Strong 2018 Q2 Economic Growth Unsustainable

Washington Post columnist Catherine Rampell uses Penn Wharton Budget Model’s analysis of tax reform to delve into the implications behind strong second quarter U.S. economic growth in The economy’s great. That doesn’t mean Trumponomics is.

Public Infrastructure: Avoiding the Bridge to Nowhere

This June, PWBM’s First Spring Policy Forum discussed what real world evidence has to say about public infrastructure policy. PWBM’s Jon Huntley looked at how infrastructure plans can be designed to maximize growth while Ernst & Young’s Mike Parker shared a broad picture of the impact of federal spending on infrastructure.

Recent Rise in Gas Prices Offsets Some Households’ Gains from Tax Cuts

As noted in our brief, the Tax Cuts and Jobs Act reduced the direct tax liability of individuals by an estimated $1.3 billion, before considering macroeconomic feedback effects, over the period 2018-27. This reduction was achieved through a number of provisions that changed the individual income tax structure. Table 1 presents the average tax cut received by Adjusted Gross Income (AGI) percentile in 2018. The overall median tax cut is $401, with larger cuts going to groups with larger AGI.

The Jobs and Infrastructure Plan for America’s Workers

The Jobs and Infrastructure Plan for America’s Workers
  • Senate Democrats propose spending $1,022 billion on public infrastructure over the next 10 years, financed with taxes on personal income and corporate income.

  • An additional dollar of federal aid could lead state and local governments to increase total infrastructure spending by less than that dollar since state and local governments can often qualify for the new grant money within their existing and planned infrastructure programs. Based on an extensive literature review, we estimate that infrastructure investment across all levels of government increases between $225 billion and $1,039 billion, including the $1,022 billion federal investment.

  • Depending on how much state and local governments spend on infrastructure in response to federal aid, we estimate that the plan changes GDP between -0.1 and 0.1 percent by 2032 relative to no policy change. By 2042, the plan changes GDP between -0.3 and -0.2 percent.

Senator Ted Cruz’s Proposal to Index Capital Gains to Inflation

Senator Ted Cruz (R-TX) recently introduced a bill titled the “Capital Gains Inflation Relief Act of 2018”. The proposal would let investors adjust asset cost basis for inflation, resulting in a lower tax bill upon realizing capital gains.

Senate GOP Wary of New Tax Cut Sequel

In his article “Senate GOP wary of new tax cut sequel,” Alexander Bolton described Republican reactions to the CBO scoring of the new tax bill and opinions over making the individual tax cuts permanent. He cites projections from Penn Wharton Budget Model (PWBM) in order to demonstrate the likely effects on the national debt from extending the individual tax cuts.

The Tax Cuts and Jobs Act: Extending Changes to Individual Taxes

The Tax Cuts and Jobs Act: Extending Changes to Individual Taxes
  • PWBM previously analyzed the effects of the tax bill passed this December. Most of that bill’s tax cuts for individuals (non-businesses) expire at year-end 2025. This brief reports the budgetary and economic effects of indefinitely extending the individual-side tax cuts.

  • By 2027, we project that debt increases between $573 billion and $736 billion. However, GDP is relatively unchanged, although slightly contracts, because this standard 10-year budget window covers only two years of tax cut extensions.

  • By 2040, we project that GDP contracts by 0.6 percent to 0.9 percent relative to current law, where the tax cuts for individuals are set to expire. Debt increases between $5.2 trillion and $6.1 trillion.

The White House's Trade Policies and the Economy

A recent CNBC article by John Harwood, Peter Navarro says Trump’s trade policies are ‘good for the market,’ but economists aren’t buying it, applies two Penn Wharton Budget Model (PWBM) studies on the effects of tax cuts by industry and the probable effects of a trade war. The author analyzes the possibility that recent administration actions increasing protectionist measures would slow economic growth.

Incentives and Corporate Tax Cuts

Justin Wolfers’ New York Times article, "How to Think About Corporate Tax Cuts" analyzes the economic effects of President Trump’s corporate tax cuts and references Kent Smetters of Penn Wharton Budget Model. While the tax bill promises to increase the incentive to invest and gives companies more cash, Smetters argues that in the short run giving more money to corporations helps the owners.

The Effect on Households of Different Methods of Financing a UBI

To evaluate the potential effects of a hypothetical $1.5 trillion Universal Basic Income (UBI) program, PWBM conducts analyses of the program under three different financing policies. Each of the three financing options has different effects on household savings, consumption, and labor decisions, which leads to significantly different effects on the aggregate economy and household welfare.

Options for Universal Basic Income: Dynamic Modeling

Options for Universal Basic Income: Dynamic Modeling
  • Public support for a Universal Basic Income (UBI) has been increasing over time, and several experiments are already underway.

  • The Roosevelt Institute recently published an analysis of a UBI proposal that would pay $6,000 per year to every adult in the United States. Roosevelt estimates that GDP would increase by up to 6.8 percent within eight years after the policy’s onset, if the policy were deficit financed.

  • We estimate the impact of the same plan on the federal budget and economy using a richer dynamic model. If deficit financed, we project that same UBI plan would increase federal debt by over 63.5 percent by 2027 and by 81.1 percent by 2032. GDP falls by 6.1 percent by 2027 and by 9.3 percent by 2032. The smaller tax base also sharply reduces Social Security revenue, by 7.1 percent by 2027 and by 10.4 percent by 2032.

