This paper explores theoretically the formation of a system of cities in which ports affect the spatial location and the size of cities. We use a complex systems and economic geography approach to generate 2D cellular automata to simulate the formation of the landscape of urban agglomerations...

Does the ranking of Covid-19 cases by municipality follow Zipf’s law (i.e. an estimated Pareto exponent of one)? This note tries to answer this question using daily data from Brazil for the Mar 30, 2020 -Oct 22, 2021 period. We used a Poisson Pseudo Maximum Likelihood (PPML) estimator and the...

Improving the energy efficiency in the urbanization process is particularly important for China to pursue high-quality economic growth. Urbanization may change a city’s spatial structure, transforming it from a monocentric city to a polycentric one. Based on the panel data of China’s...

Larger cities typically give rise to two opposite effects: tougher competition among firms and higher production costs. Using an urban model with substitutability of production factors and pro-competitive effects, I study the response of the market outcome to city size, land-use regulations, and...

We study decentralized and optimal urbanization in a simple multi-sector model of a rural-urban economy focusing on productivity differences and internal trade frictions. We show that even in the absence of the typical externalities studied in the literature, such as agglomeration, congestion or...

This study uses a large firm-level data set covering more than 80 countries to explore the effects of firm-size, city-size, and government-size on perceived and experienced corruption. Four points summarize our main findings, which seem instructive and new. First, there is a broad structural...

We present a comprehensive agent-based model of a closed system of cities. The model includes two types of agents - employees and firms. Firms compete for workers and make decisions concerning what to produce and whether to adopt innovations. Individual employees make migration decisions. Some...

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...

According to Gibrat’s law for cities, population shocks have permanent effects on city size. I examine this implication by analysing the persistence of observed population shocks: German military casualties in WWI by municipality of birth. I find a strong negative effect of military casualties...

If one ranks cities by population, the rank of a city is inversely related to its size, a well-documented phenomenon known as Zipf's Law. Further, the growth rate of a city's population is uncorrelated with its size, another well-known characteristic known as Gibrat's Law. In this paper, I show...

The completion of transportation infrastructure frequently takes many years and occurs gradually. How does the gradual construction of transportation infrastructure affect the distribution of economic activity across the sites it serves? I examine the long-run effects of the timing of railroad...

The paper deals with the question of whether fiscal transfers received by cities can be justified by a higher cost of producing publicly provided goods. In the model, increasing the population density implies both a higher output per capita due to agglomeration economies and a higher cost of the...

In a theoretical model local jurisdictions provide a public input and a public consumption good financed by a tax on capital income. When deciding about tax rate and budget structure the jurisdictions will generally respond to each others fiscal choices irrespective of whether the policy is more...

In this paper we show that the recent model by Duranton (AER, 2007) performs remarkably well in replicating the city size distribution of West Germany, much better than the simple rank-size rule known as Zipf's law. The main mechanism of this theoretical framework is the "churning" of industries...

We construct a unique data set to analyze whether or not a large temporary shock had an impact on German city growth and city size distribution. Following recent work by Davis and Weinstein (2001) on Japan, we take the strategic bombing of German cities during WWII as our example of such a...

We study the US city size distribution over space. This paper makes two contributions to the empirical literature on city size distributions. First, this study uses data from different definitions of US cities in 2010 to study the distribution of cities in space, finding significant patterns of...

This paper develops a model with an endogenous number of cities to explore whether local governments establish the optimal city size when key activities in the city are associated with emissions that harm consumers. In contrast to extant research, our model is fully micro-founded with respect to...

We present the first ever large-scale snapshot of urban residential segregation in India at the neighborhood-scale. Our analysis from 147 largest cities in contemporary India shows how caste-based residential segregation is independent of city size (our sample includes all cities in India with...

This paper studies urban growth in Korean cities. First, I document that population growth patterns change over time and that the current population distribution supports random urban growth. I confirm two empirical laws-Zipf's law and Gibrat's law-both of which hold in the period of 1995-2015,...

This paper introduces a new city-level panel dataset constructed using satellite nighttime light imagery and grid population data. The dataset contains over 1,500 cities covering 43 economies of Asia and the Pacific from 1992 to 2016. With the dataset, we perform a variety of analyses for Asia...

This paper employs a new definition of urban areas as functional economic units developed by the OECD in collaboration with the European Union to investigate the size and sources of productivity disparities across urban areas in Great Britain. We use data from the UK Annual Survey of Hours and...

This paper studies how the changing geographic distribution of skilled workers in the US affects theoretical models that use Gibrat's law to explain the size distribution of cities. In the empirical literature, a divergence hypothesis holds that college share increases faster in cities where...

The current outbreak of novel coronavirus disease 2019 (COVID-19) poses an unprecedented global health and economic threat to interconnected human societies. Until a vaccine is developed, strategies for controlling the outbreak rely on aggressive social distancing. These measures largely...

This paper examines the relationship between city size, migration, and urban income inequality using the 1% sample of the 2005 Census in the People's Republic of China (PRC). We calculate various measures of within-city income inequality for 252 PRC cities. It is found that city income...

We estimate the relationship between urban spatial expansion and its socio-economic determinants in Lombardy, the most urbanised region of Italy (and one of the most urbanized of the European Union), at the municipality level. Test results suggest that this relationship varies significantly...

In what sense are institutions a deep determinant of growth? In this paper, we address this question by examining the relationship between city growth and institutional reform in 19th century Germany, when some cities experienced deep institutional reform as a result of French rule. Employing an...

Agglomeration economies have a relevant impact on local labour markets. The interaction of workers and firms in dense urban areas may generate productivity advantages that result in higher wages. City size has an important impact on the relative bargaining power of workers and firms in the...

We study decentralized and optimal urbanization in a simple multi-sector model of a rural-urban economy focusing on productivity differences and internal trade frictions. We show that even in the absence of the typical externalities studied in the literature, such as agglomeration, congestion or...

This study assesses the effects of urban governance structure on the spatial expansion of metropolitan areas. A more fragmented governance structure, represented by a high number of administrative units with decision power on land use per inhabitant, is expected to increase the competition...

Models of city systems based on market theories are unable to replicate their size distribution. The stochastic process approach to size distribution, which asserts proportional growth, does not provide a strong economic foundation. Hence an apparent irreconcilability. We propose that since...

Urbanisation in Ethiopia is increasing rapidly. This paper uses city-level data to investigate the evolution of Ethiopia’s city size distribution from 1984 to 2012, using descriptive statistics and time-series Gini coefficient calculations. Over that period, the study found that overall city...

As a country transitions from a lower order of development to a higher order of development, it undergoes a structural transformation. Accordingly, the spatial economy transforms from a system organized around smaller economic units distributed throughout the countryside, to one comprising...
