Endogenous Region Formation
I apply spatial attributes to the Endogenous Firm Formation model by Axtell (2016) to grow regions. Migration occurs as workers switch between firms located in different regions. Overall, regional growth and decline depend on the performance of the firms located in them. |

Computational Social Science at Several Levels
Friday, December 8, 3:00 p.m.
Center for Social Complexity Suite
3rd Floor, Research Hall
ABSTRACT: Computational social science can enable understanding – and design – of a wide variety of phenomena at an enormous range of levels. This lecture will address processes, organizations, ecosystems, and society for phenomena associated with disease and medicine, health and well being, and technology adoption, particularly in automobiles. The process level is addressed in terms of scaling and optimization of medical innovations. The level of organizations is considered in the context of health provider corporations’ responses to the Affordable Care Act. The ecosystem level is discussed in addressing population health – integrated delivery of health, education, and social services – in the highly fragmented US ecosystem. The society level is considered in terms of the expected disruptive impacts of driverless cars on automotive, insurance, and finance industries. Approaches to and challenges of modeling at these differing levels are discussed.

Urban Development Through the Lens of Agent-Based Modeling
Friday, December 15, 3:00 p.m.
Center for Social Complexity Suite
3rd Floor, Research Hall
Abstract: Cities are ever changing and growing phenomenon with many underlying complexities. Through its life cycle, a city experiences various forms of dynamics. Models allow for a better understanding of such complexities and dynamics. The model presented in this talk simulates the dynamics of certain processes such as: an urban market, agent interactions in that market, urban growth, sprawl and shrinkage and gentrification. The purpose of this model is to understand the behavioral pattern of the agents and demonstrate the life cycle of a city based on individual agents’ actions. This model is significant in its integration of various subsystems creating a larger system while observing developers’ behavior. Specifically, the model explores some well-known issues, including the Smith’s rent-gap theory, Burgess’s concentric zones model of urban growth, and Alonso’s bid rent theory. The main results from the model show that the agents move to and reside in properties within their income range, with similar neighbors. This is one of the first models that provides a new lens to explore urban development.

Leveling the Playing Field: Information Asymmetry in the Used Vehicle Buying Process
Monday, January 29, 4:30-5:45
Exploratory Hall, Room 3301
Abstract
In 1970, Economist and Nobel Prize winner (2001) George Akerlof published a study: “The Market for “Lemons”: Quality Uncertainty and the Market Mechanism” (The Quarterly Journal of Economics, Vol. 84, No. 3. (Aug., 1970), pp. 488-500). In the study, Akerlof attempts to show where, in a market where as seller of a product has more data/information than the buyer of the product, about the product’s quality, will potentially result in “an adverse selection of low-quality products.” In no place is Akerlof’s theory more represented than in the used vehicle market, where buyers and sellers don’t always have the same information about a vehicle’s quality, potentially resulting in low-quality cars being bought and sold. In 1986, CARFAX sought to begin to “level the playing field” between buyers and sellers of used vehicles by collecting, analyzing and making relevant data/information available in the marketplace to both buyers and sellers.
- What data does CARFAX collect?
- Why this data vs other data?
- How does the market drive the type of data collected?
- How does CARFAX analyze and make this data available to answer real world questions?
-
Is this car safe?
-
How much should I pay for it?
-
What’s it worth?
-
What’s the risk to insure it?
-
What’s the risk to finance it?

ABSTRACT: Long ago Hunter Mill Road in Reston, Virginia, was surrounded by farmland and little travelled. Where it crosses Colvin Run creek a single-lane bridge was adequate for the traffic at the time. However, as the region grew in the post-WWII era the traffic on Hunter Mill Road increased until the single-lane bridge is today a bottleneck for rush-hour traffic, southbound toward the Dulles Toll Road in the morning and northbound in the evening. There are no stop signs on either side of the bridge but warning signs that the bridge is too narrow to handle two vehicles moving in opposite directions at the same time. During periods of low traffic—queue length 0 or 1—the usual first-come-first-served (FCFS) driver discipline is observed at the bridge, by which the first vehicle to approach from either side has the right-of-way. However, during periods of heavy traffic, such as the morning and evening ‘rush hours’, a different behavioral regime is observed: pairs of cars moving in the same direction cross the bridge together, in single file. This departure from the FCFS protocol clearly permits higher vehicular flowrates over the bridge in each direction. However, from the layout of the bridge and vehicular dynamic we demonstrate that the globally optimal behavior for the system during busy times would involve larger numbers of vehicles moving together across the bridge, i.e., groups of 3, 4, or even 5 produce shorter wait times overall, dominating the 2-car norm. We argue that this is an example of a sub- optimal spontaneous order, and go on to suggest that there is little reason to believe that (m)any spontaneous orders operate at anything like peak performance. Essentially, spontaneous orders in this context represent behavioral norms for multi-agent coordination problems that improve on so-called anarchic solutions identified with Nash equilibria of the underlying non-cooperative game. The welfare improvements associated with following the emergent social conventions represent a kind of satisficing solution of the type identified by Herbert Simon as a good description of human behavior in a wide variety of social situations, bounded by cognitive constraints, limited information, and incentive problems. We conclude by arguing that F.A. Hayek implicitly associated his conception of spontaneous order with high welfare, but that this view is untenable. Rather, the more general idea of emergence, which makes no welfare assertions, seems to subsume spontaneous order as a very special case, suggesting that Hayek’s contribution to this area has been largely supplanted by more recent developments in the science of complex systems, as has been argued elsewhere.

