GDP

noun

1. Initialism of gross domestic product.

   “Economics is a messy discipline: too fluid to be a science, too rigorous to be an art. Perhaps it is fitting that economists’ most-used metric, gross domestic product (GDP), is a tangle too. GDP measures the total value of output in an economic territory. Its apparent simplicity explains why it is scrutinised down to tenths of a percentage point every month.”

   “Or take Wikipedia. Supported by investments of time rather than money, it has left the old Encyclopedia Britannica in the dust – and taken the GDP down a few notches in the process.”

2. Initialism of guanosine diphosphate, a nucleotide.
