A Mathematical Model for the Origin of Name Brands and Generics
Joseph D. Johnson, Adam M. Redlich, Daniel M. Abrams
Firms in the U.S. spend over 200 billion dollars each year advertising their products to consumers, around one percent of the country's gross domestic product. It is of great inter…
Why are U.S. Parties So Polarized? A "Satisficing" Dynamical Model
Vicky Chuqiao Yang, Daniel M. Abrams, Georgia Kernell +1
Since the 1960s, Democrats and Republicans in U.S. Congress have taken increasingly polarized positions, while the public's policy positions have remained centrist and moderate. We…
When Pull Turns to Shove: A Continuous-Time Model for Opinion Dynamics
David Sabin-Miller, Daniel M. Abrams
Accurate modeling of opinion dynamics has the potential to help us understand polarization and what makes effective political discourse possible or impossible. Here, we use physics…
Modeling the origin of urban output scaling laws
Vicky Chuqiao Yang, Andrew V. Papachristos, Daniel M. Abrams
Urban outputs often scale superlinearly with city population. A difficulty in understanding the mechanism of this phenomenon is that different outputs differ considerably in their…
The Statistical Mechanics of Human Weight Change
John C. Lang, Hans De Sterck, Daniel M. Abrams
In the context of the global obesity epidemic, it is important to know who becomes obese and why. However, the processes that determine the changing shape of Body Mass Index (BMI)…
Matchmaker, Matchmaker, Make Me a Match: Migration of Populations via Marriages in the Past
Sang Hoon Lee, Robyn Ffrancon, Daniel M. Abrams +2
The study of human mobility is both of fundamental importance and of great potential value. For example, it can be leveraged to facilitate efficient city planning and improve preve…
Symmetry breaking in optimal timing of traffic signals on an idealized two-way street
Mark J Panaggio, Bertrand J Ottino-Löffler, Peiguang Hu +1
Simple physical models based on fluid mechanics have long been used to understand the flow of vehicular traffic on freeways; analytically tractable models of flow on an urban grid,…
A mathematical model of social group competition with application to the growth of religious non-affiliation
Daniel M. Abrams, Haley A. Yaple, Richard J. Wiener
When groups compete for members, the resulting dynamics of human social activity may be understandable with simple mathematical models. Here, we apply techniques from dynamical sys…
