There has been bit of a wild ride in long-term unemployment in New Zealand. Long-term unemployment – longer than one year – ranging from just over 8% of unemployment in 1986 to nearly 40% in 1992 then down to 5% in 2008. Clearly the duration of unemployment in New Zealand is highly sensitive to the business cycle unlike the case in the USA or UK.

This sensitivity of long-term unemployment to the business cycle does not bode well for the hypothesis of hysteresis where human capital depreciates the longer a jobseeker is out of employment. For this hypothesis to hold, there must be some enduring aspect of long-term unemployment rather than just going up and down with the business cycle rather noticeably.

The rival hypothesis to hysteresis is the long-term unemployed tend to be those who have a lot of trouble getting employment, which is why they end up been unemployed for a long time. Again in New Zealand, these less employable jobseekers appear to be able to find jobs quite easily when the labour market is good.
