Equity Indices

Despite the increasing attention to ethical investments, the empirical studies on Islamic indices are scarce. Our article aims to contribute to the empirical literature by exploring the efficiency of these indices and their potential for diversification in comparison with the conventional benchmarks. We explore the existence of diversification opportunities by studying whether indices are cointegrated or not. Then, the weak-form efficiency level is analyzed by testing the random walk hypothesis using variance ratio tests. Our sample includes Islamic and mainstream indices of four indices families; among them, two Shariah-compliant indices which have not been studied before in the academic literature Our results show that Islamic indices have the same level of (in)efficiency as conventional ones, the indices of MSCI and FTSE families are the less inefficient. In terms of cointegration analysis, Islamic indices of Dow Jones and S&P have no cointegrating relations with their respective benchmarks, which suggests the existence of long-run diversification opportunities.

The factors required to achieve sustainable economic growth in a country are debated for decades, and empirical research in this regard continues to grow. Given the relevance of the topic and the absence of a comprehensive, systematic literature review, we used bibliometric techniques to examine and document several aspects in the empirical literature related to growth, from 1991 to 2020. Five main results are worth highlighting: (a) the share of empirical articles on economic growth show a clear upward trend; (b) among all the groups of countries considered, the emerging economies (EEs) have received the most scientific attention; (c) the economic growth processes of the Latin American and Caribbean EEs have observed negligible scientific attention; (d) the very long-run studies comprise a residual share among the empirical literature on growth; (e) the extant empirical studies on economic growth have addressed mainly the impact of “macroeconomic conditions.” Our findings suggest there is a need to redirect the empirical growth agenda, so as to encourage more scientific attention devoted to the analysis of key determinants of economic growth in the very long run. There should also be increased scrutiny of the processes of economic growth in Latin American and Caribbean EEs

The issue of whether public investment crowds out or crowds in private investment has received considerable attention in the economic literature. Most of the empirical studies that examined the long run stable association between public and private investment have focused on examining this relationship for the developed countries with very little attention on the developing countries. The empirical results of these studies, however, are highly controversial. The existing empirical studies in this area can be divided into three categories. The studies in the first category including Barro (1974), Kormendi (1983), and Feldstein (1982) have examined the empirical implications of the Ricardian equivalence hypothesis (REH). The empirical results of most of the studies in this category were supportive of the REH. Seater (1993) argues that good empirical studies generally provide evidence in support of the REH; however, some studies refute it owing to the lake of econometric accuracy.

We test the nature of weak form informational efficiency present in the wine market using daily return of LIV-EX 50 index from 1/1/2010 to 12/6/2020. First, we employ a number of statistical tests including variance ratio tests, tests for linear and non-linear dependence and Hurst coefficient. The tests are applied on the full dataset and on four non overlapping sub-samples of equal length. The variance ratio tests provide a mixed regarding informational efficiency. Evidence of non-linear dependence in the return series was found. The Hurst coefficient values confirm the presence of long run persistence in the wine market. Based on the mixed evidence, we test the possibility of adaptive nature of the wine market. We employ the newly proposed Adaptive Index (AI) to quantify the degree of information inefficiency in the wine market at any instance. Our results confirm that wine market is adaptive and periodically shifts between states of efficiency and inefficiency. The wine market is found to be relatively free from the Covid-19 induced shock and the safe haven property of wine is thus confirmed. Finally, impact of various macroeconomic and financial events on wine market efficiency is identified by using AI.

Financial sector activities are part of the main ingredients for the growth of any economy. The financial activities that were most widely practiced are Interest-based conventional financial activities which are prohibited in Islam. Thus, non-interest Islamic financial activities were introduced and it has been accepted and practiced all around the globe. Therefore, this study surveyed, explored and analysed using library review method, the empirical studies conducted on Islamic finance and the economic growth nexus. The study revealed that the majority of the findings of the empirical studies are in support of a positive and significant contribution of Islamic finance to the growth of the real economy in short run and long run, few of the findings indicate an insignificant contribution. The causal relationship between Islamic finance and growth is mostly bi-directional as reported in many of the studies, but supply leading hypothesis also emerged in some of the few studies. It was concluded that Islamic finance is immensely contributing to the growth of the real economy.

Abstract We study the informational efficiency of the Saudi stock market (SSM), while accounting for corporate governance change, based on single, multiple, and variance ratio-based WALD tests and runs test. The main findings indicate that when the whole period is considered, the random walk hypothesis is rejected, but when divided into two sub-periods separated by the pre-corporate governance and the period marked by corporate governance change, the analysis demonstrates sub-period improvement in weak-form efficiency for the examined series. Robustness of results is verified by analysis using sector indices, which point to market efficiency. Interestingly, Hurst Exponent estimates evidence long-range dependence which suggests the predictability of stock prices and the prospect of speculative opportunities.

