Labour mobility is an important prerequisite for the efficiency of labour markets. In the EU, however, different standards across countries present an implicit economic barrier for high-skilled professionals. This column examines how the recent EU harmonisation of professional standards in accounting affected cross-border migration relative to other professionals. The harmonisation had a strong positive effect on accountants’ cross-border migration. Harmonisation could thus be a potentially powerful tool for policymakers seeking to improve labour market efficiency.

The global value chain revolution has changed trade and trade agreements. Trade now matters for making goods as well as selling them. Trade governance has shifted away from the WTO towards megaregional agreements. This column argues that 21st-century regionalism is not fundamentally about discrimination, and that its benefits and costs are best thought of as network externalities and harmonisation costs respectively. More research is needed to determine how the megaregional trade agreements across the Pacific and Atlantic will fit with the WTO.

The recent launch of negotiations on a transatlantic trade and investment deal has been widely welcomed by policymakers. This column warns that the aspect of the deal that provokes the greatest excitement – its focus on regulatory barriers like mandatory product standards– should evoke the greatest concern. Regional harmonisation may increase intra-regional trade yet exports from excluded developing countries could be hurt.

The EU is planning to harmonise data protection. This column balances the benefits of harmonisation against the estimated costs to business – especially small and medium-sized enterprises – and the macroeconomic costs more generally. The net compliance costs will perhaps be larger than the EU predicts.
