Class Warfare Tax Policy Causes Portugal to Crash on the Laffer Curve, but Will Obama Learn from this Mistake?

December 31, 2012 by Dan Mitchell

Back in mid-2010, I wrote that Portugal was going to exacerbate its fiscal problems by raising taxes.

Needless to say, I was right. Not that this required any special insight. After all, no nation has ever taxed its way to prosperity.

We’re now at the end of 2012 and Portugal is still saddled with a weak economy. And the higher taxes haven’t resulted in less red ink. Indeed, according to the Economist Intelligence Unit, government debt has jumped from 93 percent of GDP in 2010 to 124 percent of GDP this year.

Why did higher taxes backfire in Portugal? For the same reasons that higher taxes have failed in Greece, Spain, Bulgaria, France, Italy, the United Kingdom, and so many other nations.

• Higher taxes undermine incentives for productive behavior, thus reducing an economy’s potential for growth. This means less economic output, which also means a smaller tax base. This Laffer Curve effect doesn’t necessarily mean less revenue, but it certainly means that tax increases rarely raise as much money as initially projected.
• Higher taxes usually are a substitute for the real solution of spending restraint (i.e., Mitchell’s Golden Rule). Politicians oftentimes refuse to reduce the burden of government spending because of an expectation of additional tax revenue. Heck, in many cases, higher taxes trigger an increase in the size and scope of the public sector.

So did Portugal learn any lessons from this failed experiment in Obamanomics?

Hardly. Indeed, the government plans to double down on this approach – even though it’s increasingly apparent that higher tax burdens won’t translate into much – if any – additional tax revenue. Here are some excerpts from a report in the Financial Times.

Lisbon plans to lift income tax revenue by more than 30 per cent, raising the effective average rate by more than a third from 9.8 to 13.2 per cent. Anyone receiving more than the minimum wage of €485 a month, including pensioners, will also pay an extraordinary tax of 3.5 per cent on their income. …the steep tax increases facing many families have made the outlook for 2013 – the third consecutive year of austerity, recession and rising unemployment – the grimmest yet. Total tax revenue has fallen considerably below target this year, forcing the government to implement additional austerity measures… The coalition will be relying on increased state revenue to account for about 80 per cent of the fiscal adjustment required in 2013 – a reversal of the original bailout plan, in which consolidation was to be achieved mainly through spending cuts.

Amazing. The government imposes huge tax hikes, which don’t generate any positive results. Yet even though “tax revenue has fallen considerably below target,” confirming that there are significant Laffer Curve issues, the government chooses to repeat the snake-oil fiscal therapy of higher taxes.

Anybody want to guess what’s going to happen? The answer, of course, is that this will further dampen incentives to generate income and comply with the government’s fiscal demands.

The latest increases have stretched the tax system to the limit, says Carlos Loureiro, a tax partner at Deloitte. “The current model is exhausted. We need to do something different,” he says. “Any further increase in tax rates is unlikely to result in increased revenue.” Income from value added tax, the government’s biggest source of tax revenue representing about 36 per cent of the total, has been falling since 2008, despite a sharp increase in the rate – the main rate is now 23 per cent. Both the government and the European Commission have acknowledged the risks of depending on increased tax revenue, which is more growth sensitive, to meet fiscal targets and contingency spending cuts amounting to 0.5 per cent of national output have prepared in case of another tax shortfall.

I almost want to laugh at the part of the excerpt which notes that tax revenue “has been falling…despite a sharp increase in the rate.”

Maybe it’s time for these fiscal pyromaniacs to realize that revenues might be falling because rates are higher. In other words, Portugal not only isn’t at the ideal point on the Laffer Curve (collecting the amount of revenue needed to finance legitimate activities of government), it may even be past the revenue-maximizing part of the curve.

To be fair, there are lots of factors that determine economic performance, so higher tax burdens are just one possible explanation for why the tax base is shrinking or stagnant.

The one thing we can state with certainty, though, is that Portugal’s fiscal problem is too much government spending. The failure to address this problem then leads to very unpleasant symptoms, such as lots of red ink and self-destructive class-warfare tax policy.

If all that sounds familiar, that’s because it’s also a description of what President Obama is proposing for the United States.

Ummm…shouldn’t they be targeting politicians?

P.S. I don’t want to imply that Portugal is a total basket case. True, I’m not optimistic about the country’s future, but at least some lawmakers now acknowledge that Keynesian spending was a big mistake. And there are even signs that Portuguese officials are beginning to realize that lower tax rates should be part of the solution. But good policy may be impossible since so many people now have a moocher mentality.

P.P.S. At the risk of bearing bad news to close the year, research from both the Bank for International Settlements and the Organization for Economic Cooperation and Development shows the United States actually faces a bigger long-run fiscal challenge than Portugal.
