Why Border Enforcement Backfired

Area of Science:

• Sociology
• Political Science
• Criminology

Background:

• U.S. immigration control strategies have historically focused on border enforcement.
• A perceived threat from Latino immigration fueled a moral panic, influencing policy.
• Self-interested actors promoted border enforcement for political and material gains.

Purpose of the Study:

• To systematically analyze why U.S. border enforcement strategies have backfired.
• To examine the theoretical underpinnings of border enforcement as a policy response.
• To investigate the impact of border militarization on unauthorized migration patterns.

Main Methods:

• Theoretical analysis of policy emergence and motivations.
• Instrumental variable approach to assess causal effects.
• Examination of border outcomes and migrant behavior.

Main Results:

• Border enforcement created a self-perpetuating cycle of increased apprehensions.
• Militarization of the border became disconnected from the actual undocumented flow.
• Border militarization shifted undocumented Mexican migration from circular to settled family patterns.

Conclusions:

• Border enforcement, as implemented, proved counterproductive to immigration control.
• The policy transformed migration dynamics, leading to a larger, more dispersed undocumented population.
• The study highlights the unintended consequences of policies driven by moral panic and political opportunism.
