This study has three main objectives. First, it attempts to investigate the labor supply at the extensive margin for a second job, which is represented by the worker's decision to hold a second job. Second, the paper aimed to analyze second-job labor supply at the intensive margin, which is approximated by the hours spent in the second job. Third, the research aimed to investigate workers who have been self-employed in the second job while controlling for sample selection. The paper used the variable moon, representing all employed individuals aged between 18 and 65 who hold two jobs, as the dependent variable. Additionally, the independent variables used include individual demographic characteristics and work-related characteristics of the primary job. Quantitative research was employed, and data sources were drawn from the British Household Panel Survey (BHPS) from 1990 to 2008. The data were analyzed using STATA. The research findings confirmed the probability of having a second job at the extensive and intensive margins among the observed individuals. Furthermore, substantial evidence suggests the likelihood of individuals spending hours in a second job.
