Business and Economics Unit 4 ­ Wider economic
How markets work?
Productive efficiency ­ Firms producing lowest possible unit cost with the resources
Allocative efficiency ­ Economies resources are allocated to their most efficient usage i.e.
output is optimised to meet the needs of the market.
Production possibility boundary
o To increase boundary - Increase people, technology.
o If more emphasis was placed on manufacturing, the opportunity cost would be a
reduction in output of services.
Allocative efficiency
o Point before the curve means economy is not working at maximum productive
o Resources which are not being used can be allocated to a specific sector without
reducing the output of another sector.
o Increase the overall output and achieve closer figure to 100% allocative efficiency
Both sectors grown
Balanced out economy
Pushed line closer
Must be demand, demand is decreasing causing line being pushed away
from PPB
When not up to PPB curve, not all resources being used, i.e. unemployed
Factors that Shift the PPB to the right
o Improvements to technology
R&D, investment in capital goods, innovation production processes
o New resources discovered
Mineral deposits found
Birth rate increases
Therefore increased labour resource
o Improving quality of existing resources
Skills, training, education
Improvements in quality of level
o Better management of resources
Division of labour and specialisation
Lean management/ JIT
o Encouraging enterprise
Government incentives the entrepreneurs to create wealth
It is possible to increase the output of one particular sector of the economy without
compromising output in other sectors
o Increase the potential productive capacity of output of services due to adaption of a
new technology breakthrough.
