VALUATION OF BARRIER OPTIONS VIA A GENERAL SELF‐DUALITY

Classical put–call symmetry relates the price of puts and calls under a suitable dual market transform. One well‐known application is the semistatic hedging of path‐dependent barrier options with European options. This, however, in its classical form requires the price process to observe rather stringent and unrealistic symmetry properties. In this paper, we develop a general self‐duality theorem to develop valuation schemes for barrier options in stochastic volatility models with correlation.     

Profiling the segments of senior tourists throughout motivation and travel characteristics

Interest in tourism market segmentation of seniors has been increasing in recent years as the tourism industry has begun to be aware of their importance for the sector. This is a very heterogeneous group, with greater purchasing power and lifestyle-oriented entertainment and enjoyment of leisure time by performing travel than previous generations. This study strives to contribute towards the hitherto scarce research on segmentation in senior tourism. Specifically, this work aims to determine the existence of various profiles of senior tourism by means of using socio-demographic variables, motivation and characteristics of travel of seniors. For this, two complementary analysis techniques, the nonlinear canonical correlation (OVERALS) and a two-stage cluster analysis, were used. Five market segments were identified according to the behavioural variables analysed that allow marketers to target this group in the most convenient manner and to exploit new market opportunities.     

A Note on Loadings and Deductibles: Can a Vicious Circle Arise?

In a recently reprinted paper Borch wonders whether an increase in insurance loadings, together with the consequent increase in customers' deductibles, may be the start of a vicious circle, in which higher deductibles produce higher loadings and vice versa, ad infinitum. This paper rules out the possibility of a vicious circle, in a model à la Borch. First of all, increases in costs of the type considered by Borch are not necessarily followed by increases in loadings. Second, increases in loadings are not necessarily followed by increases in deductibles, since in equilibrium insurance may be Giffen. Last but not least, loadings do not increase with deductibles, because the only viable equilibrium is a Stackelberg one.     

The asymptotic expansion of the regular discretization error of Itô integrals

We study an Edgeworth‐type refinement of the central limit theorem for the discretization error of Itô integrals. Toward this end, we introduce a new approach, based on the anticipating Itô formula. This alternative technique allows us to compute explicitly the terms of the corresponding expansion formula. Two applications to finance are given; the asymptotics of discrete hedging error under the Black–Scholes model and the difference between continuously and discretely monitored variance swap payoffs under stochastic volatility models.     

Are entrepreneurial venture's innovation rates sensitive to investor complementary assets? Comparing biotech ventures backed by corporate and independent VCs

Entrepreneurial ventures are a key source of innovation. Nowadays, ventures are backed by a wide array of investors whose complementary asset profiles differ significantly. We therefore assert that entrepreneurial ventures can no longer be studied as a homogeneous group. Rather, we harness the inherent dichotomy in the profiles of independent VCs and corporate investors to study ventures' innovation outcomes. Our sample consists of 545 U.S. biotechnology ventures founded between 1990 and 2003 and backed by independent venture capitalists (VCs) or corporate VCs (CVC). We find CVCs' investees exhibit higher rates of innovation output, compared to independent VC‐backed peers. Moreover, the performance of CVC‐backed ventures is sensitive to their ability to leverage corporate assets, underscoring the role of CVC accessibility and FDA approval requirements as the mechanisms associated with CVC contribution.

Target volatility option pricing in the lognormal fractional SABR model

We examine in this article the pricing of target volatility options in the lognormal fractional SABR model. A decomposition formula of Itô's calculus yields an approximation formula for the price of a target volatility option in small time by the technique of freezing the coefficient. A decomposition formula in terms of Malliavin derivatives is also provided. Alternatively, we also derive closed form expressions for a small volatility of volatility expansion of the price of a target volatility option. Numerical experiments show the accuracy of the approximations over a reasonably wide range of parameters.     

Dependence calibration and portfolio fit with factor-based subordinators

The paper explores the properties of a class of multivariate Lévy processes used for asset returns. We focus on describing both linear and non-linear dependence in an economic sensible and empirically appropriate way. The processes are subordinated Brownian motions. The subordinator has a common and an idiosyncratic component, to reflect the properties of trade, which it represents. A calibration to a portfolio of 10 US stock indices returns over the period 2009–2013 shows that the hyperbolic specification has a very good fit to marginal distributions, to the overall correlation matrix and to the return distribution of both long-only and long-short random portfolios, which also incorporate non-linear dependence. Their tail behaviour is also well captured by the variance gamma specification. The main message is not only the goodness of fit, but also the flexibility in capturing dependence and the ease of calibration on large sets of returns.     

Growth of born globals: the role of the entrepreneur’s personal factors and venture capital

This paper examines to what extent the human capital of entrepreneurs and the receipt of venture capital (VC) financing affect the growth of born globals (BGs). The study analyzes a sample of 242 BGs resulting from a survey on high-tech start-ups operating in the ICT and electronics sectors, located in different countries throughout the world. A multivariate explorative analysis controlling for the endogenous nature of VC is conducted. The results indicate that the experience of the entrepreneur in having previously established another entrepreneurial firm positively affects the growth of BGs. A negative effect is associated with the presence of heterogeneity in the management team in terms of education background. With regard to the linkage between financial capital and growth, it is found that both VC financing and the number of founders (a proxy for the availability internal capital) positively influence the growth of BGs.     

Drivers of productivity in Vietnamese SMEs: the role of management standards and innovation

Using a rich panel dataset of small and medium scale manufacturing enterprises (SMEs) active in the manufacturing sector in Viet Nam, this paper investigates the drivers of firm productivity, focusing on the role played by international management standards certification. We test the hypothesis that, accounting for technological innovation (product and process) and other variables related to technological capabilities, international standards are conducive to higher productivity, through improved management practices and business organization. In line with the requirement of continuous improvement implied by most international standards, the main findings show that the possession of an internationally recognized standard certificate leads to significant productivity premium. We further find that the effect of certification on productivity is particularly strong for firms with technological innovation, located in southern provinces, and operating in more scale-intensive industries.     

Media effects on sustainable food consumption. How newspaper coverage relates to supermarket expenditures

Information provision is often considered to have an important role to play in changing consumers' choices. However, there is still no consensus on the mechanisms by which information might influence specific consumer expenditures, especially in relation to environmentally friendly food products. This paper explores whether the public debate on sustainable consumption in UK broadsheets and tabloids relates to observed consumers' expenditures. It does so by relating the number of published articles on selected sustainability topics to consumers' food expenditure in a leading UK supermarket from May 2009 to May 2011, using regression analysis. We selected only regular supermarket's shoppers who frequently buy the Sunday editions of the analyzed newspapers. Results indicate very sparse and inconsistent correlations suggesting that the impact of information is only minimally effective. The number of newspaper articles relates mainly to expenditures on organic, wholegrain and low salt products, possibly indicating a preference for healthy food. No consistent effects are observed when media target a change in more general food categories (e.g. a reduction in food of animal origin), although we observed some influence on purchases of fish. Finally, results indicate some correlations with purchases of meat for the readers of the Telegraph. In order to contextualize some of the results, we applied content analysis to a subsample of published articles on organic food. The qualitative approach shows that the framing of the news is important: change is positively related to information proposed uncritically; and negatively to information contextualized as a highly structured debate.
