1. Phillips' stabilisation exercise and curve (2000 [1954], 151, Fig 16.11) examined the relationship between the rate of change of prices and the level of production (data limitations led to the use of two proxies: wage inflation and unemployment).

2. Concerns about colonisation and unbalanced development dates back (at least) to 1986:   

“At a symposium on the state of economics held in 1986, sponsored by the National Science Foundation, many participants put forth the view that economics as taught in graduate school had become too divorced from real world questions.” The resulting ‘Report of the Commission on Graduate Education in Economics’ discovered that “non-academic employers generally revealed fairly deep dissatisfaction with the training of new Ph. D’s employed by them”. There was an increasing worry that the grammar of mathematics had overtaken the substance of economics. Universities were producing too many intellectually disabled Ph. D.s: “idiots savants, skilled in technique but innocent of real economic issues” (Krueger 1991, 1035-1036, 1041, 1044-1045).

Any earlier examples of such concerns?

Subject: Re: [SHOE] MARK BLAUG AND BELIEF IN MODELS
 

The really big problem in using models by economists (especially
government's advisers) is that when they apply some findings flowing
from models' analysis they forget about assumptions and simplifications
being made during models building. The most famous examples in
macroeconomics is IS-LM model and so called 'Phillips Curve' (having
nothing common with original Phillips work, who was investigating
relationship between unemployment and wage rate, not, as it is commonly
presented (due to Samuelson imposition), between unemployment and
inflation). 

Long story about misusing formal, mathematical approach in economic
analysis, at least for one thick volume! 

Best wishes, 

Witold Kwasnicki

If you say, "He swims like a fish", you do not have to believe that he is a fish. The analogy is simply giving a representation and possible insight into how he swims. Similarly with theories, they may sometimes provide some insight or understanding of real world phenomena, but, as analogies, they cannot be considered as 'true' descriptions of the real world. Any belief that they are is misplaced.

Depending on the intended or justified use of a model, and on how good the model is, one is permitted or even advised to believe some parts or aspects of the model (insofar as its relations to its target are concerned). Models are far more complex creatures than what most practicing economists or historians or methodologists of economics have been able to clearly articulate. Mark Blaug's concern is one that troubled economists of the 19th century already.
