Incidence and Growth of Patent Thickets - The Impact of Technological Opportunities and Complexity
Harhoff, Dietmar; von Graevenitz, Georg; Wagner, Stefan - C.E.P.R. Discussion Papers - 2008
patenting in complex and discrete technologies. The model captures how competition for patent portfolios and complementarity of … patents affect patenting incentives. We show that lower technological opportunities increase patenting incentives in complex … technologies while they decrease incentives in discrete technologies. Also, more competitors increase patenting incentives in …

Corporate Efficiency in Europe
Hanousek, Jan; Kocenda, Evzen; Shamshur, Anastasiya - C.E.P.R. Discussion Papers - 2015
Using a stochastic frontier model and a comprehensive dataset, we study factors that affect corporate efficiency in Europe. We find that (i) larger firms are less efficient than smaller firms, (ii) greater leverage contributes to corporate efficiency, and (iii) high competition is less...

Time-series and Cross-section Information in Affine Term Structure Models
de Jong, Frank - C.E.P.R. Discussion Papers - 1999
In this paper we provide an empirical analysis of the term structure of interest rates using the affine class of term structure models introduced by Duffie and Kan. We estimate these models by combining time-series and cross-section information in a theoretically consistent way. In the...

The Dynamics of Local Employment in France
Combes, Pierre-Philippe; Magnac, Thierry; Robin, Jean-Marc - C.E.P.R. Discussion Papers - 2003
This Paper studies the impact of local economic structure on local sectoral employment growth. Local employment growth is decomposed into ‘internal’ growth (the growth of the size of existing plants) and ‘external’ growth (the creation of new plants). Using panel data methods, we...

Participation Behaviour of East German Women After German Unification
Bonin, Holger; Euwals, Rob - C.E.P.R. Discussion Papers - 2002
The Paper studies the determinants of labour force participation by East German women after unification. To isolate the role of preferences on labour force participation from individual characteristics, we develop a panel data model that simultaneously explains participation, employment and...

Ownership and Firm Performance After Large-Scale Privatization
Kocenda, Evzen; Svejnar, Jan - C.E.P.R. Discussion Papers - 2003
We analyse the effect of ownership on post-privatization performance in a virtually complete population of medium and large firms privatized in a model large-scale privatization economy (Czech Republic). We find that concentrated foreign ownership improves economic performance, but domestic...

Model-based Clustering of Multiple Time Series
Frühwirth-Schnatter, Sylvia; Kaufmann, Sylvia - C.E.P.R. Discussion Papers - 2004
We propose to use the attractiveness of pooling relatively short time series that display similar dynamics, but without restricting to pooling all into one group. We suggest estimating the appropriate grouping of time series simultaneously along with the group-specific model parameters. We cast...

Direct Estimation of the Risk Neutral Factor Dynamics of Affine Term Structure Models
Bams, Dennis; Schotman, Peter C - C.E.P.R. Discussion Papers - 1998
This paper proposes a panel data framework for tests of affine models of the term structure of interest rates which cover equilibrium (or endogenous) models as well as extended (or exogenous, evolutionary) models. The econometric model pools yield curve data for different moments in time. Since...

A Dynamic Analysis of the Demand for Health Insurance and Health Care
Bolhaar, Jonneke; Lindeboom, Maarten; van der Klaauw, Bas - C.E.P.R. Discussion Papers - 2008
We investigate the presence of moral hazard and advantageous or adverse selection in a market for supplementary health insurance. For this we specify and estimate dynamic models for health insurance decisions and health care utilization. Estimates of the health care utilization models indicate...

Explaining the Growth of Part-Time Employment: Factors of Supply and Demand
Euwals, Rob; Hogerbrugge, Maurice - C.E.P.R. Discussion Papers - 2006
Using the Dutch Labour Force Survey 1991-2001, the authors investigate the incidence of part-time employment in the country with the highest part-time employment rate of the OECD countries. Women fulfil most part-time jobs, but a considerable fraction of men works part-time as well. Evidence...
