Because of the importance of labor productivity in explaining economic growth, the economic growth model focuses on the causes of increases in long-run labor productivity. A If you look up the IS-LM model in different text books you will probably see different models but the main predictions from the models do tend to be the same. If the number of hours worked increases, the unemployment will fall and vice versa.
