1. Capital operating times continued to increase in 2017
The Banque de France’s productive capital operating times (COT) survey provides data on the adjustments made by businesses to respond rapidly to changes in demand without resorting to new investments. The survey was recently used by Cette, Lecat and Jiddou (2016) to study production factor (capital, labour) adjustment and use (labour working time, COT, capacity utilisation rates) and thereby examine the impact of obstacles to extending COT on this adjustment path. The authors notably show that when faced with a demand shock, businesses first adjust via their capacity utilisation rate and capital operating times, and then later adapt their labour and capital stock.
A significant rise in COT in line with industrial activity
In 2017, manufacturing firms’ capital operating times increased on average at a more elevated pace than in the previous year. In a context of growth recovery (GDP was up 1.9% in 2017 after an increase of 1.1% in 2016, according to Insee figures), COT grew on average by 3.7% in 2017, after increases of 1.6% and 1.7% in 2016 and 2014, respectively (see Chouard et al., 2017, 2016 and 2015).
Changes in COT, measured every September by the Banque de France, are linked to changes in industrial activity. Manufacturing output was more buoyant in 2017 than in 2016 (see Table 1), and this change in productive activity was accompanied by a sharper increase in COT in 2017 than in 2016, in line with the capacity utilisation rate (see Chart 1).
Although COT decreased in 2017 in agriculture and manufacture of food products, it increased in the other sectors, with a particularly steep rise in the transport equipment sector. Broken down by business size, large firms reported an average increase in COT of 4.2%, which was higher than the 3.3% increase noted by small and medium‑sized industries (SMIs, with less than 500 employees) – see Table 1 and Charts 2a and 2b.
Business leaders expect COT to rise further in 2018, by 2.7% (see Table 1), and both SMIs and large firms also expect COT to increase, by 3.7% and 1.5%, respectively. All sectors foresee an increase in 2018. To lengthen productive capital operating times and thus the use of capital stock, businesses can extend their employees’ working time, or reorganise production with several operators from a team working shifts at the same post.
