How bad is selfish routing in practice? [article]

Barnabé Monnot, Francisco Benita, Georgios Piliouras
2017 arXiv   pre-print
Routing games are one of the most successful domains of application of game theory. It is well understood that simple dynamics converge to equilibria, whose performance is nearly optimal regardless of the size of the network or the number of agents. These strong theoretical assertions prompt a natural question: How well do these pen-and-paper calculations agree with the reality of everyday traffic routing? We focus on a semantically rich dataset from Singapore's National Science Experiment that

Using this dataset, we can identify the routes as well as the modes of transportation used by the students, e.g. car (driving or being driven to school) versus bus or metro, estimate source and sink destinations (home-school) and trip duration, as well as their mode-dependent available routes. We quantify both the system and individual optimality. Our estimate of the Empirical Price of Anarchy lies between 1.11 and 1.22. Individually, the typical behavior is consistent from day to day and nearly optimal, with low regret for not deviating to alternative paths.

On the competitiveness of Mexico's dry chili production

David Gaytán, Francisco Benita
2014 Ekonomika Poljoprivrede (1979)  
Mexico has become the sixth-largest dry chili exporter in the world and the largest chili (Capsicum annuum L) exporter, showing not only its production capacity but also giving it a decisive advantage over its main competitors. The aim of this paper is to describe the competitive structure and dynamics of chili exportations in Mexico over the period [1993][1994][1995][1996][1997][1998][1999][2000][2001][2002][2003][2004][2005][2006][2007][2008]. In order to compare the export growth performance

For all countries included in the analysis, the study considers the U.S as the objective market due to the current dry chili export market participation. The result suggests that Mexico occupies an important place in the global production but not a leadership place in exportations of dry chili at worldwide level.

A Cohort Analysis of the College Premium in Mexico

Francisco Benita
2014 Latin american journal of economics  
This paper provides the first empirical evidence for Mexico about relative wage dif ferences between college-educated and high-school-educated workers across five-year age groups. Rotating panel surveys are used to implement an imperfect substitution model for similar male workers between dif ferent age groups and between the two education groups. For the period 2005-2012, the results suggest a partial elasticity of substitution of 1.7 for college-and high-school-educated workers and a partial

Data-Driven Models of Selfish Routing: Why Price of Anarchy Does Depend on Network Topology [article]

Francisco Benita, Vittorio Bilò, Barnabé Monnot, Georgios Piliouras, Cosimo Vinci
2022 arXiv   pre-print
We investigate traffic routing both from the perspective of theory as well as real world data. First, we introduce a new type of games: θ-free flow games. Here, commuters only consider, in their strategy sets, paths whose free-flow costs (informally their lengths) are within a small multiplicative (1+θ) constant of the optimal free-flow cost path connecting their source and destination, where θ≥0. We provide an exhaustive analysis of tight bounds on PoA(θ) for arbitrary classes of cost
more » ... , both in the case of general congestion/routing games as well as in the special case of path-disjoint networks. Second, by using a large mobility dataset in Singapore, we inspect minute-by-minute decision-making of thousands of commuters, and find that θ=1 is a good estimate of agents' route (pre)selection mechanism. In contrast, in Pigou networks, the ratio of the free-flow costs of the routes, and thus θ, is infinite; so, although such worst case networks are mathematically simple, they correspond to artificial routing scenarios with little resemblance to real world conditions, opening the possibility of proving much stronger Price of Anarchy guarantees by explicitly studying their dependency on θ. For example, in the case of the standard Bureau of Public Roads (BPR) cost model, wherec_e(x)= a_e x^4+b_e, and for quartic cost functions in general, the standard PoA bound for θ=∞ is 2.1505, and this is tight both for general networks as well as path-disjoint and even parallel-edge networks. In comparison, for θ=1, the PoA in the case of general networks is only 1.6994, whereas for path-disjoint/parallel-edge networks is even smaller (1.3652), showing that both the route geometries as captured by the parameter θ as well as the network topology have significant effects on PoA.
