A supply side economist:
believes that the level of income and employment is determined by the level and structure of productive capacity and economic agents' choices.
does not believe that national income and employment are determined by keynesian aggregate demand.
believes that the economy must be deregulated in order to mobilise entrepreneurship and to grow.
Francois Hollande is not a supply side economist, as has been claimed by Professor Philippe Aghion, a self-declared major economic advisor: Francois Hollande is a motherhood and apple pie economist.
