LOOKING BEYOND GDP

Beyond these more immediate challenges, longer-term threats to the global economy are also looming in the form of climate change issues, rising healthcare costs and ageing societies, and the widening income gap. Indeed, some economists wonder if markets are focusing on the wrong metrics altogether. There has been a growing chorus of voices in recent years questioning whether GDP growth and stock prices are the best indicators to measure economic progress.

“Stock prices and GDP have shortcomings as economic indicators. For instance, rising stock prices in a time of slow economic growth may reflect the search for higher yield rather than a true increase in value of a firm’s assets,” said Dr Joshua Greene, a Visiting Professor who teaches in SMU’s Master of Science in Economics programme.

Another perceived flaw of GDP is that it fails to capture economic sustainability or the relative happiness of a population. Even as GDP expands and stock prices soar, wealth and income inequality has widened in many societies, with the less well-off seeing little improvement in their living standards. According to the latest Credit Suisse Global Wealth Report, the world’s richest one per cent own 44 per cent of global wealth.

Faced with a rapidly-ageing population, Asian countries are also paying more attention to health economics. This carries implications for retirement pensions and healthcare expenditures, both for the government and private employers. Among economists, discussions often revolve around quality-adjusted life years for the elderly. Said SMU’s Assistant Professor of Economics, Zhang Xuan: “We should aim to not only extend one’s life expectancy, but also improve one’s health benefits with their living years.”

Rather than strictly using GDP as a measure of welfare, various solutions have been proposed. Asst Prof Zhang opined that a dual focus on subjective wellbeing and physical health status could help alleviate the social isolation and loneliness experienced by many older adults. To tackle inequality, Dr Greene suggested instituting tax policies to better redistribute wealth from the wealthy to the lower-income groups. He also encouraged countries to take a closer look at their Gini coefficients.

In the same vein, a number of holistic assessments of economic performance have been developed. Metrics such as the Genuine Progress Indicator, the United Nations’ World Happiness Report, the United Nations Development Programme (UNDP)’s Human Development Index, and the Organisation for Economic Co-operation and Development (OECD) Better Life Index are steadily gaining traction.

Coming to grips with how economic, financial and social issues are intertwined, as well as how to measure and analyse them, is thus increasingly on the minds of businesses and policymakers alike. After all, as Assoc Prof Tay said, “The best start to dealing with any phenomenon is to understand it, and to understand a phenomenon, we have to be able to measure it.”
