To address this objective, this article applies a fractional response model. The results allow us to confirm that the impact of the pandemic crisis depends on firm structure and behaviour reflected by variables such as firm size, age, export intensity, market channel as well as on the geographic location of firms. This suggests the need for the development of innovative regional clusters and calls for managers and policymakers to consider the heterogeneity of wineries and dissimilar effects of contingency measures at the municipal level during an exogenous shock.<\/jats:p>","DOI":"10.36253\/wep-13917","type":"journal-article","created":{"date-parts":[[2024,1,11]],"date-time":"2024-01-11T17:21:25Z","timestamp":1704993685000},"page":"43-54","source":"Crossref","is-referenced-by-count":0,"title":["Fractional responses with spatial dependence of Portuguese wineries\u2019 domestic market sales to an exogenous shock (Covid-19)"],"prefix":"10.36253","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7533-7412","authenticated-orcid":false,"given":"Samuel","family":"Faria","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3564-7771","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Rebelo","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2019-3535","authenticated-orcid":false,"given":"Alexandre","family":"Guedes","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9680-0114","authenticated-orcid":false,"given":"Sofia","family":"Gouveia","sequence":"additional","affiliation":[]}],"member":"21822","published-online":{"date-parts":[[2023,12,31]]},"reference":[{"key":"17903","doi-asserted-by":"crossref","unstructured":"J.-M.