The Omnibus Spending Bill of 2018

The Omnibus Spending Bill of 2018
  • Recently, President Trump signed the Omnibus Spending Bill of 2018 into law. The bill increases the level of federal discretionary spending in 2018.

  • This report projects the impact on the economy assuming that the increase to spending levels will be sustained in future years and evolve with PWBM’s demographic and macroeconomic projections.

  • By 2027, we project that debt increases by 1.6 percent and GDP falls by 0.1 percent, relative to current spending levels. By 2037, debt increases by 1.6 percent and GDP falls by 0.2 percent.

The Impact of a Trade War Could Wash Out Tax Cuts

A CNNMoney story, “Trade War Would Wipe Out Gains From Tax Cuts, Penn Analysis Says,” applies two Penn Wharton Budget Model (PWBM) studies on trade and tax cuts. Patrick Gillespie points out that two of President Trump’s policies could have opposing effects on economic growth. If the new tariffs announced by President Trump lead to an all-out trade war, gains from the tax cuts could be washed away in the short run and swamped in the long run.

The Economic Costs of a Trade War

The Economic Costs of a Trade War
  • Major U.S. trading partners have already indicated they might retaliate to new U.S. trade tariffs recently announced by President Trump. New tariffs could, therefore, lead to a “trade war.” However, game theory also suggests that U.S. trading partners could eventually respond with “trade opening,” depending on the ultimate payoffs to each party in the trading partnerships.

  • We estimate that an all-out trade war would reduce GDP by 0.9 percent by 2027 and by 5.3 percent by 2040. Wages would decline by 1.1 percent by 2027 and 4.8 percent by 2040, relative to current policy. A trade opening would have the opposite effect: GDP would increase between 0.2 to 0.7 percent by 2027 and between 1.3 to 4.0 percent by 2040. Wages would increase between 0.3 to 0.8 percent by 2027 and between 1.2 - 3.6 percent by 2040, relative to current policy.

  • The downside risk of a trade war, therefore, is larger than the upside potential from a trade opening.

The White House FY 2019 Infrastructure Plan

The White House FY 2019 Infrastructure Plan
  • President Trump recently released his updated infrastructure plan along with the Fiscal Year 2019 Budget. The plan proposes to increase federal infrastructure investment by $200 billion to provide incentives for a total new investment of $1.5 trillion in infrastructure.

  • However, based on previous experience reviewed herein, most of the grant programs contained in the infrastructure plan fail to provide strong incentives for states to invest additional money in public infrastructure. Indeed, an additional dollar of federal aid could lead state and local governments to increase infrastructure total spending by less than that dollar since state and local governments can often qualify for the new grant money within their existing infrastructure programs. We estimate that infrastructure investment across all levels of government would increase between $20 billion to $230 billion, including the $200 billion federal investment.

  • We estimate that the plan will have little to no impact on GDP.

For Teen Workers, Parents’ Education Matters

Teenage employment has declined significantly since the late 1990s. Using data from the Current Population Survey, Figure 1 shows that 63 percent of teens aged 16 to 18 worked in 1993, but that percentage fell to 41 by 2015.

A Discussion of the White House FY 2019 Budget

In a recent podcast and article “The White House Budget: What’s the Reality” by Knowledge@Wharton, the latest budget proposal by the White House was discussed by Kent Smetters (Wharton), Alan Auerbach (UC Berkeley), and David Kamin (NYU).

Education and Income Growth

In the New York Times article “Why Is It So Hard for Democracy to Deal with Inequality?” Thomas B. Edsall relates the growth of income inequality in democracies to changes in voting patterns among those who are highly educated.

PWBM’s brief, “Education and Income Growth” was used to highlight that the incomes of highly educated people are growing in comparison to those with less education. The author finds that this trend motivates highly educated voters to support the continuation of current policy rather than policy reforms favorable to the working class.

Will federal dollars for infrastructure boost the economy?

The news blasts about America’s crumbling infrastructure are hard to miss. Data available at USAFacts shows that in 2015, 14 percent of America’s bridges were functionally obsolete and another 10 percent were structurally deficient. Meanwhile, in 2014, commuters spent an extra 42 hours stuck in traffic. 

The White House proposes to spend $200 in new federal money that it hopes will subsidize an addition $1.3 trillion in new infrastructure spending by state and local government and private enterprises.

But will those dollars achieve a high speed economy with higher wages and GDP? Our new report, Options for Infrastructure Investment: Dynamic Analysis, finds that it depends.

Options for Infrastructure Investment: Dynamic Modeling

 Options for Infrastructure Investment: Dynamic Modeling
  • President Trump proposes to increase infrastructure investment by $1.5 trillion over 10 years by attaching incentives to $200 billion of new federal spending. However, this plan lacks details about implementation. We, therefore, consider three possible options.

  • By 2027, we estimate that GDP is between 0.0 and 0.5 percent larger than under current law, depending on which one of the three policy options is used. By 2037, GDP is between 0.0 and 0.4 percent higher.

  • By 2027, debt held by the public is between 0.4 and 0.9 percent larger than under current law. By 2037, debt is between 0.4 percent lower and 0.6 percent larger.
