What Is the Trickle-Down Theory?

Trickle-down economics, or “trickle-down theory,” states that tax breaks and benefits for corporations and the wealthy will trickle down to everyone else. It argues for income and capital gains tax breaks or other financial benefits to large businesses, investors, and entrepreneurs to stimulate economic growth. The argument hinges on two assumptions: All members of society benefit from growth, and growth is most likely to come from those with the resources and skills to increase productive output.


Explaining Trickle-Down Theory

Understanding Trickle-Down Theory

Trickle-down economics is political, not scientific. Although it is commonly associated with supply-side economics, there is no single comprehensive economic policy identified as trickle-down economics. Any policy can be considered “trickle-down” if the following are true: First, a principal mechanism of the policy disproportionately benefits wealthy businesses and individuals in the short run. Second, the policy is designed to boost standards of living for all individuals in the long run.

The first reference to trickle-down economics came from American comedian and commentator Will Rogers, who used it to derisively describe President Herbert Hoover’s stimulus efforts during the Great Depression. More recently, opponents of President Ronald Reagan used the term to attack his income tax cuts.

Trickle-down economics comes in many forms. Supply-side theorists believe that less regulation, tax cuts for corporations, and high-income earners would incentivize companies and the wealthy to raise output and create better jobs. Demand-side theorists believe in subsidies and tariffs, whereby the wealthy need protections to keep paying their employees or to raise spending.

Steps to Trickle Down Theory

The trickle-down theory starts with a corporate income tax reduction as well as looser regulation. Also, wealthy taxpayers may get a tax cut, meaning the top income brackets get lowered. As a result, more money remains in the private sector leading to business investment such as buying new factories, upgrading technology, and equipment as well as hiring more workers. The new technologies boost productivity and economic growth.

Wealthy individuals spend more due to the extra money, which creates demand for goods in the economy and ultimately spurs economic growth and more jobs. The workers also spend and invest more, creating growth in industries such as housing, automobiles, consumer goods, and retail. Workers ultimately benefit from trickle-down economics as their standard of living increases. And since people keep more of their money (with lower tax rates), they're incentivized to work and invest.

As a result of the widespread economic growth, the government takes in more tax revenue—so much so, that the added revenue is enough to pay for the original tax cuts for the wealthy and corporations.

Key Takeaways

  • The trickle-down theory states that tax breaks and benefits for corporations, and the wealthy will trickle down to everyone else.
  • Trickle-down economics involves less regulation, tax cuts for those in high-income tax brackets as well as corporations.
  • Critics argue that the added benefits the wealthy receive adds to the growing income inequality in the country.

Trickle-Down and the Laffer Curve

American economist Arthur Laffer, an advisor to the Reagan administration, developed a bell-curve style analysis that plotted the relationship between changes in the official government tax rate and actual tax receipts. This became known as the Laffer Curve.

The nonlinear shape of the Laffer Curve suggested taxes could be too light or too onerous to produce maximum revenue; in other words, a 0 percent income tax rate and a 100 percent income tax rate each produce $0 in receipts to the government. At 0 percent, no tax can be collected; at 100 percent, there is no incentive to generate income. This should mean that specific cuts in tax rates would boost total receipts by encouraging more taxable income.

Laffer’s idea that tax cuts could boost growth and tax revenue was quickly labeled “trickle-down.” Between 1980 and 1988, the top marginal tax rate in the United States fell from 70 to 28 percent. Between 1981 and 1989, total federal receipts increased from $599 to $991 billion. The results empirically supported one of the assumptions of the Laffer Curve. However, it neither shows nor proves a correlation between a reduction in top tax rates and economic benefits to low- and medium-income earners.

Trickle down economics is akin to supply-side economics, which holds the belief that what's good for the corporate world will trickle down through the economy benefiting all. 

Criticisms of Trickle Down Theories

Trickle-down policies typically increase wealth and advantages for the already wealthy few. Although trickle-down theorists argue that putting more money in the hands of the wealthy and corporations promotes spending and free-market capitalism, ironically, it does so with government intervention. Questions arise such as, which industries receive subsidies and which ones don't? And, how much growth is directly attributable to trickle-down policies?

Critics argue that the added benefits the wealthy receive can distort the economic structure. Lower income earners don't receive a tax cut adding to the growing income inequality in the country. Many economists believe that cutting taxes for poor, and working families does more for an economy because they'll spend the money since they need the extra income. A tax cut for a corporation might go to stock buybacks while wealthy earners might save the extra income instead of spending it. Neither does much for economic growth, critics argue.

Critics also attest that any economic growth that's generated can't be tied back to the trickle-down policies. Many factors drive growth, including the Federal Reserve Bank's monetary policy such as lowering interest rates making loans cheaper. Also, trade and exports, which are sales from U.S. companies to foreign companies as well as foreign direct investment from corporations and investors overseas contribute to the economy as well.

Example of Trickle-Down Economics Today

Many Republicans use the trickle-down theory to guide their policies. But it is still very heavily debated even today. President Donald Trump signed into law the "Tax Cuts and Jobs Act" on Dec. 22., 2017. The law cut personal tax rates slightly but also personal exemptions. The personal tax cuts expire, however, in 2025 and revert to the old, higher rates. Corporations, on the other hand, got a permanent tax cut to 21%. The bill also increased the exemption for the estate tax to $11.2 million from $5.6 million, meaning the tax doesn't kick in until over $11.2 million.

Critics of the plan say the top 1 percent get the larger tax cut versus those in lower income brackets. Other critics say any economic growth from the proposal would not offset any loss of revenue from the cuts. However, supporters say that the bill will lead to more business investment, consumer spending, and economic stability for the next several years. One thing is for certain, the debate over the effectiveness of trickle-down economic theories will rage on for many years to come.
