The purpose of this study is to determine if the Brazilian electricity sector is differently affected by the characteristics of the content in the regulatory legislation.

For better robustness of the research, the authors analyzed the period from 1995 to 2013, totaling 4,510 observations. To this end, the selection of regulatory legislation was conducted through Markov regime switching. To identify the characteristics of profile and intensity of regulatory content in each legislation, we applied the content analysis technique.

The main findings of this study position this research in the vanguard regarding other research in the area by showing that all regulatory measures whose characteristics denote market profile of strong and medium intensity affect the risk of electric utilities in Brazil. As contribution from this research, it can be hypothesized that for provisional measures/laws events, the profile and intensity of regulatory content are relevant and have different impact on the risk of stocks and, therefore, should be considered in the design and development of public policies.

The paper investigates by means of content analysis, the profile and intensity characteristics of the content present in the regulatory legislation and to present the impact of these characteristics on the risk of the electric energy Sector in Brazil. The research results showed that it is not all regulatory events that impact the stock market. Therefore, regulatory risk estimates must consider the intensity and scope of each legislation, given that legislation with a higher regulatory content that seeks to modify the sector’s operating rules more deeply tends to have a greater impact on the risk of companies that operate in regulated sectors. Therefore, the paper shows originality and evolution for the researchers in the area, with new and significant information.

It is basically known that the oil and gas industry contributes to various forms of pollution through air, acid rain and water, as well as different kinds of illnesses in humans and aquatic animals. Eventually, this adversely contributes to climate change owing to increases in emission levels in various stages of oil and gas operations ranging from extraction, refining, transportation and even consumption. Therefore, the purpose of this paper is to produce a simplistic model for compliance with environmental taxes in the oil and gas industry as an effort to curtail such adversities. This attempt is expected to set a new pace for heated debates towards the production of a robust environmental tax compliance model through further research. Specifically, it has examined the effect of extensive regulation and use of power in ensuring compliance with environmental taxation via enforcement mechanisms.

The study used a quantitative research design through a positivist paradigm. The population of the study was 115 respondents who were identified as tax experts in three different stakeholder groups (regulators, operators and enforcers) in the Nigerian oil and gas industry. Out of this population, 103 served as the final sample of the study. The data collected from these tax experts were analyzed through partial least squares structural equation modelling.

The results revealed that both extensive regulation and the use of power have high likelihoods of enhancing compliance with environmental taxes through enforcement actions by the relevant authorities within the oil and gas industry.

The results implied the need for policymakers to deploy these enforcement mechanisms to enhance compliance with environmental taxes in the oil and gas industry, which will eventually reduce the environmental menace and ensure cleaner production. The paper also has highlighted the need for future researchers to expand this discussion through an elaborative approach either through disaggregating the variables studied here or integrating voluntary compliance mechanics into the model for further understanding of the drivers of environmental tax compliance. It also implied the need to utilize larger sample in other oil producing countries to improve generalization of results.

The work could be the pioneer in proposing and validating the enforced environmental tax compliance model in the oil and gas industry.
