The recent book by Jesse Norman simply entitled “Adam Smith” is a pleasure to read. There are of course innumerable books on the founder of the political economy, so why another one? Norman’s book is directed toward that, at times elusive, general educated reader, and has, in my opinion, three objectives: (i) to situate Adam Smith in his time, both intellectually and politically, (ii) to argue that there is a remarkable consistency between the Adam Smith of the Theory of Moral Sentiments,...

More philosophy of economics, or foundations, if you prefer. Good read if you are into this. It runes along the lines of what amateur economist and working physicist Jason Smith has been saying about foundations.J. W.

Another good one on foundations of science and economics, specifically macroeconomics — if you are into this sort of thing. These papers also fail to make any empirical predictions or really engage with data at all. I get the impression that people aren't actually interested in making predictions or an actual scientific approach to macro- or micro-economics, but rather in simply using science as a rhetorical device....

I was part of an epic Twitter thread yesterday, initially drawn in to a conversation about whether the word "mainstream" (vs "heterodox") was used in natural sciences (to which I said: not really, but the concept exists). There was one sub-thread that asked a question that is really more a history of science question (I am not a historian of science, so this is my own distillation of others' work as well a couple of my undergrad research papers). Useful relative to philosophy of science...

The other day, Rethinking Economics and the New Weather Institute published "33 theses" and metaphorically nailed them to the doors of the London School of Economics. They're re-published here. I think the "Protestant Reformation" metaphor they're going for is definitely appropriate: they're aiming to replace "neoclassical economics" — the Roman Catholic dogma in this metaphor — with a a pluralistic set of different dogmas — the various dogmas of the Protestant denominations (Lutheran,...

Math is purely formal, involving the relation of signs based on formation and transformation rules. Signs are given significance based on definitions. Math is applicable to the world through science to the degree that the definitions are amenable to measurement and the model assumptions approximate real world conditions (objects in relation to others) and events (patterned changes in these relations). Methodological choices determine the scope and scale of the model, which in turn...

More thoughts on economic methodology. First a framework is needed and then theories can be constructed and tested in that framework. The simplest frame and most economical theory that explains the data sufficiently to be useful is preferred.A framework involving complexity is not necessarily better than one that doesn't as long as it gets the job done.Smith observes that theories constructed within the conventional framework that conventional economists presume is not getting the job of...

On reductionism.This is also the case in philosophy where different methods attempt to exclude other methods by reducing the debate to a lower level of data, e.g, sense data only, or lower order of abstraction, e.g., all abstraction must be reducible to first order. These methodological assumptions reduce justification to observations of objects. For example, David Hume used philosophical reduction to sense data to exclude causality, arguing that causality is nothin more than observation of...
