Trademarks, Firm Longevity and IPO Underpricing

We examine the role of trademarks in firm longevity and IPO underpricing. We borrow arguments from asymmetric information theory and juxtapose alternative explanations to uncover which approach best describes the underpricing phenomenon with the aid of trademarks relationship to firm longevity. We further argue that TMs that are associated with physical products are more likely to reduce information asymmetries than TMs associated with services. Therefore, we posit that TM activity by firms in the service industries is more likely to increase underpricing while in the case of the manufacturing firm’s TM activity is less (or not) likely to result to increased underpricing. We collect 2,275 US IPOs from 1997-2016 and we find that on average the presence of trademarks in a firm’s portfolio increases underpricing. We link our results with the extant literature and provide evidence which supports that higher trademark activity is associated with firm longevity and signaling quality through IPO underpricing

Mobility of highly skilled individuals and local innovation activity

Mobilization of valuable resources, especially of talented individuals, figures prominently in firms’ strategies and policy agendas. Thus far, there is a dearth of empirical evidence in the field. The contribution of this paper is two-pronged: first, to perform an integral evaluation of the different factors that shape the mobility of patent inventors -a specific class of highly skilled individuals, who are deeply involved in the production of innovation and are important vehicle of technological knowledge circulation- and second, to assess the effects of their mobility on local innovation activity. Employing detailed patent data to track their moves, we use a gravity model to examine whether geographic, technological, and cultural proximities between countries, among other factors, shape the flows of these talented individuals. Using the same framework of analysis, we also examine the mobility of non-inventor migrants. Our results show that although geographic distance still plays a role, inventor migrants are less geographically confined than non-inventor migrants. Countries’ technology similarity is the main driver of inventor moves, whereas cultural -linguistic and religion- proximity matters more for non-inventor migrants. Finally, the knowledge and skills that move with the inventors have a positive effect on the production of new knowledge in the host country

University archives: the research road travelled and the one ahead

Purpose University archives (UA) are the bridge between the past and the present and serve as a beacon for highlighting the contribution of academic institutions to society. Although the UA topic was introduced and formalized in the 1950s, the scientific research interest has increased significantly in the past two decades. This paper aims to provide insights into the UA research topic during the previous 15 years. Design/methodology/approach The combination of two well-established methods for performing literature review was deployed, aiming to identify, select and assess the research documents. Based on the selection criteria, 49 documents presenting research efforts around the UA topic were finally examined from the Scopus citation index. The selected studies have been classified into three main topics: strategic management of UA and the derived challenges, the educational contribution of UA and the strategic information systems for UA. Findings Some of the main findings are the lack of well-defined administrative policies, the low level of awareness and archival consciousness within the universities, the inadequacy of university archivists’ educational and training background, the need to use UA for building relationships with alumni and society, and finally, the need for metadata standardization by the UA management systems. Originality/value As a literature review around UA has not been conducted before, the reader will gain insights into the methods and research designs that other scholars had already applied to designate useful findings and results. </jats:sec

Content Management Systems Performance and Compliance Assessment Based on a Data-Driven Search Engine Optimization Methodology

While digitalization of cultural organizations is in full swing and growth, it is common knowledge that websites can be used as a beacon to expand the awareness and consideration of their services on the Web. Nevertheless, recent research results indicate the managerial difficulties in deploying strategies for expanding the discoverability, visibility, and accessibility of these websites. In this paper, a three-stage data-driven Search Engine Optimization schema is proposed to assess the performance of Libraries, Archives, and Museums websites (LAMs), thus helping administrators expand their discoverability, visibility, and accessibility within the Web realm. To do so, the authors examine the performance of 341 related websites from all over the world based on three different factors, Content Curation, Speed, and Security. In the first stage, a statistically reliable and consistent assessment schema for evaluating the SEO performance of LAMs websites through the integration of more than 30 variables is presented. Subsequently, the second stage involves a descriptive data summarization for initial performance estimations of the examined websites in each factor is taking place. In the third stage, predictive regression models are developed to understand and compare the SEO performance of three different Content Management Systems, namely the Drupal, WordPress, and custom approaches, that LAMs websites have adopted. The results of this study constitute a solid stepping-stone both for practitioners and researchers to adopt and improve such methods that focus on end-users and boost organizational structures and culture that relied on data-driven approaches for expanding the visibility of LAMs services.</jats:p
