,Microeconomics 2 summary
Lecture week 1
Good market outcome = maximizes welfare. Achieved by leaving the market alone. Could lead to
inefficient or unfair outcomes
Efficient market outcome: - all opportunities for trading are exploited
- goods end up in the hands of those who value them the most
- it is not possible to make one better off without making another worse off
Pareto optimal-outcome: not possible to make one better off without making another worse off
1st welfare theorem: free exchange makes everyone best off → Edgeworth box
Pareto improvement: at least one is better off without any other being made worse off
Pareto efficient allocation: when the MRS’S are equal. Their value of bread i.c.t. water is the same
Contract curve: all efficient allocations
Utility possibilities curve:
2
, Production decisions: production can vary
combination of all points that have
production efficiency
Exchange efficiency: all trades that lead to higher utility are exploited
MRSa = MRSb
Production efficiency: all changes in allocation of production that lead to more production are
exploited
MRTSlabor = MRTSland
product mix efficiency: all changes in the mix of products that lead to higher utility are exploited
MRT = Pa/Pb
Competitive economies satisfy these 3 efficiencies
Fundamental theorems of welfare economics:
- every competitive economy is Pareto efficient
- every Pareto efficient resource allocation can be attained through a competitive market
Knowledge of opportunities is important for drive towards efficiency. If the knowledge is dispersed
among many people, prices can act to coordinate the separate actions of different people.
