Explanation:

In a classical model, the production function depends on the capital stock (K) and labor (L). The production function is: Y(K,L). If the capital stock and technology increases, then firms will use more this production factor than labor. This will traduce in a decrease in the demand labor. Remember firms demand labor and workers offer it.

If real wages increase too, then more people would like to work. This will increase the total labor supply.
