Competition and innovation in product quality: Theory and evidence from Eastern Europe and Central Asia
(Walter de Gruyter GmbH, 2014) Fatma Nur Karaman Kabadurmuş; Sajal Lahiri; Lahiri, Sajal; Karaman, Fatma Nur
This paper examines how the degree of competition affects incentives to innovate in product quality in a symmetric Cournot oligopolistic model. We model product quality in a quality-ladder framework and find an inverted-U shaped relationship between the number of firms in an industry and R&D efforts in innovation. We test this theoretical prediction using firm-level data for Eastern European and Central Asian countries from the Business Environment and Enterprise Performance Survey and find strong support for it. © 2021 Elsevier B.V.

Competition and product innovation by Turkish firms
(IGI Global, 2016) Fatma Nur Karaman Kabadurmuş; Sajal Lahiri; Lahiri, Sajal; Karaman Kabadurmus, Fatma Nur
This chapter examines empirically the determinants of research and development (R&D) activities by Turkish firms. It focuses on the question of how competition affects product innovation and not process innovation in Turkey. In particular we test if there is a non-linear relationship between R&D activities of a firm and the degree of competition in that industry. We use Turkish firm-level data from the Business Environment and Enterprise Performance Survey (BEEPS) and find strong support for an inverted-U relationship between the two variables. © 2016 Elsevier B.V.
