Definition of Capital-Augmenting: Capital-augmenting is one of the ways in which an effectiveness variable could be included in a production function in a Solow model. If effectiveness A is multiplied by capital K but not by labor L, then we say the effectiveness variable is capital-augmenting.

For example, in the model of output Y where Y=(AK)^aL^1-a the effectiveness variable A is capital-augmenting but in the model Y=AK^aL^1-a it is not.

Another example would be a capital utilization variable as measured say by electricity usage. (E.g., as in Eichenbaum).

An example: in the context of a railroad, automatic railroad signaling, track-switching, and car-coupling devices are capital-augmenting. From Moses Abramovitz and Paul A. David, 1996.
