Concerns about crime and safety have a dramatic impact on the behavior of Airbnb customers, according to new research co-authored by Liad Wagman, Ph.D., Dean of the RPI Lally School of Management.
In an analysis of nearly 5 million reviews left by Airbnb guests, Wagman and his colleagues found that a short-term rental property’s occupancy rate and rental price dropped by significant amounts after a guest left a review mentioning safety concerns at or around the property: occupancy rates fell by anywhere from 1.5 to 2.4 percent, while average nightly prices dropped by roughly 1.5 percent.
These negative safety reviews influenced the behavior not only of potential future customers, but also of the people who wrote them. A customer who mentioned concerns about crime and safety in the neighborhood around a property, for instance, became 60 percent less likely to ever use Airbnb again.
“To see the effect of these dynamics play out in action is always fascinating to me," Wagman said. “Given that humans have different preferences, and that information transmittal is imperfect, it’s unsurprising that the effect of self-experience is larger than that of reading a critical review that resulted from it.” Worries about safety within a property — say, a broken step or a slippery tub — also reduced customers’ willingness to return to the platform, but by a more modest amount.
The study also found that when people with neighborhood safety concerns did return to the platform, they tended to book properties in areas with lower rates of crime.
The study, co-authored by Aron Culotta of Tulane, Ginger Zhe Jin of the University of Maryland, and Yidan Sun of Binghamton University, was published in the journal Marketing Science.
Overall, the researchers found that safety-oriented reviews were rare: only about 0.5 percent of customer reviews mentioned safety concerns. But those reviews tend to be more negative in sentiment than the typical customer review, giving them an outsize impact on the behavior of subsequent would-be customers.
The findings illustrate a delicate balancing act digital platforms have to perform, particularly those that rely heavily on user reviews: while highlighting negative experiences can help consumers make more informed choices, too much emphasis can drive customers away completely.
The team ran several simulations calibrated by their empirical analysis to test how these dynamics play out in the market. They found that if a platform suppressed negative safety reviews completely, customers might assume that safety information was being hidden, and become more wary of using the platform in general.
Conversely, while more transparency around safety issues could lead to fewer bookings of impacted properties in the short term, in the long run such a policy could boost user trust and draw more people to the platform, offsetting the short-term losses.
“Platforms with the competitive space to focus on long-term objectives may benefit from a higher level of transparency, which can be facilitated by making information that is relevant to their buyers’ decision-making more readily available,” Wagman said. “Doing so facilitates trust and helps incentivize sellers to work to improve the quality of their offerings, as well as help shape sellers' decisions to enter a market (e.g., offer their listings) in the first place.”
As nations and private companies prepare to ramp up the number of missions to the Moon, researchers at Rensselaer Polytechnic Institute (RPI) and Texas A&M University have secured a $1 million grant from the Air Force Office of Scientific Research to develop a system to track and monitor resident space objects — including spacecraft, satellites and debris — moving through the vast cislunar space between the Earth and the Moon.
The initiative, called RCAT-CS (Reconfigurable Constellations for Adaptive Tracking in Cislunar Space), will develop intelligent networks of sensor satellites that can be reconfigured to perform resilient tracking of objects as they maneuver through this complex orbital environment.
"Right now, we're seeing an explosive growth in cislunar missions, including everything from commercial lunar landers and orbiters to next-generation spacecraft that secure national interests in this contested domain," said engineering professor Sandeep Singh, Ph.D., RPI’s lead investigator on the project. "But our ability to track what's happening out there hasn't kept pace. Ground-based sensor systems have blind spots and cannot reliably provide measurements. A space-based constellation is the answer, but placing spacecraft in orbit is expensive and solving the resource constraint problem is essential." The cislunar region presents unique challenges for space domain awareness applications. Competing gravitational forces from the Earth and the Moon create complex orbital dynamics, while the sheer distances involved make tracking difficult. When spacecraft and satellites perform maneuvers in this space or behave unexpectedly, current systems can lose track of them entirely.
