Osborne will score a financial own-goal tomorrow

The Chancellor, in turning down the chance to implement a Financial Transactions Tax, will cost the UK dearly.

A fiscal measure that could raise £8bn, boost GDP by 0.25 per cent, provide vital funds for job-creation, infrastructure projects and poverty reduction, calm excessive speculation and reduce the regularity of financial crashes would seem like a no-brainer for a Chancellor. Struggling to reduce the deficit and bring public finances under control, George Osborne is set to score an own goal by refusing to sign up for the Financial Transaction Tax (FTT) which is rapidly becoming a reality in Europe.

Twelve European countries, including the big economies of Germany, France, Italy and Spain, have agreed to a small transaction tax of 0.1 per cent on equities and bonds and 0.01 per cent on derivatives. The initiative, which could generate €37bn per year, is expected to be given the green light by the European Parliament on 12 December.

The UK government’s reasons for rejecting the FTT are flawed on many counts. The Chancellor stubbornly clings to the argument that the FTT must be global to work. This ignores the fact that over 40 countries including some of the world’s leading financial centres and dynamic economies, have successfully implemented FTTs.

Hong Kong raises £1.7bn a year through taxes on derivative transactions while South Korea raises £3.8bn. Even Switzerland and the US have their own taxes on transactions which do not seem to have harmed their reputations as financial centres. Indeed, the UK’s very own stamp duty of 0.5 per cent on share transactions currently raises about £3bn a year for the Treasury; much of this tax (around 40 percent) is paid by people, including non-British, based abroad, who trade in UK shares.

Another myth often touted is that ordinary people and pensioners will end up paying the price. But the rate for the FTT is set so low precisely to avoid hitting longer term investments such as people’s pensions. On the contrary, a paper published this week shows that the FTT is an opportunity to help safeguard pensioners’ investments through reducing short-term speculative activity and encouraging pension funds to return to their traditional, less risky role as buy-and-hold investors - exactly the sort of cautious, long-term funds which experienced the most growth over the rocky 2008-2010 period.

Sparked by recent low interest rates, the increased turnover of assets amongst pension funds contributes to management costs of between two and 20 per cent. It is these high fees - reaped by intermediaries such as advisers, managers and brokers - that are having a major impact on pensioners’ returns.

The tax will also help improve market stability by reducing high-frequency trading including computer-driven trading in which shares are bought and sold hundreds of times a second. Virtually unheard of seven years ago, high frequency trading now accounts for up to 77 percent of all trading in UK equities.

Dictated by computers, too fast for humans to monitor, high frequency trading can create sudden crashes and wild fluctuations in stock prices that bear no relation to market fundamentals and serve little economic purpose. Applying a tiny tax every time a stock is traded will dramatically reduce the incentive to use computers at lightening speeds as the tax outweighs the wafer-thin profits. This will improve financial stability and help reduce the likelihood of future crises, which can lead to a higher level of GDP in the future.

If a levy of 0.1 per cent also makes other elements of City trading unprofitable, you have got to ask how valuable was that activity in the first place?

By triggering a shift away from short-term trading in favour of long-term holding the FTT will thus help reduce misalignments in markets and their subsequent abrupt adjustments or crashes, decreasing the likelihood of future crises. Indeed, countries with FTTs were amongst those least affected by the 2008 crash.

At a time when the UK government continues to struggle with the impact of a crisis that will according to the Bank of England, ultimately cost the UK at least £1.8trn and as much as £7.4trn in lost GDP, it seems reasonable to expect the financial sector, largely responsible for creating the crisis, not just to contribute to repair the damage but also to adopt measures to help reduce the likelihood of future crises.

To us and 50 other financiers who wrote to David Cameron and other European leaders in support of the tax, it is clear the FTT would help rein in markets, help kick-start national economies and provide money to help the world’s poorest countries. The FTT will shortly be a reality in Europe’s biggest economies. The UK cannot afford to ignore it.

This Ada Lovelace Day, let’s celebrate women in tech while confronting its sexist culture

In an industry where men hold most of the jobs and write most of the code, celebrating women's contributions on one day a year isn't enough. 

Ada Lovelace wrote the world’s first computer program. In the 1840s Charles Babbage, now known as the “father of the computer”, designed (though never built) the “Analytical Engine”, a machine which could accurately and reproducibly calculate the answers to maths problems. While translating an article by an Italian mathematician about the machine, Lovelace included a written algorithm for which would allow the engine to calculate a sequence of Bernoulli numbers.

Around 170 years later, Whitney Wolfe, one of the founders of dating app Tinder, was allegedly forced to resign from the company. According to a lawsuit she later filed against the app and its parent company, she had her co-founder title removed because, the male founders argued, it would look “slutty”, and because “Facebook and Snapchat don’t have girl founders. It just makes it look like Tinder was some accident". (They settled out of court.)

Today, 13 October, is Ada Lovelace day – an international celebration of inspirational women in science, technology, engineering and mathematics (STEM). It’s lucky we have this day of remembrance, because, as Wolfe’s story demonstrates, we also spend a lot of time forgetting and sidelining women in tech. In the wash of pale male founders of the tech giants that rule the industry,we don't often think about the women that shaped its foundations: Judith Estrin, one of the designers of TCP/IP, for example, or Radia Perlman, inventor of the spanning-tree protocol. Both inventions sound complicated, and they are – they’re some of the vital building blocks that allow the internet to function. 

