We propose a method for tracking patterns of exploration and exploitation in patenting behaviour in the US for the period since 1920. Our exploration measure is constructed from the text of patents and involves the use of Bayesian Surprise to measure how different current patent-based innovations are from existing portfolios. Our results indicate that there are distinct life-cycle patterns to firm and inventor exploration. Furthermore, exploration activity is more geographically concentrated than general patenting, but this concentration is centred outside the main hubs of patenting.","PeriodicalId":346559,"journal":{"name":"Innovation Measurement & Indicators eJournal","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122310057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This categorization corresponds to the two routes of technology evolution: either consolidating or destabilizing past achievements. However, the combinational view suggests that a technology is a recombination of existing components, and hence it may consolidate some of its prior arts while destabilizing others. Therefore, we propose a dual technology can be simultaneously destabilizing and consolidating. To identify dual technologies, we develop the destabilization index (D) and the consolidation index (C) using patent citation networks. To validate the proposed indexes, we first select representative US patent examples to illustrate the face validity by showing how D and C indexes capture the dual characteristics. Secondly, we assess convergent and discriminant validity by examining the correlations between D and C indexes and other innovation measures. Finally, we evaluate nomological validity by studying the antecedents and the predictive power of the dual characteristics using 2.6 million patents from USPTO's dataset from 1976 to 2006. Regression results show that theory-driven factors such as patent novelty and government interest are associated with D and C indexes as expected. We also find that high D and C indexes are positively associated with patent value as perceived by its owner, and entity size moderates the effects of D and C indexes on patent value differently.","PeriodicalId":346559,"journal":{"name":"Innovation Measurement & Indicators eJournal","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126773483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The economic complexity approach is an alternative understanding of how economic sophistication can affect well-being. Moreover, there is increasing literature using traditional Data Envelopment Analysis (DEA) models to measure the transformation of wealth into human development. However, we did not find studies comparing more advanced models, such as Slack Based Models (SBM), and which considers the economic sophistication as an input to generate human development. To fill this gap, the aim of this article is to compare traditional and SBM-DEA models, measuring the countries' efficiency in converting economic complexity into human development. We analyzed 50 countries through Data Envelopment Analysis (DEA) in 2013, comparing Constant and Variable returns of scale traditional and Slack Based models. We also proposed the Composite Index of Human Development and Economic Complexity (CIHD-EC). Our findings show that the traditional variable return of scale model tends to overestimate efficient countries. It occurs especially in developed and rich economies. In contrast, the slack-based model provides a better understanding of the problem under analysis. Finally, our CIHD-EC shows that only Singapore is efficient to transform economic complexity into human development around the world.","PeriodicalId":346559,"journal":{"name":"Innovation Measurement & Indicators eJournal","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121665267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, science curiosity is of great interest to scholars across the social sciences. However, measuring science curiosity via the science curiosity scale (SCS; Kahan et al., 2017) is highly time intensive; potentially impeding its widespread usage. In this paper, we present two new methods for reducing SCS administration time. One method presents respondents with a randomly selected subset of items (the \"Random Subset Method; RS\"). The other asks all respondents a core set of just four items (the \"Reduced-Form Method; RF\"). In three nationally representative surveys of U.S. adults, we assess the construct, convergent, and predictive validity of these alternatives. Across studies, the RS and RF versions of the SCS appear to be well validated. We conclude by discussing how researchers can apply these insights into their own research.","PeriodicalId":346559,"journal":{"name":"Innovation Measurement & Indicators eJournal","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133681805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","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 Song Explorer 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 considers what kind of recombinations are associated with high impact. 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 Every Noise at Once, that provides a map of over 1,800 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 then used as explanatory variables in a regression that seeks to explain impact (YouTube views per day since the songs' video release), while controlling for other determinants of song impact, 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 impact.","PeriodicalId":346559,"journal":{"name":"Innovation Measurement & Indicators eJournal","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127210168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
