Populists Are Sometimes Right

Developing countries are often advised (or instructed) to undertake reforms recommended by "experts" who are called "technocrats" and are often backed by the IMF. Opposition to the reforms they propose is usually dismissed as "populist." Countries that fail to undertake these reforms are dismissed as craven or lacking political will, and soon suffer the consequences: higher interest rates when borrowing abroad.

But look closely at some of these "technocratic" proposals: many are more often based on ideology than economic science. Technocrats can of course reliably make an electricity plant work better. The goal is simple: to produce electricity at as low a price as possible. This is mostly a matter of engineering, not politics. Economic policies are usually not technocratic in this sense. They involve tradeoffs: some may lead to higher inflation but lower unemployment; some help investors, others workers.

Economists call policies where no one can be made better off without making someone else worse off Pareto efficient. If a single policy is better than all others for everyone , i.e., has no Pareto-efficient alternatives, it is said to be Pareto dominant . If choices among policies were purely Paretian, i.e., if no one was made worse off by choosing one policy, as against another, the choices involved would indeed be purely "technical."

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations.

  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.
