After 2010, inequality returned to the level of 2000. About half of the recent decrease is due to the introduction of the national minimum wage in 2015. While employment effects of the minimum wage are negligible, we find strong wage increases among the existing workforce. The minimum wage lowered wage inequality within eastern and western Germany but also led to a convergence of the east-west wage differential. The increased labor incomes were not offset by decreasing social benefits.","PeriodicalId":48308,"journal":{"name":"Journal of Labor Economics","volume":"41 1","pages":"813 - 857"},"PeriodicalIF":3.8,"publicationDate":"2022-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42924038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, four species of PCV (PCV1 to 4) have been identified but only PCV2 has been associated firmly with disease in pigs. The objective of this study was to assess the prevalence of PCV2 and PCV3 in the wild boar population in Basilicata region, Southern Italy, since this region is characterized by large forested and rural areas and the anthropic pressure is lower than in other Italian regions. Liver samples from 82 hunted wild boar were collected in 2021 from 3 different hunting districts. Sixty (73%, 95%CI: 63-82) samples tested positive for PCVs by quantitative PCR. In detail, 22 (27%, 95%CI: 18-37) were positive for PCV2, 58 (71%, 95%CI: 60-79) for PCV3, and 20 (24.4%, 95%CI 16-35) for both PCV2 and PCV3. On genome sequencing, different types and sub-types of PCV2 and PCV3 were identified, remarking a genetic diversity and hinting to a global circulation for the identified PCV strains. Overall, the high prevalence suggests that PCV2 and PCV3 infections are endemic in the wild boar population, posing risks for semi-intensive and free-range pig farming, typical of this region, due to contact with PCV-infected wild boar.</p>","PeriodicalId":48308,"journal":{"name":"Journal of Labor Economics","volume":"23 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2022-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9031215/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82394959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While his research extended into many different areas, including environmental economics,macroeconomics, and behavioral economics, he identifiedfirst and foremost as a “labor economist.”Hewas a labor economist par excellence, always pushing the field in a new (or long overlooked) direction while maintaining the highest standards for the quality and credibility of his empirical findings. The papers in this issue, written by his students and colleagues in labor economics, pay tribute to some of his major contributions to our field. Virtually every paper builds on one or more of Alan’s ideas. Alan earned his bachelor’s degree in industrial and labor relations from Cornell in 1983. His early education included classes in labor economics and statistics that informed his work throughout his career, including a deep appreciation of the value of original data. Thiswas reflected in the surveys at the heart of many of his best-known papers—including his studies of minimum wages (Katz and Krueger 1992; Card and Krueger 1994), twins (Ashenfelter and Krueger 1994), well-being (Kahneman et al. 2004), and wage posting (Hall and Krueger 2012)—and by his founding of the Survey Research Center at Princeton in 1993. Alan’s 1987 dissertation at Harvard focused on wage determination—a topic he returned to often. The first chapter, which was his job market paper and was later published in theQuarterly Journal of Economics (Krueger 1991), is remarkable for the bold simplicity of its design.

As these AI-exposed establishments adopt AI, they simultaneously reduce hiring in non-AI positions and change the skill requirements of remaining postings. While visible at the establishment level, the aggregate impacts of AI-labor substitution on employment and wage growth in more exposed occupations and industries is currently too small to be detectable.","PeriodicalId":48308,"journal":{"name":"Journal of Labor Economics","volume":"40 1","pages":"S293 - S340"},"PeriodicalIF":3.8,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47011317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
