Book recommendations: National income accounting and IS-LM model Basically I'm interested in solving tricky thought provoking exercises based on National income and on IS LM model. I've read mankiw but it didn't satisfy my needs.
I would suggest:

1) Macroeconomics by Dornbusch and Fisher.

2) Macroeconomics by Richard Froyen

3) The Economics of money and financial markets by Mishkin.

Between the first two books that is Dornbusch and Fischer and Richard Froyen, I am indifferent.  Both are equally good and the only difference is that Dornbusch and Fischer has a slightly more mathematical rigor whereas Froyen is a more story like engaging macroeconomics narrative with fair amount of mathematics.

If you need a truly engaging book,  then go for Mishkin. But I will suggest don't read Mishkin as the first book to understand macroeconomics.
