How does oil price uncertainty affect output in the Central and Eastern European economies? – the Bayesian-based approaches

Abstract

Purpose This paper aims to investigate how oil price uncertainty affects real gross domestic product (GDP) and industrial production in eight Central and Eastern European countries (CEEC). Design/methodology/approach In the research process, the authors use the Bayesian method of inference for the two applied methodologies – Markov switching generalized autoregressive conditional heteroscedasticity (GARCH) model and quantile regression. Findings The results clearly indicate that oil price uncertainty has a low effect on output in moderate market conditions in the selected countries. On the other hand, in the phases of contraction and expansion, which are portrayed by the tail quantiles, the authors find negative and positive Bayesian quantile parameters, which are relatively high in magnitude. This implies that in periods of deep economic crises, an increase in the oil price uncertainty reduces output, amplifying in this way recession pressures in the economy. Contrary, when the economy is in expansion, oil price uncertainty has no influence on the output. The probable reason lies in the fact that the negative effect of oil volatility is not strong enough in the expansion phase to overpower all other positive developments which characterize a growing economy. Also, evidence suggests that increased oil uncertainty has a more negative effect on industrial production than on real GDP, whereas industrial share in GDP plays an important role in how strong some CEECs are impacted by oil uncertainty. Originality/value This paper is the first one that investigates the spillover effect from oil uncertainty to output in CEEC.

Oil Volatility Uncertainty: Impact on Fundamental Macroeconomics and the Stock Index

“…Furthermore, crude oil, being a unique commodity with political and financial characteristics, is influenced by non-fundamental factors such as the US dollar exchange rate, financial crisis, geopolitics, global health crisis, and speculation. Therefore, modeling and forecasting volatility in the oil market represent vital and intricate challenges within both financial and commodity markets (Fan et al 2008;Kilian and Vigfusson 2011;Serletis and Elder 2011;Wang and Wu 2012;Güntner 2014;Van Robays 2016;Cantavella-Jordá 2020;Živkov and Ðurašković 2021;Aladwani 2023;Szczygielski and Chipeta 2023;Zhang and Wong 2023).…”

Direct and Indirect Impacts of Oil Price Shocks on Ecuador’s Economic Cycles (2000:01-2020:01)

“…Clements and Krolzig (2002) use the same approach for a three-regime model. Others consider state dependent mean effects of oil price shocks (Mork 1989, Holmes and Wang 2003, Balcilar et al 2017or Živkov and Đurašković 2022. As in Cologni and Manera (2009) we will consider both cases using different MS-VAR models.…”
