Gold has a far-reaching history of ‘safe haven’ or ‘anchor of stability’. However, the epitome of precious metals has recently deviated from its historical price trend. Fluctuations and volatility have increased too. We argue that gold is not subject to bubbles (due to its scarcity in nature), although its price is. By means of a logical-analytical macroeconomic approach combined with...
