To improve net exports, some economists believe import compression is the best tool. Worrell 2012 argues that because Caribbean economies can do little to improve inflows of foreign exchange, improving net exports must come about through fiscal policy (i.e. import compression). However, the economy is import driven and imports are critical in the formation of capital and production. So, can import compression achieve the desired impact without negatively affecting the economy? Khan and Knight 1986 say this is not possible, as the reduction in imports also negatively impacts exports.