RCAT-CS will tackle these problems by designing constellations of space-based sensors that can dynamically reposition themselves based on what they're observing. Professor Singh and his colleagues will develop novel algorithms to detect maneuvers made by tracked objects, balance fuel costs, track performance of the sensing satellites, and quantify the uncertainties underlying it all.
The system addresses critical safety and security needs as cislunar space becomes increasingly congested and contested. The research will also advance fundamental knowledge in orbital dynamics and autonomous space systems, with implications for mission planning, collision avoidance, and safe coordination of a growing cislunar economy. Additionally, the project will train the next generation of space engineers in cutting-edge technologies essential for American leadership in space operations.
“Congratulations to Professor Sandeep Singh and his team on securing a research grant in the important area of lunar space exploration,” said Shekhar Garde, Ph.D., the Thomas R. Farino Jr. ’67 and Patricia E. Farino Dean of the School of Engineering. “RPI has always been at the frontier of space exploration, from George Low’s work on the Apollo program to the forthcoming Artemis II mission, led by Commander Reid Wiseman ’97.” “Professor Singh’s work will not only advance research, it will strengthen RPI’s recently launched Aerospace Engineering undergraduate program by bringing the latest research into our classrooms,” Garde added.

Rensselaer Polytechnic Institute (RPI) officially cut the ribbon on its new Center for Smart Convergent Manufacturing Systems (CSCMS) during an all-day launch event on October 23, 2025. A New York State Center for Advanced Technology, CSCMS will redefine the very nature of manufacturing by combining robotics, artificial intelligence, advanced processing, and human ingenuity to create systems that think, adapt, and evolve alongside human operators.
“Today we mark the official opening of a center with a bold vision: a future where manufacturing systems are not simply automated, but truly intelligent,” said RPI President Martin A. Schmidt ’81 during the ribbon cutting. CSCMS will bring a wealth of opportunities not only to RPI, but across New York State. The new center will serve as a catalyst for economic growth, empowering innovators, driving new technologies, and strengthening the competitiveness of manufacturers. At RPI, students will gain hands-on experience in labs, real-world projects, and entrepreneurial pathways. Faculty and industry partners will gain the resources to translate cutting-edge research into commercial solutions.
“Through simulation, prototyping, and translational research, our faculty and students will work side by side with industry and government to accelerate the development and deployment of smart manufacturing solutions,” said President Schmidt. “This is the RPI model at its very best: turning ideas into impact.” The launch event for CSCMS took place on RPI’s campus and featured keynote remarks, a ribbon cutting, industry panel, poster sessions, lab tours, and demonstrations of robotic manufacturing, human-machine collaboration, smart manufacturing testbeds, intelligent production systems, and data visualization spaces. Industry panel speakers included executives from FuzeHub, Ross Precision Manufacturing, GE Aerospace Research, and The Boeing Company. Interactive student poster sessions covered topics such as robotics, AI, advanced manufacturing, and New York’s future at the convergence of these topics.
“The launch of CSCMS comes at a pivotal time for manufacturing,” said Johnson Samuel, Ph.D., director of CSCMS. “Across industries, we are seeing the convergence of AI, robotics, and data-driven design transforming how products are made. RPI’s long-standing strengths in engineering, computing, and innovation make it the perfect home for this next-generation center.” “The energy and collaboration we saw during this event are a reflection of the momentum behind the entire CSCMS initiative,” said Sandipan Mishra, Ph.D., associate director of CSCMS. “This launch is the start of a sustained effort to shape the future of intelligent manufacturing in New York and beyond.” "It's exciting that as students, we get to work with these cutting-edge technologies up close and be a part of something that’s pushing manufacturing forward,” said RPI graduate student Ammar Barbee ‘25, who recently completed his bachelor’s degree in mechanical engineering at RPI. “Perusing this kind of research and having access to such advanced equipment enables unique experiences that will really help accelerate our careers.” With the launch of CSCMS, RPI continues to advance its legacy of innovation and partnership, bringing together academia, industry, and government to drive progress in intelligent manufacturing and strengthen New York’s position as a hub for technological excellence.
