1.2.4 Supply

Question 1

What is the Distinction Between Movements Along a Supply Curve and Shifts of a Supply Curve?

Answer 1

1. Movements Along a Supply Curve

Movements along a supply curve occur when the quantity supplied changes in response to a change in the price of the good or service, while other factors remain constant.
The law of supply states that, all else being equal, as the price of a good or service increases, the quantity supplied also increases, and vice versa.
2. Shifts of a Supply Curve

Shifts of a supply curve occur when factors other than price cause a change in the quantity supplied at every price level.
A shift indicates a change in overall supply, not just a response to price changes.

Question 2

What are some Factors That May Cause a Shift in the Supply Curve?

Answer 2

1. Production Costs: Changes in the cost of inputs such as labor, raw materials, and energy can affect supply.
   Example: A significant increase in the price of crude oil can increase production costs for many industries, affecting their supply.
2. Technological Advancements: Technological improvements can lower production costs and increase supply. Example: Advancements in manufacturing technology have reduced the cost of producing consumer electronics, leading to increased supply and lower prices.
3. Government Policies and Regulations: Government policies, such as taxes, subsidies, and regulations, can impact supply. Example: Subsidies to farmers may increase the supply of agricultural products, while strict environmental regulations may reduce the supply of certain industrial goods.
4. Natural Disasters and Weather Conditions: Natural disasters, like hurricanes or droughts, can disrupt production and reduce supply. Example: A drought in a major wheat-producing region can reduce the supply of wheat, leading to higher prices.
5. Changes in Expectations: Producers may adjust their supply based on their expectations of future prices or market conditions. Example: If farmers expect coffee prices to rise in the future, they may reduce current supply to take advantage of higher prices later.
6. Government Intervention in International Trade: Trade policies, such as tariffs and quotas, can affect the supply of imported goods. Example: Imposing tariffs on steel imports can reduce the supply of foreign steel in the domestic market.
7. Natural Resource Availability: The availability of natural resources, like minerals and fossil fuels, can impact supply. Example: Depletion of oil reserves can lead to a reduction in the supply of oil, affecting energy markets.
8. Productivity: the productivity of labour or of capital can cause changes in output without changes in the cost of production. This can cases a shift in the supply curve