Why an open mind on open data can transform our collective intelligence
Monday, February 5, 4:30-5:45
Exploratory Hall, Room 3301
Abstract: In 1822, the founding father James Madison said: “A popular government, without popular information, or the means of acquiring it, is but a prologue to a farce or a tragedy, or perhaps both”. Recent technological waves have evidently served Madison’s vision of government transparency. The latest advancements in Artificial Intelligence (AI), Data Science, and Machine Learning can make federal data openness a low hanging fruit. Moreover, the big data and open government initiatives (signed in 2012 and 2013) are major enablers for transforming government into a new era of intelligent and data-driven policy making. However, to be able to use data in reforming the political discussion, public federal data needs to devise the promised openness.
Besides benefiting government, Open Data benefits many other domains and applications of data science, such as healthcare, finance, and academia. For example, Open Data could lead to a general openness in science (i.e. Open Science), clearer experimental research, and begin reshaping the human knowledge in general. These topics and other facets will be discussed in this talk.

DRAFTING AGENT-BASED MODELING INTO BASKETBALL ANALYTICS
Friday, February 9 – 3:00 p.m.
Center for Social Complexity Suite
3rd Floor, Research Hall
ABSTRACT: Sports analytics (SA) has experienced a meteoritic rise in recent years, with the trend forecast to continue. Modor Intelligence reports that the market was valued at USD 83.56 million in 2015, and is forecast to grow to USD 447.23 million by 2020. at the market was valued at USD 83.56 million in 2015, and is forecast to grow to USD 447.23 million by 2020.
The growth of sports analytics has raised a rich variety of research topics pertaining to basketball, including: how at the macro level the distribution of scoring activity is a mixture of random walk processes and power-law behavior (Gabel & Redner, 2012), and, at the individual level, the question of whether players develop hot-hands and how the player and their teammates react to its possible existence. While the erroneous belief regarding hot-hands was first identified by Gilovich, Vallone & Tversky (1985) it has remained an active field of research (Bar-Eli, Avugos, & Raab, 2006).
Agent-based modeling (ABM) has great potential to assist and inform those engaged in sports analytics but to date it has not been utilized. The advantage of ABM is that it allows researchers to assess, in a silicon laboratory, the micro-level interactions that give rise to verifiable macro outcomes. This is achieved through heterogeneous agents adapting and making decisions based on their environment, including considering spatial, temporal factors and interactions with other agents.
To support the use of ABM in sports analytics, I will present a 3-dimensional model of a basketball game, where the fundamentals of play including player and court positions, a shot clock, and shooting performance are all included. Additionally, player behavior in deciding whether to shoot, pass or dribble is partially predicated on assessing the length of a player’s shooting streak (designed to test the hot-hand effect), and the consideration they give to any streak, plus their franchise status, a feature identified in Burns (2004). The probabilistic nature of the model allows for insights into the dynamics of scoring actions following a random walk. The model captures extensive data which was used to calibrate and validate it against comparable statistics from the National Basketball Association (NBA).

Abstract: Modernization of nearly all the technology that underlies the provision of rail and bus transit service over the past 30 years has resulted in a vast amount of data that until recently has been more or less neglected. Meanwhile, challenges that face rail and bus transit systems continue to mount, from maintaining a state of good repair to capturing and keeping riders in the age of Uber/Lyft and bike share. The key to providing safe, convenient, affordable, and reliable transit service into the next century lies in the hands of data scientists and policy analysts. This talk will review the different data-generating technologies and the types of data they create, followed by an exploration of the pressing issues faced by transit agencies and the questions begging for answers.
Bio: Michael currently serves as Strategic Planning Advisor at WMATA in the Office of Planning’s Applied Planning Intelligence unit, where he focuses on transforming data into information to help inform policy and planning decisions.
