April 2020Does EdTech Substitute for Traditional Learning? Experimental Estimates of the Educational Production Function
with Eric Bettinger, Robert W. Fairlie, Anastasia Kapuza, Prashant Loyalka, Andrey Zakharov: w26967
Experimental studies rarely consider the shape and nature of the education production function, which is useful for deriving optimal levels of input substitution in increasingly resource constrained environments. Because of the rapid expansion of EdTech as a substitute for traditional learning around the world and against the backdrop of full-scale temporary substitution due to the coronavirus pandemic, we explore the educational production function by using a large randomized controlled trial that varies dosage of computer-assisted learning (CAL) as a substitute for traditional learning. Results show production is concave in CAL. Moving from zero to a low level of CAL, the marginal rate of technical substitution (MRTS) of CAL for traditional learning is greater than one. Moving from a low...
