Employment protection, international specialization, and innovation

We develop a model to analyze the implications of "ring costs on incentives for R&D and international specialization. The key idea is that countries with a rigid labor market will tend to produce relatively secure goods, at a late stage of their product life cycle. Consequently, their researchers tend to specialize in &secondary innovation' which improves existing products, rather than &primary innovation' which introduces new products. This is roughly consistent with the observed pattern of R&D in Europe versus the U.S. Employment protection does not necessarily harm the country where it prevails, but typically reduces world welfare and the world number of goods. 2002 Elsevier Science B.V.
