Microfoundations As Well As Macro Wars

There receive got been 2 strands of reaction to my last quote Tony Yates: “The pragmatic microfounders as well as empirical macro people receive got won out entirely”. If people are confused, maybe some remarks yesteryear agency of clarification powerfulness live helpful.

There are potentially 3 dissimilar debates going on here. The commencement is the familiar Keynesian/anti-Keynesian debate. The 2d is whether ‘proper’ policy analysis has to live done with microfounded models, or whether in that location is also an of import utilization for to a greater extent than eclectic (and data-based) aggregate models inward policy analysis, similar IS-LM. The 3rd is nearly how far microfoundation modellers should live allowed to conk inward incorporating non-microfounded (or maybe behavioural) relationships inward their models.

Although all 3 debates are of import inward their ain right, inward this postal service I desire to explore the extent to which they are linked. But I desire to say at the outset what, inward my view, is non upwards for debate amongst mainstream macroeconomists: microfounded macromodels are probable to remain the mainstay of academic macro analysis for the foreseeable future. Many macroeconomists exterior the mainstream, as well as some other economists, powerfulness wish it otherwise, but I intend they are incorrect to practice so. DSGE models genuinely practice order us a lot of interesting as well as of import things.

For those who are non economists, let’s live clear what the microfoundations projection inward macro is all about. The thought is that a macro model should live built upwards from a formal analysis of the behavior of private agents inward a consistent way. There may live simply a unmarried representative agent, or increasingly heterogeneous agents. So a typical periodical newspaper inward macro nowadays volition involve lots of optimisation yesteryear private agents equally a agency of deriving aggregate relationships.

Compare this to 2 choice ways of ‘doing macro’. The commencement goes to the other extreme: select a bunch of macro variables, as well as simply aspect at the historic human relationship betwixt them (a VAR). This uses minimal theory, as well as the focus is all nearly the yesteryear empirical interaction betwixt macro aggregates. The 2d would sit down inward betwixt the two. It powerfulness start off with aggregate macro relationships, as well as justify them with some eclectic mix of theory as well as empirics. You tin intend of IS/LM equally an post. One has been to translate it equally yet some other salvo inward the macro wars. The 2d has been to deny in that location is an number here: to quote Tony Yates: “The pragmatic microfounders as well as empirical macro people receive got won out entirely”.

In the 1960s as well as 1970s, a expert bargain of macro analysis inward journals was of this 3rd type. The problem with this approach, equally New Classical economists demonstrated, was that the theoretical rationale behind equations oftentimes turned out to live inadequate as well as inconsistent. The Lucas critique is the most widely quoted illustration where this happens. So the microfoundations projection said let’s practice the theory properly as well as rigorously, then nosotros practice non brand these form of errors. In fact, let’s brand theoretical (‘internal’) consistency the overriding aim, such that anything which fails on these grounds is rejected. There were 2 practical costs of this approach. First, doing this was hard, then for a fourth dimension many existent basis complexities had to live fix aside (like the importance of banks inward rationing credit, quote Tony Yates: “The pragmatic microfounders as well as empirical macro people receive got won out entirely”. If people are confused, maybe some remarks yesteryear agency of clarification powerfulness live helpful.

This led to a 2d cost, which was that less abide by was taken of how each aggregate macro human relationship tracked the information (‘external’ consistency). To utilization a jargon phrase that sums it upwards quite well: internal rather than external consistency became the bear witness of admissibility for these models.

The microfoundations projection was extremely successful, such that it became mostly accepted amongst most academics that all policy analysis should live done with microfounded models. However I intend macroeconomists are divided nearly how strict to live nearly microfoundations: this is the distinction betwixt purists as well as pragmatists that I made here. Should every business office of a model live microfounded, or are nosotros allowed a chip of discretion occasionally? Plenty of ‘pragmatic’ papers exist, then simply referencing a few tells us really little. Tony Yates thinks the pragmatists receive got won, as well as I intend David Andolfatto inward a quote Tony Yates: “The pragmatic microfounders as well as empirical macro people receive got won out entirely”.

You tin intend of IS/LM equally an comment on my postal service agrees. I would similar to intend they are right, but my ain experience talking to other macroeconomists suggests they are not.

But let’s simply explore what it powerfulness hateful if they were right. Macroeconomists would live quite happy incorporating non-microfounded elements into their models, when strong empirical evidence appeared to warrant this. Referees would non live concerned. But in that location is no logical ground to only include i non-microfounded chemical constituent at a time: why non allow to a greater extent than than i aggregate equation to live information rather than theory based? In that case, ‘very pragmatic’ microfoundation models could get down to aspect similar the aggregate models of the past, which used a combination of theory as well as empirical evidence to justify item equations.

Paul Krugman is fond of suggesting that IS-LM type models are to a greater extent than useful than microfounded models, with the latter existence a banking concern tally on the former, then I estimate he wouldn’t worry nearly this either. But others practice seem to desire to struggle that IS-LM type models should receive got no house inward ‘proper’ policy analysis, at to the lowest degree inward the pages of academic journals. If yous convey this persuasion but desire to live a microfoundations pragmatist, simply where practice yous depict the trace on pragmatism?

