Abstract
ABSTRACT We examine the impact of the earthquake sequence in 2010–2012 on labour productivity in New Zealand's Canterbury region, utilising a dynamic Difference-in-Differences approach and a comprehensive administrative dataset of all firms operating in New Zealand. We find a statistically significant and large positive effect on labour productivity in Christchurch City, particularly in the construction sector. This led to an observable increase in overall regional labour productivity in the Canterbury region in 2013, 2015, and 2016. In Christchurch City itself (the area most heavily impacted by the earthquakes), the positive effect lasts until 2018 and possibly later (though it is no longer statistically observable). The re-construction of the region will not continue forever, so the implications of this winding down in re-construction for labour productivity and income are potentially a matter of present and future concern.
