Recent Developments at the CMA: 2020-2021.

We discuss three important projects that economists at the Competition and Markets Authority have completed over the past year. First, our work on the Funerals Market Investigation provides an illustration of how demand-side problems can lead to a lack of competition, as well as demonstrating the CMA's willingness to consider price control and regulatory remedies where necessary. Second, on the merger case, we point to how our assessment dealt with uncertainty in innovative markets, the importance of preventing incumbents from acquiring start-ups, and the risks of following formalistic market definitions, especially in multi-sided platform sectors.

Brominated and fluorinated organic pollutants in the breast milk of first-time Irish mothers: is there a relationship to levels in food?

Brominated flame retardants - polybrominated diphenyl ethers (PBDEs), polybrominated biphenyls (PBBs), hexabromocyclododecane (HBCD) and others - have been measured in 11 pooled breast milk samples from 109 first-time mothers in Ireland. Additionally, the study has measured levels of polybrominated dibenzo-p-dioxins and furans (PBDD/Fs), mixed halogenated dioxins (PXCC/Fs) and biphenyls (PXBs), polychlorinated naphthalenes (PCNs) and perfluoroalkylated substances (PFAS) in these samples. The mean sum of 19 PBDEs including BDE-209 was 4.

Polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and polychlorinated biphenyls (PCBs) in breast milk of first-time Irish mothers: impact of the 2008 dioxin incident in Ireland.

The 2008 dioxin incident in Ireland resulted in elevated concentrations of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and polychlorinated biphenyls (PCBs) in Irish pork and pork products, due to the consumption of contaminated animal feed by pigs. In order to investigate any resulting impact on the Irish population, these contaminants were measured in pooled breast milk samples from 109 first-time mothers, collected in 2010. A comparison of the results with similar data from 2002 revealed generally lower concentrations of PCDD/Fs and dioxin-like PCBs in the 2010 samples, confirming the declining trend reported by many authors.

Session 1: Public health nutrition. Folic acid food fortification: the Irish experience.

Adequate intake of folic acid by women during very early pregnancy can markedly reduce risk of the development of neural-tube defects (NTD). The effectiveness of advice to women to take folic acid supplements is limited, mainly because 50% of pregnancies are unplanned. However, mandatory folic acid food fortification programmes in North America have been very successful in reducing NTD rates.
