Summary f(X) f(x) X Standard production economics analysis begins with the production function y=f(x) where y is output and x is input
Summary Standard production economics analysis begins with the production function y =f (x) where y is output and x is input
1. Defining the production technology and technical efficiency All feasible input-output vector relationships are described by the graph of the production technology or production possibilities set, PT such that PT=i(y, x): x can produce y j

Input and output sets 只能能共影与 The input(output)sets of the production technology which describe the sets of all input(output) vectors that are feasible for each output(input) vector y(x), are defined as y)={x:(y,x)∈PT} 72 P(x)={y:(y,x)∈PT 73
Input and output sets The input (output) sets of the production technology, which describe the sets of all input (output) vectors that are feasible for each output (input) vector y (x), are defined as L(y)=｛x: (y, x) ∈PT｝ 7.2 P(x)=｛y: (y, x) ∈PT｝ 7.3
