Using a large administrative dataset, we perform unsupervised pattern analysis to study how borrowers repay within the framework of this loan. We identify eight clusters that can be grouped into three distinct repayment types. We show that borrowers with fluctuating incomes and limited ...

In this paper, we analyze the interdependence between the structure of transmission infrastructure and the electricity mix, applied to the case of Germany today and into the future. In particular, we are interested in how an energy system based on a high share of distributed renewable sources operates under different transmission regimes, for example, copper plate or more constrained network topologies. ...

I Am Innocent: Hourly Variations in Air Pollution and Crime Behavior

I posit that hourly changes in air pollution affect criminality through two distinct pathways, via physiological effects on the criminal and by changes in the tightness of the market for criminal activities. To disentangle individual from market effects, I develop a behavioral model of the individual decision to transgress and a model of search-and-matching frictions between criminals and crime opportunities. ...
