Unemployment Duration Analysis: Understanding Survival and Hazard Functions
EconomyLabor and EmploymentAnalyzing the duration of unemployment until finding a job involves considering various independent variables and utilizing survival and hazard functions. These functions provide valuable insights into the percentage of individuals remaining in the sample over time and the rate of events occurring over time.
Utilizing Survival Functions
⏳Survival functions can be graphed using proc life test.
⌛The Kaplan-Meier survival function shows the percentage of individuals remaining in the sample over time.
⚠️Hazard functions can also be graphed to show the rate of events occurring over time.
Applying Exponential and Cox Proportional Hazards Models
📈The exponential model is used to analyze unemployment duration and requires the input of dependent and independent variables.
🔄The coefficients in the exponential model may produce opposite results compared to the actual data.
🔍The Cox proportional hazards model gives consistent coefficients and signs across all programs.
