En busca de estrategias de crecimiento

MILÁN – En 2008, la Comisión sobre Crecimiento y Desarrollo del Banco Mundial, que tuve el privilegio de presidir, presentó un informe con conocimiento actualizado sobre los modelos de crecimiento sostenible. Entonces, como ahora, una cosa estaba clara: las políticas que sostienen períodos de varias décadas de alto crecimiento, transformación estructural, aumento del empleo y los ingresos, y gran reducción de la pobreza se refuerzan mutuamente. El impacto de cada una resulta amplificado por las otras. Son ingredientes en recetas que funcionan, y lo mismo que en las recetas, la falta de un ingrediente puede afectar seriamente el resultado.

Para comprender las pautas de crecimiento (débil, frágil y con visos de empeorar) que vemos hoy en muchos países y en toda la economía mundial, deberíamos comparar la realidad con lo que esperaríamos ver en unas estrategias de crecimiento razonablemente integrales. Claro que hay muchas políticas capaces de sostener un crecimiento elevado, y hasta cierto punto dependen de cada país. Pero hay unos pocos ingredientes clave que aparecen en todos los ejemplos de éxito conocidos.

El primero es un alto nivel de inversión pública y privada. Los países en desarrollo exitosos invierten el 30% de su PIB o más. El componente del sector público (infraestructura, capital humano y la base de conocimiento y tecnología de la economía) se sitúa en la franja del 5 al 7%. Y las inversiones de los sectores público y privado son complementarias: las primeras aumentan la rentabilidad de las segundas, y con ella, su volumen.

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations. But, as European Council President Donald Tusk has said, the most difficult challenge – forging a workable deal that secures broad political support on both sides – still lies ahead.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
