Our paper aims to investigate the determinants of network formations between Brazilian regions between 2000 and 2011. We use the patent database from the National Institute of Intellectual Property (INPI) to create a network of inter-regional co-patenting in Brazil. The main results indicate that: (1) geography still plays a fundamental role in forming networks; (2) the network and its subcomponents are spatially concentrated; (3) there is an unequal geographical agglomeration pattern in the Brazilian invention system and (4) technological and relational proximity are important factors in determining new connections.</p></div>","PeriodicalId":100389,"journal":{"name":"EconomiA","volume":"22 1","pages":"Pages 71-83"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.econ.2020.11.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81492486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper I explore this question through an analysis of data from the <em>Song Explorer</em> podcast, where composers describe how they created a specific song. I mine their accounts to classify their processes into seven different, but not mutually exclusive, theories of the creative process. The result of this exercise suggests that the recombination of existing songs is a major process for the creation of new successful songs. The second step uses the average number of daily <em>YouTube</em> views per day since the songs’ video release as a measure of the song’s impact, and tests how this impact is associated with the seven theories. For each song in the sample, I have one or more other songs which were explicitly indicated as an influence or inspiration. I use the music genre classification system <em>Every Noise at Once,</em> that provides a map of over 1800 genres and millions of songs to create a set of descriptive statistics of the similarity of each song to their inspiration-songs. These statistics are used to measure different recombination strategies in a regression that seeks to explain songs’ relative success, while controlling for other determinants, such as the artists’ established level of popularity. The results confirm the optimal differentiation hypothesis that the simultaneous presence of conventionality together with novelty, and not just one or the other, is a major determinant of creativity and success.</p></div>","PeriodicalId":100389,"journal":{"name":"EconomiA","volume":"22 1","pages":"Pages 38-52"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.econ.2021.02.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"137421920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis is based on panel data for the 2010–2013 period and approximately 305,000 south Brazilian firms. We explore different times of entry into export market to use a fixed effects specification. Our results show that on average there are no learning-by-exporting effects on average wages for firms in our sample. However, when interacting firms export status with its human capital level, the effects turn out to be statistically significant. Finally, results suggest that the interaction between export gains and firms’ human capital level is driven by firms exporting to developing countries. We explain this last result by the following mechanism. Low wage countries mainly produce low quality goods. Therefore, firms employing high skilled labor can differentiate their products and consequently escape from intense competition from these countries in the foreign market, obtaining higher export gains.</p></div>","PeriodicalId":100389,"journal":{"name":"EconomiA","volume":"21 3","pages":"Pages 365-376"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.econ.2020.05.003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84289003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
