Q

Demand-defficient unemployment

A

Unemployment caused by there not being enough demand in an economy

This can be shown on an ADAS diagram by an inward shift in aggregate demand - Negative output gap

If there is not enough demand for goods and services, then firms produce less, meaning they require less labour

Even if you acquire the necessary skills to have a tertiary sector job, you may not be able to relocate to where these new jobs are, as the area may be too expensive, or you may have to look after family.

A

Refers to the act of guarding a country’s industries from foreign competition and restrict international trade

Example given depends on PED

104
Q

Structural cause of a current account deficit

A

Current account deficit caused by supply factors, (Ex: High unit labour costs - Higher prices passed onto consumers - This will cause export revenue to decrease as they will be less competitive - Assuming goods are price elastic)

106

PED is elastic

112
Q

Income Elasticity of Demand - YED

A

Elastic inferior good

114
Q

YED between -1 and 0
