Nazila Alinaghi: Research Fellow in Public Finance

Dr Nazila Alinaghi
Dr Nazila Alinaghi, Research Fellow in Public Finance

Dr Nazila Alinaghi joined the Chair in Public Finance in October 2017 after completing her PhD on the topic of taxes and economic growth at University of Canterbury, where she was awarded a UC PhD Scholarship and several other prizes for her papers. Since joining the CPF, Nazila has been working on several topics, including tax and transfer microsimulation modelling (minimum wage policy), estimating taxable income elasticities, and tax compliance. During 2019, she has produced three working papers. One of these (produced with Professors Creedy and Gemmell) was awarded the New Zealand Economic Policy Prize at the New Zealand Association of Economists Annual Conference. She also completed a project for which she received a research grant from the International Initiative for Impact Evaluation (3ie), funded by the Bill & Melinda Gates Foundation (Washington DC, USA), with the project outcome published in a peer-reviewed journal. Nazila contributed to the successful application to the 2019 MBIE Endeavour Fund, helping the CPF team secure over $1 million to undertake a three-year research project on measuring income inequality, poverty, and mobility in New Zealand.

Amy Cruickshank: PhD student

Research project: Government policy toward charitable giving in New Zealand.

Abstract: Amy’s thesis, supervised by Norman Gemmell and Peer Skov (AUT), is exploring charitable giving behaviour in New Zealand and how this behaviour is influenced by government policy, in particular, the effectiveness of tax incentives for individual donations, payroll giving schemes, and direct government grants to registered charities. The research will be informative for policymakers when considering policy settings in relation to charitable giving and government grant schemes, as well as the philanthropic sector when devising fundraising strategies. The analysis will be based on unit record data of donation tax credit claims and workplace giving from Inland Revenue and data on charity grant applications and finances from the Department of Internal Affairs.

Chris Ball: PhD student

Research project: Labour supply responses to policy reform using behavioural microsimulation modelling.

Abstract: Chris’s PhD research, supervised by John Creedy and Norman Gemmell, is examining labour supply responses to tax-and-transfer changes using microsimulation modelling. The research consists of four key contributions: 1) developing high-quality synthetic data for use in microsimulation modelling; 2) investigating parameter restrictions to ensure preference parameter estimates are consistent with economic theory; 3) extending the Random Utility Random Opportunity (RURO) discrete choice set to include transfer receipt; and 4) designing new methods to evaluate behavioural microsimulation modelling results.
