The Economics of Innovation (ECO-AD-INNOVATIO)

ECO-AD-INNOVATIO

Description

The main intention of this course is to deliver students with a working knowledge of research in this area by studying some of the canonical work, both empirical and theoretical, and then exploring some frontier work. After discussing some general background, we’ll focus in on three topics: the relationship between competition and innovation, the role and measurement of knowledge spillovers, and the impact of patent policy on innovation.

The goal is to provide students both the basis on which to identify some of the important research questions as well as an understanding of the techniques that could be employed to address them. You might notice a lot of papers in top journals in recent years; the topics covered here are very popular in the literature right now.

The papers listed below are a sample. We will not cover all of them, and we may cover some things that arise that aren’t on the list yet.

Assessment:
Each student will do an in-class presentation of a paper (this could be with one of the papers on the reading list or one chosen in consultation with me). Each student will develop and submit a research proposal. The proposal must include an introduction highlighting the research question and why it is interesting, a literature review, and a discussion of modelling possibilities and testing. The two components (paper presentation and research proposal) are weighted equally in the final grade.
