The SDGs give an overview of the world's development challenges of the present and the coming decades and set a new global agenda for more inclusive and sustainable development and growth. These challenges also represent opportunities for social innovations and the creation of scalable and financially self-sustaining solutions by businesses and (social) entrepreneurs. Examples of solutions to social and ecological challenges are for instance providing low-income communities with access to affordable, quality products and services in areas such as water and sanitation, energy, health, education and finance. New business models can meet customer demands by providing solutions and thereby create opportunities for low-income people as employees, suppliers and distributors.
The article studies a novel approach of inflation modeling in economics. We utilize a stochastic differential equation (SDE) of the form dXt=aXtdt+bXtdBtH, where dBtH is a fractional Brownian motion in order to model inflationary dynamics. Standard economic models do not capture the stochastic nature of inflation in the Eurozone. Thus, we develop a new stochastic approach and take into consideration fractional Brownian motions as well as Lévy processes. The benefits of those stochastic processes are the modeling of interdependence and jumps, which is equally confirmed by empirical inflation data. The article defines and introduces the rules for stochastic and fractional processes and elucidates the stochastic simulation output.
