The Reverse Side of Online Shopping: Examining Sociodemographic and Built-Environment Determinants of Delivery Returns

The rapid growth of e-commerce has created new transportation challenges through increased product returns, yet the behavioral determinants of delivery return patterns remain understudied from a consumer-centric perspective. This research develops a comprehensive econometric framework to analyze online shopping frequency, delivery return rates, and return channel preferences using data from the 2022 National Household Travel Survey (NHTS). We employ a multivariate modeling approach integrating probit ordered-response and probit fractional response models to examine three interconnected outcomes: (1) frequency of online goods purchases, (2) proportion of online purchases returned, and (3) distribution of returns across four channels (home pickup, post office, Amazon drop-off, and physical store). The results reveal significant sociodemographic heterogeneity in online purchasing and return behavior. Built environment factors also significantly influence return behaviors. The findings have important implications for transportation planning and urban logistics, highlighting the need for policies that ensure equitable return access and the importance of integrating e-commerce return trips into travel demand models.

Keywords: E-commerce returns, online shopping behavior, transportation planning, reverse logistics, consumer behavior.

Each year, Northwestern University's Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA) invites a renowned speaker to campus for our Annual Public Lecture. This year's speaker is Harvard astronomer and experimental physicist Professor Christopher W. Stubbs.

This year marks the birth of an ambitious new scientific project. Based in Chile, the Vera C. Rubin Observatory will take a decade-long time-lapse movie of the entire Southern sky, using the largest digital camera ever made. First-look images were released this summer, and the project is now transitioning into full operation.

Professor Stubbs' talk will describe how the unprecedented torrent of 20 terabytes per night will propel projects ranging from searches for potentially hazardous asteroids to mapping out the history of cosmic expansion. In particular, the Rubin data will provide new insights into "dark matter," the mysterious substance that comprises 90% of the mass in our own Milky Way galaxy, as well as "dark energy," which is driving the runaway expansion of the Universe. Stubbs will also describe the evolution of the project itself, and the romance of working in the high Atacama desert.

This event is generously supported by The Alumnae of Northwestern University.

The Chemical and Biological Engineering Department is pleased to present the 19th Annual Richard S.H. Mah Lectures on Modeling and Computation in Chemical and Biological Engineering with David Sholl from The University of Tennessee Oak Ridge National Laboratory.

How Reliable is the Chemical Engineering and Materials Chemistry Literature?

Reliability and reproducibility are bedrock principles of quantitative research in engineering and the physical sciences. Systematic efforts testing reproducibility of findings from the peer-reviewed literature in fields including biomedicine and psychology have given striking examples with high failure rates. How relevant are these observations to the chemical engineering and materials chemistry literature? This question has always been important for researchers basing their work on earlier reports, but has even more resonance when considering AI methods that are trained on large collections of published data. I will describe systematic efforts to assess reproducibility in studies of porous adsorbents, and argue that the characteristics of this specific topic are relevant to many areas in chemical engineering and materials chemistry. I will also describe approaches available to individual researchers, reviewers, and journals to improve reproducibility.

David Sholl is the Executive Director and Vice Provost of the University of Tennessee Oak Ridge Innovation Institute (UT-ORII), Director of the Transformational Decarbonization Initiative at the Oak Ridge National Laboratory, and the Editor-in-Chief of AIChE Journal.
