Answer:
They struggle with a. fiscal squeeze.
Step-by-step explanation:
Fiscal squeeze is experienced when income reduces over time and expenses continue to increase, which cause the body in question to experience problems in meeting its budgetary requirements.
In the case of central cities, a shrinking tax base is a reduction in income as public entities derive their incomes from taxes. Likewise, an increase in the demand of urban services increase their budgetary requirements as it is incumbent upon them to provide these services. When both of these stimuli are introduced, they experience a fiscal squeeze.
