Speculative Attacks with Multiple Sources of Public Information*

We propose a speculative attack model in which agents receive multiple public signals. Diverse pieces of public information can be taken into account differently by different players and are likely to lead to different appreciations ex post. This process defines players' expected private values of a successful attack. The main result shows that equilibrium uniqueness depends on two conditions: (i) signals are sufficiently dispersed and (ii) private beliefs about signals' relative precision differ sufficiently. We derive some implications for information dissemination policy. Transparency in this context is multidimensional: it concerns the publicity of announcements, the number of signals disclosed and their precision.     

From drifter to gap year tourist: Mainstreaming Backpacker Travel

Long-haul, long-term independent travel—here backpacking—has become increasingly common over the last few decades. Once considered a marginal activity undertaken by society’s drop-outs, it has gradually entered the tourism mainstream. Based on interview and internet material and ethnographic field research, this article considers where this growth in interest has come from, and how transformations in the perception of backpacking have taken place. Focusing on the travel imagination, it examines socioeconomic and cultural “incitements to travel”. As backpacking has become more mainstream its “alternative” standing has diminished, but it continues to be a potentially status-enhancing activity.     

What is the role of consensus statements in a risk society?

Abstract

This paper explores the role of consensus statements in a risk society. It uses Beck’s theory of risk to show that scientists have employed consensus statements in order to re-establish faith in science. Through analysing the goals of participants in consensus fora and comparing them to the fora processes, this paper considers how consensus statements and guidelines in public health can be viewed as remedies for the decline in expert trust experienced in the current risk society. To collect data, 25 interviews were undertaken with consensus panel participants from the USA, UK and Australia. Interviewees were from peak national agencies/commissioning agencies and were categorised as policymaker, practitioner and consumer stakeholders. Participants made recommendations for improving consensus processes in order to mitigate perceptions of risk. These were: (1) clearly stated goals; (2) robust, evidence-based and transparent processes of methodological development and participation/deliberation/decision-making; (3) diverse stakeholder representation, including increased consumer participation; (4) transparency about conflicts of interest; and, (5) robust, carefully worded recommendations. Poor-quality consensus statements can further entrench scepticism about the scientific enterprise. While consensus statements can be seen as a tool for moderating perceptions of risk, policymakers and scientists must ensure the integrity, strength and transparency of their research methods. This has the potential to facilitate policy, improve scientific accountability to the public and legitimise processes. While fostering greater trust is not a primary objective for scientists, an increase in legitimacy of process can be an important unintended consequence of improved quality consensus statements and an important antidote to the risk society.     

Band or point inflation targeting? An experimental approach

We conduct laboratory experiments with human subjects to test the rationale of adopting a band versus point inflation targeting regime. Within the standard New Keynesian model, we evaluate the macroeconomic performances of both regimes according to the strength of shocks affecting the economy. We find that when the economy faces small uncorrelated shocks, the level of inflation as well as its volatility are significantly lower in a band targeting regime, while the output gap and interest rate levels and volatility are significantly lower in a point targeting regime with tolerance bands. However, when the economy faces large uncorrelated shocks, choosing the suitable inflation targeting regime is irrelevant because both regimes lead to comparable performances. These findings stand in contrast to those of the literature and question the relevance of clarifying a mid-point target within the bands, especially in emerging market economies more inclined to large and frequent shocks.     

Österreichs Alterssicherung: Vorbild für Deutschland?

As a result of political reforms, pension provision in Germany is the task of a multi pillar model including private and occupational schemes in addition to the public pension insurance. By contrast, the Austrian single pillar model has been developed into an encompassing public insurance system now also covering the self employed and civil servants. A comparison of the two countries shows that the Austrian system provides much higher benefits. Economic developments in Germany and Austria have been rather close in recent years. This, we argue, shows that a strong public pension insurance does not hamper a country’s economic performance.     

