Datasets

• Market Microstructure Database Xetra (with T. Johann, E. Theissen, C. Westheide, and L. Zimmermann)
  One problem faced by researchers interested in liquidity is that measuring it oftentimes requires intraday high-frequency data. Such datasets are expensive and, because of their size, hard to work with. We address this problem for the German equity market by providing a database that contains various daily market-microstructure measures of liquidity on the stock level for all stocks contained in the CDAX index from 1999 to 2013 traded on Xetra. The database is available free of charge to qualifying researchers. Find out more here: https://www.ifk-cfs.de/research/databases/market-microstructure-database-xetra.html
