My name is Joost (/Yoast/) Rietveld, I am Assistant Professor in Strategic Management at the Rotterdam School of Management (RSM) of the Erasmus University in Rotterdam (Netherlands). I study platform competition. More specifically, I study how dynamics at the platform level affect the adoption of complements such as apps, video games, or advertisements in newspapers. In my job market paper I studied the effect of changes to the platform user-base on the competition between video games in the context of the sixth generation console video games market. Other research interests include the impact of digitization on strategy and, more broadly, technological change. Some of my work is published in Research Policy and in the strategy textbook The Strategy Process (ed. Mintzberg et al.). Prior to coming to RSM, I was a visiting scholar with the department of Management & Organizations at New York University’s Stern School of Business for two and half years. At NYU developed and taught a full semester course on the business side of the video game industry. I obtained my PhD. from Cass Business School of the City University of London (United Kingdom).
