Some things we do

Impact Assessment and Cost Benefit Analysis

Assessing the impacts, costs and benefits of growth, change or some shock is vital to developing an understanding of how an economy, sector or region operates and responds to external forces. M.E adopts a holistic approach to economic, social and environmental impact assessments and cost benefit analysis. We focus on identifying the key components and drivers, the feedbacks and relationships and any sensitivity. We apply leading edge and international best practice modelling techniques.

Economic Impact Assessment

M.E has proven expertise in determining the regional and national economic impacts of events, facilities, developments and policies. By combining expenditure and funding data with our proprietary models (Multi-Regional Input-Output (MRIO) model, Computable General Equilibrium (CGE) model and System Dynamics (SD) model), we are able to assess the short, medium and long term direct and flow-on effects of change. We report the net effects using economic variables such as employment, value added/GDP and total sales.

Social Impact Assessment

For some projects, understanding the impacts on communities and society is an important consideration. M.E is experienced in identifying and quantifying the social impacts of alternative development proposals and policies. M.E has been instrumental in getting the concept of social and functional amenity adopted by the Environment Court as a key component in assessing the effects of developments.

Environmental Impact Assessment

Understanding environmental impacts is important in progressing towards sustainable development. Our research in this field focusses on the impacts of various resource use profiles (intensity and scale) on environmental variables and in particular, measuring changes in environmental indicators, emissions, wastes, pollutants and energy use.

Cost Benefit Analysis

M.E applies CBA (and Cost effectiveness Analysis) to identify the relative benefits of different development options, defining the relevant (explicit and implicit) costs and benefits, quantifying these where possible, and monetising where appropriate. This analysis is often used to identify the Benefit Cost Ratio (BCR). In these studies, it is important to ensure robust definition of the range of costs and benefits, and apply appropriate time frames, discount rates, and geographic extent.

Examples of our work:
  • Ministry of Economic Development (Economic Impact of Rugby World Cup 2011)
  • Ministry of Transport (Social Impact of Road Pricing Strategies)
  • Ports of Auckland Ltd (Economic Role of the Ports of Auckland Limited)
  • Auckland Regional Council (Economic Impact of Aquaculture in Auckland)
  • Auckland Council (Auckland Air Quality Domestic Options – Cost Benefit Analysis)
