A boa nutrição é fundamental para se construírem vidas saudáveis, meios de subsistência fortes e resilientes, e economias prósperas. Em sua ausência, a construção é feita em areia movediça. Crianças com atraso de crescimento não se desenvolvem adequadamente e, em especial,...

Una buena nutrición es fundamental para promover vidas saludables, medios de subsistencia sólidos y resistentes, y economías prósperas. Sin ella, estos empeños se asientan sobre terreno inestable. Los niños con retraso de crecimiento no pueden crecer ni desarrollarse adecuadamente, y...

At the 2013 Nutrition for Growth Summit in London, 96 signatories (governments, civil society organizations, donors, United Nations’ agencies, and businesses) agreed to support the creation of an annual report on global nutrition that would be authored by an independent expert group, in...

Une alimentation équilibrée est le socle sur lequel reposent des vies saines, des moyens de subsistance solides et durables et des économies prospères. En l’absence de ce socle, leur construction s’appuie sur des sables mouvants. Les enfants souffrant d’un retard de croissance ne...

Good nutrition is the bedrock upon which to build healthy lives, strong and resilient livelihoods, and thriving economies. In its absence, their construction takes place on quicksand. Stunted children fail to grow and develop properly, with impairment to brains and immune systems being...

Ziel dieses Beitrages ist es, die Zusammenhänge zwischen den Binomialmodellen der Operationsbewertung (Replikation bzw. Methode der risikoneutralen Wahrscheinlichkeiten) und dem Black/Scholes Modell aufzuzeigen und zu analysieren...

We introduce a new analytical approach to price American options. Using an explicit and intuitive proxy for the exercise rule, we derive tractable pricing formulas using a short-maturity asymptotic expansion. Depending on model parameters, this method can accurately price options with...

In this paper we construct arbitrage-free market models of stochastic volatility type for one stock, one bank account and a finite family of European call options with various strikes and maturities. We first introduce local implied volatilities and price level as market observables which...

In empirical modeling, there have been two strands for pricing in the options literature, namely the parametric and nonparametric models. Often, the support for the nonparametric methods is based on a benchmark such as theBlack-Scholes model with constant volatility. In this paper, we examine...
