We then consider the exponential R&D production function and establish sufficient conditions for per-firm own R&D expenditures to be an increasing function of knowledge spillovers and technological opportunities. Knowledge spillovers and technological possibilities encourage R&D spending if firms’ decisions on R&D investments are strategic complements. We consider two identical firms that, prior to competition in the product market, first decide whether to reveal their R&D efforts to the other firm and second conduct cost-reducing or demand-enhancing R&D and examine the conditions under which full revelation of R&D efforts to rivals yields higher profits. Trigger strategies which require non-cooperative firms to share their R&D inputs will ensure the efficient sharing of R&D efforts. This model has new policy implications about the effects of knowledge spillovers and complementarity in R&D on the incentives to innovate and promote welfare. We present an intellectual property policy that challenges the traditional model of intellectual property as exclusive ownership rights.","PeriodicalId":51485,"journal":{"name":"Economics of Innovation and New Technology","volume":"32 1","pages":"1069 - 1086"},"PeriodicalIF":3.3,"publicationDate":"2022-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45925677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this way, this study contributes to the literature by providing new evidence on the extent of true state dependence in explaining the persistence of outsourcing R&D to a type of contractor. Further, we explicitly distinguish between offshore and onshore outsourcing strategies and study their own- and cross-state dependence. In doing so, we estimate a set of dynamic models of strategy adoption using a panel of Spanish manufacturing firms from 2005 to 2014. The data allow for the distinction between five types of contractors and their domestic or foreign origin in each of them. Our results support the idea that R&D outsourcing with a type of contractor exhibits true-state dependence although moderate, with onshore R&D outsourcing being more state-dependent than its offshore counterpart. Results also indicate the existence of cross-state dependence in both directions.","PeriodicalId":51485,"journal":{"name":"Economics of Innovation and New Technology","volume":"1 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2022-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41328491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, researchers in this field often seek to provide policy recommendations on how to alleviate these failures. However, previous discussions have often been lacking considerations to the risks of political failures, meaning that policies fail to achieve their stated goals in a systematic manner. In response to this gap, this article aims to illustrate the concept of political failure and its relevance for innovation research. This is done by both discussing how political failure can impact innovation policy and by reviewing the prevalence of any discussions of political failure among top-ranked journals on innovation for the period 2010–2019, a total of 7161 articles. The results show that consideration of political failure is scarce, with a small number of papers that have a substantial analysis of political failures. If the awareness of political failures could be increased, this could lead to better policy recommendations with a more nuanced discussion of the risks and limitations of public policy.","PeriodicalId":51485,"journal":{"name":"Economics of Innovation and New Technology","volume":"32 1","pages":"1037 - 1068"},"PeriodicalIF":3.3,"publicationDate":"2022-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49554039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although a less competitive market structure has been commonly known as an indicator of an entry barrier, pieces of past empirical evidence are mixed. Moreover, technological factors, such as R&D intensity, have also been considered. However, no satisfactory empirical analysis has been made, mostly due to the lack of a suitable proxy variable that can reflect the technological environment of a sector. This study addresses this problem by trying a new proxy variable, cycle time of technologies (CTT), and shows, using the US firm data, that firms in a sector with a long CTT tend to enjoy higher profitability and values than others. A long CTT of a sector presents a high entry barrier against any entrant because in such sectors, an existing stock of knowledge tends to be important for a longer period of time, making new innovation continuously rely on old knowledge owned by incumbents and protected by patent rights.","PeriodicalId":51485,"journal":{"name":"Economics of Innovation and New Technology","volume":"32 1","pages":"1019 - 1036"},"PeriodicalIF":3.3,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46032900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We distinguish between prolific inventors, with high numbers of patents registered in their name, and high-quality inventors, with portfolios comprising patents with large numbers of citations. Using patent data for more than 600,000 inventors, we find that star inventors differ from the pool of non-star inventors in terms of gender: while for non-star inventors being a woman constitutes a significant disadvantage, for stars it actually presents a positive association both with quantity and quality of innovative outputs. Moreover, career length constitutes a key premium for female inventors’ productivity, but with smaller magnitudes among stars. The only exception where we observe no gender differences is among inventors with large portfolios (more than five patent families): among them, women do not display any significant gap in the quality of outputs, nor does career length provide a gendered premium.","PeriodicalId":51485,"journal":{"name":"Economics of Innovation and New Technology","volume":"32 1","pages":"1000 - 1018"},"PeriodicalIF":3.3,"publicationDate":"2022-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44803976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The theoretical model builds on the user innovation theory in services and proposes to distinguish between different modes and degrees of user participation that may perform differently.

Results show that not all user engagement led to similar impacts: more active roles versus passive ones have a significant positive relationship with innovation output, but only specific combinations of user orientation and its intensity matter. Besides, no direct significant impacts from user orientation on productivity were found. As a managerial implication, service companies may approach users as co-innovation partners oriented to service quality and customer satisfaction rather than oriented to increase business efficiency.","PeriodicalId":51485,"journal":{"name":"Economics of Innovation and New Technology","volume":"32 1","pages":"953 - 976"},"PeriodicalIF":3.3,"publicationDate":"2022-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45084120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study discusses a detailed analysis of theoretical predictions and empirical outcomes, based on the regulation–innovation–trade nexus, to assess the specific channels through which such effects might operate. Based on German and East European cross-sectional data at the firm level, results show that an eco-innovation that a regulation induces can generate either a positive effect or a detrimental effect on exporting propensity.
