Optimal tax the optimum. Stipulating this condition results in the following formula for the optimal top tax rate, if incomes are Pareto distributed: formula_1 where: Empirical estimation of the parameters of this equation suggests that the revenue-maximising top tax rate is between approximately 50% and 80%, although this estimate neglects long-run behavioural responses, which would imply higher elasticities and a lower optimal tax rate. Saez's analysis can also be generalised to tax rates other than the top rate. In the late 1970s, Arthur Laffer developed the Laffer curve, which demonstrates that there are two effects of changing tax rates: an arithmetic effect—if
John Brooks (writer) II and the ill-fated introduction of the most famous failed automotive gambit in history, the Edsel. Brooks also wrote widely on other subjects as well, including the government-guaranteed loans to Chrysler Corporation, the public television show "Wall Street Week" and its creator Louis Rukeyser, an examination of supply-side economics, the banking behemoth Citibank, economist Arthur Laffer and his Laffer curve, the development of New Jersey's Meadowlands, New York City urban planner Robert Moses, and even the Southern grocery store chain Piggly Wiggly. Brooks's writing on finance won him three Gerald Loeb Awards, and moved Harvard economist John Kenneth Galbraith to
