Crowding Out Effect Explained | Macroeconomics

The crowding out effect explains why $500 billion of government stimulus can end up delivering only about $200 billion of actual boost — here’s the mechanism behind it. You’ll learn how a deficit gets financed by borrowing, why government bonds and private loans draw from the same limited pool of savings, and how the loanable funds market turns that competition into higher interest rates. I walk through the complete example with actual numbers: a $500 billion deficit shifts the supply of loanable funds left, the real interest rate gets bid up from 4% to 5.5%, and private investment falls from $1,200 billion to $900 billion — $300 billion crowded out. I also cover why a single firm shelves a 5% project once borrowing costs hit 5.5%, the long-run cost to productive capacity, why the early 1980s and 2009 produced very different results from similar deficits, and three things that change the picture: foreign capital, central bank policy, and what the borrowing actually pays for. Whether you’re studying macroeconomics or just trying to make sense of the next big spending package, this video gives you everything you need to understand the crowding out effect.
