The supply curve when each of these determinants changes

Question

What happens to the supply curve when each of these determinants changes?

Answer 1

The following will cause an increase in supply: a decrease in resource (input) prices; improved (lower cost) technology; a decrease in business taxes, an increase in subsidies to business; a decrease in the price of another commodity. The commodity is a substitute in production if the firm was making, provided that (the firm can switch from the now lower priced one to our commodity); an expectation of lower prices in the future; and an increase in the number of sellers. It is noted change in one or more of the above will cause the increase in supply by the entire supply curve to shift to the right.  More will now at any given price be supplied. Alternatively expressed, any given amount will now be supplied at a lower price.
