In the last few decades, the frequency and intensity of extreme weather events have increased in most parts of the world including Canada because of global warming. The global warming in Canada is about double the magnitude of global warming; therefore, policymakers are concerned about the potential significant impact of the weather catastrophes on the economy and financial sector. The purpose of this study is to explore the impact of weather catastrophes on the Canadian banking sector.

Using a sample of banking firms from Canada over the period 1988–2019, the present study estimates different econometric techniques to investigate the impact of weather catastrophes on the risk and performance of Canadian banks.

Analyses of the study do not find a significant impact of the weather catastrophes on the performance of the Canadian banks; however, it has helped banks to lower their risk level and improve stability due to proactive risk management. The findings of this study are not consistent with concerns of the policymakers about climate risk to the Canadian bank sector. More sector-specific research and policy initiatives are recommended to minimize the future financial risk of the increased frequency and intensity of natural disasters.

The study contributes to support the notion that the climate risk of banks is protected with insurance and reconstruction activities provide more banking opportunities.

The income structure of banks has undergone a notable change in recent decades; therefore, non-interest-based activities have gained much attention. This paper aims to examine the impact of income diversification on bank performance in Pakistan.

A balanced panel data set of 20 Pakistani commercial banks is used from 2007 to 2020. The random effect model is employed to test the relationship between income diversification and financial performance.

The empirical results indicate a significant positive impact of income diversification of banks on risk-adjusted returns on assets and equity. Moreover, while banks' risk-adjusted profit performance improves with the increase in bank size, equity ratio and loan ratio, it deteriorates with high credit risk and technology. However, geographical diversification does not explain financial performance in all the risk-adjusted return on equity models. Among the macroeconomic factors, the interest rate influences bank risk-adjusted returns positively, whereas gross domestic product and inflation rate have a negative effect on banks' financial performance.

To the best of the author's knowledge, this study is the first to empirically investigate the relationships between income diversification and the risk-adjusted profits of Pakistani-listed commercial banks. This study has implications for regulators and policymakers of commercial banks.

This paper contributes to the existing literature by extending the empirical work on the relationship between corporate governance and capital structure by analyzing the mediating role of cost of capital in the non-financial firms listed on the Pakistan Stock Exchange (PSX).

The sample for this study includes non-financial firms listed on the Pakistan Stock Exchange (formerly Karachi Stock Exchange) for the period of 2004–2016. Based on 1800 firm-year observations, three approaches of panel data analysis are applied for the step-wise analysis of the underlying study. Firstly, Pooled OLS is applied. Secondly, fixed and random effect panel regression followed by the Hausman test to check the unobservable individual heterogeneity of the data. Hausman test indicates that the fixed-effects model is the most appropriate model for the sample panel data.

The study's findings are that board size, board composition, CEO/Chair duality, institutional ownership and managerial ownership have statistically significant direct effect on the firm's financing decisions. However, CEO/Chair duality, institutional ownership and managerial ownership have significant indirect effect on firm's capital structure decisions. The interesting finding of the paper is on the evidence of mediating role of cost of capital in the nexus of corporate governance and capital structure. Moreover, some conventional determinants of capital structure, including the firm's size, asset structure of the firm, profitability, business risk and growth, are found as determinants of capital structure decisions of the firms.

There are a few limitations to our study which could be addressed by upcoming research. We did not include all the four mechanisms of corporate governance including board structure, audit structure, compensation structure and ownership structure. However, we used only five important attributes including board size, board composition and CEO/Chair duality form board structure, managerial ownership and institutional ownership form ownership structure of corporate governance as our explanatory variables to examine their impact on the capital structure choices of the firms. Future studies may fill this research gap by involving some other attributes of corporate governance and analyzing their effectiveness and impact on value relevant capital structure decisions. Further, due to limited time and resources, we only tested the mediating role of cost of capital, hence, future researchers can analyze the mediating and moderating roles of different variables which may influence the relationship between corporate governance and capital structure choices of the firms.

The study has many valuable guidelines and practical implications for the financial managers of the corporations. Our results will facilitate the policymakers in setting their corporate governance policies and practices and making the value relevant capital structure decisions in compliance with the implications of corporate governance mechanism. In addition, our study provides the empirical evidence in accordance with the argument that good governance practices, particularly the voluntary disclosures by the firm may reduce the information asymmetry which, ultimately, reduces the agency cost and the cost of capital for the firm. However, while deciding the financial policy of the corporations, managers can use our findings in order to assess the effectiveness of corporate governance practices employed by the firm in achieving the optimal capital structure at which the weighted average cost of capital is at its minimum level.

This paper contributes to the literature by investigating the mediating role of the cost of capital in the relationship between corporate governance and capital structure decisions of the firms. This paper provides empirical evidence that corporate governance indirectly affects capital structure decisions through the mediating role of cost of capital.

Firm performance has become a thriving research field. However, a review of previous studies shows that the answers to several fundamental questions remain vague and require further investigation. Thus, the purpose of this study is twofold. The first is to determine the extent of the involvement of political connections (PCs) in Pakistani-listed companies, and the second is to examine the association between PCs and firm financial performance with director efficacy’s moderating role.

A data set of 221 non-financial companies listed on the Pakistan Stock Exchange for 10 years (2008–2017) was analysed using panel-corrected standard error regression. Additionally, the authors address endogeneity issue by using Hackman two-stage estimation and lagged variables regression.

The study found that PCs negatively affected the firm’s financial performance, and director efficacy as a moderator strengthened this relationship. The result is consistent with the political economy theory that argues that an unstable political system and a weak judicial system will strongly affect investors and their rights.

The impact of political influence on the corporate sector remains a concern for policymakers, regulators, investors, financial experts, auditors and academic researchers. This study’s findings are that an effective board of directors can strengthen the company’s best practices by controlling political connectedness to protect all the interested parties, particularly investors, and restore their confidence. Therefore, the results of this study can assist all stakeholders when a PCs exists to make the right decisions.

The study extends the literature in terms of theoretical contribution that uses an integrative approach to combine political economy theory, agency theory and resource dependence theory to address the moderating role of director efficacy with an association between PCs and firm financial performance. To the best of the authors’ knowledge, no extant research has investigated the association between PCs and firm financial performance using five aspects of PCs, along with moderator director efficacy.
