Flexibility is a desirable feature of an economic system. Structural rigidities can result in sluggish growth and inflationary pressures; many economic models, however, display considerable system flexibility because of the use of unacceptably unrealistic assumptions. The primary "real-life" features endowing the system with flexibility are unemployment and excess capacity. While realistic, unemployment is economically costly and socially undesirable. In economic theory, there appears to be a trade-off between flexibility and realism. In reality, there appears to be a trade-off between flexibility and full employment. What has not been adequately recognized, however, is the degree to which policies are available that can promote higher levels of employment—and even full employment—without resulting in deleterious rigidity.
