Insights from the Hearing Aid IndustryKirkegaard, Matilde Fogh (Frederiksberg, 2018)[Flere oplysninger][Færre oplysninger]
Resume: Through an investigation of individual decision-making behavior and the impact it has on the perceived value of innovation, this thesis offers novel perspectives on key strategic management issues. We demonstrate how the value of innovation, when identified as a subjectively realized value by the consumer, specifically, perceived product benefits, can help identify the role of individual decision-making as well as behavioral factors guiding value creation of innovation. In the intersection between behavioral science and strategic management of innovation, these insights take the perspective of both the firm-side and demand-side of a value chain by identifying innovation performance as value created at the levels of the manufacturer, the salesperson and the consumer. Hence, this thesis contributes to the strategic management literature on innovation and value creation by answering the following research question: To what extent do decision-making heuristics at the individual level affect value creation at the firm-side and the demand-side of the value chain, and what management practices can facilitate decision-making for improved value creation? By attending to both the manufacturer and product market, the three papers constituting this thesis identify opportunities to augment value creation by exploring whether systematic behavioral bounds determine the likelihood of innovations to fulfill firms’ expectations for innovation performance. The thesis introduces specific behavioral strategies for the decisionmaking context that are critical to realizing business outcomes and identifying the key observations and challenges that managers face that affect value creation along dimensions of firm activities.

Tie Formation in the Sector of Service Intermediaries in ShippingNowińska, Agnieszka (Frederiksberg, 2018)[Flere oplysninger][Færre oplysninger]
Resume: The aim of the dissertation is to shed light on the complex determinants of tie formation. Extant research has linked similarity and dissimilarity (respectively homophily and heterophily) and different proximities types to the likelihood of tie formation in a linear way. However, there are significant differences in how ties form depending on 1) tie characteristics (formal vs informal), 2) group belonging (female vs. male), 3) types of proximities involved and their interplay, 4) temporal dynamics. Therefore, to fill gaps in the literature, this dissertation addresses the question on how the likelihood of tie formation is correlated with 1) the interplay of geographical and industry space proximities in formal inter-firm ties over time, 2) organizational and geographical proximity in case of formal employer-employee ties after organizational failure 3) gender homophily for females and males in case of informal employee-employee ties. I use the empirical setting of service intermediaries: shipbrokers and bunker traders, in the international shipping industry. My methodological approach includes mixed (qualitative and quantitative) methods and a quasi-natural experiment. The dissertation comprises three empirical studies that address the research questions outlined. The dissertation’s main contribution lies in demonstrating the complexity of tie determinants. The first chapter explains the premises, gap, empirical setting, methods and contribution of this dissertation. The following chapter (Chapter 2) analyses the role and interplay of geographical proximity and buyers’ types (such as competitors) for the tie formation in formal inter-firm transactions in shipbroking. I find that the effect of geographical proximity does not significantly correlate with tie formation between the focal shipbroker firm and the buyers, it however positively moderates the lower likelihood of dealing with competitors. This finding is explained with co-opetition (simultaneous pursuit of cooperation and competition) in local clusters of service firms. Chapter 3 studies the unexpected and exogenous organizational failure following a fraud and its effects on the status change of displaced employees transitioning into new employment. While there is no generalized stigma in the studied setting, employees organizationally and geographically proximate to the pivot of the failure are more prone to a status loss in guise of lower level jobs or jobs at lower status firms. The mechanisms that explains such a systematic pattern of status loss is blame. Similar to stigma by its spillover effects, it operates however less spread therefore, in contrast to stigma’s “wide brush”, the blame taints with a “pointed brush”. Further, Chapter 4 analyses the differential effects of gender homophily for females and males on the likelihood of co-mobility: while male dyads are more likely to be co-mobile, female dyads are less likely to be co-mobile. By further investigating possible underlying mechanisms, the chapter finds a strong support for labor market discrimination driving the results for female dyads.

Resume: The first essay shows that corporate bond issuers derive value from bond underwriter relationship capital. A strong underwriter relationship enables the underwriter to credibly certify the issuer on the bond market which is fundamental for firms when issuing new debt and refinancing maturing debt. In order to empirically verify this certification hypothesis we study corporate bond issuing firms' underwriter relations and analyze their value for the issuing firm. The second essay provides a detailed investigation of the implications of creditors' use of credit default swaps (CDSs) for the debt financing of related firms. CDSs are financial derivatives that protect the buyer against default of a given reference firm. The availability of CDS contracts has in general been outlined to improve bank lending by reducing financial frictions on the supply side of credit. Using unique and comprehensive CDS and credit registry data from Deutsche Bundesbank I explicitly study the CDS holdings of banks with a credit relationship to the reference firm and analyze the role of the variation in creditors use of CDSs for the borrower's debt financing. As outlined in the data creditors typically hold multiple CDSs written on the same firm and are often also net sellers of CDS contracts written on their own borrowers. The third essay investigates whether unconventional monetary interventions by central banks can stimulate corporate investment and, thus, afiect the real economy. Specifically, we address this question by analyzing ECB's three-year Longer-term Refinancing Operations (LTROs) as of 2011-2012. The LTROs were large liquidity injections that were implemented to support the real economic recovery after the European Sovereign Debt Crisis and provided cheap funding to Eurozone banks. For the empirical investigation of the impact of such liquidity interventions, we make use of comprehensive data on banks' use of the LTRO funds and Eurozone non-financial corporations' investment policies around the LTRO implementation.

