## Long descriptions for some figures in Game Theory and Ethics

### Figure 2 description

• Laura (root node)
• $$(2,2)$$ (node; line to it labeled P)
• $$(0,3)$$ (node; line to it labeled A)

### Figure 3 description

A decision tree

• Claudia (root node)
• Laura (node; line to it labeled P)
• $$(2,2)$$ (node; line to it labeled P)
• $$(0,3)$$ (node; line to it labeled A)
• Laura (node; line to it labeled A)
• $$(3,0)$$ (node; line to it labeled P)
• $$(1,1)$$ (node; line to it labeled A)

### Figure 4 description

A decision tree

• Claudia (root node)
• Laura (node; line to it labeled P)
• $$(2,2)$$ (node; line to it labeled P)
• $$(0,{3-\gamma})$$ (node; line to it labeled A)
• Laura (node; line to it labeled A)
• $$(3,0)$$ (node; line to it labeled P)
• $$(1,1)$$ (node; line to it labeled A)

### Figure 9 description

A x-y graph with a labeled center of $$(0,0)$$. on it is a green shaded triangle region with vertices at $$(0,1),$$ $$(1,0),$$ and $$(-1,-1)$$ [also labeled ‘Nonagreement Point’]. The labeled point $$(\frac{1}{2},\frac{1}{2})$$ is on the line between the first and second points.

### Figure 11 description

A x-y graph with x and y axes ranging from 0 to 1. On it is a green shaded quadrilateral region with vertices $$(0, \frac{1}{9})$$, $$(\frac{1}{2},1)$$, $$(1, \frac{2}{9})$$, and $$(\frac{1}{6},;0)$$. On the line connecting the second and third points are three more points each also labeled:

• $$(0.536,0.944)$$ Nash
• $$(0.652,0.763)$$ proportional
• $$(0.682,0.717)$$ maximin proportionate gain

### Figure 12 description

An equilateral triangle with vertices labeled counterclockwise:

• $$e_1(D)$$
• $$e_2(M)$$
• $$e_3(H)$$

A path is drawn connecting a sequence of points starting from a point towards the middle of the triangle, heading down and curving towards the towards the second vertex $$e_2(M)$$.

### Figure 13 description

Same equilateral triangle as Figure 12 with vertices labeled counterclockwise:

• $$e_1(D)$$
• $$e_2(M)$$
• $$e_3(H)$$

The interior of the triangle has 200 curves starting at various points around the interior of the triangle. Most of these individual curves bend towards a single central curve that runs from about half way between the first and third vertices and ultimately ends converges to the second vertex. But a few of these curves, with starting points especially close to the first or third vertex bend toward that same central curve but converge to a point about half way between the first and third vertex.

### Figure 14 description

Same equilateral triangle as Figure 12 with vertices labeled counterclockwise:

• $$e_1(D)$$
• $$e_2(M)$$
• $$e_3(H)$$

The interior of the triangle has 200 curves starting at various points around the interior of the triangle. All of the individual curves bend towards a single central curve that runs from about half way between the first and third vertices and ultimately converges to the second vertex.

### Figure 15 descriptions

Each of the figures 15a through 15d is a grid of squares $$20\times 20$$ with each square either blue (one agent), red (the other agent), or white (empty). Figure 15a has the colors the most mingled; figure 15b has some clumping of colors, figure 15c some more clumping of colors (4 red regions, 5 blue regions), and figure 15d the most (2 red regions, 3 blue regions).
