The impact of world oil price shocks on macroeconomic variables in Vietnam: the transmission through domestic oil price

This study examines the impact of world oil price shocks on macroeconomic variables in Vietnam with a focus on the transmission channel of domestic oil prices. The Structural Vector Autoregression model with two blocks of real economy variables and monetary variables is employed. The world oil price follows an autoregressive process to reflect the exogenous nature of world oil price shocks to the domestic economy. The retail domestic oil price is determined simultaneously by only the world oil price due to the government's control of the domestic oil market. Using monthly data in the period between 2009 and 2021, the study indicates that a positive shock to world oil prices will increase the domestic oil prices significantly, industrial production (slightly and only statistically significant in the third month after), and inflation (significantly in 8 months). Besides, the domestic oil price is not the only transmission channel of world oil price shocks to the economy. This result implies forecasting, assessing, and controlling the impact of the world oil price shock on the economy should focus on both domestic oil prices and other indirect channels.     

Global food prices and monetary policy in an emerging market economy: The case of India

This paper investigates a perception in the political debates as to what extent poor countries are affected by price movements in the global commodity markets. To test this perception, we use the case of India to establish in a standard SVAR model that global food prices influence aggregate prices and food prices in India. To further analyze these empirical results, we specify a small open economy New-Keynesian model including oil and food prices and estimate it using observed data over the period 1996Q2 to 2013Q2 by applying Bayesian estimation techniques. The results suggest that a big part of the variation in inflation in India is due to cost-push shocks and, mainly during the years 2008 and 2010, also to global food price shocks, after having controlled for exogenous rainfall shocks. We conclude that the inflationary supply shocks (cost-push, oil price, domestic food price and global food price shocks) are important contributors to inflation in India. Since the monetary authority responds to these supply shocks with a higher interest rate which tends to slow growth, this raises concerns about how such output losses can be prevented by reducing exposure to commodity price shocks.     

The Impact of Energy Prices on Growth and Welfare in a Developing Open Economy

This paper analyzes the impact of an increase in the price of energy (oil) on the growth and welfare of a small developing economy. We consider the extent to which the impacts of energy price shocks depend upon the economy’s internal production structure and its access to the world financial market. We find that the effect on the long-run growth rate depends heavily on the former and is independent of the latter. The effect of accessibility to the world financial market on long-run welfare depends heavily on the elasticity of substitution in production. We supplement the formal analysis with numerical simulations, thereby enabling us to characterize the short-run dynamics. Overall, the simulations can replicate much of the empirical evidence used to characterize the effects of the recent oil price increases on the economy. They also highlight the sensitivity of the effect of the energy price to the elasticity of substitution.     

Oil shocks and endogenous markups: results from an estimated euro area DSGE model

This paper estimates a linearised DSGE model for the euro area. The model is New Keynesian and allows for a role for oil usage and endogenous price markups. The importance of shocks to monetary policy and oil prices is estimated to have declined in the post-1990 period, in line with the higher predictability of policy and the fall in the persistence and—to a lesser extent—variability of oil disturbances. Counterfactual exercises show that oil efficiency gains would alleviate the inflationary and contractionary consequences of oil shocks, while higher wage flexibility would help ease the impact on real output at the expense of larger inflationary pressures. While we report evidence of “countercyclical” price markups, the rise in markups induced by an oil disturbance is not found to considerably amplify the inflationary and contractionary effects of the shock. The paper discusses the policy implications of our empirical results for the euro area economy.

The asymmetric effects of oil price changes on China’s exports: New evidence from a nonlinear autoregressive distributed lag model

China’s dependence on oil imports has greatly increased in recent years. Due to the rapid expansion of global trade, exporting plays an important role in the Chinese economy. This paper uses monthly data from January 2005 to April 2021 to examine the short- and long-term effects of oil price increases and decreases on China’s exports. Our empirical analyses are based on the nonlinear autoregressive distributed lag (NARDL) model, which can effectively capture asymmetric relations. The empirical results provide significant evidence of asymmetry, such that oil price increases have significantly larger effects than oil price decreases in the long term. Interestingly, we find that energy-intensive exports and some specific sectors (e.g., crude fertilizers, petroleum products, and organic chemicals) benefit from oil price increases. We also observe recent declines in the coal and coke sector following positive oil price shocks due to restrictions on coal consumption.     

Macroeconomics of Agricultural Trade Liberalization

Abstract

In this article a macroeconomic model is built to examine interactions between the agricultural sector and the industrial sector in an emerging market economy. This article examines how monetary shock and real shocks produce agricultural price fluctuations and change in employment through multiple cross effects. Monetary shocks result in overshooting of primary commodity price while real shock in terms of rise in the production of primary commodity mitigates the volatility of primary price.     

