Peter Dunne writes – In 1994 the then Labour Opposition resolved to introduce a new top tax rate of 39 cents in the dollar. The reason for the policy was purely political, not fiscal. Labour was shedding votes to Jim Anderton’s left-wing Alliance at the time and wanted to do something symbolic to staunch the flow. […]

There can be honest and constructive debates about the size of government, such as when I cross swords with someone on the left who understands Arthur Okun’s efficiency-equity tradeoff. Another legitimate debate is about the impact of tax policy, specifically whether higher or lower tax rates have big effects or small effects. But to have […]

I wrote a column about taxes and growth in 2020. Let’s augment that analysis by digging into some details. I decided to address the issue today after seeing a tweet with this helpful summary of how different taxes cause different levels of economic damage (the Tax Foundation also has a table that ranks different taxes, […]

There are several visual ways of helping people understand how fiscal policy (and especially marginal tax rates) can change behavior. The philoso-raptor meme. The questioning worker. Supply-and-demand curves. The Wizard-of-Id parody. To augment these examples, I’ve started a series that is based on real-world examples. Part I of the series highlighted how the capital gains […]

From a big-picture economic perspective, I worry most about the damage of high tax burdens on innovation, entrepreneurship, and investment. Those are things that generate enormous benefits for society, yet also things that are very sensitive to bad tax policy (specifically high marginal tax rates and the tax code’s bias against saving and investment). Sadly, […]

Newsflash! The super-rich are mobile, and higher taxes incentivise them to move away

The super-rich are super-mobile. So, if a country decides to increase taxes on the super-rich (for example, with a wealth tax), some (but not all) of the super-rich will simply move elsewhere. This should not be a surprise to anyone. And yet, simplistic proposals to tax the super-rich are a favourite policy for some political…

Here is his comment on the paper presented here: Summary: The U.S. tax system is highly progressive. Effective tax rates increase from 2% for the bottom quintile of income to 45% for the top hundredth of one percent. But rates may be lower among those with the highest wealth. This comment starts with the “top 400” […]

The Laffer Curve Triumphs Again: Class Warfare in the United Kingdom Backfires

The Laffer Curve provides incredibly important insights about tax policy. Most important, it informs us that you don’t measure the revenue impact of tax policy changes merely by looking at what is happening to tax rates. You also have to consider whether changes in tax rates will alter incentives to earn and report income. Or, […]

Back in 2013, I debated Joe Biden’s top economist on the death tax. Everything I said then (and wrote four years before then) is still true today. In the interview, I mentioned nations that have abolished their death taxes, including Australia. I should have mentioned Sweden as well. As a general rule, I don’t want […]

From the Journal of Public Economics Twitter feed: What happened when Spain brought back the Wealth Tax in 2011? Using variation in exposure, this paper finds: – No drop in savings, but drop in taxable wealth—mainly via legal avoidance – Asset shifting caused most revenue loss – Estimated revenue loss was 2.75x initial 2011 rev.

After the discussion in my post yesterday on the Investment Boost subsidy scheme announced in the Budget I thought a bit more about who was likely to benefit the most from it. The general answer of course is the purchasers of the longest-lived assets. Why? Because if you have an asset which IRD estimates to […]

On two separate themes; aggregate fiscal policy, and the Investment Boost initiative. Aggregate fiscal policy Over the weekend for some reason I was prompted to look up the Budget Responsibility Rules that Labour and the Greens committed to in early 2017 (my commentary on them here). At the time, the intention seemed to be to […]

I’m currently in Finland for meetings with various people and I learned that the country’s bloated public sector and expensive welfare state are imposing a very heavy cost on the economy. How heavy of a cost? According to IMF data, there’s been no growth in per-capita GDP over the past 18 years. Why is Finland […]

Ireland: Good Corporate Tax Policy vs. Bad Government Spending Policy

I’m a big fan of Ireland’s low corporate tax rate for three reasons. First, it shows that good tax policy generates positive economic outcomes as per-capita GDP in Ireland has grown by record amounts. Second, it shows that lower tax rates can in some cases lead to more revenue. Sort of a turbo-charged version of […]

Other than Art Laffer, I think of myself as the world’s biggest advocate of the Laffer Curve. I’ve literally written hundreds of columns explaining and promoting the concept. My goal is to help people understand that there is not a linear relationship between tax rates and tax revenue. Why is this the case? Because when […]