Resume: The central formula in asset pricing relates the price of an Arrow-Debreu security to an investor's preferences and beliefs: Price of an Arrow-Debreu security = Preferences Beliefs. We observe the prices of Arrow-Debreu securities in the option markets. But we do not directly observe the extent to which these prices are driven by preferences or beliefs. Decomposing and investigating preferences and beliefs is essential for understanding asset prices, and it is therefore the focus of this thesis. In chapter one, my co-authors and I develop a model in which we can disentangle the contribution in asset prices which is driven by preferences and beliefs. In chapter two, my co-author and I estimate investor beliefs and study how these beliefs vary over time. In chapter three, I estimate investor preferences and study how they co-vary with investor beliefs. URI: http://hdl.handle.net/10398/9653 Filer i denne post: 1

An Empirical StudyBentsen, Stine Evald (Frederiksberg, 2018)[Flere oplysninger][Færre oplysninger]
Resume: Based on the assumption that language is more than a neutral means of communication, and our mother tongue is strongly anchored in our body, mind and culture, this project investigates the comprehension of English texts by native and non-native speakers of English from England, China, Japan and Russia. This project takes its starting point in Durst-Andersen’s understanding of language as a system of signs which highlights the fundamental role of the lexicon of our mother tongue in anchoring words not only in our mind but also in our body through its process of acquisition, establishing at the same time the intrinsic link between language and culture. For this project, I view comprehension as an integrated part of the communication process. This understanding shows how speaker and hearer are able to meet in communication, first through the common voice of grammar, which serves as the end point of the speaker’s role in communication and marks the starting point for the hearer’s part in communication. This is the physical point of contact. And second, through the process of anchoring, where the hearer backtracks the journey made by the speaker to recreate in her own mind what lied before. This is the mental point of contact. Thus, comprehension is layered and the full understanding of an utterance involves comprehending both layers, i.e. reaching both meeting points. Focusing specifically on the comprehension of the disjunctive particle ‘or’ and the comprehension of directives, I investigate (1) how the same English texts are comprehended by native speakers of English from England and non-native speakers of English from Japan, China and Russian, respectively, (2) what the differences and/or similarities are, and (3) what these differences and/or similarities tell us about comprehension in a foreign language compared to a mother tongue. This was investigated through a qualitative analysis of data collected through the GEBCom Reception Test, designed specifically for this purpose. The test consists of 36 short texts evolving around ten different elements of interest. Following each text is a series of questions with multiplechoice answers designed to elicit the participants’ comprehension of the text. The participants were 90 university students from England, Japan, China and Russia. Findings from the comprehension of ‘or’ showed how all native speakers made an inclusive interpretation of the disjunctive particle, i.e. as meaning ‘both… and’, indicating that for native speakers of English this seems to be a grammatical distinction. Though all three groups of non-native speakers shared the inclusive reading, a rather large portion of especially the Chinese and Japanese speakers of English differed from this understanding and comprehended ‘or’ in this text as meaning ‘either… or’. The findings from the comprehension of directives also showed similarities in comprehension between native speakers and non-native speakers but highlighted many differences as well. The analysis of the native speakers’ comprehension showed how the specific communication process of English seemed to influence their comprehension of directives, affecting their overall understanding both in terms of how polite they perceived the text, what intention they ascribed to it and which course of action they would take after having read it. Common for the non-native speakers’ comprehension across texts was the fact that even though they seemed to form the same basic understanding, i.e. reach the same physical point of contact as the native speakers, the journey they made from here was different, meaning they ended up forming a different full understanding of the texts, be this in terms of their evaluation of politeness, their interpretation of the intention behind the text or the course of action they would take subsequently. Taken together the findings from this project showed that the process of comprehension in ELF is complex, suggesting that it may not always be possible or even relevant to conceptualise transfer as a direct transfer from mother tongue to foreign language, but rather as a subtle influence with possible profound influence for the overall understanding.
