Concepts of Unemployment

Employed Unemployed Not Looking

Population

Labor ForceLabor Force: People willing to work at market equilibrium wage, both employed and unemployedUnemployment Rate: Number of Unemployed/Labor Force

Keynesian View: Unemployment consists of excess labor supply in market economy

Classical View: The unemployed consist of those searching for jobs

Exploratory Data Analysis

Unemployment Rate is Regressed against male unemployment rate and female unemployment rate

The regression is Significant as seen by the F-stat

The variables are both equally significant in the unemployment rate as seen by their the t-stat

Therefore male and female unemployment rates are very close.

Exploratory Data Analysis

There is no significant relationship (as seen by the t-stats) between having a degree and being unemployed or having no degree and being unemployed

Intuitively this seems very wrong and can be accounted for by the constant.

In the next slide the constant will be removed

With the Constant removed both variables become significant

Small coefficients imply a very small effect on the unemployment rate

This regresses the Unemployment rate vs the Crime rate

We found that the unemployment rate is not a significant factor in the crime rate as seen by the low f-stat and the low t-stat

This regression has the Unemployment Rate vs Suicide Rate

We found that there is a slight relationship between the two

The f-stat is low, but the R2 indicates that there is some relationship between the variables

Welfare regressed against unemployment shows a significant relationship between the two

Intuitively, as the number of unemployed people grows, the greater demand for welfare

Exploratory Data Analysis

Here the Unemployment Rate is regressed against multiple variables

All variables are significantly contribute to the Unemployment Rate

Annual Inc per cap coefficient is negative, suggesting a higher income implies a lower unemployment rate

Surprisingly, as crime rate increases unemployment decreases

ConclusionRecap:

Regressing unemployment rate with these a few durations has no meanings. Unemployment rates between Men and Women have no significant difference We can compare different sample means: Unemployment rates between Men and Women have no significant

difference: Unemployment rates between Degree and No Degree have significant

difference: Regress unemployment rate with men and women unemp (with c and without

c): Regress unemployment rate with degree and no degree unemp (with c and

without c): Regress annual income with unemployment rate (not significant, no

relationship): Regress crime rate with unemployment rate (not significant, no relationship): Regress suicide rate with unemployment rate (not significant, some

relationship): Regress welfare budget with unemployment rate (significant, strong

relationship): Regressing unemployment rate with these four variables has no meanings. Regress Unemployment with Annual Income, Crime rate, Suicide rate,

Welfare budget(Significant)

Conclusions I have no money and cannot

get any work Father, can’t I have a piece of

bread I say father, could you get

some specie claws? I’m so hungry My dear, cannot you continue

to get some food for the children I don’t care for myself

I say Sam, I wonder where we are to get our Costs

**Warrant Distraint for rent**

Future Investigations Next time, I top down

approach how does state and county unemployment break down.

Page 24: Analysis of Unemployment

Future Investigations Or a bottom up

approach that considers the dynamic between US unemployment and international unemployment.
