Today I’ve been following a document trail concerning the French government decision to adopt the so-called Barre Plan in 1976. This is part of the research on doing for my next book on why the Left abandoned progressive economic strategies and became what we now think of as austerity-lite merchants. I am hoping the manuscript will be finished by April 2016 and the book will emerge a bit later in the year. while the approach that will be taking is emerging, the strategy is to pinpoint key events in history where significant economic policy changes occurred and to analyse the rationale that was used to defend those policy shifts and to assess whether the circumstances that applied at those points in time provide any guidance to current day challenges. One of the big events that lead to deep uncertainty among Social Democratic politicians and their advisers, which arguably, was a key driver in the shift of these parties to the Right, was the Stagflation of the 1970s. The phenomenon of the simultaneous coincidence of accelerating inflation and rising unemployment had not previously been witnessed in the period following the Second World War. It needs a careful analysis because much of the popular understanding of this period and the claims that it demonstrated a failure of Keynesian policy approaches are incorrect and provide no basis for rejecting fiscal intervention to maintain full employment.
