Explicit Representation of the Minimal Variance Portfolio in Markets Driven by Lévy Processes

In a market driven by a Lévy martingale, we consider a claim ξ. We study the problem of minimal variance hedging and we give an explicit formula for the minimal variance portfolio in terms of Malliavin derivatives. We discuss two types of stochastic (Malliavin) derivatives for ξ: one based on the chaos expansion in terms of iterated integrals with respect to the power jump processes and one based on the chaos expansion in terms of iterated integrals with respect to the Wiener process and the Poisson random measure components. We study the relation between these two expansions, the corresponding two derivatives, and the corresponding versions of the Clark-Haussmann-Ocone theorem.     

Trends in Advertising Research: A Longitudinal Analysis of Leading Advertising,Marketing, and Communication Journals, 1980 to 2010

This study provides a longitudinal content analysis of advertising research articles in 17 top-tier advertising, marketing, and communication journals published over the past 30 years (1980–2010, n = 926). The study's purpose is to shed light on the direction and progression of advertising as an academic field by updating and extending Yale and Gilly's (1988) study of advertising research trends. Nine content characteristics of the journal articles were examined: (1) theory presence (theory driven versus not theory driven), (2) names, types (theory versus theoretical framework/model versus construct), and originating disciplines of theory, (3) topic areas, (4) media of interest, (5) research approaches (empirical versus nonempirical and quantitative versus qualitative versus mixed), (6) methods, (7) types of effects, (8) units of analysis, and (9) research implications. Changes in the content characteristics of journal articles were found across the 30 years analyzed in five-year intervals. Implications for the field, scholars, and advertising practitioners are discussed.     

Banking the bear: Financial marketization in Russia

The world's view of the former Soviet Union since its disintegration in late 1991 has been shaped largely by media coverage of Russia's troubled political landscape: attempted coups, tanks on Red Square, inflammatory nationalistic rhetoric of Vladimir Zhirinovsky, and general uncertainty. To the outsider, chaos seems to reign. Yet economic progress has been made in the last three years. Behind this chaotic democracy lie strong roots for enormous growth in its fledgling financial markets. By adopting Western standards, Russia is cultivating market driven access to capital, the key to any serious economic transformation.     

Values,personality traits,and packaging-free shopping: A mixed-method approach

This research examines packaging-free shopping, which contributes to reducing the negative impact of plastic packaging on the environment, and its’ relationship with green consumption values, value consciousness, and psychological traits. A mixed-methods approach is adopted with quantitative followed by qualitative research. Study 1 recruits 240 respondents from social media and the lead author's university website to examine different factors that increase consumers’ likelihood of packaging-free shopping. Study 2 recruits packaging-free shoppers from Facebook Pages, explores these findings and provides further insights. Study 1 finds that consumers are driven more by green consumer values than by value consciousness, and consumers who are more conscientious are more likely to do packaging-free shopping. Study 2 supports this by finding that green consumer values drive packaging-free shopping, but this in only one part of their green efforts. The research contributes by illustrating the importance of conscientiousness specifically in the domain of packaging-free shopping and that these packaging-free shoppers are not driven in terms of value for money but by addressing their green consumer values. We recommend that packaging-free retailers and policy makers utilize promotional efforts to communicate how packaging-free shopping provides a balance with consumers’ green values for these shoppers, how it fits in with their other green efforts, and how these shopping efforts are making a difference in helping the environment.     

Scientific Paradigms,Entrepreneurial Opportunities and Cycles in Economic Growth

In this paper I present a model of economic growth that combines insights from endogenous growth theory, the field of entrepreneurship research and the philosophy and economics of science. The model is built on three relatively standard assumptions and a Kuhnian approach to scientific knowledge accumulation. I assume that innovation generates economic growth, that opportunity driven entrepreneurship is an important source of innovation, that entrepreneurial opportunities increasingly arise out of scientific knowledge creation and that science follows Kuhnian paradigm shifting dynamics. The model then generates opportunity driven cycles in entrepreneurial activity that in turn cause waves of innovation and cycles in economic growth. This result is highly relevant and fills a gap in all three literatures as ‚traditional’ endogenous growth models typically generate constant growth rates in the steady state, entrepreneurship research keeps the origin of entrepreneurial opportunity exogenous and the literatures on the philosophy and economics of science ignore the important downstream economic implications of the non-profit driven institutional framework that governs scientific knowledge accumulation. This paper contributes by identifying scientific institutions and entrepreneurial activity as prerequisites for economic growth and it offers a tentative explanation for the rise and fall in the levels of scientific, entrepreneurial and economic activity over the Kondratieff-cycle.      

