This study is the first to estimate the effects of the sending-off of a player on the full time results in international club soccer. To this end, we analyse data of more than 2,000 recent games in the UEFA Champions League and UEFA Europa League. We find that when home teams receive a red card,...

We investigate whether the home advantage in soccer differs by various dimensions of distance between the (regions of the) home and away teams: geographical distance, climatic differences, cultural distance, and disparities in economic prosperity. To this end, we analyse 2,012 recent matches...

We are the first to investigate whether the introduction of additional assistant referees in the UEFA Europa League (in season 2009-2010) and the UEFA Champions League (in season 2010-2011) was associated with lower referee bias. To this end, we analyse a unique database with pre- and...

We test the soccer myth suggesting that a particularly good moment to score a goal is just before half time. To this end, rich data on 1,179 games played in the UEFA Champions League and UEFA Europa League are analysed. In contrast to the myth, we find that, conditional on the goal difference...

The current peer review system suffers from two key problems: promotion of an in-crowd whose methods, opinions and innovations it protects; and failure to represent the opinions and interests of non-peer clients. As a result, whole disciplines orient themselves toward navel-gazing research...

In this paper we investigate how the expulsion of a player influences the outcome of a football match. Common sense implies a negative impact for the affected team. However, an old football myth suggests that such an expulsion might also be beneficial since it increases the team spirit as well...

Causal inference in the empirical sciences is based on counterfactuals. This paper presents the counterfactual account of causation in terms of Lewis's possible-world semantics, and reformulates the statistical potential outcome framework and its underlying assumptions using counterfactual...

We present the first systematic review of the scientific literature on smartphone use and academic success. We synthesise the theoretical mechanisms, empirical approaches, and empirical findings described in the multidisciplinary literature to date. Our analysis of the literature reveals a...

Despite academic scepticism, cluster policies remain popular with policymakers. This paper evaluates the causal impact of a flagship UK technology cluster programme. I build a simple framework and identify effects using difference-in-differences and synthetic controls on rich microdata. I...

How the internet affects job matching is not well understood due to a lack of data on job vacancies and quasi-experimental variation in internet use. This paper helps fill this gap using plausibly exogenous roll-out of broadband infrastructure in Norway, and comprehensive data on recruiters,...
