Question

read the headlines and determine the direction the supply curve will shift and the determinant being described.

a fire destroys the crop of oranges in the us.

the government places a 40% tax on all avocados imported from mexico.

suppliers believe the market price for pineapples to increase dramatically as pineapples are shown to help fight the coronavirus.

new machinery allows farmers to pick and preserve oranges at a more rapid pace.

the labor costs for mechanics falls from $15 per hour to $10 per hour on average, allowing shop owners to hire more workers.

number of producers labor productivity producer expectations government taxes and regulation cost of inputs technology

Explanation:

• For "A freeze destroys the crop of oranges in the US":
• A freeze reduces the quantity of oranges available. This means less supply at every price level. So, the supply curve shifts to the left. The determinant is the number of producers (since the freeze affects the producers' ability to supply oranges).
• For "The government places a 40% tax on all avocados imported from Mexico":
• A tax increases the cost of supplying avocados. Producers will supply less at each price. The supply curve shifts to the left. The determinant is government taxes and regulation.
• For "Suppliers believe the market price for pineapples to increase dramatically as pineapples are shown to help fight the coronavirus":
• If suppliers expect a higher price in the future, they may reduce current supply to sell more at the higher price later. The supply curve shifts to the left. The determinant is producer expectations.
• For "New machinery allows farmers to pick and preserve oranges at a more rapid pace":
• New machinery (technology) improves efficiency. Producers can supply more at each price. The supply curve shifts to the right. The determinant is technology.
• For "The labor costs for mechanics falls from $15 per hour to $10 per hour on average, allowing shop owners to hire more workers":
• Lower labor costs (cost of inputs) mean lower production costs. Producers can supply more at each price. The supply curve shifts to the right. The determinant is cost of inputs.

Answer:

• A freeze destroys the crop of oranges in the US: Shift - Left, Determinant - Number of Producers
• The government places a 40% tax on all avocados imported from Mexico: Shift - Left, Determinant - Government taxes and regulation
• Suppliers believe the market price for pineapples to increase dramatically as pineapples are shown to help fight the coronavirus: Shift - Left, Determinant - Producer expectations
• New machinery allows farmers to pick and preserve oranges at a more rapid pace: Shift - Right, Determinant - Technology
• The labor costs for mechanics falls from $15 per hour to $10 per hour on average, allowing shop owners to hire more workers: Shift - Right, Determinant - Cost of inputs
