In this article we survey methods of dealing with the following problem: A financial agent is trying to hedge a claim C, without
having enough initial capital to perform a perfect (super) replication. In particular, we describe results for minimizing
the expected loss of hedging the claim C both in complete and incomplete continuous-time financial market models, and for
maximizing the probability of perfect hedge in complete markets and markets with partial information. In these cases, the
optimal strategy is in the form of a binary option on C, depending on the Radon-Nikodym derivative of the equivalent martingale
measure which is optimal for a corresponding dual problem. We also present results on dynamic measures for the risk associated
with the liability C, defined as the supremum over different scenarios of the minimal expected loss of hedging C.

Standard optimal portfolio selection models take no account of the special information that active investors believe they
possess. For example, active investors who believe they can place bounds on the price of a security will want to use that
information when assessing risk and expected return in order to construct an optimal portfolio. In this paper, we use two
continuous-time models to analyze how placing boundaries on the price of a stock affects assessed risk, expected returns,
and the optimal holdings of an active investor, and how those vary as a function of the relation between the stock price and
the boundaries. In particular, the optimal strategy takes significant long/short positions as the price nears its lower/upper
boundary. 相似文献

This paper is a contribution to sensory‐aware cultural consumer research. It suggests that while the audio‐visual domain is unquestionably a crucial ingredient of contemporary consumer culture, there is a pressing need to explore the role of the other senses as well. The study works towards a practice‐based culturalist approach to sensory ethnography, a perspective that allows consumer scholars to empirically account for the cultural aspects of the senses. Through an empirical case study on sport fishing, the paper scrutinizes the challenges and opportunities related to conducting sensory ethnography. In addition, it discusses the benefits of this approach in consumer research. 相似文献

In this paper we examine how Finnish Governments dismantled the Nordic welfare state paradigm from the 1990s onwards and adopted Schumpeterian ideas of a competitive workfare state. In the early 1990s, Finland went through a financial crisis that was the most severe in OECD countries since the Second World War and came to play a major role in the paradigm change. In the crisis, the Ministry of Finance gained a central role as a consensus-building power broker, and formulated a political strategy of national competitiveness, which was adopted as a rationale of power for consensual governments and has been maintained since. We suggest that financial crises can become formative moments in which new ideas are adopted and policies are reformulated. They can also become moments which provide opportunity to overcome citizen opinion. In Finland, the wide popular and party support for the Nordic welfare model was not reflected in the new paradigm. 相似文献

In 2012, the iNTeg-Risk project (www.integrisk.eu-vri.eu) has successfully finished its first 3?years of work. At this point, the project has already yielded a part of large set of results envisaged for its 4.5?years long work plan. This paper recalls the main goals of the project and analyzes the results delivered; as for instance, the work done in single emerging risk representative applications, the work on the development on the iNTeg-Risk paradigm, framework and methodologies of/for emerging risk management, the work on ‘iNTeg-Risk 1StopShop’ (the platform for integrating project results) and its main elements –Risk Atlas, RiskEars (the database of early emerging risk indications/notions), the database of key performance indicators, the work on Safetypedia, etc. The work on harmonization of practices when dealing with emerging risks is certainly the most relevant result in the first years of work on the project. The work has been based on (a) the comparison of different application areas and (b) definition of the elements needed for building the ‘common European approach’ to emerging risks. Some real-life events which took place in the first 2?years of the project (e.g. oil spill in Gulf of Mexico, Fukushima disaster accident in Viareggio, incidents caused by unmanned devices, natural hazards in populated areas, …) have clearly justified some of the choices made in the definition phase of the project. In addition, they have confirmed the need to strengthen the efforts needed to achieve a common understanding about principles of dealing with emerging risks on the broader level – e.g. in the area of EU standardization where the respective preparatory work has started, too. 相似文献

Nowadays, helicopters have been used in maritime transportation to serve offshore platforms. This paper outlines methodology for assessing safety risks by operating in the vicinity of helidecks. During each flight, decisions must be made regarding the events that involve interactions between the four safety risk elements – the pilot in command, the aircraft, the environment and the operation. This paper evaluates helicopter crash statistics based on region and flight phase. Data collected were used for developing methodology for computing the helicopter impact frequency into facility of interest. The analysis for helicopter impact frequency calculations is based on number of operations, crash rate, frequency, average length of flight and crash area. Furthermore, the conclusion was defined based on future measurements for helicopter accidents mitigation or reduction. The presented paper contributes to safety risk assessment in helicopter maritime operations. 相似文献

Endogenous economic freedom and the wealth of nations: evidence from a panel of countries, 1996–2011
Indexes of economic freedom measure the degree to which the policies and institutions of countries are supportive of economic freedom. The authors find a considerable scope for improvement in Index of Economic Freedom, created by Heritage Foundation, since not all components of index have equal effect on economic well-being. Contrary to Heritage methodology the authors tackle the aggregation bias and highlight that each index component contributes differently to the level of economic freedom and subsequently to the level of income per capita. The level of fiscal freedom and monetary freedom exert the strongest influence on the overall index of economic freedom. Authors present the new endogenous cross-country ranking of 135 countries from Instrumental Variable-Two Stage Least Squares (IV-2SLS) empirical specification which removes the inconsistencies arising from the arbitrary assumption of the equivalent effect of each component on the overall index and, hence, the level of real income per capita. 相似文献

The significance of body and gender in the formation of consumers’ identities and agencies has been widely scrutinized. Nevertheless, this study argues that this formation is not fully understood, unless the role of height is taken into account. It leans on a practice-based perspective and critical auto-ethnographic methodology so as to examine how a distinct agency is fabricated for a short-sized female body by a whole range of social, material, and sensory practices that are continuously enacted across various domains of life. It thereby adds to the existing literature on body, gender, and consumer agency by way of incorporating height into critical inquiries this far mostly concerned with weight; by way of materializing and sensorializing the fabrication of an embodied consumer agency this far addressed in visual terms; and by way of considering everyday life as the site in which it continuously unfolds. These insights bear important implications for the development of body politics. 相似文献
