The use of alternative high\u2010frequency data is promising for crisis periods, but it is difficult to extract relevant business cycle information from them. We present a Bayesian mixed\u2010frequency dynamic factor model with stochastic volatility for measuring GDP growth at high\u2010frequency intervals. Its novelty is an additional state\u2010space block, in which the sparse observations in the mixed\u2010frequency data are augmented to a balanced panel with observed and estimated latent information. The dynamic factors are then estimated conditional on the augmented data. Our model exploits the information in rich datasets of weekly, monthly, and quarterly series, including alternative high\u2010frequency data. GDP is nowcasted timely and accurately during volatile periods.<\/jats:p>","DOI":"10.1002\/jae.3104","type":"journal-article","created":{"date-parts":[[2025,1,21]],"date-time":"2025-01-21T08:46:24Z","timestamp":1737449184000},"page":"270-290","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Tracking Economic Activity With Alternative High\u2010Frequency Data"],"prefix":"10.1002","volume":"40","author":[{"given":"Florian","family":"Eckert","sequence":"first","affiliation":[{"name":"KOF Swiss Economic Institute ETH Zurich  Zurich Switzerland"},{"name":"Statistics, Department I Swiss National Bank (SNB)  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philipp","family":"Kronenberg","sequence":"additional","affiliation":[{"name":"KOF Swiss Economic Institute ETH Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heiner","family":"Mikosch","sequence":"additional","affiliation":[{"name":"KOF Swiss Economic Institute ETH Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefan","family":"Neuwirth","sequence":"additional","affiliation":[{"name":"KOF Swiss Economic Institute ETH Zurich  Zurich Switzerland"},{"name":"Short Term Economic Analyses, Economic Policy Directorate State Secretariat for Economic Affairs (SECO)  Bern Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,1,21]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jeconom.2015.10.010"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jeconom.2023.105634"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1198\/jbes.2009.07205"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/1468-0262.00273"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordhb\/9780195398649.013.0008"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/jae.2306"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/jae.2852"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-economics-080217-053214"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/jae.1174"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/jae.2903"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1162\/rest_a_01213"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.1093\/biomet\/81.3.541"},{"key":"e_1_2_11_14_1","doi-asserted-by":"publisher","DOI":"10.1080\/01621459.2017.1287080"},{"key":"e_1_2_11_15_1","doi-asserted-by":"publisher","DOI":"10.1504\/IJMMNO.2009.030090"},{"key":"e_1_2_11_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jeconom.2023.05.005"},{"key":"e_1_2_11_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/0304-4076(94)90063-9"},{"key":"e_1_2_11_18_1","doi-asserted-by":"crossref","unstructured":"Daniele M.