And yet David Streitfield, a Pulitzer-prize winning journalist, someow felt it accurate to write in 2012: “Men invented the internet. And not just any men. Men with pocket protectors. Men who idolised Mr Spock and cried when Steve Jobs died.”

Perhaps we forget about tech's founding women because the needle has swung so far into the other direction. A huge proportion – perhaps even 90 per cent - of the world’s code is written by men. At Google, women fill 17 per cent of technical roles. At Facebook, 15 per cent. Over 90 per cent of the code respositories on Github, an online service used throughout the industry, are owned by men. Yet it's also hard to believe that this erasure of women's role in tech is completely accidental. As Elissa Shevinsky writes in the introduction to a collection of essays on gender in tech, Lean Out: “This myth of the nerdy male founder has been perpetuated by men who found this story favourable."

Does it matter? It’s hard to believe that it doesn’t. Our society is increasingly defined and delineated by code and the things it builds. Small slip-ups, like the lack of a period tracker on the original Apple Watch, or fitness trackers too big for some women’s wrists, gesture to the fact that these technologies are built by male-dominated teams, for a male audience.

In Lean Out, one essay written by a Twitter-based “start-up dinosaur” (don’t ask) explains how dangerous it is to allow one small segment of society to built the future for the rest of us:

If you let someone else build tomorrow, tomorrow will belong to someone else. They will build a better tomorrow for everyone like them… For tomorrow to be for everyone, everyone needs to be the one [sic] that build it.

So where did all the women go? How did we get from a rash of female inventors to a situation where the major female presence at an Apple iPhone launch is a model’s face projected onto a screen and photoshopped into a smile by a male demonstrator?

The toxic culture of many tech workplaces could be a cause or an effect of the lack of women in the industry, but it certainly can’t make make it easy to stay. Behaviours range from the ignorant - Martha Lane-Fox, founder of, often asked “what happens if you get pregnant?” at investors' meetings - to the much more sinister. An essay in Lean Out by Katy Levinson details her experiences of sexual harassment while working in tech: 

I have had interviewers attempt to solicit sexual favors from me mid-interview and discuss in significant detail precisely what they would like to do. All of these things have happened either in Silicon Valley working in tech, in an educational institution to get me there, or in a technical internship.

Others featured in the book joined in with the low-level sexism and racism  of their male colleagues in order to "fit in" and deflect negative attention. Erica Joy writes that while working in IT at the University of Alaska as the only woman (and only black person) on her team, she laughed at colleagues' "terribly racist and sexist jokes" and "co-opted their negative attitudes”. 

The casual culture and allegedly meritocratic hierarchies of tech companies may actually be encouraging this discriminatory atmosphere. HR and the strict reporting procedures of large corporates at least give those suffering from discrimination a place to go. A casual office environment can discourage reporting or calling out prejudiced humour or remarks. Brook Shelley, a woman who transitioned while working in tech, notes: "No one wants to be the office mother". So instead, you join in and hope for the best. 

And, of course, there's no reason why people working in tech would have fewer issues with discrimination than those in other industries. A childhood spent as a "nerd" can also spawn its own brand of misogyny - Katherine Cross writes in Lean Out that “to many of these men [working in these fields] is all too easy to subconciously confound women who say ‘this is sexist’ with the young girls who said… ‘You’re gross and a creep and I’ll never date you'". During GamerGate, Anita Sarkeesian was often called a "prom queen" by trolls. 

When I spoke to Alexa Clay, entrepreneur and co-author of the Misfit Economy, she confirmed that there's a strange, low-lurking sexism in the start-up economy: “They have all very open and free, but underneath it there's still something really patriarchal.” Start-ups, after all, are a culture which celebrates risk-taking, something which women are societally discouraged from doing. As Clay says, 

“Men are allowed to fail in tech. You have these young guys who these old guys adopt and mentor. If his app doesn’t work, the mentor just shrugs it off. I would not be able ot get away with that, and I think women and minorities aren't allowed to take the same amount of risks, particularly in these communities. If you fail, no one's saying that's fine.

The conclusion of Lean Out, and of women in tech I have spoken to, isn’t that more women, over time, will enter these industries and seamlessly integrate – it’s that tech culture needs to change, or its lack of diversity will become even more severe. Shevinsky writes:

The reason why we don't have more women in tech is not because of a lack of STEM education. It's because too many high profile and influential individuals and subcultures within the tech industry have ignored or outright mistreated women applicants and employees. To be succinct—the problem isn't women, it's tech culture.

Software engineer Kate Heddleston has a wonderful and chilling metaphor about the way we treat women in STEM. Women are, she writes, the “canary in the coal mine”. If one dies, surely you should take that as a sign that the mine is uninhabitable – that there’s something toxic in the air. “Instead, the industry is looking at the canary, wondering why it can’t breathe, saying ‘Lean in, canary, lean in!’. When one canary dies they get a new one because getting more canaries is how you fix the lack of canaries, right? Except the problem is that there isn't enough oxygen in the coal mine, not that there are too few canaries.” We need more women in STEM, and, I’d argue, in tech in particular, but we need to make sure the air is breatheable first.
