A large body of research across management, psychology, accounting, and economics shows that subjective performance evaluations are systematically biased: ratings cluster near the midpoint of scales and are often excessively lenient. As organizations increasingly adopt large language models...

This paper studies the causal impact of language skills on human capital accumulation, labor market outcomes, and job characteristics of childhood immigrants across European countries. Using PIAAC data, we adopt an instrumental variable strategy based on the critical age hypothesis and...

In this paper, we present an approach to relate typological measures of language complexity (based on the grammars of different languages) with empirical measures of that complexity (based on actual texts). It is known as the "structure-conduct-performance paradigm", and we have taken it from...

Politicians can adjust the complexity of their communication to signal different things to different audiences: more complex language can indicate competence, while lower complexity may bring them closer to "common people". These strategic shifts in complexity, however, remain understudied. We...

In this paper, we investigate the relationship between language background and labour market outcomes in the bilingual labour market of the Spanish region of Catalonia. The empirical analysis draws on repeated cross-sectional data that allow us to construct a quantitative measure of linguistic...

This article presents an evaluation of Mate Raymi, an educational program designed to strengthen mathematical and ethnomathematical skills among preschool children in Peru. Implemented through audio lessons and complemented with contextualized materials, teacher training, and pedagogical...

This paper evaluates a randomized remote tutoring program implemented in Paraguay, targeting 1,650 students in grades four through six with low baseline performance in Spanish language. The intervention provided two weekly 30-minute one-on-one tutoring sessions over the phone for eight weeks,...

This study presents the results of an experimental evaluation of a pedagogical intervention based on the mobile application Quechua Collao, designed to strengthen Quechua language skills as a second language among primary and secondary school students in public schools with an Intercultural...

In this article, we evaluate the impact of a targeted fee subsidy program that reduced the registration cost of the Caribbean Secondary Education Certificate (CSEC) Spanish exam-a standardized regional assessment for high school leavers seeking to demonstrate language proficiency. The subsidy...

We examine whether sycophantic AI advice distorts decisions. Our experiment involves 1,500 participants in 30 decision environments spanning core domains in economics and the social sciences. Contrary to the vast majority of predictions in an expert survey we conduct, we find that AI advice...

We conducted a controlled experiment to study how different gender frames used in the instructions affect economic behavior. In our experiment, we systematically varied the framing of the instructions, either using the male, the female, or a gender-inclusive form. Participants played three...

In this paper we deliver first causal evidence on the relationship between immigrant host country language proficiency and homeownership. Using an instrumental variable strategy, we find a substantial positive impact of language skills on the propensity to own a home and the quality of housing....
