"A virtuous circle and a vicious circle (also referred to as virtuous cycle and vicious cycle) are economic terms. They refer to a complex chain of events that reinforces itself through a feedback loop. A virtuous circle has favorable results, while a vicious circle has detrimental results.
Both circles are complexes of events with no tendency towards equilibrium (at least in the short run). Both systems of events have feedback loops in which each iteration of the cycle reinforces the previous one (positive feedback). These cycles will continue in the direction of their momentum until an external factor intervenes and breaks the cycle. The prefix "hyper-" is sometimes used to describe these cycles if they are extreme. The best-known example of a vicious circle is hyperinflation. ...
Example in management.
Virtuous circle.
An employer's investment in his employees’ ability to provide superior service to customers can be seen as a virtuous circle. Effort spent in selecting and training employees and creating a corporate culture in which they are empowered can lead to increased employee satisfaction and employee competence. This can result in superior service delivery and customer satisfaction. This in turn will create customer loyalty, improved sales levels, and higher profit margins. Some of these profits can be reinvested in employee development, thereby initiating another iteration of a virtuous cycle." [en.wikipedia.org/ wiki/ Virtuous_ circle_ and_ vicious_ circle]