一种利用混沌同步的测控系统测距方法

当前测控系统普遍采用的伪码测距体制中存在距离模糊问题和同步捕获问题,并且两者的性能要求是矛盾的。利用混沌信号的非周期、自同步和良好自相关特性,提出了将连续混沌信号作为测距信号应用于航天测控系统的方法,分析了该体制的工程应用可行性,并进行了仿真试验,给出了改进相关性能的方法。混沌测距方法相对于伪码测距的优势在于,混沌的同步特性能够自动实现测距信号的同步,省略了测距信号的捕获过程;混沌的非周期性消除了距离模糊。连续混沌信号在测控系统中的应用是可行且有优势的。

Franchisor Insolvency in Australia: Profiles,Factors, and Impacts

Franchisor failure is enduring and important in terms of cost, nationally and internationally. This article presents research into Australian franchisor firms that went into a form of bankruptcy protection known in Australia as “voluntary administration.” The research was driven by the commonality and divergence of the interests of franchisors and franchisees. The article provides an insight into franchisor failure and its effect on franchisees. It presents the substantial literature survey that was used to frame questions for franchisor administrators to understand issues associated with franchisors in administration. The limited data demonstrate diversity in the treatment of franchisees during the franchisor's administration. In Australia, franchisees remain a captive, financially committed counterparty during insolvency and potentially deliver a great financial benefit to the franchisor's creditors. The article concludes that administration of franchisors does not take into account the distinct relationship between franchisors and their franchisees and provides policy recommendations to address this matter.     

Tense from touch: Examining accidental interpersonal touch between consumers

Retail shopping research recognizes that other consumers in a store can impact a consumer's experience. However, the effects of accidental interpersonal touch (AIT) are only beginning to emerge in the literature. The current research presents three field experiments to illuminate the process that drives AIT effects. This research is the first to show that AIT effects are driven by arousal; specifically tense arousal rather than energetic arousal. The findings build on prior research to investigate moderators of the AIT effect—trait anxiety and social visibility. The findings show that AIT effects are amplified for anxious female consumers and situations where store bystanders activate feelings of embarrassment. Theoretical and managerial implications are offered.     

Corporate social responsibility,investor protection,and the cost of equity: Evidence from East Asia

We document that corporate social responsibility (CSR) activities increase the cost of equity in East Asia. Further, the effect is driven by economies with weak investor protection. Our findings are robust to alternative variable measurements, accounting for endogeneity of CSR, and various methodological specifications. The positive relation between CSR and the cost of equity is attributable to the high agency conflicts in East Asian economies. Our findings highlight that the effect of CSR is contingent on the research context, and emphasize the importance of enhancing investor protection and mitigating agency conflicts for the promotion of CSR.     

Disentangling CEO compensation: A simultaneous examination of time,industry, and firm‐level effects

Despite decades of research, how CEO compensation is determined remains an enigma. Drawing on agency, managerial hegemony, and institutional theoretical perspectives, we use hierarchical linear modelling—a multilevel analytic technique—to examine how firm‐, industry‐, and time‐level effects drive CEO compensation in US corporations. Results show that while cash salary is mostly driven by firm‐specific factors, equity‐based compensation responds to time‐level effects with firm‐ and industry‐level effects playing a marginal role. We argue that such evidence is consistent with the institutionalization of the CEO compensation determination process through the widespread adoption of benchmark peer‐group comparisons. Such practices underlie economy‐wide changes in CEO compensation that are increasingly disconnected from other fundamental firm‐ or industry‐specific factors. Copyright © 2015 ASAC.

