Liberal Democrat travails over the bedroom tax

July 18, 2014 by admin 1 Comment

Well, well, well. It turns out that the bedroom tax isn’t such a good idea after all.

Nick Clegg and Danny Alexander have U-turned on the policy, ostensibly in the light of the (delayed) publication of interim report of the DWP evaluation. The report indicates that the policy largely isn’t achieving the objectives set for it.

Early tabloid headlines announcing that the Liberal Democrats were calling for abolition were misleading. Instead, what Clegg and Alexander would appear to have done is withdraw support for the policy in its current form and adopt a position broadly in line with the motion critical of the bedroom tax passed by Liberal Democrat conference last autumn in Glasgow. To be fair to NC he did state at the time of the Glasgow conference that the independent evaluation would be important in shaping support for the policy. And so, it would appear, it has proved to be.

Crossing boundaries

July 6, 2014 by admin 1 Comment

I spent the back half of last week at the European Network for Housing Research Annual Conference in Edinburgh. The organising committee were kind to me. My paper on the battle over the “bedroom tax” was timetabled for the first morning, so it was soon out the way and I could concentrate on what others had to say.

From my perspective, two themes emerged strongly from the conference. Both related to crossing boundaries. [Read more...]

‘Quackademics’ under fire as critical voices targeted

August 22, 2013 by admin 7 Comments

[Originally posted at The Conversation, 22/08/13]

With independent journalism increasingly under threat, will academics be the next set of critical voices to be targeted? A report calling for research and evidence to have a reduced role in public policy, issued yesterday by a right-wing think-tank, suggests this process is already under way.

These criticisms come after successive governments have sought to encourage academics to leave their ivory towers and influence the wider world. Right now, many academics around the country are knee-deep in final preparations for the next round of research funding. This time around we’ve the additional task of demonstrating how our research has had an impact on the world beyond the academy. In many fields, including my own, that impact is on policy.

At the same time, the government is in the process of establishing a network of “what works” evidence centres for social policy. This government’s commitment to evidence-based policy is perhaps less secure than its precedessor’s, but the idea that research evidence should play a role in policy making remains. [Read more...]

Aggressive intolerance as a substitute for aggressive housing policy?

July 30, 2013 by admin 2 Comments

Something’s been bugging me, but I’ve not fully thought it through. That may well become apparent in a bit.

I’ve a sense there is a link that isn’t being made as effectively as it needs to be.

Within the housing policy community there is a widely shared presumption that housing supply in the UK has been inadequate for at least the last couple of decades. The detailed numbers can be debated, but there is broad agreement that the number of homes constructed annual falls well short of the numbers needed to meet the growth in the household numbers. At the moment we are operating at around half – or perhaps a little more – of the rate of new build that most commentators consider necessary. So the shortfall continues to increase. As a consequence we witness problems of affordability and access. Rapid tenure transformation – the resurgence of private renting – can also, partly, be explained by this lack of supply.

Reinhart and Rogoff: replication and responsibility

April 18, 2013 by admin 2 Comments

… the actions of economists today bear on the life chances of the world’s population far more substantially than do the actions of the members of most other professions.

George DeMartino

Replication is an activity that doesn’t attract enough attention, enough credit, or enough effort in the social sciences. But it is an activity that is getting a lot of attention at this precise moment. This has come courtesy of the exposure of both flaws and contestable methodological choices in Reinhart and Rogoff’s landmark study of public debt and economic growth.

The economic blogosphere has exploded with debate over the issue. But, just in case you’re not following it, here are the key points. Reinhart and Rogoff followed up their major historical work looking at debt and economic growth This time is different with a paper called Growth in a time of debt published in the American Economic Review in 2010. Their key result is that levels of public debt in excess of 90% of GDP are associated with lower rates of economic growth. Indeed, the mean annual growth rate they report, once debt crosses the 90% threshold, is negative.

This body of work is highly influential.

