This paper aims to study the effect of Hofstede’s cultural dimensions (power distance, individualism, masculinity, uncertainty avoidance and long-term orientation) on corporate tax avoidance as proxied by the effective tax rate.

A sample of 944 observations during 2016 was analyzed at three different quantiles (Q 0.25, Q 0.50 and Q 0.75) based on a quantile regression approach.

Using Hofstede’s (2001) cultural dimensions (power distance, individualism, masculinity, uncertainty avoidance and long-term orientation), the authors find that individualism and masculinity are negatively associated with effective tax rates, and this negative relationship is more pronounced under low tax aggressiveness regime (third quantile). By contrast, long-term orientation is positively associated with the effective tax rate, and this relationship is more prevailing under aggressive tax regime (first quantile). These findings remain stable when using cash effective tax rate as an alternative measure for tax avoidance.

This study adds to the extant literature a further understanding of the impact of cultural dimensions on tax avoidance. The use of quantile regression approach shows how the effect of masculinity, individualism and long-term orientation on tax avoidance varies under different tax management regimes.

This paper examines the association between the quality of management schools and sustainability and investigates whether ethical behavior of firms moderates relationship between the quality of management schools and sustainability.

The sample consists of 500 country-year observations over the period of 2014-2017. Sustainability is collected from the Global Sustainable Competiveness Index reports for 2014, 2015, 2016 and 2017, while the quality of management schools and ethical behavior of firms are collected from the Global Competiveness Report for the same years.

The findings of this study suggest that the quality of management schools is positively associated with sustainability. When testing for the moderating effect of ethical behavior of firms on the association between quality of management schools and sustainability, results show that the positive association becomes positive and more significant for countries where firms operate with high ethical behaviors, while the association becomes insignificant for settings where firms operate with low ethical behaviors. Findings also show that the quality of management schools and ethical behavior of firms play a complimentary role in improving sustainability.

The findings emphasize the role played by business schools and business ethics in improving sustainability. These results may have policy implications for governments aiming to improve sustainability by emphasizing on education for sustainable development in management schools’ 2019 programs enforcing standards dealing with business ethics and controlling firms’ 2019 compliance with them.

The findings of this study highlight the importance of education, as proxied by the quality of management schools, in the development of sustainable societies and economic systems. To the best of the author's knowledge, this is the first study that tries to empirically link business schools programs to sustainability efforts and how business ethics may affect this association.
