| Abstract: | This paper examines the relationship between patents, appropriability strategies and market for technologies in the English brewing industry before 1850. Previous research has pointed to the apparent oddity that large-scale brewing in this period was characterized both by a self-aware culture of rapid technological innovation, and by a remarkably low propensity to patent. Our study records how brewery innovators pursued a wide variety of highly distinct appropriability strategies, including secrecy, selective revealing, patenting, and open innovation and knowledge-sharing for reputational reasons. All these strategies could co-exist, although some brewery insiders maintained a suspicion of the promoters of patent technologies which faded only in the nineteenth century. Furthermore, we find evidence that sophisticated strategies of selective revealing could support trade in inventions even without the use of the patent system. |

| Abstract: | We investigate women's underrepresentation among holders of commercialized patents: only 5.5% of holders of such patents are female. Using the National Survey of College Graduates 2003, we find only 7% of the gap in patenting rates is accounted for by women's lower probability of holding any science or engineering degree, because women with such a degree are scarcely more likely to patent than women without. Differences among those without a science or engineering degree account for 15%, while 78% is accounted for by differences among those with a science or engineering degree. For the latter group, we find that women's underrepresentation in engineering and in jobs involving development and design explain much of the gap. |

| Abstract: | Intelligently allocating research effort and funds requires deciding whether to build on recent advances or on more established knowledge. When recent advances create superior opportunities for invention, their adoption as research inputs in the invention process promotes technological progress. The gains from pursuing such innovative research paths may, however, be very limited, due to the undeveloped nature of new knowledge, quick obsolescence of fast-improving knowledge, and the vast scope of the existing knowledge base. In this paper, we first develop a new approach to identifying research inputs in invention. Next, we estimate the value of pursuing innovative research paths that are created by the arrival of new research inputs. We identify research inputs based on a natural language analysis of 10 billion word and word sequence patent pairs in 6 million patents granted during 1920-2010. This novel textual analysis empirically reveals which single and general purpose technologies and scientific discoveries have been popular as research inputs in invention. We estimate the value of innovative research by comparing patents that mention these research inputs early against the value of other patents. For this comparison, we develop also a new measure of patent value. The measure distinguishes between citations that reflect the cumulative nature of invention and citations that may merely reflect similarity. |

| Abstract: | This paper is an exploratory study on main features and challenges of the Chinese pharmaceutical market. Dramatic changes in the market are due both to the Government policies, changing consumer habits and behaviour, and to the growing competition at firm level. From a demand side perspective, consumptions of pharmaceutical products are booming thanks to a combined effect of economic growth, aging population, urbanization and health system reforms. Key forces shaping the demand are examined in the chapter, with a specific attention to health care reforms as well as to new habits and confidence of Chinese people towards the Western medicine. In this regard, import and export trends, consumption, and expected evolution of the market are examined. From a supply side perspective, two main trends can be highlighted: the increasing interest of foreign investors, and the effort of Chinese pharmaceutical firms to compete in the national market. To better understand the ongoing changes we look at market characteristics, key players, as well as trends and motivation of inward FDI to China are examined. On the basis of this general picture, the paper focuses on IP related aspects, to understand who are the main actors of patenting trends (foreign vs local firms) and for which kind of products patents are registered (raw materials vs basic products vs drugs). Analyzing patent trends and the role of Chinese vs Western firms, we try to define how China is taking its role and position into the national and – potentially - international pharmaceutical market. |

| Abstract: | This paper analyses the effect of skilled migration on two measures of innovation, patenting and citations of scientific publications, in a panel of 20 European countries. Skilled migrants positively contribute to the knowledge formation in host countries as they add to the pool of skills in destination markets. Moreover, they positively affect natives' productivity, as new ideas are likely to arise through the interaction of diverse cultures and diverse approaches in problem solving. The empirical findings we present support this prediction. Greater diversity in the skilled professions are associated with higher levels of knowledge creation, measured either by the number of patents applied for through the Patent Cooperation Treaty or by the number of citations to published articles. This finding is robust to the use of different proxies for both the explanatory variables and the diversity index in the labour force. Specifically, we first measure diversity with a novel indicator which uses information on the skill level of foreigners’ occupations. We then check our results by following the general literature, which measures skills by looking at the foreigners’ level of education. We show that cultural diversity consistently increases the innovation performance of European Countries. |

