This is why I particularly want to thank Emilio Ontiveros for his dedication, not only in today’s book, to popularising these subjects among those not necessarily expert in the matter. b. Re-designing national policies Yet to attain their maximum effectiveness, improvements in global governance should be matched by national economic policies conducive to ensuring the benefits of globalisation reach all citizens. Indeed, while globalisation has general equilibrium aggregate effects that are admittedly positive, it may also have an adverse impact – as Professor Ontiveros states in his latest work – on specific sectors and groups. It is important to attempt to minimise these effects. Improvements in education and active employment policies providing for the readier redeployment of the unemployed are an essential element in this challenge. The impact of population ageing should also be prioritised by the authorities. Specifically, social insurance systems will have to progressively adapt so as to make sufficiency and intergenerational equity compatible, and for the sake of their own financial sustainability. Broadly, in the setting described, the greatest challenge facing public policies is the proper selection of instruments that may effectively attain the goals set and minimise the potential adverse effects. In this respect, public policies designed on the basis of the evidence available on their effects coupled with arrangements to regularly assess these policies will be crucial. Further, many national policies should be designed with international coordination mechanisms, if they are truly to be effective.

As I recently remarked1, the pillars acting as a basis for  1  See the opening address “Global imbalances and capital flows in the era of new technologies”, at the conference bearing the same name organised by the Banco de España and the Reinventing Bretton Woods Committee.

The aim thereby was to ensure they fulfilled their mission and to resolve potential conflicts on the basis of the principles of justice and equity for all the participating States. Such arrangements have, for decades, enabled the containment of certain unilateral actions. From my standpoint, and taking stock, the liberalisation of trade and financial exchanges in recent decades under these institutions has made, and continues to make, a net positive contribution to global growth. This has, moreover, helped improve substantially the opportunities for development, especially in the poorest countries, drastically reducing inequality and extreme poverty globally, at least at a pace never previously seen. Accordingly, these principles and institutions are, for me, as necessary today as they were then. However, the world has seen far-reaching change in the past 75 years. Currently, the setting of rapid transformation means some adjustments are needed to update international economic governance. Specifically, one of the key challenges at present is to improve the adaptation of the multilateral rules-based system in force since the Bretton Woods Agreements to the current circumstances and to future challenges.
