Discuss (d) the four branches

Public finance — the state's money-science: the revenue's raising (the taxes and the borrowing), the expenditure's spending (the services and the investments), and the deficits- and-debt's management — the government's household at the nation's scale. The discipline's four branches (the lawyer's map): The revenue law — the taxes (the income tax, the VAT, the customs, the excise — Unit 3 and Unit 6's world); The expenditure law — the budget-and-appropriation (Unit 5's world); The debt law — the loans and the guarantees (Unit 4's world); The fiscal-administration law — the departments, the accounts, the audit (Units 5-6).
