real balances effect

interest rate effect
as price level decreases consumers demand for money increases.
~interest rates (the price of money) increase
~increased interest rates cause investment components of aggregate demand to decrease
~interest rates (the price of money) increase
~increased interest rates cause investment components of aggregate demand to decrease
foreign purchases effect
…, increase in the price level ( relative to foreign price level) will reduce US exports bc Us products are now more expensive for foreigners and epxand US imports bc foreign products are less expensive for Us consumers. as a consequence, net exports will decrease which means there wil a decrease in the quantity of good and services demanded in the US econony as the price level rises. a decrease in the price level will have opposite effect
