Woman economists "just think different". Really?

Survey "finds gender gap".

There's a new study out that claims to find "significant differences" between the ways male and female economists think. At least, that's the way it's being reported:

Here's the USA today headline:                                                               

He said, she said: Economists' views differ by gender

Women economists see the world differently                                  

Sciencedaily.com:

National Survey of Economists Uncovers Vast Gender Gap in Policy Views                                                                                                     

So men and women just think differently... even when given the same training, and broad agreement in terms of core economic principles and methodology? Must be biology.

Or is it? A closer look at the study, which questioned several hundred members of the American Economic Association, shows the biggest difference in thinking is on gender discrimination in their own field: 76 per cent of female economists say men are favoured when it comes to faculty opportunities in economics, and 80 per cent of male economists say women are favored or that there is no favouritism.

Here are the other differences:

  • Men are 20 per cent more likely to think the US and EU have too much government regulation.
  • Women are 24 per cent more likely to believe the US government is too small.
  • Women are 41 per cent more likely to favour a more progressive tax system.
  • Men are 31 per cent less likely to agree with making US income distribution more equal.
  • Women are less likely to support Arctic drilling.
  • Men are more likely to support voucher use in education.

There's a pattern here: women consistently vote in favour of policies which correct discrimination. As a discriminated-against group, this isn't surprising. Hardly sure evidence of different male/female "wiring".

I'd hazzard a guess that this study was commissioned to help rather than hinder equality drives. But flagging its findings as evidence of tomato/tomahto thinking between the genders is not likely to do the job.

To preserve the environment we hold in common, everyone has to play their part

The challenge of building a clean future based on the common good of Londoners demands that politicians, business, communities and individuals each take a share of the responsibility and of the benefits.

The environmental challenge facing our capital city can seem overwhelming. Our air is poisonous. Our infrastructure built for the fossil fuel era. The need to build a clean, low carbon future can seem incompatible with competing challenges such as protecting energy security, housing and jobs.

The way we tackle this challenge will say a lot about the type of city we are. We inherit the world we live in from the generations that went before us, and only hold it until it is time to hand it over to future generations. The type of environment we leave behind for our children and grandchildren will be affected by the decisions we need to take in the short term. Our shared inheritance must be shaped by all of us in London.

Londoners currently face some crucial decisions about the way we power our city. The majority of us don't want London to be run on dirty fuel, and instead hope to see a transition to a clean energy supply. Many want to see that clean energy sourced from within London itself. This is an appealing vision: there are upsides in terms of costs, security and, crucially, the environment.

Yet the debate about how London could achieve such a future has remained limited in its scope. Air pollution has rightly dominated the environmental debate in this year’s mayoral election, but there is a small and growing call for more renewable deployment in the city.

When it comes to cities, by far the most accessible, useable renewable energy is solar, given you can install it on some part of almost every roof. Rooftop solar gives power to the householder, the business user, the public servant - anyone with a roof over their head.  And London has upwards of one million roofs. Yet it also has the lowest deployment of solar of any UK city. London can do better. 

The new mayor should take this seriously. Their leadership will be vital to achieving the transition to clean energy. The commitments of the mayoral frontrunners should spur other parts of society to act too. Zac Goldsmith has committed to a tenfold increase in the use of solar by 2025, and Sadiq Khan has pledged to implement a solar strategy that will make the most of the city’s roofs, public buildings and land owned by Transport for London.

While the next mayor will already have access to some of the tools necessary to enact these pledges (such as the London Plan, the Greater London Assembly and TfL), Londoner’s must also play their part. We must realise that to tackle this issue at the scale and speed required the only way forward is an approach where everyone is contributing.

A transition to solar energy is in the best interests of citizens, householders, businesses and employees, who can begin to take greater control of their energy.  By working together, Londoners could follow the example of Zurich, and commit to be a 2,000 watt society by 2050. This commitment both maximizes the potential of solar and manages introduces schemes to effectively manage energy demand, ensuring the city can collectively face an uncertain future with confidence.

Unfortunately, national policy is no longer sufficient to incentivise solar deployment at the scale that London requires. There is therefore an important role for the incoming Mayor in facilitating and coordinating activity. Whether it is through TfL, existing community energy schemes, or through individuals, there is much the mayor can do to drive solar which will benefit every other city-dweller and make London a cleaner and healthier place to live.

For example the new mayor should work with residents and landlords of private and social housing to encourage the deployment of solar for those who don’t own their property. He should fill the gap left by national building standards by ensuring that solar deployment is maximized on new build housing and commercial space. He can work with the operator of the electricity grid in the capital to maximize the potential of solar and find innovative ways of integrating it into the city’s power demand.

To bring this all together London should follow the example set by Nottingham and Bristol and create it’s own energy company. As a non-profit company this could supply gas and electricity to Londoners at competitive prices but also start to drive the deployment of clean energy by providing an attractive market for the power that is generated in the city. Community schemes, businesses and householders would be able to sell their power at a price that really stacks up and Londoners would receive clean energy at competitive prices.

The challenge of building a clean future based on the common good of Londoners demands that politicians, business, communities and individuals each take a share of the responsibility and of the benefits. Lets hope the incoming Mayor sees it as their role to convene citizens around this aim, and create incentives to virtue that encourage the take up and deployment of solar, so that we have a healthy, clean and secure city to pass on to the next generation.
