Senior Research Associate Stephen Hoskins CREA The issues facing a growing silver population are gaining ground. Singapore’s baby boomers are now exiting the workforce. Would those approaching retirement have enough resources to maintain their current standard of living? Would future policy changes in healthcare, housing and pension impact their retirement adequacy? Facing a rapidly ageing population, Singapore is presented with urgent policy challenges. Yet there is very little data on the economic, health and family circumstances of older Singaporeans. In response, the Centre for Research on the Economics of Ageing, or CREA, at the Singapore Management University has been collecting monthly data on a panel of Singaporeans aged between 50 and 70 years, resulting in the Singapore Life Panel®, or SLP. SMU’s Prof Bryce Hool and Prof Rhema Vaithianathan detail the methodology by which the SLP was constructed, in a published paper titled High-Frequency Internet Survey of a Probability Sample of Older Singaporeans: The Singapore Life Panel®. In this podcast, Stephen Hoskins, Senior Research Associate at CREA introduces the SLP and how it yields rich and remarkable insights to Singapore’s ageing situation. Additional Info High-frequency Internet survey of a probability sample of older Singaporeans: The Singapore Life Panel - by Rhema Vaithianathan, Bryce Hool, Michael D. Hurd, Susann Rohwedder

The advent of financial technology, or fintech, has created new opportunities, business models, products and services. Fintech innovations have disrupted the financial industry, leading to novel ways of delivering financial services, not only by traditional financial institutions but also by start-ups. There is now a new way of computing that uses extremely small objects called "quantum" that could revolutionise the power and accuracy of computations from artificial intelligence to financial investments. Associate Professor Paul Griffin is a financial technology expert at the SMU School of Information Systems; he is also Director of the Financial Technology track under the SMU Master of IT in Business programme. In this podcast, Prof Griffin, who has started researching into the efficacies of quantum computers, shares his research findings and discusses how he sees quantum computers developing in the near future.
