The Impact of Spillovers and Knowledge Heterogeneity on Firm Performance: Evidence from Swiss Manufacturing

This chapter explores the impact of knowledge capital (computed on the basis of firm patent counts and R&D expenditures, respectively) and patent, as well as R&D spillovers, on total factor productivity at the firm level for Swiss manufacturing in the usual setting of a Cobb-Douglas production function. We introduce spillovers from R&D or patents by constructing two types of spillover measures: one based on material flows between sectors, and the other one reflecting technological proximity at the firm level. In a further step, international R&D as well as patent spillovers from eight technologically highly developed countries are taken into consideration.
