Resource prices do not change in the short run but will change in the long run.-resources prices will not adjust immediately; in the short run we say resource prices are fixed. as a result, the sras curve slopes upward because producers will want to sell more goods and services when the price of the goods and services increases because costs will not increase immediately.however, if we wait a longer time period, the price of resources like labor, land, and natural resources will change. when the price of these resources increases, the costs to producers increases. thus, in the long run higher prices are likely to cause higher costs, so producers have little if any incentive to produce more goods and services. that is why the lras curve is vertical.