The study investigates the stock market efficiency of selected OPEC member countries within the context of random walk hypothesis and volatility approaches using monthly data on stock market indices from January, 2005 to April, 2016. Parametric (variance ratio: homoskedastic and heteroskedastic martingale), nonparametric (the Wright ranks and scores) tests and ARCH type estimation are performed. Results of both parametric and nonparametric tests indicate that only Qatar's stock market is weak-form efficient. The volatility results suggest that monthly stock returns of OPEC countries are volatile, with Qatar being most volatile and shocks to volatility of stock returns are asymmetric. The implications of this are that: first, investors should be conscious of these shocks when making risk-return decision of their portfolios; second, the results provide useful information to regulators to enable them develop safeguard mechanisms to shield the market from possible asymmetric information emanating from the participants.

Weak Form Efficiency

This chapter reviews empirical studies on weak form of efficiency with the aim of establishing whether the African market is inefficient or adaptive. The reviewed studies are categorised based on their methodological approaches to compare the power of linear and non-linear models in testing for weak-form efficiency. The studies on calendar anomalies, an indication of weak-form inefficiency, are reviewed to assess whether these anomalies are adaptive as portrayed by the relatively recent theory of adaptive market hypothesis (AMH). The scope of reviewed studies is also extended to developed and emerging markets to gain a broad comparison of the findings. This review revealed that non-linear dependence has been revealed in stock returns suggesting that non-linear models are best fit to test for the stock market efficiency. Reviewed studies produced contradictory findings with some supporting and others rejecting weak-form efficiency. Thus, most studies support the AMH, which suggests that market efficiencies and anomalies are time changing. This chapter concludes that most of the existing studies on AMH have been carried out in markets other than Africa, and hence, further empirical studies on the evolving and changing nature of efficiency in African stock markets are recommended.

Purpose During recent years, the nexus between unemployment and entrepreneurship has been examined in depth in developed and industrialised economies but rarely in developing economies. The purpose of this paper is to investigate such a relation in the case of 30 Iranian provinces from 2005Q2 to 2017Q4. Using both the autoregressive distributed lag (ARDL) bounds testing and vector error correction method (VECM) Granger causality approaches, the findings show that a unidirectional short-run causal relationship from entrepreneurship to unemployment and vice versa was observed in 13 and 10 per cent of provinces, respectively. The authors also find evidence for unidirectional long-run causality in 77 per cent of provinces from unemployment to entrepreneurship, as well as 10 per cent of provinces from entrepreneurship to unemployment. Finally, the results confirm that in long-run, the “prosperity-pull” effects are considerably stronger than the “recession-push” effects in Iranian provinces. Design/methodology/approach The main target of this paper is to investigate the unemployment-entrepreneurship in the case of 30 Iranian provinces from 2005Q2 to 2017Q4 by using ARDL bounds testing and VECM Granger causality approaches. Findings The results confirm that in long-run, the “prosperity-pull” effects are considerably stronger than the “recession-push” effects in Iranian provinces. This finding reveals that the unemployment rate can be regarded as a critical instrument for hindering entrepreneurial activity by increasing the risk of business bankruptcy and pulling entrepreneurs out of self-employment. All these results must be taken into account in the construction of useful economic policies for the Iranian labour market. Originality/value The economic literature reveals that most empirical studies of the nexus between unemployment and entrepreneurship examined developed and industrialised economies and the analysis of such a relation for developing countries has not been considered by researchers. Thus, to fill this gap, this paper extends the current empirical literature by presenting new empirical evidence for the case of Iran, which has a developing economy.

This study examines the long-run relationship between exchange rates and relative prices. We use a long memory techniques that allow for persistence of chock relationships across real exchange rate to examine the existence of weak-form and strong-form Purchasing Power Parity (PPP) between the Tunisian and five partner countries of Tunisia, namely, (Germany, the United States, France, Italy, the UK, Morocco and Libya. The empirical results obtained through the R/S, Modified R/S, GPH and ELW tests; make us consider the PPP as an event in the long run if significant short-term deviations from the PPP cannot exist. Therefore, the analysis of the fractional cointegration makes the deviations, regarding equilibrium, follow a slightly integrated process and therefore capture a much wider group of research parity or mean-reverting behavior.

The Relationship

This article provides a detailed survey of existing theoretical and empirical literature on the impact of public debt on economic growth in both developing and developed economies. The aim of the article is to add to the existing debate on the relationship between public debt and economic growth in world economies. The survey finds diverse and, in some cases, inconsistent evidence on the relative impact of public debt on economic growth. Although the majority of the surveyed literature supports the negative effect of public debt on economic growth, several other studies have found a long-run positive impact of public debt on economic growth through the fiscal multiplier effect. The article also found that a few other studies support the Ricardian Equivalence Hypothesis (REH), which states that the relationship between public debt and economic growth is nonexistent. On balance, the article also found that there is a growing body of empirical evidence, which supports the presence of threshold effects in the relationship between public debt and economic growth. Overall, it concludes that theoretical models and empirical studies yield inconclusive results depending on a set of heterogeneous factors, including the level of development of the sampled countries, data coverage, methodology used, and the researchers’ choice of control variables, among other factors. This literature survey differs predominantly from other earlier studies in that it provides a comprehensive review of the linkage between government debt and economic growth, in addition to disentangling public debt into two components, domestic and foreign, and expounding on their relative effects on economic growth.
