One-way routes complicate cooperation in migrant crises

Area of Science:

• Behavioral Economics
• International Relations
• Game Theory

Background:

• International cooperation is crucial for managing migrant crises.
• Existing research often overlooks the complexities of one-way migration and wealth disparities.

Purpose of the Study:

• To investigate the challenges of international cooperation in migrant sheltering using experimental economics.
• To analyze how factors like migration route direction and national wealth influence cooperative decisions.

Main Methods:

• An economic game, "pass the buck," was designed to simulate country leaders' decisions on sheltering migrants.
• Participants acted as leaders, deciding whether to shelter migrants or pass them to the next country in a simulated migration crisis.

Main Results:

• Leaders sheltered fewer migrants when faced with a one-way migration route compared to simultaneous arrivals.
• The introduction of a return policy, allowing the last country to send migrants back, increased sheltering by the first country.
• Wealthier countries sheltered more migrants, while poorer countries tended to pass migrants on, exacerbating inequalities.

Conclusions:

• One-way migration routes and wealth disparities significantly hinder international cooperation in migrant sheltering.
• Policy interventions, such as return mechanisms, can potentially improve cooperative outcomes.
• Findings offer insights for designing more effective international agreements for managing refugee and migrant crises.
