Numerical Results

The table below shows the final numerical characteristics and indicators of inequality for each of the seven fictitious Chancy Islands as well as Skewed Island in Year 0. Click on the table to see a printable, full-screen version. Or view it as a GoogleDoc spreadsheet.

Table Notes

A yellow background indicates the input parameters that have changed from the previous column.

Flat Island has a tan background to indicate that it is different from the other islands since all households there have identical and uniform luck.

Skewed Island has a light violent background to indicate that, unlike the other islands in which all of the households have the same initial wealth of $250,000, the 500 households on Skewed Island have variable and widely skewed initial wealth that mimics the United States in 2016 as calculated in this spreadsheet.

Skewed Island in Year 0 is also shown here (with a green background).

Here are definitions of the main measures of wealth inequality.

Graphs

Below is a graph of Gini Coefficients for the seven islands in Year 50, plus (in green) the Gini Coefficient for Skewed Island in Year 0. Note that Flat Island has perfect equality, so its Gini Coefficient is 0.

The graph below shows the percent of total wealth[1] held by each quintile of the households in Year 50 for the seven islands and Skewed Island in Year 0.