A quick search on Google Scholar will tell you that the NBER version of Growth in a time of debt has been cited 450 times, while This time is different has been cited over 2000 times since 2009. That is a lot of citations for social science publications: you’re doing pretty well once citations for a piece get into double figures within four years.

In a paper published this week, Thomas Herndon, Michael Ash, and Robert Pollin (HAP) of the University of Massachusetts, Amherst identify problems with the Reinhart and Rogoff result. [Read more...]

Evidence or otherwise on Housing Benefit reform

March 31, 2013 by admin 3 Comments

The mainstream media seem finally to have cottoned on to the fact that our welfare system is to undergo substantial change tomorrow. I mentioned a couple of months ago that the changes around the so-called bedroom tax were, belatedly, attracting broader media interest. And the media are connecting the deathly dry changes to the regulations to real life stories of hardship. They’ve also started to join up the dots to realise that it could well turn out that April is, indeed, the cruellest month.

Some of us have been banging on about the potentially negative implications of these changes for some months, if not years. It is good that they are now achieving some serious public profile. But it is a bit late to head off the chaos that could well follow their implementation.

What precisely will follow the raft of changes during April is a bit of a moot point. Will the prognostications of catastrophe be correct? Or will the Government’s much more sanguine view be borne out? Clearly, it is an issue of great significance.

It emerged as a key area of contention in the report on the impact of housing benefit reform published by the Public Accounts Committee last week. [Read more...]

Research and the policy process

February 13, 2013 by admin 2 Comments

[This text accompanies a presentation made to a SW Crucible event on 13^th February]

In this post I offer a perspective on academic research and the Whitehall policy process. It draws on interactions of various types in and around Whitehall going back to the start of the Major government. That includes having been involved in quite a few research projects and evaluations contracted by government departments and quangos.

One point to make at the outset is that different Whitehall departments have very different cultures, including their orientation towards research – they differ in where research sits in relation to other considerations as an input into policy thinking. And of course practice within Departments evolves over time. So I’m not sure there are many truly general lessons to be drawn.

So this is just one perspective, albeit a perspective that is also informed by the literature on research utilization. There are no doubt others with different experiences and different insights to share.

I want to make some comments under six headings. [Read more...]

Appraising health reform

February 25, 2012 by admin Leave a Comment

Blogging is a fantastic medium for providing a brief statement of your views. Or for building an argument involving a small number of points. Or, perhaps, for giving a high level summary of a more complex argument.

But it’s not a great medium through which to appraise complex arguments or carefully weigh the evidence. Where a blog draws explicitly on evidence it tends to draw on one or two studies to illustrate its point. For some purposes that works just fine. But for others it can be misleading. It can give the impression that there is a robust evidence base to back up the points being made, whereas in fact the evidence is being cherry-picked. The weight of evidence may lie with the other side of the argument. Or, more likely, the evidence does not offer many simple messages.

A couple of weeks ago I made this point in the comment thread on a blog post about competition and choice in public service reform. It wasn’t entirely warmly received by some other commenters. [Read more...]

Is nudging enough?

July 31, 2011 by shodanalexm Leave a Comment

Rene Kinzett, one of my fellow contributors over at Dale & Co, posted Nudging or Nannying last weekend. The argument was perhaps a little cryptic, but the point was that relying on the subtlety of trying to “nudge” behaviour in the right direction is not an adequate policy response to certain types of problem. His example of treating rickets among young women who for cultural reasons do not have enough exposure to sunlight is an interesting one. He referred to minimum alcohol pricing, a policy being introduced in Scotland, and banning smoking in cars carrying children, a policy being introduced in Wales, as more conventional regulatory policy that will help those on the edges of society, when nudges are judged inadequate.

A couple of commenters took Kinzett to task for this argument. One made the point that nudge theory is being preferred for developing policy at the moment because it has been shown to be more effective than traditional regulatory approaches. It was also arguing that no one is suggesting that nudge can be used in isolation and should be combined with other mechanisms to deliver better social outcomes.

It seems to me that these comments miss the mark in at least a couple of ways. [Read more...]
