Since the US stock market crashed on October 19, 1987, many studies have been conducted to learn from this experience in the hopes of avoiding a similarly adverse future fall. The book, originally published as a special issue of the <em>Journal of Financial Services</em> <em>Research</em>, considers some of the important policy adjustments that have been implemented in the wake of the 1987 crash. Taken separately and together, these five papers offer a synthesis and summary of the most important policy innovations that have evolved since the largest single-day decline in stock market history.
