In the fourteenth century, the Black Death killed as much as two thirds
of Europe's population; in the fifteenth, the introduction of
moveable-type printing rapidly expanded Europe's supply of human
capital; between 1850 and 1914, Russia's population almost tripled; and
in World War I, the British blockade starved some 800,000 Germans. Each
of these, Shocking Contrasts argues, amounted to an unanticipated shock,
positive or negative, to the supply of a crucial factor of production;
and elicited one of four main responses: factor substitution; factor
movement to a different sector or region; technological innovation; or
political action, sometimes extending to coercion at home or conquest
abroad. This book examines parsimonious models of factor returns,
relative costs, and technological innovation. It offers a framework for
understanding the role of supply shocks in major political conflicts and
argues that its implications extend far beyond these specific cases to
any period of human history.
