1. Introduction: public intervention in the economy
Public intervention is widespread and largely influence our daily life: The government provides goods and services (health, social assistance, education, defence, environment, infrastructures, etc.), it defines the rules for socio economic behaviour (legal structure and property rights, environmental regulation and protection of natural resources, safety regulations, employment regulations, etc.) it ensures a stable socio-economic environment (macroeconomic policies,..) it finances its activities with taxation and this affects income distribution, and production, consumption and saving decisions. 13
14
The extent of public intervention
Public intervention in the economy is very differentiated across countries: In extent as shown for example by its incidence on GDP In the composition of spending In the structure and incidence of taxation The variance among countries is mainly explained by different choices concerning the distributive role of government.

Public Deficit and Public Debt
In most countries public expenditures are higher than revenues The public balance is the difference between government spending and tax revenues in a particular year. The public balance may be positive or negative (deficit) The public debt is the total amount of money owed by the government to creditors due to the accumulation of past deficits. The crisis has increased the public deficit and debt in all OECD countries. Austerity policies (cuts in public expenditures and increased in taxes) have been implemented to reduce public deficits and public debt, but these policies have made it more difficult to get out of the recession.

Fundamentals of Public Economics
Public economics: considers the role of the government in market economies, the rationale behind its intervention and the economic and social effects in terms of the efficiency and equity trade offs. MAIN QUESTIONS: When and how much should the government intervene in the economy (should the government intervene more or less than it does?) How might the government intervene (should it intervene differently?) What are the effects of public intervention? How social choices are made? 24
25
When should the government intervene in the economy?
Roles and tools of Government intervention Behind public intervention in modern market economies is the need to correct actual or perceived market failures (efficiency goal) and to ensure an equitable distribution of resources (equity goal). Often there is a trade off between these two goals. The public sector has different roles in market economies: Allocation of resources (efficiency goal) Income (re)distribution (equity goal) Stabilisation of the economic cycle These roles interact with each other. 25
26
When and how to intervene? Allocation role (growth and efficiency)
ALLOCATION ROLE: provide in an efficient way (increasing the size of the pie) goods and services when the market is not able to produce them efficiently (market failures) through: The production of public goods or the public financing of private provision: i.e. all those goods and services which are under (or not) produced by the market, due to market failures; The regulation of market activities to support market competition (property rights, legal system, restrictions ) The use of Taxes and subsidies which change the market price of goods or services and affect the production and consumption decisions of economic agents. 26
27
When and how to intervene? Redistributive role (poverty reduction)
The aim is to foster equity correcting the distribution of resources (how the pie is distributed) resulting from market mechanisms, by shifting resources from some groups in society to others and/or by changing initial endowments through: Monetary transfers (such as welfare benefits to support the income of the poor or the unemployed) Transfers in kind (provisions of public services such as education, health services, social services) Taxes/subsidies (for example with progressive taxation or exemptions or subsidies) 27
28
When and how to intervene? Cycle Stabilisation role
Smoothing the business cycle and external shocks, supporting full employment and controlling inflation through: Fiscal policy (transfers and taxation, automatic stabilizers, public expenditures) Support to productive activities 28
29
What are the effects of government intervention?: Government failures
Behind public intervention in modern market economies is the need to correct actual or perceived market failures (efficiency goal) and to ensure an equitable distribution of resources (equity goal) However government intervention may also produce negative direct and/or indirect effects (government failures) due to: Limited information Limited control on private markets responses to public intervention Limited control over the public bureaucracy Limitations imposed by the political process
30
What are the effects of public intervention?
Have to consider the timing (short vs long term effects) and direct and indirect effects of public intervention on individuals and markets: Direct effects : effects expected assuming that the behaviour of economic agents do not change as a consequence of government intervention Indirect effects: effects arising because economic agents change their behaviour in response of the intervention (for example increasing taxation may reduce labour supply) It is very difficult to measure effects (especially indirect and long term effects) and to establish causation: i.e. whether the effects we observe are due to the government intervention under analysis or not: impact evaluation and cost-benefits analysis (see Gruber ch.3)
31
How decisions are taken?The analysis of social choices
Political economy studies how the political decision making process produces decisions that affect individuals and the economy. This part of public economics analyses how socially desirable goals are chosen Socially desirable goals relate to: - the capacity to support socio-economic growth, - the capacity to guarantee adequate living conditions to citizens, - the capacity to guarantee equality in opportunities for all.
32
Key economic issues in public economics
Efficiency: What is produced, how it is produced and how much it is produced (public vs private goods/services): given available resources make the pie as large as possible Equity For whom it should be produced and who should pay for it: distribute the pie in the most equitable way How are decisions taken? Trade offs: an efficient outcome could be not equitable an equitable outcome could be inefficient
