Relationships among U.S. oil prices and oil industry equity indices

The cointegration analysis suggests that the pure oil industry equity system and the mixed oil price/equity index system offers more opportunities for long-run portfolio diversification and less market integration than the pure oil price systems. On a daily basis, in the oil price systems all oil prices with the exception of the 3-month futures can explain the future movements of each other. In the mixed system, none of the daily oil industry stock indices can explain the daily future movements of the New York Mercantile Exchange (NYMEX) futures prices, whereas these prices can explain the movements of independent companies engaged in exploration, refining, and marketing. The spillover analysis of oil volatility transmission suggests that the oil futures market has a matching or echoing volatility effect on the stocks of some oil sectors and a volatility-dampening effect on the stocks of others. The policy implication is that, during times of high oil volatility, traders should choose the S&P oil sector stocks that match their tolerance for volatility and use the right financial derivative to hedge against or profit from this volatility. The day effect for volatility transmission suggests that Friday has a calming effect on the volatility of oil stocks in general. The effect for Monday is not significant.     

Oil prices,growth, and remittance outflows from the Gulf Cooperation Council

How does a decline in oil prices and its impacts on growth affect remittance outflows from the Gulf Cooperation Council (GCC) countries? This paper carries out an empirical analysis of the relationship between oil prices, oil‐ and non‐oil GDP, and remittances outflows from the GCC. The findings of our paper are three folds. First, we find that non‐oil GDP is a key determinant of remittance outflows and that oil GDP is a significant driver of non‐oil GDP in the GCC only in the long term. Second, we document that historically oil prices and remittances tend to broadly move in the same direction but that remittances have been much less volatile than oil prices. An analysis of the past large oil price declines shows that remittance flows to major remittance recipients in Mashreq, Pakistan, and Yemen fell only modestly following large declines in oil prices and recovered quickly in line with oil prices. Finally, we estimate the elasticity of remittance outflows with respect to non‐oil GDP in the GCC using various techniques. Estimates of short‐term elasticity vary between 0.5 and 0.8, while estimates of long‐term elasticity vary between 0.6 and 1.1. We find that construction and government services are two non‐oil GDP components that are strongly associated with remittance outflows.

Optimal oil taxation in a small open economy

The international oil market has been very volatile over the past three decades. In industrialized economies, especially in Europe, taxes represent a large fraction of oil prices and governments do not seem to react to oil price shocks by using oil taxes strategically. The aim of this paper is to analyze optimal oil taxation in a dynamic stochastic general equilibrium model of a small open economy that imports oil. We find that in general it is not optimal to distort the oil price paid by firms with taxes, neither in the long run nor over the business cycle. The general result could be reversed depending on environmental considerations and available fiscal instruments. We provide simulations to illustrate the optimal response to shocks in such cases.     

Long-term implications of oil discoveries for international saving in a DSGE model

Possession and production of oil reserves affects the host country’s current account. Throughout the history of the North Sea oil, Norway ran persistent current account surpluses and accumulated public “oil funds.” The other major producer, the United Kingdom did not establish an oil fund. This work models how oil discoveries impact the current account. A small open economy DSGE model with an oil sector expresses the current account as a function of oil discoveries. In this model, an oil discovery creates a long-term borrowing-repayment-saving cycle. Some of the characteristics of the economy that affect oil-related decisions include: the presence of an oil fund, the equity home bias, and the technology of the oil industry. These characteristics are estimated structurally using the North Sea data for Norway and the United Kingdom. The estimation suggests that, upon discovering oil in the North Sea, the populations of Norway and the United Kingdom made similar economic choices but under different circumstances: Norway’s export revenues were amplified by a period of high oil prices in the 2000s, whereas the UK largely balanced its oil trade and did not benefit from the oil price. Similar decisions made under different circumstances led to remarkably different effects of oil discoveries on the current accounts.     

Does international oil volatility have directional predictability for stock returns? Evidence from BRICS countries based on cross-quantilogram analysis

While numerous studies have investigated the relationship between oil volatility and stock returns, it is surprising that little research has examined the quantile dependence and directional predictability from oil volatility to stock returns in BRICS (Brazil, Russia, India, China, and South Africa) countries. We address this issue by using the cross-quantilogram model proposed by Han et al. (2016). The empirical results show that, overall, oil volatility has a directional predictability for the stock returns in BRICS countries. When the oil volatility is in a low quantile (lower than its 0.1 quantiles), it is less likely to show either a large loss or a large gain in the stock market. In contrast, there is an increased likelihood of either large loss or a large gain in the stock market when the oil volatility is in a high quantile (higher than its 0.9 quantiles). The directional predictability from the oil volatility to stock returns depends on the net position of oil imports and exports of these BRICS countries in the oil market. The net oil exporters (Russia and Brazil) are less likely to have large gains and large losses in the stock market than are the net oil importers (India, China, and South Africa) when the oil volatility is in a low quantile. The net oil exporters are more likely to have large gains and large losses than are the net oil importers when the oil volatility is in a high quantile. The results are robust to change in the variable of oil volatility and the sample interval.     

