Final answer:
All options presented (changes in the sellers' expectations, increases in taxes per unit of output, advances in technology) will shift the supply curve rather than cause a movement along it.
Step-by-step explanation:
The student has asked which of the following will not cause a movement along the supply curve: 1) Changes in the sellers' expectations. 2) Increases in taxes per unit of output. 3) Advances in technology. 4) All of these. A movement along the supply curve occurs only with changes in the price of the good itself. However, things like changes in sellers' expectations, government policies, or advances in technology are factors that shift the entire supply curve, not just cause movement along it.
Changes in sellers' expectations, such as a change in producers' price expectations, can cause the supply curve to shift. For example, if sellers expect higher prices in the future, they might decrease supply now, shifting the supply curve to the left.
An increase in taxes per unit of output typically increases costs for producers and would shift the supply curve to the left, as producers would supply less at every price level.
An advance in technology usually decreases production costs, resulting in an increased quantity supplied at every price level, illustrated by a rightward shift of the supply curve.
Therefore, the answer is 4) All of these as none of these factors will cause a movement along the supply curve; instead, they will shift the supply curve to a new position.
