What differentiates between export sales and GDP? Domestic tourism?
Good question - it should be a similar absolute number, but GDP is measured as percentage of total output, whereas percentage of export sales is only percentage of their exports.
The only way I can understand that Israel is both 5% of GDP and 5% of export sales is if export sales is measuring revenue on a broader basis than GDP, but it's more likely my numbers are wrong.
The point is probably still true, Iceland needs tourism for Forex much more than Israel does, because Israel get far more Forex from other exports
