From the diagram drawn identify which of the two functions represents the demand curve, supply curve and name the intercept(s) formed. Economically, it is said that equilibrium is established when the demand curve intercepts the supply curve. Hence or otherwise, determine the equilibritum price and quantity.arrow_forwardLaffer curve In the 1980s, president Reagan based his tax and spending policies on supply side eonomics. The idea behind supply side economics is the marginal tax rate is so high it discourages work. Cutting the tax rate would end up increasing tax revenue. We develop a simple model of this idea to determine the restrictions on the utility function required to generate a Laffer curve. Let T denote the tax rate, w is the real wage rate and n the labor supply. The tax revenue is T=wnT where wn is labor income, which is the tax base. For convinience assume w is constant. There is no reason for this assumption to be true, but we impose it to focus on the restrictions on the utility function to generate the Laffer curve. As the tax rate T increases, workers substitute towards leisure and away from consumption. Hence as T rises, wn falls and tax revenues falls for high enough tax rates.
