Essays on the strategic role of message consistency in employer branding and omni-channel-recruiting
No full textAmid intensifying talent competition, this dissertation investigates how message consistency shapes employer branding and recruitment. Essay 1 maps omnichannel communication for 118 firms across five industries (about 19,400 texts from websites, LinkedIn, Facebook, and Glassdoor) using Transformer-based measures of semantic consistency and cultural signals. It documents substantial within-channel and cross-channel inconsistencies, with systematic variation by platform and industry.
Essay 2 combines an online experiment (N = 510) and a field study of 1,056,696 job ads. Consistency levels were manipulated across website, LinkedIn, and Glassdoor texts. Low consistency reliably worsened symbolic employer brand image and attractiveness, while high consistency showed diminishing returns and effects moderated by prior brand image. Using MPNet-based semantic metrics, higher within-ad and across-ad consistency predicted shorter time-to-hire, controlling for job and firm factors.
The work reframes consistency as a calibrated, context-dependent lever for employer branding and recruiting efficiency

Biodiversity Engel Curves : estimating how income and inequality shape consumption-driven biodiversity loss
No full textWe examine the relationship between household incomes and the biodiversity footprints of consumption in the United States from 1996 to 2022. Combining detailed household expenditure surveys with environmentally-extended multi-regional input-output accounting methods, we calculate consumption-based (i) land-use and (ii) species-loss footprints as proxies for overall biodiversity pressure. We find thatthe average biodiversity footprints of US households declined between 1996 and the early 2010s but began increasing again thereafter, as rising consumption pressure outpaced technological improvements. To characterize the relationship between household income and biodiversity footprints, we construct Environmental Engel Curves (EECs). Just like aggregate footprints, EECs shifted downwards until the early 2010s but have moved upwards in recent years, mainly due to a more biodiversity-intensive composition of expenditures, as we show. Moreover, EECs for land use are concave, implying a “biodiversity-equality trade-off” of moderate size. In 2022, full redistribution to achieve perfect income equality would have raised aggregate land use by 3.2% all else equal, calling for additional efforts to maintain a given biodiversity conservation goal
