Idea in Brief

The Problem

In theory, companies create value for stakeholders by making risky investments. In practice, however, managers in large corporations routinely quash risky ideas in favor of marginal improvements, cost-cutting, and “safe” investments.

The Cause

Most managers in large organizations are significantly more risk-averse than CEOs, who consider each investment in the context of a greater portfolio.

A New Approach

This article explains how loss aversion works, presents an analysis of just how much value managers’ attitudes toward investment risk leave on the table, and offers suggestions for changes in practices and systems.

In theory, companies are supposed to create value for stakeholders by making risky investments. And as long as no single failure will sink the enterprise, those investments may be quite large. It won’t matter if even a significant percentage of them fail so long as the success of other bets compensates, which usually happens. It’s an approach to investment that’s supported by economic theory going back to the 1950s work of Nobel laureate Harry Markowitz on portfolio optimization.
