Lonergan on economics: For a New Political Economy

After having gone through chapters 5-8 of Shute, I felt I had to get some matters clear, especially regarding the trade cycle, so I began dipping into Lonergan himself, For a New Political Economy. Delighted that I am able to more or less keep up with him, and he is certainly much clearer than his interpreters, at least, that is my first impression. But then having read the interpretations is already to be factored into the 'clarity' and 'ease' with which the original is opening up....

I wrote something to Viplav Kambli about a piece on inflation that he sent me yesterday - advice on how to invest at a time when inflation cuts into fixed deposits. He wrote back briefly, and I wrote back trying to outline how Lonergan might understand inflation as not primarily an economic phenomenon, but as a phenomenon linked to the production process. I realized in the course of writing that there is much more that I have to become clear about.

I have to keep in mind, first of all, Lonergan's use of the method of approximation. The pure cycle, with its 3 or 4 phases (capitalist, materialist, cultural, stationary) is a first approximation. The trade cycle is the beginning of a second approximation: what happens when pure surplus income is misunderstood by capitalists, or by governments, or by labour and labour unions. In his economics manuscripts, Lonergan does not go into the third step of the approximation, the step of healing or redemption: that is reserved for his later work, and is necessarily theological in his perspective.

But it is a nice feeling when, going through FNPE, the famous baseball diamond diagram becomes clearer....

One of the questions that I have to tackle: why the theorem of continuity? I think Lonergan says that this theorem is valid, as elaborated in chapter 5, only in the static phase. In chapter 6 he generalizes it. But: what is the point of this theorem?

Another question: why the normative proportion? And what is the significance of the consequences drawn? “It follows that the profit motive is subject to decreasing returns.” [FNPE 54.]

At any rate, Lonergan clearly critiques the profit motive of capitalism: it works very well in the capitalist phase; it works less and less well in the materialist phase when surplus ratio is decreasing; it has no leverage at all in the static phase when S is zero; and it works less well in each successive stage of economic development.
