Welcome everyone! Today, we are diving into how input prices affect a firm's supply curve. Can anyone tell me why input prices might matter?
I think if the prices go up, the firm might not be able to make as much money.
Exactly! When input prices rise, the cost of production increases. This often leads to a leftward shift in the supply curve. How about we think of a mnemonic? 'Higher Costs, Less Output'—that can help remember how increased input prices affect supply.
So, if the input prices go down, does that mean they can supply more?
Yes, correct! A decrease in input prices allows firms to produce more at the same price level—this shifts the supply curve to the right. Great work!
Now, let’s discuss what happens to the market when input prices fluctuate. Why do you think firms react in such ways?
They need to maintain their profits, right?
Exactly! If the firm's costs rise too much, they might reduce production. If you think about it, this is a safeguard for their margins. Who can remind me of the relation between cost and supply?
If costs go up, supply goes down.
Spot on! Remember, the goal is always profit maximization. Let’s summarize—higher input prices lead to lower supply while lower input prices lead to higher supply.
Let's apply what we've learned. Can anyone think of a situation where input prices have significantly changed?
Maybe during the pandemic, when lumber prices rose?
That's a brilliant example! The increase in lumber costs led to fewer homes being built as it became more expensive for firms. How does this illustrate the concept?
It shows how a rise in input prices can shift supply downwards!
Yes! Always look for real-world applications; they reinforce the concepts. Can anyone tell a key takeaway from today?
Input prices directly affect supply levels—higher costs mean less supply!

This section discusses how changes in input prices affect a firm's supply curve in a perfectly competitive market.
The section explores the impact of fluctuations in input prices, particularly wages and other production costs, on a firm's supply curve. A rise in input prices results in increased production costs and typically leads to a leftward shift in the supply curve, while a decrease in input prices allows firms to supply more at the same market price.
In a perfectly competitive market, a firm's supply decisions are crucially influenced by the prices of inputs used in the production process. When input prices increase (for instance, if wages for labor rise), the overall cost of production escalates. This escalation typically shifts the firm's marginal cost (MC) curve to the left (or upward), reflecting a decrease in the quantity supplied at any given market price. Conversely, if input prices decrease, production costs also fall, enabling firms to supply a greater quantity at the same price, consequently shifting the MC curve to the right (or downward).
