In this paper we investigate GMM-based unit root inference in an autoregressive panel data model with individual-specific levels. We consider tests based on GMM estimators of the AR parameter and moment condition tests. The limiting distributions of the corresponding test statistics are derived...

The objective of the paper is to investigate and compare the performance of some of the unit root tests in micro-panels which have been suggested in the literature. The framework is an autoregressive panel data model allowing for heterogeneity in the intercept but not in the autoregressive...

This work takes a new look at the econometrics of the national-level macroeconomic relationship between inequality and growth. It focuses, in particular, on the effects of specification choices, estimation method and sample selection. It concludes that there is no robust relation running from...

Most evaluation studies of active labour market policies (ALMP) focus on the microeconometric evaluation approach using individual data. However, as the microeconometric approach usually ignores impacts on the non-participants, it should be seen as a first step to a complete evaluation which has...
