Reputation and Perfection in Repeated Common Interest Games

We consider a wide class of repeated common interest games perturbed with one-sided incomplete information: one player (the informed player) might be a commitment type playing the Pareto dominant action. As discounting, which is assumed to be symmetric, and the prior probability of the commitment type go to zero, it is shown that the informed player can be held close to her minmax payoff even when perfection is imposed on the equilibrium.Journal of Economic LiteratureClassification Numbers: C73, D83.     

Sustainability： Corporate Responsibility for the Future Classroom

The machinery, equipment, inventory, and other assets of the 21 st century company without people to work them. Corporations, by leave of the accounting profession, have no real economic value continue to omit the value of human. And yet, there is a growing realization that people represent the largest proportion of corporate productive capacity relative to the current assets and fixed assets shown in corporate financial statements. This paper provides research on the top 50 of the Fortune 500 companies which confirm this material deficiency. There is a need to provide stakeholders with a ＂fair＂ knowledge of the value of corporate human capital to provide a higher standard of transparency and accountability in international financial reporting and to provide the basis for research into the sustainability and potential expansion of growth in the world economy. An appropriate standard for the valuation of human capital will provide the knowledge base for effective and efficient investment in human capital. Effective and efficient investment will be particularly valuable for governments and service industries and for those who wish to promote growth in Europe. Indeed, the Organization for Economic Cooperation and Development （OECD） is questioning the veracity of financial statements which fail to include ＂the most valuable＂ of corporate assets in their financial statements. Recently, the OECD has noted that human capital may be measurable ＂by the output potential of specific competencies＂; ＂the fruits of （corporate） investment＂; the objective measurement of the market ＂rental＂ price of human capital; and lastly, perhaps self-evident when it comes to physical capital, the output potential of corporate investment in their human capital inventory. This paper considers the conditions in the context of literature which reassesses theory and assumptions which have been made on the valuation of human capital. Human capital is a pre-requisite for tangible assets to be productive. The valuation of human capital will trigger the same sort of activity-based analysis of people power as computers brought to cost accounting. The knowledge century analysis of people power will take off when human capital is at last included in the list of assets on the corporate balance sheet.     

Making the Most of Virtual Expertise in Telemedicine and Telehealth Environment

Virtual expertise is a critical component of telehealth projects and it needs to be effectively managed if telehealth is to deliver on its potential. There are many issues within telehealth that relate to the management of knowledge, and we identify and classify these using a range of papers on the topic. We introduce a virtual expertise platform that provides basic building blocks for effect-leveraging of expertise in this domain. The platform includes management directives and goals, a collaborative culture, an appropriate information and communication technology platform, a knowledge management layer, and a tools or application layer that interact to facilitate knowledge sharing, and ultimately improve patient care. We also emphasize how social media tools can be used as part of the tools layer to improve virtual knowledge sharing before and after telehealth events.     

Disappearing private reputations in long-run relationships

For games of public reputation with uncertainty over types and imperfect public monitoring, Cripps et al. [Imperfect monitoring and impermanent reputations, Econometrica 72 (2004) 407-432] showed that an informed player facing short-lived uninformed opponents cannot maintain a permanent reputation for playing a strategy that is not part of an equilibrium of the game without uncertainty over types. This paper extends that result to games in which the uninformed player is long-lived and has private beliefs, so that the informed player's reputation is private. The rate at which reputations disappear is uniform across equilibria and reputations also disappear in sufficiently long discounted finitely repeated games.     

Optimal Complementary Auctions*

This paper considers the situation where two products are sold by the same seller, but to disjoint sets of potential buyers. Externalities may arise from each market outcome to the other. The paper examines the nature of the seller's optimal mechanism, and, for example in the case of positive externalities, it is shown that the allocation decision in either market depends on the highest types in both markets. The optimal mechanism can be implemented by an indirect mechanism that essentially charges winning bidders for the value of their externalities. The analysis is applied to the sale of public sector franchises including exploration and development rights for oil and gas tracts.     

The state of #digitalentrepreneurship: a big data Leximancer analysis of social media activity

This paper examined online sentiment, key themes and patterns evident in social media activity about digital entrepreneurship. It provides a snapshot-in-time, visual-first perspective on social media user-generated-content (UGC) to better understand the topic of digital entrepreneurship. Global data consisting of 31,017 publicly available UGC which used the #digitalentrepreneurship (hashtag) and the keywords ‘digital entrepreneurship’ were collected. A computer assisted qualitative data analysis software (CAQDAS), Leximancer, was used for an automated text-mining analysis. There is positive online sentiment surrounding digital entrepreneurship technology, ecosystem and industry, and one which promotes women transformation of digital entrepreneurship globally. Negative sentiment pointed out that future development and support of youth in digital entrepreneurship is needed. Digital entrepreneurs were identified as needing to focus on strategy, leadership, management, and social media platforms. A comprehensive perspective on the state of digital entrepreneurship in online UGC is provided. Insights into the challenges, issues, changes, success stories and key topics in digital entrepreneurship are highlighted. Future research is encouraged to adopt longitudinal and quantitative approaches, to provide further insights into the evolution of digital entrepreneurship. The paper contributes to the entrepreneurship literature by applying the Social Exchange Theory and the Social Media User Engagement Framework to better understand social media activity around digital entrepreneurship. The findings show that there are real challenges and issues to overcome but there are also changes occurring in digital entrepreneurship and social media users are keen to share and learn from digital entrepreneurship success stories.

     

Reputation with equal discounting in repeated games with strictly conflicting interests

We analyze reputation effects in two-player repeated games of strictly conflicting interests. In such games, player 1 has a commitment action such that a best reply to it gives player 1 the highest individually rational payoff and player 2 the minmax payoff. Players have equal discount factors. With positive probability player 1 is a type who chooses the commitment action after every history. We show that player 1's payoff converges to the maximally feasible payoff when the discount factor converges to one. This contrasts with failures of reputation effects for equal discount factors that have been demonstrated in the literature.     

Developing cross-selling capability in key corporate bank relationships: the case of a Nordic Bank

This research focuses on the challenges in developing the cross-selling capability of a multinational European corporate bank operating in both the business and consumer markets. An extensive qualitative research design was carried out involving 50 interviews with chief financial officers (CFOs) and bank representatives from four European countries, eight workshops, and participant observation. The barriers to cross-selling experienced by the Bank are specifically: a lack of cooperation within organisational levels and units, non-existent information sharing among employees, underdeveloped internal services for cross-selling, resistance to change, and outdated CRM systems are identified as the five major internal challenges that banks have to cope with. Corporate customers however perceive that the five major challenges that inhibit the corporate banks’ ability to provide better services and to properly exploit cross-selling capability are: the lack of cross-asset management, inability to sell cross-asset services, fragmented organisational structure, the lack of sufficient internal marketing and communication, and lack of knowledge sharing. This study identifies ten major challenges—five that deal with the Bank’s internal personnel, and five identified by key corporate customers—that are essential to overcome to better address cross-selling efforts.
