We investigate how the dynamic e¤ects of oil supply shocks on the US economy have changed over time. We …rst document a remarkable structural change in the oil market itself, i.e. a considerably steeper, hence, less elastic oil demand curve since the mid-eighties. Accordingly, a typical oil supply shock is currently characterized by a much smaller impact on world oil production and a greater e¤...

A new time series model is proposed to describe observed asymmetries in postwar unemployment data. We assume that recession periods, when unemployment increases rapidly, are caused by unobserved positive shocks. The generating mechanism of these latent shocks is a censored regression model, where linear combinations of lagged explanatory variables lead to positive shocks, while otherwise shocks...

according to the importance of careful review of crude oil market fluctuations on the iranian economy, in this paper a multivariate model of markov switching vector error correction model (have been used). variables such as real gross domestic product in industrial sector, real effective exchange rate, real governmental expenditure, real import, inflation rate and real crude oil price is used t...

The price of a barrel of crude oil doubled within a few months last year. Although prices have been easing lately, for those who paid more than $3 for a gallon of gas, the memory is not likely to fade quickly. But worries about higher gas prices don’t end at the pump. Oil price shocks—sudden and sharp increases in the price of oil and its derivatives like gasoline—are associated in the popular ...

This paper investigates the common movements of commodity sectors in China as well as the economic underpinnings of the comovements. We employ a Bayesian dynamic latent factor model to disentangle the common and idiosyncratic sector-specific factors of the prices of a group of China's commodity sectors: petrochemicals, grains, energy, non-ferrous metals, oils & fats, and softs. The results indi...

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...

This paper studies the impact of oil price shocks on fiscal policy and real GDP in Oman using new unexplored data. We find that an shock explains around 22% 46% government revenue variation, respectively. Decomposing further into petroleum non-petroleum related components, we 26% variation 90% petroleum-GDP. Though respond positively to shocks, expenditure is not directly affected by prices but...

The paper investigates the macroeconomic and financial effects of oil prices shocks in the euro area since its creation in 1999, with a special focus on the recent slump. The analysis is carried out episode by episode, within a time-varying parameter framework, consistent with the view that "not all the oil price shocks are alike", yet without imposing any a priori identification assumption. We...
