The article examines how different unconventional monetary policies can impact an economy. By using a model based on Chile's economy, the researchers found that policies affecting liquidity can have a big effect, depending on expectations about future interest rates. Policies affecting the term premium have smaller effects but are less dependent on expected interest rate changes. Reversing unconventional policies may slow down the economy, especially if anticipated. Keeping interest rates low for a long time can also boost the economy, but credibility issues can weaken this effect.
