Question

the saying \money is a veil.\ means that while nominal variables are the first thing we may observe about an economy, whats important are the real variables and the forces that determine them. money is the principal medium of exchange in most economies. the primary determinant of short - run economic fluctuations is not real variables, but rather changes in the money supply. in the long run money is of no importance to the determination of either real or nominal variables.

Explanation:

The phrase "Money is a veil" implies that nominal variables (related to money - values in current - dollar terms) are what we first notice in an economy, but real variables (adjusted for inflation, like real GDP) and the forces behind them are what truly matter. It reflects the idea that money may seem important on the surface, but the underlying real economic factors are crucial.

Answer:

while nominal variables are the first thing we may observe about an economy, what's important are the real variables and the forces that determine them.
