Minimum wage and price floors발음듣기

Voiceover: Let's think a little bit about the labor market.발음듣기

In all of these videos, whether we're talking about renting units or hiring people, these are huge oversimplifications, but we're doing it in this way so we can apply some of these basic ideas that we're being exposed to in this survey of microeconomics, so that we can apply those basic ideas to real world things.발음듣기

It's important to realize we're making huge oversimplifications and often times the real context can be more complicated or a little bit nuanced, but it gives us a way of thinking about things.발음듣기

This is the unskilled labor market, so people who don't have any specific training or experience for a given job.발음듣기

The vertical axis is their wage rate per hour.발음듣기

It's essentially the price of labor.발음듣기

This little gap here shows I started at zero, but then I jumped up to five, six, seven.발음듣기

This right here is a quantity of labor.발음듣기

We're measuring that in terms of millions of hours per month.발음듣기

Once again, we have this little gap here, so we can jump to 20 million hours, 21 million hours.발음듣기

It's important to realize, when we think about demand in the labor market, we're not talking about individual consumers, we're talking about employers.발음듣기

In most cases, demand comes from individual consumers, but now the demand is coming from employers.발음듣기

These are the people who are essentially buying labor.발음듣기

The supply is not coming from corporations.발음듣기

The supply is coming from the people who provide labor, so now it's coming from individual workers.발음듣기

Now it is coming from workers.발음듣기

Let's just say that this market starts off completely unregulated, so it has a natural equilibrium price or equilibrium wage at $6 an hour and an equilibrium quantity of labor supplied, which is 22 millions of hours per month.발음듣기

Let's say the government in this hypothetical city or country says, "You know what?발음듣기

$6 is a really low wage.발음듣기

We have trouble imagining how people live well "off of a $6 an hour wage."발음듣기

They say this right over here is too low.발음듣기

The government does not like it and maybe many of their voters are people making that wage, so they say, "Hey, you know what?발음듣기

We are going pass some well-intentioned legislation.We are going to pass a minimum wage.발음듣기

We are going to pass a law, minimum wage, that says any employer has to pay at least $7 an hour."발음듣기

$7 an hour.발음듣기

It has to be at least $7 an hour, so this right over here is a price floor.발음듣기

This is a minimum price in the market.발음듣기

When we talked about rent control, that was a price ceiling.발음듣기

That was a maximum price for rent, now this is a minimum price for labor.발음듣기

Since the price floor, this minimum price, is higher than the actual clearing price, it's going to distort the market.발음듣기

Our price floor is right over here, $7.발음듣기

This right over here is our minimum wage.발음듣기

What's going to happen here?발음듣기

If you look at the demand side of things, the employers are going to say, "Wow!발음듣기

If I have to pay $7 an hour now, I can only afford 21 million hours of labor."발음듣기

They're going to say, "I can only afford now 21 million hours of labor," but if you look at the workers they're going to say, "Gee, if I can make $7 an hour, more people are going to be willing to work."발음듣기

Either an individual might say, "If I was working 40 hours a week making $6 an hour.발음듣기

If I'm making $7 an hour, I'm willing to work 45 hours a week."발음듣기

Or there might be a student who's on the fence, who says, "Wow!발음듣기

Now wages have gone up enough that it makes sense for me to work."발음듣기

There might be someone who's retired and now, at $6 wasn't enough for them to come out of retirement, but $7 is.발음듣기

Maybe a stay at home parent now says $7 is enough for them to come out of retirement or not stay at home anymore.발음듣기

The labor, the quantity supplied of labor, in terms of hours, will increase.발음듣기

At $7 an hour, people will be willing to supply that much labor, but what's going to happen in this situation right over here?발음듣기

In this situation you have all of these people who want to work, but there's only demand for this much work.발음듣기

Right here, this is going to be an oversupply of labor.발음듣기

Another way to think about it, there's only jobs for 21 million people now and now 23 million people want to work.발음듣기

You're going to have 2 million people who are, by the classical definition of unemployed, people who are looking for work who can't find work now.발음듣기

Once again, this is completely oversimplified, because at this point right over here, based on the way I just viewed that, you would have no unemployment and we all know even when the economy is humming maximumly and there's no regulation,발음듣기

there is some unemployment, just due to frictions in the market, people just randomly quitting jobs or looking for a new job, so you could almost view this as excess unemployment.발음듣기

Or you could view this as just a very oversimplified model and in the ideal world you'd get close to zero unemployment.발음듣기

Now you have more people looking for jobs, because the wages have gone, but fewer jobs, because the employers are forced to pay more.발음듣기

If we make all of these assumptions in the model and you just want to say how many fewer jobs are there, because this, obviously, we're talking about more people even looking for jobs because the perceived wages have gone up.발음듣기

In the absolute level, based on these linear supply and demand curves, before there was demand for 22 million jobs and that was what the quantity demanded was and that's also where the quantity supplied was, but now its only 21 million.발음듣기

Based on this model, you're going to have 1 million fewer jobs.발음듣기

When you think about it in terms of surplus.발음듣기

Before the minimum wage, the entire surplus was this entire area over here.발음듣기

This entire area that's below the demand curve and above the supply curve.발음듣기

This entire area was the total surplus and it was being divided between the consumer surplus and the producer surplus.발음듣기

This right over here, between the price and the supply curve was the producer surplus.발음듣기

The producer surplus, remember the producers of labor are the individual workers.발음듣기

This was the benefit above and beyond the opportunity cost that the workers were getting was this area right over here that I'm doing in dark white or filled in white and the consumer surplus or the employer surplus here was the value that the employers were getting above and beyond the price that they had to pay.발음듣기

Now, in this situation of a minimum wage, now this is the set price, this is the quantity of labor that is demanded.발음듣기

What you lose now, the surplus that we lose is this quantity right over here.발음듣기

We could figure out that area quite easily.발음듣기

Let's see, this height right over here is 1 million hours per month, so it's going to be 1 million.발음듣기

I'll just write 1, we'll just remember it's on millions.발음듣기

Times this height right over here, which is $2 per hour.발음듣기

Times one half.발음듣기

If we just multiply these, we get this whole rectangle for the area of the triangle, we multiply it times one half.발음듣기

That gives us exactly 1 and the units are dollars per hour times millions of hours per month, gives us millions of dollars per month.발음듣기

It becomes $1 million per month of surplus, of benefit above and beyond, of total benefit that is lost to this market because of this regulation, if you assume all of the things in this model.발음듣기

Just like we talked about in the last video, we have a $1 million per month dead weight loss.발음듣기

Now, not everyone loses here.발음듣기

Because the price is set up over here, for the people who are working those first 21 million hours per month, their producer surplus has now increased, because the space between what they're getting and their opportunity cost has now increased.발음듣기

For those lucky enough to actually have a job, those workers now do have a higher surplus, but for those employers, which is on the demand side right now, who are employing those first 21 million hours of labor, they now have a smaller consumer surplus or demand surplus or employer surplus right there.발음듣기

For the first 21 million units of labor, it's redistributing the pie between the employers and the workers, but then because you are making the wage higher, it's reducing the overall demand, so there is, if you believe this model, some job destruction taking place.발음듣기
