Abstract

We demonstrate that R&D intensity is an appropriate measure of vertical differentiation, while the Rauch (J Int Econ 48:7–35, 1999) classification mainly captures horizontal differentiation. Product market characteristics vary considerably across R&D intensity-based “technology levels” of the OECD-STI taxonomy, as well as across categories of the Rauch classification. Both high technology and differentiated products display lower price elasticity of demand and longer quality ladders than do low technology and homogeneous products. However, variety proliferation decreases with the technology level and increases with the Rauch category, while price dispersion increases with technology but not with the Rauch. Additionally, Rauch categories do not differ in factor intensities, while higher tech industries are more capital intensive than lower tech ones.

从水平分化中分离垂直分化

我们证明研发强度是垂直分化的适当衡量标准，而Rauch (J Int Econ 48:7-35, 1999)分类主要捕捉水平分化。产品市场特征在OECD-STI分类中基于研发强度的“技术水平”之间以及Rauch分类的不同类别之间差异很大。高技术和差异化产品都比低技术和同质化产品表现出更低的需求价格弹性和更长的质量阶梯。品种扩散随技术水平而降低，随劳赫类别而增加;价格分散随技术水平而增加，但不随劳赫类别而增加。此外，Rauch分类在要素强度上没有差异，而高技术产业比低技术产业的资本密集程度更高。

期刊介绍： New Online Manuscript Submission System The Review of Industrial Organization publishes research papers on all aspects of industrial organization, broadly defined. A main focus is on competition and monopoly, in their many forms and processes and their effects on efficiency, innovation, and social conditions. Topics may range from the internal organization of enterprises to wide international comparisons. The Review is also increasing its interest in papers on public policies such as antitrust, regulation, deregulation, public enterprise, and privatization. Papers may deal with any economic sectors and any developed economies. The Review continues its primary interest in ideas that can be verified by econometric evidence, case studies, or other real conditions. But the Review also seeks papers that advance significant theories of industrial organization and policy. Papers using abstract techniques and econometric tests should present the methods and analysis in plain enough English so that non-specialist readers can evaluate the content. The Review welcomes submissions from any source, and the Editors will make every effort to have papers reviewed quickly and to give prompt decisions. The Editors will also seek to arrange symposia on specific topics, and they are open to proposals for grouped papers. They also welcome shorter notes and commentaries on topics of interest to the profession. Officially cited as: Rev Ind Organ
