Cities are among the best examples of complex systems. The adaptive components of a city, such as its people, firms, institutions, and physical structures, form intricate and often non-intuitive interdependencies with one another. These interdependencies can be quantified and represented as...

A lack of affordable housing is a growing crisis for many communities in the US, particularly in urban neighborhoods with constrained housing markets. We discuss the housing imbalance and affordability crisis in the San Francisco Bay Area. Land use regulations are the biggest impediment in...

Does national market size matter for industrial structure? Round One (Krugman) answered in the affirmative: Home market effects matter. Round Two (Davis) refuted this, arguing that an assumption of convenience - transport costs only for the differentiated goods - conveniently obtained the...

Interest in analyzing the dynamics of the Great Recession among regional economists has largely focused on ‘regional resilience.’ This concept, while still not fully formed, considers the relationship between regional characteristics and the regional response to economic shocks, particularly...

We develop a frictional labor market model with multiple regions and heterogeneous firms to study how frictions impeding labor mobility across space affect the joint allocation of labor across firms and regions. Bringing the model to matched employer-employee data from Germany, we find that...

The city of Shenzhen has been labeled as China's Silicon Valley. On August 18, 2019, Chinese authorities released a policy document stating that China will make Shenzhen a model city for others to follow. After an extensive literature review on relevant topics, including economic development,...

This paper integrates daytime and nighttime satellite imagery into a spatial general-equilibrium model to evaluate the returns to investments in new motorways. Our approach has particular value in developing-country settings in which granular data on economic activity are scarce. To demonstrate...

Structural transformation and regional convergence in U.S. income have been long-standing trends. Caselli and Coleman (2001) discovered that 60% of regional convergence between the U.S. South and North from 1940 to 1990 is due to structural transformation. Our replication confirms these robust...
