Why is the loss from destruction of many old houses in a natural disaster not fully shown in GDP?

Correct answer: Because GDP measures current production flow and not the full loss of existing asset stocks

The governing concept is the distinction between a flow and a stock. GDP records the value of final goods and services produced during a period, so it is a flow measure. The destruction of old houses is a loss of existing wealth or an asset stock; it was not necessarily current production in the period. Therefore option D is correct. Reconstruction may later raise GDP, but that does not erase the original stock loss.
