Internet Data

One of the most important consequences of digitization is that it allows us to store and process enormous amounts of data. New methodological challenges arise and old ones are revisited, together creating new opportunities for research. Most of this type of new digital data, although publicly available, is stored in proprietary data silos not ready to use for empirical analyses by outsiders. The IDSC performs advocacy for the availability of such data to social science and develops tools and skills for data extraction in order to facilitate the use of this type of data for researchers.

Our own research activities prove the usefulness of internet data research. As an example, we offer the “Toll Index,”  an experimental monthly indicator for the German business cycle. It measures the monthly transportation activity performed by heavy transport vehicles across the country and has highly desirable availability properties (insignificant revisions, short publication lags) as a result of the innovative data collection technology. The data is available via the IDSC data repository system.

This new index is an excellent example of technological, innovation-driven economic telemetry, which can be exploited for economic forecasting.

For details on the underlying nowcasting method of the Toll Index see http://onlinelibrary.wiley.com/doi/10.1002/for.1262/abstract


Data Provision / Data Upload

The IDSC strives to offer an ever-increasing inventory of original data for labor market research. In addition to exclusive provisioning of datasets initiated by IZA, our Research Data Center offers datasets uploaded in its repository by researchers themselves.  The data repository provides an online-tool for self-determined documentation, upload and publication of research data. It enables researchers to have their data, metadata and outputs preserved longitudinally and helps to provide it to the academic community for further research or to fulfill publication requirements by academic journals. In doing so, researchers obtain a DOI for the proper citation of their dataset and associated publications. This includes survey data, administrative data, experimental data, tabular data and outputs of statistical analyses. Syntax files may also be submitted. All uploaded research data and documentation will be preserved and distributed by the IDSC of IZA in a manner fully controlled by the researcher who deposits the data.

All data collected are accessible to the scientific community as scientific use files for scholarly analyses free of charge.

Data Citation

The IZA Institute of Labor Economics recognizes the importance of proper citation of data as it

  • acknowledges the author's sources
  • makes identifying data easier
  • promotes the reproduction of research results
  • allows the impact of data to be tracked
  • provides a structure which recognizes and can reward data creators
  • increases impact and prestige of publications.

Based on this we worked out a data citation convention which takes into account prior work done by respectable institutions and should become a standard for dataset citation in scientific literature. IZA adopts the data citation conventions across all of its publications: IZA Discussion Paper Series, IZA Journals, IZA World of Labor, etc.

Data Access via JoSuA

Remote access is an option when data are not directly available to researchers. The IDSC has developed JoSuA, an innovative job submission application, which can be implemented by data providers in order to offer secured remote access to their data.

Originally designed in order to grant international researchers access to German labor market data, JoSuA has matured into a flexible and scalable instrument of data analysis of configurable degree of automation designed to fit the data security provisions of each individual data provider.

JoSuA is not only used at IZA, but also at the Research Data Center of the German Federal Employment Agency (BA) at the Institute for Employment Research (IAB). Via JoSuA researchers have access to a broad variety of IAB data sets, e.g., the IAB Employment Panel.

The IDSC also runs a remote computing service on behalf of the Research Data Center of the German Institute for Educational Quality Improvement (IQB). This collaboration allows for remote access to a variety of data sets focused on education, e.g., PISA data, etc.

At IZA, we offer various data collections for online data analysis that can be accessed via JoSuA. Furthermore, our network of research fellows exclusively benefits from using German data sets offered by the Federal Statistical Office (Destatis).

For questions concerning our dataset portfolio or acquiring JoSuA, please contact idsc@iza.org.


Annual DDI User Conference (EDDI)

Initiated by the IDSC of IZA and the Leibnitz Institute for the Social Sciences (GESIS) the Annual European DDI User Conference (EDDI) provides a discussion forum for European Members of the Data Documentation Initiative (DDI), an actively developed standard specification able to address the documentation and management of data across its entire life cycle. The conference series is run jointly together with the DDI alliance.

IDSC Data Seminar

With its on-demand Data Seminar, IZA fosters cooperation and creates synergies by providing a forum for researchers to exchange knowledge about datasets that are vital for research, or about their own data, which have often been put together with the aid of the IDSC. Researchers interested to present their data sets or request a data presentation should contact idsc@iza.org.
