Content

[x] We can refer to concepts like 'steady state' and 'global stability' using hyperlinks to the Dynamics lecture.
[x] 45 -> $45 \degree$ in graph.
[x] Add more details on how to get (21.4) by adding a link to how to solve it.

Some further comments

Content

[x] ~~21.1 - remove the term homogeneous as the function is non-linear~~
[ ] 21.1 - State that 1-δ is an assumption of the model rather than outcome
[ ] 21.1 - Define $\alpha$, and $\rho$
[ ] 21.1 - Clarify the derivation of $k_{t+1}$ by write out an extra step of dividing both step by L
[ ] 21.2 - Include a comparative study to see changes in the shape of the model as A or K changes
[ ] 21.3 - Might consider giving some further exploitation for the diagram in this section
[ ] Potentially changing the order of 21. The Solow-Swan Growth Model and 22. Dynamics in One Dimension

@Jiarui-ZH Hi Jiarui, I have a simple question. Why remove the term 'homogeneous' if the function is non-linear? I believe homogeneity is independent of linearity, and the 'homogeneous of degree one' here refers to 'constant returns to scale'.

Jiarui-ZH commented 2 months ago

Apologies for the confusion, I might have missed interpreter the point mentioned in the discussion, @pgrosser1 perhaps you can share your notes for this section?

pgrosser1 commented 2 months ago

Sorry I didn't see this earlier @Jiarui-ZH @SylviaZhaooo. I believe that comment was referring to a discussion between John and I about the difference between linearity and homogeneity of degree one - it wasn't meant to be an edit suggestion.

I will also clarify that the fifth point was referring to adding a bifurcation diagram for the behaviour of the fixed points as some control parameter (either A or K) is changed.

I think there was also an edit suggestion missed where I suggested that we add a mathematical description of fixed point stability (ie. in corresponding it with the fact that the derivative of the function evaluated at the fixed point is negative).