Openness and the Effects of Fiscal and Monetary Policy Shocks on Real Output in Nigeria (1960–2003)*

Abstract: This study investigates the effects of monetary and fiscal policies on the real output growth in a small open economy. It is a country‐specific, time series study that verifies the implication of increasing economic openness on the efficacy of monetary and fiscal policy. A modified GARCH model was used to estimate the anticipated and unanticipated shocks. Two measures of fiscal and monetary shocks were combined with openness and real oil price shocks in a VECM model to assess the effects of anticipated and unanticipated policy shocks on the output equations. The empirical results showed that anticipated and unanticipated fiscal and monetary shocks had no significant positive effects on real output. This suggests that the open macroeconomic version of the policy ineffectiveness proposition was valid for both monetary and fiscal policy shocks in Nigeria. This is in consonance with earlier works in this area. Furthermore, the degree of openness and oil price shocks had a negative implication on the efficacy of macroeconomic policy in Nigeria; also in agreement with the Dutch Disease Syndrome. Finally, the policy implication of this study therefore is that trade liberalization policy should be implemented cautiously. The Nigerian economy is weak to withstand the unwholesome consequences of full economic integration.     

A nonlinear ARDL model of inflation dynamics in the Philippine economy

This study investigated whether global oil price changes, exchange rate, interest rate, and economic output exert symmetric or asymmetric pass-through effects on inflation in the Philippines. A Nonlinear Autoregressive Distributed Lag (NARDL) model was fitted to the observable data using quarterly observations from 1998 to 2019. Knowledge of these relationships is important in monetary policy setting in achieving targeted inflation; the Philippines adopted inflation targeting in 2002. The finding shows that world oil price shocks are still prominent and the most important determinants of inflation variations in the country. There is prima facie evidence on the short-run asymmetry of oil price changes to inflation. Exchange rate pass-through to inflation was very minimal in the short-run, and there is no long-run effect. Evidence that interest rate and demand shocks have a long-run asymmetric effect on inflation was found. These findings imply that monetary policy setting should account for the asymmetric effects of inflation determinants. Study results provide a deeper understanding of how positive and negative changes of inflation determinants affect actual inflation, which aids policymakers in achieving targeted inflation.     

Influence of oil prices on stock market indexes in Russia and Norway

The effects of oil price dynamics on share quotations are discussed in the paper for the 2000–2012 period for two oil exporting countries—Russia and Norway. It has been shown, using a vector autoregressive model, that, in spite of intuitive expectations, oil prices have not been a systematic risk factor for Russian and Norwegian stock market indices. In Norway, share quotations definitely responded to the dynamics of the US dollar exchange rate relative to the world’s main currencies and the S&P 500 stock index, as well as to fluctuations in the global and domestic interest rates, although to a lesser degree. In Russia, share quotations are practically exclusively affected by their own shocks (a factor that is explained by some specific features characterizing Russia’s major public companies).

Inflation in developing Asia: pass‐through from global food and oil price shocks

The world economy experienced a sharp spike in food and oil prices during 2007 and 2008. In light of developing Asia's dependence on imported oil and food, we can expect higher global food and oil prices to result in higher domestic consumer prices in the region. However, the actual impact of the global commodity shocks on consumer price inflation in developing Asia depends on a number of other factors, including government policy measures. The objective of this paper is to examine empirically the extent of the pass‐through of global food and oil prices to domestic consumer prices in nine countries in the region. The main empirical result is that the magnitude of the pass‐through has been limited. Government policy measures, for example, subsidies and price controls, played a role in reducing or delaying the pass‐through of oil and food price increases to domestic prices.     

Energy Price Shocks and Economic Activity in Texas Cities

It is not known how exogenous shocks in oil price impact city economies. This study examines unemployment rates in Texas cities in relation to oil price movements during the period 1995–2008. We find that unemployment in the bigger cities like Austin, Dallas, and Houston, is not related to oil prices in a significant way when compared to unemployment in the smaller border cites, especially in Laredo. Although the Texas economy has become more diversified and less vulnerable to oil price movements in the last two decades, smaller border cities still experience the effect of oil price shocks, possibly through the neighboring economy of Mexico. Our data indicate significant variations in the unemployment rate in Laredo due to movements in oil price. We observe improvements in the unemployment rates in Laredo as oil price increases.     

