MIT academics propose carbon tax as the solution to America's deficit problems

Compared to the fiscal cliff, a carbon tax would boost growth while cutting emissions.

The Washington Post's Brad Plumer reports on a paper from the MIT Global Change Institute which argues that a carbon tax could, and should, replace the Bush tax cuts in the US.


The authors model what would happen if, this December, Congress enacted a small fee on carbon emissions to fend off a portion of the tax hikes and spending cuts that are scheduled to occur. The carbon tax would be levied directly on fossil fuels—on coal that comes out of the mine, say, or oil that’s shipped in from overseas—and would start at $20 per ton of carbon in 2013, rising 4 percent each year thereafter.

The authors, Sebastian Rausch and John M. Reilly, estimate that this tax would raise $1.5 trillion over the next 10 years.

To advocates of a carbon tax, this paper ought to be a mixed blessing.

On the one hand, the framing of the tax in terms of sensible deficit reduction is one of the better ways to get it in the debate. In both Britain and America, there is – for good or ill – an agreement that high deficits are a major problem which needs to be dealt with, and so hitching any policy to that cause is a far better recipe for success than pointing out its efficacy at fighting climate change.

On the other, the purpose of the tax could get muddled if this is how the debate is to proceed. Look, for example, at debates over the Robin Hood tax. No-one can agree whether it is being implemented to raise revenues, cut down on practices like high-frequency trading, or some undefined mixture of the two.

With a Robin Hood tax, that may be an acceptable confusion, but with a carbon tax, it is undoubtedly introduced to reduce carbon emissions. To think otherwise would be dangerous indeed. And so yoking a deficit reduction program to the tax creates some perverse incentives on the part of lawmakers. For if the tax does succeed in reducing carbon emissions – which the authors of the MIT paper suggest it will, though not by nearly enough to single-handedly solve the problem for the US – then the revenues gathered by it will drop accordingly.

Even so, having a carbon tax is still better than not having one, and the choke point the authors identify – the US fiscal cliff, and all the uncertainty it brings with it – could well be a time for introducing novel legislation of all stripes to the house.

Why is the government charging more women for selling sex but turning a blind eye to buyers?

Since 2013, the number of women charged for selling sex gone up while the number of men charged for buying it has gone down.

It’s no surprise that prostitution policy is an area rarely visited by our legislators. It’s politically charged - a place where the need to prevent exploitation seemingly clashes head on with notions of liberal freedom; where there are few simple answers, a disputed evidence base, and no votes.

There’s also little evidence to suggest that MPs are different from the rest of the population - where one-in-ten men have purchased sex. It is little wonder therefore that our report on how the law should change, published in 2014, was the first major cross-party intervention on the subject in twenty years.

Some take the view that by removing all legal constraints, it will make the inherently exploitative trade of prostitution, safer. It’s not just me that questions this approach, though I accept that - equally - there’s no consensus that my preferred measure of criminalising the purchase of sex, while decriminalising the sale, would fundamentally change the scale of the problem.

Where all sides come together, however, is in the desire to see women diverted from the law courts. It is still possible for women (and it still is women; prostitution remains highly genderised) to go to prison for offences related to prostitution. Today, in 2015.

The total number of prosecutions for all prostitution offences in England and Wales has been decreasing since 2010, but not in a uniform fashion. This does not reflect a reduction in the size of the trade, or the violent nature of it.

There were once consistently more prosecutions for kerb crawling, profiting, and control of prostitution. But since 2013, there have been more prosecutions for soliciting or loitering than for profit from prostitution and kerb crawling each year.

In simple terms, offences committed by men with choice, freedom and money in their pocket are having a blind eye turned to them, while women are being targeted - and this trend is accelerating. In the law courts, and in prosecutions, it is the most vulnerable party in the transaction, who is taking the burden of criminality.

Take on-street sex buying as an example. In 2013-14 just 237 prosecutions were brought for kerb crawling, but there were 553 - more than twice as many - for loitering and soliciting.

There is a similar pattern in the 2014/15 figures: 227 charges for kerb crawling reached court, while 456 prosecutions were initiated against those who were selling sex. Just 83 prosecutions for control of prostitution, or ‘pimping’, were brought in that same year.

These are men and women on the same street. It takes a high level of liberal delusion to be convinced that prostitution is caused by a surge of women wishing to sell sex, rather than men who wish to buy it. And yet women who sell sex are the ones being targeted in our law courts, not the men that create the demand in the first place.

This situation even goes against the Crown Prosecution Service’s (CPS) own guidance. They say:

“Prostitution is addressed as sexual exploitation within the overall CPS Violence Against Women strategy because of its gendered nature… At the same time, those who abuse and exploit those involved in prostitution should be rigorously investigated and prosecuted, and enforcement activity focused on those who create the demand for on-street sex, such as kerb crawlers.”

Why then, is this happening? For the same reason it always does - in our criminal justice system stigmatised, poor women are valued less than moneyed, professional men.

My debate in Parliament today raises these issues directly with the government ministers responsible. But to be honest, the prosecution-bias against women in the courts isn’t the problem; merely a symptom of it. This bias will only be tackled when the law reflects the inherent harm of the trade to women, rather than sending the mixed signals of today.

That’s why I welcome the work of the End Demand Alliance, composed of over 40 organisations working to end the demand that fuels sex trafficking and prostitution, advocating the adoption of the Sex Buyer Law throughout the UK.

This would criminalise paying for sex, while decriminalising its sale and providing support and exiting services for those exploited by prostitution. Regardless of these big changes in the law, I don’t see how anyone can support the current state of affairs where there are more prosecutions brought against women than men involved in prostitution.

The authorities are targeting women because they're easier to arrest and prosecute. It goes against their own guidance, common sense and natural justice.
And it needs to stop.
