Demand Estimation with Text and Image Data
The RAND Journal of Economics, EarlyView.ABSTRACT We propose a demand estimation approach that leverages unstructured data to infer substitution patterns. Using pre‐trained deep learning models, we extract embeddings from product images and textual descriptions and incorporate them into a mixed logit demand model.

The electoral politics of immigration and crime
American Journal of Political Science, EarlyView.Abstract Concern that immigration worsens crime problems is prevalent across Western publics. How does it shape electoral politics? Prior research asserted a growing left–right divide in immigration attitudes and voting behavior due to educational realignment.

American Journal of Political Science, EarlyView.Abstract Existing literature posits that attitudes toward immigration are shaped by the impact of migrants on native workers' wages and employment, as well as by various other material, cultural, and social concerns. However, empirically disentangling these influences can be challenging.

Business Ethics, the Environment &Responsibility, EarlyView.ABSTRACT Despite research on sustainable labels, little is known about combining eco‐ and social labels and the effects on consumers. Although consumers are increasingly confronted with both socially oriented, e.g., fair trade, as well as environmentally oriented eco‐labels such as certified organic cotton, the effect on consumer value has not been ...

“Yet the Problem Remains”: Why Genetic Determinism Still Haunts Biomedical Research
Bioethics, EarlyView.ABSTRACT After the horrors of the Holocaust and its connections to eugenics were revealed to the world, many post‐war population geneticists sought to establish rhetorical distance from the Nazi's state‐led campaigns, without abandoning their belief that actively shaping the population's genetics would produce a prosperous society.

Identifiability conditions in cognitive diagnosis: Implications for Q‐matrix estimation algorithms
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract The Q‐matrix of a cognitively diagnostic assessment (CDA), documenting the item‐attribute associations, is a key component of any CDA. However, the true Q‐matrix underlying a CDA is never known and must be estimated—typically by content experts.

British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Although full‐information maximum likelihood (FIML) estimation is widely used for diagnostic classification models (DCMs), its computational efficiency deteriorates sharply in high‐dimensional settings. This scalability challenge is increasingly critical as DCMs are applied to large‐scale assessments, psychological testing and longitudinal ...

Evaluating Encodings for Bivariate Edges in Adjacency Matrices
Computer Graphics Forum, EarlyView.Abstract We present the first empirical evaluation of techniques for encoding distributions of quantitative edge values within adjacency matrices. In many real‐world networks, edges represent not a single value but a set of measurements. While adjacency matrices preserve structural clarity, their compact cells limit the simultaneous display of multiple
