# Relationship between input price and supply

### What factors change supply? (article) | Khan Academy

The Law of Supply is the direct relationship between price and quantity If the price of inputs increase then S will decrease, shift to the left. A demand curve or a supply curve is a relationship between two, and only two, In the example above, we saw that changes in the prices of inputs in the. In economics, supply is the amount of something that firms, producers, labourers, providers of Good's own price: The basic supply relationship is between the price of a good and the quantity supplied. Prices of related goods: For purposes of supply analysis related goods refer to goods from which inputs are derived to.

## Factors Affecting Supply

Supply curve S sub 1 represents a shift based on decreased supply. Supply curve S sub 2 represents a shift based on increased supply. Firms will profit less per car, so they are motivated to make fewer cars at a given price, decreasing the quantity supplied. Firms would profit more per car, so they would be motivated to make more cars at a given price, increasing the quantity supplied.

What about shifting up and down? Economists usually talk about supply and demand curves shifting left and right, but you could think about them shifting up and down instead if you really wanted to. In this car example, you could say that when the price of steel goes up, the car maker will need to charge more at a certain quantity to cover its costs.

The supply curve would shift upward.

### EconPort - Factors Affecting Supply

It's not wrong to think of it this way, but you'll usually hear people talking about left and right shifts. Other factors that affect supply In the example above, we saw that changes in the prices of inputs in the production process will affect the cost of production and thus the supply.

Simarly, a decrease in the price of inputs leads to an increase in supply. The Current State of Production Technology Production of a good involves taking inputs, applying a process to them, and producing an output. Well, production technology is involved in the process part.

Increases in the level of production technology can make that process more efficient. For example, imagine that you run a basic T-Shirt screen printing business out of your home.

Now lets say you decide to invest in a workshop installed with the latest production technology. With this use of technology, the operation becomes more efficient and you are able increase the supply of T-shirts. Both are derived from pigs.

Therefore, pigs would be considered a related good to Spam. In this case the relationship would be negative or inverse. If the price of pigs goes up the supply of Spam would decrease supply curve shifts left because the cost of production would have increased. A related good may also be a good that can be produced with the firm's existing factors of production.

### Supply (economics) - Wikipedia

For example, suppose that a firm produces leather belts, and that the firm's managers learn that leather pouches for smartphones are more profitable than belts.

The firm might reduce its production of belts and begin production of cell phone pouches based on this information. Finally, a change in the price of a joint product will affect supply. For example, beef products and leather are joint products.

If a company runs both a beef processing operation and a tannery an increase in the price of steaks would mean that more cattle are processed which would increase the supply of leather.
