This paper investigates the trend in the monthly real price of oil between 1990 and 2008 with a generalized autoregressive conditional heteroskedasticity (GARCH) model. Trend and volatility are estimated jointly with the maximum likelihood estimation. There is long persistence in the variance of oil price shocks, and a GARCH unit root (GUR) test can potentially yield a significant power gain re...

This paper uses a quantile impulse response approach to investigate the impact of oil price shocks on Chinese stock returns. This process allows us to uncover asymmetric effects of oil price shocks on stock market returns by taking into account the different quantiles of oil price shocks. Our results show that the responses of Chinese stock market returns to oil price shocks differ greatly, dep...

This paper examines the effect of the volatility of oil prices on food price in South Africa using monthly data covering the period 2002:01 to 2014:09. Food price is measured by the South African consumer price index for food while oil price is proxied by the Brent crude oil. The study employs the GARCH-in-mean VAR model, which allows the investigation of the effect of a negative and positive s...

Iran is one of the oil exporting countries, so the oil price plays a remarkable role in the government budget and is a major source of foreign exchange. On the other hand, the reliance of the government budget to oil income as well as its fluctuations is a fact referred to as the most important cause of inflation by many researchers. This paper explores the effect of shocks in the exchange rate...

oil prices may be having a direct and indirect effect through the exchange rate on the price of agricultural commodities. in this paper, the impact of world oil prices and exchange rate shocks on prices of specific agricultural commodities including wheat, corn, soybeans and sunflowers in iran is discussed. for this purpose, vector autoregressive model with monthly data over the period 2010-199...

Oil price shocks are the major source of economic instability in oil exporting developing countries, including Iran. In this paper a Multi Sector Dynamic Stochastic General Equilibrium model, with emphasis on optimization of oil sector as a producing sector is designed. Furthermore, an optimizing import sector is introduced into the model by considering the price rigidity in imported goods as a...

 The oil price shocks are an important source that affect on TOT in both oil exporting and importing countries. Hence, this paper compares the effects of real oil price shock on TOT in both oil importing and exporting countries, using Panel Data technique and during 1980-2010. To the best of our knowledge, we applied the nonlinear approach in order to assess the asymmetric impact of the oil pri...

This paper analyzes the response of international oil producers to demand-induced changes in the real price of oil during 1975–2011. The goal is to disentangle fluctuations in OPEC and non-OPEC production and to derive consistent estimates of the short-run price elasticity of crude oil supply at the country level. I find that oil producers hardly respond to demand shocks within the same month, ...

In practice, central banks have been confronted with a trade-o¤ between stabilising in‡ation and output when dealing with rising oil prices. This contrasts with the result in the standard New Keynesian model that ensuring complete price stability is the optimal thing to do, even when an oil shock leads to large output drops. To reconcile this apparent contradiction, this paper investigates how ...
