Three of the four events described below might reasonably be expected to shift the demand curve for Tacos to a new position. One
would not shift the demand curve. The single exception is: a. a widespread advertising campaign undertaken by the producers of a product competitive with Tacos.
b. an increase in the money income of beef consumers.
c. a change in people's tastes with respect to Tacos.
d. a fall in the price of Tacos.
As there are there to four events that might be reasonable to show the shift in the demands curves and thus one impact of this shift would be a widespread increase in the advertisements and the changs in the tastes of the consumers and the people of the area. Thus the curve will shift to the left side. Will a fall in the prices would not affect the movement to the new location.
