[HumphreyYang]

Suggestions by @longye-tian

Code

• Remove the grid.
• Change the legend for the Laffer curve plot to "Laffer curve". Also, use default colors in matplotlib.

Content

• Bold face is reserved for definitions and italics are used for emphases.
• Only the first word in the title should be capitalized.
• Migrate some of "This lecture studies" to "We study ...".
• Maintain consistent use of bar and overline.
• (28.3) repeats (28.2). Consider removing (28.3) and adjusting the links to (28.2) if (28.3) is removed.
• Define all the notations like $\pi$ and $m$.
• "limiting values exists" -> exist
• "...that studies a linear version of the model in this lecture`" -> "that studies a linear version of the model in this lecture."
• Give a theoretical explanation for the patterns in Figure 28.2.
• In Equation (28.6) we have $x: x \ge 0$. Remove "x:", and put a curly bracket covering the equation after max to indicate the scope of max.

@jstac the last remaining item in this issue is

• Give a theoretical explanation for the patterns in Figure 28.2.

Do you think this is necessary? There is some discussion around the graph.
