Right now chapter 4 only has the functional forms listed, but we should have more here.

Student Issue: Convexity Definition

Chapter 2

The definition of convexity on page 25 should include f(y) instead of just y at the end of the inequality.

Should look like:

f(λx + (1 − λ)y) ≤ λf(x) + (1 − λ)f(y)

instead of:

f(λx + (1 − λ)y) ≤ λf(x) + (1 − λ)y

One Page 33, "We will first establish this production function as The firm can then sell each unit of product at a"
There is a typo at "as The firm" -> the previous sentence ends abruptly at "as". I think there is missing text after "as". :)

Thanks for providing this resource, btw!

FOC Issue on Page 85. See attached pic.

Btw, thanks for making this textbook! It has legit been really helpful, and there are only a few minor typos. Thanks a lot Jimmy and Kevin! Y'all Rock :)

Right now we have a lot of theorems and properties that are stated, but we should link to them within the textbook.

Student Issue: Test issue 2

Overall

Second test issue with labels!

At around the top of the page, it says "p f '' (L) (L) < 0" but I think it's just supposed to say "p f '' (L) < 0".

Make sure our citations of papers are in a bibliography

Right now it says that the inequalities are reversed for price increases and decreases. The inequalities stay the same for the numerical values of each, but are reversed for the magnitude.

There are a bunch of blank recap sections that need to be filled in.

Student Issue: Convexity Definition

Chapter 2

Should be "It can be shown that if f is twice differentiable, then f is convex if and only if d2fdx2(x) >= 0 for any x" (should be greater than or equal to zero instead of less than zero?)

Note that this is to help the reader get used to various notations and also for aesthetic simplicity and clarity.

Should add some basic stuff like how tax policy affects firm choices in chapter 3.

This is just because of the Envelope Theorem. I don't think the individual steps here are actually correct:

Student Issue: Missing footnote

Chapter 1

Page 29, footnote 6 is missing

π = pf′(L∗) − (w + τ)L should be π = pf(L∗) − (w + τ)L

That is, first derivative of the production function should be replaced by the production function

The Lagrangian should be L = f(x) - \lambda (g(x) - c). We should make sure to standardize this throughout

A lot of these sections have papers that are probably relevant. They should be cited.

When giving the Envelope Theorem, there is a typo where the textbook says "F(x;,z)" instead of "F(x;z)", I think. :)

There are some functional forms and their corresponding coefficients of risk aversion listed in the lecture slides that are not in the textbook. Add these at some point.

Page 46, Tax Per Unit Sold: "That is, the effect of a change in the tax is exactly the negative of the effect of a change in price. This is because the firm only cares about the after-tax price, in which case a tax increase is essentially the same as a price increase."

I think this should be "...in which case a tax increase is essentially the same as a price decrease."

One page 40, when talking about the implicit function theorem, the book says "f is sufficiently "well-behaved"". What does "well-behaved" mean? :)

Student Issue: partial vs. total derivative

Chapter 3

Page 39. Why are the derivatives of L* with respect to p and w total and not partial derivatives?
