Document Summary

Ec140 class 9 output and prices in the short run chapter 23. An exogenous change in the domestic price level changes equilibrium real gdp in the opposite direction. The money that people hold can buyer few goods. Increase prices to p1 which decreased expenditure and therefore ae. Ad curve shows level of real gdp for each price level where ae = actual gdp. Equilibrium output from the simple macro model for each price level. All three changes mean that as prices rise, real gdp falls. If ae shifts up, ad increases and the ad curve shifts right. Shift derived from simple multiplier = 1/ (1 z) The govt increases govt spending while also reducing tax rates, this results in a shift right of the ad curve. As curve shows for each price level the amount of output firms would like to produce and sell. Horizontal supply curve means companies can produce however much they want.
