Supply-side economics
Supply-side economics is a macroeconomic theory[1][2] that argues economic growth can be most effectively created by investing in capital and by lowering barriers on the production of goods and services. It was started by economist Robert Mundell during the Ronald Reagan administration. According to supply-side economics, consumers will then benefit from a greater supply of goods and services at lower prices; furthermore, the investment and expansion of businesses will increase the demand for employees and therefore create jobs. Typical policy recommendations of supply-side economists are lower marginal tax rates and less government regulation.[3]
The Laffer curve is one of the main theoretical constructs of supply-side economics.[4] It is the idea that lowering tax rates may generate more government revenue than would otherwise be expected at the lower tax rate because moving off of a prohibitively high tax system could generate more economic activity, which would lead to increased opportunities for tax revenues. Economists are divided on whether lowering tax rates is a viable model, and critics typically charge either that there has never been a time when a tax-rate cut caused economic growth or that "now" is not such a time.
The term supply-side economics was thought, for some time, to have been coined by journalist Jude Wanniski in 1975, but according to Robert D. Atkinson's Supply-Side Follies,[5] the term "supply side" ("supply-side fiscalists") was first used by Herbert Stein, a former economic adviser to President Nixon, in 1976, and only later that year was this term repeated by Jude Wanniski. Its use connotes the ideas of economists Robert Mundell and Arthur Laffer. Others prefer the term trickle-down economics.
Historical origins
Supply-side economics developed during the 1970s in response to Keynesian economic policy, and in particular the failure of demand management to stabilize Western economies during the stagflation of the 1970s.[6] It drew on a range of non-Keynesian economic thought, particularly the Chicago School and New Classical School.[7][8] Bruce Bartlett, an advocate of supply-side economics, traced the school of thought's intellectual descent from the philosophers Ibn Khaldun and David Hume, satirist Jonathan Swift, political economist Adam Smith, and even United States 'Founding Father' Alexander Hamilton.[9]
However, what most separates supply-side economics as a modern phenomenon is its argument in favor of a low tax rate for primarily collective and notably working-class reasons, rather than traditional ideological ones. Classical Liberals opposed taxes because they opposed government, taxation being the latter's most obvious form. Their claim was that each man had a right to himself and his property and therefore taxation was immoral and of questionable legal grounding.[10] Supply-side economists, on the other hand, argued that the alleged collective benefit (i.e. increased economic output and efficiency) provided the main impetus for tax cuts.
As in classical economics, supply-side economics proposed that production or supply is the key to economic prosperity and that consumption or demand is merely a secondary consequence. Early on, this idea had been summarized in Say's Law of economics, which states: "A product is no sooner created, than it, from that instant, affords a market for other products to the full extent of its own value." John Maynard Keynes, the founder of Keynesianism, summarized Say's Law as "supply creates its own demand." He turned Say's Law on its head in the 1930s by declaring that demand creates its own supply.[11]
In 1978, Jude Wanniski published The Way the World Works, in which he laid out the central thesis of supply-side economics and detailed the failure of high tax rate progressive income tax systems and U.S. monetary policy under Nixon in the 1970s. Wanniski advocated lower tax rates and a return to some kind of gold standard, similar to the 1944–1971 Bretton Woods System that Nixon abandoned.
In 1983, economist Victor Canto, a disciple of Arthur Laffer, published The Foundations of Supply-Side Economics.[12] This theory focuses on the effects of marginal tax rates on the incentive to work and save, which affect the growth of the "supply side" or what Keynesians call potential output. While the latter focus on changes in the rate of supply-side growth in the long run, the "new" supply-siders often promised short-term results.
Laffer curve
The Laffer curve embodies a postulate of supply-side economics: that tax rates and tax revenues are distinct, with government tax revenues the same (nil) at 100% tax rates as they are at 0% tax rates and with a tax rate at which maximal revenue is generated somewhere in between these two values. Supply-siders argued that in a high tax rate environment, lowering tax rates would result in either increased revenues or smaller revenue losses than one would expect relying only on static estimates of the previous tax base.[13][14]
This led the supply-siders to advocate large reductions in marginal income and capital gains tax rates to encourage allocation of assets to investment, which would produce more supply. Jude Wanniski and many others advocate a zero capital gains rate.[15][16] The increased aggregate supply would result in increased aggregate demand, hence the term "Supply-Side Economics".