MACROECONOMIC EFFECTS OF THE 1986 OIL PRICE DECLINE

The oil price decline during 1986 sparked a renewed debate over how oil price changes affect the economy and whether the effects of oil price declines are equal and opposite those of oil price increases. This article reviews theoretical and more casual arguments concerning this issue and describes some tests rejecting the hypothesis that the effects of oil price declines are asymmetric to those of oil price increases.     

HOW DO OIL PRICE SHOCKS AFFECT A SMALL NON‐OIL PRODUCING ECONOMY? EVIDENCE FROM HONG KONG

We find no evidence from either in‐sample or out‐of‐sample analyses that an oil price shock would necessarily affect a small non‐oil producing economy such as Hong Kong. In our in‐sample recursive vector autoregressive investigations, oil price does not Granger cause the key macroeconomic indicators. The forecast errors from our out‐of‐sample examination using a vector error correction model with oil shocks, which represents an extension to previous studies, were found to be statistically the same as those from the vector error correction model without these shocks. The analysis leads us to dispel the conventional wisdom that a small non‐oil producing economy is more vulnerable to oil shocks than a larger oil‐producing economy such as the USA.     

An investigation into the dynamic relationship between international and China’s crude oil prices

This article studies the dynamic relationship between international (WTI, Brent and Dubai) and domestic (Da Qing) crude oil prices in China using threshold cointegration method. We find evidence of a long-run equilibrium relationship between each pair of international and Da Qing oil prices, favouring the market integration hypothesis. We also estimate asymmetric adjustments under the momentum threshold autoregressive (M-TAR) specification in a TVECM, and the results show that adjustments to eliminate disequilibrium happen faster when oil price spread increases than when it decreases. The long-run and short-run Granger causality tests support the notion that China has influence on the international oil markets. The results imply that China should open up its domestic and imported oil markets, and also establish a well-functioning crude oil futures market, as they are essential for arbitrage and hedging strategies.     

Stock price synchronicity to oil shocks across quantiles: Evidence from Chinese oil firms

This paper investigates behaviour of stock price synchronicity to oil shocks across quantiles for Chinese oil firms. The spillover effects of the oil market on a firm are segregated into firm-specific and market-wide information. First, our results report a higher level of synchronicity by dynamic conditional correlations than by R-square since the former better captures dynamic linear dependence. Second, we find strong evidence of size effect. In particular, stock price synchronicity is generally higher in large-cap firms than in small-cap ones. Oil shocks affect synchronicity in the upper quantiles differently based on firm size. Third, we also find that synchronicity responds to oil shocks significantly in extreme low quantiles, implying that shocks in the oil market are transmitted to Chinese oil firms via firm-specific information. Finally, we determine that oil shocks have little or no immediate impact on stock price synchronicity; instead, cumulative lagged effect is evident. This evidence highlights the lagging effect of spillover of oil shocks on Chinese oil firms.     

WELFARE COST OF AN OIL IMPORT FEE

This paper examines the impacts on the US. oil market of a $5-per-barrel tariff on imported crude oil. The analysis shows that the United States currently is a price taker in the world oil market. This means that "optimal tariff" arguments for an oil import fee have no validity. The author also argues that any economic losses that oil supply disruptions generate are better addressed with alternative policy tools. To forecast the effects of the tariff on US. production, the author uses a domestic oil supply model that she developed elsewhere. She calculates the resulting gains in producer surplus and then combines them with an estimate of consumer surplus losses and government revenues so as to yield an estimate of the tariff's welfare cost. This welfare cost amounts to approximately $17 billion (in present-value terms) over the 1988–1998 period.     

GROWTH,RENEWABLES, AND THE OPTIMAL CARBON TAX

Optimal climate policy is investigated in a Ramsey growth model of the global economy with exhaustible oil reserves, an infinitely elastic supply of renewables, stock‐dependent oil extraction costs, and convex climate damages. Four regimes can occur, depending on the initial social cost of oil being larger or smaller than that of renewables and depending on the initial oil stock being large or small. We also offer some policy simulations for the first and second regime, which illustrate that with a lower discount rate more oil is left in situ and renewables are phased in more quickly. We identify the conditions under which the optimal carbon tax rises or decreases. Subsidizing renewables (without a carbon tax) induces more oil to be left in situ and a quicker phasing in of renewables, but oil is depleted more rapidly initially. The net effect on global warming is ambiguous.     

U.S. OIL DEMAND AND CONSERVATION

Recent history has lent casual support to three popular theories about U.S. oil demand: (i) U.S. oil consumption is very insensitive to changing oil prices, (ii) non-price conservation has reduced U.S. oil demand, and (Hi) U.S. oil consumption falls more when oil prices rise than it rises when oil prices fall. Together, these theories suggest that one could hold oil consumption constant without much economic sacrifice. The authors' econometric evidence does not support these theories. This evidence indicates that U.S. oil consumption is fairly responsive to price changes over the long run, but with a considerable lag. Sharp oil price increases—or an equivalent policy action—would be needed to hold oil consumption constant during the 1990s.

