Product Compatibility and Technological Innovation


  • Jeong-Yoo Kim


This paper explores the relationship between the firms' compatibility choice and quality improving technological progress in a static model. I demonstrate that firms' compatibility choice in anticipation of quality improving innovation critically depends on how users' expectations regarding the network size are formed. In particular, if users have rational expectations the firm with the small innovation will prefer full compatibility whereas the firm with the large innovation will prefer complete incompatibility,, and as a result, with the small innovation, excessive standardization may occur.
