In this paper we develop an exploratory non-parametric clustering model of spatial and/or spatio-temporal phenomena based on Kolmogorov entropy. The methodology will be tested using quarterly HPI (Housing Price Index) data for 350 plus cities in the US from the Federal Financing and Housing...

What is Housing Price to Income Ratio (HPIR) in the Indian context?It is the amount that can be spent by an individual or a household on purchase of new property (mainly house/residence) with the annual savings post taxes. For simple calculations it is assumed is that a. 10% of the income goes...

This paper proposes a novel methodology for delineating urban areas based on a machine learning algorithm that groups buildings within portions of space of sufficient density. To do so, we use the precise geolocation of all 12 million buildings in Spain. We exploit building heights to create a...

In the past decades, gentrification has transformed American central city neighborhoods. In this paper, I estimate a spatial equilibrium model to show that the rising value of high-skilled workers' time contributes to the gentrification of American central cities. I show that the increasing...

Metropolitan areas --unions of nearby built-up locations within which people travel on a day-to-day basis among places of residence, employment, and consumption--serve as a fundamental unit of economic analysis. But existing delineations of U.S. metro areas--including metropolitan Core-Based...

We document a number of striking features about the initial impact of the pandemic on local commerce across 16 US cities. There are two novel contributions from this analysis: exploration of neighborhood-level effects and shifts between offline and online purchasing channels. In our analysis we...

State preemption laws strictly limit local governments from regulating beyond their borders. Local governments, however, face a broad spectrum of challenges which cannot be confined to municipal borders. These challenges freely flow in and out of many local jurisdictions at the same time. The...

Urban economics, economic geography, and urban planning have widely recognized the importance of urban interactions, such as face-to-face communication or a convivial atmosphere, to understand urban phenomena. However, solitary contemplation is indispensable to enhance ability and creativity. I...

Current sources of data on rental housing – such as the census or commercial databases that focus on large apartment complexes – do not reflect recent market activity or the full scope of the U.S. rental market. To address this gap, we collected, cleaned, analyzed, mapped, and visualized 11...

We argue that the interaction between mobility and wealth provides a view that rationalizes low geographic migration rates, despite migration costs being lower than currently thought. We reach this conclusion by developing and solving a quantitative dynamic spatial equilibrium model with...
