L’Immigration et l’État-providence

MUNICH – Le conflit armé qui déstabilise certains pays arabes a soulevé une énorme vague de réfugiés cherchant, pour beaucoup, à rejoindre l’Europe. En 2015, l’Allemagne a reçu à elle seule 1,1 million d’entre eux. Concomitamment, l’application du principe de libre circulation génère d’importants flux migratoires intra-européens, pourtant largement ignorés. En 2014, le solde migratoire net de l’Allemagne avec l’Union européenne était, fait sans précédent, de 304 000 personnes, et les chiffres de 2015 sont probablement comparables.

Certains États membres, dont l’Autriche, la Hongrie, la Slovénie, l’Espagne et la France, ainsi que le Danemark et la Suède, qui, tous deux, s’étaient d’abord montrés accueillants, ont réagi en suspendant, de fait, les accords de Schengen et en rétablissant les contrôles aux frontières. Les économistes n’en sont pas réellement surpris. Dans les années quatre-vingt-dix, des dizaines d’articles scientifiques ont paru sur la question des migrations dans les États-providence, qui envisageaient nombre des problèmes aujourd’hui d’actualité. J’ai moi-même beaucoup écrit à l’époque sur le sujet, tentant – en vain, le plus souvent – d’alerter l’attention des responsables politiques.

L’enjeu est essentiel. Les États-providence se définissent par le principe de redistribution : ceux dont les revenus sont au-dessus de la moyenne paient plus d’impôts et cotisent plus qu’ils ne reçoivent en retour des services publics, tandis que ceux dont la rémunération est inférieure à la moyenne paient moins qu’ils ne reçoivent. Cette redistribution, qui draine les ressources publiques nettes vers les ménages à faibles revenus, apporte une correction sensible à l’économie de marché, sorte d’assurance contre les vicissitudes de la vie et la dure loi du prix de la rareté, qui caractérise le marché et n’a que peu à voir avec la justice sociale.

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
