Intellectual property rights as development determinants

Abstract While intellectual property rights (IPRs) are the key drivers of economic performance in R&D based growth models, they have not been fully explored in empirical development studies. We introduce IPRs to this literature, using Two‐Stage Least Squares Bayesian Model Averaging to address endogeneity and model uncertainty at the instrument and income stages. We show that IPRs exert effects similar to ‘Rule of Law’ and therefore provide robust evidence that both physical and intellectual property rights are crucial development determinants. We document that unenforced IPRs exert no effect on development. Instead, it is the level of enforced IPRs that causes development.

Where there's a will,there's a way! A practitioner's view

This contribution is focused on the gaps which exist between regulation and its practical effects. It does refer to the possible implications of the Maastricht Treaty on future EC consumer policy but is not at all limited to this aspect of the issue. The goal is rather to shed some light on the practical difficulties encountered by consumer representatives in the adoption of EC consumer policy initiatives, in contrast to the more theoretical approach adopted by some other contributors to this issue. It also refers to some of the positive developments which have taken place, as a response to consumer activism, within the EC.

Wo ein Wille ist, ist auch ein Weg! Eine Meinung aus der Praxis

Zusammenfassung Der Beitrag befa\t sich mit der Lücke, die zwischen Absichten der Regulierung und ihren praktischen Auswirkungen besteht. Er bezieht sich zwar auf die möglichen Implikationen des Vertrages von Maastricht für die künftige Verbraucherpolitik der Gemeinschaft, ist aber keineswegs auf diesen Aspekt beschränkt. Vielmehr werden die praktischen Schwierigkeiten beleuchtet, denen sich Verbraucherrepräsentanten bei der übernahme von verbraucherpolitischen Initiativen der Gemeinschaft gegenübersehen — ein Blickwinkel, der sich von den eher theoretischen Perspektiven mancher anderer Beiträge zu diesem Heft unterscheidet. Behandelt werden auch einige positive Entwicklungen, die als Antwort auf Konsumentenaktivitäten innerhalb der Europäischen Gemeinschaft stattgefunden haben.

Perceived organizational support and knowledge sharing: employees’ self-construal matters

Abstract

HR professionals are expected to become more involved in knowledge management and facilitate knowledge sharing among employees in the knowledge economy. In this study, we investigated the relationship between perceived organizational support and knowledge sharing by taking account of employees’ interdependent and independent self-construal. Our hypotheses were examined using a 2-wave survey data-set from 145 teachers working at 4 Dutch vocational education and training schools. The results showed that perceived organizational support was positively related to knowledge sharing for employees either with a high interdependent self or with a low independent self. However, this positive relationship disappeared for employees either with a low interdependent self or with a high independent self. Overall, the moderating effect of self-construal revealed a new avenue towards a better understanding of the relationship between organizational support and employees’ knowledge sharing. It provided a tentative answer to the question of why organizational support does not often succeed in motivating employees to share their knowledge in the workplace.     

Beyond Seeing McDonald's Fiesta Menu: The Role of Accent in Brand Sincerity of Ethnic Products and Brands

Given the significant increase in the number of ethnic consumers, firms attempt to utilize various marketing communication strategies and tactics to promote their brands to these ethnically diverse groups. Similarly, many marketers are striving for brand crossovers by introducing ethnic offerings to new audiences. This research focuses on one such ethnic marketing communication strategy—the use of accented spokespersons. Building on a prosodic theory of accent, we propose that certain prosodic features (i.e., intonation) connote associations of sincerity and trustworthiness and thus affect brand sincerity perceptions. The current research also demonstrates that the effect of intonation depends on the degree of congruity between product ethnicity and a spokesperson's accent. Our results reveal that when these variables are congruent, consumers rely on the cues that are consistent with the advertising appeals. Thus, when a message uses a sincerity appeal, falling (versus rising) intonation leads to greater attributions of brand sincerity, whereas when a message uses a competence appeal, rising (versus falling) intonation triggers higher perceptions of brand sincerity. In the condition of incongruity, consumers aim to resolve the incongruity and rely on cues that connote the trustworthiness of a message (i.e., falling intonation). Theoretical and managerial implications conclude the article.     

