The conventional QR standard errors can seriously underestimate the uncertainty of estimators and, therefore, overestimate the significance of effects, when outcomes are serially correlated. Thus, we propose a clustered covariance matrix (CCM) estimator to solve this problem. The CCM estimator is an extension of the heteroskedasticity and autocorrelation consistent covariance matrix estimator for QR models with fixed effects. The autocovariance element in the CCM estimator can be substantially biased, due to the incidental parameter problem. Thus, we develop a bias\u2010correction method for the CCM estimator. We derive an optimal bandwidth formula that minimizes the asymptotic mean squared errors, and propose a data\u2010driven bandwidth selection rule. We also propose two cluster robust tests, and establish their asymptotic properties. We then illustrate the practical usefulness of the proposed methods using an empirical application.<\/jats:p>","DOI":"10.3982\/qe802","type":"journal-article","created":{"date-parts":[[2020,5,5]],"date-time":"2020-05-05T07:43:26Z","timestamp":1588664606000},"page":"579-608","source":"Crossref","is-referenced-by-count":11,"title":["Cluster robust covariance matrix estimation in panel quantile regression with individual fixed effects"],"prefix":"10.3982","volume":"11","author":[{"given":"Jungmo","family":"Yoon","sequence":"first","affiliation":[{"name":"College of Economics and Finance, Hanyang University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio F.","family":"Galvao","sequence":"additional","affiliation":[{"name":"Department of Economics, University of Arizona"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2359","published-online":{"date-parts":[[2020]]},"reference":[{"key":"quan200077-bib-0001","doi-asserted-by":"crossref","first-page":"379","DOI":"10.1198\/073500107000000269","volume":"26","author":"Abrevaya","year":"2008","journal-title":"Journal of Business and Economic Statistics"},{"issue":"3","key":"quan200077-bib-0002","doi-asserted-by":"crossref","first-page":"817","DOI":"10.2307\/2938229","volume":"59","author":"Andrews","year":"1991","journal-title":"Econometrica"},{"key":"quan200077-bib-0003","doi-asserted-by":"crossref","first-page":"431","DOI":"10.1111\/j.1468-0084.1987.mp49004006.x","volume":"49","author":"Arellano","year":"1987","journal-title":"Oxford Bulletin of Economics and Statistics"},{"key":"quan200077-bib-0004","doi-asserted-by":"crossref","first-page":"61","DOI":"10.1111\/ectj.12062","volume":"19","author":"Arellano","year":"2016","journal-title":"Econometrics Journal"},{"key":"quan200077-bib-0005","doi-asserted-by":"crossref","first-page":"249","DOI":"10.1162\/003355304772839588","volume":"119","author":"Bertrand","year":"2004","journal-title":"Quarterly Journal of Economics"},{"issue":"3","key":"quan200077-bib-0006","doi-asserted-by":"crossref","first-page":"647","DOI":"10.1214\/aos\/1176345863","volume":"10","author":"Bickel","year":"1982","journal-title":"The Annals of Statistics"},{"key":"quan200077-bib-0007","doi-asserted-by":"crossref","first-page":"107","DOI":"10.1214\/154957805100000104","volume":"2","author":"Bradley","year":"2005","journal-title":"Probability Surveys"},{"key":"quan200077-bib-0008","doi-asserted-by":"crossref","first-page":"317","DOI":"10.3368\/jhr.50.2.317","volume":"50","author":"Cameron","year":"2015","journal-title":"Journal of Human Resources"},{"key":"quan200077-bib-0009","doi-asserted-by":"crossref","first-page":"368","DOI":"10.1111\/j.1368-423X.2011.00349.x","volume":"14","author":"Canay","year":"2011","journal-title":"Econometrics Journal"},{"key":"quan200077-bib-0010","series-title":"Lect.
