FACTOR DEMAND DETERMINANTS: The three most important determinants that shift the factor demand curve are: (1) product price, (2) factor productivity, and (3) prices of other factors. Like any determinant, these three cause the factor demand curve to shift to a new location. An increase in factor demand is a rightward shift of the factor demand curve and a decrease in factor demand is a leftward shift.
