São Paulo – Em um lado do ringue ninguém menos que John Maynard Keynes - economista britânico famoso defensor do estado intervencionista - e, no outro, Friedrich Hayek – economista austríaco pensador do livre mercado.

O encontro inusitado acontece em um vídeo produzido e divulgado hoje pela Econstories.tv. O filme de 10 minutos simula um embate das ideias dos dois economistas em formato de um rap durante uma audiência no Congresso americano para debater O impacto dos gastos governamentais na economia.

O vídeo, produzido pelo economista da George Mason University, Russ Roberts, e pelo produtor diretor John Papola, traz as teorias econômicas de ambos para o momento atual no qual o país vive. A decisão do governo americano de salvar bancos e aplicar os afrouxamentos quantitativos (compra de títulos que expandiu a base monetária) é lembrada.

De acordo com a National Bureau Economic Research, a grande recessão encerrou no final de 2009, apesar disso, o desemprego continua em níveis altos (8,8%) nos EUA. É um prato cheio para Hayek questionar a eficácia da política intervencionista defendida por Keynes.

Nós poderíamos ter ido melhor caso tivéssemos gasto mais. É uma pena que isso só acontece quando há uma Guerra Mundial. Você pode criticar tudo que quiser sobre estatísticas e regressões, mas você nega que a Segunda Guerra Mundial abreviou a Depressão?, diz Keynes.

A resposta de Hayek é ríspida: Postos de trabalho são os meios, não o fim em si. As pessoas trabalham para viver melhor, para colocar comida nas prateleiras. Crescimento real é produzir o que as pessoas demandam. E provoca: Se todo trabalhador fosse recrutado para o exército, teríamos um pleno emprego e nada para comer.

Keynes, então, indaga: Então o que você faria para ajudar os desempregados? Quando estamos em uma bagunça, você nos faria esperar? Sem fazer nada até os mercados se equilibrarem?.

Não deveríamos repetir o que nos criou problemas. Eu quero um crescimento real e não uma série de bolhas. Vamos parar de ajudar os perdedores e deixar os preços trabalharem. Se não tentarmos guiá-los então eles não ficarão frenéticos, golpeia Hayek.

No filme, Keynes beija a lona e parece ter perdido a luta de ideias. Mesmo assim, o juiz dá a vitória para o economista britânico. Foi o caminho escolhido pelos EUA.

Fight of the Century Lyrics.

KEYNES

Here we are… peace out! great recession
thanks to me, as you see, we’re not in a depression
Recovery, destiny if you follow my lesson
Lord Keynes, here I come, line up for the procession

HAYEK
We brought out the shovels but we’re still in a ditch…
And still digging. don’t you think that it’s time for a switch…
From that hair of the dog. Friend, the party is over.
The long run is here. It’s time to get sober!

KEYNES
Are you kidding? my cure works perfectly fine…
have a look, the great recession ended back in ’09.
Surely, I deserve credit. Things would have been worse
All the estimates prove it—I’ll quote chapter and verse

HAYEK
Econometricians, they’re ever so pious
Are they doing real science or confirming their bias?
Their Keynesian models are tidy and neat
But that top down approach is a fatal conceit

REFRAIN
Which way should we choose?
more bottom up or more top down
…the fight continues…
Keynes and Hayek’s second round

it’s time to weigh in…
more from the top or from the ground
…lets listen to the greats
Keynes and Hayek throwing down

KEYNES
we could have done better, had we only spent more
Too bad that only happens when there’s a World War
You can carp all you want about stats and regression
Do you deny World War II cut short the Depression?

HAYEK
Wow. One data point and you’re jumping for joy
the Last time I checked, wars only destroy
There was no multiplier, consumption just shrank
As we used scarce resources for every new tank

Pretty perverse to call that prosperity
Rationed meat, Rationed butter… a life of austerity
When that war spending ended your friends cried disaster
yet the economy thrived and grew ever faster

KEYNES
You too only see what you want to see
The spending on war clearly goosed GDP
Unemployment was over, almost down to zero
That’s why I’m the master, that’s why I’m the hero

HAYEK
Creating employment’s a straigtforward craft
When the nation’s at war, and there’s a draft
If every worker was staffed in the army and fleet
We’d be at full employment with nothing to eat

REFRAIN

HAYEK
jobs are the means, not the ends in themselves
people work to live better, to put food on the shelves
real growth means production of what people demand
That’s entrepreneurship not your central plan

KEYNES
My solution is simple and easy to handle..
its spending that matters, why’s that such a scandal?
The money sloshes through the pipes and the sluices
revitalizing the economy’s juices

it’s just like an engine that’s stalled and gone dark
To bring it to life, we need a quick spark
Spending’s the life blood that gets the flow going
Where it goes doesn’t matter, just get spending flowing

HAYEK
You see slack in some sectors as a general glut
But some sectors are healthy, and some in a rut
So spending’s not free – that’s the heart of the matter
too much is wasted as cronies get fatter.

The economy’s not a car, there’s no engine to stall
no expert can fix it, there’s no it at all.
The economy’s us, we don’t need a mechanic
Put away the wrenches, the economy’s organic

REFRAIN

KEYNES
so what would you do to help those unemployed?
this is the question you seem to avoid
when we’re in a mess, would you just have us wait?
Doing nothing until markets equil-i-brate?

HAYEK
I don’t want to do nothing, there’s plenty to do
The question I ponder is who plans for who?
Do I plan for myself or leave it to you?
I want plans by the many and not by the few.

We shouldn’t repeat what created our troubles
I want real growth not just a series of bubbles
Let’s stop bailing out losers and let prices work
If we don’t try to steer them they won’t go berserk

KEYNES
Come on, Are you kidding? Don’t Wall Street’s gyrations
Challenge your world view of self-regulation?
Even you must admit that the lesson we’ve learned
Is more oversight’s needed or else we’ll get burned

HAYEK
Oversight? The government’s long been in bed
With the Wall Street execs and the firms that they’ve led
Prosperity’s all about profit and loss
When you bail out the losers there’s no end to the cost

the lesson I’ve learned? It’s how little we know,
the world is complex, not some circular flow
the economy’s not a class you can master in college
to think otherwise is the pretense of knowledge

REFRAIN

KEYNES
You get on your high horse and you’re off to the races
I look at the world on a case by case basis
When people are suffering I roll up my sleeves
And do what I can to cure our disease

The future’s uncertain, our outlooks are frail
Thats why free markets are so prone to fail
In a volatile world we need more discretion
So state intervention can counter depression

HAYEK
People aren’t chessmen you can move on a board
at your whim–their dreams and desires ignored
With political incentives, discretion’s a joke
The dials you’re twisting… are just mirrors and smoke

the market’s a process where we can discover
the most valuable ways to serve one another
we need stable rules and real market prices
so prosperity emerges and cuts short the crisis

REFRAIN
Which way should we choose?
more bottom up or more top down
the fight continues…
Keynes and Hayek’s second round

it’s time to weigh in…
more from the top or from ground
…lets listen to the greats
Keynes and Hayek throwing down
