The Hypothesis of the Somatic Marker, by Antonio Damasio, perfectly explains the striking Argentine case Argentina's addiction to the US dollar, in times of uncertainty in national economic policy, is among the highest in the modern world. And while it is expected the search for stable currencies to invest in times of crisis (the famous flight to quality), the fever that is unleashed in Argentina is huge, causing the exchange rate to overreact remarkably. Thus, when the price of the US dollar rises in high proportions, instead of causing a fall in its quantity demanded, on the contrary, its quantity continues to rise in Argentina, defying traditional economic theory, and forcing governments to take excessive hard measures to stop these runs: control of changes, excessive increases in the interest rate in national currency, among other highly recessive measures. The answer is in the somatic marker of the Argentine brain: its addiction to the dollar is enormous.
