Do we need a global tax to stop rising inequality (crosspost from Crooked Timber seminar on Piketty)

John Quiggin33 Comments

One of the more depressing features of Capital in the 21st Century is the air of inevitability attached to the much-discussed r > g inequality. This is exacerbated, on the whole, by the fact that Piketty’s proposed policy response, a progressive global tax on wealth, seems obviously utopian.

What about a much simpler alternative: increasing the rate of income tax applied to the very rich, and removing preferential treatment of capital income? Piketty’s own work with Saez yields the conclusion that the socially optimal top marginal rate of taxation, after taking account of incentive effects, would be 70 per cent or more. Such rates prevailed, at least nominally, in the mid-20th century, without obvious ill effects. Again, Piketty provides the relevant evidence.

So, is there something about a globalised world economy that renders a return to high marginal rates of taxation impossible?

Bracket creep: How to get the answer you want

John Quiggin18 Comments

NATSEM recently released modelling showing that discretionary tax cuts have more than offset bracket creep since 2005 (that is, taxes are lower than if the income tax scales had been indexed to the CPI or a wage index). The Centre for Independent Studies replied with a study pointing out that you get the opposite conclusion by looking at the period since 2013. Why 2013?

We chose 2013 as the starting year because this is when the last change to tax thresholds occurred

Well, yes. If you pick a period in which there have been no discretionary tax cuts, you will certainly find that discretionary tax cuts have not outweighed bracket creep. As author Michael Potter observes

This shows the importance of the starting year.

There’s no need to check the CIS numbers: given the setup, only one answer is possible.

Correction Michael Potter advises that the CIS study includes the impact of the tax changes in 2012-13, making it possible in principle that these could have offset bracket creep. But the 2012-13 changes weren’t a general tax cut aimed at offsetting bracket creep. They offered small tax cuts for low income earners to offset the very modest impact of the carbon price/tax. These were clawed back by higher marginal rates so that upper income earners (appropriately) bore the full cost of the carbon price. The key point, stated below, is that the Howard-Rudd tax cuts introduced after the 2007 election were so large that they have more than cancelled out all the subsequent bracket creep.

Increasing GST: not worth the effort?

John Quiggin30 Comments

The Grattan Institute has just released a report suggesting that the government should get more revenue from the GST, either by broadening the base to include food, health and education (yielding an extra $17 billion) or by raising the rate to 15 per cent (yielding an extra $27 billion). As you’d expect from Grattan, the analysis is sound and careful. As long as you accept the standard framing of the tax reform debate, in terms of the need to shift from direct to indirect taxation, it is reasonably convincing.

Grattan suggest using 30 per cent of the extra revenue to increase welfare payments and 30 per cent in cutting the bottom two tax rates, thereby compensating low income earners. The overview concludes:

Around 40 per cent of the additional revenue from a higher GST would be left over after welfare increases and tax cuts. At least some will need to go to state governments to help them address their looming hospital funding gap, as the price for their support of the change. This would leave a little – but not much – to reduce the Commonwealth’s budget deficit, or to pay for other tax cuts that promote economic growth.

(emphasis added).

Is that enough to sell the package? I can’t imagine the states going along with a deal like this for less than 20 per cent of the total extra revenue, which implies the Feds are left with 20 per cent, somewhere between $3.5 and $5.5 billion. From a political viewpoint, it’s hard to see this being worth the effort for the Turnbull government, especially with no guarantee of success.

As a comparison, the FBT concession for motor vehicles, reinstated by Tony Abbott costs the budget around $1.5 billion. Exemptions for non-profits, which have been comprehensively rorted, cost at least as much. Add in a few ‘rats and mice” concessions, and the Federal government would have as much as it could get, in net terms, from the Grattan package (Getting rid of the non-profit concession would probably require some compensating expenditure, but the same is true of the health and education concessions under the GST.)

That’s before we get to the elephants: superannuation concessions (also supported by the Grattan report), corporate tax avoidance, land tax and higher income taxes for (say) the top 5 per cent of income earners (reflecting elite opinion, the Grattan report suggests cutting these rates). All of these are hard, but not obviously harder than the GST.

So, why is GST reform at the top of the government’s list? The answer is simple enough. The advocates of reform haven’t had a new idea, on taxation or anything else, in 30 years. They didn’t get the GST out of Keating’s Tax Summit in 1984 and they didn’t get the version they wanted from Howard and Costello in 2000. So, the same old idea keeps on coming up.

