If mp is above ap

Induced innovation hypothesis
Increased populations, trigger increased demand for agriculture goods. Land scarcity results I ag innovation and increased sustainability.
Right before industrialization, birth rates are stable and a lil higher than death rates.
Death rates fall dramatically but birth rates stay the same causing large population growth.
Longer life expectancy and birth rates fall below the declining death rates.
Theory of demographic transition.
Reduction in population growth might cause higher standard of living.
One source of market failure.
Artificially lowers the cost of children.
Specific bodies of mineral bearing material who’s location quality and quantity are known from geological evidence supported by engineering measurements
Material for which quantity and quality estimates are within a margin of error of less than 20% from geologically well-known sample sites
Material for which quantity and quality have been estimated partly from sample analysis and partly from reasonable geological projections
Material in unexplored extensions of demonstrated resource based on geological projections
On specific bodies of mineral bearing material surmised to exist on the basis of broad geological knowledge and theory
undiscovered materials reasonably expected to exist in a known mining district under known geological conditions
Undiscovered materials that may occur in either known types of deposits and favorable geological settings were no discoveries have been made or in yet unknown types of deposit that remain to be recognized
Microeconomic theory of fertility
Begins at the viewpoint…children are consumer durables… and the demand for them will be downward sloping.
