Knowledge spillovers in U.S. patents: a dynamic patent intensity model with secret common innovation factors

Blazsek, Szabolcs; Escribano, Alvaro - Departamento de Economía, Universidad Carlos III de Madrid - 2009

During the past two decades, innovations protected by patents have played a key role in business strategies. This fact … enhanced studies of the determinants of patents and the impact of patents on innovation and competitive advantage. Sustaining … competitive advantages is as important as creating them. Patents help sustaining competivite advantages by increasing the …

Modelling Security Market Events in Continuous Time: Intensity Based, Multivariate Point Process Models

Bowsher, Clive G. - Economics Group, Nuffield College, University of Oxford - 2005

A continuous time econometric modelling framework for multivariate financial market event (or 'transactions') data is developed in which the model is specified via the vector conditional intensity. This has the advantage that the conditioning information set is updated continuously in time as...

Extreme value models in a conditional duration intensity framework

Herrera, Rodrigo; Schipp, Bernhard - Sonderforschungsbereich 649: Ökonomisches Risiko, … - 2011

The analysis of return series from financial markets is often based on the Peaks-over-threshold (POT) model. This model assumes independent and identically distributed observations and therefore a Poisson process is used to characterize the occurrence of extreme events. However, stylized facts...

Economic growth across Chinese provinces: insearch of innovation-driven gains

Funke, Michael; Yu, Hao - 2009

In this paper we analyse the impact of R&D on total factor productivity across Chinese provinces. We introduce innovations explicitly into a production function and evaluate their contribution to economic growth in 1993 - 2006. The empirical results highlight the importance and the interaction...

Strategic Patenting and Software Innovation

Noel, Michael; Schankerman, Mark - Suntory and Toyota International Centres for Economics … - 2006

Strategic patenting is widely believed to raise the costs of innovating,especially in industries characterised by cumulative innovation. This paperstudies the effects of strategic patenting on R&D, patenting and marketvalue in the computer software industry. We focus on two key aspects:patent...

Measuring Intersectoral Technology Spillovers: Estimates from the European and US Patent Office Databases

Verspagen, Bart - In: Economic Systems Research 9 (1997) 1, pp. 47-65

This paper presents several new methods for measuring intersectoral knowledge spillovers, and applies these methods in an analysis of productivity growth in manufacturing for a cross-country, cross-sectional sample for the 1980s. It is argued that existing methods of measuring such intersectoral...

Measuring Intersectoral Spillovers: French Evidence

Meijl, Hans van - In: Economic Systems Research 9 (1997) 1, pp. 25-46

In this paper, we measure the effect of internal R&D and various spillover concepts on productivity growth, using a database for France that covers the period 1978-92. Three spillover concepts are distinguished: rent spillovers related to investment goods; rent spillovers related to intermediate...