Fiscal policy theory
Supply-side economics holds that increased taxation steadily reduces economic trade between economic participants within a nation and that it discourages investment. Taxes act as a type of trade barrier or tariff that causes economic participants to revert to less efficient means of satisfying their needs. As such, higher taxation leads to lower levels of specialization and lower economic efficiency. The idea is said to be illustrated by the Laffer curve. (Case & Fair, 1999: pp. 780–1).
Supply-side economists have less to say on the effects of deficits, and sometimes cite Robert Barro’s work that states that rational economic actors will buy bonds in sufficient quantities to reduce long-term interest rates.[19]
Effect on tax revenues
Many early proponents argued that the size of the economic growth would be significant enough that the increased government revenue from a faster-growing economy would be sufficient to compensate completely for the short-term costs of a tax cut, and that tax cuts could, in fact, cause overall revenue to increase.[14] Some hold this was borne out during the 1980s when, advocates of supply-side economics claim, tax cuts ultimately led to an overall increase in governmental revenue due to stronger economic growth. However, some economists dispute this assertion, pointing to the fact that revenue as a percentage of GDP declined during Reagan's term in office.[20] The fact that tax receipts as a percentage of GDP fell following the Economic Recovery Tax Act of 1981 shows a decrease in tax burden as share of GDP and a commensurate increase in the deficit, as spending did not fall relative to GDP. Total tax revenue from income tax receipts increased during Reagan's two terms, with the exception of 1982–83.[21] The Treasury Department also studied the Reagan tax cuts and concluded they significantly reduced tax revenues relative to a baseline without them.[22]
Some contemporary economists do not consider supply-side economics a tenable economic theory, with Alan Blinder calling it an "ill-fated" and perhaps "silly" school on the pages of a 2006 textbook.[23] Greg Mankiw, former chairman of President George W. Bush's Council of Economic Advisors, offered similarly sharp criticism of the school in the early editions of his introductory economics textbook.[24] Mankiw wrote in June 2017 that: "Tax cuts rarely pay for themselves. My reading of the academic literature leads me to believe that about one-third of the cost of a typical tax cut is recouped with faster economic growth."[25] In a 1992 article for the Harvard International Review, James Tobin wrote, "[The] idea that tax cuts would actually increase revenues turned out to deserve the ridicule…"[26]
The extreme promises of supply-side economics did not materialize. President Reagan argued that because of the effect depicted in the Laffer curve, the government could maintain expenditures, cut tax rates, and balance the budget. This was not the case. Government revenues fell sharply from levels that would have been realized without the tax cuts.
– Karl Case & Ray Fair, Principles of Economics (2007), p. 695.[27]
Supply side proponents Trabandt and Uhlig argue that "static scoring overestimates the revenue loss for labor and capital tax cuts",[28] and that instead "dynamic scoring" is a better predictor for the effects of tax cuts. To address these criticisms, in 2003 the Congressional Budget Office conducted a dynamic scoring analysis of tax cuts advocated by supply advocates; Two of the nine models used in the study predicted a large improvement in the deficit over the next ten years resulting from tax cuts and the other seven models did not.[29]
Effect on income inequality
Income inequality can be measured both pre- and after-tax. There is no consensus on the effects of income tax cuts on pre-tax income inequality, although one 2013 study indicated a strong correlation between how much top marginal tax rates were cut and greater pre-tax inequality across many countries.[30] However, an important side effect of income tax cuts in the U.S. is an increase in after-tax income inequality (other things equal), meaning the top earners receive a greater share of the after-tax income.[31] This is due to several tax policy factors:
- Federal income taxes are progressive, meaning that higher income tax rates are levied on higher levels of income. For example, in 2017 married couples filing jointly pay a 25% tax rate on their income between $75,900 and $153,100, but 39.6% for income above $470,700.[32] This progressive policy meant the top 1% of income earners paid roughly 45% of the income taxes despite earning 17% of the pre-tax income in 2014.[33] So cutting income tax rates means relatively less is paid by higher-income households, leaving them with a greater share of the after-tax income.[31]
