Abstract
Purpose
In less competitive markets, firms with market power are likely to exercise pricing power by setting output prices above their marginal cost, inducing welfare losses from resource misallocation, managerial inefficiency and market instability. In order to address such market imperfections, it is important for regulatory authorities to identify the sources of pricing power and devise policies to address their adverse effects. In this context, the purpose of this paper is to undertake an empirical analysis to identify the determinants of pricing power in the South African non-life insurance market.
Design/methodology/approach
The authors estimate the Lerner competitive index as the proxy for pricing power using annual data on 79 firms from 2007 to 2012. In the second stage, the paper employs panel regression techniques in the ordinary least squares, random effects and generalised method of moment’s estimations to examine the effect of insurer level characteristics on pricing power.
Findings
The authors find the market to be characterised by firms with high pricing power. Domestic-owned insurers are found to exercise high pricing power compared with foreign-owned insurers. The authors also identify size, cost efficiency, product line diversification, market concentration, leverage and reinsurance contracts as the significant predictors of pricing power in the market. Finally, through a quantile regression analysis, the authors find the effect of cost efficiency, business line diversification and reinsurance to be heterogeneous across different quantiles of pricing power.
Practical implications
The findings provide regulatory authorities with useful indicators in addressing anti-competitive behaviour in high pricing power to enhance the stability of the insurance market and improve consumer welfare and economic development.
Originality/value
To the best of the authors’ knowledge, this is first paper to examine the determinants of pricing power and competitive behaviour in an insurance market.

Abstract
Purpose
The degree and impact of competitiveness in the banking sector is of great importance as this has great impact on the financial system and the wider economy. A question of interest here is, does competition in the commercial banking sector boost or hamper economic growth. The purpose of this paper is to test the hypothesis that competitiveness in commercial banking is linked to economic growth.
Design/methodology/approach
The authors use the Boone (2008) indicator to estimate competitiveness of banking markets in ten frontier countries in Africa from 2005 to 2012. This model measures banking competitiveness by assessing the relationship between relative marginal costs and relative market share. Through a panel data model, the authors examine the effect banking sector competitiveness has on economic growth.
Findings
The results of Boone (2008) indicator suggest that, to a greater extent, banks in the countries studied have a competitive banking sector. The results of the panel data estimation support the hypothesis that banking sector competition impacts positively on economic growth.
Practical implications
The paper recommends for more policy geared towards enhancing bank competition. This is because competitive banking system will allocate resources more efficiently to improve economic growth.
Originality/value
To the best of the authors’ knowledge, this is the first study to test the link between bank competition and economic growth in a cross-section of Frontier African countries.

The purpose of this paper is to examine the empirical effect of competition on cost and profit efficiency in the South African non-life insurance market in a three-stage analysis.
Abstract
Purpose
The purpose of this paper is to examine the empirical effect of competition on cost and profit efficiency in the South African non-life insurance market in a three-stage analysis.
Design/methodology/approach
Using annual firm level data on 80 non-life insurance companies from 2007 to 2012, the authors first employ the stochastic frontier analysis (SFA) to estimate cost and profit efficiency scores. In the second stage, the authors measure insurance market competition using the Panzar-Rosse (P-R) H-statistics. In the final stage, the authors estimate a fixed-effects panel regression model which controls for heteroskedasticity to examine the effect of competition on the estimated efficiency scores. Firm size, diversification, age, risk, reinsurance and leverage are employed as control variables.
Findings
From the SFA, the authors find average cost and profit efficiency of 80.08 and 45.71 per cent, respectively. This suggests that non-life insurers have high levels of efficiency in cost and low efficiency in profit. The annual estimates of the P-R H-statistics also suggest that firms in the market earn revenues under conditions of monopolistic competition. The authors find a positive effect of competition on cost and profit efficiency to validate the “quiet-life” hypothesis which posits that competition improves efficiency.
Practical implications
Regulatory policies should be directed towards enhancing competition to improve on the low profit earning potential of firms in the non-life market.
Originality/value
To the best of the authors’ knowledge, this study presents the first application of a non-structural measure of competition to examine the empirical relationship between competition and efficiency in insurance markets.

This paper examines the effect of both de jure and de facto measures of financial integration on bank profitability in five regional economic communities of Africa.
Abstract
Purpose
This paper examines the effect of both de jure and de facto measures of financial integration on bank profitability in five regional economic communities of Africa.
Design/methodology/approach
Using panel data from 405 banks operating in 47 African countries across five regional economic communities over 2007–2014, the study constructs a composite measure of bank profitability. The study then employs the dynamic two-step system GMM estimation technique to test the effect of both de jure and de facto measures of financial integration on bank profitability in Africa and across five sub-regional markets.
Findings
Overall, the results support a positive relationship between financial integration and overall bank profitability in Africa, except for the Arab Maghreb Union and Southern Africa Development Community.
Practical implications
The findings of this study suggest that increased financial integration in Africa directly improves bank’s overall profitability and the variations among the sub-regional markets inform tailored policy initiatives.
Originality/value
To the best of the authors' knowledge, this is the first study on Africa to employ a composite measure of bank profitability to assess its determinants. It is also the first to include both de facto and de jure financial integration measures in a single study. This is also the first largest comparative study on bank profitability in Africa.

