Minister for Enterprise Micheál Martin is promising further investigation into why Irish consumers continue to pay higher prices for essential goods and services than their EU counterparts.
Mr Martin was speaking about a new Forfas report on the effects of the EU single market.
The report says that, while the single market has benefited business and trade, Irish consumers have been left with some of the highest prices in the EU.
Forfas is recommending a restructuring of the VAT regime and more grants for small and medium businesses to improve Irish competitiveness.
