Firm Surveys
Since 1993, IWH has conducted regular surveys among a fixed group of firms in the manufacturing and construction industry to collect individual data on economic activity. Until 2012, the surveys were carried out on a monthly basis with the construction and the manufacturing industry taking turns.
Since 2013, both surveys are conducted quarterly. They are based on a rotating panel of about 400 companies in each industry. The response rate is approximately 75%.
The results are published regularly (every month until 2012, quarterly since 2013) as reports, including figures and standard table as press releases and in the IWH publication "Wirtschaft im Wandel".
