[…] except that I do not value tremendously [Krugman’s] own theoretical perspective. If you look at the way he understands the world, […] it is a single-sector economy model, […] everything he talks about is couched in terms of the IS-LM model that undergraduates learn in macroeconomics 101 […] it is a single-commodity universe. It is as if the macroeconomy produces only one good, and that one good is produced by one capital good. So, in fact it’s the same commodity and capital good.
So, it’s like a corn model, like David Ricardo’s theory […] of a very simple world in which there’s only one commodity (it’s corn), and corn can be eaten (it’s a consumption good) or it can be invested (you save it to use it as seeds […], that’s a capital good). And in that kind of world […], returns to capital are not difficult to envisage. […] If you have a fist full of corn seeds, you know how much corn you’ll get out of it when you cultivate it. […]
There’s no money in any of these economic models. […] If you introduce money to any of these models, those models explode, so they become indeterminate, in other words anything goes, any price, any quantities possible […] it’s a useless model […] So, the fact that Paul Krugman likes Piketty’s analysis [Piketty’s 2013 best-seller Capital in the Twenty First Century] is not a great surprise to me, because in the end, their Neoclassical background is a [..] shared one.
The Neoclassical school has some unique strengths. Its insistence on breaking phenomena down to the individual level gives it a high degree of precision and logical clarity [but you can have high precision AND low accuracy, meaning your results have low variability but are still very inaccurate!]. It is also versatile. It may be very difficult for someone to be a ‘right-wing’ Marxist or a ‘left-wing’ Austrian [this is a messy example until we clarify our definitions for “left” vs. “right”], but there are many ‘left-wing’ Neoclassical economists, such as Joseph Stiglitz and Paul Krugman, as well as very ‘right-wing’ ones, like James Buchanan and Gary Becker. To exaggerate only slightly, if you are clever enough, you can justify any government policy, any corporate strategy, or any individual action with the help of Neoclassical economics. [I don’t think mental gymnastics should count as a strength, especially when judging theory. Who needs theory when you can just make things up?]--More critically, Steve Keen (who had infamous debates with Krugman) critiques how Neoclassical economics has neutered other schools it encounters. The crucial example is Neoclassical vs. Keynesian; Keen critiques the hybrid “Neo-Keynesian”/“Neoclassical-Keynesian synthesis” as a Neoclassical debauchery, in contrast to Post Keynesian. See Keen’s The New Economics: A Manifesto.
Paul Krugman is a colleague, an academic economist of substance, and someone who has made a huge contribution especially during the years of the Bush [Junior, the painter] administration when he used his New York Times column to single-handedly confront a great deal of falsities and toxic economic views and policies. So, this is my preface to saying effectively that I have a great deal of admiration for Paul Krugman, his contribution to public debates so far…--So, we can return to Chang for a direct critique of the politics of Krugman’s economics:
[…] now, the difference between Krugman and Piketty is that Krugman is a sincere man, and a thoroughly progressive political economist. So, he uses his IS-LM simplistic model in order to say and do good things. So, when he talks about the Eurozone, […] Wall Street, […] the Trickle-down effect, in spite of his simplistic modeling he says some excellent things and very useful interventions he makes in the political arena. My concern with professor Piketty is that he is much shiftier and far less interested in changing the world in important ways than Paul Krugman is.
Neoclassical economics is too accepting of the status quo. In analysing individual choices, it accepts as given the underlying social structure – the distribution of money and power, if you will. This makes it look at only choices that are possible without fundamental social changes. For example, many Neoclassical economists, even the ‘liberal’ Paul Krugman, argue that we should not criticize low-wage factory jobs in poor countries because the alternative may be no job at all. This is true, if we take the underlying socio-economic structure as given. However, once we are willing to change the structure itself, there are a lot of alternatives to those low-wage jobs. With new labour laws that strengthen worker rights, land reform that reduces the supply of cheap labour to factories (as more people stay in the countryside) or industrial policies that create high-skilled jobs, the choice for workers can be between low-wage jobs and higher-wage ones, rather than between low-wage jobs and no jobs.…Chang is particularly sensitive to global inequalities given his childhood experiences with South Korea’s rapid industrialization (we should also consider the preceding land reforms). In my books, someone like Krugman tepidly supporting welfare redistribution at home in the imperial core (U.S.) while condemning the Global South periphery to imperialist super-exploitation…this is not “thoroughly progressive”, given the U.S.’s global influence (and thus responsibility/culpability of its intellectuals).
I found Chapter 8, Politics of Inequality, the most informative. The chapter outlines how George W. Bush and Dick Cheney came to lead the country and how it's tied to William F. Buckley defending the right of the South to prevent blacks from voting— the white community is so entitled because it is, for the time being, the advanced race. And how they praised Generalissimo Francisco Franco, who overthrew a democratically elected government in the name of church and property.
Another passage that caught my attention was, Latter-day haiographers have portrayed Ronald Reagan as a paragon of high-minded conservative principles, but he was nothing of the sort. His early political successes were based on appeals to cultural and sexual anxieties, playing on the fear of communism, and, above all, tacit exploitation of white backlash against the civil rights movement and its consequences.
For me, there was so much new information in The Conscience of a Liberal that it was mind boggling!
The Conscience of A Liberal was well written, flowed well, and an easy and informative read.
