The usage of public procurement to accomplish economic growth and development is extensive, but through evidence about its operations are often imprecise and challenging to discover. This study in effect is to look at the impact and linkage between sustainable procurement and economic growth in Ghana from 1975-2015. The article considers the Solow-Swan growth model and came out with the findings and a result that is consistent with most studies. It was realized that there is a positive and strong relationship as well as the significant impact between sustainable procurement and economic growth. Also, it was recorded that trade openness can be a catalyst for economic growth and development as the results proved there is a significant impact. A Johansen cointegration was employed to determine the long run relationship between economic growth and sustainable procurement and it was found out that there exists a long run relationship. Vector Error Correction Model was employed to study the long run and short run impact of sustainable procurement on economic growth. The study also came out that recently, procurement is employed as a tool to promote economic growth as well as attain sustainable development goals. The study contains some reflections on the connections between procurement and economy, society and environment.

This paper aims to look into the role of institutional quality in regulating energy and growth affiliation. The countries of Sub-Saharan Africa (SSA) are studied from 1990 to 2019. CSD and SH tests were used to verify cross-sectional dependency and slope homogeneity properties. CIPS and CADF were used to investigate stationarity features. The Westerlund bootstrap cointegration test was used to analyze the long-tenure equilibrium affiliation among the variables and confirm cointegration in the extended period. To examine the long-short term performance between the variables, the CS-ARDL approach is used. To analyze the flow of causation, the study used the DH causality process. The findings reveal that energy has a negative and significant impact on growth. In both terms, industrialization and population have a negative and positive impact on growth, respectively. The DH heterogenous causality study reveals the mixed effect, i.e. one-way causal associations between growth and institutional quality, two-way causal associations between energy and population, and no causation with industrialization. Furthermore, institutional quality as a moderating variable harms growth. To achieve long-period growth, states should expand investment in renewable energy sectors, create well-resourced institutions, and plan for renewable energy development, according to this empirical research.
