The effect of policy regulations in the short-term rental platform market on long-term rental prices
This paper examines the impact of short-term rental platforms on long-term rental prices in Sydney, focusing on the time before and after the announcement and implementation of Short-Term Rental Accommodation (STRA) laws. Using a difference-in-differences (DiD) regression model, we find significant effects on long-term rental prices, explained by the before and after effects of the introduction of the STRA laws, controlling for neighborhood and h…

City sizes and economic roles
The aim of this paper is to investigate the empirical correlations between inter-city population distribution, intra-city urban economic structures, and networked inter-city relationships to propose a conceptual classification framework for the Australian urban system. This paper sets the pre-COVID-19 benchmark for future research which will investigate the impact of COVID-19 on the economic geography of the Australian urban system. This research…
The role of analytical models and their circulation in urban studies and policy
Cities are so complex that we constantly build models to represent them, understand them and attempt to plan them. Models represent a middle ground between the singular configurations of cities and universal theories. This is what makes them valuable and prone to circulate (between places, institutions and languages) and evolve to adapt to new ideas, local conditions and/or other models. When it comes to analytical urban models (i.e. analytical r…
Immigrant settlement patterns, transit accessibility, and transit use
Measuring polycentricity via network flows, spatial interaction and percolation
Polycentricity, or the number of central urban places, is commonly measured by location-based metrics (e.g. employment density/total number of workers, above a threshold). While these metrics are good indicators of location ‘centricity’, results are sensitive to threshold choice. We consider the alternative idea that a centre’s status depends on its connectivity to other locations through trip inflows/outflows: this is inherently a network rather…
Urban scaling and the geographic concentration of inequalities by city size
Urban scaling laws summarise how socio-economic behaviours of urban systems may be predicted from city size. While most scaling analysis rests on using aggregate quantities (total incomes, GDP, etc.), examining distributions of these aggregate quantities (e.g. income distributions) could shed light on how socio-economic inequalities may correlate or be causally linked to city size. In this direction, this paper examines how geographic distributio…

The scaling of income distribution in Australia
Developing a scientific understanding of cities in a fast urbanizing world is essential for planning sustainable urban systems. Recently, it was shown that income and wealth creation follow increasing returns, scaling superlinearly with city size. We study scaling of per capita incomes for separate census defined income categories against population size for the whole of Australia. Across several urban area definitions, we find that lowest income…
