In a provocative new study, a pair of Nobel prize-winning economists, Joseph E. Stiglitz and Amartya Sen, urge the adoption of new assessment tools that incorporate a broader concern for human welfare than just economic growth. By their reckoning, much of the contemporary economic disaster owes to the misbegotten assumption that policy makers simply had to focus on nurturing growth, trusting that this would maximize prosperity for all.
“What you measure affects what you do,” Mr. Stiglitz said Tuesday as he discussed the study before a gathering of journalists in New York. “If you don’t measure the right thing, you don’t do the right thing.”
According to the report, much of the world has long been ruled by an unhealthy fixation on swelling the gross domestic product, or the quantity of goods and services the economy produces. With a singular obsession on making G.D.P. bigger, many societies — not least, the United States — failed to factor in the social costs of joblessness and the public health impacts of environmental degradation. They allowed banks to borrow and bet unfathomable amounts of money, juicing the present by mortgaging the future, thus laying the ground for the worst financial crisis since the 1930s.
