A country is attempting to measure its growth rate in technology. This is: possible to estimate using the growth accounting equation. impossible because you cannot directly observe technology. straightforward because technology is measured as the value of the new capital. not necessary because the growth rate in technology is the same as the growth rate in output.

A. This is: possible to estimate using the growth accounting equation.

Explanation:

Grow rate in technology is estimated using the following accounting equation stated in the Solow-Swan model:

Grow rate in technology = {Grow rate of productivity} - 1/3 {Grow rate of capital per hour of work}

This equation is derived from the predicting model that predicts a balanced-growth equilibrim economy. This estimated technical progress is refered to the disembodied technical progress, understood as the technology which allows increase the output from stated inputs.
