RAISING the standard of living is not just an economic imperative but a moral one too, a leading political economist from Harvard said yesterday.
Harvard University economics professor Benjamin Friedman said that economic stagnation could lead to adverse effects on a society's ability to create opportunities, level of tolerance and even its capacity for generosity and fairness.
Drawing from more than a century's worth of data from the United States, Prof Friedman showed that there was a correlation between the growth of median incomes and the population's level of tolerance towards immigrants as well as general civility.
For instance, when income levels were stagnant in the late 19th century, there was a wave of violence against immigrants in the US. But when incomes rose, immigrants were more welcome in the country.
In more recent history, he noted that median incomes in the US have all but stagnated in the past 20 years or so. In 1993, median incomes were about US$56,600. This rose to US$66,300 in 2000 but has since fallen to US$61,000 in 2011.
As a result, there was a corresponding rise in political gridlock, the erosion of civility, a rise in anti-immigration sentiment as well as a fracturing of racial and religious tolerance in the US in the past few years.
"These trends occur repeatedly over time. The alignment between economic growth and social political movements is unmistakable," he said at a talk in the National University of Singapore (NUS).
"Economic growth is something to be supported and morally desired."
One big reason for these trends is that if people feel that they are not doing as well as they previously did, and are not progressing compared with others, then there is less chance of them being generous and fair, said Prof Friedman, who was appointed by the Monetary Authority of Singapore as its Term Professor in Economics and Finance last week.
The implications for economic planning are wide. For instance, if economic growth is seen as morally good, then policymakers should be framing economic policies that support both growth and wider social goals.
