Die Potenziale des Binnenmarkts werden noch nicht voll genutzt. Die folgenden Vorschläge gibt es dazu:

• We recommend a two-pillar strategy:
  • for sectors with large externalities and/or economies of scale (such as energy or telecoms), regulations should be harmonised and at least close coordination between regulators should be achieved;
  • for other services sectors, the efficiency of individual regulations on a cost-benefit basis with respect to their objective should be assessed, with systematic benchmarking.
• We also recommend pursuing a credible environmental policy agenda on a destination
  basis (impacting both EU and non-EU firms) rather than on an origin basis (which is the case
  today), through a combination of ambitious technical standards, a reference path for the carbon
  price and revenue-neutral tax instruments. This would stimulate long-term investment in
  the energy transition without overly hurting EU firms’ competitiveness.
• To further stimulate investment, especially in innovative sectors, we suggest moving
  ahead decisively with the capital markets union agenda. In parallel, the use of EU funds
  should be reviewed taking into account the objectives of economic convergence, spillovers
  between member states and solidarity.
• EU national governments are responsible for welfare-related redistribution. However
  EU policies can help by empowering member countries to address the possible effects of EU
  integration, or by developing EU-wide instruments to limit its impact on possible losers.
• We argue that tax and social security avoidance or fraud need to be combatted with modern tools,
  eg a single electronic interface to monitor the payment of social charges of posted workers in
  their home countries. In order to fight corporate tax avoidance and improve tax fairness, the
  interest and royalties directive could be modified if the project of a common, consolidated
  corporate tax base (CCCTB) proves too difficult to agree.
• Finally, we recommend making social security systems more neutral with respect to
  intra-EU migration, eg by introducing the full continuation of home-country unemployment
  rights for migrant jobseekers, with closer cooperation between national employment services,
  and by centralising information on pension entitlements on a single platform.
