Una nuova strategia macroeconomica

NEW YORK – Pur essendo macroeconomista sono in disaccordo con le due principali scuole di pensiero economico degli Stati Uniti: la neo keynesiana focalizzata sull’incoraggiamento della domanda aggregata, e gli economisti che sostengono l’offerta che sono invece focalizzati sulla riduzione delle tasse. Negli ultimi anni, entrambe le scuole hanno cercato di migliorare la debole performance delle economie a reddito elevato senza riuscirvi. E’ quindi giunta l’ora di pensare ad una nuova strategia basata su una crescita sostenibile e focalizzata sugli investimenti.

La sfida centrale della macroeconomia è quella di stanziare le risorse della società ai fini del loro miglior utilizzo. I lavoratori che decidono di lavorare dovrebbero poter trovare un lavoro, le fabbriche dovrebbero utilizzare il loro capitale in modo efficiente, mentre il risparmio del reddito dovrebbe essere investito per garantire il miglioramento del benessere futuro.

E’ proprio su questa terza sfida che sia i neo keynesiani che i sostentiori dell’offerta hanno gettato la spugna. La maggior parte dei paesi a reddito elevato, tra cui gli USA, gran parte dell’Europa ed il Giappone, non investono infatti in modo adeguato o in modo strategico ai fini di un miglior utilizzo futuro. Esistono due modi per investire: a livello nazionale e a livello internazionale. Tutti i paesi a livello mondiale sono ormai carenti in entrambe le tipologie di investimento.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
