Facts:
1) GDP = Consumer spending + Investment spending + Government spending + Net exports.

2) Net exports are the difference between a country’s exports and imports. 

Analysis:
A country can increase net exports in 3 main ways:

1) Lowering the interest rate. Its drop leads to the country’s currency depreciation*. That decreases the cost of exports for foreigners and hence results in a rise in exports. Therefore, net exports hike. For example, in the U.S. net exports increased during the Great Recession of 2007-2009 due to sharp cuts in interest rates.

Explanation:
All else equal, when the interest rate is lowered => the country’s securities* are less profitable => foreign and domestic investment is discouraged => capital outflow => the supply of the country’s currency increases and demand decreases => the currency depreciates => the cost of exports lowers and cost of import raises => net exports hike. 

2) Decreasing inflationary pressures. A lower price level lowers the cost of exports for foreigners, increasing net exports.

3) Protectionist* policies. Trade barriers such as tariffs and quotas decrease imports, contributing to net exports soaring.
