The tremendous growth of digital transactions has profoundly affected the way we interact, opening vast opportunities to improve our lives. Consumers have benefited from an unprecedented proliferation of new services and products that previously were simply too costly to be developed and marketed to customers. These digital interactions create vast amounts of data. While firms are already using...
Abstract: User generated content is increasingly substituting content created by professionals.

We study a network of 122 local Austrian newspapers operating a hybrid model of citizen and professional journalism. We first...

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 assert that air pollution from nitrogen oxides affects the productivity of employees in Mexican court hearings. This is the first article analyzing this connection and the first to disentangle work-breaks from the productivity of white-collar workers. I merge hourly pollution with granular hearing data under the assumption that the length of the hearing approximates productivity and identify causality ...

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. ...
