Novel advancements in the Markov chain stock model: analysis and inference

In this paper we propose further advancements in the Markov chain stock model. First, we provide a formula for the second order moment of the fundamental price process with transversality conditions that avoid the presence of speculative bubbles. Second, we assume that the process of the dividend growth is governed by a finite state discrete time Markov chain and, under this hypothesis, we are able to compute the moments of the price process. We impose assumptions on the dividend growth process that guarantee finiteness of price and risk and the fulfilment of the transversality conditions. Subsequently, we develop non parametric statistical techniques for the inferential analysis of the model. We propose estimators of price, risk and forecasted prices and for each estimator we demonstrate that they are strongly consistent and that properly centralized and normalized they converge in distribution to normal random variables, then we give also the interval estimators. An application that demonstrate the practical implementation of methods and results to real dividend data concludes the paper.     

Zero lower bound,ECB interest rate policy and the financial crisis

We explore whether the ECB’s interest rate setting behaviour changed during the financial crisis by estimating reaction functions over the period 1999–2010, allowing for a smooth transition from one set of parameters to another. The estimates show a swift change in the months following the collapse of Lehman brothers. The ECB appears to have cut rates more aggressively than expected solely on the basis of the worsening of macroeconomic conditions, consistent with the theoretical literature on optimal monetary policy in the vicinity of the zero bound.     

The performance implications of outsourcing customer support to service providers in emerging versus established economies

Recent discussions in the business press query the contribution of customer-support outsourcing to firm performance. Despite the controversy surrounding its performance implications, customer-support outsourcing is still on the rise, especially to emerging markets. Against this backdrop, we study under which conditions customer-support outsourcing to providers from emerging versus established economies is more versus less successful. Our performance measure is the stock-market reaction around the outsourcing announcement date. While the stock market reacts, on average, more favorably when customer-support is outsourced to providers located in emerging markets as opposed to established economies, approximately 50% of the outsourcing firms in our sample experience negative abnormal returns. We find that the shareholder-value implications of customer-support outsourcing to emerging versus established economies are contingent on the nature of the customer support that is being outsourced and on the nature of the outsourcing firm. Customer-support outsourcing to emerging markets is less beneficial for services that are characterized by personal customer contact and high knowledge embeddedness than for customer-support services that involve impersonal customer contact and are low on knowledge embeddedness. Firms higher in marketing resource intensity and larger firms benefit more from outsourcing customer-support services to emerging markets than firms lower in marketing resource intensity and smaller firms.     

Resources and governance in “base of the pyramid”-partnerships: Assessing collaborations between businesses and non-business actors

Identifying, building, and maintaining partnerships with non-business actors are crucial challenges for multinational companies (MNCs) when implementing Base of the Pyramid (BoP) projects. Using a multiple-case study we analyze such partnerships through the lens of the relational view, focusing on resources generating inter-organizational value and on mechanisms for governing the partnerships. The cross-case analysis suggests that proficiency in identifying appropriate partners featuring non-tangible synergy-sensitive resources is vital for BoP ventures. MNCs compensate for their lack of local knowledge, contacts, and legitimacy by recruiting non-business actors for this consultancy and brokering function. Once a suitable network of partners has been identified, these resources need to be explored and exploited by developing personal relationships, communication routines, common goals, and partner-specific capacity building. Synergy-sensitive resources facilitate performance and long-term maintenance of BoP partnerships by establishing well-adapted and well-informed management practice and by creating a lock-in that works as an informal self-enforcing governance mechanism.     

Are rigor and transparency enough? Review and future directions for case studies in technology and innovation Management

It is crucial to assess how technology and innovation management (TIM) scholars use case-based research. Our study provides a theoretical systematic review of qualitative case-based articles published in 31 TIM journals from 2013 to 2018. Our analysis of 311 articles uncovers patterns regarding rigor (including case justification and selection), transparency (including data collection and analytical methods), and paradigmatic consistency and pluralism. Our findings show some evidence of emerging pluralism in how TIM researchers perform qualitative case studies, but also highlight some worrying trends: paradigmatic inconsistencies, lack of transparency, and over-reliance on specific approaches, all of which affect the value of case study research. We provide methodological guidelines for improving the use of qualitative case research in TIM.     

Appropriability mechanisms for manufacturing and service firms: the contingencies of openness and knowledge intensity

Conventional wisdom argues that appropriating returns from innovation requires protection mechanisms. However, there will be limits to the effectiveness of formal and informal appropriability mechanisms for innovation performance. Their effectiveness will be contingent on the nature of the knowledge that firms are trying to protect and the openness of their innovation strategy (sharing knowledge while attempting to protect knowledge is known as the ‘paradox of openness’). Do these boundary conditions apply to both manufacturing and service firms equally though? Analyzing data from the UK Community Innovation Survey, this study provides evidence for a continuum – from discrete product manufacturing firms, whose products rely heavily on codified, explicit knowledge and for which formal methods are strongly associated with innovation performance, to knowledge-intensive service firms, which tend to rely more on complex tacit knowledge and for which innovation is linked to informal, not formal, appropriability. The findings show that the paradox of openness is a limited problem for service firms. The benefits of collaboration for innovation performance outweigh any reduction in the effectiveness of appropriability. For manufacturers, the benefits of collaboration disappear with high formal appropriability, and thus, discrete product manufacturers, contrary to conventional wisdom, may find it beneficial to reduce collaboration breadth and invest in informal appropriability mechanisms. Knowledge-intensive servitized manufacturers find formal methods effective but only with no or minimal collaboration.     

Profitability Development and Resource Reallocation: The Case of Sugar Beet Farming in Germany

Following the 2006 reform of the European Union sugar market, and in anticipation of the quota abolition, a reallocation of sugar production has occurred. Using a Lowe quantity index, we evaluate the productivity and profitability of sugar beet farming in Germany from 2004 to 2013. The results show that an increase in total factor productivity partly compensated for losses in terms of trade. Moreover, the contribution of production reallocation to sector productivity growth varied across regions with distinct ownership structures of sugar processing companies. These findings have implications for policy and industry, as it transitions to a liberalised market.     

The influence of feedback and awareness of consequences on the development of corporate sustainability action over time

The current level of corporate sustainability is insufficient for overcoming pressing environmental and social issues. Research is therefore needed about processes that lead to increased corporate action that fosters sustainable development. This study investigates the influence of feedback and corporate awareness of consequences on the development of corporate sustainability action over time. It uses action regulation theory to quantitatively analyse data of 59 large German companies measured at two points in time. The results reveal a positive temporal development of corporate sustainability action, and awareness of consequences positively mediates the relationship between corporate sustainability actions in two different time periods. Feedback acts as a moderator between the positive effect of corporate sustainability action in the first period on corporate awareness of consequences in the second period. Based on these findings, recommendations for organisations include the importance of seeking and processing feedback.
