Endogeneity is an important issue that often arises in discrete choice models leading to biased estimates of the parameters. We propose the extended multiple indicator solution (EMIS) methodology to correct for it and exemplify it with a case study using r ...
Supercooled liquids are characterized by their fragility: The slowing down of the dynamics under cooling is more sudden and the jump of specific heat at the glass transition is generally larger in fragile liquids than in strong ones. Despite the importance ...
This research investigates the measurement of perceptions by means of adjectives freely reported by respondents in semi-open questions. The objective of this work is to use these adjectives as indicators of perceptions in hybrid choice models (HCM) in orde ...
The study of the innovative output of organizations often relies on a count of patents filed at one single office of reference such as the European Patent Office (EPO). Yet, not all organizations file their patents at the EPO, raising the specter of a sele ...
This paper presents evidence that firms face a trade-off between the quantity and the quality of their research output. The econometric analysis uses survey data on patent applicants at the European Patent Office and addresses the identification problem ca ...
This article decomposes the R&D-patent relationship at the industry level to shed light on the sources of the worldwide surge in patent applications. The empirical analysis is based on a unique data set that includes five patent indicators computed for 18 ...
This paper reviews the economic literature on the role of fees in patent systems. Two main research questions are usually addressed: the impact of patent fees on the behavior of applicants and the question of optimal fees. Studies in the former group confi ...
Cloud computing has become pervasive due to attractive features such as on-demand resource provisioning and elasticity. Most cloud providers are centralized entities that employ massive data centers. However, in recent times, due to increasing concerns abo ...
While moving from diary survey to location-aware technologies, recent data collection techniques provide new insights about location choices. Only few dynamic models of location choice exist in the literature, and none of them to our knowledge correct for ...
This paper describes a new patent-based indicator of inventive activity. The indicator is based on counting all the priority patent applications filed by a country's inventors, regardless of the patent office in which the application is filed, and can ther ...
