(Press-News.org) A new paper in the Quarterly Journal of Economics, published by Oxford University Press, shows customer service workers using artificial intelligence assistance become more productive and work faster. The effects vary significantly, however. Less experienced and lower-skilled employees improve both the speed and quality of their work, while the most experienced and highest-skilled workers see small gains in speed and small declines in quality. The researchers also found that AI assistance can help worker learning and improve English fluency, particularly for international workers.
Computers and software have transformed the economy with their ability to perform certain tasks with far more precision, speed, and consistency than humans. Yet, despite significant advances in traditional computing, some workplace activities—writing emails, analyzing data, or creating presentations—are difficult to codify and have defied computerization.
Computers historically did well with pre-programmed instructions, making them effective for tasks with explicit rules. Computerization has therefore disproportionately decreased the demand for workers performing routine and repetitive tasks such as data entry, bookkeeping, and assembly line work, reducing wages in these jobs. But computerization has increased the demand for workers who possess complementary skills such as programming, data analysis, and research. As a result, technology-related shifts in the labor market have contributed to increased wage inequality.
Researchers here studied the impact of generative AI on productivity and workers’ experience in the customer service sector by examining the use of a new chat assistant by 5,172 customer support agents. The agents worked at a Fortune 500 firm that sells business process software.
The investigation had several findings. First, AI assistance increased worker productivity, resulting in a 15 percent increase in the number of chats that an agent successfully resolved per hour.
Second, the impact of AI assistance varies widely. Less-skilled and less-experienced workers improve significantly across all productivity measures, including a 30 percent increase in the number of issues resolved per hour. The AI tool also helps newer agents become skilled agents more quickly AI-assisted agents with two months of tenure performed just as well as regular agents with more than six months of tenure. In contrast, AI has little impact on the productivity of higher-skilled or more experienced workers. Indeed, the investigation here showed that AI assistance leads to a small decrease in the quality of conversations conducted by the most skilled agents.
Third, agents who follow AI recommendations closely generally see larger gains in productivity, and adherence rates increase over time. The investigators here also analyzed the text of agents’ chats and showed that access to AI improves their English language fluency, especially among international agents.
Finally, using AI appears to improve customer behavior. Contact center work is challenging, and employees face hostile interactions from anonymous, frustrated customers frequently. The researchers here show that access to AI assistance significantly improves the treatment of agents, as reflected in the tone of customer messages. Customers are also less likely to question agents’ competence or ask to speak to a supervisor.

International collaborative research led by Aakash Project* researchers at the Research Institute for Humanity and Nature (RIHN) show an unequivocal contribution of crop residue burning (CRB) to air pollution in the rural/semi-urban regions of Punjab and Haryana, and a relatively lower contribution than previously thought to the Delhi national capital region (NCR). We have installed 30 units of compact and useful PM2.5** in situ instrument with gas sensors (CUPI-Gs) and have continuously recorded air pollutants in 2022 and 2023. New analytical methods have been developed to assess ...
Discovery of water droplet freezing steps bridges atmospheric science, climate solutions
2025-02-04
A groundbreaking University of Hawaiʻi at Mānoa study on the freezing of water droplets suspended in air sheds light on a key process in Earth’s water cycle: the transformation of supercooled water into ice.
Conducted using a novel cryogenically cooled ultrasonic levitation chamber, the research captures real-time molecular-level changes during the freezing process, mimicking conditions in the Earth’s atmosphere. This innovative setup enables researchers to observe how water droplets transition to ice at subzero temperatures, providing ...
Positive emotions plus deep sleep equals longer-lasting perceptual memories
2025-02-04
Researchers at the RIKEN Center for Brain Science (CBS) have uncovered how perceptual memories linked to positive emotions, such as joy or happiness, are strengthened during sleep. The study, published in the scientific journal Neuron, could help scientists understand the neurological basis for overcoming conditions like drug or sexual addiction.
Why do emotional events, whether positive or negative, create strong, long-lasting memories of external information such as music, scene smells and textures received at the events? We know that sleep is essential for memory consolidation, the process that turns new events into memories, but do not ...

Study examines how African farmers are adapting to mountain climate change
2025-02-03
A new international study highlights the severity of climate change impacts across African mountains, how farmers are adapting, and the barriers they face – findings relevant to people living in mountain regions around the world.
"Mountains are the sentinels of climate change,” said Julia Klein, a Colorado State University professor of ecosystem science and sustainability and co-author of the study. “Like the Arctic, some of the first extreme changes we're seeing are happening in mountains, from glaciers melting to extreme events. There's greater warming at higher elevations, so what's happening in mountains is foreshadowing what's going ...
Exposure to air pollution associated with more hospital admissions for lower respiratory infections
2025-02-03
Air pollution is a well-known risk factor for respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). However, its contribution to lower respiratory infections —those that affect the lower respiratory tract, including the lungs, bronchi and alveoli— is less well documented, especially in adults. To fill this gap in knowledge, a team from the Barcelona Institute for Global Health (ISGlobal), a centre supported by the ”la Caixa” Foundation, assessed the effect of air pollution ...