‘Atomistic’ and ‘Systemic’ Approaches to Research on New,Technology-based Firms: A Literature Study

The dominating view of new, technology-based firms is that these firms are driven by a heroic entrepreneur who pursues aggressive growth. New, technology-based firms are expected to sooner or later develop tangible products with which new market niches are created and existing ones penetrated. Often the only perceived economic impact of new, technology-based firms is one delivered through rapid organic growth.The argument put forward in the present article is that the conception of new, technology-based firms as growth dynamos is largely misleading and partly the result of the growth bias in the traditional research on new, technology-based firms. In the present article, ten general misconceptions and more or less explicit assumptions of the traditional body of research on new, technology-based firms are contested. Alternative conceptions to replace the traditional ones are proposed. The policy implications of the new conceptions are discussed.     

The Case of the C‐TPAT Border Security Initiative: Assessing the Adoption/Persistence Decisions When Dealing With a Novel,Institutionally Driven Administrative Innovation

The current study examines attributes of a diffusion process associated with an institutionally driven administrative innovation (IDAI) that was designed to mitigate international supply chain logistic risk. Using a sample of firms who adopted this type of administrative innovation (AI), we find that managers' adoption and persistence decisions differed from observed behaviors associated with economically driven AIs. For example, with IDAIs, large firms are the characteristic early adopters and the innovation persists in spite of a lack of a clearly compelling economic rationale for its continued support. These findings are drawn from an analysis of respondent data pertaining to Customs‐Trade Partnership Against Terrorism—an AI that has been previously identified as being an example of such a development. The results prompt us to rethink on the mechanisms governing AI adoption and persistence decisions and enhance the theoretical richness surrounding research into not only IDAIs but also other related areas such as certified management standards.

Moral Hazard,Agency Cost,and Firm Growth

We study how the agency cost implied by the moral hazard problem in a firm dynamics model affects the life cycle growth pattern of firms. In the early stage of a firm's growth, the agency cost restricts the firm's capital input and diminishes over time, so that the firm's growth is driven by efficiency improvements and an exogenous progress in productivity. In the long run, when the firm loses its potential to improve efficiency, growth is driven only by the progress in productivity. As a result of this growth mechanism, consistent with the data, the growth rate and its volatility, as well as Tobin's Q, decrease with age and size. Moreover, the cross‐sectional distributions of firm size and managerial compensation obey a power law, as they do in the data. In addition, the model provides novel implications for how the characteristics of the production technology and the preferences of the economic agents affect the growth pattern of firms, and these implications are potentially testable.

A new innovation paradigm: European cohesion policy and the retreat of public science in countries in Europe's scientific periphery

This article seeks to undertake a critical assessment of the changing position of public science in the entrepreneurial ecosystem of the countries on the periphery of European research. These countries are driven by new innovation paradigm based on entrepreneurship, which are implemented within the European Smart specialization strategy (S3). This article argues that S3 is widely implemented in the cohesion countries and, while it provides substantial resources for science, technology, and innovation, it fails to provide sustainability in the public research sector. This has direct implications for policies concerning innovation and entrepreneurial ecosystems. In order to prove the thesis, the article provides theoretical argumentation for emergence of a new innovation paradigm, driven by the rise of the entrepreneurial ecosystem, its incorporation into S3, and a consequent retreat of science policy in favor of entrepreneurial policy. The empirical analysis is focused on the funding trends seen in the business and public research sectors over the last decade (2008–2017), which have clearly shown that S3 has not contributed, despite expectations, to an increase in public expenditure for science. This signifies S3's neglect of public research within entrepreneurial ecosystems and challenges the ability of S3 to reduce wide disparities in research and innovation performance across the European Union. This ultimately endangers the innovation potential of the entrepreneurial ecosystem itself.     

Ethics of Global Internet,Community and Fame Addiction

Robert Putnam in his book Bowling Alone and subsequent works has analysed the phenomenon that American society increasingly avoids various community driven activities, such as civic associations, activities with friends and family (Putnam, Bowling Alone. Simon and Schuster, New York; 2006). In this paper we introduce the idea that a counterpart to this social trend is a global addiction to fame and celebrity. We believe that the global internet is one of the major drivers of this search for fame for the sake of being famous. However, most people aspiring to be famous celebrities will not succeed in this quest, and become disappointed. The purpose of this paper is to analyse the ethical implications of such social contagion, bandwagon effects in today’s global business environment towards fame and celebrity. The contribution of this paper is to provide a future direction for research on business ethics in terms of this growing global phenomenon of fame and celebrity addiction.
