An innovative study reveals how US tariffs on Chinese goods have disproportionately affected low-income American households, challenging the effectiveness of protectionist trade policies. Research from an international team of scholars, Professors Mingzhi Xu at Peking University, Hong Ma at Tsinghua University, Jingxin Ning at UIBE, and Luca Macedoni at Aarhus University, provides compelling evidence for the benefits of free trade and the often-overlooked costs of trade barriers.

Inventory management is a key activity in many organizations. Its performance is often measured by the inventory turnover ratio metric, or ITR for short. This is a key performance indicator that managers are incentivised to improve. However, improper measurement of the ITR metric can cause problems in terms of reliability, comparison, and bias. Professor Benjamin Melamed of Rutgers University has proposed novel formulations of Little’s Law. The traditional Little’s Law is used an as approximation of real-life measurement, whereas Melamed’s versions are exact and robust.

Whether policymaking can develop solutions for the inevitable problems that capitalism creates has long been a concern of political economists. One of these issues is rising inequality across the USA and other countries. Inequality is a significant risk for political stability, so it is vital to understand how democratic societies respond to it. Progressive taxation policies, which tax the rich at higher rates, can help to equalize incomes and wealth. Despite this, over the last four decades while inequality has increased, successive US governments have introduced falling tax rates for top earners. Why is this?

The role of EU trade policy is evolving in today’s complex global landscape. Dr. Andrea Christou and Professor Chad Damro at the University of Edinburgh have studied how the EU balances traditional market-oriented goals with emerging geopolitical pressures. Their analysis explores how different EU bodies frame trade policy, highlighting the contrast between the EU’s broader geopolitical strategy and its trade department’s narrower approach.

Brazil, Russia, India and China, often known as the BRICs, have seen explosive growth in the past two decades and have asserted themselves as drivers of globalisation. Many scholars have researched the effects of this growth and development, and how these factors have affected domestic labour conditions. But are they asking the right questions? For instance, if developing countries invest in developed economies, will this lead to improved working conditions in the investing developing nation? Dr Patrick Wagner of the University of Konstanz, Germany, and Professor Damian Raess of the Catholic University of Lille, France, have conducted a study investigating whether Brazilian direct investment in Europe leads to improved working conditions back in Brazil.

Businesses today exist in a changing world, which brings both opportunities for growth and increasingly complex challenges. To survive and thrive, organisations need a robust understanding of HR management. In their research, Professor Xiaobei Li and her colleagues at various universities, including University of New South Wales, Arizona State University and Peking University, recently explored how organisations can motivate their staff to ensure high-quality performance.

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.