- Approximately 40-50% of U.S. households do not pay federal income taxes, either because they do not earn sufficient income to pay federal income taxes or qualify for exclusions (e.g., many elderly households don't pay income taxes on their Social Security benefits). The percent of households paying income taxes by age tends to rise into the prime working years (peaking at about 80% around age 50) and falls upon retirement.[34]
- Income taxes are distinct from payroll taxes, which all workers pay. In other words, a paycheck will have withdrawal amounts for payroll taxes (e.g., Social Security and Medicare) along with withdrawals for federal income taxes; some of the latter may be refunded when the annual tax return is filed. Payroll taxes are flat taxes (the same rate is levied) for salary and wage income up to a specific threshold ($127,400 in 2017).[35]
For example, the Tax Policy Center evaluated a detailed supply-side tax cut proposal from presidential candidate Jeb Bush in 2015. Their conclusion was that the proposal would both increase deficits dramatically and worsen after-tax income inequality.[36]
The combination of market forces driving pre-tax inequality combined with a reduction in marginal tax rates after 1979 resulted in the share of after-tax income received by the top 1% increasing from 7.4% to a peak of 16.7% in 2007, before falling to 12.4% in 2013. The tax increases effective in 2013 due to the expiration of the Bush tax cuts for income over $400,000 ($450,000 for couples filing jointly) along with other tax increases on high incomes related to the Patient Protection and Affordable Care Act (Obamacare) contributed to the decline in after-tax inequality, although they were not sufficient to offset the rise in inequality since 1979.[31]
U.S. monetary and fiscal experience
Supply-side economists seek a cause and effect relationship between lowering marginal rates on capital formation and economic expansion. The supply-side history of economics since the early 1900s hinges on the following key turning points:
The 1920s
After World War I, the highest tax bracket, which was for those earning over $100,000 a year (worth at least $1 million a year now), was over 70 percent.[37] The revenue acts of 1921, 1924, and 1926, reduced this tax rate to less than 25 percent. Yet tax revenues actually went up significantly.[38]
Gene Smiley at the Foundation for Economic Education explains that:
- the share of income taxes paid by the higher net income tax classes fell as tax rates were raised. With the reduction in rates in the twenties, higher-income taxpayers reduced their sheltering of income and the number of returns and share of income taxes paid by higher-income taxpayers rose.[39]
The 1960s
Democratic president John Kennedy advocated a drastic tax-rate cut in 1963, when the top income tax rate was 91%, arguing that "tax rates are too high today and tax revenues too low, and the soundest way to raise revenues in the long run is to cut rates now."[40] The Revenue Act of 1964 emerged from Congress and was signed by Kennedy's successor Lyndon Johnson on February 26, 1964. The stated goals of the tax cuts were to raise personal incomes, increase consumption, and increase capital investments. Evidence shows that these goals were exceeded by large degree .
Reaganomics
In the United States, commentators frequently equate supply-side economics with Reaganomics. The fiscal policies of Ronald Reagan were largely based on supply-side economics.
Ronald Reagan made supply-side economics a household phrase, and promised an across-the-board reduction in income tax rates and an even larger reduction in capital gains tax rates. (Case & Fair, 1999: pp. 781–2).
During Reagan's 1980 presidential campaign, the key economic concern was double digit inflation, which Reagan described as "Too many dollars chasing too few goods", but rather than the usual dose of tight money, recession and layoffs, with their consequent loss of production and wealth, he promised a gradual and painless way to fight inflation by "producing our way out of it".[41]
Switching from an earlier monetarist policy, Federal Reserve chair Paul Volcker began a policy of tighter monetary policies such as lower money supply growth to break the inflationary psychology and squeeze inflationary expectations out of the economic system.[42] Therefore, supply-side supporters argue, "Reaganomics" was only partially based on supply-side economics.
