The purpose of this paper is to examine the impact of agency conflicts between managers and shareholders on corporate risk management and financial performance of Saudi firms listed in the Saudi Stock Exchange Tadawul.

To investigate the effect of agency conflicts between managers and shareholders on corporate risk management and financial performance, we use a sample of 180 Saudi firms listed in the Saudi Stock Exchange Tadawul during the period from 2009 to 2018. Econometrically, we employ Vector Autoregressive (VAR) and General Linear Model (GLM) techniques as an appropriate methodology.

Our findings show that the risk level of the last year increase the corporate risk management and the performance of Saudi firm. We remark that the separation amongst control and ownership generates agency conflicts amongst managers and shareholders which can affect their behavior in decision-making and performance of the Saudi firms. Thus, the conflicts of interest arise from the differences among the work horizon, the risk assumed, the performance of enterprises, and the level of remuneration desired by the managers and shareholders in the case of Saudi firms.

The main contributions of our paper prove that the deepen the study of agency costs linked to a shareholding structure through the analysis of monitoring, obligation, and opportunity costs in the Saudi firms.

The purpose of this paper is to examine empirically the impact of COVID-19 pandemic news in USA and in China on the dynamic conditional correlation between Bitcoin and Gold.

This paper offers a crucial viewpoint to the predictive capacity of COVID-19 surprises and production pronouncements for the dynamic conditional correlation (DCC) among Bitcoin and Gold returns and volatilities using generalized autoregressive conditional heteroskedasticity-DCC-(1,1) through the period of study since July 1, 2019 to June 30, 2020. To assess the unexpected impact of COVID-19, this study pursues the Kuttner’s (2001) methodology.

The empirical findings indicate strong important correlation among Bitcoin and Gold if COVID-19 surprises are integrated in variance. This study validates the financialization hypothesis of Bitcoin and Gold. The correlation between Bitcoin and Gold begin to react significantly further in the case of COVID-19 surprises in USA than those in China.

This paper contributes to the literature on assessing the impact of COVID-19 confirmed cases surprises on the correlation between Bitcoin and Gold. This paper gives for the first time an approach to capture the COVID-19 surprise component. Also, this study helps to improve financial backers and policymakers' comprehension of the digital currencies' market elements, particularly in the hours of amazingly unpleasant and inconspicuous occasions.

This paper provides an important perspective to the predictive capacity of Fed and European Central Bank (ECB) meeting dates and production announcements for the dynamic conditional correlation (DCC) between Bitcoin and energy commodities returns and volatilities during the period from August 11, 2015 to March 31, 2018.

To assess empirically the unanticipated component of the US and ECB monetary policy, the authors pursue the Kuttner's approach and use the federal funds futures and the ECB funds futures to assess the surprise component. The authors use the approach of DCC as introduced by Engle (2002) during the period from August 11, 2015 to March 31, 2018.

The authors’ results suggest strong significant DCCs between Bitcoin and energy commodity markets if monetary policy surprises are incorporated in variance. These results confirmed the financialization of Bitcoin and commodity energy markets. Finally, the DCC between Bitcoin and energy commodity markets appears to respond considerably more in the case of Fed surprises than ECB surprises.

This study is a crucial topic for policymakers and portfolio risk managers.

This paper aims to provide an important perspective to the predictive capacity of Organization of the Petroleum Exporting Countries (OPEC) meeting dates and production announcements for energy futures (crude oil West Texas Intermediate (WTI), gasoline reformulated gasoline blendstock for oxygen blending (RBOB), Brent oil, London gas oil, natural gas and heating oil) market returns and volatilities.

To examine the impact of OPEC news on energy futures market returns and volatilities, the authors use a conditional quantile regression methodology during the period from April 01, 2013 to June 30, 2017.

From the empirical findings, the authors show a conditional dependence between energy futures returns and OPEC-based predictors; hence, the authors can find clear the significance of relationship in the process of financialization of the OPEC announcements and energy futures in the case of this paper. From the quantile-causality test, the authors find that the effect of OPEC news is important to energy futures. Specifically, OPEC announcements dates predict the quantiles of the conditional distribution of energy futures market returns.

The authors confirm the presence of unidirectional nexus between OPEC news and energy commodities futures in the long term.

The purpose of this study is to illuminate financial commitment of a firm vis-a-vis corporate behavior of 519 reported fabric businesses in G-20 states. This study also aims to take into account the regional baseline comparisons (i.e. subsampling) of G-20 firms based on the available data. The pattern of the current study comes from the registered companies in the G-20 states. For the fabricating business, the 2007–2018 annual financial statements are obtained from the Thomson Reuters Data Stream and World Stock Exchange.

For the investigation, the panel data were analyzed from the period 2007–2018 by applying summary statistics of ordinary least square, correlation matrix and generalized method of moments.

The findings of this study suggest that Ln assets, dividends and investments have a positive association with the debt level. In addition, profitability and working capital were negatively associated with change in total debt under pecking order theory.

The effects of the geographical location of the firms and current global economic downturn were accounted for the capital structure decisions and corporate performance of G-20 firms.

This study instigates observed phenomenon elicited from capital structure theory by applying analytical method, instead of describing them in terms of administrative selection, taking measure and chief financial officers risk preference. Finally, work is required to form new hypothesis and explore novel factors that could enrich academic scholars’ motivation.
