Cum-ex trading in European markets has been widespread, in which investors wrongfully receive refunds on dividend withholding tax they have never paid. Moritz Wagner and Xiaopeng Wei at the University of Canterbury and Adelaide recently explored the extent of this trading practice and its impact on markets and tax revenues.

Foreign direct investment occurs when a resident in one economy invests in and establishes significant influence over an enterprise in another economy. In a changing geopolitical landscape, the EU and its member states have introduced novel mechanisms for screening foreign direct investment for national security risks. However, these mechanisms vary substantially in how they operate. In a recent study, Professor Sarah Bauerle Danzman at Indiana University and Professor Sophie Meunier at Princeton University explore the factors that explain this. They also highlight key policy implications in this shift towards a more assertive EU investment policy.

South Africa’s post-apartheid foreign policy has largely emphasised state-led continental political and economic integration. However, little attention has been paid to the influence of the country’s multinational corporations – or ‘MNCs’ – in this process. MNCs have indeed made an important contribution to increased integration across Africa, due to expansion strategies and the desire to increase market share. Dr Mpumelelo Mkhabela and Professor Christopher Changwe Nshimbi from the Centre for the Study of Governance Innovation at the University of Pretoria argue that we should do more to acknowledge this.

In a recent paper, Professor Bertrand Guillotin and Julianne Sellin of Temple University discuss the difficult decision demanded of international companies operating in Russia at the beginning of the Ukrainian invasion. They explore this using the case study of Auchan, an international grocery retailer that had invested huge amounts of resources into the Russian market and had a tough decision to make.

Sustainable Development Goal 12 refers to responsible production and consumption. Professor Rafael Ravina-Ripoll at the University of Cádiz in Spain and his colleagues (Luis Bayardo Tobar-Pesantez, Estela Núñez-Barriopedro and David Almorza-Gomar) have addressed a lack of research and understanding in the literature about how management models based on happiness management can help promote sustainable and ethical development in the COVID-19 era.
