Stock Markets, Banks, and Economic Growth: Empirical Evidence from the MENA Region

Over the last four decades, a wide theoretical debate is concerned with the fundamental relationship between financial development and economic growth. Recent studies shed some light on the simultaneous effect of banks and financial system development on growth rather than a separate impact. The empirical study is conducted using an unbalanced panel data from 11 MENA region countries. Econometric issues will be based on estimation of a dynamic panel model with GMM estimators. Thus, peculiarities of MENA region countries will be detected. The empirical results reinforce the idea of no significant relationship between banking and stock market development, and growth. The association between bank development and economic growth is even negative after controlling for stock market development. This lack of relationship must be linked to underdeveloped financial systems in the MENA region that hamper economic growth. Then, more needs to be done to reinforce the institutional environment and improve the functioning of the banking sector in the MENA region. Based on these results, other regions at the same stage of financial development such as Africa, Eastern Europe or Latin America should improve the functioning of their financial system in order to prevent their economies from the negative impact of a shaky financial market.

On the Determinants and Dynamics of Dividend Policy

The authors study the dividend policy of 48 firms listed on the Tunisian Stock Exchange during the period 1996–2002. The study tests whether or not managers of Tunisian listed firms smooth their dividends. Moreover, the study outlines the main determinants that may drive the dividend policy of Tunisian quoted firms. To answer the first question, we use Lintners model in a dynamic setting. The results clearly demonstrate that Tunisian firms rely on both current earnings and past dividends to fix their dividend payment. However, the study shows that dividends tend to be more sensitive to current earnings than prior dividends. To find out the determinants of dividend policy, dynamic panel regressions have been performed. First, profitable firms with more stable earnings can afford larger free cash flows and thus pay larger dividends. Furthermore, they distribute larger dividends whenever they are growing fast. However, neither the ownership concentration nor the financial leverage seems to have any impact on dividend policy in Tunisia. Also, the liquidity of stock market and size negatively impacts the dividend payment. The results are somewhat robust to different specifications.

The Impact of Capital and Foreign Exchange Flows on the Competitiveness of Developing Countries

Attracting capital and foreign exchange flows is crucial for developing countries. Yet, these flows could lead to real exchange rate appreciation and may thus have detrimental effects on competitiveness, jeopardizing exports and growth. This paper investigates this dilemma by comparing the impact of six types of capital and foreign exchange flows on real exchange rate behavior in a sample of 57 developing countries covering Africa, Europe, Asia, Latin America, and the Middle East. The results reveal that portfolio investments, foreign borrowing, aid, and income lead to real exchange rate appreciation, while remittances have disparate effects across regions. Foreign direct investments have no effect on the real exchange rate, contributing to resolve the above dilemma.

Can Islamic Banking Increase Financial Inclusion

Financial inclusion has become an increasingly important concern for a vast number of countries worldwide. At the same time, a fast-growing amount of literature has emerged to examine its measurement, determinants and impacts. Governments have made the promotion of it a priority. For example, the World Bank’s 2014 Global Financial Development Report (GFDR), devoted to financial inclusion, reports that more than two-thirds of regulatory and supervisory agencies have been tasked with encouraging financial inclusion, and more than 50 countries have set formal targets. Last year, the World Bank President announced a global target of universal financial access by 2020. Defined as the share of the population who use financial services, financial inclusion has proven to be linked to desirable economic outcomes above and beyond those associated with the more familiar concept of financial depth. In this chapter, we analyse the existing country-level information on both financial inclusion and the penetration or presence of Islamic banking in order to ascertain the extent to which Islamic banking has contributed to financial inclusion. This chapter tests for a possible financial inclusion of Islamic banking relationships across a wide variety of measures. Our findings suggest a weak and tentative evidence of Islamic banking’s positive impact on some types of inclusion. This weakness in the results may be partially related to data issues, including the limited coverage of Islamic banking indicators and of financial inclusion indicators among the Organization for Islamic Cooperation (OIC) countries.

What Drives the Performance of Selected MENA Banks? A Meta-Frontier Analysis

This study examines the effect of financial-sector reform on bank performance in selected Middle Eastern and North African (MENA) countries in the period 1994-2008. We evaluate bank efficiency in Egypt, Jordan, Morocco, Lebanon and Tunisia by means of Data Envelopment Analysis (DEA) and we employ a meta-frontier approach to calculate efficiency scores in a cross-country setting. We then employ a second-stage regression to investigate the impact of institutional, financial, and bank specific variables on bank efficiency. Overall, the analysis shows that, despite similarities in the process of financial reforms undertaken in the five MENA countries, the observed efficiency levels of banks vary substantially across markets, with Morocco consistently outperforming the rest of the region. Differences in technology seem to be crucial in explaining efficiency differences. To foster banking sector performance, policies should be aimed at giving banks incentives to improve their risk management and portfolio management techniques. Improvements in the legal system and in the regulatory and supervisory bodies would also help to reduce inefficiency.

