John M. Abowd and Ian M. Schmutte : “The Advantages And Disadvantages Of Statistical Disclosure Limitation For Program Evaluation”
Abstract: This paper formalizes the manner in which statistical disclosure limitation (SDL) hinders empirical research in economics. We also highlight a hitherto unappreciated advantage of SDL, formal privacy models, and synthetic data systems: they can serve as a defense against model overfitting and false­discovery bias. More specifically, a synthetic data validation system can – and we argue should – be used in conjunction with systems in which researchers register their research design ahead of analysis. The key insight is that privacy­protected data can be used for model development while minimizing risk of model overfitting. To demonstrate these points, we develop a model in which the statistical agency collects data from a population, but publishes a version in which the data that have been intentionally distorted by some SDL process. We say the SDL process is ignorable if inferences based on the published data are indistinguishable from inferences based on the unprotected data. SDL is rarely ignorable. If the researcher has knowledge of the SDL model, she can conduct an SDL­aware analysis that explicitly corrects for the effects of SDL. If, as is often the case, if the SDL model is unknown, we describe circumstances under which SDL can still be learned.

Vilhuber presents on Crowdsourcing Codebook Development and Enhancements in CED²AR @ U.S. Census Bureau

Benjamin Perry, Venkata Kambhampaty, Kyle Brumsted, Lars Vilhuber, & William C. Block: “Crowdsourcing Codebook Development and Enhancements in CED²AR”
Abstract: Recent years have shown the power of user­sourced information evidenced by the success of Wikipedia and its many emulators. This sort of unstructured discussion is currently not feasible as a part of the otherwise successful metadata repositories. Creating and augmenting metadata is a labor­intensive endeavor. Harnessing collective knowledge from actual data users can supplement officially generated metadata. As part of our Comprehensive Extensible Data Documentation and Access Repository (CED²AR) infrastructure, we demonstrate a prototype of crowdsourced DDI on actual codebooks. While the system itself is more general, the demonstrated implementation relies on a set of linked deployments of the basic software on web servers. The backend transparently handles changes, and frontend has the ability to separate official edits (by designated curators of the data and the metadata) from crowd­sourced content. The implementation allows a data curator, such as a statistical agency, to collect and incorporate improvements suggested by knowledgeable users in a structured way.
