Methods

IPP research uses a variety of methods for analysing and for evaluating public policy, mainly based on the use of statistical data.

A wide spectrum of methods

The favoured methods of the IPP include micro-simulation of the tax and transfer system, impact studies relying on “natural” or “controlled” experiments, structural models, macro-simulation and computable general equilibrium models, theoretical economic analysis, cost-benefit analysis and experimental economics. The capacity to mobilise any of these methods according to the data available and to the policy studied is at the heart of the IPP’s expertise.

Data protection

The work by the IPP mainly rests upon the use of individual data from surveys or administrative sources. The Institute has adopted a very strict approach to protect data privacy and respect the rules of statistical confidentiality.
