Abstract

This thesis consists of four self-contained chapters. In the first chapter, written together with Rajkamal Iyer, Thais Jensen, and Niels Johannesen, we provide empirical evidence of the distortive effects of too-big-to-fail guarantees on bank competition for retail deposits. In the second chapter, written together with Asger Lau Andersen, Amalie Sofie Jensen, Niels Johannesen, Claus Thustrup Kreiner, and Søren Leth-Petersen, we provide precise and comprehensive evidence on how households respond to unemployment shocks by linking multiple high-frequency administrative data sets from government agencies, covering the entire Danish population, with transaction-level data from a major bank. In the third chapter, written together with Asger Lau Andersen, and Niels Johannesen, we combine transaction-level customer records from a large retail bank with government registers in order to construct a unique dataset with high-frequency information on income, spending, and intra-family bank transfers and we use these data to produce new evidence on intra-family insurance. In the fourth and final chapter, I demonstrate how the increasing popularity of mobile money transfer apps is generating population-scale data on real world social interactions, presenting researchers with an opportunity to better comprehend social networks and their role in social and economic behavior.
