Mass deportations would reduce US labor and GDP

Speaking at a PIIE event on presidential candidate Donald Trump's immigration proposals, Warwick J. McKibben said massive deportation of unauthorized workers would sharply reduce labor supply in mining, agriculture, services, and manufacturing of durable and nondurable goods. Employing a sophisticated "G-Cubed Model" to project the economic impact of two scenarios, McKibben concluded that such deportations would reduce real GDP by 12 percent if 7.5 million workers were deported and by 2.1 percent if 1.3 million were deported. Both scenarios would ignite serious inflation.