However, under Reagan, Congress passed a plan that would slash taxes by $749 billion over five years. Critics claim that the tax cuts worsened the deficits in the budget of the United States government. Reagan supporters credit them with helping the 1980s economic expansion that eventually lowered the deficits and argued that the budget deficit would have decreased if not for massive increases in military spending.[43] As a result, Jason Hymowitz cited Reagan—along with Jack Kemp—as a great advocate for supply-side economics in politics and repeatedly praised his leadership.[44]
Critics of "Reaganomics" claim it failed to produce much of the exaggerated gains some supply-siders had promised. Krugman later summarized the situation: "When Ronald Reagan was elected, the supply-siders got a chance to try out their ideas. Unfortunately, they failed." Although he credited supply-side economics for being more successful than monetarism which he claimed "left the economy in ruins", he stated that supply-side economics produced results which fell "so far short of what it promised," describing the supply-side theory as "free lunches".[45]
Income tax revenues in constant dollars decreased by $2.77 billion in that year. FICA tax revenue increased because in 1983 FICA tax rates were increased from 6.7% to 7% and the ceiling was raised by $2,100. For the self-employed, the FICA tax rate went from 9.35% to 14%.[46] The FICA tax rate increased throughout Reagan's term, and rose to 7.51% in 1988 and the ceiling was raised by 61% through Reagan's two terms. Those tax hikes on wage earners, along with inflation, are the source of the revenue gains of the early 1980s.[47]
It has been contended by some supply-side critics that the argument to lower taxes to increase revenues was a smokescreen for "starving" the government of revenues, in the hope that the tax cuts would lead to a commensurate drop in government spending. However, this did not turn out to be the case on the spending side; Paul Samuelson called this notion "the tape worm theory—the idea that the way to get rid of a tape worm is [to] stab your patient in the stomach".[48]
Supply-side advocates like Wanniski counter that social and fiscal conservatives who supported the supply-side prescription on tax policy for this reason were misguided and did not understand the Laffer Curve.[49]
There is frequent confusion on the meaning of the term 'supply-side economics', between the related ideas of the existence of the Laffer Curve and the belief that decreasing tax rates can increase tax revenues. But many supply-side economists doubt the latter claim, while still supporting the general policy of tax cuts. Economist Gregory Mankiw used the term "fad economics" to describe the notion of tax rate cuts increasing revenue in the third edition of his Principles of Macroeconomics textbook in a section entitled "Charlatans and Cranks":
An example of fad economics occurred in 1980, when a small group of economists advised Presidential candidate, Ronald Reagan, that an across-the-board cut in income tax rates would raise tax revenue. They argued that if people could keep a higher fraction of their income, people would work harder to earn more income. Even though tax rates would be lower, income would rise by so much, they claimed, that tax revenues would rise. Almost all professional economists, including most of those who supported Reagan's proposal to cut taxes, viewed this outcome as far too optimistic. Lower tax rates might encourage people to work harder and this extra effort would offset the direct effects of lower tax rates to some extent, but there was no credible evidence that work effort would rise by enough to cause tax revenues to rise in the face of lower tax rates. … People on fad diets put their health at risk but rarely achieve the permanent weight loss they desire. Similarly, when politicians rely on the advice of charlatans and cranks, they rarely get the desirable results they anticipate. After Reagan's election, Congress passed the cut in tax rates that Reagan advocated, but the tax cut did not cause tax revenues to rise.[50][51]
When vying for the Republican party presidential nomination for the 1980 election, George H.W. Bush derided Reagan's supply-side policies as "voodoo economics". However, later he seemed to give lip service to these policies to secure the Republican nomination in 1988, and is speculated by some to have lost in his re-election bid in 1992 by allowing tax increases. (See: "Read my lips: No new taxes".)
Clinton years
The Clinton years represent a counter-example to supply side economics, as tax increases coincided with record job creation. President Clinton presided over the budgets for fiscal years 1994-2001. From 1998-2001, the budget was in surplus, the only years since 1969. Clinton signed the Omnibus Budget Reconciliation Act of 1993 into law, which raised income taxes rates on incomes above $115,000, created additional higher tax brackets for corporate income over $335,000, removed the cap on Medicare taxes, raised fuel taxes, and increased the portion of Social Security income tax subject to tax, among other tax increases. Income tax revenues roughly doubled in dollar terms, from $510B in 1993 (7.5% GDP) to $994B in 2001 (9.4% GDP).[52]
More jobs were created during the Clinton era than the Reagan era, both in numeric and percentage terms.[53] GDP growth also was higher.[54] Defense spending was held roughly flat in dollar terms, at $282B in 1994 (3.9% GDP) and ending at $306B in 2001 (2.9% GDP). Likewise, non-defense discretionary spending fell from 3.6% GDP in 1994 to 3.2% GDP in 2001. The combination of increasing tax revenues and falling spending relative to GDP moved the budget from a 2.8% GDP deficit in 1994 to a 1.2% GDP surplus in 2001.[52]
Research since 2000
In 2003, Alan Murray, who at the time was Washington bureau chief for CNBC and a co-host of the television program Capital Report, declared the debate over supply-side economics to have ended "with a whimper" after extensive modeling performed by the Congressional Budget Office (CBO) predicted that the revenue generating effects of the specific tax cuts examined would be, in his words, "relatively small."[29] Murray also suggested that Dan Crippen may have lost his chance at reappointment as head of the CBO over the dynamic scoring issue.
