Estimation of FGT poverty indices

 

How poor was Burkina Faso in 1994?

 

  1. Open the bkf94.dta file and label variables and values using the do file lab_bkf94.do.  Type the describe command and then label list to list labels.

  2. Set the sampling design and then save the file (use variables strata, psu, and weight)
  3. Estimate the headcount index using variables of interest expcc and expeq.

    1. You should set Size to household size in order to estimate poverty over the population of individuals.

    2. Use the so-called 1994 official poverty line of 41099 Francs CFA per year.

  4. Estimate the headcount index using the same procedure as above except that the poverty line is now set to 60% of the median.

  5. Using the official poverty line, how does the headcount index for male- and female-headed households compare?

  6. Can you draw a 99% confidence interval around the previous comparison? Also, set the number of decimals to 4.

 

Answer

 

Q.1

 

If bkf94.dta is saved in the directory c:/data, type the following command to open it:

use "C:\data\bkf94.dta", clear

 

If lab_bkf94.do is saved in the directory c:/do_files, type the following command to label variables and labels:

 

do "C:\do_files\lab_bkf94.do"

 

Typing the command describe, we obtain:

 

obs:        8,625                      

vars:       9                             31 Oct 2006 13:48

size:       285,087 (99.6% of              memory free)
