The Mundell–Fleming model under a fixed exchange rate regime also has completely different implications from those of the closed economy IS-LM model.

Since under a peg, i.e. a fixed ...
In contrast, a closed economy restricts international trade and finance with other countries. In an open economy, the sale of goods or services to a foreign country is known as exporting, while the purchase of foreign goods or services is referred to as importing.

Therefore the budget is split into revenues, which are the taxes (T), and the spendings, which are transfers (TR) and government spendings (G). Revenue minus spending results in the public (governmental) saving:
