The role of population density for economic activity was neglected in most part of economic theory. This paper is a review and extension of the previous works of the author in this field. So far, densities did not become common economic variables in economic analysis, and two countries with...

Since initially steaming from von Thünen's work (1826), bid-rent approach has been rigorously applied to analyze land use configuration. Alonso (1964), Muth (1969), Beckman (1973), Solow (1973), and Fujita (1989) are among the scientists who greatly contributed to forward von Thünen's theory...

This paper addresses the trade-off between unfavourable air pollution levels and favourable weather conditions for selecting a date for the staging of an outdoor event. For an event date that has been fixed, it presents a personal preference-based data-driven decision framework for individual...

Computational notebooks offer researchers, practitioners, students, and educators the ability to interactively conduct analytics and disseminate reproducible workflows that weave together code, visuals, and narratives. This article explores the potential of computational notebooks in urban...

High-occupancy vehicle (HOV) lanes have been promoted to encourage carpools, reduce traffic congestion, and improve air quality. At the partial equilibrium level, commuting with three workers per automobile clearly reduces highway congestion, lowers carbon emissions, and saves energy compared to...

This study proposes an empirical analysis to assess the changes recorded by the urban gradient when population size suffers from an important and unexpected shock. To this end, we build an original pseudo-panel covering information for the city of Barcelona from 1902 to 2011. Despite the...

Sustainable use of natural resources becomes an important issue today not only due to global warming and pollution issues but also because of critical pressure on the Earth's regeneration possibility. We cannot use classical microeconomic approach here for two reasons: a) impossibility to create...

What is a feasible and efficient policy to regulate air pollution from vehicles? A Pigouvian tax is technologically infeasible. Most countries instead rely on exhaust standards that limit air pollution emissions per mile for new vehicles. We assess the effectiveness and efficiency of these...

With 68% of the world population projected to live in urban areas by 2050, mass transit networks are expanding faster than ever before. But how are the economic gains from such expansions being shared between low- and high-income workers? Existing research focuses on the role of commuting to...

When large numbers of people are enabled to travel rapidly around the country, will it affect information production in capital markets? We study a government-directed buildout of high-speed rails (HSR) and find that after being connected to the HSR network, firms experience increased...
