Why Are Savings Patterns So Different?

While global imbalances have preoccupied many observers, few have sought to explain the divergence in world savings behavior. One reason may be that credit markets are more developed in advanced economies than they are in emerging countries, particularly in terms of the degree to which households are able to borrow.

BEIJING – Ever since the integration of emerging markets into the global economy began in the early 1990’s, three striking trends have emerged: a divergence in private savings rates between the industrialized core and the emerging periphery (the former experiencing a sharp rise, and the latter a steady decline); large global imbalances between the two regions; and a drop in interest rates worldwide. But, while global imbalances have preoccupied many observers, few have sought to explain the divergence in world savings behavior.

In 1988, the household savings rate in China and the United States was roughly equal, at about 5%. Yet, by 2007, China’s household savings rate had risen to a staggering 30%, compared to just 2.5% in the US. The pattern is not uncharacteristic of other industrialized countries relative to emerging markets over the last two decades (Figure 1).

Savings behavior invariably reacts to changes in interest rates, which have fallen steadily over the last two decades to today’s record-low levels. But how can savings patterns be so different – often opposite – in globalized economies that are well integrated into world capital markets?

    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

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.
