Incorporating Immigrant Flows into Microsimulation Models
from Social Security Bulletin, Vol. 68 No. 1 (released August 2008)
by Harriet Orcutt Duleep and Daniel J. Dowhan

Complementing the second paper's focus on forecasting immigrant earnings and emigration in a "closed system" for a given population, the last article of the trilogy explores how to project immigrant earnings for an "open system"—a system that includes future immigrants. A simple method to project future immigrants and their earnings is presented.

Research on Immigrant Earnings
from Social Security Bulletin, Vol. 68 No. 1 (released August 2008)
by Harriet Orcutt Duleep and Daniel J. Dowhan

As the first in a trio of articles devoted to incorporating immigration into policy models, this article traces the history of research on immigrant earnings. It focuses on how earnings trajectories of immigrants differ from those of U.S. natives, vary across immigrant groups, and have changed over time. The highlighted findings underscore key lessons for modeling immigrant earnings and pave the way for representing the earnings trajectories of immigrants in policy models.

Adding Immigrants to Microsimulation Models
from Social Security Bulletin, Vol. 68 No. 1 (released August 2008)
by Harriet Orcutt Duleep and Daniel J. Dowhan

Given immigration's recent resurgence as an important demographic fact in the U.S. economy, U.S. policy modelers are just beginning to grapple with how best to integrate immigrants into policy models. Building on the research reviewed in the first article of this series, this article puts forth a conceptual basis for incorporating immigration into a key type of policy model—microsimulation—with a focus on the projection of immigrant earnings.
