Final answer:
Government-wide financial statements use the economic resources measurement focus and the accrual basis of accounting to provide a complete financial picture. Spending is measured as a percentage of GDP for more accurate comparisons over time and across different economies.
Step-by-step explanation:
The question asks about the measurement focus and basis of accounting for government-wide financial statements. When preparing these statements, governments typically use the economic resources measurement focus and the accrual basis of accounting. This approach includes all assets and liabilities associated with the operations of the government and reports on all revenues and expenses when they are earned or incurred, regardless of when cash is exchanged. This method presents a broader and more complete picture of the government's finances than would be shown using only current financial resources and the cash basis of accounting. By reporting government spending as a percentage of GDP instead of in nominal dollars, it allows for a better comparison over time and across different economies, adjusting for inflation and economic growth.
