In this case study, we examine a novel aspect of data collected in a typical probability and a typical nonprobability panel: mobile app data. The data were collected in Great Britain in 2018, using the Innovation Panel of the UK Household Longitudinal Study and the Lightspeed online access panel. Respondents in each panel were invited to participate in a month-long study, reporting all their daily ...

This motivates a laboratory experiment to study causality behind these effects. In two experiments, ...

Next, I exploit the variation in brand ownership caused by a large merger, cleared conditional on divestiture, in the U.S. deodorant market, to quantify the extent to which divestitures...
