Title: The goods-leisure model in the bottleneck: when time is not only money


Martina Gregori will give a talk about her recent research on the so-called "bottleneck model", formalised by Vickery (1969) and elaborated by Arnott, de Palma and Lindsey (1990, 1993). This model is among the most used approaches in studying phenomena related to congestion. Decades after its formalisation, the classic bottleneck model is still broadly applied in relevant transport economics research works, published in top-field scientific journals.

The seminar will focus on her research work in understanding the origin of the scheduling preferences assumptions – over being early/late and spending time queueing – that base the basic bottleneck model and can naturally be observed in the individuals' daily behaviour.

First, she will present the classical bottleneck model formulation and assumption. In particular, she will present the most relevant intuitions derived from the formulation, which directly affect the regulation of congestion phenomena.

Secondarily, she will present an alternative formulation for the bottleneck model. Starting from the intuition that time is not only money, it is demonstrated that it is possible to justify tendencies towards travel preferences endogenously by letting individuals have free choice over how to allocate their free time. Moreover, given a set of parameters, the proposed alternative formalisation endogenously determined which types of equilibrium describe the congestion evolution best, depending on users' characteristics. Overall, the obtained results propose an alternative micro foundation for the classical bottleneck model.


Martina Gregori, is Post-Doc at Sapienza University of Rome, where she obtained a Ph.D. in Industrial and Management Engineering in 2021. She visited Universidad de Chile (Santiago de Chile, Chile) in 2019 as a Ph.D. student.  

She works in the areas of transport economics, industrial organisation and performance evaluation. She is also interested in higher education systems analysis, especially concerning heterogeneity among institutions (micro) and national systems (macro).

She teaches Economics of Technology and Management and the Laboratory of Industrial and Management Engineering.
