Research

Diana is currently completing her PhD in economics in the area of interregional migration in Australia where her overall research objective seeks to understand what makes people want to stay, move away from or move into a region. She is under the primary supervision of Dr Riccardo Welters, Associate Professor in Economics at the College of Business, Law and Governance, Division Tropical Environments and Societies and Theme Leader of ‘Sustainable Development’ at the Cairns Institute, JCU.

Having lived in regions all her life and experienced first hand how push and pull factors influence decision making and impact on the functionality of those regions, Diana hopes her research findings will better guide practitioners and policy makers who seek strategies to the challenges of attracting and retaining varied skilled people in regional Australia.

As part of her research Diana attempts to better define what is meant by migration. Whilst migration definitions are offered, there are complexities to its dimensions. Margins are blurred temporally, spatially and socially which means there’s no clear consensus on its measure. As such within Diana’s overarching objective to identify the determinants of interregional migration within Australia, she seeks to explore three research questions:

1) Who decides? To understand better what motivates people to move between regions, we need to firstly identify who is making that decision. Castorina and Welters (2022) have now published their findings on this research question here: https://doi.org/10.47260/bae/917

2) Does distance matter? Here we look at the role of distance in migration decisions. We utilise econometrics to devise a method to separate short distance migrants from long distance migrants as different displacement impacts are experienced by the two.

3) Does space matter? Misspecification in our migration models may be present given we are working with cross-sectional data which are susceptible to spatial effects. We employ geographically weighted regressions to explore if spatial heterogeneity is present within our data. Of which without otherwise, bias may be present within our empirical conclusions.