The Determinants of Stock Market Development in the MENA Region

Since few decades, a wide theoretical debate is concerned with the fundamental relationship between financial development and economic growth. An efficient financial system leads to a sustainable economic growth. In this study, we are interested especially with stock markets as a main component of the financial system according to the increasing role of financial markets in economies. So, their evolution plays an important role in economic growth. We shed some light on the macroeconomic determinants which must have an important influence on stock markets development. It is recognized that real or financial variables such as real income, saving rate, credit to private sector, M3, value traded, turnover, etc. could have a significant impact on market capitalization. The empirical study is conducted using an unbalanced panel data from twelve MENA region countries. Econometric issues are based on estimation of some fixed and random effects specifications. With such specifications in mind, peculiarities of MENA region countries are detected as well as differentiations among them. Thus, differences in market capitalization are explained. The empirical expected results must reinforce the idea which suggest the important role of economic development in promoting stock market development. Explaining power of variables such as real income, saving rate, inflation, financial intermediary development and stock market liquidity is confirmed. Banks and stock markets seem to be complements instead of substitutes.

Financial Development, Inequality and Poverty: Some International Evidence

This paper provides evidence on the link between financial development and income distribution. Several dimensions of financial development are considered: financial access, efficiency, stability, and liberalization. Each aspect is represented by two indicators: one related to financial institutions, and the other to financial markets. Using a sample of 143 countries from 1961 to 2011, the paper finds that four of the five dimensions of financial development can significantly reduce income inequality and poverty, except financial liberalization, which tends to exacerbate them. Also, banking sector development tends to provide a more significant impact on changing income distribution than stock market development. Together, these findings are consistent with the view that macroeconomic stability and reforms that strengthen creditor rights, contract enforcement, and financial institution regulation are needed to ensure that financial development and liberalization fully support the reduction of poverty and income equality.

Privatization and Financial Market Development in Emerging Countries: A Comparative Study

This paper examines the impact of privatization on stock market size and liquidity in a multinational sample of 31 emerging markets. We find that the intensity of privatization and the use of privatization offerings (POs) on the stock market contribute to enhance stock market development, but the documented effects vary across geographical regions, owing to the specificities of the divestiture process. We use GMM procedure in order to estimate dynamic panel specifications and find that privatization appears to be the most beneficial in the Asian sub-sample where most favorable conditions were put in place before privatization actually started. In other regions, however, similar positive outcomes are yet to materialize. We derive several policy implications from our results.

Asset Pricing and Cost of Equity in the Tunisian Banking Sector: Panel Data Evidence

In spite of popularity and theoretical simplicity of the one-factor Capital Asset Pricing Model (CAPM) used in the valuation of financial assets, researchers are more concerned with the important extension proposed by Fama and French (1993), that is, the Three-Factor Pricing Model (TFPM). Alongside beta, average stock returns could be explained by some size and book-to-market supplementary effects. With these two complementary models, estimation of the cost of equity is carried out for the Tunisian banking sector. In order to account for inter-individual heterogeneity, estimation of parameters is conducted according to random coefficient specifications within the context of panel data analysis.

Basel Capital Requirements and Credit Crunch in the MENA Region

The 1988 Basel I Accord set the common requirements of bank capital to promote the soundness and stability of the international banking system. The agreement required banks to hold capital in proportion to their perceived credit risks, and this requirement may have caused a “credit crunch,” a significant reduction in the supply of credit. We investigate the direct link between the implementation of the Basel I Accord and lending activities, using a data set spanning annual observations covering 1989–2004 for banks in Egypt, Jordan, Lebanon, Morocco, and Tunisia. The results provide clear support for a significant increase in credit growth following the implementation of capital regulations, in general. Despite higher capital adequacy ratios, banks expanded credit and asset growth. Credit growth appears to be driven by demand fluctuations attributed to real growth, cost of borrowing, and exchange rate risk. Overall, the effects of macroeconomic variables, in contrast to capital adequacy, appear to be more dominant in determining credit growth, regardless of the capital adequacy ratio, and regardless of variation across banks by nationality, ownership, and listing.
