Week 4 Flashcards
Whats the great economic problem?
To arrange our limited resources to satisfy as many of our wants as possible.
Define speculation
The attempt to profit from future price changes is called speculation.
Define Futures
Futures are standardised contracts to buy or sell specific quantities of a commodity or financial instrument at a specified price with delivery set at a specific time in the future.
Describe a forecasting market
A forecasting market is a highly speculative market designed to allow prices to be interpreted as opportunities and used to make predictions?
How do we allocate our limited labor and capital across the industries to satisfy as many of our wants as possible?
To use our limited resources most effectively, we would like resources to flow from low-profit industries to high-profit industries.
In what cases does the ‘invisible hand’ not work
If prices dont accurately signal costs and benefits
Explain the elimination principle:
The elimination principle states that in a competitive market, profits above the normal range and below the normal range are temporary. The Profits above the normal profits are eliminated by a new entry in the market, and profits below the range can be eliminated by the exit of firms.
Explain the Ricardian rent
The result of the possession of a natural or man-made idiosyncratic, scare factor
Is tying and bundling bad?
Bundling and tying are easier to do than price discrimination as there is less information required and fewer arbitrage issues.
Extra money is spent to keep competitors out of the tied market
Potentially anti-competitive on the final product - discouraging innovation, increasing prices
Explain how markets link to one another
- Shifts in the supply and demand in one market ripple across markets worldwide. Products are interrelated.
- Entrepreneurs are constantly looking for ways to lower costs - moving resources around leads to shifts
- This links markets that seem like they are a world away
- Are these changes to stable enough or is gov intervention required?
How can we solve the great economic problem?
- Central planning
- Price system
Explain central planning:
- Central planning is unworkable
- Problems of information and incentives
- Will not solve that the price system aggregates all this information
Explain the price system
- Each user of a product will compare the value in their use with the value in alternative uses
- Each user has an incentive to give up their product if it has lower value in their use
Explain how prices are incentives, signals and predictions
- When prices rise, buyers are encourages to use less or substitute away
- It is also a signal to suppliers to provide more
- Price signals and the accompanying profits and losses tell entrepreneurs what areas of the economy consumers want expanded and what areas they want contracted
Explain the first property of the invisible hand
Cost minimisation
All firms face the same market price for a given commodity
- To maximise profits, each firm adjusts its output until P = MC
- Thus, in a comp market with N firms, they all produce where P= MC1 = MC2 = MCN
Explain the second property of the invisible hand
Balance of Industries
Define Consumer surplus
Consumer surplus is the difference between willingness to pay for a good and the price that consumers actually pay for it.
