Freelancing is based on the principles of the fully transparent marketplace.
Both the contractors as well as their buyers have a direct and comprehensive overview of the market situation.
Not only the quality and services of contractors, but also their rates are known to all participants. This way they can make the best possible market decisions (fully in the spirit of game theory of Professor Selten).
The contractors are choosing their market position in an optimal way while the buyer can choose the most appropriate supplier.
Other mechanisms at Freelancing are the mandatory hourly rates, the appropriate incentives for professional behaviour, feedback and quality rating mechanisms and the simple and fast transactions.
