Question 1:  The following model has been used to estimate the relationship between the wage per hour  and the levels of education and experience.

1. Report the results of the regression.
2. Comment on the effect of Education on ln(Wage).
3. Derive an expression for the Elasticity of Wage with respect to Experience. Calculate  the Elasticity for a female person with (i) 16 years of education & 10 years of experience and (ii) 10 years of education & 10 years of experience. Interpret your  results.
4. For two individuals with equal levels of Education and Experience, calculate the  difference between the wages of a female and a male Comment on the  difference.
5. Test the overall significance of the model at the 1% level (assuming all OLS  assumptions are valid).
6. Given that the correlation coefficient between Exp and Exp2 is 0.9, comment on  whether the model suffers from

Question 2: Background: Health insurance companies and governments are interested in knowing which  factors determine people’s decisions to visit doctors. A researcher has collected data on 300  individuals on the following variables:

Doctor=A dummy variable 1(if theindividual visited a doctor in a given year) and 0(otherwise)
ln =log ( Income of the indivdual 1000)
Sex=1(if the person is a Male) = 0(otherwise)
Age=Age of the person

The data is available in the EXCEL file Q2A3.xlsx. The researcher considers the following  discrete outcome model where the decision to take private insurance is related to other  variables

Undertake the following:

1. Estimate a Logit model for this data set. Report the EViews output [you don’t have to  write any equations, Rp2 etc, just report the EViews table from your estimation].
2. Comment on the effect of IncomeSex and Age on the probability of visiting a doctor  (you are not required to compute marginal effects).
3. Find the average marginal effect of lnIncome and interpret this estimate.
4. Test whether being male increases the probability of visiting a doctor.
5. Estimate a Probit model and report the EViews output [just EViews output].
6. Find the average marginal effects for ln Income from the Probit model and interpret this estimate.
7. Test the overall significance of the Logit model (write down the six steps).
8. Calculate an appropriate goodness of fit measure for the estimated Logit and Probit models and use it to choose your preferred model.
