properties of technology
monotonic
free disposal
free lunch
convex, when tech production function is concave
TRS
technical rate of substitution
how much of one that you need relative to the other to keep output the same
-MPL/MPK=-aK/bL
returns to scale
increasing if t^a+b >1
constant if t^a+b=1
decreasing if t^a+b <1
monotonic
more input = more output
free disposal
(if too much is made you can throw it away)
free lunch
no input no output
