Countries use sanctions to force compliance with international law or to enforce their own national interests. These measures are often seen as a comparatively mild form of pressure. The effectiveness of European and American sanctions against Russia following its attack on Ukraine has even been called into question. Empirical research shows, however, that people in sanctioned countries become significantly poorer and, on average, die earlier.
Sanctions also seem to affect migration. So far, studies have documented these effects only in individual cases, such as in Iraq or Haiti. The current analysis has now, for the first time, used statistical regression procedures to distinguish between the effects of international sanctions and other causes for migration. Comprehensive international statistics on migration and sanctions, for example, from the Organization for Economic Co-Operation and Development (OECD), form the basis of the analysis. The data set covers migration from 157 countries of origin to 32 destination countries between 1961 and 2018.
The study shows a significant increase in emigration only when sanctions go into effect. Extensive sanctions in which at least the European Union and the United States are involved lead on average to a 20-percent increase in annual emigration, according to the findings. The effects increase when sanctions begin, with emigration rates doubling in countries with long-lasting sanctions.
This is not true, however, in all sanctioned countries: "Our findings show that sanctions lead to an increase in emigration only in those countries that systematically limit political freedom of speech. Their citizens flee sanctions in larger numbers the more the government represses their voices in times of crisis,” explains Prof. Dr. Jerg Gutmann, a junior professor of behavioral law & economics at the University of Hamburg.
Researchers also looked at destination countries for sanction-driven migration and were able to show that EU sanctions lead to a significantly over-proportional increase in migration to EU member countries. “This is a possible consequence of sanctions that political decision-makers may often not be aware of,” says Prof. Dr. Matthias Neuenkirch, professor of empirical economic research at Trier University.
In addition to migration decisions on the part of those fleeing, the study also shows how governments respond to emigration caused by sanctions. For example, Cuba drastically limited emigration opportunities for medical professionals. The research team, however, could not find any evidence that these kinds of measures contribute to systematically halting migration.
