Trickle-down economics


Trickle-down economics, also called trickle-down theory, refers to the economic proposition that taxes on businesses and the wealthy in society should be reduced as a means to stimulate business investment in the short term and benefit society at large in the long term. In recent history, the term has been used by critics of supply-side economic policies, such as "Reaganomics". Whereas general supply-side theory favors lowering taxes overall, trickle-down theory more specifically targets taxes on the upper end of the economic spectrum.
The term "trickle-down" originated as a joke by humorist Will Rogers and today is often used to criticize economic policies that favor the wealthy or privileged while being framed as good for the average citizen. David Stockman, who as Ronald Reagan's budget director championed Reagan's tax cuts at first, later became critical of them and told journalist William Greider that "supply-side economics" is the trickle-down idea:
Political opponents of the Reagan administration soon seized on this language in an effort to brand the administration as caring only about the wealthy. Some studies suggest a link between trickle-down economics and reduced growth. Trickle-down economics has been widely criticized, particularly by left-wing, centre-left and moderate politicians and economists, but also some right-wing politicians.
A 2019 study in the Journal of Political Economy found, contrary to trickle-down theory, that "the positive relationship between tax cuts and employment growth is largely driven by tax cuts for lower-income groups and that the effect of tax cuts for the top 10 percent on employment growth is small."

History and usage

In 1896, Democratic presidential candidate William Jennings Bryan described the concept using the metaphor of a "leak" in his
Humorist Will Rogers jokingly advised in a column in 1932:
This election was lost four and six years ago, not this year. They didn’t start thinking of the old common fellow till just as they started out on the election tour. The money was all appropriated for the top in the hopes that it would trickle down to the needy. Mr. Hoover was an engineer. He knew that water trickles down. Put it uphill and let it go and it will reach the driest little spot. But he didn’t know that money trickled up. Give it to the people at the bottom and the people at the top will have it before night, anyhow. But it will at least have passed through the poor fellow's hands. They saved the big banks, but the little ones went up the flue.

William J. Bennett wrote:
Humorist Will Rogers referred to the theory that cutting taxes for higher earners and businesses was a "trickle-down" policy, a term that has stuck over the years.

Presidential speechwriter Samuel Rosenman wrote:
The philosophy that had prevailed in Washington since 1921, that the object of government was to provide prosperity for those who lived and worked at the top of the economic pyramid, in the belief that prosperity would trickle down to the bottom of the heap and benefit all.

The Merriam-Webster Dictionary notes that the first known use of "trickle-down" as an adjective meaning "relating to or working on the principle of trickle-down theory" was in 1944 while the first known use of "trickle-down theory" was in 1954.
After leaving the presidency, Democrat Lyndon B. Johnson alleged "Republicans simply don't know how to manage the economy. They're so busy operating the trickle-down theory, giving the richest corporations the biggest break, that the whole thing goes to hell in a handbasket."
Although "trickle-down" is commonly mentioned in reference to income, it has been used by economist Arthur Okun to refer to the flow of the benefits of innovation, which do not accrue entirely to the "great entrepreneurs and inventors," but trickle down to the masses. More precisely, Nobel prize economist William Nordhaus estimates that innovators are able to capture only an extremely low 2.2 percent of the total surplus from innovation. Circling back to income "trickle-down," the surplus from innovation can take the form of gains in real wages, which are spread throughout the economy, according to Nobel prize economist Paul Romer. In particular, economist William Baumol argues that "the bulk of the unprecedented and widespread rise in the developed world’s living standards since the Industrial Revolution could not have occurred without the revolution’s innovations."
Speaking on the Senate floor in 1992, Senator Hank Brown said: "Mr. President, the trickle-down theory attributed to the Republican Party has never been articulated by President Reagan and has never been articulated by President Bush and has never been advocated by either one of them. One might argue whether trickle-down makes any sense or not. To attribute to people who have advocated the opposite in policies is not only inaccurate but poisons the debate on public issues."
Economist Thomas Sowell has written extensively on trickle-down economics and loathes its characterization, citing that supply-side economics has never claimed to work in a "trickle-down" fashion. Rather, the economic theory of reducing marginal tax rates works in precisely the opposite direction: "Workers are always paid first and then profits flow upward later – if at all."

Criticisms

The economist John Kenneth Galbraith noted that "trickle-down economics" had been tried before in the United States in the 1890s under the name "horse-and-sparrow theory", writing: Galbraith claimed that the horse-and-sparrow theory was partly to blame for the Panic of 1896.
While running against Ronald Reagan for the Presidential nomination in 1980, George H. W. Bush had derided the trickle-down approach as "voodoo economics". In the 1992 presidential election, independent candidate Ross Perot also referred to trickle-down economics "political voodoo". In the same election during a presidential town hall debate, Bill Clinton said:
In New Zealand, Labour Party Member of Parliament Damien O'Connor has called trickle-down economics "the rich pissing on the poor" in the Labour Party campaign launch video for the 2011 general election.
A 2012 study by the Tax Justice Network indicates that wealth of the super-rich does not trickle down to improve the economy, but it instead tends to be amassed and sheltered in tax havens with a negative effect on the tax bases of the home economy.
In 2013, Pope Francis referred to "trickle-down theories" in his apostolic exhortation Evangelii Gaudium with the following statement :
A 2015 paper by researchers for the International Monetary Fund argues that there is no trickle-down effect as the rich get richer:
f the income share of the top 20 percent increases, then GDP growth actually declines over the medium term, suggesting that the benefits do not trickle down. In contrast, an increase in the income share of the bottom 20 percent is associated with higher GDP growth.

A 2015 report on policy by economist Pavlina R. Tcherneva described the failings of increasing economic gains of the rich without commensurate participation by the working and middle classes, referring to the problematic policies as "Reagan-style trickle-down economics," and "a trickle-down, financial-sector-driven policy regime."
In a 2016 presidential candidates debate, Hillary Clinton accused Donald Trump of supporting the "most extreme" version of trickle-down economics with his tax plan, calling it "trumped-up trickle-down" as a pun on his name.
