Cameron Murray — Corrupting Piketty in the 21st century

The media attention surrounding French economist Thomas Piketty’s new book Capital in the 21st Century is growing ever more fervent. Here are my two cents.

To me three things are clear to be about this book. First, it is a timely reminder that distribution of resources within society matters. This is especially important for an economics profession who has often ignored the issue and whose core analytical framework is a completely inappropriate tool for its analysis. ["Robert Lucas wrote in an essay in 2004: "Of the tendencies that are harmful to sound economics, the most seductive, and in my opinion the most poisonous, is to focus on questions of distribution.'" — Paul Krugman.]

Second, and this is quite a surprise, the mainstream economics profession seems to be rather accepting of the book, which, when I read it, seemed to make the claim that most of their scholarly methods are flawed and that the economics profession knows very little about the more important elements of social organisation. While on the surface this appears to be a mature response by the profession to valid criticisms, I fear that the profession will corrupt the message of the book and will unfortunately not have the impact on improving economic scholarship that it seems intended to have.

Third, and this is my one personal gripe, the book fails to acknowledge the many social processes studied by sociologists and even ecologists that have been used to explain unequal outcomes in a wide variety of settings. For example, the process of preferential attachment is fundamental to producing the unequal distribution of the success of artists, musicians and even, ironically, authors. Such a process can not only explain the broader inequalities in terms of access to resources (income and wealth), but also the inequality of book success, where Piketty finds himself in the top 1% of economics authors (and there really is no shortage of books covering similar topics recently, for example here, here,here and here).

I want to now explore these latter two point in more detail.