Structural transformation and the oil price

What part of the high oil price can be explained by structural transformation in the developing world? Will continued structural transformation in these countries result in a permanently higher oil price? To address these issues I identify an inverted-U shaped relationship in the data between aggregate oil intensity and the extent of structural transformation: countries in the middle stages of transition spend the highest fraction of their income on oil. I construct and calibrate a multi-sector, multi-country, general equilibrium growth model that accounts for this fact by generating an endogenously falling aggregate elasticity of substitution between oil and non-oil inputs. The model is used to measure and isolate the impact of changing sectoral composition in the developing world on global oil demand and the oil price in the OECD. I find that structural transformation in non-OECD countries accounts for up to 53% of the oil price increase in the OECD between 1970 and 2010. However, the impact of structural transformation is temporary. Continued structural transformation induces falling oil intensity and an easing of the upward pressure on the oil price. Since a standard one-sector growth model misses this non-linearity, to understand the impact of growth on the oil price, it is necessary to take a more disaggregated view than is standard in macroeconomics.     

Oil currencies in the face of oil shocks: what can be learned from time-varying specifications?

While the oil currency property is clearly established from a theoretical viewpoint, its existence is less clear-cut in the empirical literature. We investigate the reasons for this apparent puzzle by studying the time-varying nature of the relationship between real effective exchange rates of five oil exporters and the real price of oil in the aftermath of the oil price shocks of the last two decades. Accordingly, we rely on a time-varying parameter VAR specification, which allows the responses of real exchange rates to different oil price shocks to evolve over time. We find that the reason of the mixed results obtained in the empirical literature is that oil currencies follow different hybrid models in the sense that oil countries’ real exchange rates may be driven by one or several sources of oil price shocks that furthermore can vary over time. In addition to structural changes affecting oil countries, structural changes arising from the oil market itself through the various, time-varying sources of oil price shocks are found to be crucial.     

An asymmetric analysis of the relationship between oil prices and output: The case of Turkey

In this paper we analyze the asymmetric impact of oil price changes on the economic activity in Turkey. In contrast to previous studies on Turkey, the existence of an asymmetric relationship between economic activity and oil prices is investigated by regime-dependent impulse response functions and forecast error variance decompositions based on a multivariate two-regime Threshold VAR (TVAR) model. Our analysis suggests that the relationship between oil prices and macroeconomic activity is nonlinear and exhibits an asymmetric pattern: oil price changes have a significant effect on inflation and output when the change exceeds a certain threshold level. The lower response of macroeconomic variables to oil price shocks in the low oil price change regime also indicates that only the shocks exceeding the optimal threshold level are able to create a contraction in the economic activity.     

Assessing dynamics of crude oil import demand in Korea

Although Korea was the world's seventh largest oil consumer and fourth largest oil importer, relatively little attention has been paid to empirical analyses of the Korean crude oil market. In this paper, we have attempted to expand the scope of previous literature by examining Korea's import demand for crude oil in a dynamic framework of cointegration. The empirical focus is on assessing the short- and long-run relationships among volume of crude oil import, economic growth and price of imported crude oil in Korea. For this purpose, an autoregressive distributed lag (ARDL) approach is applied to quarterly data for 1986–2010. Results show that income level is a more powerful determinant of the long-run behavior of Korea's crude oil imports than crude oil price. In the short-run, on the other hand, oil price is found to play a more important role in determining crude oil imports than income level.     

Interrelationship between crude oil and the stock markets of major demanders and suppliers in emerging and developed markets

This paper investigates the time-varying relationship between the stock markets of advanced and emerging oil-exporting and oil-importing countries and the international crude oil price indices. The results reveal that the time-varying among the oil-exporting and oil-importing countries responds similarly to aggregate supply- and demand-side effects. Oil-exporting countries have a slightly higher integration with the oil markets, while oil supply shocks have a slightly higher impact on emerging oil-exporting countries. The oil markets exhibit a lower time-varying relationship with the Asia-Pacific oil-importing markets, which indicates those markets may be attractive to investors during periods of turbulence in the oil market.     

THE ECONOMIC COST OF U.S. OIL CONSERVATION

This article examines the costs of U.S. oil conservation by using parameters of five world oil models from a recent Energy Modeling Forum study. Variation in the estimated cost of oil conservation across the models suggests that achieving oil conservation through flexible policies that adjust to market conditions would better serve economic efficiency than would setting government-mandated levels of oil consumption. Additionally, net world oil conservation is likely to be somewhat less than gross U.S. conservation. U.S. oil conservation lowers the world oil price and stimulates non-U.S. oil consumption. Including the gains in non-U.S. oil consumption raises the estimated costs of achieving a given conservation level .
