When a Closed Economy Is Compared with an Open Economy

When a closed economy is compared with an open economy, what situation exists?

A) Economic activity is directed entirely by the state in an open economy.
B) Exports and imports are monitored and controlled, so there is never a trade imbalance in a closed economy.
C) In a closed economy, because there are no exports or imports, no international transfers, and no service payments, GDP, GNE, GNI, and GNDI are all equal.
D) GDP is always higher than GNE in an open economy because some goods remain unsold into the next accounting period.
