It looks like you're asking about a (possibly a re-upload, compressed version, or alternate file format) of Olivier Blanchard’s Macroeconomics , 9th edition.
: Focuses on equilibrium in the goods and financial markets using the IS-LM model .
When Savant acquired the rights to Blanchard’s book, they acquired the content and the copyright , but they did not acquire the Pearson name or logo. The Pearson brand remained with the original Pearson company.
The 9th edition has review questions at the end of every major section (not just the chapter end). Skipping these is a mistake. They build muscle memory for the math.
