Privacy and False Identification Risk in Geomasking Techniques

Recent years have seen an increase in location privacy research, including the application of geomasking procedures. Geographical masks aim to protect privacy and preserve spatial information through the displacement of point data. False identification, or the mistaken association of data with the incorrect person or household, is an unexplored issue in geomasking, despite legal protections against false association. This study introduces a topological framework for assessing identification risk and examines the risk of false identification in four masking techniques: random perturbation, donut masking, and the newer Voronoi and MGRS masking techniques. While Voronoi masking is found to best preserve the clustering properties of a sample of urban foreclosure data, the other three masking techniques result in better protection against correct and false identification.     

What Kind of Entrepreneurship Drives Regional Development in European Non-core Regions? A Literature Review on Empirical Entrepreneurship Research

Regional policies across Europe aim at stimulating regional development in non-core regions through fostering entrepreneurship. However, the policies applied in non-core regions and the concepts of entrepreneurship these policies are based on differ. Therefore, the goal of this review is to identify different understandings of entrepreneurship and their role for regional development processes in European non-core regions. To this end, empirical studies investigating entrepreneurship in European non-core regions from 1999 to 2011 were analysed. The results of the analysis are presented along three drivers and outcomes of entrepreneurship identified inductively from the literature: innovation, social capital and institutional change. We made out seven different types of entrepreneurship in European non-core regions. These seven types of entrepreneurship comprise particular mechanisms through which they stimulate regional development. Further research should study the interplay between these different mechanisms of regional development in non-core regions which may induce a more territorial approach to understand entrepreneurship in non-core regions across Europe.     

What's in a Name? Extracting Econometric Drivers to Assess The Impact of National Park Designation*

Public land designations are often primarily political decisions that may also have substantial local economic impacts. This paper econometrically estimates the visitation effect of the conversion of National Monuments to National Parks through the eight designation changes that have occurred between 1979 and 2000. The study finds robust and significant impacts of such conversions, yielding 11,642 additional visitors annually, even after controlling for likely site acreage expansion and other site visitation trends. Furthermore, these new visitors do not appear to occur at the expense of visitation at alternative sites. Using these findings, the paper explores the local economic impact of the Great Sand Dunes conversion on Colorado's San Luis Valley.
