Understanding finance is really important for macroeconomics. It helps us figure out how markets work and how different factors impact the economy.

We can analyze macroeconomic theories using tools from price theory. This allows us to test predictions and better understand how things like interest rates and asset prices relate to the economy.

The CAPM model has flaws and many people have shifted to using better methods for measuring risk and estimating returns. It's criticized for being too simple and for its dependence on past market prices.

All assets are considered illiquid, meaning they can't always be sold quickly at their current price without costs involved. This changes how we understand and measure the value of assets.

Investors care about liquidity because it affects asset prices and returns. Illiquid assets tend to have lower prices and higher expected returns, especially during market crises.