Populism, Patrimonialism and US politics (crosspost from Crooked Timber)

John Quiggin22 Comments

Nuance is nearly always appealing to academics. For a long time, that was true of my approach to economic issues, particularly including income distribution. When presented with simplistic populist solutions to inequality like “Make the rich pay!”, I was inclined to responses along the lines of “It’s more complicated than that”.

A big problem with “Make the rich pay!” is that with the kind of income distribution that prevailed in the mid-to-late 20th century, any change to income tax that would raise significant revenue would have to apply to the top quintile (20 per cent) of the income distribution. People in the top quintile of the income distribution mostly derive their income from (typically professional or para-professional) employment, don’t think of themselves as rich, and aren’t, in general, seen this way by others. So, the slogan didn’t match the implied policy.

But with the rise of the patrimonial society that’s largely ceased to be the case. The top 1 per cent of the US population now get more than 20 per cent of all pre-tax income, considerably more than the total revenue of the Federal government. Within that group, the top 0.1 per cent have done better than everyone else, and the top 0.01 per cent even better.

So, taxing the 1 per cent more makes sense. I responded a little while ago to a piece trying to argue increasing the top marginal tax rate would make no difference to inequality. And while I was drafting this post, the NY Times came out with an article that reached broadly the same conclusion as mine.

There’s nothing inherently ludicrous in the suggestion that the very rich should pay most or all of the costs of sustaining a system that benefits them so greatly[^1]. And, as in the 1920s, the very rich are different from everyone else. Their wealth is derived primarily from capital, or from control over capital (as business owners or from the financial sector). And, while most of the current cohort of ultra-wealthy did not inherit large fortunes, that’s an inevitable consequence of the fact that there weren’t many large fortunes to inherit until recently. As Piketty demonstrates, a society dominated by large accumulations of wealth will inevitably one in which inheritance, rather than effort, education or talent, determines life outcomes.

Would a significant increase in the top (US) marginal income tax rate substantially alter income inequality?

John Quiggin38 Comments

Yes.

This, you might think, qualifies as another in the series “Short Answers to Silly Questions”. But a Brookings Paper study by William G. Gale, Melissa S. Kearney, and Peter R. Orszag reaches the opposite conclusion. (Hat tip: Harry Clarke).

The study looks at increasing the top marginal tax rate (currently 39.6, applicable to incomes above $400k for singles), with the strongest option being an increase to 50 per cent. The proceeds are assumed to be redistributed to households in the bottom 20 per cent of the income distribution.

The headline finding is that the Gini coefficient is barely changed, as are other popular measures including the 99/50 ratio (the ratio of income at the 99-th percentile to 50-th percentile, that is the median). But the 99/10 ratio and 90/10 ratios change a lot, from 50 and 17 under current law to 37 and 12.5 with the redistribution.

What does this mean? Two things:

(i) As is well known, the Gini coefficient is a lousy measure of income inequality, much more sensitive to the middle of the income distribution than to the tails
(ii) The proposed redistribution would substantially improve the welfare of the poor, with most of the burden being borne by taxpayers in or near the top 0.1 per cent.

It’s obvious, as the authors note, that the 90-50 measure won’t change, since neither group is affected (there’s no simulation of behavioral responses which might have indirect effects). But, since the 99-th percentile income is very close to $400k, there’s very little impact on this group either. But the tax, as modelled, raises a lot of money from the ultra-rich incomes. As a result, distributing the proceeds at the bottom of the distribution raises incomes substantially, which explains the big changes in the 90-10 and 99-10 ratios.

The real lesson to be learned here, one I came to pretty slowly myself is that old-style measures looking at quintiles or even percentiles of the income distribution are no longer very relevant. The real question, in the economy of Capital in the 21st Century is how much should go to the ultra-rich.

Is an emissions trading scheme a carbon tax?

John Quiggin23 Comments

I was recently asked this question by ABC Fact Check. Here’s my answer:

The core idea of an ETS is to limit the volume of emissions (of carbon dioxide) by creating a set of permits that must be used by emitters. The permits may initially be auctioned or given away. Since the permits are tradeable a market price will be determined by the demand for permits and the willingness of permit holders to sell their permits. By contrast, a carbon tax sets a price on carbon emissions and allows the market to determine the volume of emissions.