Ageing in Europe

For many people all over Europe, there is an understanding and an expectation that in old age they will be taken care of by the state. High social security contributions throughout the three or four decades of a working life are rationalised by the prospect of a straightforward transition out of the labour force when the time comes. While this was a reasonable expectation in decades past, a number of factors have combined to cause people all across the continent to feel very anxious about what awaits them once it is time to exit the labour force into retirement. The well-documented demographic transition of many rich European countries is a big factor, as greying populations start to weigh on the sparser younger generations, leading to increasing dependency ratios that would cause any social security system to buckle. The Great Recession has not helped matters, and the austerity measures still crippling many vulnerable European nations will not make anyone in these countries feel optimistic about their post-working lives. The following papers look at different threads of the new reality of ageing in Europe, from pension reform and prolonging the working life to more qualitative aspects such as an analysis of the quality of life of the elderly across Europe. They serve to inform and advise on an important issue that will affect everyone in Europe at some point in their lives.     

Rethinking the Links between Human Relationships and Economic Efficiency Using Local Institutions: The Case of Two Emerging Economies

Emerging countries around the world have been growing fast over the last thirty years, with most of these countries basing their economic development on a state capitalism. Within these countries, there is a concentration of wealth in the hands of a few people. This fact confirms the analysis of Thorstein Veblen (1898 Veblen, Thorstein. “Why Is Economics Not an Evolutionary Sciences?” Quarterly Journal of Economics 12, 2 (1898): 373–397.[Crossref] , [Google Scholar]) who shows the gap that exists between the vested interest of the rich and the unmet needs of the poor. The world happiness report (Helliwell, Layard and Sachs 2016 Helliwell, John F., Richard Layard and Jeffrey Sachs, eds. World Happiness Report 2016. World Happiness, 2016. Available at http://worldhappiness.report/wp-content/uploads/sites/2/2016/03/HR-V1_web.pdf. Accessed December 1, 2016. [Google Scholar]) also shows for the emerging economies a gap between the world rank in economic growth and in wellbeing. I propose a new paradigm of development for two emerging economies, Brazil and South Africa, by putting human development in the center of economic development and by using different approaches in economics and psychology. My analysis links the theories of Carl Shapiro and Joseph E. Stiglitz regarding “efficiency wages” (1984 Shapiro, Carl and Joseph E. Stiglitz. “Equilibrium Unemployment as Worker Disciplines Devices.” American Economic Review 74, 3 (1984): 433–444.[Web of Science ®] , [Google Scholar]) with the complexity approach (Le Moigne 1995 Le Moigne, Jean-Louis. La modélisation des systèmes complexes. Paris, France: Dunod, 1995. [Google Scholar]). This approach combines the results of positive psychology (Kahneman 2011 Kahneman, Daniel. Thinking, Fast and Slow. London, UK: Penguin, 2011. [Google Scholar]) with the role of local institutions for improving the economic development of emerging economies (Deaton 2016 Deaton, Angus. La grande évasion: Santé, richesse et origine des inégalités. Paris, France: PUF, [2015] 2016. [Google Scholar]). In the first section of the article, I examine definitions of economic and human wealth. In the second section, I analyze the gaps that exist between the standard-of-living ranking and the wellbeing ranking for both Brazil and South Africa in order to present meso-happiness indexes linking the micro- and macro-levels of human wealth. In the last section, I analyze the way local institutions in Brazil and South Africa could create dynamic links for these countries’ efficient functioning in the world economy.     

Exploring professional human brand identity through cultural and social capital: a typology of film director identities

ABSTRACT

Our research focuses on film director human brands. It addresses the issue of human brand identity construction through the social valuation of identity attributes linked to cultural capital. Based on Bourdieu’s theory of cultural and social capital, we examine the identity attributes on which human brand identities are built through the acquisition of legitimacy. We conduct a qualitative study combining three context levels of analysis (external, internal and individual). Our results reveal the existence of four human brand identity types (i.e. chameleon conformist, niche archetypecast, mass archetypecast, cultural influencer), thus enriching and extending previous research. Each identity type is characterised by a set of culturally valued identity attributes, associated with legitimacies – specific, bourgeois, popular and institutional – bestowed by human brand constituencies.     

Improving the Decision Making Process in the Design Project by Capitalizing on Company’s Crucial Knowledge

In this paper, we propose a method to locate the companys crucial knowledge for improving the quality of decision making in a design project. It comprises of a preliminary survey regarding the approach that has been carried out at automotive company for identifying the crucial knowledge, aiming at choosing and justifying the necessary investment to capitalize on the knowledge. This method will then be used as basis for a dialogue between the stakeholders involved in the identification of the crucial knowledge developed and/or used in a design project.
