In 2305 we looked briefly at the budgeting process and will also look at economic policy making soon enough. Both make use of numbers that purport to tell us how the economy is doing - but here's a suggestion that those numbers are misleading.

We act as if they are markers from time immemorial, but in fact they were invented for modern industrial nations after the Depression and World War II and are now seriously outdated.
Take gross domestic product. Derived from formulas set down by the economist Simon Kuznets and others in the 1930s, its limitations have long been recognized, none more eloquently than by Robert F. Kennedy in a famous speech in 1968 when he declared that it measured everything except that which is worth measuring.
GDP treats all output as a positive. When you buy LED lights that obviate the need to spend on incandescent bulbs and reduce energy consumption, GDP goes down and what should be an unmitigated good becomes a statistical negative. If a coal company pollutes a river, the cleanup costs are positive for GDP, as are any health care costs for those harmed.
What’s more, we have also come to assume that with output comes more spending and employment, but factories today are powered by robotics and software, and robots don’t buy more lattes and shoes.
GDP is a good number for a nation that produces lots of stuff made by lots of workers, but for an information economy grounded in services and intellectual property and awash in apps that cost nothing yet enable commerce, it is not up to the task. Nor are many of our indicators. Our trade figures treat an iPhone made—more accurately, assembled—in China with no reference to the intellectual property created by Apple in California.
