supply-side economics

is the idea that putting more money in people's hands induces more savings (usually among the wealthy), and more savings (deposits in banks) reduces the price of borrowing for everyone, thereby stimulating investment.

All else equal, an exogenous rise in the amount of money saved results in some form of investment in a healthy economy, as it will increase the supply of deposits at banks will reduce the price of borrowing for both the corporate and the household sector, stimulating investment.
