Purpose The purpose of this paper is to examine the relationship between government expenditure and economic growth in Botswana over the period 1985‒2016. The study employed the auto-regressive distributed lag (ARDL) bounds testing approach in investigating the nexus. The study makes the argument that the effectiveness of public spending should be assessed not only against the amount of the expenditure but also by the type of the expenditure. The empirical findings showed that aggregate expenditure has a negative short-run and positive long-run effect on economic growth. When expenditure is disaggregated, both forms of expenditures have a positive short-run effect on economic growth, whereas only a long-run positive impact of recurrent expenditure is observed. The study suggests the need to prioritize scarce resources in productive recurrent and development spending that enables increased productivity. Design/methodology/approach This study examined the effectiveness of government spending in Botswana, within an ARDL framework from 1985 to 2016. To achieve this, the analysis is carried out on both an aggregate and disaggregated level. Government spending is divided into recurrent and development expenditures. Findings This study examined the effectiveness of government spending in Botswana, within an ARDL framework from 1985 to 2016. To achieve this, the analysis hinged on both the aggregate and disaggregated levels. The results of the aggregate analysis suggest that total public expenditure has a negative impact on economic growth in the short run; however, its impact becomes positive over the long run. On disaggregating government spending, the results show that both recurrent and development expenditures have a significant positive short-run impact on growth; however, in the long run, the significant positive impact is only observed for recurrent expenditure. Practical implications The results provide evidence of the diverse effects of government expenditure in the country. In the period under investigation, 73 percent of total government expenditure in Botswana was recurrent in nature, whereas 23 percent was related to development. From the results, it can be observed that although the recurrent expenditure has contributed to increased growth and must be encouraged, it is also pertinent for the Botswana Government to endeavor to place more emphasis on productive development expenditure in order to enhance short- and long-term growth. Further, there is a need to strengthen the growth-enhancing structures and to prioritize the scarce economic resources toward productive spending and ensuring continued proper governance over such expenditures. Originality/value The study provides empirical evidence on the effectiveness of government spending in a small open, resource-reliant middle-income SSA economy and argues that the effectiveness of public spending must be assessed not only against the amount of the expenditure but also on the type or composition of the expenditure. The study contributes to the scant empirical literature on Botswana by employing the ARDL approach to cointegration technique in estimating the long- and short-run impact of government expenditure on economic growth between 1985 and 2016.

Economic growth boosted by high domestic savings has been advocated for by numerous economists throughout the years. For a country like Botswana where the savings-GDP ratio is relatively high, it becomes important to determine whether savings is indeed important for the economy. This paper reexamines the savings-growth debate for the Botswana economy by applying the Bounds testing approach to cointegration analysis to establish the relationship between domestic savings and economic growth in Botswana. The results indicate that domestic savings is significantly positively related to growth in Botswana. The study recommends the need for development of financial instruments to encourage domestic savings.

Concerted effort to diversify Botswana economy, in recent years, has seen increased activity of major sectors, which includes higher reliance on electricity. The demand and consumption of electricity within the Botswana economy increased substantially from the 1980’s. However there have been shortfalls in the country’s electricity generation capacity causing increased reliance on imports from neighbouring countries especially South Africa. Given the importance of electricity in Botswana, this study examined the relationship between electricity and economic growth, employing bounds testing approach to co-integration. Results obtained confirmed the importance of electricity for Botswana’s economic growth. The result also passed a battery of diagnostic tests. This study recommends the need for energy policy reforms that will enable increased electricity production capacity.

Growth theories highlight the importance of domestic savings for Economic growth. The savings and growth literature points generally to a positive growth effect of domestic savings. For a country like South Africa, where the level of domestic saving is low, the question of the role of savings in economic growth becomes critical. An understanding of the contribution of the different forms of savings in an economy to its economic growth is important, especially to be able to make the proper policy addresses. This paper applies cointegration analysis within a multivariate framework to establish the effect of household, government and corporate savings on economic growth in South Africa. The result indicates that corporate saving has a significant positive relationship to growth in both the long and short run, while household and government saving have no significant impact on growth. There is need for policies that increase the level of domestic savings and also a need to address government policies that impact on both public and household savings rate.
