Given the many activities of Nigerian investors in the crypto ecosystem, this paper investigates the level of their awareness, attitudes, risk tolerance, experience, reasons for investing and level of financial literacy.

The research approach is based on a self-administered questionnaire. The Organization for Economic Cooperation and Development (OECD) permitted the use of its reliable and validated survey instrument, administered in Malaysia, the Philippines and Vietnam in 2019. The results are tabulated and analyzed.

The key results include the participation of respondents, who are generally young males, not fully financially literate but risk-averse. Many held the false view that investing in global markets is a higher risk than in national markets. Their reasons for investing in crypto include the fear of missing out on good opportunities and the desire to have fun. The results also revealed that social media, conversations with non-experts and online articles are among the most used investment information sources, highlighting the role of digital platforms and informal discussions in shaping perceptions and knowledge about cryptocurrencies. Investments in cryptos are financed through savings, regular monthly budgets or borrowed from friends or family. As for specific attitudes to risk, the results suggest that for most respondents, preserving their invested capital is of paramount importance.

The importance of this research also resides in the possibility of comparing the crypto ecosystem in Asia with Nigeria because the same OECD data instrument is employed in data collection. Moreover, this study is the most comprehensive research about Nigerian investors in cryptocurrencies.

This study aims to explore the possibility that securities markets in selected African countries of Egypt, Kenya, Nigeria and South Africa play a significant role in capital accumulation using panel data analysis. This is done by exploring the relationship between gross fixed capital formation on the one hand and financial market development indicators on the other hand. Thus, the study aims to examine if stock market size and liquidity are determinants of capital accumulation.

The analysis is based on annual times series from 1991 through 2017 spanning four African stock markets. The analysis utilizes the fixed-effect and random-effect econometric models. The Durbin–Wu–Hausman test is used to choose between the two models.

The key results indicate that stock market capitalization is a positive determinant of gross fixed capital formation. The market value traded and turnover have no relationship with capital formation. Therefore, the role of stock African stock markets in promoting capital accumulation and, subsequently, industrial growth in Africa is seriously questioned.

Only a handful of studies have examined the role of the African securities market in promoting capital accumulation. This study is unique in which it focuses on the leading stock markets in the four corners of Africa. The markets are from Egypt in the north, South Africa from the south, Nigeria from the west and Kenya from the east. These four markets account for a significant segment of all African markets.

The study aims to examine the appropriateness of the coefficient of elasticity of trading (CET) as a measure of liquidity using Nigerian stock market data. Given that liquidity is multidimensional, the CET is complemented with the popular measure of liquidity, turnover ratio to explore the causal relationship among the CET, turnover ratio and market return to determine their relevance in security valuation. In other words, an attempt is made to examine if either of these two measures of liquidity is a relevant factor in explaining stock market return.

The Toda-Yamamoto version of Granger causality test is applied to two sets of data on the Nigerian Stock Exchange (NSE). The available monthly time series data are from 2008 to 2019 while the annual data are from 1986 to 2018. The Toda-Yamamoto test is preferred because it is more robust to integration and cointegration of the variables.

The results of the Toda-Yamamoto version of the Granger causality test on monthly data reveal no causal relationship between CET and market return, turnover and market return and CET with turnover and market return. These results are consistent with those for several frontier countries reported by Rubio et al. (2005), Hartian and Sitorus (2015), Batten and Vo (2019) and Sterenczak et al. (2020). The results support the conclusion that the Nigerian economy is not fully integrated with the global economy. Market inefficiency due to order imbalances given the nature of the trading system can also explain the reported results. However, the results from annual data do not tally with the monthly results. There is causality running from CET to market return. There is also causality running from turnover to market return. Therefore, both CET and turnover are statistically significant causal predictors of market return. The results from annual data are consistent with those reported by Marozva (2019).

The key limitation is availability of high-frequency transaction-level data to researchers to consider many measures of liquidity that have been employed in developed countries. The research implication is that more researchers will be encouraged to conduct more studies on liquidity and how the study results can drive policy recommendations. The standard asymptotic distribution of underlying the Toda-Yamamoto approach has been found to lead to overrejection.

