Most studies on corporate governance recognize endogeneity in the nexus between corporate governance and financial performance. Little attention has, however, been paid to the direction of causality between the two phenomena, and hence the Vector Error Correction (VEC) model, which allows for...

Any serious empirical study of factor substitutability has to allow the data to display complementarity as well as substitutability. The standard approach reflecting this idea is a translog specification - this is also the approach used by numerous studies analyzing the relative capital-skill...

Amazon's Free App of the Day program, aimed at improving app visibility using daily free promotions, is a compelling experiment in the ‘economics of free'. In this study, we investigate the longer-term consequences of free app promotions on the performance of apps on Amazon Appstore. In...

This paper compares technologies across space and time on the basis of factual and counterfactual substitution elasticities and argues that differences in estimated substitution elasticities should be decomposed into two counterfactual components. While the first component is designed to...

The scientific environment might influence university researchers’ job designs. In a principal–agent model, researchers must choose between substitutable tasks, publishing or teaching, according to their individual abilities and the scientific and pedagogical context that exists in their...

In this paper, a subsystem of demand equations is estimated using data from the Norwegian survey of household expenditures 1989-1991. One objective has been to obtain substantial knowledge of Norwegian household demand for a set of food groups, with emphasis on price responses, using two...
