India lost its tag as the ‘world’s fastest-growing economy’ last month as its fourth quarter GDP growth fell to 6.1%, the slowest in two years. Very few economists expected the slowdown. In fact, most waited for the economy to rebound as it quickly healed from the impact of the demonetisation of high-value rupee notes in November. Critics of demonetisation felt vindicated, particularly after GDP figures for the third quarter suggested that the shocking, overnight move to demonetise had very little negative impact.

Yet, for all the sermon delivered by the country’s punditry, the fact remains that macroeconomic forecasting is a lousy business — regardless of who makes the predictions. For one, data cannot prove or disprove any hypothesis as they do not establish causation. The mere fact that growth slowed in the first full quarter after demonetisation does not prove decisively that the slowdown was caused by demonetisation. As some have speculated, the current slump in the growth rate may be a continuation of the trend of slowing growth witnessed even before demonetisation.
