Seminar paper from the year 2020 in the subject Engineering - Industrial Engineering and Management, Coventry University (Faculty of Engineering, Environment and Computing), course: Oil and Gas Management (MSc), language: English, abstract: The primary objective of this study will be to work out the financial performance of oil marketing companies (OMCs) in Ghana during petroleum price regulation and deregulation regimes. The researcher adopts the event study design and sampling strategy of purposive random sampling techniques in this study. In this study, the researcher seeks to evaluate the financial performance of oil market companies (OMCs) in Ghana during petroleum price regulation and deregulation regimes. The study also found that, after the deregulation of petroleum prices, there was positive growth in the company's gross sales. The positive effect of the company's financial performance can be attributed to the introduction of the petroleum price deregulation in the downstream petroleum industry. This is to say that the deregulation policy was gradually impacting favourably on the financial performance of the company.
