2.6 (Micro) PES for primary commodities vs. manufactured goods: PES: Elastic vs. inelastic: IB Econ

Video tutorial for IB Economics students illustrating how to draw and analyze (explain) why the price elasticity of supply (PES) for primary commodities is inelastic, and why manufactured goods is elastic.
The video also goes over the following determinants of PES:
1. Length of time
2. Mobility of factors of production
3. Unused capacity
4. Ability to store stock
5. Rate at which cost increase
Note:
IB Econ Paper analysis of the economic model at time 12:00.

Analysis: Supply of primary commodities (inputs) and manufactured goods (outputs)
* Graph A: Supply of coffee beans (inputs)
* Graph B: Supply of Nespresso capsules (outputs)
* X-axis measures quantity supplied
* Y-axis measures price
*PES = %∆Qs divided by the %∆P
* Graph A: Supply of coffee beans (inputs)
* Upward sloping supply curve (S1) in accordance with the law of supply
* S1 has a PES less than 1 (inelastic) as a result of the determinant of length of time (3 to 4 years for newly planted coffee trees to bear fruit - one harvest a year)
* Graph B: Supply of Nespresso capsules (outputs)
* S2 has a PES greater than 1 (elastic) as a result of the determinants of mobility of factors of production (Nespresso able to source coffee beans from 25 million coffee farmers), unused capacity, and ability to store stock.
* Graph A
* Price of P1 with Qs at Q1
* Price increases from P1 to P2 thus Qs increases from Q1 to Q2
* %∆P is greater than the %∆Qs
* PES is less than 1
* For example, if PES=0.5, then for every 1% increase in price, Qs increases by 0.5% (length of time needed to grow more coffee beans)
* Graph B
* Price of P1 with Qs at Q1
* Price increases from P1 to P2 thus Qs increases from Q1 to Q2
* %∆Qs is greater than the %∆QP
* PES is greater than 1
* For example, if PES=4.5, then for every 1% increase in price, Qs increases by 4.5% as a result of the determinants of mobility of factors of production (Nespresso able to source coffee beans from 25 million coffee farmers), unused capacity, and ability to store stock
