That theory needs a rapid qualification.
In the end all this theory needs some empirical ballast.
In our age, to be sure, anyone reviving critical theory needs a sense of irony.
Fascinating, possibly a new direction, but as the speaker himself said, the theory needs to make some experimentally testable predictions.
Rather they engaged in "exploit": challenging and creative activities such as writing, philanthropy and debating.Veblen's theory needs updating, according to a recent paper from researchers at Oxford University*.
By 1900 (admittedly after several revolutions and wars) they were 11 times larger.But growing inequality in developing countries leaves Ricardo's disciples befuddled and suggests the theory needs updating.
Taking switching costs into account immediately narrows the extent of plausible market failures.The new theory needs to be qualified in another way, too.
In practice, though, it seems to be active only in cancerous cells—suggesting that the theory needs rewriting.Such rewriting is exactly the sort of task that a Human Epigenome Project could help with.
They chose to study aftershocks because there are thousands of them, and their statistical theory needs lots of data to work properly.Sure enough, aftershocks were found to congregate in the regions of increased stress as predicted by the model, while in the regions of reduced stress (called "stress shadows") the number of aftershocks was very small.
Jannini and others point out, however, that this theory needs more confirmation.
Salmon (1989) argues that Kaplan's theory needs to be amended so as to make contents eternal.
