Measuring the economic impact of immigration: A scoping paper

Abstract

This discussion paper has three objectives. Firstly, it provides a brief review of recent international empirical research on the labour market impact of immigration. The synthesis of this literature is facilitated by reference to the results from a recent meta-analysis of the impact of immigration on wages. Secondly, the paper briefly reviews international research on other dimensions of the economic impact of immigration, namely productivity and technical change, trade and international relations, the fiscal impact, socio-economic impacts and externalities, and economy-wide (general equilibrium) effects. The approach adopted in considering each of these impacts is to identify the main issues associated with the particular impact, followed by key international references and, where available, New Zealand references on the particular type of impact. The gaps in NZ research are then identified along with any difficulties with the data available for replicating the international studies in New Zealand. Thirdly, the paper seeks to identify feasible (in terms of data availability) suggestions for further research that would add to our knowledge of the economic impact of immigration in New Zealand.
