In 1815, England emerged victorious after what had been nearly a quarter century of war with France. And during those years, encouraged by high prices and profits, England greatly expanded its agricultural and industrial capacity in terms of land and new machinery, with these activities often financed on credit. Improved harvests from 1812 to 1815 coincided with an export market boom in 1814, as the continent began to reopen for trade and speculation in South America increased. But the speculation turned to frenzy compared to the boom of 1810 as everything that could be shipped was shipped—until the speculation broke. The crisis started first with farmers and landlords, spread to business and industry, and was followed by mass starvation on the continent. In this edition of Crisis Chronicles, we recount the Crisis of 1816, the Year without a Summer, and the idea of Sunspot Equilibria.
