Long-Run Effects of Dynamically Assigned Treatments: A New Methodology and an Evaluation of Training Effects on Earnings
van den Berg, Gerard J.; Vikström, Johan - 2019
We propose and implement a new method to estimate treatment effects in settings where individuals need to be in a certain state (e.g. unemployment) to be eligible for a treatment, treatments may commence at different points in time, and the outcome of interest is realized after the individual...

An Evaluation of Public Employment Programmes in the East German State of Sachsen-Anhalt
Lechner, Michael; Eichler, Martin - 1999
In East Germany, active labour market policies (ALMPs) are used on a large scale to contain fast rising unemployment after unification. This paper evaluates the effects for participants in public employment programmes (PEPs), that are an important part of ALMPs. It focuses on individual...

A martingale representation for matching estimators
Abadie, Alberto; Imbens, Guido W. - 2009
Matching estimators are widely used in statistical data analysis. However, the distribution of matching estimators has … matching estimators. This representation allows the use of martingale limit theorems to derive the asymptotic distribution of … matching estimators. As an illustration of the applicability of the theory, we derive the asymptotic distribution of a matching …

The Effect of Firms' Partial Retirement Policies on the Labour Market Outcomes of Their Employees
Huber, Martin; Lechner, Michael; Wunsch, Conny - 2013
In this paper, we assess the impact of firms introducing part-time work schemes for gradual labour market exit of elderly workers on their employees' labour market outcomes. The analysis is based on unique linked employer-employee data that combine high-quality survey and administrative data....
