Article
Full-text available
Existing empirical works have investigated the relationship between informality and poverty. However, most of these work have neglected the feedback effect. This empirical paper explores the bi‐directional causality between poverty and informality within the SGMM‐PVAR framework among 40 selected high‐income and low‐income Sub‐Saharan countries betw...
Article
This article examines the threshold effect in the leverage-firm performance nexus. Using the dynamic panel threshold model of Seo and Shin (2016) that allows for the estimation of panel threshold effect in the presence of endogeneity on Nigerian data. Our empirical analysis adopts a large panel dataset of 104 Nigerian firms between 2005 and 2018. T...
Article
This paper examines the effect of competition on nonperforming loans in the Nigerian banking industry between 2011 and 2018 using the system generalized method of moments. The findings establish the competition-stability hypothesis in the Nigerian context. The interaction between competition and bank size/capitalization has a positive and significa...
Article
Using the dynamic panel threshold model, this work examines the nonlinear relationship between financial development and inequality in Africa. The study introduces a robust measure of financial development into the literature. Using 40 African countries selected from high-income, middle-low and low-income countries, the study tests the new financia...
Article
Using a robust firm-level dataset of 896 firms selected from 27 African countries between 2005 and 2017 and generalized method of moments (GMM) technique, this study investigates the firm-specific, the industry-level and the macroeconomic factors affecting firm profitability in Africa. Unlike existing studies that adopt non-standard measures of fir...
Article
Full-text available
This study examines the inter-temporal relationship between nonperforming loans, efficiency and bank capital in Nigeria. First, the study investigates the determinants of nonperforming loans in the Nigerian banking industry after recapitalization policies of 2005 and 2011 using robust measures of nonperforming loans and efficiency. Unlike extant st...
Article
This paper revisits the financial development-poverty nexus. Following Chiak et al, (2013) and Sahay et al., (2015), the study builds a robust measure of financial development that captures the state of financial development in Africa. We adopt the measure for examining the relationship between 1996 and 2015. Our results agree with a priori expecta...
Article
Full-text available
This study examines the threshold effect in the nonperforming loans-profitability nexus within the Nigerian banking industry. Using the innovative dynamic panel threshold of Seo, Kim & Kim (2019), the work documents threshold levels of 3.5% and 5.0% of nonperforming loans for return on average assets (ROAA) and return on average equity (ROAE) respe...
Article
Full-text available
Extant studies on the relationship between financial development and inequality have largely adopted single financial indicators especially the ratio of private credit to GDP. Unlike these works, the present study adopts a robust total financial development indicator based on four mainstays of financial development of financial deepening, efficienc...
Article
Purpose The paper examines whether there is a threshold between financial development and poverty in African economies. Design/methodology/approach The study adopts the innovative dynamic panel threshold model of Seo and Shin (2016) made practicable by Seo et al. (2019)–the model estimates threshold relationship even in the presence of endogeneity...
Article
Full-text available
The bulk of existing studies investigating the relationship between remittances inflows and financial development focus on the effect of the former on latter neglecting the feedback impact. Unlike these studies, this work adopts a robust composite measure of financial development using the World Bank four mainstays to investigate the direction of t...
Article
Unlike extant studies investigating the determinants of capital structure decisions in Nigeria, this paper accounts for the role of persistence in capital structure decisions of Nigerian firms. Using a dataset of 107 firms listed on the Nigerian Stock Exchange (NSE) and innovative technique of system GMM, the study documents firm-level and macroeco...
Article
Full-text available
Using a robust bank-level dataset and system GMM estimation technique, this study investigates the effect of corruption on bank profitability of commercial banks across 38 countries between 2011 and 2017. Grouping these countries according to corruption levels, the study employs Transparency International and the International Country Risk Guide me...
Article
Full-text available
Purpose The purpose of this paper is to re-examine the determinants of bank profitability in Nigeria. Specifically, the study investigates the effect of managerial cost efficiency on bank profitability. Also, since there exist mixed results and controversies in the literature, in both developed and developing countries, regarding the effect of effi...
Article
Full-text available
Studies on the nexus between size and profitability occupy a substantial portion of empirical economic literature; however, the existing literature tilt much in favour of non-financial firms with little attention towards the financial sector, especially in the context of developing countries, most especially, Nigeria. This study examines the causal...
Article
Full-text available
The bulk of extant studies on the relationship between firm size and profitability focus on the effect of former on the latter, neglecting the possibility of feedback effect. This research work re-examines the direction of causality between firm size and profitability for 63 listed non-financial Nigerian firms for the period 1998–2010, using an inn...
Article
Full-text available
The study revisits the concentration–profitability nexus of the structure–conduct–performance (SCP) paradigm. It contributes to the literature by considering the argument from the perspective of causality since existing empirical works only consider a unidirectional relationship of concentration as being determined by profitability, neglecting the...
Article
Full-text available
This empirical study investigates the direction of causality between gross domestic saving and economic growth among the six sub-Saharan African fastest growing economies as reported by African development Bank between 1981 and 2014 using the recently developed methodologies of ARDL and Toda and Yamamoto causality test. The result shows the existen...

Question
One major means of development in academics, for upcoming ones, is to learn from senior academics. However, senior academics often don't have time for junior ones. What are the formidable ways of learning from these invaluable people despite their busy schedules?

Project
The project examines the effects of nonperforming in the Nigerian banking industry. Specifically, this study examines linear and nonlinear effects of 5% nonperforming loans threshold imposed by the Central Bank Prudential Guidelines on the profitability of commercial banks, competition, systemic risk in the Nigerian banking industry and the determinants of Nonperforming Loans in the Post-recapitalization Period in the Nigerian Banking Industry.
Project
This project aims to build a robust financial development indicator applicable in the context of African countries. A major issue with the popular measures of financial development in extant studies on Africa, Ratio of Private credit to GDP and money supply to GDP, is the neglect of the low level of financial inclusion that characterized the continent. In response, the project builds a robust financial sector indicator. This is tested using Remittances, Inequality and poverty in the continent.
Project
This study re-examines the relationship between corruption and bank profitability. Though nascent, the literature on the relationship has largely adopted macroeconomic measures of Corruption (ICRG, WGI), this study re-investigate the relationship using a bank-level proxy for bank corruption.