| Abstract: | This study surveys the current state of affairs in Poland with regard to the development of knowledge-intensive entrepreneurship (KIE), or new firm creation in industries considered to be science-based or to use research and development (R&D) intensively. We place KIE in Poland in the larger institutional context, outlining the key features of the country’s National Innovation System, and then focus on KIE itself. Our findings are perhaps more optimistic than many previous studies of knowledge-based economy development in Poland. We observe significant progress due to Polish access to the European Union. The frequency with which universities are playing a significant role as partners for firms in the innovation process has increased significantly; moreover, we observe a significant degree of internationalization of innovation-related cooperation. Another optimistic development is that the level of activity of venture capitalists seems to be fairly high in Poland considering the relatively low degree of development of capital markets offering VC investors exit opportunities. Moreover, after almost two decades of decline in the share of R&D spending in GDP, there are signs that this is beginning to rise, and that businesses are beginning to spend more on R&D. While demand-side problems continue to be significant barriers for the development of KIE, due to the relatively low level of education and GDP per capita in the country, the trends here are optimistic, with high rates of economic growth and improvements in the level of education of younger generations. Significant improvement is still needed in the area of intellectual property protection. |

| Abstract: | Many national and international governments establish organizations for applied science research funding. For this, several organizations have defined procedures for identifying relevant projects that based on prioritized technologies. Even for applied science research projects, which combine several technologies it is difficult to identify all corresponding technologies of all research-funding organizations. In this paper, we present an approach to support researchers and to support research-funding planners by classifying applied science research projects according to corresponding technologies of research-funding organizations. In contrast to related work, this problem is solved by considering results from literature concerning the application based technological relationships and by creating a new approach that is based on latent semantic indexing (LSI) as semantic text classification algorithm. Technologies that occur together in the process of creating an application are grouped in classes, semantic textual patterns are identified as representative for each class, and projects are assigned to one of these classes. This enables the assignment of each project to all technologies semantically grouped by use of LSI. This approach is evaluated using the example of defense and security based technological research. This is because the growing importance of this application field leads to an increasing number of research projects and to the appearance of many new technologies. |

| Abstract: | We investigate the imposition of a horizontal technical barrier to trade (HTBT) in a symmetric, cross-hauling duopoly. Tariffs and subsidies are ruled out, but, in the absence of a mutual recognition agreement, it is possible for governments to impose HTBTs, so long as firms apply different technologies. If firms are first movers, this possibility may induce them to avoid technical collaboration, in order to tempt governments into creating national monopolies, except where spillovers and R&D effects are high. This exacerbates the costs of regulatory protection, compared to standard models without R&D or spillovers. |

| Abstract: | To what extent does "false science" impact the rate and direction of scientific change? We examine the impact of more than 1,100 scientific retractions on the citation trajectories of articles that are close neighbors of retracted articles in intellectual space but were published prior to the retraction event. Our results indicate that following retraction and relative to carefully selected controls, related articles experience a lasting five to ten percent decline in the rate at which they are cited. We probe the mechanisms that might underlie these negative spillovers over intellectual space. One view holds that adjacent fields atrophy post-retraction because the shoulders they offer to follow-on researchers have been proven to be shaky or absent. An alternative view holds that scientists avoid the "infected" fields lest their own status suffers through mere association. Two pieces of evidence are consistent with the latter view. First, for-profit citers are much less responsive to the retraction event than are academic citers. Second, the penalty suffered by related articles is much more severe when the associated retracted article includes fraud or misconduct, relative to cases where the retraction occurred because of honest mistakes. |

| Abstract: | In this paper, we analyse the effects of research collaborations on the scientific output of academic institutions, drawing on data from the first official Italian research assessment exercise. We measure the scientific performance of a research unit as the number of publications that received an excellent grade in the evaluation process. Different aspects of scientific collaboration are taken into account, such as the degree of openness of a research team towards other institutions and/or other countries, the frequency of co-authorships, and the average size of a collaborating team. Using econometric models for count data, we find that collaborations are more effective when they imply knowledge exchange resulting from collaboration with external or foreign colleagues, are very frequent, and the collaborating teams have a small size. |

| Abstract: | Several empirical papers have shown that firms belonging to business groups have a higher propensity to engage in R&D. The purpose of the paper is to demonstrate that this higher propensity depends on the ownership share of controlled companies, besides the presence of co-ordination mechanisms. We develop an analytical model and we empirically test the predictions of the model using a dataset of Italian manufacturing firms. From the development of this model we derive three main implications: a) that there is no difference in R&D propensity between stand-alone firms and firms at the bottom of business groups; b) that head and intermediate firms have a higher R&D propensity compared to stand-alone and firms at the bottom of the group; c) that the intensity of R&D depends on the ownership shares in controlled companies. Overall the results of the empirical analysis are in accordance with the implications of the model. |
