What accounts for the diversity and limited concentration that has long characterized the organization of the advertising agency industry? This question is addressed by treating an advertising agency as a multiproduct firm. The firm's product line or service mix is defined in terms of the set of...

This paper examines the impact of government assistance through R&D grants on innovation output for firms in New Zealand. Using a large database that links administrative and tax data with survey data, we are able to control for large number of firm characteristics and thus minimise selection...

This paper emphasizes the different nature of cross border liberalization in network related services, such as telecoms, compared to liberalization in goods. In the presence of network externalities, it argues that if two disjoint country service networks involving a small and large country are...

This paper quantifies the roles of increases in the demand for skill-intensive output, the efficient scale of service production, and female labor supply in the growth of services. We extend the Buera and Kaboski (2012a,b) model to a two-person household, incorporating a joint decision on home...

Startups in IT and life sciences appear to be flourishing. However, startups in other sectors, such as new materials, automation, and eco-innovations, which are often called "deep tech", seem to struggle. We argue that innovations with both technical and commercial challenges, typical of deep...

We study how the inventive capability of a firm conditions its participation in a division of innovative labor.

This paper examines the relation between ownership, corporate form, and innovation for a cross-section of private and publicly traded innovating firms in the US and 15 European countries. A striking novel observation emerges from our analysis: while most innovating firms in the US are publicly...

This paper considers the impact of the intellectual property (IP) system on the timing of cooperation/licensing by start-up technology entrepreneurs. If the market for technology licenses is efficient, the timing of licensing is independent of whether IP has already been granted. In contrast,...

Crowdsourcing is an emerging technology where innovation and production are sourced out to the public through an open call. At the center of crowdsourcing is a resource allocation problem: there is an abundance of workers but a scarcity of high skills, and an easy task assigned to a high-skill...
