SUMMARY:

This dissertation is composed of three independent essays on petroleum economics that have the general objective of contributing to the general literature on energy economics through the analysis of some of its main characteristics. The first chapter aims to analyze the effects of the invasion of Ukraine by Russia in February 2022 on the prices of WTI oil futures contracts, causing a significant increase, leaving the US$ 90 range and reaching the US$ 130 mark per barrel in a few days, an increase of more than 40% in contract prices. Such instability directly affected the global supply chain, worsening a scenario that had not been favorable for some time. This essay investigates the upward trend in oil prices, detecting a structural break in the series studied through the Chow, Quandt-Andrews and Bai-Perron tests, all identifying the date of February 27, 2022 as the point of change in the data series analyzed. The second chapter reflects wages perspectives in the oil and gas sector in Brazil. Given the economic importance of this activity and its multiplier effects on the economy. The hypothesis is that, even in the face of significant cyclical and structural changes in the job market in general and in the oil and gas sector in particular, it offers better remuneration on average, in addition to complementary benefits, with opportunities for career advancement and financial stability in general. The data were obtained from IBGE’s Continuous PNAD, and as a result, it appears that the oil and gas sector maintain high levels of wages and income even when compared to other important sectors, in addition to its participants having preserved their purchasing power, even with inflationary losses in the period analyzed.
