Questions: a. Which can cause a shift in the demand curve? A change in one of the determinants of demand the cost of production the price of a good the technology used by firms

The answer is: A change in one of the determinants of demand.

Explanation for each option:

1. A change in one of the determinants of demand: This is correct. Determinants of demand include factors such as consumer income, tastes and preferences, prices of related goods (substitutes and complements), expectations of future prices, and the number of buyers in the market. A change in any of these factors can cause the demand curve to shift either to the right (increase in demand) or to the left (decrease in demand).

2. The cost of production: This is incorrect. The cost of production affects the supply curve, not the demand curve. If the cost of production changes, it will shift the supply curve because it affects the quantity of goods that producers are willing and able to sell at different prices.

3. The price of a good: This is incorrect. A change in the price of a good causes a movement along the demand curve, not a shift of the demand curve. When the price of a good changes, the quantity demanded changes, but the demand curve itself does not shift.

4. The technology used by firms: This is incorrect. Technological changes affect the supply curve, not the demand curve. Improvements in technology can make production more efficient, leading to an increase in supply, which shifts the supply curve to the right.

In summary, a shift in the demand curve is caused by changes in the determinants of demand, not by changes in the cost of production, the price of a good, or the technology used by firms.
