Determinants of stock market development: a review of the literature

Purpose - This paper aims to provide a comprehensive review of the literature on the determinants of stock market development. Design/methodology/approach - The paper divides the existing studies into the theoretical and empirical literature. Then, it analyses these studies in turn. Findings - Based on the theoretical literature, the determinants of stock market development can be broadly classified into two groups: macroeconomic factors and institutional factors. The theory and the empirics predict different ways in which macroeconomic factors affect stock market development. The real income and its growth rate foster stock market development, while the banking sector, interest rate and private capital flows can foster or inhibit it. Inflation and exchange rates have adverse effects on stock market development. In terms of the institutional factors, the literature indicates that different legal origins and stock market integration can have a positive or negative impact on stock market development. In addition, factors such as legal protection of investors, corporate governance, financial liberalisation and trade openness contribute positively to the development of the stock market. Research limitations/implications - From the survey, it is imperative that policies which aim at enhancing institutional quality, financial integration, real income growth, macroeconomic stability and capital inflows, among others, will certainly promote stock market development within and across countries. Although the empirical studies have incorporated a large set of variables in their models, the theoretical studies do not contain rich models of stock market development. It is understandable that a theoretical model which contains a large set of the determinants of stock market development may be difficult to solve. However, such a model seems very appealing and will provide a unification of the existing literature. Originality/value - The originality of the paper lies in the fact that it is the first to undertake a survey of the determinants of stock market development in the literature. It is hoped that this paper will spur further theoretical and empirical research on the determinants of stock market development.

The Real Exchange Rate, the Ghanaian Trade Balance, and the J-curve

ABSTRACT Using linear and nonlinear specifications, we studied the effects of real exchange rate changes on the trade balance of Ghana during the period 1986Q1 to 2016Q3. We found no evidence in support of the short- and long-run impact of exchange rate changes on the trade balance in the linear specification. The J-curve is refuted in this case. In contrast, exchange rate changes affected the trade balance in the nonlinear specification. Depreciations improve the trade balance in the long run, but appreciations have no impact. Hence, exchange rate changes have nonlinear effects on the trade balance. This is consistent with the J-curve phenomenon.

The Penn Effect revisited: New evidence from Latin America

In this paper, we examine the role of relative productivity growth in real misalignment of exchange rates in Latin American countries. Specifically, we verify the validity of the Penn Effect for selected countries in this region. Our sample consists of 15 countries for the period 1951 to 2010. We employ both short‐ and long‐panel data techniques, which allow us to experiment with estimators suitable for short and long time dimensions of panel data. The Penn Effect is found to be supported for the entire sample, and for subsamples. Relative productivity growth is dominant in the real exchange rate movement during periods of mild or weak speculative attacks, as compared with periods of severe speculative attacks. To correct for real misalignment of currencies in Latin America under speculative attacks, relative productivity growth must be sizeable.

The real effect of currency misalignment on productivity growth: evidence from middle-income economies

There have been interesting perspectives on the role of real currency misalignment in productivity growth. Whereas some studies warn against the destructive effect of real currency misalignment on productivity growth, others simply encourage it, at least, in the form of undervaluation. This paper documents evidence in support of the latter argument for 100 middle-income countries for the 1994–2010 period, using fixed-effects and generalized method of moments estimation techniques. The paper finds real currency misalignment to enhance productivity growth if it occurs as undervaluation; and to hamper productivity growth if it occurs as overvaluation. The paper also finds the impact of real currency misalignment on productivity growth to be symmetric, implying that the size of the impact is independent of the size of the misalignment. Moreover, the choice of the real misalignment measure may matter.

Assessing the Effects of Housing Market Shocks on Output: The Case of South Africa

This paper assessed the effects of housing market shocks on real output in South Africa over the period 1969Q4 – 2014Q4, by emphasizing the real private consumption channel. The agnostic identification procedure employed in this paper has delivered impulse responses that are overall consistent with the existing literature. The paper appropriately identified housing market shocks as non-monetary housing demand shocks. 20% of the variation in house prices are explained by the housing market shocks. The effects of housing demand shocks on real private consumption are short-lived, explaining why real output responded transitorily to these shocks. Housing demand shocks have managed to explain nearly 13% and 14% variations in real private consumption and real output, respectively, over 20-quarters ahead forecast revision.

Nonlinear effects of exchange rate changes on the South African bilateral trade balance

ABSTRACT In testing for the J-curve, previous studies have shown that the trade balance model is better fitted using cointegration and error correction mechanisms. These mechanisms are able to incorporate the short-term deterioration and the long-term improvement of the trade balance – the definition of the J-curve. However, the drawback of the established cointegration and error correction frameworks is that they assume symmetry in the equilibrium adjustment process. Incidentally, studies which have used the linear frameworks have found little support for the J-curve. Since the adjustment process could be nonlinear, a fresh investigation of the J-curve using nonlinear approaches could provide competing evidence. This paper retested the J-curve by using quarterly data for South Africa and her key trade partners (China, Germany, India, Japan, the UK and the USA) and found the linear specification to support the J-curve phenomenon in only two cases (India and the USA) under relaxed conditions. In contrast, the nonlinear specification supported the J-curve phenomenon in all cases at no cost of serial correlation and functional misspecification. We also found the real exchange rate changes to have significant nonlinear effects on the South African trade balance.

The Determinants of Economic Growth in Ghana: New Empirical Evidence

This article deals with an investigation into the determinants of economic growth in Ghana over the period from 1975 to 2014. In particular, we investigated the impact of physical capital, human capital, labour, government expenditure, inflation, foreign aid, foreign direct investment, financial development, globalization and debt servicing on economic performance within an augmented Solow growth model. It was found that, in the long run, both human capital and foreign aid have a positive influence on output, while labour, financial development and debt servicing have a negative impact on output. It was also found that, in the short run, government expenditure and foreign aid have a positive influence on economic growth, while labour, inflation and financial development have a negative impact on economic growth. These findings hold important policy implications for the country.

Exchange rate uncertainty and domestic investment in Ghana

Abstract The impact of exchange rate uncertainty on domestic investment remains a topical issue in international finance. The existing studies based on macro- or micro-level data have produced mixed findings leaving the issue widely open for further investigation. We revisit this issue at the macro-level by differentiating the short-run impacts of exchange rate uncertainty from long-run impacts. Using annual data for Ghana covering the period 1980–2015, we found that exchange rate uncertainty has differential impacts on domestic investment in the short run. That is, while the current level of uncertainty enhances investment, previous levels of uncertainty dampen investment. In the long run, exchange rate uncertainty has a positive impact on domestic investment. These findings are robust to alternative specifications of our model.
