The Real-Time Revolution and Digital Economics in the COVID Era

 




Driven by COVID, economists are finally embracing streaming and real-time data — just like the business world

Governments use macroeconomic forecasts to guide their policymaking. Will another interest rate cut jumpstart a flagging economy? How much unemployment will result from raising the minimum wage to X dollars per hour?Prior to the 20th century, classical economists — think Adam Smith or Thomas Malthus — created grand, unified theories. However, data was so scarce and spotty that their treatises read more like philosophy than modern economics. More than half of the economics papers published in the 1970s lacked any numerical data, according to the Economist. Even today, key statistics such as national GDP or unemployment rates take weeks and months to collect, revise, and finalize. More complex figures such as productivity rates take even longerThat time frame is ok for economics professors, but too slow for policymakers. The problem remains two-fold: official government statistics take too long to emerge, especially in crises, and the levers at the disposal of policymakers are too blunt and slow.“Traditional government statistics weren’t really all that helpful — by the time they came out, the data were stale,” a former U.S. assistant treasury secretary told the Economist.Faced with this data dilemma, some economists retreat back to theory and ideology. Supply siders pushed for cutting taxes and regulations, while demand-siders argued for higher taxes and government spending.Others mined real-time indicators such as stock and bond market prices. While these have the virtue of mining the wisdom of crowds, they are also vulnerable to a whole set of accuracy-reducing factors: market manipulation, unwarranted investor confidence or panic, issues particular to one company or industry, etc.Stale Data Costs Trillions of Dollars“It is only a slight exaggeration to say that central banks are flying blind,” wrote the Economist. As a result, “bad and late data can lead to policy errors that cost millions of jobs and trillions of dollars in lost output.”And that’s exactly what happened during the 2008 recession. As TV talking heads referred to stale economic data showing everything was A-OK, housing prices plummeted, foreclosures skyrocketed, and the economy tanked. Banks were too big to fail, until they suddenly weren’t. The lack of reliable, fresh data led to bad policy decisions that worsened the recession.
