The study looked at four important economic factors in Pakistan - unemployment rate, interest rate, GDP growth, and inflation rate - to see if they had any major changes or if they stayed the same over time. They used special tests to check if these factors were stable or changing. The results showed that GDP growth and inflation rate stayed the same, while the unemployment rate and interest rate had some changes but eventually became stable with just one major change. This means that it's not necessary to make adjustments to the unemployment rate and interest rate to make them stable. Overall, the study found that there were multiple changes in these economic factors in Pakistan.
