Coronavirus crash is a true "black swan"

The analysis didn’t account for a “Black Swan,” a term for an improbable and unforeseen event. Instead, it explored the idea of a “Great Moderation,” which is characterized by low volatility, sustainable growth and muted inflation.

“Overall, the changes underlying the Great Moderation appear intact, and we see the economy as structurally less recession-prone today,” Goldman economists Jan Hatzius and David Mericle wrote.

The economy, they argued, would settle gently after 11 years of growth.

“While new risks could emerge, none of the main sources of recent recessions — oil shocks, inflationary overheating, and financial Imbalances — seem too concerning for now. As a result, the prospects for a soft landing look better than widely thought.”
