In light of the limits that have been placed on this answer I will only focus my
comments on the demand for labor and on the other hand the supply of labor.
First the demand for labor. This is to me by far the most interesting aspect of
the course. Labor demand is derived from the firms desire to maximize profits.
This is a basic assumption of labor demand. Will the firms continually try to
make changes that will improve the profitability of the firm? We assume that yes
they will. Firms are basically price takers. Now their main decision is what
quantity of their product to produce. This is because as they hire more people
they basically increase output so the decision hire more people and the decision
to produce more are basically the same decision. The optimal output will equate
marginal revenue with marginal cost. Marginal revenue is the product price in a
purely competitive market. Marginal cost is therefore the cost to produce that
unit. MPl is the change in output of the firm. What happens when a firm decides
to produce more? They must hire more labor assuming that capital remains
constant. If a firm could continuously hire more peole and increase their MRP
then we would live in a utopian society with no unemployment and peace and
happiness everywhere. But alas we live in a world with diminishing returns and
as the firm highers more people it reaches a pont where each new person costs a
little more when compared with their output then the person hired before them. A
good example of this is digging a hole 4 feet by 8feet by 6feet . One person
would do it in about half the time that two people could do it. But three people
would not do it in one third of the time. This loss in efficiency is what I am
talking about. In fact soon you couldn’t fit all of he people into the hole
and it would be so cramped that it would atually take longer to finish the hole.
If this happened then they would have a negative marginal product of labor. So
the firm should keep hiring people until its marginal revenue product exceeds
its marginal expense. But can they get people to come to their camp? Some time
scarcity in the labor force pushes the wage ratre up and this increases the
marginal expense this will shift the employment level and reduce the amount that
the firm is willing to hire unless at the same time marginal revenue product
goes up. This will have the opposite effect and keep employment up. But under
most circumstances one of these moves more than the other and a new equilibrium
is found. What this can really be used for in my personal life is the
determination of wages. Before this class I had no idea how I would decide how
may people to hire. Now I know that if I hire two people for 10 dollars per hour
then they had better be adding at least x*$10 per hour to my company. What a
bonus it was to end up taking your class and have something that I can
immediatley put to use in the “real world”. Now I will comment on the supply
of labor. A lot of this is intuitive. I understood it without knowing why or
how. It just feels right. If the salries for all markets except one are held
constant and that markets average wage increases then we should see a rise in
the supply of people willing to be secretaries. What I find intersting about
this is that this increase in the supply of secretaries should lower the amount
of money that the employer is willing to pay. What stabilizes higer wages are
other factors. Such as the cost of training and finding new employees just to
name a couple. Sometimes the labor supply will decrese while the demand for
labor increases this will result in magnified wage increases. This is because
the firms in that market have to compete more ferociously for labor and since
demand for their product is high they are willing to pay more to attract
employees. What is interesting in my mindis that the obvious thing happens it is
to hard for all the people that left one market to come back so they stay where
they are until the cost for tranfering is lower than their perceived reward for
switching markets.
