Micro Flashcards
Allocative efficiency
Consumer satisfaction is maximised
Productive efficiency
Firm operates at lowest average cost, choosing appropriate inputs and producing Max output from those inputs
Ad valorem tax
Tax levied on a commodity, set as a percentage of the selling price
Adverse selection
Situation when a person at risk is more likely to take out insurance
Asymmetric information
Participants in a market have better information about market conditions than others
Average total cost (ATC)
Total cost divided by output
Buffer stock

Scheme intended to stabilise the price of a commodity.
Capitalism
Private ownership of resources , individuals are free to pursue their objectives with minimal gov interference
Planned economy

Competitive demand
Demand for goods in competition with another
Competitive market

Consumer surplus
Value consumers gain from consuming G/S above price paid
Consumption externality
Externality that affects consumption side of market (affect upon 3rd party) can be +-
Cost efficiency
Appropriate mix of FOP given relative prices of those factors
XED

—————————————
% change in P of Good B
Demand
Quantity of a G/S consumers are willing and able to buy at any possible price and time period
Demerit good
Good brings less benefit to consumers than expected , over consumed
Derived demand
Demand for a FOP which derives not from the factor itself but from the goods it’s produces

Production process is broken down into a sequence of stages , workers are assigned to particular stages
Economic efficiency
Productive + allocative efficiency reached
Economic growth
Expansion in the productive potential of an economy ( Increased GDP)
Economies of scale
Increase in the scale of production leads to production at a lower average cost
Elasticity
Sensitivity of one variable to changes in another variable
