Technology and Demography
Economics is an interesting science. For me, one of its appeals is its dual nature; it makes use of both sides of the brain. In some ways, it has elements of a hard science, mathematical models, empirical data, etc. However, at its core, it is a social science. We can see an example of this in the concept of value. It can be both intangible and tangible. The value of a human life is subjective.
