Effects on Supply Curve

The video tutorial explains the factors that shift the supply curve, focusing on changes in costs due to technological innovations, input prices, taxes, subsidies, expectations, and the entry or exit of producers. It highlights how these factors affect a firm's costs and, consequently, the supply curve. Examples include the impact of genetically modified seeds on supply and how taxes and subsidies alter costs. The tutorial also covers the role of expectations and opportunity costs in supply shifts, emphasizing understanding over memorization.

Which of the following is NOT a factor that can shift the supply curve?

• Technological innovations

• Changes in consumer preferences

• Input prices

• Taxes and subsidies

What happens to the supply curve when a technological innovation reduces production costs?

• The supply curve shifts up and to the left.

• The supply curve shifts down and to the right.

• The supply curve remains unchanged.

• The supply curve shifts up and to the right.

If the price of an input increases, what is the likely effect on the supply curve?

• The supply curve shifts down and to the right.

• The supply curve shifts up and to the left.

How does a tax on output affect the supply curve?

• It shifts the supply curve up by the amount of the tax.

• It shifts the supply curve down by the amount of the tax.

• It does not affect the supply curve.

• It shifts the supply curve to the right.

What is the effect of a subsidy on the supply curve?

• It shifts the supply curve up by the amount of the subsidy.

• It does not affect the supply curve.

• It shifts the supply curve down by the amount of the subsidy.

• It shifts the supply curve to the left.

How can expectations about future prices influence the current supply curve?

• Expectations have no effect on the supply curve.

• Expectations of higher future prices can decrease current supply.

• Expectations of stable future prices can decrease current supply.

• Expectations of lower future prices can increase current supply.

What happens to the supply curve when new producers enter the market?

• Sunk cost

• Opportunity cost

• Variable cost

• Fixed cost
