Services account for almost 70% of GNP and jobs in the EU, but the full economic potential of the service sectors is currently hampered by many Internal Market barriers. Examples of barriers to service provision are abundant. Service providers wishing to establish themselves in other Member States may face restrictive authorisation schemes and other disproportionate, possibly even discriminatory, requirements. Similarly, cross-border provision of services is sometimes hindered by obligations and administrative burdens imposed by national and local regulations. We excel in quantifying the economic importance of barriers to the Internal Market, and we advise on the pros and cons of specific regulation in relation to client objectives.
