Inquiry into population growth, migration and agglomeration

What role do housing costs, migration and the benefits/problems of agglomeration have on raising economic productivity?

The goal of raising economic productivity is of importance both nationally and internationally, but the interplays between productivity, housing costs, migration and the benefits/problems of agglomeration are very complex. This Inquiry will develop a comprehensive evidence base grounded on evidence reviews, qualitative methods and econometric modelling.

Population growth and mobility in Australia: implications for housing and urban development policies

This project will uncover the key drivers of population growth and mobility in Australia in the recent decade. Drawing on a mix of quantitative and qualitative approaches, the project will shed light on the implications of recent population trends for housing and urban policy development.

Relationships between metropolitan, satellite and regional city size, spatial context and economic productivity

The project will provide an evidence base to support policy development options relating to agglomeration economies in Australia’s cities and regions. Based on econometric analyses of Australian, EU and US datasets, it will seek to understand at what population and geographic scales agglomeration economics begin to alter the economic productivity of cities, and at what stage these advantages reduce.

Population growth, regional connectivity, and city planning – international lessons for Australian practice

This project examines international models of metropolitan and regional planning, focusing on governance, spatial organisation, and connectivity, to identify drivers of economic and social outcomes. It identifies lessons for Australian practice through a review of capital city and regional planning frameworks, and interviews with planners across three levels of government.

Agglomeration effects and housing market dynamics

This project aims to develop an understanding of how jobs and skills concentration affect labour productivity and labour’s housing costs in Australia. This project quantifies agglomeration benefits in the form of labour productivity gains from employment density and population growth. By considering skills and income, it will use econometric modelling to understand how benefits are distributed; and whether productivity gains are absorbed by higher housing costs, and how skill effects are linked to migration policy.
