o Describe the roles of government bodies that determine national fiscal policies.

The roles of government bodies that determine national fiscal policies are crucial for managing a country's economy. These bodies typically consist of various government agencies, departments, and legislative bodies. Here are the key roles they play:

1. Executive Branch: The executive branch, comprising the head of state (president or prime minister) and their appointed officials, has the primary responsibility for formulating and implementing fiscal policies. They develop long-term economic plans, set budgetary priorities, and execute fiscal measures.

2. Ministry of Finance: The Ministry of Finance is the key government department responsible for fiscal policies. It formulates and proposes the budget, manages public spending, prepares the annual economic report, and advises the executive branch on economic matters.

3. Central Bank: Though not a direct part of the government, the central bank plays a vital role in determining fiscal policies. It is responsible for managing monetary policy, controlling the money supply, regulating interest rates, and maintaining stability in the financial system.

4. Fiscal and Economic Agencies: These are specialized agencies that provide expertise and analysis on fiscal matters. They gather data, conduct economic research, and advise the government on policy decisions. Examples include the Congressional Budget Office in the United States or the Office for Budget Responsibility in the United Kingdom.

5. Legislative Bodies: Parliament, Congress, or other legislative bodies play a vital role in determining fiscal policies. They debate and pass laws regarding taxation, government expenditure, and budget allocations. Legislators review and approve the proposed budget, exercising oversight over the government's fiscal decisions.

To understand the specific roles and functions of these bodies in a particular country, it is essential to refer to the constitution, laws, and governance structure of that nation.
