La seudo-revolución verde

COPENHAGUE – Frente al avance de una recesión mundial, hoy peligra cualquier acción contundente contra el calentamiento global. Esto importa, porque en poco más de un año, el mundo se sentará en Copenhague para negociar el tratado que seguirá al fallido Protocolo de Kyoto. Sin embargo, en vista de que la gente está perdiendo empleos e ingresos, la ayuda económica inmediata parece importar más que las diferencias de temperatura de aquí a 100 años.

Sin embargo, muchos expertos verdes empezaron a decir que la crisis financiera no hace más que aumentar la necesidad de emprender una acción contra el cambio climático. Instan al presidente electo de Estados Unidos, Barack Obama, a propiciar una “revolución verde” con grandes inversiones en energía renovable, con el argumento de que esto podría crear millones de nuevos empleos “verdes” y abrir nuevos mercados de volumen considerable. No sorprende que estos sentimientos sean expresados a viva voz por líderes empresarios que viven a costa de este tipo de subsidios. Ahora bien, ¿estas peticiones son inversiones inteligentes para la sociedad?

El problema con el argumento de la revolución verde es que no se ocupa de la eficiencia. La mayoría de las veces se la elogia porque ofrece nuevos empleos. Pero miles de millones de dólares en subsidios impositivos crearían una gran cantidad de empleos nuevos en casi todos los sectores: el punto es que muchos sectores que requieren menos inversiones en bienes de capital crearían muchos más empleos por una determinada inversión del dinero de los contribuyentes.

    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.
