Economic and monetary union

    • Fiscal policies, including government debt and deficit

    • Acceptance of the monetary policy run by the European Central Bank (ECB)

  • The European Union argues that this coordination is beneficial to all member states 

    • Benefits of greater size brings efficiency and economic stability

    • Benefits of higher growth and more employment 

Economic governance under EMU

  • Within the EMU there is no single institution responsible for economic policy

  • Instead, the responsibility is divided between Member States and the EU institutions

  • The main actors in EMU are:

    • The European Council, which sets the main policy goals

    • The Council of the EU, which coordinates EU economic policy-making

    • The 'Eurogroup', which coordinates policies of common interest to member states

    • The member states, which set their national budgets within agreed limits for deficit and debt, and formulate their own policies which adhere to EU guidance involving employment and capital markets

    • The European Commission, which monitors performance and compliance

    • The European Central Bank (ECB), which sets monetary policy and acts as central supervisor of financial Institutions 

    • The European Parliament, which shares the job of formulating legislation with the Council and reinforces democratic application of policies 

Supranational versus intergovernmental approaches

  • A supranational organisation is an organisation made up of multiple countries where member states agree to share or transfer some sovereignty, allowing the organisation to make binding decisions that can override national laws in certain areas

  • The EU is, by definition, a supranational organisation and is regarded as such by the international community

    • It has power to exercise some of the functions of a state in global politics 

    • Unlike other intergovernmental organisations, the sovereignty of member states is significantly reduced

    • Member states of the EU accept that the reduction of sovereignty because they expect economic benefits and security will be the result
