        AB  - This paper reviews the main identification and estimation strategies for microeconomic policy
evaluation. Particular emphasis is laid on evaluating policies consisting of multiple
programmes, which is of high relevance in practice. For example, active labour market
policies may consist of different training programmes, employment programmes and wage
subsidies. Similarly, sickness rehabilitation policies often offer different vocational as well as
non-vocational rehabilitation measures. First, the main identification strategies (control-forconfounding-
variables, difference-in difference, instrumental-variable, and regressiondiscontinuity
identification) are discussed in the multiple-programme setting. Thereafter, the
different nonparametric matching and weighting estimators of the average treatment effects
and their properties are examined.
