Model-independent pricing with insider information: a Skorokhod embedding approach

In this paper, we consider the pricing and hedging of a financial derivative for an insider trader, in a model-independent setting. In particular, we suppose that the insider wants to act in a way which is independent of any modelling assumptions, but that she observes market information in the form of the prices of vanilla call options on the asset. We also assume that both the insider's information, which takes the form of a set of impossible paths, and the payoff of the derivative are time-invariant. This setup allows us to adapt recent work of Beiglboeck, Cox and Huesmann (2016) to prove duality results and a monotonicity principle, which enables us to determine geometric properties of the optimal models. Moreover, we show that this setup is powerful, in that we are able to find analytic and numerical solutions to certain pricing and hedging problems

Does social capital determine health? Evidence from eight transition countries

This paper starts from an empirical assessment of different dimensions of social capital in the transition countries of Central and Eastern Europe (CEE) and the Commonwealth of Independent States (CIS). The level of social capital is lower in CEE-CIS countries compared to other countries in Europe and beyond. We then use a unique data source to carefully investigate the impact of social capital on individual self-reported health for eight countries from the Commonwealth of Independent States (Armenia, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, Ukraine). We rely on three indicators for social capital – individual degree of trust, participation in local organisations, social isolation – and employ alternative procedures to consistently estimate the impact of social capital on health. We attempt to circumvent the endogeneity problems by using instrumental variable estimates. Our results show that, in the overall sample comprising all eight countries, the individual degree of trust is positively and significantly correlated with health, either in pooling estimation or when we rely on IV estimators with community fixed effects. Similarly, social isolation is negatively and significantly associated with health, irrespective of the procedure of estimation. On the other hand, the effect of being member of a Putnamesque organisation is more ambiguous and usually not significantly related to health. Finally, country-estimates suggest that the impact of social capital on health varies across the eight countries. We argue that the positive effect of membership on health is conditional on the quality of the political institutions and civil liberties, while trust and social isolation seem to influence health independently of those institutional factors.Health; social capital; instrumental variables; transition countries

NLO Vertex for a Forward Jet plus a Rapidity Gap at High Energies

We present the calculation of the forward jet vertex associated to a rapidity gap (coupling of a hard pomeron to the jet) in the BFKL formalism at next-to-leading order (NLO). Real emission contributions are computed via Lipatov's effective action. The NLO jet vertex turns out to be finite within collinear factorization and allows, together with the NLO non-forward gluon Green's function, to perform NLO studies of jet production in diffractive events (e.g. Mueller-Tang dijets).Comment: 4 pages, Proceedings of DIFFRACTION 2014 (Primo\v{s}ten, Croatia, September 2014

The Gluon-Induced Mueller-Tang Jet Impact Factor at Next-to-Leading Order

We complete the computation of the Mueller-Tang jet impact factor at next-to-leading order (NLO) initiated in arXiv:1406.5625 and presented in arXiv:1404.2937 by computing the real corrections associated to gluons in the initial state making use of Lipatov's effective action. NLO corrections for this effective vertex are an important ingredient for a reliable description of large rapidity gap phenomenology within the BFKL approach.Comment: 32 pages, many figure

Semi-static completeness and robust pricing by informed investors

We consider a continuous-time financial market that consists of securities available for dynamic trading, and securities only available for static trading. We work in a robust framework where a set of nondominated models is given. The concept of semi-static completeness is introduced: it corresponds to having exact replication by means of semi-static strategies. We show that semi-static completeness is equivalent to an extremality property, and give a characterization of the induced filtration structure. Furthermore, we consider investors with additional information and, for specific types of extra information, we characterize the models that are semi-statically complete for the informed investors. Finally, we provide some examples where robust pricing for informed and uninformed agents can be done over semi-statically complete models

Volatile sedation in sepsis: a promising therapeutic approach or a venture doomed to fail?

Preclinical strategies targeting sepsis often had a single target and could not be translated into the clinical setting. Volatile sedation modulates multiple aspects of inflammation and improves sepsis-related survival in animal models. Whether a similar effect can be achieved in humans is unclear. Only a prospective clinical trial will be able to answer this question. The implementation of such a study in times when volatile anaesthetics are the focus of attention because of their greenhouse effect and their carbon dioxide emission will be a challenge, even though the alternative, i.v. sedation, is still insufficiently investigated in this respect

INDIVIDUAL FACTORS IN THE DEVELOPMENT OF NEGATIVE MATHEMATICS SELF-CONCEPT AMONG GIRLS AT A RURAL SCHOOL IN CENTRAL PROVINCE, ZAMBIA

This study was centred on ascertaining individual factors which influence the development of negative Mathematics self-concept in girls. The research was based on a single case study and utilized the qualitative research approach. The sample consisted of a total of 18 participants. Thus, a sample of seven grade 11 girls with low Mathematics self-concept, seven parents to the girls and four teachers of Mathematics at the school were purposively selected from Mwabonwa (pseudonym) Girls’ Secondary School situated in a rural area of Central Province of Zambia. In-depth interviews were conducted with girls, teachers and parents. A focus group discussion was held with pupils only and a document review to understand pupils’ statuses and their past academic performance was employed. Data was analysed with the use of the Interpretative Phenomenological Analysis (IPA) Method. A number of indicators revealed two key individual factors influencing low Mathematics self-concept in girls. These factors include: girls’ negative perceptions of Mathematics and poor Mathematics background. In a nutshell, these findings show that to understand the low self-concept girls have in Mathematics one had to appreciate the individual experiences of the girls in the subject.  Article visualizations
