Regional financial integration and its impact on banking development: Evidence from Southern African Development Community countries

Abstract

The study investigated the impact of regional financial integration on banking sector development with specific focus on the impact of the Southern African Development Community protocols on trade and finance and investment. A total of 14 countries made up the study sample, and the panel cointegration fully modified ordinary least squares model (FMOLS) alongside the generalized method of moments (GMM) were used to estimate the nature of the impact. Study findings showed that regional integration through the protocol on trade had a positive and significant impact on size and efficiency of the banking sector using the FMOLS estimator. GMM estimations for the same variables were largely insignificant. Study findings also pointed to an improvement in global financial integration indicators as a result of the trade protocol, which in turn also contributed to an increase in the level of monetization of regional financial markets. The finance and investment protocol had a positive and significant impact on private sector credit for both estimators and largely insignificant relationship with broad money. The study also observed the complimentary relationship between institutional quality and social capital in the financial development process indicating the importance of policies that strengthen sound legal systems, protect property rights, and enhance the rule of law.

Determinants of Trade Openness in Transitional Economies: Does the Complementarity between Foreign Direct Investment and Human Capital Development Matter?

“…Results of Kao (1999) OPEN 1, OPEN 2 and OPEN 3 stands for trade openness as measured by total trade (% of GDP), total exports of goods and services (% of GDP) and total imports of goods and services (% of GDP) respectively. The panel co-integration results show that a null hypothesis which states that there exists a long run relationship between the variables under study cannot be rejected at 1 percent significance level, in line with Tembo (2018). Similar results were also found by similar empirical research done by Osei et al (2019), Mbogela (2019) and Tahir et al (2018).…”

Macroeconomic Determinants of Energy Consumption in BRICS (Brazil, Russia, India, China, South Africa)

“…Unlike at level, all variables used are integrated of order 1 at first difference. These results paved way for panel co-integration tests to be undertaken, consistent with Tembo (2018).…”

Global diversification, profitability and revenue creation: Evidence from an emerging economy

“…Investors might benefit from opportunities in various economies and locations that may have varying economic cycles or growth prospects by diversifying their holdings geographically (Miah et al, 2023). Furthermore, research has indicated that geographic diversification can provide a more stable portfolio and lower volatility over the long term, both of which can increase risk‐adjusted returns (Tembo & Makina, 2020; Wulansari & Adhariani, 2023). By combining diversification strategies, managers may be able to better manage the complexity and diversity created by each strategy.…”
