Question

What are some of the competing theories to explain why humans age and aging creates a post reproductive period. How does this life course give humans an evolutionary advantage? How does economics lend to biology in these models? Which seems most plausible? What does the model imply for present day time preferences? (How does biology lend to economics?

Answer 1

Human Age or the Aging is the process where a person grows up and it involves changing a person's appearance, characteristics, and increase in experience level. This process is unavoidable.

Many theories explain humans age and aging creates a post-reproductive period. Some of them are programmed theories, damage, or error theories activity theory, disengagement theory.

Programmed Theory is that theory which follows a biological timetable. It is regulated by a change in gene expression.

Damage or Error Theory is that theory that emphasizes environmental assaults to living organisms.

Activity theory is the normal theory of Aging. Its conceptual Framework is Activity which is change as per age changes.

The disengagement theory is the theory that occurs naturally. In this theory, an Aging person decreases interaction with society.

Life-course give humans an Evolutionary Advantage.

1. Prevent from Heridotory Diseases

2.Increases Power of Thinking

3.With Growing of Age it increases the power of Understanding among people.

4.Increases Work Ability

5.With Increases of Age it also gives various Experience which gives benefit in taking the right decision.

How does economics lend to biology in these models?

Economics is a social science. Economics and Biology are closely related to each other. As to find out the best utilization of the human resource, their ability to work, Power of thing Bioeconomics help in determining the best utilization of these biological resources. Bioeconomics is the progressive branch that integrates the activity of economics and biology intending to create theories.

These theories are created in Bioeconomics to help in determining the behavior of a human in economic conditions. It explaining economic events using a biological basis.

Some Bioeconomics models are Bioeconomics (fisheries), Bioeconomics (biophysical), Biological economics, Bioeconomics Theory of Nicholas Georgescu-Roegen.

The most plausible model is Biological Economics Models which study relationships between human biology and economics.

What does the model imply for present day time preferences?

In present-day time preferences, this model studies the relationship between human biology and economics and study of the dynamics of living resources using economic models and the study of economic systems applying the laws of thermodynamics.
