A Era dos Megaprojectos

WASHINGTON, DC – Parece que estamos a entrar numa nova era de megaprojectos em que os países, em especial os do G20, incentivam o sector privado a investir fortemente em infra-estruturas que custam vários milhões de dólares (se não milhares de milhões, ou mesmo biliões), como gasodutos, barragens, sistemas hídricos, redes eléctricas e redes rodoviárias.

A despesa em megaprojectos eleva-se já a cerca de 6 a 9 biliões de dólares por ano, ou seja, cerca de 8% do PIB mundial, o que a torna “o maior boom de investimentos da história da humanidade”. Além disso, a geopolítica, a procura do crescimento económico, de novos mercados e de recursos naturais está a canalizar ainda mais financiamento para projectos de infra-estruturas de grande dimensão. No pico desta explosão potencialmente sem precedentes de tais projectos, os líderes e os credores mundiais parecem ser relativamente alheios às onerosas lições do passado.

De facto, os investimentos em infra-estruturas podem servir necessidades reais, contribuindo para dar resposta a um aumento esperado da procura de géneros alimentícios, água e energia. Contudo, a menos que a explosão de megaprojectos seja cuidadosamente redireccionada e gerida, é provável que o esforço se venha a revelar contraproducente e insustentável. Na ausência de controlos democráticos, os investidores podem privatizar os lucros e socializar as perdas, fixando-se em abordagens de utilização intensiva de carbono e outras que geram prejuízos ambientais e sociais.

    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.

    ROBERT J. BARRO vs. JASON FURMAN & LAWRENCE H. SUMMERS on the impact of the GOP tax  overhaul.


    • Congressional Republicans are finalizing a tax-reform package that will reshape the business environment by lowering the corporate-tax rate and overhauling deductions. 

    • But will the plan's far-reaching changes provide the boost to investment and growth that its backers promise?

  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.
