Which occurrence could cause the demand curve for cars in your city to shift to the left? A layoff of 500 workers at the city's airport.
Out of the choices, a layoff of 500 workers is the only negative impact that would happen. When there is a shift to the left of the demand curve, then there is a decrease in the demand that is needed. Some exmaples of a shift to the left of the demand curve is a decrease in income, decrease in the price of a substitute product or service and the rise in a price of another option. All of these are negatively going to effect consumer demand for a good or service.
