In this paper we estimate the dynamic relationship between resources used in R&D by some OECD countries and their innovation output as measured by patent applications. We first estimate a long-run cointegration relation using recently developed tests and panel estimation techniques. We find that...

In this paper we estimate the dynamic relationship between employment in R&D and generation of knowledge as measured by patent applications across OECD countries. In several recently developed models, known as 'idea-based' models of growth, the afore mentioned ideagenerating process is the...

This article shows - on both conceptual and empirical grounds - the importance of business cycles in affecting key relationships between innovation and international performance. While periods of upswing are characterised by a well documented 'virtuous circle'. between innovation inputs, new...

We analyze the impact of obsolescence of economic inventions by incorporating maintenance costsin the endogenous growth model of expanding product varieties. This contrasts with the existingliterature, which ignores maintenance costs and uses the model of quality improvements todescribe...

We examine the impact of the strictness of employment protection legislation on innovation intensity. To this purpose, we use a panel of annual data from OECD countries over the period 1990-1999 and estimate difference-in-difference models to explain the variation of innovation intensity between...

We also show that the evidence that knowledge spillovers flow along the supply chains is more robust than the traditional finding that knowledge spillovers depend on geographical distance or trade flows. Our findings support policies that favour participation in supply chains to foster economic...

This volume was prepared by Sebastian Benz while he was working at the Ifo Institute. It was completed in December 2013 and accepted as a doctoral thesis by the Department of Economics at the University of Munich. It includes five self-contained chapters. All chapters discuss different...

Recent evidence on world trade patterns reveals North-South specialization across products of the same industries and product groups but different quality, which is not matched by the predictions of traditional and new trade theory. This paper analyzes a model of North-South trade and endogenous...
