Drawing on a Schumpeterian (R&D-based) growth model that incorporates both tangible and intangible capital and using historical data for 21 OECD countries, we find the...

In this paper we study optimal price setting by a seller that offers a supposedly higher-quality product in a market where a good of standard quality is already available. Consumers do not directly observe the quality of the product and their purchasing decisions are distorted by salient...

This research sheds light on the role of multinational production on the type of innovation performed by firms. We construct matched firm-patent data to measure the scope of innovation, that is the extent to which the output of R&D can be spread across different product lines. We focus on two...

Based on the main insights of Schumpeterian growth theory, this paper investigates which R&D-based mechanism is better suited for explaining the pattern of world’s productivity growth. Using post-WWII data for a global sample of 115 countries, we estimate the relationship between productivity...
