According to Schumpeter’s theory, the main causes of economic development are determined by innovations implemented by producers-innovators and realized through credits created by banks from savings. Consumers play a passive role in this process and they can be characterized by routine behaviors. Changes in their activities are solely dependent on respective changes in a production system.

In contrast to this, the paper reflects the research path which interprets economic evolution as a process on the one hand pushed by technological changes, and on the other hand pulled by demand. This idea also extends the research program on modeling Schumpeterian evolution in the axiomatic Arrow-Debreu set-up.

In this context, the aim of the paper is a modification of the standard Arrow-Debreu model in such a way that consumers are seen as equipped with specific production-preference relations which enable them to interfere in producers’ activity, and consequently, influence innovative changes in a production sector of an economy by means of proinnovative preferences.
