HC2: Economic Theory, a refresher (6 feb)
Basic economic concepts
Opportunity costs
= Costs incurred by missing out choosing an alternative.
Trade-offs
= You need to balance two likable things, or two unlikable things.
Utility function
= typically has consumption of one or more goods as input. And has the utility of a consumer
as output. Consumers always want to maximize utility.
Producer Theory
Profits (π)
= Revenue – costs
= p*q - C(q)
Δ𝐶(𝑞)
Costs C(q) → Marginal costs = Δq
𝐶(𝑞)
→ Average costs = 𝑞
→ Variable costs = non-fixed costs (these derive to 0)
→ Sunk costs = expenses that are incurred anyway. Need not to be considered.
Optimal pricing: π(q)’ = 0 → mr(q) = mc(q)
Thus, producers need to set the quantity such that the marginal revenue (price,
in linear functions) is equal to the marginal costs (typically increases)
Welfare Analysis
Competitive market → Price is given. Producers merely set quantity
Thus, marginal revenue is [pq]’=p
Assumption: In the long run, no producer can make profit in a competitive market, because
in case of profits, producers will enter, and in case of losses, producers will drop out.
Monopoly → One producer can determine both price and quantity
Price follows quantity. P(q) is the price.
