小弟今年dse試下答
(b)(i) As the number of tourists drops, export of services decreases. Aggregate demand and output drop. As many employees were laid off, the number of labour drops. Short-run aggregate supply and output drop.
(ii) Unemployment rate = (Unemploted population / labour force)
As the industry which depends on visitors is suffering losses, tour guides may be fired and lose their jobs. Unemployed population increases while labour force remains unchanged. Unemployment rate increases.
(iii) Economic variable: Fiscal balance
As the global economy suffers major pain from coronavirus, the companies worldwide have less profits and profit tax revenue decreases. The labours have less salaries due to the worsening economy, so profit tax revenue drops. At the same time, the government has to provide more unemployment benefits because of the increasing unemployment rate, so the govenment expenditure increases. The fiscal balance worsens as a result.
