Title:
Socioeconomic Decline and Death: Midlife Impacts of Graduating in a Recession
Abstract:
This paper uses several large cross-sectional data sources and a new approach to estimate midlife effects of entering the labor market in a recession on mortality by cause and various measures of socioeconomic status. We find that cohorts coming of age during the deep recession of the early 1980s suffer increases in mortality that appear in their late 30s and further strengthen through age 50. We show these mortality impacts are driven by disease-related causes such as heart disease, lung cancer, and liver disease, as well as drug overdoses. At the same time, unlucky middle-aged labor market entrants earn less and work more while receiving less welfare support. They are also less likely to be married, more likely to be divorced, and experience higher rates of childlessness. Our findings demonstrate that temporary disadvantages in the labor market during young adulthood can have substantial impacts on life time outcomes, can affect life and death in middle age, and go beyond the transitory initial career effects typically studied
Speaker Bio:
Hannes Schwandt’s research agenda lies at the intersection of health economics, labor economics, and economic demography and focuses on the role of physical and mental health in determining economic inequality. Core research questions include how economic crises impact health and human capital trajectories; and how (non-COVID-19) infectious disease impair population health and disrupt economic productivity. Hannes' research has been published in general interest journals, such as Science and PNAS, and it is frequently covered by leading media outlets, such as New York Times, Washington Post, the Economist, and NPR. At Northwester, Hannes is teaching a new course on "The Economics of Health, Human Capital, and Happiness." Hannes received his PhD in Economics at Universitat Pompeu Fabra in Barcelona and help positions at Princeton and University of Zurich as a post-doc and assistant professor, respectively, before joining Northwestern in 2018.

TALK TITLE:
Human and Machine Perception of Voice Similarity
ABSTRACT:
Modern voice cloning systems generate synthetic speech that listeners frequently cannot identify as being synthetic. But a voice can sound natural without sounding like the intended person, and what determines whether a clone is heard as a particular person is an open question. Here we report a large-scale preregistered experiment in which we collected 92,239 responses from 175 participants on their perception of pairs of real recordings, voice clones, and continuously morphed voices drawn from 100 contemporary celebrities across 20 speaker groups. We find that voice clones do not reliably preserve perceived speaker identity, reducing same-speaker judgments by 12.7 percentage points even though the clones are produced by a state-of-the-art text-to-speech model, while leaving different-speaker judgments unchanged. Using continuously morphed stimuli, we find that speakers vary substantially in how much variation their perceived identity tolerates, and that this variation is not predicted by speaker demographics. Speaker embeddings account for 58.9\% (95\% CI = [55.7, 61.9]) of variance in identity judgments, which is more than acoustic features, social attributes, and clone status combined. Once all these observed features are accounted for, clone status adds no additional predictive power. These results shows that the perceptual impact of voice cloning is positional rather than categorical: we can model how listeners judge a voice by how close it falls to the perceptual boundary that defines each speaker's recognizable voice, applying the same criterion to real and synthetic speech alike.
DATA SCIENCE NIGHTS are monthly meetings featuring presentations and discussions about data-driven science and complex systems, organized by Northwestern University graduate students and scholars. Students and researchers of all levels are welcome! For more information: http://bit.ly/nico-dsn
