When Finnish policymakers cut taxes on alcohol and made importing alcohol easier, rates of abortion, pre-term birth, and low birthweight all rose, according to a new study published in the scientific journal Addiction. Expanding the supply of cheap alcohol was followed by these pregnancy outcomes mainly among low-income women. Both abortions and adverse birth outcomes reverted to their previous levels after several months.
The short-term increase of adverse birth outcomes and abortions after the price cut implies that the price cut was followed by a period of increased drinking, after which the women at risk returned to the initial levels or patterns of consumption.
A plausible explanation for these findings is that when alcohol becomes more affordable to people with monetary constraints, they drink more. A population-level rise in drinking would cause a rise in prenatal exposure to alcohol and a corresponding rise in adverse birth outcomes. Another plausible explanation is that lower alcohol prices may increase unintentional pregnancies, causing a corresponding rise in abortions.
The study looked at 32,400 abortions and almost 170,000 live births over the two years before and one year after a tax cut that lowered the price of off-premises alcohol by 33%. Lowered alcohol prices were associated with a 0.84 percentage point increase in abortions immediately after the price cut. Furthermore, there was a 1.5 percentage point higher probability of low birth weight, and a 1.98 percentage point increased probability of preterm birth among low-income women after the price cut.

Addiction is a monthly international scientific journal publishing peer-reviewed research reports on alcohol, substances, tobacco, and gambling as well as editorials and other debate pieces. Owned by the Society for the Study of Addiction, it has been in continuous publication since 1884.
The Academy of Finland funds high-quality scientific research, provides expertise in science and science policy, and strengthens the position of science and research in society. The Academy works to contribute to the renewal, diversification and increasing internationalisation of Finnish research. We support and facilitate researcher training and research careers, internationalisation and the utilisation of research results. Our activities cover the full spectrum of scientific disciplines. In 2023, the Academy of Finland’s funding for research amounts to 505 million euros. The Academy is a government agency within the administrative branch of the Finnish Ministry of Education, Science and Culture.
About the ERC
The ERC, set up by the European Union in 2007, is the premier European funding organisation for excellent frontier research. It funds creative researchers of any nationality and age, to run projects based across Europe. The ERC offers four core grant schemes: Starting Grants, Consolidator Grants, Advanced Grants and Synergy Grants. With its additional Proof of Concept Grant scheme, the ERC helps grantees to bridge the gap between their pioneering research and early phases of its commercialisation. The ERC is led by an independent governing body, the Scientific Council. Since 1 November 2021, Maria Leptin is the new President of the ERC. The overall ERC budget from 2021 to 2027 is more than €16 billion, as part of the Horizon Europe programme, under the responsibility of the European Commissioner for Innovation, Research, Culture, Education and Youth, Mariya Gabriel.
