In this digital age, students and researchers are less and less dependent on physical libraries. Any university library without internet connectivity is simply cut‐off from the rest of the world. Because they cannot provide quality and timely services to its users, neither can they communicate or share knowledge with others globally. The purpose of this study is to investigate the availability of internet connectivity in university libraries in Nigeria, and to bring to limelight their readiness to render quality services and communicate with the rest of the world.

The study covered the 104 universities in Nigeria made up of federal, state, and private universities. Out of the number, 86 university libraries responded to the survey. E‐mail and telephone interview methods were used to elicit data from the university librarians and senior library personnel.

The study revealed that despite the laudable directives from the National University Commission (NUC), many university libraries in Nigeria are still operating without internet connectivity. They are mostly the state‐owned and private university libraries. This may be why many programs in the universities are either suffering from partial or no accreditation from the NUC Accreditation Team. Many of the university librarians and senior library personnel interviewed mentioned lack of fund, absence of technical staff to maintain the networks, and lack of maintenance culture as some of the factors hindering internet connectivity.

The paper will help decision makers plan for installation of internet facilities in their libraries.

The paper calls for proactive effort by the library administrators to lobby for fund and the technical staff to enable their libraries get connected to the rest of the world.

Researchers have long been interested in testing the validity of Okun’s law due to its macroeconomic policy implications. However, most of the studies have focused on testing the law using aggregate data on unemployment and output. In recent times, attention has been shifted to testing the law at the sectoral level. In light of this, the purpose of this study is to examine the response of unemployment to sectoral outputs in Nigeria using the data that covers a period from 1981-2020.

To test the validity of Okun’s law at the sectoral level, both difference and gap methods of specifying Okun’s law are used. Furthermore, the author also uses a series of estimation methods, which include ordinary least squares (OLS), dynamic OLS (DOLS), fully modified OLS (FMOLS) and canonical cointegration regression (CCR).

The results, based on the difference model, are mixed irrespective of estimation and data filter methods. For the gap model, Okun’s law holds for all sectors irrespective of estimation techniques (especially DOLS, FMOLS and CCR) when the Hodrick–Prescott filter method is used to filter data. However, the author discovers that the coefficients of Okun’s law vary across the sectors as the response of unemployment to services sector output is greater than the rest of the sectors. When the Hamilton filter method is used to filter data, the results appear to be mixed across the sectors. The results are almost ditto when all the sectoral variables are put in one model.

To the best of the author’s knowledge, this is the first study that investigates the validity of sectoral Okun’s law in Nigeria, the leading economy in Africa.
