Integrated longitudinal employer-employee data for the United States

The development of a database infrastructure that captures the complex interactions among households and businesses at the microeconomic level and characterizes the dynamics of the modern economy is critical for the social sciences. The creation of such an infrastructure has posed a major challenge to national statistical institutes.
