How does Austrian Economics define Labour Productivity?

Is there a specific Austrian definition in accordance to the concept of Labour Productivity?

If Labour Productivity is too broad of a term, then I will qualify to be speaking about it in context of this video which speaks about Labour Productivity comparing Canada to the United States.

If Canada’s Labour Productivity matched that of the United States
between the years 1988 and 2008, how would our [Canadians] lives be different?

Real GDP – $8,500 higher

Personal Disposable Income – $7,500 higher

Corporate Profits – 40% higher

Federal Government Revenues – 31% higher
