Dr. Frank Walsh:

It is fair to say that one weakness in the research record of the commission is around the impact on business. The reason is one we have pointed out every year. It is in this year's report, and it was in the report on the Living Wage Commission, and what we have pointed out in detail is the need for firm level data. We have no data on that. There are very limited data in the earnings, hours and employment costs survey, EHECS, where people were asked about the proportion of workers. We have certainly utilised that data to look at what share of costs there is. However, we do not have a lot of detailed data to do anything other than look at the international literature, and based maybe on international evidence and the composition of sectors, to try to speculate about what might be an effective policy. That is the kind of work we will try to do.
