To be considered “employed” you only need to have a job (no distinction between full time or part time)To be considered “unemployed”, you must have looked for work over the last 30 days. Otherwise, you are “not participating”.

Alternate Measures of Unemployment in the U.S.

Discouraged Workers

• Persons who are not in the labor force

• Want to and are available to work

• Have looked for work over the year, but not over the last 4 weeks

• Specific reason cited for not looking for work is that they don’t believe there is a job available

Marginally Attached Workers

• Persons who are not in the labor force

• Want to and are available to work

• Have looked for work over the year, but not over the last 4 weeks

• Any reason cited for lack of job search

Part Time for Economic Reasons

• Working less than 35 hours per week

• Want to and are available to work full time

• Gave an economic reason (Hours cut, unable to find full time work) for lack of a full time job

Let’s do a back of the envelope calculation….population grows at around 1.5% per year. Let’s assume everybody enters the workforce at 16 and retires after 45 years.

Now (2015)45 years ago

(1970)

Eligible population = 107M

1.5% x 107M = 1.60M Entering the workforce 1.60M retiring

Eligible population = 208M

1.5% x 205M = 3.12M Entering the workforce

3.12M – 1.60M = 1.52M / 12 = 126,000 per month!

Lets compare the current recession/recovery to the last few

2 years

How can the unemployment rate drop so quickly with so few jobs being created?

The primary reason for the decline in the unemployment rate over the past 6 years is the drop in labor force participation!

If we had the same participation rate today as we did in 2007, the unemployment rate would be 10.3%!

Page 14: FIN 30220: Macroeconomics Labor Markets. The US Labor Market by the numbers…* Total Population 321M “Ineligible to work” 71M Under 16 years old Inmates.

As wages fall, the marginal cost of labor for businesses drops. This allows them to profitably expand their workforces – even in the light of diminishing marginal returns to labor.

So, these perfectly competitive businesses observe a real wage and make a profit maximizing decision of how much labor to hire. Those decisions are recorded in labor demand.

Macroeconomic argument for minimum wage increase: Increasing the minimum wage would put more money into the economy, but does it?

• An increase to $10.10 would amount to a $2.85 per hour raise for those currently on minimum wage

• For a 40 hour week, that would amount to $5700 per year• If we assume that all 16 million people affected got the full $5700, that

would be an increase in income of $91.2B• $91.2B represents around .5% of the US economy

However, can this really be an increase in income?

Unless an increase in the minimum wage makes us more productive,

NO!

Microeconomic argument for increasing the minimum wage: We are creating a better distribution of income, but are we?

Case #1: Rise in minimum wage results in increased unemployment

So we have a transfer from one lower income group to another lower income group

Case #2: Rise in minimum wage creates no job loss and business can’t pass the higher costs onto consumers

Now we have a transfer from business owners to minimum wage workers

Case #3: Rise in minimum wage creates no job loss, but businesses can pass the increased cost onto consumers

Now we have a transfer from consumers to minimum wage workers
