Public Policy Institute of California (PPIC) research fellows Magnus Lofstrom and Sarah Bohn, and UC Berkeley professor of public policy Steven Raphael are issuing a new report that examines whether LAWA achieved its primary aims: reducing the unauthorized population, deterring their employment opportunities and improving employment outcomes of competing authorized workers. Their analysis also investigates whether Arizona’s legislation induced a shift away from formal employment.
This discussion focuses on the MPI report, "Executive Action on Immigration: Six Ways to Make the System Work Better," which outlines administrative actions that can be implemented to improve the immigration system.

287(g) programs have surged into the public consciousness in recent years. Now operating in 72 jurisdictions, the 287(g) program authorizes state and local law enforcement officers to screen people for immigration status, issue detainers to hold unauthorized immigrants on immigration violations, and begin the process of their removal from the United States.

Holzer examines the economic reasoning and research on these questions and looks at the policy options that shape the impact of less-skilled immigration on the economy.

Seizing on reports of a migrant “caravan” making its way northward through Mexico, President Donald Trump called for up to 4,000 National Guard troops to deploy to the Southern border. Although previous presidents took similar action in response to upticks in violence and apprehensions, the picture at the border today differs on several metrics. This article examines how the deployment compares to those under Presidents George W. Bush and Barack Obama.

This discussion, featuring California's Labor Commissioner and the head of the Tennessee Bureau of Workers' Compensation, launched a report that examines state innovations in labor standards enforcement in low-wage, immigrant-dense industries. With wage underpayment, payroll fraud, and other violations widespread in industries such as construction and car-washing, the discussion focused on how targeted enforcement can deter practices that hurt native-born and immigrant workers alike, cost state tax revenue, and disadvantage law-abiding employers.
In an era of stepped-up immigration enforcement, speakers at this event present their research on the impact of enforcement policies on children from immigrant families and U.S. public schools.
Together, Canada, Mexico, and the United States are home to nearly one-quarter of the world's migrants. Despite shifts in the profile of those who migrate and changing demographic realities across the region, such as population aging, perceptions and policies remain set in earlier eras. This article explores the intersection of migration and population dynamics in North America and the Northern Triangle of Central America.
The Trump administration has been steadily building a case to penalize "sanctuary" cities—those jurisdictions that in some way limit their cooperation with federal immigration authorities—after threatening to cut federal funding. Despite court rulings that seemed to strike a blow against these efforts, the Justice Department is moving forward with its strategy, relying on a broad interpretation of a federal statute, as this article explores.
Experts explore the significance of the Trump administration’s decision not to renew Temporary Protected Status (TPS) for the approximately 263,000 Salvadorans residing in the United States, including the social impact of terminating TPS and the likely effects on the U.S. and Salvadoran economies, migration, and criminal violence, as well as policy options to address the fallout from the decision.