Before President Bush signed the 2003 tax cuts, the Economic Policy Institute (EPI) released a statement signed by ten Nobel prize laureates entitled "Economists' statement opposing the Bush tax cuts", which states that:
Passing these tax cuts will worsen the long-term budget outlook, adding to the nation’s projected chronic deficits. This fiscal deterioration will reduce the capacity of the government to finance Social Security and Medicare benefits as well as investments in schools, health, infrastructure, and basic research. Moreover, the proposed tax cuts will generate further inequalities in after-tax income.[56]
Nobel laureate economist Milton Friedman agreed the tax cuts would reduce tax revenues and result in intolerable deficits, though he supported them as a means to restrain federal spending.[57] Friedman characterized the reduced government tax revenue as "cutting their allowance".
Bush tax cuts
In 2001, President George W. Bush signed the Economic Growth and Tax Relief Reconciliation Act of 2001. Rather than wait for the start of the new fiscal year, income tax rate reductions started on July 1, 2001. In addition, rebate checks were sent to everyone who filed a 2000 income tax return before October 1, the start of the new federal fiscal year.[58] Federal revenues in FY2001 were $1.946 trillion, $79 billion lower than in FY2000. More of the 2001 tax cut took effect at the start of FY2002, including cuts in the estate tax, retirement and educational savings.[59] Federal revenues in FY2002 were $1.777 trillion, $247 billion lower than in FY2000.
In 2003, President Bush signed the Jobs and Growth Tax Relief Reconciliation Act of 2003. Income tax rates were immediately reduced and rebate checks issued (without waiting for the new fiscal year).[60] Federal revenues in FY2003 were $1.665 trillion, $360 billion lower than in FY2000. Federal revenues in FY2004 were $1.707 trillion, $318 billion lower than in FY2000. Federal revenues in FY2005 were $1,888, $137 billion lower than in FY2000, but by 2006 revenue had completely recovered (in inflation adjusted dollars), with receipts at $2.037 trillion, $12 billion higher than 2000. The cumulative total of federal revenues less than in FY2000 for the fiscal years 2001–2005 was $1.142 trillion, with that amount expected to be recovered by 2011, with 2012 expected to produce an additional $400 billion in excess revenue over 2000.
Later analysis of the Bush tax cuts by the Economic Policy Institute claims that the Bush tax cuts have failed to promote growth, as all macroeconomic growth indicators, save the housing market, were well below average for the 2001 to 2005 business cycle. These critics argue that the Bush tax cuts have done little more than deprive government of revenue, increase the deficit, and worsen after-tax income inequality.[61] Following the release of the EPI report, though, growth remained strong and newer numbers disputed the conclusions of the report. In 2007, the Bush administration pointed to the long period of sustained growth, both in GDP and in overall job numbers, as well as increases in personal income and decreases in the government deficit.[62] However, the claims by the Bush administration were made prior to the onset of the 2008 financial crisis.
