On microfoundations

Some recent post on the necessity of microfoundations that I found interesting.

  1. Issues about microfoundations.
  2. Why you don’t need rigorous microfoundations.
  3. UpdateZombie Marx – illustrating the similarities between Marxism and Neo-classical economics.  ht Guan.

I agree with these in part, especially when it comes to macroeconomics (whether this is appropriate depends on your view on the nature of how we should treat macroeconomic aggregates).  But as with all things it is a matter of balance.

QOTD: Déformation professionnelle

Every specialist, owing to a well-known professional bias, believes that he understands the entire human being, while in reality he only grasps a tiny part of him.

Quote of the day: The debt burden, and the use of burden

I have just moved house, and while doing so I discovered a bunch of old books that my brother had loaned to me.  One of these was the Foundations of Economic Thought (1990) – a good title, so I figured I’d give it a bit of a read.

Within the book is a series of self-contained essays which mix economic history with economic ideas and methods – I am a big fan of this sort of thing.  I’ve just been reading the essay “the debt burden” by Brian Hillier and M. Teresa Lunati.  In this essay they discuss the issues I was trying to get across to a general audience in the series on tax, specifically in my last post.  In the final post I make the point that borrowing is really another form of broad “taxation”, but as when discussing different types of taxation we are asking where the burden lies.

However, the quote I’m going to pull isn’t directly about that.  It is about the use of the word burden.

Thinking on the US Fed mandate

Via Mark Thoma, I spotted this piece in the Washington Post about the US Fed’s mandate. 

I disagree with this piece.  But, it is well laid out and argued – which makes it a good piece!  So let us go through the reason why I take issue:

Careful making us an aggregate happiness machine

Last week Matt Nolan discussed the idea that being too target focused can be dangerous (Infometrics link here):

Instead of targeting an arbitrary set of outputs that treat New Zealand like a machine, policy should be based on the inherent trade-offs that exist for the policy question we are asking.  Focused research on the costs and benefits of educational achievement, health outcomes, benefit policy etc – these are the ways we can incrementally improve policy, and build a better society together.

These outputs may suggest to us there is an issue that deserves investigations– but they should not be seen as an end to themselves.

Policy justified on the basis of the target of an arbitrary GDP or happiness index doesn’t do this, and instead threatens to tie our outcomes closer and closer to someone else’s view of what is right, what is just, what is happiness, and what wellbeing.  Instead the aim of government policy should be to ensure people in society have the ability to reach, and access to, choices that allow them to gain wellbeing.

A factor that often gets missed when discussing policy options in public is that the real “target” is not observable.  If we are not careful about the way “observable” things translate into the underlying issues we really care about, we will make a lot of false policy conclusions.

One of the reasons economists use a counterfactual that involves no government involvement is because of the idea of “revealed preferences” – that individuals will make choices that reveal the value they place on things.  Individuals know (at least to a greater degree) what they value, while the rest of us cannot hop into the minds of others and figure out what they value.

A clear view of trade-offs, and the use of markets to help ensure people reveal preferences, gets us a long way. Given that we can then go about considering the views of co-ordination that Matt also touched on last week.

 

Having skills and using them are very different

The OECD have recently released a new survey of skills and it has prompted plenty of wailing about the failings of the English education system. The crucial slide from Andreas Schleicher’s summary is this one: It shows that English adults have excellent literacy skills relative to their peers internationally but young people have fallen well behind. Given the efforts that have been put into the UK’s schooling system over the last few decades it charts a depressing decline. Hearteningly, it is not the full story of the survey. Read more
