abstract = "This research empirically analyzes seller's product portfolio strategy in the mobile application (apps) market. We use crosssectional data on the most downloaded application rankings in the Apple App Store to examine the impact of app portfolio strategy on sales performance. We find that app portfolio diversification is positively correlated with sales performance. We also find that sellers who offer a combination of free and paid apps have higher sales performance than those who deliver paid apps only. Furthermore, the results show that sellers with scale advantages compete differently from sellers in the long tail. These findings have implications for theorizing about product portfolio management in the emerging mobile app store markets.",
