Reaganomics remains the reference point in modern arguments over whether cutting taxes on high earners and businesses boosts growth broadly or mainly benefits those at the top.
It's the nickname for Ronald Reagan's economic plan: lower taxes, fewer regulations and a focus on bringing down inflation, with the goal of speeding up growth.
The combination of tax cuts and higher defense spending under Reagan helped nearly triple the federal debt in the 1980s, framing ongoing debates about deficits.
Inflation fell sharply and GDP grew about 3.5% a year on average, but economists disagree on how much credit belongs to tax policy versus Federal Reserve interest-rate decisions.
The top income tax rate was cut from 70% to 28% over Reagan's two terms, with supporters arguing lower rates increase the incentive to work, save and invest.
The administration eased federal regulation in sectors such as energy and finance and sought to slow the growth of non-defense domestic spending.
Reaganomics worked alongside Federal Reserve Chair Paul Volcker's high interest rates, which were aimed at breaking the double-digit inflation of the late 1970s.
