    The pandemic catalyzed an enduring shift to remote work. To measure and characterize this shift, we examine more than 250 million job vacancy postings across five English-speaking countries. Our measurements rely on a state-of-the-art languageprocessing framework that we fit, test, and refine using 30,000 human classifications. We achieve 99% accuracy in flagging job postings that advertise hybrid or fully remote work, greatly outperforming dictionary methods and also outperforming other machine-learning methods. From 2019 to early 2023, the share of postings that say new employees can work remotely one or more days per week rose more than three-fold in the U.S and by a factor of five or more in Australia, Canada, New Zealand and the U.K. These developments are highly non-uniform across and within cities, industries, occupations, and companies. Even when zooming in on employers in the same industry competing for talent in the same occupations, we find large differences in the share of job postings that explicitly offer remote work.

    The work by Baker et al. (2016), who propose a dictionary based method and estimate the level of economic policy uncertainty (EPU) based on the occurrence of specific terms in ten leading newspapers in the USA, is among the first ones to detect the potential of text data in economic research. Following this line of research, this paper proposes automated approaches to construction of EPU indices for different countries based on newspapers' texts. First, multilingual fastText word embeddings and BERT text embeddings are used in order to define relevant EPU key words and EPU related articles, respectively. Further, multilingual conceptualized topic modeling introduced by Bianchi et al. (2021) is performed and EPU related topics are detected. It is shown that the constructed EPU indices based on fastText embeddings Granger cause the economic activity in all of the considered countries, namely Germany, Russia, and Ukraine. Also, some of the topics uncovered by multilingual conceptualized topic modeling have proved to Granger cause the economic activity in all of the considered countries.

    Grisot G, Pennino F, Herrmann JB. Predicting sentiments and space in Swiss literature using BERT and Prodigy. Presented at the CHR2023 - 3rd Conference on Computational Humanities Research, Antwerp. ; Thanks to the development of new powerful technologies for computational data analysis, an increasing number of researchers has investigated sentiment in texts, making use of traditional corpus linguistic approaches as well as machine learning tools. When considering literary texts, however, sentiment analysis is still in its infancy, especially when it focuses on languages other than English [1]. Crucially, only very few studies so far have related the representation of sentiment and emotions to that of space. This has depended partly on the limited amount of literary texts available digitally and partly of the challenges of defining and identifying space in literature. Emotions and space are however central to the experience of literary narrative [2, 3, 4], and recent advances in their systematic, quantitative analysis have been made within computational literary studies [5, 6, 7]. Using lexicon-based methods, Grisot and Herrmann [8] investigated emotions and sentiments in relation to the representation of literary space, looking in particular at the differences between the rural and urban landscapes portrayed in a corpus of Swiss novels written in German. The present paper takes a step forward, building on their data and using manual annotation and advanced machine learning methods to train a fine-tuned model, in order to automatically detect and recognise on the one hand sentiment (valence, arousal) and discrete emotions (joy, anger, sadness, disgust, fear, surprise), and on the other spatial entities (named and unnamed), in a historical corpus of Swiss novels. With such model, we aim at higher levels of lexical coverage and validity when compared to existing results obtained with sentiment lexicons and entities lists. Using a language model trained on a large corpus (3000+) of German literary texts spanning ...
