This is an author's accepted manuscript of an article published in: "Mathematical and Computer Modelling of Dynamical Systems: Methods, Tools and Applications in Engineering and Related Sciences"; Volume 20, Issue 6, 2014; copyright Taylor & Francis; available online at: http://dx.doi.org/10.1080/13873954.2013.843572 ; Taking into account available data from 2002 to 2009 about the market share percentages of the Spanish mobile telecommunications service providers, a dynamic diffusion model to study the evolution of the clients' change between the different companies during the period 2010–2016 is proposed. The constructed model provides a tool for forecasting short-term trends about the customers' preferences with respect to mobile network operators taking into account both, autonomous decisions due to direct marketing and advertising strategies, and also decisions adopted through interaction via social influence. The model can provide insights to companies for designing strategies in order to gain market share. ; This work has been partially supported by the FIS PI-10/01433; the Spanish Government and European Regional Development Fund (FEDER) [grant number MTM2009-08587]; and the Universitat Politecnica de Valencia [grant number PAID06-11-2070]. ; Cervelló Royo, RE.; Cortés, J.; Santonja, F.; Villanueva Micó, RJ.

Global financial crisis and changes in sovereign debts ratings have affected the Latin American financial markets and their economies. However, Latin American s relative resilience to the more acute rise in risk seen in other regions like Europe during last years is offering investors new options for improving risk-return trade-offs. Therefore, forecasting the future of economic situation involves high levels of uncertainty. The Country Risk Score (CRS) represents a broadly used indicator to measure the current situation of a country regarding measures of economic, political, and financial risk in order to determine country risk ratings. In this contribution, we present a diffusion model to study the dynamics of the CRS in 18 Latin American countries which considers both the endogenous effect of each country policies and the contagion effect among them. The model predicts quite well the evolution of the CRS in the short term despite the economic and political instability. Furthermore, the model reproduces and forecasts a slight increasing trend, on average, in the CRS dynamics for almost all Latin American countries over the next months. ; This work has been partially supported by the Spanish M.C.Y.T.
