Publicación Modelación de los mercados accionarios de Estados Unidos, Brasil, Chile y Colombia mediante ecuaciones diferenciales estocásticas de segundo orden : un enfoque no paramétrico en contextos de volatilidad política-económica(Universidad EAFIT, 2026-03-12) Tavera Pérez, Fausto Dario; Pérez Monsalve, Juan PabloThis study models the volatility dynamics of the stock markets of the United States, Brazil, Chile, and Colombia during recent presidential election periods using stochastic processes and nonparametric statistics. The S&P 500, BOVESPA, IPSA, and COLCAP indices are analyzed through second-order stochastic differential equations and Nadaraya-Watson nonparametric estimators to identify differences in volatility structures between developed and emerging markets. Results reveal differentiated patterns of volatility persistence and transmission across markets, with greater intensity during preelectoral periods. These findings are useful for institutional investors and portfolio managers in the design of hedging strategies during electoral cycles, as well as for financial regulators and central banks interested in minimizing market disruptions associated with political uncertainty.
