Economic Sanctions: A Root Cause of Migration

The question of migration occupies a central and divisive place in US politics. Yet critical questions are rarely asked about why migrants decide to leave their homes in the first place and what role US foreign policy might play in that decision. This oversight is especially glaring when it comes to one of the most common tools of US foreign policy: broad economic sanctions.
There is overwhelming evidence (1) that migration1 is driven in large part by adverse economic conditions and (2) that sanctions can have severe, harmful economic and humanitarian consequences for civilians in targeted countries. The cases of Cuba and Venezuela demonstrate this relationship clearly: The imposition or tightening of sanctions by the US government have, in recent years, fueled economic crises that in turn have led to record migratory outflows. Addressing migration at its roots will require rethinking US sanctions policy as part of a broader research and policy agenda that considers the role of US foreign policy in fueling migratory push factors abroad.
Economic Hardship Drives Migration
The decision to emigrate — often involving leaving one’s home, family, and community to undertake a perilous journey to a new country with a different language and culture, without any guarantee of safety, accommodation, or employment — is not typically one that is taken lightly. Such a life-altering decision is rarely reducible to a single factor but is rather made in the context of multiple and interrelated push and pull factors. However, one of the most well-established sets of factors that impact migration are economic.
There is broad consensus that economic conditions in the country of origin are a major determinant of the desire to migrate. A recent review of 72 peer-reviewed, survey-based analyses of migration aspirations found an overwhelming relationship between the desire to migrate and economic factors, including perception of national economic conditions, employment opportunities, household financial situation, food security, contentment with public services, and expectations of future economic conditions.
A similar relationship holds true of realized migration. Many have hypothesized an inverted U-shaped relationship between development and migration, whereby higher GDP per capita is associated with increased migration as would-be migrants gain the means to do so, until a certain point — after which higher income is associated with decreased migration. However, recent research suggests that this U-shaped relationship, though observed in cross-sectional analyses, does not hold for a given country over time.2 Rather, the relationship is clearer: poor or deteriorating economic and humanitarian conditions cause people to migrate from developing countries while growth and stability lead people to stay home.
