The Commodification of Self‐Esteem: Branding and British Teenagers

This study explores the role of consumption in the lives of British adolescents, with a particular focus on its role in forming and maintaining self‐esteem. Through a large qualitative study, over 100 adolescents revealed their attitudes and feelings toward consumption—particularly fashion. It was found that as a result of peer pressure and the importance of conformity among adolescents, consuming the correct possessions at the right time, is essential for social acceptance, gaining and maintaining friendships and thus self‐esteem. This paper argues that self‐esteem has been commodified. The consequences of failing to “keep up” with consumption trends were revealed; these include social exclusion, negative peer evaluation, and reduced self‐esteem. Moreover, these negative consequences were particularly pronounced among adolescents from low‐income families who, in contrast to their financial status, were eager to purchase the more expensive brands. Adolescents appear to have a striking awareness of the role of branding, advertising, and peer pressure in forming their consumption attitudes, yet they are unable to resist them. The findings from this study highlight the need for a rethinking of the more traditional components of adolescent self‐esteem.     

Un/ethical Company and Brand Perceptions: Conceptualising and Operationalising Consumer Meanings

Based on three empirical studies, this research sets out to conceptualise and subsequently operationalise the construct of consumer perceived ethicality (CPE) of a company or brand. Study 1 investigates consumer meanings of the term ethical and reveals that, contrary to philosophical scholars?? exclusively consequentialist or nonconsequentialist positions, consumers?? ethical judgments are a function of both these evaluation principles, illustrating that not any one scholarly definition of ethics alone is capable of capturing the content domain. The resulting conceptualisation identifies six key themes explicating the construct. Building upon these findings, studies 2 and 3 were conducted to operationalise CPE. Such operationalisation is an essential prerequisite for future explorations and theory development given the absence of a suitable tool to capture and quantify the strength and direction of CPE. The key focus was on developing a valid and reliable multi-item measurement tool that is practical, parsimonious and easy to administer. The scale??s general applicability allows deployment in academic and business contexts as well as different research areas and doing thus facilitates the much-needed theory building in this new research area.     

Exploring origins of ethical company/brand perceptions — A consumer perspective of corporate ethics

This research provides a consumer perspective of corporate ethics. The study consists of twenty long interviews [McCracken, G., 1988. The long interview. Newbury Park, CA: Sage] with general consumers, and conceptualizes potential sources of consumer perceived ethicality (CPE) of a company/brand by investigating consumers' ethical perceptions of business behavior. The developed taxonomy delineates six domains and 36 sub-domains of CPE origin, relating to the impact corporate behavior has on: (1) consumers, (2) employees, (3) the environment, (4) the overseas community, (5) the local economy and community, and (6) the business community. Findings demonstrate disparities between the consumer and the business perspective and highlight the fact that sources of CPE prove considerably more diverse and complex than the literature suggests, therefore presenting a vital extension to existing research. By providing business managers with a comprehensive assembly of issues which may evoke un/ethical perceptions, the framework may serve as a code of business conduct to prevent, contain, or combat negative CPE.     

Shocks at large banks and banking sector distress: The Banking Granular Residual

Size matters in banking. In this paper, we explore whether shocks originating at large banks affect the probability of distress of smaller banks and thus the stability of the banking system. Our analysis proceeds in two steps. In a first step, we follow Gabaix [Gabaix, X., 2008a. The Granular Origins of Aggregate Fluctuations. Available at SSRN: http://ssrn.com/abstract=1111765] and construct a measure of idiosyncratic shocks at large banks, the so-called Banking Granular Residual. This measure documents the importance of size effects for the German banking system. In a second step, we incorporate this measure of idiosyncratic shocks at large banks into an integrated stress-testing model for the German banking system following De Graeve et al. (2008). We find that positive shocks at large banks reduce the probability of distress of small banks.     

Economics at the FCC, 2016–2017: Auction Designs for Spectrum Repurposing and Universal Service Subsidies

The Federal Communications Commission is responsible for federal regulation in the telecommunications and electronic media sectors, and for management of the nation’s non-federal radio frequency spectrum. During the past year, Commission economists contributed to the agency’s ongoing efforts to use market-based mechanisms—such as auctions—to allocate spectrum and distribute universal service subsidies efficiently. This includes repurposing broadcast television spectrum for more efficient use by wireless service providers through the recently concluded Broadcast Incentive Auction and structuring auction mechanisms to promote efficient allocation of universal service subsidies for the increased build-out of mobile wireless and fixed broadband service in unserved and underserved areas.     

Politikvermittlung durch Boulevardjournalismus

Research on tabloid journalism suffers from two shortcomings: On the one hand, scholars regard tabloid journalism mostly as an entertaining but apolitical form of journalism with little societal relevance. On the other hand, empirical research measures a variety of supposedly tabloid features but fails to ground these aspects in a theoretical concept of tabloid journalism. The paper addresses these shortcomings by theorizing tabloid media as mediated arenas for a distinct public sphere, which may very well contribute to the political functions of mass media for democracy. On this theoretical basis, the paper identifies indicators that researchers should consider when measuring the political dimension of tabloid journalism.     

Modelling Co-movements and Tail Dependency in the International Stock Market via Copulae

This paper examines international equity market co-movements using time-varying copulae. We examine distributions from the class of Symmetric Generalized Hyperbolic (SGH) distributions for modelling univariate marginals of equity index returns. We show based on the goodness-of-fit testing that the SGH class outperforms the normal distribution, and that the Student-t assumption on marginals leads to the best performance, and thus, can be used to fit multivariate copula for the joint distribution of equity index returns. We show in our study that the Student-t copula is not only superior to the Gaussian copula, where the dependence structure relates to the multivariate normal distribution, but also outperforms some alternative mixture copula models which allow to reflect asymmetric dependencies in the tails of the distribution. The Student-t copula with Student-t marginals allows to model realistically simultaneous co-movements and to capture tail dependency in the equity index returns. From the point of view of risk management, it is a good candidate for modelling the returns arising in an international equity index portfolio where the extreme losses are known to have a tendency to occur simultaneously. We apply copulae to the estimation of the Value-at-Risk and the Expected Shortfall, and show that the Student-t copula with Student-t marginals is superior to the alternative copula models investigated, as well the Riskmetics approach.     

Overnight stock returns and realized volatility

The information flow in modern financial markets is continuous, but major stock exchanges are open for trading for only a limited number of hours. No consensus has yet emerged on how to deal with overnight returns when calculating and forecasting realized volatility in markets where trading does not take place 24 hours a day. Based on a recently introduced formal testing procedure, we find that for the S&P 500 index, a realized volatility estimator that optimally incorporates overnight information is more accurate in-sample. In contrast, estimators that do not incorporate overnight information are more accurate for individual stocks. We also show that accounting for overnight returns may affect the conclusions drawn in an out-of-sample horserace of forecasting models. Finally, there is considerably less variation in the selection of the best out-of-sample forecasting model when only the most accurate in-sample RV estimators are considered.