In terms of deficit impact, the non-partisan Congressional Budget Office has consistently reported that the Bush tax cuts did not pay for themselves and represented a sizable decline in revenue for the Treasury relative to baselines without the cuts:
- The CBO estimated in June 2012 that the Bush tax cuts of 2001 (EGTRRA) and 2003 (JGTRRA) added approximately $1.5 trillion total to the debt over the 2002-2011 decade, excluding interest.[63]
- The CBO estimated in January 2009 that the Bush tax cuts would add approximately $3.0 trillion to the debt over the 2010-2019 decade if fully extended at all income levels, including interest.[64]
- The CBO estimated in January 2009 that extending the Bush tax cuts at all income levels over the 2011-2019 period would increase the annual deficit by an average of 1.7% GDP, reaching 2.0% GDP in 2018 and 2019.[64]
- Prior to the American Taxpayer Relief Act of 2012 (ATRA), CBO estimated that allowing the expiration of just the upper-income portion of the Bush tax cuts would raise $823 billion in revenue over the next 10 years relative to current policy, saving $950 billion (0.5 percent of GDP) when accounting for debt service. ATRA permanently extended the Bush tax cuts for households earning less than $400,000.[65]
Federal revenues include revenue from different taxes that were cut, stayed the same, or were raised. For example, the Social Security FICA tax rate stayed the same while the maximum income subject to the tax was increased each year, resulting in a tax increase for those earning more than the previous limit.[66] Social Security tax revenues increased each and every year. Including increasing tax revenues from taxes that stayed the same or were increased hides the magnitude of the revenue decrease in taxes that were cut. Income tax rates were cut and income tax revenues were lower than the FY2000 level each and every fiscal year from 2001 to 2005, a cumulative revenue decrease of $640 billion (measured in nominal dollars).
But, by 2006 revenues exceeded the 2000 level. Likewise Corporate income tax rates were cut and revenues were lower than the FY2000 level each and every fiscal year from 2001 to 2004. But, by 2005 the inflation adjusted take exceeded that of 2000 by over 20%, and by 2006 nearly 50% higher. Since tax cuts took after a stock market crash, and their effects were contemporaneous with both a recession and the 9/11 attacks, it's unclear whether temporary decreases in government revenue were the result of those cuts, or to other factors affecting the economy.
In 2006, the CBO released a study titled "A Dynamic Analysis of Permanent Extension of the President's Tax Relief."[67] This study found that under the best possible scenario, making tax cuts permanent would increase the economy "over the long run" by 0.7%. Since the "long run" is not defined, some commentators[68] have suggested that 20 years should be used, making the annual best case GDP growth equal to 0.04%. When compared with the cost of the tax cuts, the best case growth scenario is still not sufficient to pay for the tax cuts. Previous official CBO estimates had identified the tax cuts as costing the equivalent of 1.4% of the GDP in revenue. According to the study, if the best case growth scenario is applied, the tax cuts would still cost the equivalent of 1.27% of the GDP.[68]
This study was criticized by many economists, including Harvard Economics Professor Greg Mankiw, who pointed out that the CBO used a very low value for the earnings-weighted compensated labor supply elasticity of 0.14.[69] In a paper published in the Journal of Public Economics, Mankiw and Matthew Weinzierl noted that the current economics research would place an appropriate value for labor supply elasticity at around 0.5,[70] although Dr. Mankiw notes, "unfortunately, the academic literature on this topic is far from conclusive."
A 2008 working paper sponsored by the IMF showed "that the Laffer curve can arise even with very small changes in labor supply effects" but that "labor supply changes do not cause the Laffer effect."[71] This is contrary to the supply-side explanation of the Laffer curve, in which the increases in tax revenue are held to be the result of an increase in labor supply.[72] Instead their proposed mechanism for the Laffer effect was that "tax rate cuts can increase revenues by improving tax compliance." The study examined in particular the case of Russia which has comparatively high rates of tax evasion. In that case, their tax compliance model did yield significant revenue increases:
To illustrate the potential effects of tax rate cuts on tax revenues consider the example of Russia. Russia introduced a flat 13 percent personal income tax rate, replacing the three tiered, 12, 20 and 30 percent previous rates (as detailed in Ivanova, Keen and Klemm, 2005). The tax exempt income was also increased, further decreasing the tax burden. Considering social tax reforms enacted at the same time, tax rates were cut substantially for most taxpayers. However, personal income tax (PIT) revenues have increased significantly: 46 percent in nominal and 26 percent real terms during the next year. Even more interesting PIT revenues have increased from 2.4 percent to 2.9 percent of GDP—a more than 20 percent increase relative to GDP. PIT revenues continued to increase to 3.3 percent during the next year, representing a further 14 percent gain relative to GDP.[71]
