What makes Individual I's a Collective We; Coordination mechanisms & costs
Jisung Yoon, Chris Kempes, Vicky Chuqiao Yang +3
The collective effort exceeds the sum of its parts when individuals coordinate and regulate their activities and behaviors. This holds true even in self-organizing systems with ope…
Skill dependencies uncover nested human capital
Moh Hosseinioun, Frank Neffke, Letian Zhang +1
Modern economies require increasingly diverse and specialized skills, many of which depend on the acquisition of other skills first. Here we analyse US survey data to reveal a nest…
Scaling Laws for Function Diversity and Specialization Across Socioeconomic and Biological Complex Systems
Vicky Chuqiao Yang, James Holehouse, Hyejin Youn +4
Function diversity, the range of tasks individuals perform, and specialization, the distribution of function abundances, are fundamental to complex adaptive systems. In the absence…
Metrics and Mechanisms: Measuring the Unmeasurable in the Science of Science
Lingfei Wu, Aniket Kittur, Hyejin Youn +4
What science does, what science could do, and how to make science work? If we want to know the answers to these questions, we need to be able to uncover the mechanisms of science,…
A common trajectory recapitulated by urban economies
Inho Hong, Morgan R. Frank, Iyad Rahwan +2
Is there a general economic pathway recapitulated by individual cities over and over? Identifying such evolution structure, if any, would inform models for the assessment, maintena…
Morphology of travel routes and the organization of cities
Minjin Lee, Hugo Barbosa, Hyejin Youn +2
The city is a complex system that evolves through its inherent social and economic interactions. Mediating the movements of people and resources, urban street networks offer a spat…
The ecological and evolutionary energetics of hunter-gatherer residential mobility
Marcus J. Hamilton, Jose Lobo, Eric Rupley +2
Residential mobility is deeply entangled with all aspects of hunter-gatherer life ways, and is therefore an issue of central importance in hunter-gatherer studies. Hunter-gatherers…
Technological novelty profile and invention's future impact
Daniel Kim, Daniel Burkhardt Cerigo, Hawoong Jeong +1
We consider inventions as novel combinations of existing technological capabilities. Patent data allow us to explicitly identify such combinatorial processes in invention activitie…
On the universal structure of human lexical semantics
Hyejin Youn, Logan Sutton, Eric Smith +5
How universal is human conceptual structure? The way concepts are organized in the human brain may reflect distinct features of cultural, historical, and environmental background i…
Invention as a Combinatorial Process: Evidence from U.S. Patents
Hyejin Youn, Luis M. A. Bettencourt, Deborah Strumsky +1
Invention has been commonly conceptualized as a search over a space of combinatorial possibilities. Despite the existence of a rich literature, spanning a variety of disciplines, e…
The systematic structure and predictability of urban business diversity
Hyejin Youn, Luís M. A. Bettencourt, José Lobo +3
Understanding cities is central to addressing major global challenges from climate and health to economic resilience. Although increasingly perceived as fundamental socio-economic…
The hypothesis of urban scaling: formalization, implications and challenges
Luis M. A. Bettencourt, Jose Lobo, Hyejin Youn
There is strong expectation that cities, across time, culture and level of development, share much in common in terms of their form and function. Recently, attempts to formalize ma…
Constructing cities, deconstructing scaling laws
Elsa Arcaute, Erez Hatna, Peter Ferguson +3
Cities can be characterised and modelled through different urban measures. Consistency within these observables is crucial in order to advance towards a science of cities. Bettenco…
Professional diversity and the productivity of cities
Luís M. A. Bettencourt, Horacio Samaniego, HyeJin Youn
The relationships between diversity, productivity and scale determine much of the structure and robustness of complex biological and social systems. While arguments for the link be…
The Price of Anarchy in Transportation Networks: Efficiency and Optimality Control
Hyejin Youn, Michael T. Gastner, Hawoong Jeong
Uncoordinated individuals in human society pursuing their personally optimal strategies do not always achieve the social optimum, the most beneficial state to the society as a whol…
