Why Private Data Cannot Fully Replace Official Data

The US Congress failed to either change the rules or come to an agreement to avert a government shutdown. Economists now lack official economic data from the US. Private sector data is a poor substitute. Private data is like viewing the economy through a keyhole —clear, but with a narrow field of vision. Official data is like opening the door. Private data relies on official data to model the bits of the economy outside its field of vision, and that modelling becomes less accurate in the absence of official data.
