Preprint
In this paper we study the finite sample and asymptotic properties of various weighting estimators of the local average treatment effect (LATE), several of which are based on Abadie (2003)'s kappa theorem. Our framework presumes a binary endogenous explanatory variable ("treatment") and a binary instrumental variable, which may only be valid after...

We study the peer effects on school achievement exploiting the network structure of friendships within a classroom. In particular, we focus on the role of heterogeneity in network peer effects by accounting for network-specific factors and different driving mechanisms of peer behavior. For this purpose, we propose a novel Instrumental Variable-Mini...
Article
A simple shrinkage method is proposed to improve the performance of weighting estimators of the average treatment effect. As the weights in these estimators can become arbitrarily large for the propensity scores close to the boundaries, three different variants of a shrinkage method for the propensity scores are analyzed. The results of a comprehen...
Article
Interventions with multivalued treatments are common in medical and health research, such as when comparing the efficacy of competing drugs or interventions, or comparing between various doses of a particular drug. In recent years, there has been a growing interest in the development of multivalued treatment effect estimators using observational da...

Article
Using unique data from an internet-based foreign-exchange trading platform, we show that the black market efficiently incorporated public information on the state of the Belarusian economy during the Balance of Payments crisis of 2011. Between May and October 2011, the government repeatedly devalued the Belarusian ruble and eventually abandoned its...
Article
This paper provides doubly robust estimators for treatment effect parameters which are defined in a multivalued treatment effect framework. We apply this method to the unique dataset of the 1970 British Cohort Study (BCS70) to estimate returns to various levels of schooling. The analysis is carried out for female and male samples separately to capt...
Article
We propose a simple way to improve the efficiency of the average treatment effect on propensity score based estimators. As the weights become arbitrarily large for the propensity scores being close to one or zero, we propose to shrink the propensity scores away from these boundaries. Using a comprehensive Monte Carlo study we show that this simple...
Article
This paper provides doubly robust estimators for treatment effect parameters which are defined in multivalued treatment effect framework. We apply this method on a unique data set of British Cohort Study (BCS) to estimate returns to different levels of schooling. Average returns are estimated for entire population, as well as conditional on having...
Article
Full-text available
This paper focuses on the role personality traits play in determining individual unemployment duration. We argue that a worker’s job search intensity is decisively driven by her personality traits, reflected in her propensity to motivate and control herself while searching for a job. Moreover, personality traits, in as far as they can be signaled t...
Article
In this study, I estimate the average causal treatment effect of grade retention on several educational outcome variables, such as completion of upper secondary school, graduation grades in math and German, as well as average final grade using a data set from Germany. The analysis relies on Conditional Independence Assumption. I use doubly robust m...
Article
This paper focuses on the role of noncognitive skills play in determining the suc- cess of unemployed workers flnding and keeping a job. We argue that a worker's job search intensity not only relies on the conventional determinants discussed in the job search literature but is also decisively driven by her noncognitive skills, re∞ected in her prope...
