|April 2015||Estimation of Treatment Effects from Combined Data: Identification versus Data Security|
with Tatiana Komarova, Denis Nekipelov
in Economic Analysis of the Digital Economy, Avi Goldfarb, Shane M. Greenstein, and Catherine E. Tucker, editors
The security of sensitive individual data is a subject of indisputable importance. One of the major threats to sensitive data arises when one can link sensitive information and publicly available data. In this paper the authors demonstrate that even if the sensitive data are never publicly released, the point estimates from the empirical model estimated from the combined public and sensitive data may lead to a disclosure of individual information. Their theory builds on the work in Komarova, Nekipelov and Yakovlev (2011) where they analyze the individual disclosure that arises from the releases of marginal empirical distributions of individual data. The disclosure threat in that case is posed by the possibility of a linkage between the released marginal distributions. In this chapter, they...
|July 2014||How Persistent Are Consumption Habits? Micro-Evidence from Russia|
with Lorenz Kueng: w20298
We use two quasi-natural experiments, the rapid expansion of many markets after the collapse of the Soviet Union and the Anti-Alcohol Campaign in 1986, and a migrants research design to identify highly persistent habits in food and alcohol consumption. Large shocks to product availability and persistent habits produce large cohort differences in consumption. Placebo tests and descriptive statistics show that habits are formed when individuals start consuming a good regularly and remain largely unaffected afterward. We estimate that Russian male mortality will decrease by 23% within twenty years even without further interventions due to changes in alcohol consumption preferences.
