We model the agency relationship between managers and investors. Throu
gh socialization, ethical managers develop internalized norms which pr
event them from acting opportunistically. Unethical managers lack thes
e norms. Higher ethical standards on the part of managers increase eco
nomic activity in the short run. However, increased economic activity
increases opportunities to profit from unethical behavior, eroding eth
ical standards over the long run. When this rate of erosion i.5 high,
cycling of ethics and economic activity emerges. Otherwise, ethics and
economic activity converge to a stable long-run limiting value.
