Teaching a course on international economics (trade and finance) for international relations students. More on that later. Just wanted to post the exports to GDP ratio for the world.
This is to give students a sense of the increase in trade in the last few decades, and also the relative stagnation since the 2008 Global Financial Crisis. Note that while exports are about US$ 23 trillion in a year, the daily turnover in the foreign exchange market is about US$ 5 trillion.
