This paper constructs a theoretical model that facilitates analysis of the effects of employer-paid parking on mode choice, road investment and suburbanization. The model simplifies urban space by dividing it into two zones (islands), center and suburbs, which are connected by a congested road...

In 2022, Germany introduced a temporary 9-euro monthly ticket for unlimited local and regional public transport. We investigate its impact on mobility patterns, including increased public transport usage, reduced car traffic, and rail network congestion. Using difference-in-difference and...

This paper studies drivers' responses to a "notched" penalty scheme in which speeding penalties are stepwise and discontinuously increasing in speed. We present survey evidence suggesting that drivers in Germany are well aware of the notched penalty structure. Based on a simple analytical...

Transport has significant externalities including carbon emissions and air pollution. Public health research has identified additional social gains from active travel, due to health benefits of physical exercise. Per mile, these benefits greatly exceed the external costs from car use. We...

An individual’s initial experiences with a common good, such as gasoline, can shape their behavior for decades. We first show that the 1979 oil crisis had a persistent negative effect on the likelihood that individuals that came of driving age during this time drove to work in the year 2000...

We study a model of social learning in networks where the dynamics of beliefs are driven by conversations of dissonance-minimizing agents. Given their current beliefs, agents make statements, tune them to the statements of their associates, and then revise their beliefs. We characterize the...

We argue that migrants played a significant role in the diffusion of the demographic transition from France to the rest of Europe in the late 19th century. Employing novel data on French immigration from other European regions from 1850 to 1930, we find that higher immigration to France...

The COVID-19 vaccines played a pivotal role in safeguarding populations. Yet, vaccine hesitancy remained a significant barrier to increasing coverage rates, as many high-income countries faced prolonged vaccine refusal campaigns. In Japan, vaccine doses were administered under a reservation...

In this paper, we study how forced migration impacts the in-group and out-group social capital of Syrian refugees and the host population in Northern Lebanon by administering a novel survey experiment in which we manipulate the salience of the migration experience (for refugees) and the refugee...

Economic growth is propelled in part by the accumulation of different kinds of capital, including social capital in its several guises. This paper considers the interplay between financial crises and various aspects of social capital which, if it is allowed to depreciate, can undermine economic...
