Economic Production Functions and Cost Relationships
Key Relationships in Production and Costs
APL and AVC Relationship
If APL (Average Product of Labor) is growing, AVC (Average Variable Cost) and ATC (Average Total Cost) are decreasing. There is an inverse relationship between APL and AVC (and ATC). Specifically, you can check that:
AVC = w / APL
MC = w / MPL
Example Calculation: AVC = 2 / (0.25L) = 2 / (0.25 · 2Q0.5) = 4 / Q0.5
MPL and MC Relationship
If MPL (Marginal Product of Labor) is growing, MC (Marginal Cost) is decreasing. There is an inverse

Genes and Genomes
Every cell contains a complete set of genetic instructions—the genome—encoded in DNA and organized into genes packaged on chromosomes. A gene is a specific DNA sequence that encodes a functional product (usually a protein or an RNA). Genetic variation (mutations) underlies phenotypic differences, while environmental factors also contribute to traits.
