addition we discover that mainly the positive shocks associated with an increase in oil prices have an impact upon the real effective exchange rate movements in the short and long runs

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
