Elisabetta Lalumera posted a comment with an interesting question:

"What is cognitive economy?  Sometimes philosophers and psychologists evaluate proposals on the graounds that they fare well/bad at cognitive economy (e.g. on-the-fly concept views, like Barsalou's, would avoid the storage cost of concepts in semantic memory, etc.)."

"Any suggestion about what to look at to see whether cognitive economy is a myth or not?"