Conic martingales from stochastic integrals

In this paper, we introduce the concept of conic martingales. This class refers to stochastic processes that have the martingale property but that evolve within given (possibly time‐dependent) boundaries. We first review some results about the martingale property of solution to driftless stochastic differential equations. We then provide a simple way to construct and handle such processes. Specific attention is paid to martingales in [0, 1]. One of these martingales proves to be analytically tractable. It is shown that up to shifting and rescaling constants, it is the only martingale (with the trivial constant, Brownian motion, and geometric Brownian motion) having a separable diffusion coefficient and that can be obtained via a time‐homogeneous mapping of Gaussian diffusions. The approach is exemplified by modeling stochastic conditional survival probabilities in the univariate and bivariate cases.     

LOUD AND CLEAR? CAN WE HEAR WHEN THE SARB SPEAKS?

Inflation targeting is a forward‐looking framework for monetary policy that has brought unprecedented transparency to the process of monetary policy. This paper aims to assess the degree to which the South African Reserve Bank's (SARB) Monetary Policy Committee (MPC) has, since the introduction of inflation targeting, successfully communicated to the public its policy analysis, and, in particular, the expected future policy changes. It follows international literature in constructing a numerical index that is used to reflect the information content of the SARB's communications, specifically the monetary policy statements that accompanied each of the MPC meetings since 2000. This method allows us to judge, systematically, the degree to which the MPC has communicated successfully, and the evolution of that success over the past nine years. We find evidence that the MPC has succeeded in signalling their likely future policy decision with consistency over this period.     

Hazard rate for credit risk and hedging defaultable contingent claims

We provide a concise exposition of theoretical results that appear in modeling default time as a random time, we study in details the invariance martingale property and we establish a representation theorem which leads, in a complete market setting, to the hedging portfolio of a vulnerable claim. Our main result is that, to hedge a defaultable claim one has to invest the value of this contingent claim in the defaultable zero-coupon.Received: April 2003Mathematics Subject Classification: 91B24, 91B29, 60G46JEL Classification: G10The authors would like to thank D. Becherer and J.N. Hugonnier for interesting discussions and the anonymous referee whose pertinent questions on the first version of this paper help them to clarify the proofs.

Risk communication and social media during food safety crises: a study of stakeholders’ opinions in Ireland

Social media is a particular communication platform which has witnessed an exponential growth in use and influence in recent years, democratising the communication process, and offering risk communicators a way of putting into practice those principles which are advocated to be at the core of risk management and communication. However, little is known about stakeholders’ willingness to embrace this new form of communication in a food crisis. The current study presented an exploratory investigation of the opinions of Irish stakeholders on the position of risk communication in a crisis, with a particular focus on understanding what application social media may have. In-depth one-to-one interviews were carried out with key stakeholders holding frontline positions in managing and communicating about risk in the food sector in Ireland. The stakeholders identified risk communication as a central activity in a food safety crisis, driven by an obligation to protect both consumer health and the reputation of the Irish food sector. Stakeholders relied primarily on risk communication to disseminate information in a crisis so to educate and inform the public on a risk and to prevent confusion and alarmism; most did not explicitly value two-way risk communication in a crisis. The ability to effectively manage future crises may depend on stakeholders’ willingness to adapt to the changing communication landscape, namely – their willingness to adopt social media and use it effectively. The findings indicate that the stakeholders interviewed are appreciative of the need to engage with social media in times of a food safety crisis. However, most valued social media as a one-way channel to help spread a message and there was little reference to the interactive nature of this medium. Implications for integrating social media into crisis risk communication strategies are discussed.
