Does GDP Present an Accurate Picture of the Economy? Not Likely
To understand the economy, most financial experts and commentators rely upon gross domestic product (GDP). The GDP framework looks at the value of final goods and services produced during a particular time interval, usually a quarter or a year.
This statistic is constructed with the view that consumption, not wealth production, drives an economy. Since consumer outlays are the largest part of the overall demand, it is assumed that consumer demand drives economic growth, a fundamental assumption in Keynesian economics.
