    A multilateral approach to modelling the New Zealand dollar

    Exchange rates between any two bilateral countries are forecasted using models involving only the two bilateral countries. Prince developed a multilateral approach to exchange rate determination. He modelled the New Zealand dollar by introducing the USD and Euro into existing bilateral exchange rate models. The global significance of these two currencies means that changes to these two currencies impact currencies worldwide. This approach gave better exchange rate forecasts than existing bilateral models.

    Investigating the odds of loan acceptance during and after the GFC

    By looking at the data for a private lending firm in the US, Prince investigated the factors influencing loan application success for US residents during and post-GFC. Using logistic regressions, employment years and debt-to-income ratios were determined as the two key factors in determining loan application success during both time periods.

  • Horticulture seasonal labour demand and supply forecasts

    By Mark Dean and Dion Gamperle

    NZIER were required to forecast potential labour market shortages during the busy seasonal harvest periods. The project required a range of skills from dynamic labour market modelling, survey design, data collection and econometric estimation of wage elasticities.

    This was a very detailed, technical project which culminated in an accessible report that was very well received by our clients.

      This is a study of the impact of locating next to a rich area on residential satisfaction of the residents of the relatively poor area. The results, which have been frequently used in different pieces of advice (provided to different stakeholders), are very useful for the policy in order to provide enduring neighbourhoods in Auckland.
      Torshizian, Eilya & Arthur Grimes. 2014. Residential Satisfaction, Crowding and Density: Evidence over Different Geographic Scales in Auckland, Presented to NZ Association of Economists conference, Auckland, July.
      This is a causal study of the impact of intensification on Aucklander’s satisfaction with their residential environment. The study provides the most relevant definition for neighbourhood boundaries for Aucklanders. Since intensification is one of the main instruments of the council, the results of this paper are very useful for the council’s planning regulations.
    • Torshizian, Eilya & Arthur Grimes. 2013. Is residential satisfaction a matter of perceptions?, Presented to Resilient Urban Futures, The university of Otago.
      This study comparesthe information content of subjective versus objective measures of household crowding when estimating people’s evaluation of satisfaction with their residential environment.

    Social policy

    Gail has been involved in a variety of outputs that were focused on bringing evidence to bear on some of New Zealand's major social challenges. These included overseeing the production of evidence briefs on topics such as children of gangs, children of prisoners, family resilience, non-health costs of obesity and family violence. The purpose of the briefs was to bring together what is known and unknown about these key social policy areas to inform interventions.

    Tax system

    In her work with Inland Revenue, Gail oversaw the design and production of research and evaluation to better understand compliance behaviour. Projects included small business decision-making in relation to tax debt, attitudes towards the 'hidden economy', and impact of information sharing across government.    

    Systems approaches

    Gail has worked in cross-discipline teams to apply systems thinking approaches to a range of different areas including family violence, regional development, sustainability, and agricultural land use change.

    Māori Land Service Programme (Oct 2014 to May 2015)
    Shane was the Director of a cross-agency programme set up to (1) transfer services out of the Māori Land Court (MLC), and (2) establish an integrated front door to services for Māori land owners. His principal role in this engagement was to establish a PMO and stabilise and re-define the programme, which began in 2013. His team then completed an assessment of services delivered by the MLC and developed a target operating model and design brief for a business case due later this year.

    Shared Services Reform (Jul 2013 to Mar 2014)
    Shane’s principal role in this engagement was to lead machinery of government on, and then work with subject matter experts to develop, a strategy to transform transactional administrative and support services for the Public and Non-Public service. The strategy proposed a two-part reform to deliver significant and sustainable financial and non-financial benefits and directly support the Government’s key goals.

    Public Trust Transformation (May 2013 to Jun 2013)
    Working across the business, Shane designed a new service that enabled the Trust to better leverage government funding and significantly reduce closure time for estates. In piloting, this new service reduced the average closure time for estates from approx. 100 to less than 30 days.

    Inland Revenue Business Transformation (Sep 2012 to Mar 2013)
    Shane was the Process Lead for the Re-engineer Deduct at Source Initiative. Working across the business, his team developed, for incorporation into the IRD business case, a high-level service design to transform the way tax, information, and other obligations are collected at source from individual non-business taxpayers.

    Tourism contribution
    Daniel estimated the tourism contribution to the Australian State/Territory economy which was published as State/Territory Tourism Satellite Account (TSA).

    Economic impact of terrorism on Bali

  • Economic modelling of the Waimea community dam

    By Erwin Corong

    The Nelson Regional Economic Development Agency asked us to review and update economic assessments of the Waimea Community Dam, proposed for the Lee Valley south of Richmond. The dam would provide water storage of about 13 million cubic metres, sufficient to meet unrestricted demand and enhanced environmental minimum flows in drought conditions in the Waimea River. Along with cost benefit analysis (CBA), we used our TERM-NZ (bottom up regional) CGE model of the New Zealand economy to estimate the potential economic costs of non-augmentation and the likely long term economic benefits of dam installation and expansion of irrigated areas in the Waimea plains.
