2. Of or constituting an educational method in which learning takes place through discoveries that result from investigations made by the student.

The economy is being held back not by exogenous "headwinds" but instead, since interest rates in the past (initially, in the second half of the 1990s) were too low and too much spending was brought forward from the future, is being held back by the endogenous working of the Euler equation for consumption, which says that consumption will be on a downward path, relative to income, if the relevant interest rate is below the rate of time preference (and, heuristically, there is reason to believe that this is the case).
