Robust synthetic control
… we present a robust generalization of the synthetic control method. A distinguishing feature of our algorithm is that of de-noising the data matrix via singular value thresholding, which renders our approach robust in multiple facets: it automatically identifies a good subset of donors, …

Evaluating the Impact of Economic Sanctions on South Africa: A Synthetic Control Approach
This research paper applies the synthetic control method to measure the economic cost of sanctions imposed on South Africa between 1985 and 1994. The economic sanctions imposed on South Africa between 1985 and 1994 by the United Nations, the United States of America, and the European Community …

The impact of assisted dying on suicidality: a synthetic control analysis of population suicide rates
… after assisted dying was introduced in 2002. The synthetic control method was chosen for the analysis, and additional European nations were included as placebos. The results show no change in suicide rates following the assisted dying policy change. A comparison of MSPE ratios with placebo …

Compared to What? The Effectiveness of Synthetic Control Methods for Causal Inference in Educational Assessment
<p>Synthetic control methods are an innovative matching technique first introduced within the economics and political science literature that have begun to find application in educational research as well. Synthetic controls create an aggregate-level, time-series comparison for a single treated …

A synthetic control model to estimate the effect of Colorado's Family Planning Initiative on abortions.
In 2009, the Colorado Family Planning Initiative provided IUDs at no cost for low-income women. The lowering of the price of an IUD could have the possible substitution effect of decreasing the number of abortions. Even though abortions decreased in Colorado after the initiative, we find no …

Essays on Econometrics and Policy Evaluation
… that study the statistical properties of synthetic control methods and their application to public policy evaluation and the digital economy. The first chapter, co-written with Ahmet Gulek, proposes a Synthetic Instrumental Variables (SIV) estimator for panel data that combines the …

Essays on complexity and causality in political science research
… The first essay examines the validity of the synthetic control method under complex analytical settings. The synthetic control method is increasingly being used to estimate the effect of an intervention when units of interest are at the aggregate level and there does not exist suitable control …

Causal inference with time-series cross-sectional data : with applications to positive political economy
… the average treated counterfactual and average control outcome do not follow parallel paths. The first chapter of this dissertation introduces the generalized synthetic control method that addresses this challenge. It imputes counterfactuals for each treated unit using control group information …

Improving utilization of maternal health related services: the impact of a community health worker pilot programme in Neno Malawi
… between a combined CHW intervention area and its synthetic control area using the synthetic control method. The synthetic control area (or synthetic counterfactual of the CHW) was the control area that was created from multiple available control sites where the CHW programme was not implemented to …

Essays in policy evaluation and labor economics
… The first chapter evaluates the effect of a gun control act in California. State legislators in the U.S. are striving to curb gun violence. A common approach is to extend the existing firearms ban list. This paper examines the effect of legislation restricting sales of selected firearms in …

Graphite-conjugated catalysts : bridging heterogeneous and homogeneous catalysts
… homogeneous catalysts allow a great degree of synthetic control over the catalytic active site. Moreover, the relative ease in spectroscopic characterization allows a mechanistic understanding of molecular catalysis at a level that is unattainable for heterogeneous catalysis. To bridge the …

Design and synthesis of nanocrystal heterostructures for optoelectronic applications
… high as 2.7%, 1.8% and 0.4% respectively. Better synthetic methods have produced nanocrystal emitters with higher quantum yield, boosting efficiency, while a better understanding of QD-OLED function has led to improved organic transport materials. These QD-OLED devices can also be redesigned using …
