    <summary type="text">Title: Spatial unit roots in regressions: A practitioner's guide and a stata package
Authors: Becker, Sascha O.; Boll, P. David; Voth, Hans-Joachim
Abstract: Spatial unit roots can lead to spurious regression results. We present a brief overview of the methods developed in M&amp;#x00a8;uller and Watson (2024) to test for and correct for spatial unit roots. We also introduce a suite of Stata commands (-spur-) implementing these techniques. Our commands exactly replicate results in M&amp;#x00a8;uller and Watson (2024) using the same Chetty et al. (2014) data. We present a brief practitioner's guide for applied researchers.</summary>

    <summary type="text">Title: The rise of China and the global production of scientific knowledge
Authors: Ku, Hyejin; Mu, Tianrui
Abstract: This paper examines how China's growing research capabilities impact global research universities across scientific fields. Using bibliometric data from 1980 to 2020, we assess the effects of the "China shock" on high-impact publications, novel concepts, and citation patterns. Our analysis reveals a positive net effect in Chemistry and Engineering &amp; Materials Science (EMS), but a negative effect in Clinical &amp; Life Sciences (CLS). In other fields, the effects are mostly positive but imprecise. We highlight the coexistence of competition and spillover effects, with their relative strength shaped by field characteristics, such as expansion potential and the quality of China's research.</summary>

Authors: Luo, Qinyue; Zhang, Liaoliang; Zhang, Xinhan
Abstract: We analyze explicit age discrimination in hiring decisions and job seekers' responses in the Chinese labor market, using a large-scale dataset of job postings with ad-level group characteristics of applicants. In nearly 48% of postings, employers explicitly exclude certain age groups, with significant variation across firm types, sizes, industries, and occupations. We show that employers' explicit age requests are shaped by statistical and taste-based discrimination reflected in job skill requirements and ageist language, as well as constraints such as expected processing costs, and competition in labor demand. Our findings align with a labor demand model where employers decide whether to consider (undesired) candidates from an additional age group based on their search factors and preferences. On the supply side, we leverage the distribution of applicant characteristics such as age and education level to show that age requirements are interpreted as signals rather than strict barriers. Nonetheless, explicit age restrictions substantially alter the applicant pool by attracting younger applicants while discouraging skilled workers.</summary>

    <summary type="text">Title: How do firms respond to parental leave absences?
Authors: Brenøe, Anne Ardila; Krenk, Urésa; Steinhauer, Andreas; Zweimüller, Josef
Abstract: How do firms adjust their labor demand when a female employee takes temporary leave after childbirth? Using Austrian administrative data, we compare firms with and without a birth event and exploit policy reforms that significantly altered leave durations. We find that (i) firms adjust hiring, employment, and wages around leave periods, but these effects fade quickly; (ii) adjustments differ sharply by gender, reflecting strong gender segregation within firms; (iii) longer leave entitlements extend actual leave absences but have only short-term effects; and (iv) there is no impact on firm closure up to five years after birth.</summary>
