Macroeconomics

In macroeconomics, solving for labor and demand involves analyzing the labor market equilibrium where the quantity of labor supplied equals the quantity of labor demanded. This can be done using the labor supply curve, which typically slopes upward, and the labor demand curve, which usually slopes downward. By identifying the intersection point of these curves, you can determine the equilibrium wage and employment level. Additionally, factors like economic policies, productivity, and overall demand in the economy can influence these curves and shift the equilibrium.

Keynesian theories allow for policy changes to affect progress of the national economy through making changes to the national debt by selling or withdrawing national bonds, by printing or withdrawing money, by changing the amount of tax to be collected and by controlling the amount of reserve money that banks should hold in their vaults. When these changes are made to oppose the progress or decline of the national economy a degree of stability is thought to be provided.

The moneyists would not understand how any of these changes really affect the prrogress nor stability but instead they would claim that by making changes to the prime rate of interest on the national bonds, can a change in the policy be introduced and with it a degree of stability obtained.

It should be noted that neither kind of claim is truly effective!
