The rise of new technologies is changing the way companies raise funds. Along with increased popularity of crowdfunding in recent years, a new form of funding has emerged – that is, the use of Initial Coin Offerings, or ICOs. In 2017, companies in the United States raised over $4 billion through ICOs; in 2018, more than $21 billion has been raised. ICOs generate many challenges for securities regulators, and also give rise to other issues including corporate governance, data protection, anti-money laundering and insolvency. Assistant Professor Aurelio Gurrea-Martínez from the SMU School of Law has conducted legal research on financial regulation. In this podcast, he shares his recent comparative and interdisciplinary study which addresses the issue of ICOs and makes recommendations to regulators and policy makers in a way that aims to promote innovation and firms’ access to finance without harming investor protection, market integrity and the stability of the financial system.

Assistant Prof Liang Hao – Corporate Social Responsibility, or CSR in short, is an evolving business practice that incorporates sustainable development or ‘doing good’ into a company's business model. In today's socially conscious environment, customers and employees place a premium on spending their money with or working for businesses that prioritise CSR. As such, socially responsible companies can cultivate positive brand recognition, increase customer loyalty, and attract top-tier employees. Taking a fresh approach on CSR research, Assistant Professor of Finance and DBS Sustainability Fellow LIANG Hao from the SMU Lee Kong Chian School of Business, has written two award-winning papers that studied how a firms’ CSR behaviour can influence that of its suppliers as well as its peer firms. In this podcast, he shares the findings and implications of these studies.

Building on research conducted in 2018 on the clear and positive link between high levels of psychological safety and a strong teamwork culture, Richard Smith, Professor of Strategic Management and Deputy Dean (Programmes) at the SMU Lee Kong Chian School of Business, has now dug deeper by focusing on diversity. How does closing the gender gap within organisations in Asian countries impact overall company performance? Are employees more productive, or less, with a sense of belonging to the workplace? In this podcast, Professor Smith discusses the key findings of his research conducted in collaboration with consultancy group Great Place to Work Institute Singapore. The rigorous study, one of the largest in Asia to highlight gender differences, surveyed over 400,000 employees from more than 800 organisations located across eight countries in the Asia Pacific.
