This article compares the relationship between patent quality and patent value in discrete and cumulative innovation. Using factor analysis and a set of various commonly used patent quality indicators including claims, citations and family size, we build a quality factor jointly driving all indicators for 9255 patents. We then test the significance of this quality factor for predicting patent r...

We describe the properties of (t,m, s)-nets and Halton draws. Four types of (t,m, s)-nets, two types of Halton draws, and independent draws are compared in an application of maximum simulated likelihood estimation of a mixed logit model. All of the quasi-random procedures are found to perform far better than independent draws. The best performance is attained by one of the (t,m, s)-nets. The pr...

This study makes use of the results of a postal questionnaire sent to a sample of large private sector companies in Britain and France to address two key issues in the new institutional analysis of the firm. The first is the way the institutional environment supports and constrains the design of firm-level organisational devices and governance mechanisms. The second concerns the relation betwee...

The purchasing behaviour of consumers is often influenced by numerous factors, including the visibility of the products and the influence of other customers through their own purchases or their recommendations. Motivated by trial-offer and freemium markets and a number of online markets for cultural products, leisure services, and retail, this paper studies the dynamics of a marketplace ran by ...

We estimate revealed willingness to pay for animal welfare using a panel mixed logit model. We utilize a unique household level panel, combining real purchases with survey data on perceived public and private good attributes of different types of eggs. We estimate willingness to pay for organic eggs controlling for trust in a positive connection between the public good animal welfare and the or...

In the Netherlands, there is currently both a quantitative and a qualitative shortage in student housing. New housing units need to be built to accommodate the growing population of students, and existing ones need to be adapted to better fit the students’ needs. However, whilst housing preferences are studied extensively in the literature, less research has focused on the housing needs of stud...

Female Labor Market Transitions in Europe Using micro panel data, labor market transitions are analyzed for the EU-member states by cumulative year-by-year transition probabilities. As female (non-)employment patterns changed more dramatically than male employment in past decades, the analyses mainly refer to female labor supply. In search for important determinants of these transitions, six EU...

This paper analyzes pedestrian injury severity from automobile crashes at signalized intersections in a medium-size city. It estimates an ordered logit model of injury severity and finds that vehicle type, gender, land-use, speed limit, traffic volume, the presence of sidewalks and visual-obstruction significantly explain pedestrian injury severity in vehiclepedestrian crashes at signalized int...

Emergency Department (ED) triage is a process of determining illness severity and accordingly assigning patient priority. The Emergency Severity Index (ESI) is a 5-level acuity categorization system that aides in triage. This paper compared the capabilities of predicting ESI level using ordinal logistic regression (OLR), artificial neural networks (NNs), and naïve Bayesian networks (NBNs). Data...

This study introduces dynamic features into the random-utility-based multiregional input-output (RUBMRIO) model. The RUBMRIO model predicts interzonal trade and travel patterns, as well as business and household location choices, using consumption and production process data. It equilibrates production and trade, labor markets and transportation networks simultaneously. Multinomial logit models...