The purpose of this paper is to investigate the stability of demand for money in the proposed Southern African Monetary Union (SAMU).
Abstract
Purpose
The purpose of this paper is to investigate the stability of demand for money in the proposed Southern African Monetary Union (SAMU).
Design/methodology/approach
The study uses annual data for the period 1981 to 2015 from ten countries making-up the Southern African Development Community. A standard function of demand for money is designed and estimated using a bounds testing approach to co-integration and error-correction modeling.
Findings
The findings show divergence across countries in the stability of money. This divergence is articulated in terms of differences in cointegration, CUSUM (cumulative sum) and CUSUMSQ (CUSUM squared) tests, short run and long-term determinants and error correction in event of a shock. Policy implications are discussed in the light of the convergence needed for the feasibility of the proposed SAMU.
Originality/value
This study extends the debate in scholarly and policy circles on the feasibility of proposed African monetary unions.

The purpose of this paper is to examine how linkages between information and communication technology (ICT) and remittances affect the doing of business.
Abstract
Purpose
The purpose of this paper is to examine how linkages between information and communication technology (ICT) and remittances affect the doing of business.
Design/methodology/approach
The focus is on a panel of 49 Sub-Saharan African (SSA) countries for the period 2000–2012. The empirical evidence is based on the generalized method of moments.
Findings
While the authors establish some appealing results in terms of net negative effects on constraints to the doing of business (i.e. time to start a business and time to pay taxes), some positive net effects are also apparent (i.e. number of start-up procedures, time to build a warehouse and time to register a property). The authors also establish ICT penetration thresholds at which the unconditional effect of remittances can be changed from positive to negative, notably: for the number of start-up procedures, an internet level of 9.00 penetration per 100 people is required, while for the time to build a warehouse, a mobile phone penetration level of 32.33 penetration per 100 people is essential. Practical and theoretical implications are discussed.
Originality/value
To the best of the authors’ knowledge, this is the first study to assess linkages between ICT, remittances and doing business in SSA.

Abstract
Purpose
The purpose of this study is to examine the determinants of capital structure decisions of small and medium enterprises (SMEs) in Ghana. The issue is very relevant considering that SMEs have been noted as important contributors to the growth of the Ghanaian economy.
Design/methodology/approach
Regression model is used to estimate the relationship between the firm level characteristics and capital structure measured by long‐term debt and short‐term debt ratios.
Findings
The results of the study suggest that variables such as firm's age, size, asset structure, profitability, and growth affect the capital structure of Ghanaian SMEs. Short‐term debt is found to represent an important financing source for SMEs in Ghana.
Originality/value
The findings of this study have important implications for policy makers and entrepreneurs of SMEs in Ghana.

Abstract
Purpose
Asymmetric information impedes the efficiency of financial intermediation by widening the gap between lending and deposit rates. The cost of information gathering is high and often translates into high borrowing costs. Consequently, high borrowing costs may make it hard for borrowers to repay loans and increase the volume of non-performing loans – a recipe for financial instability. This study first compares the application of the simple GARCH (1,1) and BGARCH (1,1,1) models in the estimation of macroeconomic volatility and finds that the latter is more suitable for this purpose. Moreover, the choice of BGARCH (1,1,1) over the simple GARCH (1,1) implies different outcomes for Granger causality tests. This finding implies that the BGARCH (1,1,1) model minimises loss of important information when estimating macroeconomic volatility in developing countries. Second, the study uses bootstrap panel Granger causality to test the hypothesis that there is a causal relationship between financial instability and the financial intermediation spread in Southern African Customs Union (SACU). The findings support this hypothesis and underscore the importance of implementing sound macroeconomic policies for high and stable growth as well as effective monetary policy to attain and maintain low and stable prices in order to narrow the financial intermediation spread in SACU. The paper aims to discuss these issues.

Abstract
Purpose
The fundamental objective of this study is to contribute to the debate by empirically examining the determinants of board size and its composition from a small and developing country perspective.
Design/methodology/approach
The paper uses a quantitative approach based on secondary data from firms listed on the Ghana Stock Exchange. Panel data multiple regressions within both fixed and random effects techniques estimations were carried out.
Findings
Board size and its composition are a function of firm and industrial characteristics. Specific findings are that, while firm level risk has a positive relationship with board size, CEO tenure has a negative correlation with board size; and that firms with larger institutional shareholding employ less outside directors
Research limitations/implications
A study of this nature requires a large sample base. It is therefore obvious that sample size was the main limitation of the study. Though, this limitation does not compromise on the validity of our findings, study findings and its general interpretation should be done with some degree of caution.
Originality/value
Since, most of the studies in this area have been largely theoretical and have concentrated in developed countries, this paper makes an important contribution by looking at the issue empirically from a small and developing country perspective.

Abstract
Purpose
The purpose of this paper is to undertake an econometric investigation of the determinants of the nominal South African rand/US dollar exchange rate before and after the country's financial liberalisation in March 1995.
Design/methodology/approach
Regression models are used to examine the changing relationships between the nominal rand/dollar exchange rate and the determinants of capital flows, fundamentals, and country‐specific factors over the long‐run of 1988 to 2007, as well as over the sub‐sample periods of 1988 to 1995, and 1995 to 2007.
Findings
The results show that the factors that are associated with the rand/dollar exchange rate are different before and after the country's financial liberalisation. Prior to 1995, bond and equity purchases by non‐residents, the long‐term interest rate differential, political risk, and the Dollar price of gold were highly significant. However, post‐1995, only the net purchases of shares on the Johannesburg stock exchange (JSE) by non‐residents and the long‐term interest rate differential are significant.
Originality/value
The results suggest that the Rand has changed from being a “commodity currency” in the years before 1995 to being an “equity currency” after 1995.
