Özet (Çeviri)
This research investigates the roles of competition, trade policies, credit constraints, and R&D subsidies as factors a ecting innovation and o ers theoretical and empirical analysis to study the interrelationships between these variables. In the theoretical parts, we develop a number of predictions. To test these predictions, this study uses Turkish rm-level data from Business Environment and Enterprise Performance Surveys (BEEPS 2002, 2005, 2008 and a panel data for 2005-2008), conducted by the European Bank for Reconstruction and Development (EBRD) & World Bank. This dissertation develops three di erent oligopoly models in three chapters which are explained below. All three models adapt the well-known Grossman and Helpman (1991) quality ladder model of R&D process, which is indeterministic in nature. Chapter 1 considers the e ect of the intensity of competition on the incentives to innovate for identical rms competing in a Cournot oligopolistic market. In this framework, we examine the impact of an increase in competition on R&D activities among others. We nd an inverted-U shaped relationship between competition and R&D e ort.Chapter 2 analyzes rms' investment on R&D in an imperfectly competitive setting. The focus is on cost asymmetries in a duopoly model. The baseline model setting assumes rms invest in a quality ladder type of R&D process with probabilistic returns and have to borrow both at the innovation stage and the production stage. We nd that if the rm is more e cient than the rival, e ort on R&D will decrease less upon facing a common interest rate. Chapter 3 extends the \reciprocal dumping" model of Brander and Krugman (1983) by introducing a quality ladder type of product innovation. In this new framework, we show that tari s increase the e ort to innovate for home rms, while it decreases the e ort on R&D for foreign rms. Furthermore, we analyze the e ects of domestic tari s on domestic welfare. Domestic welfare increases only if the bene ts from increasing R&D e ort of the domestic rm can su ciently cover for the decreasing R&D e ort on Foreign's exports.
