This study aims to investigate the effects of digital overload on job autonomy and job satisfaction among civil servants in the Nigerian public sector using the job demand–resources model.

A questionnaire survey was conducted among mid-career and senior-level officers in five federal ministries in Nigeria. The collected data were analyzed by using structural equation modeling partial least squares to test the research hypotheses and necessary condition analysis to assess the necessary conditions for high satisfaction among civil servants.

The study reveals that the use of information and communication technology (ICT) has a significant positive impact on digital overload. Furthermore, digital overload has a significant negative effect on job autonomy and adversely affects job satisfaction. Additionally, job autonomy partially mediates the relationship between digital overload and job satisfaction. Job autonomy and ICT use were found to be necessary conditions for high satisfaction.

The study acknowledges certain limitations, such as the focus on civil servants in federal ministries in Nigeria and the reliance on self-reported data.

The findings of this study have practical implications for policymakers in the Nigerian civil service. They highlight the importance of reducing digital overload and promoting job autonomy to enhance job satisfaction, as well as to improve the overall performance and efficiency of the public sector.

This study contributes to the existing literature by providing insights into the detrimental effects of digital overload on civil servants’ job autonomy and satisfaction in the Nigerian public sector. It explores a relatively unexplored aspect of digitalization and emphasizes the need to address the negative implications of digital overload. Additionally, it examines the necessary conditions for high satisfaction among civil servants.

This study examines the adoption of information and communication technologies (ICT) for e-recruitment and its impacts on public value outcomes.

A survey was conducted with 213 public sector employees in the federal civil service using a questionnaire to test a conceptual model integrating the Technology Acceptance Model, Media Richness Theory and Public Value Theory using PLS-SEM analysis.

Results validate significant positive relationships between ICT adoption, social media use for e-recruitment and public value creation. Internet self-efficacy positively moderates public value outcomes.

While this study makes valuable contributions, avenues remain to further expand generalizability, strengthen validity and incorporate additional institutional factors in the framework.

The study provides insights to guide policies and interventions aimed at improving ICT adoption success and public value gains from e-government investments in developing countries.

The research makes key contributions by operationalizing and empirically assessing the public value impacts of e-government innovations and examining adoption issues in an understudied developing country context.

Motivated by the negative effect of external shocks on the domestic economy, this study explores the role of financial sector development in absorbing the effect of external shocks on macroeconomic volatility in Nigeria.

Autoregressive distributed lag and fully modify ordinary least square are used to examine the moderating effect of financial development in the link between external shocks and macroeconomic volatilities in Nigeria between 1986Q1 and 2019Q4. External shock is proxy using oil price shock, and financial development is proxy by domestic credit to the private sector and market capitalisation. At the same time, macroeconomic volatility is proxy by output and inflation volatilities. Macroeconomic volatilities are generated using generalised autoregressive conditional heteroskedasticity (GARCH 1,1).

The results indicate that domestic credit to the private sector significantly reduces output and inflation volatilities in Nigeria in the short and long run. However, market capitalisation promotes macroeconomic volatility. More specifically, financial development indicators play different roles in curtaining macroeconomic volatilities. The results also reveal that external shocks stimulate macroeconomic volatility in Nigeria in the short and long run. Nevertheless, the effects of external shocks on macroeconomic volatilities are reduced when the role of financial development is incorporated.

This study, therefore, concludes that strong financial sector development serves as a significant shock absorber in reducing the adverse effect of external shock on the domestic economy.

This study contributes to the extant studies by introducing a country-specific analysis into the empirical examination of how financial development can moderate the influence of external shock on macroeconomic volatilities.
