We revisit the identification argument of Kirkeboen et al. (2016) who showed how one may combine instruments for multiple unordered treatments with information about individuals' ranking of these treatments to achieve identification while allowing for both observed and unobserved heterogeneity...

Recent work suggests the patterns of international trade may be distorted because of information frictions. Little is known, however, about how advancements in information communication technology (ICT) affect trade patterns. The goal of our paper is to analyze how and why the adoption of such...
