OK, you just opened up a wormhole. Here you go!

These are also great. More like short little videos over very specific topics.

And some more...
Now specifically on the macro side, I do have two books I highly recommend. These books include macro-economics, trading, politics and history.
The first one is:
"Mobs, Messiahs and Markets" By William Bonner and Lila Rajiva
And the second one is like a Market Wizards for the intellectual crowd. Read it twice:
"The Invisible Hands", by Steven Drobny
Now this third item is also a must have. These are audio files you can download and listen to from virtually every, and I do mean every economist on the face of the earth covering every, yes every imaginable topic you can possible think of.
