We study how external versus internal innovations promote economic growth through a tractable endogenous growth framework with multiple innovation sizes, multi-product firms, and entry/exit. Firms invest in external R&D to acquire new product lines and in internal R&D to improve their existing...

We document a series of new facts about the very first firms and patents that form new edges in the directed citation networks across patent categories. We call them pathfinder firms and patents. First, the typical pathfinder firms are very larger firms. Second, the average pathfinder patents...

We study how exploration versus exploitation innovations impact economic growth through a tractable endogenous growth framework that contains multiple innovation sizes, multi-product firms, and entry/exit. Firms invest in exploration R&D to acquire new product lines and exploitation R&D to...

We study how exploration versus exploitation innovations impact economic growth through a tractable endogenous growth framework that contains multiple innovation sizes, multiproduct firms, and entry/exit. Firms invest in exploration R&D to acquire new product lines and exploitation R&D to...

We study how exploration versus exploitation innovations impact economic growth through a tractable endogenous growth framework that contains multiple innovation sizes, multi-product firms, and entry/exit. Firms invest in exploration R&D to acquire new product lines and exploitation R&D to...

We build a tractable growth model where multi-product incumbents invest in internal innovations to improve their existing products, while new entrants and incumbents invest in external innovations to acquire new product lines. External and internal innovations generate heterogeneous innovation...

This study examines the relationship between innovation and economic growth. More precisely, it seeks to check whether African countries should choose to innovate locally by investing in research and development (R&D) instead of importing innovative technology. To achieve this goal, we used a...

This paper presents an econometric analysis of the impact of collaboration with universities on the innovative output of firms. We also illustrate the differences that emerge from robustness checks, based on different matching estimators and samples. Our findings strongly suggest that university...

This study quantifies the impact of process and product innovation on employment growth in Bolivia by using microdata from a survey on innovation conducted in Bolivia in 2016. Following the model of Harrison, Jaumandreu, Mairesse, and Peters (2008) and the adaptations for Latin America of Crespi...

We model distribution, the delivery of goods to customers, as an activity governed by its own technology and undertaken by firms subsequently to production operations. We then use the model to investigate how distribution shapes innovation-driven economic growth. We contrast two canonical...
