When America’s Fiscal Crisis Hits, Be Forewarned that Tax Increases Will Make a Bad Situation Worse
At some point in the next 10 years, there will be a huge fight in the United States over fiscal policy. This battle is inevitable because politicians are violating the Golden Rule of fiscal policy by allowing government spending to grow faster than the private sector (exacerbated by the recent budget deal), leading to ever-larger budget deficits.
I’m more sanguine about red ink than most people. After all, deficits and debt are merely symptoms. The real problem is excessive government spending.
But when peacetime, non-recessionary deficits climb above $1 trillion, the political pressure to adopt some sort of “austerity” package will become enormous. What’s critical to understand, however, is that not all forms of austerity are created equal.
The crowd in Washington reflexively will assert that higher taxes are necessary and desirable. People like me will respond by explaining that the real problem is entitlements and that we need structural reform of programs such as Medicaid and Medicare. Moreover, I will point out that higher taxes most likely will simply trigger and enable additional spending. And I will warn that tax increases will undermine economic performance.
Regarding that last point, three professors, led by Alberto Alesina at Harvard, have unveiled some new research looking at the economic impact of expenditure-based austerity compared to tax-based austerity.
…we started from detailed information on the consolidations implemented by 16 OECD countries between 1978 and 2014. …we group measures in just two broad categories: spending, g, and taxes, t. …We distinguish fiscal plans between those that are expenditure based (EB) and those that are tax based (TB)… Measuring the macroeconomic impact of a plan requires modelling the relationship between plans and macroeconomic variables.
Here are their econometric results.