In 2003, a Congressional Budget Office study was conducted to forecast whether currently proposed tax cuts would increase revenues. The study used dynamic scoring models as supply side advocates had wanted and was conducted by a supply side advocate. The majority of the models applied predicted that the proposed tax cuts would not increase revenues.[29]
Criticisms
Critics argue that the Laffer curve only measures the rate of taxation, not tax incidence, which may be a stronger predictor of whether a tax code change is stimulative or dampening.[74] In addition, some studies have shown that tax cuts done in the US in the past several decades seldom recoup revenue losses and have minimal impact on GDP growth.[75][76][77][78]
David Harper claims that some economists dismiss the theory as offering "nothing particularly new or controversial as an updated view of classical economics."[79]
In 2012, a majority of economists surveyed rejected the viewpoint that the Laffer Curve's postulation of increased tax revenue through a rate cut would apply to federal US income taxes of the time in the medium term. When asked whether a “cut in federal income tax rates in the US right now would raise taxable income enough so that the annual total tax revenue would be higher within five years than without the tax cut,” none of economists surveyed by the University of Chicago agreed. 35% agreed with the statement "a cut in federal income tax rates in the US right now would lead to higher GDP within five years than without the tax cut."[80]
Critics of supply-side policies emphasize the growing federal and current account deficits, increased income inequality and the policies' failure to promote growth.[81]
In 2006 Sebastian Mallaby of The Washington Post quoted George W. Bush, Dick Cheney, Bill Frist, Chuck Grassley, and Rick Santorum misstating the effect of the Bush Administration's tax cuts.[82] On January 3, 2007, George W. Bush wrote an article claiming "It is also a fact that our tax cuts have fueled robust economic growth and record revenues."[83] Andrew Samwick, who was Chief Economist on Bush's Council of Economic Advisers from 2003 to 2004 responded to the claim:
You are smart people. You know that the tax cuts have not fueled record revenues. You know what it takes to establish causality. You know that the first order effect of cutting taxes is to lower tax revenues. We all agree that the ultimate reduction in tax revenues can be less than this first order effect, because lower tax rates encourage greater economic activity and thus expand the tax base. No thoughtful person believes that this possible offset more than compensated for the first effect for these tax cuts. Not a single one.[84]
The Congressional Budget Office (CBO) has estimated that extending the Bush tax cuts of 2001–2003 beyond their 2010 expiration would increase deficits by $1.8 trillion over the following decade.[85] The CBO also completed a study in 2005 analyzing a hypothetical 10% income tax cut and concluded that under various scenarios there would be minimal offsets to the loss of revenue. In other words, deficits would increase by nearly the same amount as the tax cut in the first five years, with limited feedback revenue thereafter.[86]
Occasionally a politician claims that tax cuts increase government revenue (for example Mitch McConnell in July 2010[87]). However, critics have countered that the Laffer Curve reflects the hypothesis that only cutting tax rates to the right of peak economic performance rate will increase revenues, and that cutting tax rates to the left of the peak rate will decrease revenues. They therefore argue that the increase in the deficit from the tax cuts (see above paragraph) shows that the past tax rates were to the left of the peak rate.[87]
The paradigm of a tax system which rewards investment over consumption was accepted across the political spectrum, and no plan not rooted in supply-side economic theories has been advanced in the United States since 1982 (with the exception of the Clinton tax increases of 1993) which had any serious chance of passage into law. In 1986, a tax overhaul, described by Mundell as "the completion of the supply-side revolution" was drafted. It included increases in payroll taxes, decreases in top marginal rates, and increases in capital gains taxes. Combined with the mortgage interest deduction and the regressive effects of state taxation, it produces closer to a flat-tax effect. Proponents, such as Mundell and Laffer, point to the dramatic rise in the stock market as a sign that the tax overhaul was effective, although they note that the hike in capital gains may be more trouble than it was worth.
Cutting marginal tax rates can also be perceived as primarily beneficial to the wealthy, which commentators such as Paul Krugman see as politically rather than economically motivated.[88]
The specific set of foolish ideas that has laid claim to the name "supply side economics" is a crank doctrine that would have had little influence if it did not appeal to the prejudices of editors and wealthy men.[89]
The economist John Kenneth Galbraith wrote, "Mr. David Stockman has said that supply-side economics was merely a cover for the trickle-down approach to economic policy—what an older and less elegant generation called the horse-and-sparrow theory: If you feed the horse enough oats, some will pass through to the road for the sparrows."[90]
