Abstract: This paper focuses on how characteristics of regions pertaining to local information about product varieties and markets as well as networks for the transmission of information about innovation opportunities influence the arrival of innovation ideas to existing and potential entrepreneurs. We formulate a model where entrepreneurs or innovating firms introduce new products in a quasi-temporal setting. Market conditions are characterized by monopolistic competition between varieties belonging to the same product group, in which there is entry and exit of varieties. Firms innovate in response to the arrival of innovation ideas. To realize these ideas firms have to make an R&D investment and a firm’s decision to export a variety to a new market is associated with a market channel investment. The theoretical model is used as a reference when formulating two regression models, with which we estimate factors that can explain the introduction of new export varieties by firms in different regional milieus. In one model we examine the emergence of new export firms, and in the second model we investigate the appearance of new export varieties. Results are consistent with the assumption that knowledge and information flows have a positive influence on the frequency of arrival of innovation ideas to firms.
