The oil and gas sector is the mainstay of the Nigerian economy, accounting for over 95% of its revenue. The study therefore examines the business case for the adoption of Integrated Reporting in the sector. Secondary data<br />were sourced from the annual reports and stand-alone sustainability reports of the six multinational companies operating in the Nigerian oil and gas sector. The results found that efforts to address environmental, social and governance reporting (ESG) were adhoc, short term and unrelated to the core activities of the corporations and as such were not integrated into their business strategies and model. Information on ESG was also duplicated over many medium in a haphazard and distorted form. The study therefore concluded that the introduction of integrated reporting will streamline performance reporting that is in line with international best practice in the sector.

Purpose This study aims to examine the mediating role of audit seasonality on the association between audit fees and audit quality in Nigerian deposit money banks. Design/methodology/approach The sample comprises 14 banks with annual financial statements between 2008 and 2020. The modified Baron and Kenny’s (1986) causal mediation model by Iacobucci et al. (2007) through the use of bootstrapped partial least square structural equation modelling and Sobel’s (1986) z-test is adopted to achieve this study’s objective. Findings The results of the causal mediation analysis show evidence of a fully mediating role of c between audit fees and audit quality in the Nigerian banking industry. Research limitations/implications This study extends the body of knowledge by demonstrating how audit fees influence audit quality through audit seasonality as a mediator in line with the job demands-and resources and conservation of resources theories. Regulatory authorities should be wary of policies that will further increase the workload of already burdened personnel of audit firms as the uniform fiscal year-end of 31 December introduced in the Nigerian banking system has unintended consequences on audit fees and audit quality. Originality/value To the best of the author’s knowledge, this is one of the first studies to provide evidence on the indirect association between audit fees and audit quality.

This study aims to analyze digital marketing adoption among micro and small enterprises (MSEs) operating in Lagos State, Nigeria. This state was chosen because it was the worst hit by the COVID-19 pandemic regarding the reported number of infections and it has a large concentration of MSEs. There is no doubt that the COVID-19 pandemic brought changes to how businesses operate. It succeeded in pushing business owners into adopting new business strategies, all in the bid to adapt to the reality of the pandemic and the associated changes. The cross-sectional survey design was adopted; data were collected through an online survey of 240 MSEs operating in Lagos State. The results show no substantial increase in digital marketing adoption during the pandemic relative to the pre-pandemic era. The findings, however, reveal that digital marketing use differed significantly according to sector and size before and during the pandemic. No changes were found in digital marketing adoption in the information technology and finance sectors, while a decline in digital marketing adoption was reported in the hospitality sector. On the other hand, there was a rise in the use of digital marketing during the pandemic in the agriculture and manufacturing sectors. These findings provide an empirical managerial perspective establishing the link between reality and theoretical business underpinnings.

Economic theory posits that competition drives efficiency; the extent to which this is true in an oligopolistic audit market poses an empirical challenge. Furthermore, studies have postulated that both traditional and modern industrial organization theories are relevant for analyzing market competition. Therefore, this study investigated the effects of static and dynamic audit market competition on audit efficiency in the Nigerian banking industry. Secondary data were obtained from the audited annual financial statements of 12 banks from 2006 to 2020. The study adopted a 2-stage regression model; in the first stage, the audit efficiency scores were derived from an output-based, variable-return-to-scale version of data envelopment analysis (DEA) comprising audit report lag and audit fees as audit input variables and audit quality as the audit output variable. The efficiency scores were regressed on audit market competition and some control variables in the second stage via the bootstrapped truncated regression technique to analyze the effect of competition on efficiency in the audit market. The results showed a positive association between static competition and audit efficiency (50.57, p = 0.014). Because high concentration implied low competition, this finding implied that efficiency was impaired because of a lack of significant competition. The results also showed a positive and significant association between dynamic competition and efficiency, which implied that dynamic competition enhanced efficiency (0.21, p = 0.000) in the audit market. The study concluded that static competition impairs efficiency, while dynamic competition ensures efficiency in the Nigerian banking industry.
