Gold standard

A gold standard is a monetary system in which the standard economic unit of account is based on a fixed quantity of gold. The gold standard was the basis for the international monetary system from the 1870s to the early 1920s, and from the late 1920s to 1932 as well as from 1944 until 1971 when the United States unilaterally terminated convertibility of the US dollar to gold, effectively ending the Bretton Woods system. Many states nonetheless hold substantial gold reserves. Historically, the silver standard and bimetallism have been more common than the gold standard. The shift to an international monetary system based on a gold standard reflected accident, network externalities, and path dependence. Great Britain accidentally adopted a de facto gold standard in 1717 when Sir Isaac Newton, then-master of the Royal Mint, set the exchange rate of silver to gold too low, thus causing silver coins to go out of circulation. As Great Britain became the world's leading financial and commercial power in the 19th century, other states increasingly adopted Britain's monetary system. The gold standard was largely abandoned during the Great Depression before being re-instated in a limited form as part of the post-World War II Bretton Woods system. The gold standard was abandoned due to its propensity for volatility, as well as the constraints it imposed on governments: by retaining a fixed exchange rate, governments were hamstrung in engaging in expansionary policies to, for example, reduce unemployment during economic recessions. According to a survey of 39 economists, the vast majority (93 percent) agreed that a return to the gold standard would not improve price-stability and employment outcomes, and two-thirds of economic historians reject the idea that the gold standard "was effective in stabilizing prices and moderating business-cycle fluctuations during the nineteenth century." Nonetheless, according to economist Michael D. Bordo, the gold standard has three benefits: "its record as a stable nominal anchor; its automaticity; and its role as a credible commitment mechanism.
