This paper examines the potentiality of the Survey of Income and Program Participation (SIPP) for labor market analysis. We consider five areas of analysis: (1) labor force participation, employment, and unemployment; (2) labor market effects of income maintenance programs; (3) earnings; (4) work and retirement of the elderly; and (5) migration. We find that the SIPP is a potentially rich resource for labor market analysis, surpassing much of what is to be found in existing databases. We note some remaining problems and make recommendations for changes.
