This paper provides a theoretical framework to study the relationship between expanded road capacity, traffic volumes and increased economic activity. We build on Anas (2024) to show that increased traffic volumes do not necessarily lead to congestion if adjustments in econòmic factors, such as population or employment, are not substantial. We test our predictions obtaining key estimates with data from Great Britain between 2001 and 2020, and adopting a shift-share instrumental variable approach. We find that the elasticity of vehicle kilometers traveled to road capacity improvements is positive and statistically different from 1 across different specifications, while the elasticity of population and employment is positive but smaller than 1. In our framework this implies that the cost of driving does not increase above initial levels, resulting in higher consumer surplus through changes in travel demand and time savings.

This paper examines the lasting impact of tourism specialization on per capita income in Spanish municipalities, aiming to understand the factors driving these effects. We employ two distinct approaches. The first one focuses on tourism development since the initial boom in the 1960s and relies on cross-sectional variation in tourism exposure related to amenities like beaches and weather for identification. The second method looks at a later wave of tourism development in the 1990s, using a shift-share analysis that combines the share of residents from tourist-source countries in each municipality with the growth rate of tourists from these countries throughout Spain. The findings indicate that municipalities with the highest growth in tourism specialization now exhibit lower per capita income. A municipality experiencing an increase in tourism per capita over time equal to the sample median has a per capita income between 21% and 22% lower as of 2019, depending on the approach used. This decline in income is associated with an increase in temporary job contracts, with a decrease in industrial employment, and with lower levels of educational attainment.

We study the impact of improved rail access on entrepreneurship rates in England and Wales. We use data from the Census spanning 2001, 2011, and 2021 to analyse self-employment rates in granular geographic areas of around 200 residents. Specifically, we study how they respond to changes in the distance to the nearest train station occurring due to 56 new station openings. We find that all else equal, moving 1 km further away from a station reduces self-employment rates by 0.12 percentage points, with the effect dissipating beyond 7 km. Secondary results suggest that access to rail makes it easier to become self-employed while not making it more attractive compared to employment. Our findings suggest that rail infrastructure improvements can support local entrepreneurship and economic activity, contributing to regional development and reducing economic inequality.

Coastal development has advantages, such as job creation, and drawbacks, such as the loss of environmental amenities, for both residents and nonresidents. Local governments may prioritize their constituents’ interests, resulting in suboptimal coastal development. We investigate how political alignment among neighboring mayors facilitates intergovernmental cooperation in the development of coastal areas. We leverage causal effects by applying a close-elections Regression Discontinuity Design to the universe of buildings in Spain. Municipalities with party-aligned mayors develop 46% less land than politically isolated ones, and politically homogeneous coastal areas develop less than fragmented ones. The effect is more salient for land closest to shore or previously occupied by forests, in municipalities with a large share of protected land, and for relevant environmental markers, such as air and bathing water pollution. These results underscore the importance of cooperative political endeavors in managing development spillovers, with environmental considerations assuming a central role.
