If one sticks to the classical approach to business cycle dating, which considers only significant declines in economic activity as recessions, it is difficult to rationalise part of the rise in unemployment in Austria. Taking potential output into account and defining recessions as a fall in output below potential of a magnitude of at least two-thirds of the potential growth rate - a definition used by the German Council of Economic Experts - fits the picture better. However, unemployment in Austria has also been affected by labour supply effects, in particular in the early 1990s by the influx of refugees from the disintegrating Yugoslavia (which increased unemployment during an upswing) and from 2012 onwards by the opening of the labour market to new EU members (which exacerbated the rise in unemployment during a recession).
