DEA Analysis of National Oil Companies

Keven Braulio de Jesus Roque Ngeti,Blessed Shinga Mafukidze
National Oil Companies (NOCs) have significant control over the world’s energy resources, holding about 80% of oil reserves and 70% of oil production, with similar figures for natural gas, both the economies of their home nations and the larger global energy market depend on these businesses. However, they perform in a wide range of ways, and a number of factors, such as labor costs, environmental regulations, corporate size, and financial stability, affect how efficient they are.

Granularity: Macroeconomics and Beyond

Sergio Da Silva
Granularity, a macroeconomics concept, explains how small economic shocks can cause significant fluctuations in the broader economy. The granularity hypothesis posits that large firms’ shocks disproportionately impact the economy, countering the idea that these shocks are balanced out at the macro level by the law of large numbers. Granularity, indicating the presence of both few large and many small firms, implies that firm size distribution adheres to a power law, thereby linking granularity a...

Rural Economy Transformation and Education Policy in Sub-Saharan African

Helena Merveille Opombo,Fatimata Diawara
Rural transformation is integrally linked with the wider processes of structural transformation taking place within a given country. Despite the recent upswing in growth within sub-Saharan Africa, economies are still narrowly based on the production and export of unprocessed agricultural products, renewable natural resources, minerals and crude oil. Even with optimistic scenarios on the growth of the manufacturing and services sectors, in formal job creation and agglom-eration effects, it will t...

Regression Modelling of Electricity Distribution Statistics and Stock Exchange Market Capitalisation in a Developing Country: Evidence from Botswana (2012-2021)

Tapiwa Gande
The stock exchange and its performance are important indicators of the economic health of an economy. Electricity generation capacity supports industrialisation. National electricity distribution on the other hand, however, even when mediated with electricity imports to augment a low generation capacity, can complicate both manufacturing and non-manufacturing companies’ desire to operate in an economy which is attempting to industrialise. This is compounded if generation is not matched to consum...

Impact of Foreign Aid on Economic Development and Poverty Alleviation in Sierra Leone

Abu Kai Kamara, Prince Lahai Momoh, Philip Koroma
In capital-scarce low-income economies, the lack of attractiveness to private foreign investment implies that the only readily available source of external financing for economic development must come from foreign aid which normally comes with an altruistic motive. However, despite, the long history of aid-giving to low-income countries and especially in West Africa, evidence of donor aid effectiveness and assistance is debatable, particularly with the dominance of cross-country studies in such ...
