An economy experiences several events over a year. Which of the following events represents an expenditure that is not included when calculating the total planned expenditure, also known as aggregate demand?

A country's price index is calculated using a basket of goods. The table below shows the main categories in the basket, the percentage of a typical household's budget spent on each (its weight), and the price change for each category over the past year.

Based on this data, which category's price change contributed the most to the overall increase in the price index?

Inflation Dynamics under a Currency Peg

Suppose that retired individuals spend a much larger proportion of their income on healthcare than the average household. If the price of healthcare services increases by 10% while all other prices remain constant, how would the change in the cost of living for retirees compare to the change in the official, nationally-calculated price index?