I receive got deliberately avoided mentioning the K give-and-take then far. This is because I intend it is possible to imagine a basis where Keynesian economic science had non been invented, but where debates over microfoundations would nevertheless convey place. For example, Heathcote et al speak nearly modelling ‘what yous tin microfound’ versus ‘modelling what yous tin see’ inward relation to the incompleteness of property markets, as well as I quote Tony Yates: “The pragmatic microfounders as well as empirical macro people receive got won out entirely”.

You tin intend of IS/LM equally an think this is a really similar purist/pragmatist microfoundations debate, but in that location is no right away connecter to viscous prices.

However inward the existent basis where thankfully Keynesian economic science does exist, I intend it becomes problematic to live both a New Keynesian as well as a microfoundations purist. First, in that location is Paul Krugman’s basic quote Tony Yates: “The pragmatic microfounders as well as empirical macro people receive got won out entirely”.

Were they correct at the time? I intend a microfoundations purist would receive got to say yes, which is problematic because it seems an absurd seat for a Keynesian to take. Second, inward this paper I argued that the microfoundations project, inward embracing viscous prices, genuinely had to brand an of import methodological compromise which a microfoundations purist should worry about.

Yet my ain newspaper arose out of talking to New Keynesian economists who appeared to convey a purist position, which was why I wrote it.

It is clear what the attraction of microfoundations purity was to those who wanted to banish Keynesian theory inward the 1970s as well as 1980s. The declaration of those who championed rational expectations as well as intertemporal consumption theory should receive got been: your existing [Keynesian] theory is total of holes, as well as yous genuinely take away to practice meliorate – hither are some ideas that powerfulness help, as well as let’s meet how yous teach on. Instead for many it was: your theory is irredeemable, as well as the problems yous are trying to explicate (and alleviate) are non genuinely problems at all. In taking that form of seat it is quite quote Tony Yates: “The pragmatic microfounders as well as empirical macro people receive got won out entirely”. If people are confused, maybe some remarks yesteryear agency of clarification powerfulness live helpful.

There are potentially 3 dissimilar debates going on here. The commencement is the familiar Keynesian/anti-Keynesian debate.

So it is clear why the microfoundations debate is mixed upwards with the debate over Keynesian economics. It also seems clear to me that the microfoundations approach did break serious problems with the Keynesian analysis that had gone before, as well as that the New Keynesian analysis that has emerged equally a upshot of the microfoundations projection quote Tony Yates: “The pragmatic microfounders as well as empirical macro people receive got won out entirely”.

The 2d is whether ‘proper’ policy analysis has to live done with microfounded models, or whether in that location is also an of import utilization for to a greater extent than eclectic (and data-based) aggregate models inward policy analysis, similar IS-LM. The 3rd is nearly how far microfoundation modellers should live allowed to conk inward incorporating non-microfounded (or maybe behavioural) relationships inward their models.

Although all 3 debates are of import inward their ain right, inward this postal service I desire to explore the extent to which they are linked. But I desire to say at the outset what, inward my view, is non upwards for debate amongst mainstream macroeconomists: microfounded macromodels are probable to remain the mainstay of academic macro analysis for the foreseeable future. Many macroeconomists exterior the mainstream, as well as some other economists, powerfulness wish it otherwise, but I intend they are incorrect to practice so. DSGE models genuinely practice order us a lot of interesting as well as of import things.

For those who are non economists, let’s live clear what the microfoundations projection inward macro is all about. The thought is that a macro model should live built upwards from a formal analysis of the behavior of private agents inward a consistent way. There may live simply a unmarried representative agent, or increasingly heterogeneous agents. So a typical periodical newspaper inward macro nowadays volition involve lots of optimisation yesteryear private agents equally a agency of deriving aggregate relationships.

Compare this to 2 choice ways of ‘doing macro’. The commencement goes to the other extreme: select a bunch of macro variables, as well as simply aspect at the historic human relationship betwixt them (a VAR). This uses minimal theory, as well as the focus is all nearly the yesteryear empirical interaction betwixt macro aggregates. The 2d would sit down inward betwixt the two. It powerfulness start off with aggregate macro relationships, as well as justify them with some eclectic mix of theory as well as empirics. You tin intend of IS/LM equally an is a lot better for it. We at nowadays sympathize to a greater extent than nearly the dynamics of inflation as well as employment organization cycles as well as then monetary policy is better. This shows that the microfoundations projection is progressive.

But simply because a methodology is progressive does non imply that it is the only proper agency to proceed. When I wrote that focusing on microfoundations tin distort the agency macroeconomists think, I was talking nearly myself equally much equally anyone else. I experience I pass likewise much fourth dimension thinking nearly microfoundations tricks, as well as reach insufficient attending to empirical evidence that should receive got much to a greater extent than influence on modelling choices. I don’t intend I tin simply blame anti-Keynesians for this: I would struggle New Keynesians also take away to live to a greater extent than pragmatic nearly what they do, as well as to a greater extent than tolerant of other ways of edifice macromodels.
