Publications

Thanks to my time as an academic, I have written quite a few (technical) publications. Peruse these below, or jump to my Google Scholar Page or arXiv papers

Tech Blogs

API Call Logging at Bond (June, 2022) Note: yes, I wrote this blog post and was the tech lead behind the work (direction, execution, and rollout). Not the currently listed author, who took over the byline when I left Bond.

Peer-Reviewed Journal Articles

“Forecasting light-duty vehicle demand using alternative-specific constants for endogeneity correction versus calibration.” (2016)  We examine econometric-style estimation of random coefficient Logit models, and associated forecasts, with “alternative specific constants” in both model calibration and estimation. With C. Grace Haaf, Jeremy J. Michalek, Ines Azevedo, Elea Feit and published in Transportation Research Part B 84, 182-210 (link)

“Finite Purchasing Power and Computations of Bertrand-Nash Equilibrium Prices.” (2015)  I describe numerical methods useful for computing Bertrand-Nash equilibrium prices when the purchasing population is modeled by a Mixed Logit model with finite purchasing power. Published in Computational Optimization and Applications 62(2) (link)

“Should Optimal Designers Worry About Consideration?” (2015) We study optimal product design strategy when the designer estimates a choice model based on market shares, uses that choice model in design optimization, and the population exhibits “consideration” behavior. With Minhua H. Long, and published in the Journal of Mechanical Design 137(7), 071411 1-9 Special issue on User Needs and Preferences in Engineering Design. (link)

“Sensitivity of Vehicle Market Share Predictions to Alternative Discrete Choice Model Specifications.” (2014) We examine “short” and “long” run forecast accuracy from Multinomial Logit models estimated with market share data, testing 9,000 or so models with different functional forms for systematic utility. With C. Grace Haaf, J.J. Michalek, Yimin Liu, and published in the Journal of Mechanical Design 136(12) pgs. 121402,1-9 (link) See also the supplemental information (link)

“Numerically Stable Design Optimization with Price Competition” (2014) We study numerical methods capable of reliably and efficiently solving optimal design problems when the modeler includes a game-theoretic equilibrium pricing stage. With Joshua Mineroff & Kate S. Whitefoot, and published in the Journal of Mechanical Design 136(8) pgs. 081002,1-17 (link)

“Market-System Design Optimization with Consider-then-Choose Models.” (2014) We study numerical methods capable of solving non-smooth optimal design problems generated by using choice models with consideration behavior, including proposed methods using complementarity constraints. With Minhua H. Long & Erin F. MacDonald and published in Journal of Mechanical Design 136(3) pgs. 031003,1-13 (link)

“Consequential Lifecycle Assessment with Market-Driven Design: Development and Discussion.” (2011) We study inclusion of system-level effects in an LCA methodology, particularly feedbacks derived from engineering design and market pricing. With Kate S. Whitefoot, Hillary Grimes-Casey, C. Girata, James J. Winebrake, Gregory A. Keolian, & Steven J. Skerlos and published in the Journal of Industrial Ecology. 15(5) pg. 726-742. (link)

“Fixed-Point Approaches to Computing Bertrand-Nash Equilibrium Prices Under Mixed Logit Demand” (2011) We study fixed-point methods useful for computing Bertrand-Nash equilibrium prices, and justify newly proposed methods using coercivity and fundamental convergence theory for nonlinear systems methods. This paper also contains an explicit example of a Bertrand-Nash equilibrium pricing problem with multiple equilibria. With Steven J. Skerlos, and published in Operations Research 59(2) pg. 328-345. (link) See also the corresponding arXiv report (arXiv)

“Analysis of Policies to Reduce Oil Consumption and Greenhouse Gas Emissions from the U.S. Transportation Sector”(2010) We study transportation-sector-specific climate policies under an economy-wide carbon price using the DOE’s National Energy Modeling System. With Kelly Sims-Gallagher, Gustavo Collantes, & Henry Lee and published in Energy Policy 38(3), 1305-1320 (link) Also published as a Discussion Paper (link)

“Environmental aspects of laser-based and conventional tool and die manufacturing.” (2007) We conduct an environmental assessment of laser-based metal deposition in manufacturing and re-manufacturing in tooling applications. With H. Qi, Inki Kim, Jyoti Mazumder, & Steven J. Skerlos and published in the Journal of Cleaner Production 15(10) pg 932-943 (link)
