Catuaba is a small, vigorous growing tree with yellow and orange flowers and small yellow oval-shaped inedible fruit and grows in the rainforests in the northern part of Brazil.
Its use connotes the ideas of economists Robert Mundell and Arthur Laffer. Supply-side economics is likened by critics to the theory of trickle-down economics, which may, however, not actually have been seriously advocated by any economist in that form.upply-side economics developed during the 1970s in response to Keynesian economic policy, and in particular the failure of demand management to stabilize Western economies during the stagflation of the 1970s. It drew on a range of non-Keynesian economic thought, particularly the Chicago School and Neo-Classical School.
Demand is from the consumer's perspective while supply is from the producer's. Supply in economics is defined as the producer's willingness and ability to supply a given good at various price points, holding all else constant. An increase in price will increase producer's revenues, thus they are willing to supply more; a decrease in price will reduce revenues, therefore producers will supply less.