日本规避石油价格风险的数字化解读

21世纪初油价攀升并未给日本造成像石油危机时期那样的严重冲击,其主要原因是日本在石油的“量”和“质”等方面有了很大变化。“量”分为“减量”和“增量”两个层面。“减量”是指日本通过调整能源消费结构等措施,相应“弱化”和“缓冲”油价上涨风险;“增量”是指日本通过海外能源投资以及加大石油自主开发等措施部分“对冲”和“转嫁”油价上涨风险。“质”是指日本通过诸措施提升石油利用率,从而相应“舒缓”和“稀释”油价上涨风险。     

On the vulnerability of the oil and gas industry to oil price changes

Previous studies of oil-price economic activity relationships are dominated by macro-level examination of price effects. This study examines the effect of shocks in oil price and its volatility on the oil and gas extraction industry using a Vector Auto-Regressive (VAR) approach. The results show that, in the short-run, positive price and volatility shocks lead to significant increases in oil and gas activities. However, in the long-run, the industry behaves much like the rest of the U.S. economy—price and volatility shocks produce small or insignificant effects. An earlier version of this paper was presented at the 22 ^nd Annual North American Conference of the U.S.A. Energy Economics/International Association of Energy Economics Conference, Vancouver, British Columbia. The authors acknowledge the editorial assistance of Versa Stickle.     

石油价格波动对我国经济的影响

石油作为一种重要能源和资源,广泛应用于各行各业,被誉为经济乃至整个社会的"黑色黄金"、"经济血液"。1973年石油期货出现以前,国际石油价格一直在每桶3美元左右。30多年来国际石油价格一路攀升,2006年7月甚至达到了每桶78美元的"天价"。石油价格的剧烈波动改变着世界政治经济格局,尤其对世界经济的影响日益显著。我国作为当今世界经济发展的重要一员,与世界经济的关联程度日益增强。随着我国经济的快速发展,对石油的需求目益增加,石油的对外依存度不断提高,这就不可避免地受到国际石油价格上涨的影响。因此,认真分析国际石油价格上涨对世界经济和中国经济的影响,提出我国具体的应对措施,对我国经济社会发展和国家安全具有深远的意义。     

The Categorization of Small Open Economies and the Response to Foreign Interest Rate Shocks: Based on Financial Integration and Net External Credit

To analyze precisely effects of foreign interest rate hike shocks, this paper categorizes small open economies into four kinds of types based on the net external credit (or debt) level and the financial integration level. The empirical result shows that responses of macroeconomic variables tend to differ substantially depending on the type of a small open economy. These findings imply that we need to consider the net external credit (or debt) level and the financial integration level of a small open economy when we predict the effect of a foreign interest rate hike shock.     

Price‐Setting Behavior of Korean Firms†

This paper investigates a pattern of price revision by firms in Korea and sheds light on the cause of price stickiness by providing reliable statistical estimates for calibration of the parameters of the widely‐used macro‐models. Based on firm‐level survey data and using a probit model, we identify the firm characteristics or market conditions that discourage firms from carrying out state‐dependent price adjustment. We also estimate the factors driving firms to engage in state‐dependent adjustment rather than wait until the next scheduled revision under three different shocks: demand, general cost and exchange rate shocks. We find a few interesting features, as follows. First, price revision by Korean firms tends to be time‐dependent rather than state‐dependent, with a sizable dispersion across sectors and firm sizes. Second, the pattern of price revision in Korea is not significantly different from that in selected advanced economies. Third, the reason why firms favor time‐dependent price adjustments appears to be endogenous, accounted for by a number of market institution variables. Fourth, in response to shocks, Korean firms tend to wait until the next periodically scheduled revision rather than make a state‐dependent price adjustment, unless marginal costs are affected significantly by the shock, and state‐dependent revisions are often significantly delayed when they do occur.     

Reassessing the role of buffer stock money under oil price shocks

This paper uses the structural vector autoregressive approach to assess the significance of buffer stock money under alternative real shocks in the U.S. economy over the 1960–96 period. Buffer stock effects are shown to play a minor role when oil price shocks are explicitly considered.     

Effects of foreign and domestic economic policy uncertainty shocks on South Korea

This paper investigates the effects of foreign and domestic economic policy uncertainty shocks on South Korea via structural VARs. The results show that both foreign and domestic policy uncertainty shocks exert negative and significant impacts on South Korea. Foreign economic policy uncertainty shocks are found to be more dominant than domestic economic policy uncertainty shocks in influencing the Korean output. The results also indicate that economic policy uncertainty that originates from foreign countries is a significant source of disturbance to the Korean economy, but domestic policy uncertainty plays a rather limited role in explaining Korean business fluctuations.
