In this paper we propose a variance estimator for the OLS estimator as well as for nonlinear estimators such as logit, probit and GMM. This variance estimator enables cluster-robust inference when there is two-way or multi-way clustering that is non-nested. The variance estimator extends the...

Understanding whether criminal behavior is contagious is important for law enforcement and for policies that affect how people are sorted across social settings. We test the hypothesis that criminal behavior is contagious by using data from the Moving to Opportunity (MTO) randomized...

Inter-company production networks can improve the resource efficiency of production processes. This book shows the results of the research project „Integrated Process Design for the Inter-Company Plant Layout Planning of Dynamic Mass Flow Networks“ (PepOn). A systematic approach for process...

Understanding whether criminal behavior is "contagious" is important for law enforcement and for policies that affect how people are sorted across social settings. We test the hypothesis that criminal behavior is contagious by using data from the Moving to Opportunity (MTO) randomized...
