The Relationship

Securitization of the agricultural commodity market has accelerated since the beginning of the 21st century, particularly in the times of financial market uncertainty and crisis. Sugar belongs to the group of important agricultural commodities. The global financial crisis and the COVID-19 pandemic has caused a substantial increase in the stock market volatility. Moreover, the novel coronavirus hit both the sugar market’s supply and demand side, resulting in sugar stock changes. The paper aims to assess potential structural changes in the relationship between sugar prices and the financial market uncertainty in a crisis time. In more detail, using sequential Bai–Perron tests for structural breaks, we check whether the global financial crisis and the COVID-19 pandemic have induced structural breaks in that relationship. Sugar prices are represented by the S&P GSCI Sugar Index, while the S&P 500 option-implied volatility index (VIX) is used to show stock market uncertainty. To investigate the changes in the relationship between sugar prices and stock market uncertainty, a regression model with a sequential Bai–Perron test for structural breaks is applied for the daily data from 2000–2020. We reveal the existence of two structural breaks in the analysed relationship. The first breakpoint was linked to the global financial crisis outbreak, and the second occurred in December 2011. Surprisingly, the COVID-19 pandemic has not induced the statistically significant structural change. Based on the regression model with Bai–Perron structural changes, we show that from 2000 until the beginning of the global financial crisis, the relationship between the sugar prices and the financial market uncertainty was insignificant. The global financial crisis led to a structural change in the relationship. Since August 2008, we observe a significant and negative relationship between the S&P GSCI Sugar Index and the S&P 500 option-implied volatility index (VIX). Sensitivity analysis conducted for the different financial market uncertainty measures, i.e., the S&P 500 Realized Volatility Index confirms our findings.

The Way

Corporate governance can be defined as: the set of processes, customs, policies, laws and institutions affecting the way a company is directed, administered or controlled. Suggestions were investigated that the global financial crisis revealed severe shortcomings in corporate governance. Research was conducted to establish whether these suggestions are accurate. The study found that it appeared that corporate governance has failed and action needs to be taken. The study recommends that a world supervisory body on corporate governance be established. It also proposes that a summit be called to discuss and create such an authority. In addition, the formulation of a set of universal corporate governance standards for implementation by the members was suggested

New Evidence

This study examines the return and volatility transmission between gold and nine emerging Asian Stock Markets during the global financial crisis and the Chinese stock market crash. We use the VAR-AGARCH model to estimate return and volatility spillovers over the period from January 2000 through June 30, 2018. The results reveal the substantial return and volatility spillovers between the gold and emerging Asian stock markets during the global financial crisis and the Chinese stock market crash. However, these return and volatility transmissions vary across the pairs of stock markets and the financial crises. Besides, we analyze the optimal portfolios and hedge ratios between gold and emerging Asian stock markets during all sample periods. Our findings have important implications for effective hedging and diversification strategies, asset pricing and risk management.

Purpose This paper aims to address the evolution of corporate governance in Germany with a particular regard to whether there can be observed a gradual convergence to a shareholder primacy corporate governance system. Design/methodology/approach To investigate a potential shift of the German corporate governance system to an Anglo-American tiled corporate governance system, the authors have empirically assessed on a polynomial base 52 separate company and corporate governance variables for 20 years (1995-2014). Findings This research suggests that a gradual convergence has taken place prior to the global financial crisis. However, the results suggest that the convergence process experienced a slowdown in the aftermath of the global financial crisis, which may be linked to the stability of the German corporate governance system during the global financial crisis and the political environment during this time. Originality/value This paper contributes to the research by not only analysing the development of the German corporate governance system but also identifying new reasons for this development and explaining why a new convergence process may be observed in the future again.
