This paper estimates the effect of home high-speed internet on national test scores of students at age 14. We combine comprehensive information on the telecom network, administrative student records, house prices and local amenities in England in a fuzzy spatial regression discontinuity design across invisible telephone exchange catchment areas. Using this strategy, we find that increasing broadband ...

Panel attrition poses major threats to the survey quality of panel studies. Many features have been introduced to keep panel attrition as low as possible. Based on a random sample of refugees, a highly mobile population, we investigate whether using a mobile phone application improves address quality and response behavior. Various features, including geo-tracking, collecting email addresses and adress ...
We provide an evaluation of the impact of public subsidy schemes that aimed to support the development of basic broadband infrastructure in rural areas of Germany. Such subsidies are subject to state aid control by the European Commission (EC). While the EC increasingly recognises the role of economic analysis in controlling public aid to companies, there are to date no full retrospective studies performed ...
Offshore wind plays an ever-increasing role for the global transition to renewable energy. For offshore wind energy to be successful, cost-effective transport of the produced electricity to shore is necessary. The development and operation of the offshore transmission asset is costly and regulated differently across the globe. In most countries, the TSO is responsible for the transmission and develops ...
This paper presents a broad retrospective evaluation of mergers and merger decisions in markets dominated by multisided digital platforms.

We cluster target companies on their area of economic activity providing suggestive evidence on the strategies behind these mergers. ...
Large-scale data show promise to provide efficiency gains through individualized risk predictions in many business and policy settings. Yet, assessments of the degree of data-enabled efficiency improvements remain scarce. We quantify the value of the availability of a variety of data combinations for tackling the policy problem of curbing antibiotic resistance, where the reduction of inefficient antibiotic ...
