Alyosha .... please don't be surprised what I don't know, I can't be the font of ALL knowledge. lol
'Productivity' is both a narrow and misleading measurement IMO; if a factory fires half its staff, and production hardly falls, Productivity of that factory will rise markedly.
Does an economy like the UK that loses a shed load of private sector workers, but then hires a shed load more public sector workers to replace them, become LESS Productive - as that is what happened.

So looking at that graph, one has to assume that productivity would start to rise, or at least the Business Investment that you are so worried about, right?
Well apparently looking at the figured released today and the report below, companies are investing, probably only slowed by the threat of a company bashing Labour government last May;

Record investment levels by firms mean that the UK economy will avoid the threat of secular stagnation. This defies warnings from some leading economists that a lack of appetite to spend among companies in advanced economies will lead to persistently slow GDP growth, according to EY ITEM Club’s special report on business investment released today.
• Business investment currently at highest level as a share of GDP since 2000
• EY ITEM Club’s forecast predicts investment by UK companies will reach a record high in 2019
• Headwinds faced in the East of England include skill shortages and infrastructure restrictions
Following a sharp decline of almost 20% during the financial crisis, business investment in the UK has performed relatively strongly since the economy emerged from recession at the end of 2009. Since 2010, investment by UK firms has more than made up for the ground lost in the recession, reaching 11% of GDP in Q2 2015,* the highest level since the end of 2000.
Looking ahead the EY ITEM Club forecasts investment by firms to rise by an average of 6.4% a year from 2015 to 2019, when it is expected to reach a record high of 12.9% of GDP. Cuts in corporation tax, low borrowing costs, increasing availability of finance, healthy corporate balance sheets, more expensive workers and last but not least, cheaper energy are all expected to contribute to this rise.
Most medium to large businesses need to plan up to 5-years ahead, and currently these figures show a record high investment expectation by 2019, but clearly one year away from ANOTHER threat of an anti business Labour government - and the probability some of those positive factors within the paragraph above would have turned business negative - could dramatically change that business investment/jobs expectations.
