Q. Q(x,y)=x0,2y0,9 a) Essa fun\c{c}\~ao de produ\c{c}\~ao possui rendimentos crescentes, constantes ou decrescente de escala? Por qu\^e?
Determine type of returns: To determine the type of returns to scale, we need to sum the exponents of x and y in the production function Q(x,y)=x0.2y0.9.
Sum exponents: Sum the exponents: 0.2+0.9=1.1.
Check for increasing returns: Since the sum of the exponents is greater than 1 (1.1>1), the production function has increasing returns to scale.
