Does wealth follow a normal distribution?
The emerging consensus in the empirical econophysics literature is that the bulk of income and wealth distributions seems to follow the log-normal or gamma distributions, while the upper tail follows power- law distribution.
Why is there so much wealth inequality in the US?
Economic inequality is a result of difference in income. Factors that contribute to this gap in wages are things such as level of education, labor market demand and supply, gender differences, growth in technology, and personal abilities.
What is meant by Pareto optimality?