There are a large variety of schemes that resemble the ETS in general structure. Within the environmental area, both the Renewable Energy Target and the government’s Emissions Reduction Fund (if augmented with a baseline allocation and penalty structure) fall into this class. Other examples include taxi licenses, electronic spectrum auctions, and tradeable catch quotas in fisheries. None of these policies is normally described as a tax.

Sea change

John Quiggin25 Comments

Maybe it’s my chronic over-optimism, but it seems to me as if there has been a sudden change in the long-sputtering debate about taxation in Australia. Until a few weeks ago, “tax reform” was, as it had long been, code a “tax mix switch” which in turn was code for “tax food and use the proceeds to cut the company tax rate or the top marginal rate of taxation”. Joe Hockey was still pushing the second part of this package only a week ago.

But the reports coming out of the recent COAG summit seemed to convey a general acceptance that more tax revenue is needed to fund health expenditure in particular. The two top options were an increase in the rate of GST or an increase in the Medicare levy, with little mention of “base broadening” (more code for taxing food).

Meanwhile, Labor has been talking about a Buffett tax, that is, a minimum rate of tax levied on gross incomes, regardless of deductions. And, while the LNP still assumes that it can win by running against a “carbon tax”, that belief seems to have come unmoored from any general theoretical viewpoint. How can Abbott run against a “great big new tax on everything”, if he is happy to discuss a 50 per cent increase in our existing “great big tax on everything”, the GST?

I’m not clear what has happened to bring this about, or whether I’m misreading the signals. But it certainly looks to me as if the great political taboo against even mentioning higher taxes has been broken.

Balancing the books

John Quiggin43 Comments

I’ve been at the Australian Conference of Economists for the last few days. Today we had presentations from the Queensland Treasurer, Curtis Pitt, who is about to bring down his first budget, and from Commonwealth Treasury Secretary, John Fraser.

Curtis Pitt’s big announcement was a rearrangement of debt and equity in Government Owned Corporations, increasing their borrowing and transferring the resulting equity to the general government balance sheet. The result is a $4 billion reduction in general government debt, part of a program to bring the debt/revenue ratio down to around 70 per cent.

A transfer like this doesn’t make any difference to the state’s net financial position. Bu it makes the point that publicly owned assets are assets, not liabilities, and the fact that we own them makes the state’s position stronger. As long as the higher gearing ratio is commercially sensible and the debt can be serviced out of GOC earnings, there’s no reason not to use this to improve measures of general government debt.

Privatisation also makes no difference to the net position, assuming assets are sold at their value in continued public ownership, and the proceeds are used to pay down debt. However, the StrongChoices plan put by the LNP at the last election, would have dissipated around half of the sale proceeds on pork-barrel projects (to be delivered only if the LNP won the seat in question). So, compared to the alternative, Labor’s management is fiscally responsible.

The only measure that is unaffected by balance sheet reshuffles (at least if it is correctly measured) is net worth, and the only way to increase net worth is for income (revenue and asset earnings) to exceed expenditure.

John Fraser’s performance was as expected, which is to say, deeply disappointing. As a colleague sitting at our table remarked, he came across as a politician not a Treasury secretary. Fraser repeated the Henry Review’s criticism of stamp duties and the case for not taxing mobile capital. But when I asked if that meant he supported land taxes, he squibbed the question, waffling on about what a great group of officials he was working with in the states.

The Laffer hypothesis in Australia

John Quiggin34 Comments

I didn’t have time to respond, but the IPA brought Arthur Laffer out to Australia a month or two ago. For those interested, over the fold is a relevant extract from Zombie Economics.

Of rather more concern is the evidence that both the Secretary of the Treasury, John Fraser, and his Deputy for Revenue, Rob Heferen are adherents of the Laffer hypothesis or something very close to it. Fraser gave evidence to the Senate endorsing the Reagan tax cuts (based on Laffer’s hypothesis), while Heferen has claimed that something like 50 per cent of the revenue lost through a company tax cut will be returned through dynamic effects.

Although no issues are ever truly resolved in economics, this informal survey published by Ezra Klein is revealing. Klein asked various people about the tax rate at which revenue would be maximized. His respondents fell into three groups: left/liberal economists, who mostly gave answers around 70 per cent, rightwing pundits with zero credibility who gave answers around 20 per cent, and serious right/centre-right economists, who declined to give a direct answer to the question.

This suggests to me that the debate over the Laffer hypothesis has been won fairly conclusively by the left, and that those on the right would prefer to frame the question in the more defensible (though still, in my opinion, incorrect) claim that we face a long-run trade-off between equality and growth.
