The document discusses different types of government budget expenditures and deficits. It defines revenue expenditure as spending that does not create assets or reduce liabilities, such as pensions and salaries, while capital expenditure does create assets or reduce liabilities, like purchasing shares. It also defines plan expenditure as spending allocated to central plans and non-plan expenditure as unplanned spending like disaster relief. The document then explains the differences between revenue and capital deficits, fiscal deficits which include all expenditures and receipts except borrowings, and primary deficits which calculate deficits excluding interest payments on previous debts. It outlines the implications of each type of deficit and measures governments can take to reduce them.