This study is the first to apply Toda-Yamamoto model on data from Nigeria to investigate the causal relationship between stock market return and liquidity proxied by the CET given the nature of the automated trading system (ATS) in use. The CET is also complemented with the turnover ratio to explore the multidimensional nature of liquidity and its causal relationship with market return. The study is also interpreted as a determination of the integration of Nigeria's economy with the global economy with its implication on investment diversification.

The purpose of the paper is to identify the key determinants of stock market performance in Nigeria. More specifically, it is an attempt to determine the effect of gender diversity in leadership roles on the performance of the stock market in Nigeria.

The paper uses annual data from 1980 through 2011 to model the development and performance of the Nigerian stock market through a modified Calderon-Rossell approach. Specifically, the leadership role of women in the governance of the stock market is investigated. Robust regression approach is used to avoid complications associated with the violations of the assumptions underlying the application of ordinary least squares regression.

The empirical analysis shows that level of income, real exchange rate, liquidity, banking sector development, institutional quality, macroeconomic stability and gender are important determinants of stock market performance in the Nigerian stock market. Further, the results indicate that at worst, gender diversity does not play into stock market performance in Nigeria, and at its best, the appointment of women in the management of the Nigerian Stock Exchange is associated with better performance.

The paper contributes to the empirical literature on the role of gender diversity and financial performance. The contribution of this paper is the inclusion of gender as an institutional factor among the determinants of stock market performance in Nigeria.

This paper seeks to characterize the behavior of the naira/dollar foreign exchange rate series over the period 1999 through 2006 to determine if the process generating the series has long memory which is a special case of fractional Brownian motion. The existence of long memory contradicts the notion of market efficiency.

The paper employs the modified rescaled range R/S test which is proposed by Lo to test the null hypothesis that daily and weekly NGN/USD exchange rates from 1999 through 2006 exhibit short‐memory process. The second test that was also employed is the Geweke‐Porter‐Hubak (GPH) test which was refined by Hurvich et al.

The results show that long memory is present in daily and weekly foreign exchange level series of the Nigerian naira for the period sampled. This evidence implies that the Nigerian foreign exchange market may not be efficient. Thus, it is possible for investors to realize abnormal profit by taking an investment position based on predicted exchange rates. The results reported in this paper are also indicative of a deviation from long‐run PPP.

This paper is the first to empirically apply the modified R/S and GPH tests to explore the existence of long‐memory process in a country study of foreign exchange series using data from Nigeria.

The purpose of this paper is to investigate if the prevalence of corruption and other unwholesome financial practices in Nigeria contributed substantially to the stunted growth of the capital market in general, and the stock market in particular.

The paper employed Gregory–Hansen cointegration approach to test the long-run equilibrium relationship between the occurrence of predatory banking practices and stock market capitalization in Nigeria.

There exists a long-run equilibrium relationship between bank fraud and stock market capitalization but with a structural break in 2005.

There is an urgent need to overhaul and re-assess from time to time the existing systems of internal checks and controls in banks, as well as other financial institutions in Nigeria.

This paper is the first to empirically test the long-run equilibrium relationship between bank fraud and stock market capitalization in Nigeria.

The financial economics literature points to the likelihood that transparency affects the inflows of direct foreign investments. The purpose of this paper is to examine the relationship between degree of transparency in an economy and the level of foreign direct investment (FDI) inflows using cross-section and time series data from 13 Sub-Saharan African countries from 1998 through 2008.

The paper employed a panel unit root and panel cointegration tests to data from 13 Sub-Saharan countries from 1998 through 2008. The long-run equilibrium relationship is estimated by the fully modified ordinary least squares (FMOLS) method. The cointegration framework employed in this study accounts for individual as well as time effects by adjusting for potential heterogeneity and serial correlation existing in the data panel.

The results imply that the level of transparency and size of FDI inflows into Sub-Saharan Africa have a long-run equilibrium relationship.

The role of multinational corporations in increasing the levels of corruption in host countries is supported in this study.

The role of multinational corporations in contributing to the absence of transactional transparency in host countries is supported in this study. The OECD Convention on Combating Bribery of Foreign Public Officials in International Business Transactions should be endorsed by African countries. African countries should make efforts to transform their domestic political and economic environments in order to enhance transparency and allow rule of law to apply.

This paper is the first to empirically test the aforementioned long-run equilibrium relationship by isolating the role of transparency in international capital flows.
